Who's here from professor stick? Probably just me cuz there is just so many flat earther here and will probably make hate reply to this cuz I mention Prof. Stick
Hello, welcome to the channel. I encourage constructive and respectful comments, regardless of opinion. I discourage hostility or disrespect, and will delete comments (I am aware of) that I think are uncivil.
I appreciate the effort you took to explain your experiment. The correspondence between the theoretical principles involved and the schematic of your device is quite clear. Kudos on your results considering your low budget build.
Josh Levine I also love the style of his experiments and his delivery, I’m just very confused about how a gyrocompass works I guess. I always thought magnetism had zero to do with a Gyrocompass 🧭 -Waffa (CZC admin)
Some minor effects that might disturb your gyro 1. The electric motor has magnets. The magnetic fiels of the earth will put a force to the magnets used in the motors. 2. Some parts of your gyrocompass are made of iron. Even if they are not magnetic now the earth magnet fiel will try to turn them into a north south direction. 3. Some parts of your gyro are generatong some kind of air stream, so the tiny forces of these airflow might affect your gyrocompass. This is no offence, I thought about similar experiments (I'm not a flat earther) but I feared all the disturbing effect might be bigger than the forces that should make the gyroscope into a gyro compass. Kudos on your courage.
Thanks for the comments! Regarding points 1 and 2, you are right, and that is why this gyrocompass does not point perfectly North. I did a follow-up experiment with magnetic equilibrium in different places to show that, regardless of the magnetic effects, the gyrocompass effect is still strong, and always makes it deflect toward North. See the link that I just added to the description of this video. Regarding point 3, that's a very good observation. In fact air flow coming off the flywheel can easily dominate other effects when using an instrument sensitive enough to detect Earth's rotation, as I discovered to my surprise when I started this project. That is why the flywheel is encased in a paper cowling, ensuring there is no net torque due to air currents, since they are confined to that cowling. I think I say that in the video but it might not have been clear.
This is a (2-axis) gyrocompass, not a (3-axis) gyroscope. When placed within a rotating system, a gyrocompass always points North. The second half of the video explains why that is.
@@GarbageGamer74 noted. Though i think its far better to build a somewhat practical use gyro clock with a gyroscope on each of three axis to detect any rotation with 3 ring gimbals to indicate time of day as well as the month by the rotation of the planet on its axis as well as around the sun.
@@GarbageGamer74 a youtube video series called "The Primer Fields" shows bowl shaped ceramic magnets that levitate freely inside each other which should make lovely maglev gimbals when used at each axle of each gimbal.
@@hintzofcolorconcepts There is another video on my channel (search for "gyroscope version 2") showing my build of a 3-axis gyroscope. It's much harder to build than a gyrocompass.
I was commenting in regards to the "Magnetic Coriolis" concept, so this is the Allias Effect comment from your other video, you asked me to post here. It wasn't my intention to say that all movement of a pendulum or gyro is due the the Allias Effect. Yes it is hard to do an experiment during a solar eclipse. Mr Allias didn't seem to be a fool from what I can tell. My intentions here are to say that if there is indeed a variation in pendulum, or perhaps gyro, operation during a solar eclipse, then it could point to another effect altogether, not just rotation of the earth. Regardless, I think this is a super important area to look into, even if the results are hard to reproduce. Honestly, to prove rotation of the earth through gyro procession would require many experiments all over the earth, which is maybe what we are seeing unfold here on UA-cam. We just need some cohesion between experiments... I'm as excited to understand this as you are, I just have the freedom of not knowing what is going on, which frees me from preconceptions of what is happening with these gyros and pendulums. But maybe that's my limitation.
Thanks for commenting here. In this video, when the flywheel is spinning, the boat's equilibrium position changes from 270 degrees to around 315 degrees. Do you have an idea how that could be explained as a consequence of the Allias Effect? I've tried, but I don't see a connection. I'm not trying to criticize the suggestion, just understand it. But at the moment, it's sort of like suggesting that the motion is caused by dark matter, or string theory, or the Russian government--I wouldn't know what to do with those either, lacking a hypothesized connection between cause and observed effect. Those are exaggerations of course, but I hope you understand the question I am asking. As for the need to do more experiments, I certainly welcome that, but I contend that the experiment shown in this video is strong evidence that the reference frame in which *I* live is rotating, since the observed motion is consistent with a rotating frame and inconsistent with a non-rotating frame. And, I hope I've provided enough details about my setup to allow others to replicate it, whether here in SF or elsewhere in the world. If not, I would be happy to answer any questions about that setup, or to run the experiment under different circumstances, etc.
I wasn't trying to say this movement is caused by the Allias Effect. I am just pointing out that we may not know all the forces that are coming into play here, IF the Allias Effect is confirmed to be accurate. I'm still learning about gyros, got a long way to go I think.
Fair enough. You're right that we may not know all the forces. Physics is by no means "complete". And you're also right that it's good to keep an open mind about these things.
Very nice presentation! I've been trying to setup a simple experiment for North finding, but I've not got it setup quite right yet. Kite string is not good for a suspension thread and there has to be a way to dampen out the wobble from touching the darn thing. I'm planning on using the weight that comes with the super precision gyroscope immersed in vegetable oil. I was thinking monofilament fishing line would work nicely. The other thing to do is not allow the gyroscope to go a full 360º. So I need a way to set the rest point at the top. My only other worry is that the gyro can settle before it winds down. Also, would that winding down produce the same torque effect that you showed when you turned your motor on then off? I do not have a satisfactory way of keeping the gyro spinning at this point. My hope is that bearing friction, being parallel to the axis of rotation, would produce zero precession as the cross product would be zero. Have you seen Ice Skater's video?
At one point I experimented with using thin sewing thread to suspend the gyro apparatus as part of an attempt to build a better pitch bearing to make a true gyroscope. The sewing thread worked pretty well for the yaw axis, since its restoring torque is very small, but I gave up on making it work for pitch, mainly because of the usual problem of balancing. I don't recall problems with wobble, but that design never got very close to working. Why not allow the full 360? From my early experiments, if you do not have the motor attached, you have two problems. First, the flywheel spins down too quickly, losing most of its angular momentum within a couple minutes. Sure, it takes about 10 minutes to stop entirely, but after a minute or so the remaining angular momentum is slow low that the effects we're trying to measure are just too small for amateur equipment to detect. Second, unless you manage to keep the flywheel perfectly vertical, you'll get that torque due to spin down. For those reasons, I switched to designs that keep the motor running, which is annoying because the battery pack is quite heavy and awkward. One idea I had but didn't pursue is to use some solar panels and a bright spotlight to power it. You're talking about this video, right? ua-cam.com/video/-3ELhspVAUY/v-deo.html I have seen it, yes. I gave it the thumbs up. :)
That's the video. My understanding is that the gyroscope doesn't care which end of the spin axis is aligned with the local meridian. I could be wrong of course. So if you're overshooting by a lot, it takes much longer to settle. Rigging the gyroscope like a plumb bob is not super difficult. At least not under the high precision gaze of the Mark I eye ball 😉. That said, I think my video with the gyro suspended by the kite string is showing momentum being transferred to the string. The torque has to come from somewhere. The wobble I induced by spinning it up also took a while to settle. Obviously the weight is going to be providing a gravitational torque. Having that swing like a chaotic pendulum is not healthy. I certainly do agree with you that the gyroscope gives a very short time of useful angular momentum to work with. The flywheel is only about 111g which is not a lot of mass. It's way better than a TEDCO. Better be for that kind of money!!! Anyway, I did enjoy this video and gave it a thumbs up. There are not enough people showing that "simple" North finding is proof of rotation. It's also nice to see how other people approach the problem. For my part, the "Holy Grail" is actually having a gyroscope point to the same location in space as the earth rotates. It's a very tall order indeed! It is quite clear that most people don't appreciate that fact. What I'm currently working on is getting around the static friction issue by deliberately inducing precession with a mass and spinning the rotor in both directions. I will also be measuring the period of the flywheel, precession, and the angle of inclination that the arm the rotor mounts to has. That part is in line with the angular momentum. Fun stuff! Also time consuming and getting expensive.
Re "the gyroscope doesn't care which end": the spin axis vector, as defined by the right hand rule, wants to point North. If you try to point it South, it is in unstable equilibrium; a slight perturbation will send it North. Interestingly, my experiments show that the gyrocompass (at least as I built it) isn't very sensitive to initial direction, unlike a magnetic compass. A mag compass oscillates back and forth like a pendulum, with amplitude dependent on initial deviation, but the gyrocompass seems to just move steadily (but slowly) toward North (or wherever it finds equilibrium, which depends on magnetic torque), then oscillate chaotically around that point indefinitely. I don't know why it never settles down the way a mag compass does. I suspect the non-zero viscosity of the water is involved. I agree a true gyroscope pointing consistently in space for an extended period of time would be an even more convincing demonstration. One of my other videos shows my best attempt so far, which is only so-so, holding its position only for a couple minutes at a time. My apartment is littered with the remains of inadequate designs. :D Re expensive: tell me about it! I've already spent way more than I should have on tools and hardware. The gyro itself was among the cheaper components. :/
It's funny how all those nickels and dimes add up over time. It becomes an obsession. If it could be done in the 19th century, why not the 21st? Of course, inertial navigation systems have been relying on these principles for years. They just cost thousands of dollars.
This definition of a gyrocompass states: A gyrocompass is a type of non-magnetic compass which is based on a fast-spinning disc and the rotation of the Earth to find geographical direction automatically. The use of a gyrocompass is one of the seven fundamental ways to determine the heading of a vehicle. The magnetism 🧲 you’re referring to in your video... could you please elaborate on that. At this point I’m very confused running across your video... -Waffa (CZC admin)
@@WAFFAHOUSE Yes, that's right. The electric motor contains a permanent magnet, and that magnet is affected by the Earth's magnetic field, making the boat act like a magnetic compass. I added additional permanent magnets in approximately the opposite orientation to minimize the magnetic compass effect so that the gyrocompass effect would be as strong as possible. You may want to look at the follow-on video linked in the description where I repeat the experiment with magnetic equilibrium in different places.
Ah I see... So do most of these that are used "in the field" use additional mags like you did in your experiement to counter the magnetic field? -Waffa (CZC admin) ps Appreciate you explaining that to me. Starting to make a lot more sense to me now...@@GarbageGamer74
@@WAFFAHOUSE I don't know much about industrial gyrocompasses, but I assume they use more sophisticated motors that are not affected by external magnetic fields. Balancing the magnetic forces like I've done seems too imprecise and unreliable in a device meant for navigation.
Yes and no. In the setup shown in this video, yes, it can and does detect the Earth's rotation. However, the flywheel I am using came with a two-axis gimbal (you see it in a lot of other gyroscope videos on UA-cam), and that gimbal has too much friction to detect such slow rotation.
Have you tested this at different elevations and other variations to ensure a constant 15° “drift”? There were and still are ongoing tests using a laser gyro by a group of engineers, they’ve had mixed results of “drift” dependent on elevation and other factors. As much as 7-8°.
@@UpperDarbyDetailing you’re just making claims and screaming “nuh uh” when we’ve demonstrated this to you multiple times. Maybe for once, one of you dumbasses could try to prove the globe instead of appealing to explanations.
@@Truearthtruman - "they’ve had mixed results of “drift” dependent on elevation and other factors. As much as 7-8°. That is a flat out lie.

Sorry if this is a stupid question but I've watched this twice now and still don't understand how the gyrocompass acts like your example passenger jumping onto the earth and having to catch up his speed. All of the parts of the gyroscope were, relative let's say to the center of the Earth, already rotating with the same angular velocity as the surface of the Earth, as was the water, as was the container holding the water, the table, etc. If the little boat somehow _weren't_ rotating with the Earth, if it were instead hovering in some stationary position like a satellite, it would gradually bump into the side of the still-rotating container, no? Of course it will drift a bit because water isn't a solid, but the average movement of the water, held inside the container so it has no choice, is still with the direction of rotation, isn't it? I thought the fact that gyroscopes "choose" some axis to maintain upright with respect to only works if you choose an inertial reference frame that is outside of the Earth itself and not susceptible to its movement (like how in the Newtonian era they assumed some stars were not moving and used those as reference points). For example if I plop a big asteroid at a fixed position in space--one that magically and quite literally does not move ever--and I can somehow start my gyroscope on the Earth's surface with the upright position pointed at that asteroid, over the course of 24 hours it will appear to me as if the gyroscope is tilting by some unseen force, when in reality it's just a fictitious side effect of my position on the Earth rotating away from the asteroid and causing the direction of the gyroscope's angular momentum to change (thus producing a directional torque but no change in magnitude). And, as I understand it, the way you put this to work as a compass is to then just mark off the Earth's north pole somewhere with respect to the asteroid, start the gyroscope up, and lock one of the gimbals in place so that it can only tilt on one axis. If that's the case and I haven't insanely misunderstood frames of reference and conservation of angular momentum, I just don't see how the passenger analogy fits in. What component is "catching up" to the speed of the Earth here?
Good questions. I'll try to address each; feel free to ask for further clarification. How is the gyrocompass like a passenger experiencing a catch-up force? As you say, the water, table, and boat are already rotating with the Earth, so they experience no catch-up torque. But the flywheel is *not* rotating with the Earth; it is rotating in a different direction. A rigid object can only spin around one axis at a time, and the flywheel's spin axis is not aligned with the Earth's rotation axis. If the gyro were bolted to the Earth, as a passenger, the Earth would force the flywheel's spin axis direction to change over time. Spin direction only changes due to an applied torque, just as linear speed only changes due to an applied force. That is the passenger torque. The next part of your comment refers to what I call an "ideal gyroscope": a gyroscope with perfectly balanced and frictionless gimbals, able to turn in any direction. First, note that an ideal gyroscope does not care about *motion* at all, since that involves linear forces, and its gimbals are perfectly balanced so that linear forces are not transmitted to the flywheel. What an ideal gyroscope cares about is absolute *direction*; specifically, because there is no friction or imbalance, it experiences no torque, so its spin axis direction in 3D space will remain constant. So, if an ideal gyro's spin axis is pointed at a motionless asteroid, it will remain pointed at it *if* the asteroid is infinitely far away. But the gyrocompass is not an ideal gyroscope because it is constrained to rotate in the horizontal plane. It therefore experiences the "passenger catch-up" torque I explained above; again, think about what the flywheel would feel if its spin axis could not rotate at all with respect to the Earth's surface, as the Earth rotates. For reasons explained in the video, in a gyrocompass, that torque causes the flywheel's spin axis to precess until it is pointing North, such that the spin axis is as close to the Earth's spin axis as it can get. It will then continue to point North because any time it deviates (for example, because it wants to keep pointing in the same direction in 3D space), it immediately feels the restoring torque caused by the Earth's rotation. There is no need to calibrate the gyrocompass ahead of time; it always seeks North (or South, if you use the left-hand rule instead) because it always seeks to align its own spin axis with the Earth's.
Set the gyro axis to your Latitude, so that when North rotation is found, the axis will be parallel with the Earth axis and its rotation will be the same as the Earth.
Raise the end that will be turning CCW higher than the CW end, so it can orient itself to run parallel to the Earth axis. Not parallel with the water level.
Ah, I understand now: rotate the flywheel housing to point the spin axis 38 degrees (my latitude) above the horizon. That's a novel idea, but what would it show? For example, do you have a hypothesis for how the boat's movement would be different from the original experiment? Naively, I would expect it to behave basically the same.
I watched Vsauce and it says that a plane traveling opposite to the direction of the eraths rotation is faster than traveling along where it rotates and its been proven.
I wonder if there is a way to set up gyroscope in such a way that it can detect Earths orbit around the Sun? It will take 6 months for gyroscope to spin upside down and you will need to figure out how to cancel out the effect of Earths rotation on gyroscope. This way i think we can know if Earth orbits the Sun in circular fashion or vortex fashion. If circular fashion, then the Sun doesn't move. If vortex fashion, then the Sun orbits the Galaxy or another Star.
Well, a perfect gyroscope doesn't directly detect rotation; rather, its axis simply does not rotate, so if something else does, then the relative orientation can be seen to change. To detect the rotation of the Earth-Sun system ("Earth's orbit") with a gyroscope, start by pointing its axis at the Sun, then observe that 6 months later its axis points away from the Sun. To detect the galactic orbit, point the axis at the galactic center (Sagittarius A*), then observe ~120 million years later its axis points away from the center. The Sun is not co-orbiting any other star (other than those near the galactic center), so there is no star for which you could point a gyroscope axis at it, then regularly observe it being on the opposite side.
@@GarbageGamer74 I know the gyroscope maintains its axis and resists as long as its rotating, that tilting of gyroscope is only an appearance caused by earth rotating under it. There's a possibility the Sun is in 25,920 year long binary orbit with Sirius. ua-cam.com/video/90q1uIQ5PqM/v-deo.html Most solar systems within the galaxy are binary so the chances are the Sun is too.
Damn! This is the best helio video ever produced. A little complicated and I'm not sure if your flywheel is countering the rotation f the Earth or just the magnetic force from the onboard magnets, but a brilliant thesis and explanation nonetheless.The best part is you actually conducted and filmed the experiment. You obviously have a physics education. NDT look out - heliocentrism may have a new spokesperson. Thanks for making this. I'm assuming this is the simplest experiment to demonstrate the rotation of the earth since this is the one you chose, but thought I'd ask...is there anything simpler?
Thanks, I'm glad you liked the video! Note that this experiment doesn't directly imply anything about the structure of the solar system or shape of the Earth. Rather, it shows that, here on the surface of the Earth, we live in a rotating frame of reference. It furthermore shows that the axis of rotation has a component in the horizontal plane that is aligned with geographic North. Is there anything simpler? It depends on your definition of "simple". :) This experiment is the easiest to construct and most convincing of those I have attempted. A full 3D gyroscope is conceptually simpler, but my attempt at that was only a partial success due to the mechanical challenges; there is another video on my channel about that, "Foucault Gyroscope showing Earth Rotation, version 2". A Foucault pendulum is another candidate but also has a host of mechanical challenges, so I have not attempted to build one.
Wikipedia (article "Gyrocompass") has a written description, although I find their explanation unintuitive, which is why the second 2/3 of my video explains the operation in a way that makes sense to me.
How does this prove Earth’s rotation rather than the Aether drift moving around Earth as per the Silvertooth Effect published in Nature, Sagnac Effect and Airy’s Failure?
The gyrocompass shows that, on the surface of Earth, we are living in a rotating frame of reference. If there were no rotation, with all other assumptions held constant, then the gyrocompass would not deflect from its magnetic equilibrium because there would be no other source of torque. I welcome alternative hypotheses, but to be relevant, they must explain the deflection of the rotating gyrocompass. It sounds like you are suggesting the hypothesis of a moving Aether to explain those other experiments' results. But the hypothesis of a rotating Aether surrounding a non-rotating Earth would imply that the gyrocompass should not deflect. This experiment shows that it does, so we must reject or modify that hypothesis.
LBBstore It has already been proven that there is no Aether. Modern relativity and quantum mechanics are based on the null result of Michelson Morley. To get up to speed try this link. en.m.wikipedia.org/wiki/Michelson-Morley_experiment
I did that. Search my channel for "gyroscope version 2". It worked, but only for a few minutes at a time before falling out of balance. It is difficult to create a 3-axis gimbal that is both balanced and has low friction.
@@GarbageGamer74 Sadly, your data traces are so confusing I am having trouble understanding what it shows. I imagined that a properly supported gyro could just tilt up with the rising celestial sphere. I may be dense, but (for me) you assume too much is obvious. I have the gyro and am trying to design my own rig.
@@MumfordMicro Suppose you had a properly supported gyro, tilting up with the celestial sphere. Attach a laser pointer to the gyro. The dot will follow the sphere, right? That would be one trace, with the dot moving 15 degrees per hour. Now suppose the gyro is balanced only within a limited angle. When it exceeds that angle, it falls to one side. So you would have to manually set it back within its range of operation and repeat. That's the next trace. I did that over and over to get the traces shown. But I didn't always reset it properly (it is very delicate), so the traces show a mix of behaviors. Finally, in my setup, the laser bounces off of a mirror mounted to the gyro, rather than the laser being attached directly. That magnifies the motion by 2x, so it moves 30 degrees per hour when in the balanced region. Good luck making your own version! I look forward to seeing it.
@@GarbageGamer74 That was my vision. But, that doesn't seem to be what your laser dot does. Would you be willing to have a private email conversation about tall of this? I'm not hard to find.
MomoTheBellyDancer Bob like you does not understand the science. The earth doesn’t move. You will have to get over this fact. It’s science don’t you love science?
SpaghettiUpseti gyros do not actually detect earth movement. Ring lasers work differently than mechanical. I am happy you brought up the other movements in 3D space. Those movements are not detected by the ring laser. Neither is the movement of the assumption our entire “solar system” is moving through “space”. Take your time. I am here to help you
SpaghettiUpseti correct. When stationary on earth modern more accurate gyros will show no earth movement. Your science claims they should. Why don’t they?
Link: scienceworld.wolfram.com/physics/ComptonTube.html I see, interesting idea, you let particles settle so they are moving with the Earth, then turn around their enclosure and watch as they move due to their momentum. Unfortunately I think that's pretty far outside what I would be able to build! It is a similar principle to the Coriolis effect, since there you again have particles with angular momentum due to Earth rotation, and that angular momentum is conserved, this time as they swirl into a vortex. This is demonstrated really well by Smarter Every Day and Veritasium: ua-cam.com/video/aDorTBEhEtk/v-deo.html
Easiest ball earth explanation yet. Clear as lead. Just need a flywheel, motor and boat with only 1,034 easy steps plus a bottle of aspirin. You might just wake up in the morning.
LOL. :) This experiment is actually quite easy to build if you have the flywheel and motor. I spent $89 on that. It took less than a day to build the first working version out of household junk (plus the flywheel), although I made a few refinements before posting this video, the most significant of which was adding the balance magnets. In comparison, I spent a few hundred dollars and more than a week trying (and only halfway succeeding) to build a proper gyroscope with 3D gimbals. (That video is also on this channel.) However, note that this experiment doesn't say anything about the size or shape of the Earth. It only demonstrates that, living on the surface of the Earth, we are in a rotating frame of reference.
That is what I thought it would do too, when I first built this device, but it does not. The reason is somewhat subtle; the second half of the video (starting around 8:30) explains it.
Testable, Observable, Measurable, REPEATABLE is the yard stick requirement. Your claim is that your experiment would find true north using "Earths" rotation. If a gyroscope in a three way gimbal doesn't precess at all, until you physically move it proving non rotation, what is your experiment adding to this indisputable fact? Having a motor attached constantly to the gyroscope causes a contra-rotation effect stopping it from acting like a gyroscope and the magnets will cause it to act like a compass, just like any other compass. So i'm afraid it fails hands down.
Repeatable: I have a few other gyrocompass videos on my channel. I recommend looking at "Testing the Constant Torque Hypothesis", showing the results of four different runs simultaneously under varying conditions. Three-axis gyroscope: I have a video on that too, see "Gyroscope version 2". It isn't perfect, but it certainly moves. The other videos I've seen on UA-cam use gimbals with too much friction. You can see in this video, and the other I mentioned, that it does not simply behave like a magnetic compass when the motor is running. With the motor off, it finds a certain magnetic equilibrium. Then when the motor is on, it consistently deflects toward geographic North, regardless of where that is in relation to the magnetic equilibrium.
GarbageGamer74 You are really misunderstanding the game here. Earth is fixed. it does not rotate. If your experiment "shows rotation" then you are the first person ever to devise an experiment that does this. Either that or your experiment is wrong. This also would completely and utterly annihilate Einsteins nonsense about relativity, which is hypothesised as an excuse as to why there is no experiment that shows rotation. Do some research, and come back when you know who the real players of the game are. Next you'll be claiming you came from monkeys, or some such unproveable nonsense based on hearsay alone. ;D
@BULL SCHEIST lookup the video I ask Bob to watch above. Ring-laser gyroscopes MEASURE EARTH'S ROTATION. PERIOD. So do mechanical gyros, lookup the "gyro-compass".
@BULL SCHEIST I am an Aerospace Test Engineer with over twenty years experience building, testing, launching, and flying spacecraft. As part of that job I have been testing various models if ring-laser gyroscope for twenty years. The factory acceptance test of the Litton LN-200 is to verify it reads *Earth Rotation Rates* on all three axes. I have the Test Procedure in my possession and it CLEARLY states how to calculate the Earth rates for each axis based on the orientation of the gyro with respect to True North and the gravity vector. In fact if you put one of these units on a table and take a few minutes of data, you can tell the direction of true north and the LATITUDE of the gyro ON THE GLOBE. Litton has delivered over 30,000 of these units since the 1990s and Every Single One of them was tested by verifying "Earth Rates".

@ Edge Wyze "Sure is a challenge to show definitive curvature huh?" Actually it is not a challenge at all... Geodetic level survey over 1 mile, measure points every 50' along the mile, compare the elevation of these points with drops from a telescope at one end to a target at the other end, both telescope and target set at the same elevation, and you will get a perfect up and down 2" curvature. Takes 1/2 day to run with 3 people. (ex geodetic surveyor)
@@paulj1138 Yeah, but things in the distance get smaller. When you zoom in it offsets the measurements. That's why surveyors only measure two points equal distance from one center reference point. To compensate for "curvature" or in actuality it eliminates the error of angular resolution. Same reason hunters have to "sight in" their rifle scope. So they know where the bullet hits at a certain distance, and so they can compensate for shorter & longer shots. They'll sight it in at say 30 yards, get that on the bullseye, then move the target farther & closer to know how offset the shot will be. Doing this with their gun locked in to a special vice apparatus, & taking shots from the same reference point.
@ Edge Wyze. regarding diminishing size of objects (i.e. perspective). Sorry you are wrong. I assume from your equi distant measuring points from a central reference point you are are referring to equal fore and backsights when leveling. The reason for doing that is to remove colimation errors. You can look up how colimation error is removed by doing close and distant sights in conjunction with balanced fore and back sights. You should also research stadia measurement techniques which prove that 'level' does not rise or fall as a function of distance.
@@paulj1138 Dude, so at a football field every fifty feet there is curvature drop? Nope, but the theodolite scope will still show said offset reading. Hmmm
@ Edge wyze If I were to be pedantic (as surveyors are inclined to be ;) ) there is curvature every inch across the earth, but very small ;) - too small to be measured. Think of it this way.... 1) Use a geodetic level to measure the levels of every point 50' along a 1 mile length. 2) Pick any particular elevation that is workable at the location, and place a vertical marker at each 50' point, so the top of the marker is exactly at the chosen elevation (keep in mind the vertical markers will have different lengths because the elevation of the ground marker will vary - i.e. this is the real world where the mile long stretch is not perfectly flat) 3) If you want to go further, use some clear plastic tubing to make a water level as well, along the mile. You will see the water follows the same 'level' as the vertical markers. 4) Set up a telescope at one end and a target at the other with exactly the same elevation. If your vertical markers came up to the same elevation you will see the rise and fall over the mile. Sure, it takes effort to do this. Also it is not numerically dramatic as simply measuring curvature drop over 1 mile (i.e. 8 inches per mile drop, vs 2 inches = 50mm rise and fall over 1 mile). I think I said 25mm in an earlier post - please ignore that one - I am busy today. An advantage the rise and fall method does show immediately is the drop observed if using a theodolite is not related to 'perspective' at all. So having been a Geodetic Surveyor who has observed this a lot in the past, especially when conducting dam wall surveillance surveys, I am not blowing smoke up your backside. So my question for you is why is an up and down curve of 2" observed over 1 mile?
The earth must spin as the dizzy sensation you get when you bend down quickly and stand up is due to the increased centrifugal forces from the earths spin on your brain. but your experiment proves it just as well.
Feeling lightheaded after standing up quickly is not related to Earth's rotation. The increase in centrifugal acceleration over a few feet is physiologically insignificant; people at the poles feel the same effect even though there is no change in angular momentum for them. Furthermore, increasing centrifugal acceleration by standing up would decrease rather than increase weight, which would make it easier for the heart to maintain blood pressure in the brain. Consider: if you were a giant, 36000 km in height, then by standing up at the equator, your head would be in geostationary orbit, and your head's weight would be zero.
The motor caused vibration and water reacts on vibration and caused also vibration - waves. If you have a drill, turn it on and put it on the table and it will rotate. Rotation causes sound. But maybe I am wrong and I did not watch or understood correctly.
During the run, the water is completely still. Any waves would be visible due to the reflection of the overhead light as you can see at 0:43 when I put my hand in the water. I still don't understand what you mean about vibration causing rotation. I have a drill but there is no simple way to "turn it on" without holding it since I have to continuously squeeze the trigger. Could you link to a photo or video showing the setup you have in mind?
I can not fully judge your desing but where vibration is, is also rotation if the design allows it. You can block the trigger on your drill with a piece of paper. www.fs.wettzell.de/LKREISEL/G/LaserGyros.html www.laserfocusworld.com/articles/print/volume-36/issue-10/world-news/world-news/largest-ring-laser-gyroscope-lands-in-bavaria.html This machine is deep in a mountain to avoid any distubing vibration that could influence the measurements. But I do not know what they measured, maybe satans shake on the pillars of the earth ? Who knows ;) Maybe the scientists should have saved the millions for their gyro and just copied your design ;)
If vibration alone could cause rotation, that would violate conservation of angular momentum. If I put an electric toothbrush into a boat, do you predict that would rotate? As for the ring lasers, the idea there is to measure the speed of the earth's rotation extremely precisely. In contrast, a gyrocompass like mine merely shows that the earth *is* rotating without providing much information about the speed.
This is a terrible looking contraption. It's so totally goofy looking that it can't possibly be used to prove anything one way or another. In fact, it's simply laughable and rediculous. In effect, it's the OPPOSITE of "elegant" which is what a real nice universal 3 axis powered gyroscope would do to prove earth rotates or not. In fact, THIS video might be part of a larger "operation" (psyop_) to DIScredit any further look into a real elegant proof.
The equipment and water introduce the magnetic fields and effects of (flat) earth into your experiment and if anything you are proving vortex fields.. otherwise a useless endeavour...
just go out and buy and actual gyro and stop using this inaccurate device to prove the earth is spinning. Then take the gyro and set it on the floor and watch how it does not move for hours.
I think truewrldseeker meant "gyroscope" rather than "gyrocompass". There are plenty of UA-cam videos showing commercial gyrocompasses in action, so I don't know what value there would be in posting another.
Your title is "Gyrocompass showing effect of earth rotation" a real Gyrocompass does not show effect of earth rotation or curvature effect. It does not!. I do mean Gyrocompass not Gyroscope. google search "Robertson gyrocompass" for more information.
I agree that it has nothing to do with curvature. But rotation is essential. Quoting the Wikipedia article on gyrocompass: "A gyrocompass is a type of non-magnetic compass which is based on a fast-spinning disc and the rotation of the Earth". My video explains in detail how the Earth's rotation produces the observed gyrocompass movement. If the Earth is not rotating, then how do you explain the movement?
This video shows we live in a rotating frame of reference. You can build it yourself for less than $200 and it will work. As for curvature, search my channel for "horizon".
Wouldn't proving that an object is in orbit be proof enough? Especially if that object can be seen by people at ALL LATITUDES at DIFFERENT TIMES as it passes overhead? Anyone can go see the ISS pass overhead. There are two videos of it on my YT channel. Just by observing the times that the "object" rises above the horizon for some Observers while rising at later times for other observers? You can literally follow the ISS from different locations running north to south over the US and prove curvature that way. Give me your zip code or a nearby city and I'll tell you when to go see it yourself. My guess is that you REFUSE to even look.
Stuart Gray orbital mechanics requires the presumption of the R value.. it has never been independently verified. I get notifications on my phone when the “ISS” is above my location. “Where’s the curvature?” (Globehead points to sky) 😂 Tell me.. do you think they observed the curve when they came up with latitude and longitude?? 😆
@@nicholashpitts so have you ever SEEN the ISS yourself? What is your explanation for what it is? And how do you explain the SpaceX launches and landings? Fake?
Stuart Gray you need to explain it. Not me. Why can we detect no curvature at 59 miles, 177 miles, and 220 miles? You know about these devices but fail to mention their consistent drift procession, and are also unable to even fully define or prove your theories on what causes what you are experiencing. Rest assured there is no curvature or motion of earth. You will figure it out. Just don’t give up. I have PERSONALLY directly observed the ISS. But not curvature. Have you personally looked at the stars and planets in real time through high magnification?
The earth doesn’t move.. there is no coriolis effect. Gyros have proven this time and time again. You think your gyrocompass detects rotation when literally nothing else does.. Cool story bro.
Nicholas Pitts - Sorry but ring-laser gyros DO show rotation. Search YT for "Honeywell ADIRU alignment" and watch a video where the Honeywell Engineer explains that their devices DO measure earth rotation as part of the pre-flight test of the gyros. DO you think it is possible for this engineer to LIE to FAA inspectors?
Stuart Gray you don’t know what light is, or the sun. Your detector is simply measuring the movement of the sun. If the earth was moving we would be able to verify it not INFER it!
Stuart Gray you don’t know what light is, or the sun. Your detector is simply measuring the movement of the sun. If the earth was moving we would be able to verify it not INFER it!
Stuart Gray besides what about all of the other apparent movements you believe in that this is not detecting? Why does it only detect the earth rotation? And if the atmosphere is locked with the earth how is it even able to detect it? You don’t realize your own belief system contradicts itself. All you have to do is pay attention to what you think
Nicholas Pitts - "you don’t know what light is, or the sun." Actually I am an Electrical Engineer (the one's who expertise is the propagation of electromagnetic radiation - LIGHT). I actually build, test, launch and operate spacecraft in earth orbit that use the Sun as a calibration source for the science instruments so I am fairly sure I know more about the sun than someone who has never graduated high school or taken an actual physics class. "Your detector is simply measuring the movement of the sun." No - these devices are used for guidance of missiles, fighter jets, and drones. They are FAR MORE then capable of reading earth's rotation. However since earth's rotation is Perfectly predictable and measurable anywhere on the surface of the planet that we use it as a Measurement Standard when testing or calibrating our gyros. I have performed both the Gyo Performance of one of these units, and the pre-launch aliveness tests where we specifically HAVE TO measure earth rotation while the vehicle sits motionless or the Gyros are BROKEN. "If the earth was moving we would be able to verify it" We do verify it with optical observations of other objects in the sky, Gyro-scope based measurements DO detect earth rotation. It is the basis for the GYRO-COMPASS used by every world military and shipping company since about 1910. Look them up. Th Us military used gyro-compasses in artillery targeting scopes. Google "Sperry Gyro-Compass Mark XIV"

Some minor effects that might disturb your gyro
1. The electric motor has magnets. The magnetic fiels of the earth will put a force to the magnets used in the motors.
2. Some parts of your gyrocompass are made of iron. Even if they are not magnetic now the earth magnet fiel will try to turn them into a north south direction.
3. Some parts of your gyro are generatong some kind of air stream, so the tiny forces of these airflow might affect your gyrocompass.
This is no offence, I thought about similar experiments (I'm not a flat earther) but I feared all the disturbing effect might be bigger than the forces that should make the gyroscope into a gyro compass.
Kudos on your courage.
Thanks for the comments! Regarding points 1 and 2, you are right, and that is why this gyrocompass does not point perfectly North. I did a follow-up experiment with magnetic equilibrium in different places to show that, regardless of the magnetic effects, the gyrocompass effect is still strong, and always makes it deflect toward North. See the link that I just added to the description of this video.
Regarding point 3, that's a very good observation. In fact air flow coming off the flywheel can easily dominate other effects when using an instrument sensitive enough to detect Earth's rotation, as I discovered to my surprise when I started this project. That is why the flywheel is encased in a paper cowling, ensuring there is no net torque due to air currents, since they are confined to that cowling. I think I say that in the video but it might not have been clear.
show a clock that uses the gyro's orientation to point an arrow to the time of day and this wouldn't be a waste of time and energy.
This is a (2-axis) gyrocompass, not a (3-axis) gyroscope. When placed within a rotating system, a gyrocompass always points North. The second half of the video explains why that is.
@@GarbageGamer74 noted. Though i think its far better to build a somewhat practical use gyro clock with a gyroscope on each of three axis to detect any rotation with 3 ring gimbals to indicate time of day as well as the month by the rotation of the planet on its axis as well as around the sun.
@@GarbageGamer74 a youtube video series called "The Primer Fields" shows bowl shaped ceramic magnets that levitate freely inside each other which should make lovely maglev gimbals when used at each axle of each gimbal.
@@hintzofcolorconcepts There is another video on my channel (search for "gyroscope version 2") showing my build of a 3-axis gyroscope. It's much harder to build than a gyrocompass.
Amazing video guessing all the dislikes are from flat earthers?
People don't like when what they believe is proven wrong.
I was commenting in regards to the "Magnetic Coriolis" concept, so this is the Allias Effect comment from your other video, you asked me to post here.
It wasn't my intention to say that all movement of a pendulum or gyro is due the the Allias Effect. Yes it is hard to do an experiment during a solar eclipse. Mr Allias didn't seem to be a fool from what I can tell. My intentions here are to say that if there is indeed a variation in pendulum, or perhaps gyro, operation during a solar eclipse, then it could point to another effect altogether, not just rotation of the earth. Regardless, I think this is a super important area to look into, even if the results are hard to reproduce.
Honestly, to prove rotation of the earth through gyro procession would require many experiments all over the earth, which is maybe what we are seeing unfold here on UA-cam. We just need some cohesion between experiments... I'm as excited to understand this as you are, I just have the freedom of not knowing what is going on, which frees me from preconceptions of what is happening with these gyros and pendulums. But maybe that's my limitation.
Thanks for commenting here. In this video, when the flywheel is spinning, the boat's equilibrium position changes from 270 degrees to around 315 degrees. Do you have an idea how that could be explained as a consequence of the Allias Effect? I've tried, but I don't see a connection. I'm not trying to criticize the suggestion, just understand it. But at the moment, it's sort of like suggesting that the motion is caused by dark matter, or string theory, or the Russian government--I wouldn't know what to do with those either, lacking a hypothesized connection between cause and observed effect. Those are exaggerations of course, but I hope you understand the question I am asking.
As for the need to do more experiments, I certainly welcome that, but I contend that the experiment shown in this video is strong evidence that the reference frame in which *I* live is rotating, since the observed motion is consistent with a rotating frame and inconsistent with a non-rotating frame. And, I hope I've provided enough details about my setup to allow others to replicate it, whether here in SF or elsewhere in the world. If not, I would be happy to answer any questions about that setup, or to run the experiment under different circumstances, etc.
I wasn't trying to say this movement is caused by the Allias Effect. I am just pointing out that we may not know all the forces that are coming into play here, IF the Allias Effect is confirmed to be accurate. I'm still learning about gyros, got a long way to go I think.
Fair enough. You're right that we may not know all the forces. Physics is by no means "complete". And you're also right that it's good to keep an open mind about these things.
Do one experiment to show things can float in vacuum.
24 flat earthers disliked the video
@Random Clicks Was this a legit response or just another trolling?
Very nice presentation! I've been trying to setup a simple experiment for North finding, but I've not got it setup quite right yet. Kite string is not good for a suspension thread and there has to be a way to dampen out the wobble from touching the darn thing. I'm planning on using the weight that comes with the super precision gyroscope immersed in vegetable oil.
I was thinking monofilament fishing line would work nicely. The other thing to do is not allow the gyroscope to go a full 360º. So I need a way to set the rest point at the top.
My only other worry is that the gyro can settle before it winds down. Also, would that winding down produce the same torque effect that you showed when you turned your motor on then off? I do not have a satisfactory way of keeping the gyro spinning at this point. My hope is that bearing friction, being parallel to the axis of rotation, would produce zero precession as the cross product would be zero.
Have you seen Ice Skater's video?
At one point I experimented with using thin sewing thread to suspend the gyro apparatus as part of an attempt to build a better pitch bearing to make a true gyroscope. The sewing thread worked pretty well for the yaw axis, since its restoring torque is very small, but I gave up on making it work for pitch, mainly because of the usual problem of balancing. I don't recall problems with wobble, but that design never got very close to working.
Why not allow the full 360?
From my early experiments, if you do not have the motor attached, you have two problems. First, the flywheel spins down too quickly, losing most of its angular momentum within a couple minutes. Sure, it takes about 10 minutes to stop entirely, but after a minute or so the remaining angular momentum is slow low that the effects we're trying to measure are just too small for amateur equipment to detect. Second, unless you manage to keep the flywheel perfectly vertical, you'll get that torque due to spin down. For those reasons, I switched to designs that keep the motor running, which is annoying because the battery pack is quite heavy and awkward. One idea I had but didn't pursue is to use some solar panels and a bright spotlight to power it.
You're talking about this video, right?
ua-cam.com/video/-3ELhspVAUY/v-deo.html
I have seen it, yes. I gave it the thumbs up. :)
That's the video.
My understanding is that the gyroscope doesn't care which end of the spin axis is aligned with the local meridian. I could be wrong of course. So if you're overshooting by a lot, it takes much longer to settle.
Rigging the gyroscope like a plumb bob is not super difficult. At least not under the high precision gaze of the Mark I eye ball 😉. That said, I think my video with the gyro suspended by the kite string is showing momentum being transferred to the string. The torque has to come from somewhere. The wobble I induced by spinning it up also took a while to settle. Obviously the weight is going to be providing a gravitational torque. Having that swing like a chaotic pendulum is not healthy.
I certainly do agree with you that the gyroscope gives a very short time of useful angular momentum to work with. The flywheel is only about 111g which is not a lot of mass. It's way better than a TEDCO. Better be for that kind of money!!!
Anyway, I did enjoy this video and gave it a thumbs up. There are not enough people showing that "simple" North finding is proof of rotation. It's also nice to see how other people approach the problem. For my part, the "Holy Grail" is actually having a gyroscope point to the same location in space as the earth rotates. It's a very tall order indeed! It is quite clear that most people don't appreciate that fact. What I'm currently working on is getting around the static friction issue by deliberately inducing precession with a mass and spinning the rotor in both directions. I will also be measuring the period of the flywheel, precession, and the angle of inclination that the arm the rotor mounts to has. That part is in line with the angular momentum.
Fun stuff! Also time consuming and getting expensive.
Re "the gyroscope doesn't care which end": the spin axis vector, as defined by the right hand rule, wants to point North. If you try to point it South, it is in unstable equilibrium; a slight perturbation will send it North.
Interestingly, my experiments show that the gyrocompass (at least as I built it) isn't very sensitive to initial direction, unlike a magnetic compass. A mag compass oscillates back and forth like a pendulum, with amplitude dependent on initial deviation, but the gyrocompass seems to just move steadily (but slowly) toward North (or wherever it finds equilibrium, which depends on magnetic torque), then oscillate chaotically around that point indefinitely. I don't know why it never settles down the way a mag compass does. I suspect the non-zero viscosity of the water is involved.
I agree a true gyroscope pointing consistently in space for an extended period of time would be an even more convincing demonstration. One of my other videos shows my best attempt so far, which is only so-so, holding its position only for a couple minutes at a time. My apartment is littered with the remains of inadequate designs. :D
Re expensive: tell me about it! I've already spent way more than I should have on tools and hardware. The gyro itself was among the cheaper components. :/
It's funny how all those nickels and dimes add up over time. It becomes an obsession. If it could be done in the 19th century, why not the 21st? Of course, inertial navigation systems have been relying on these principles for years. They just cost thousands of dollars.
Thank you! I finally get it. Thanks for a very good explanation!
Thank you!
This definition of a gyrocompass states: A gyrocompass is a type of non-magnetic compass which is based on a fast-spinning disc and the rotation of the Earth to find geographical direction automatically. The use of a gyrocompass is one of the seven fundamental ways to determine the heading of a vehicle.
The magnetism 🧲 you’re referring to in your video... could you please elaborate on that. At this point I’m very confused running across your video...
-Waffa (CZC admin)
Are you using magnets to sort of offset the magnetism the motor your using has? I’ve watched the video several times now and I’m still very confused
@@WAFFAHOUSE Yes, that's right. The electric motor contains a permanent magnet, and that magnet is affected by the Earth's magnetic field, making the boat act like a magnetic compass. I added additional permanent magnets in approximately the opposite orientation to minimize the magnetic compass effect so that the gyrocompass effect would be as strong as possible. You may want to look at the follow-on video linked in the description where I repeat the experiment with magnetic equilibrium in different places.
Ah I see... So do most of these that are used "in the field" use additional mags like you did in your experiement to counter the magnetic field?

Appreciate you explaining that to me. Starting to make a lot more sense to me now...@@GarbageGamer74
@@WAFFAHOUSE I don't know much about industrial gyrocompasses, but I assume they use more sophisticated motors that are not affected by external magnetic fields. Balancing the magnetic forces like I've done seems too imprecise and unreliable in a device meant for navigation.
That gyro is sensitive enough to detect the rotation of the earth ?
Yes and no. In the setup shown in this video, yes, it can and does detect the Earth's rotation. However, the flywheel I am using came with a two-axis gimbal (you see it in a lot of other gyroscope videos on UA-cam), and that gimbal has too much friction to detect such slow rotation.
@@GarbageGamer74 ... if the device is not sensitive enough to detect earth rotation .... cant work as a gyroCompass

Sorry if this is a stupid question but I've watched this twice now and still don't understand how the gyrocompass acts like your example passenger jumping onto the earth and having to catch up his speed. All of the parts of the gyroscope were, relative let's say to the center of the Earth, already rotating with the same angular velocity as the surface of the Earth, as was the water, as was the container holding the water, the table, etc. If the little boat somehow _weren't_ rotating with the Earth, if it were instead hovering in some stationary position like a satellite, it would gradually bump into the side of the still-rotating container, no? Of course it will drift a bit because water isn't a solid, but the average movement of the water, held inside the container so it has no choice, is still with the direction of rotation, isn't it?
I thought the fact that gyroscopes "choose" some axis to maintain upright with respect to only works if you choose an inertial reference frame that is outside of the Earth itself and not susceptible to its movement (like how in the Newtonian era they assumed some stars were not moving and used those as reference points). For example if I plop a big asteroid at a fixed position in space--one that magically and quite literally does not move ever--and I can somehow start my gyroscope on the Earth's surface with the upright position pointed at that asteroid, over the course of 24 hours it will appear to me as if the gyroscope is tilting by some unseen force, when in reality it's just a fictitious side effect of my position on the Earth rotating away from the asteroid and causing the direction of the gyroscope's angular momentum to change (thus producing a directional torque but no change in magnitude). And, as I understand it, the way you put this to work as a compass is to then just mark off the Earth's north pole somewhere with respect to the asteroid, start the gyroscope up, and lock one of the gimbals in place so that it can only tilt on one axis. If that's the case and I haven't insanely misunderstood frames of reference and conservation of angular momentum, I just don't see how the passenger analogy fits in. What component is "catching up" to the speed of the Earth here?
Good questions. I'll try to address each; feel free to ask for further clarification.
How is the gyrocompass like a passenger experiencing a catch-up force? As you say, the water, table, and boat are already rotating with the Earth, so they experience no catch-up torque. But the flywheel is *not* rotating with the Earth; it is rotating in a different direction. A rigid object can only spin around one axis at a time, and the flywheel's spin axis is not aligned with the Earth's rotation axis. If the gyro were bolted to the Earth, as a passenger, the Earth would force the flywheel's spin axis direction to change over time. Spin direction only changes due to an applied torque, just as linear speed only changes due to an applied force. That is the passenger torque.
The next part of your comment refers to what I call an "ideal gyroscope": a gyroscope with perfectly balanced and frictionless gimbals, able to turn in any direction. First, note that an ideal gyroscope does not care about *motion* at all, since that involves linear forces, and its gimbals are perfectly balanced so that linear forces are not transmitted to the flywheel. What an ideal gyroscope cares about is absolute *direction*; specifically, because there is no friction or imbalance, it experiences no torque, so its spin axis direction in 3D space will remain constant. So, if an ideal gyro's spin axis is pointed at a motionless asteroid, it will remain pointed at it *if* the asteroid is infinitely far away.
But the gyrocompass is not an ideal gyroscope because it is constrained to rotate in the horizontal plane. It therefore experiences the "passenger catch-up" torque I explained above; again, think about what the flywheel would feel if its spin axis could not rotate at all with respect to the Earth's surface, as the Earth rotates. For reasons explained in the video, in a gyrocompass, that torque causes the flywheel's spin axis to precess until it is pointing North, such that the spin axis is as close to the Earth's spin axis as it can get. It will then continue to point North because any time it deviates (for example, because it wants to keep pointing in the same direction in 3D space), it immediately feels the restoring torque caused by the Earth's rotation. There is no need to calibrate the gyrocompass ahead of time; it always seeks North (or South, if you use the left-hand rule instead) because it always seeks to align its own spin axis with the Earth's.
I appreciate the time you took to reply to my misunderstandings. Thanks
Set the gyro axis to your Latitude, so that when North rotation is found, the axis will be parallel with the Earth axis and its rotation will be the same as the Earth.
I don't understand. Set the axis how?
Raise the end that will be turning CCW higher than the CW end, so it can orient itself to run parallel to the Earth axis. Not parallel with the water level.
Ah, I understand now: rotate the flywheel housing to point the spin axis 38 degrees (my latitude) above the horizon. That's a novel idea, but what would it show? For example, do you have a hypothesis for how the boat's movement would be different from the original experiment? Naively, I would expect it to behave basically the same.
I watched Vsauce and it says that a plane traveling opposite to the direction of the eraths rotation is faster than traveling along where it rotates and its been proven.
I wonder if there is a way to set up gyroscope in such a way that it can detect Earths orbit around the Sun? It will take 6 months for gyroscope to spin upside down and you will need to figure out how to cancel out the effect of Earths rotation on gyroscope. This way i think we can know if Earth orbits the Sun in circular fashion or vortex fashion. If circular fashion, then the Sun doesn't move. If vortex fashion, then the Sun orbits the Galaxy or another Star.
Well, a perfect gyroscope doesn't directly detect rotation; rather, its axis simply does not rotate, so if something else does, then the relative orientation can be seen to change. To detect the rotation of the Earth-Sun system ("Earth's orbit") with a gyroscope, start by pointing its axis at the Sun, then observe that 6 months later its axis points away from the Sun. To detect the galactic orbit, point the axis at the galactic center (Sagittarius A*), then observe ~120 million years later its axis points away from the center. The Sun is not co-orbiting any other star (other than those near the galactic center), so there is no star for which you could point a gyroscope axis at it, then regularly observe it being on the opposite side.
@@GarbageGamer74 I know the gyroscope maintains its axis and resists as long as its rotating, that tilting of gyroscope is only an appearance caused by earth rotating under it. There's a possibility the Sun is in 25,920 year long binary orbit with Sirius. ua-cam.com/video/90q1uIQ5PqM/v-deo.html Most solar systems within the galaxy are binary so the chances are the Sun is too.
Damn! This is the best helio video ever produced. A little complicated and I'm not sure if your flywheel is countering the rotation f the Earth or just the magnetic force from the onboard magnets, but a brilliant thesis and explanation nonetheless.The best part is you actually conducted and filmed the experiment. You obviously have a physics education. NDT look out - heliocentrism may have a new spokesperson. Thanks for making this. I'm assuming this is the simplest experiment to demonstrate the rotation of the earth since this is the one you chose, but thought I'd ask...is there anything simpler?
Thanks, I'm glad you liked the video!
Note that this experiment doesn't directly imply anything about the structure of the solar system or shape of the Earth. Rather, it shows that, here on the surface of the Earth, we live in a rotating frame of reference. It furthermore shows that the axis of rotation has a component in the horizontal plane that is aligned with geographic North.
Is there anything simpler? It depends on your definition of "simple". :) This experiment is the easiest to construct and most convincing of those I have attempted. A full 3D gyroscope is conceptually simpler, but my attempt at that was only a partial success due to the mechanical challenges; there is another video on my channel about that, "Foucault Gyroscope showing Earth Rotation, version 2". A Foucault pendulum is another candidate but also has a host of mechanical challenges, so I have not attempted to build one.
Fair enough. I will just direct anyone interested to your video, since your presentation is much, much better than I could ever explain it. Thx again.
Where I'm can read a description to understood what is it, and how it works?
Wikipedia (article "Gyrocompass") has a written description, although I find their explanation unintuitive, which is why the second 2/3 of my video explains the operation in a way that makes sense to me.
How does this prove Earth’s rotation rather than the Aether drift moving around Earth as per the Silvertooth Effect published in Nature, Sagnac Effect and Airy’s Failure?
The gyrocompass shows that, on the surface of Earth, we are living in a rotating frame of reference. If there were no rotation, with all other assumptions held constant, then the gyrocompass would not deflect from its magnetic equilibrium because there would be no other source of torque. I welcome alternative hypotheses, but to be relevant, they must explain the deflection of the rotating gyrocompass.
It sounds like you are suggesting the hypothesis of a moving Aether to explain those other experiments' results. But the hypothesis of a rotating Aether surrounding a non-rotating Earth would imply that the gyrocompass should not deflect. This experiment shows that it does, so we must reject or modify that hypothesis.
LBBstore It has already been proven that there is no Aether. Modern relativity and quantum mechanics are based on the null result of Michelson Morley. To get up to speed try this link. en.m.wikipedia.org/wiki/Michelson-Morley_experiment
Why can't you just point your gyro east, on a gimbal, and have it rise with the sky?
I did that. Search my channel for "gyroscope version 2". It worked, but only for a few minutes at a time before falling out of balance. It is difficult to create a 3-axis gimbal that is both balanced and has low friction.
@@GarbageGamer74 Sadly, your data traces are so confusing I am having trouble understanding what it shows. I imagined that a properly supported gyro could just tilt up with the rising celestial sphere. I may be dense, but (for me) you assume too much is obvious. I have the gyro and am trying to design my own rig.
@@MumfordMicro Suppose you had a properly supported gyro, tilting up with the celestial sphere. Attach a laser pointer to the gyro. The dot will follow the sphere, right? That would be one trace, with the dot moving 15 degrees per hour.
Now suppose the gyro is balanced only within a limited angle. When it exceeds that angle, it falls to one side. So you would have to manually set it back within its range of operation and repeat. That's the next trace. I did that over and over to get the traces shown. But I didn't always reset it properly (it is very delicate), so the traces show a mix of behaviors.
Finally, in my setup, the laser bounces off of a mirror mounted to the gyro, rather than the laser being attached directly. That magnifies the motion by 2x, so it moves 30 degrees per hour when in the balanced region.
Good luck making your own version! I look forward to seeing it.
@@GarbageGamer74 That was my vision. But, that doesn't seem to be what your laser dot does. Would you be willing to have a private email conversation about tall of this? I'm not hard to find.
When was 15 degrees per hour observed?
MomoTheBellyDancer Bob like you does not understand the science. The earth doesn’t move. You will have to get over this fact. It’s science don’t you love science?
SpaghettiUpseti they don’t.
SpaghettiUpseti ring lasers detect the sun moving. Mechanical and mems gyros detect no motion. They should according to your science.
SpaghettiUpseti gyros do not actually detect earth movement. Ring lasers work differently than mechanical. I am happy you brought up the other movements in 3D space. Those movements are not detected by the ring laser. Neither is the movement of the assumption our entire “solar system” is moving through “space”. Take your time. I am here to help you
SpaghettiUpseti correct. When stationary on earth modern more accurate gyros will show no earth movement. Your science claims they should. Why don’t they?
great job, i like how you try to perfect the experiment conditions
There's an rather unknown experiment to prove the earths rotation. It's called the Compton tube.
Link: scienceworld.wolfram.com/physics/ComptonTube.html
I see, interesting idea, you let particles settle so they are moving with the Earth, then turn around their enclosure and watch as they move due to their momentum. Unfortunately I think that's pretty far outside what I would be able to build!
It is a similar principle to the Coriolis effect, since there you again have particles with angular momentum due to Earth rotation, and that angular momentum is conserved, this time as they swirl into a vortex. This is demonstrated really well by Smarter Every Day and Veritasium:
ua-cam.com/video/aDorTBEhEtk/v-deo.html
Easiest ball earth explanation yet. Clear as lead. Just need a flywheel, motor and boat with only 1,034 easy steps plus a bottle of aspirin. You might just wake up in the morning.
LOL. :)
This experiment is actually quite easy to build if you have the flywheel and motor. I spent $89 on that. It took less than a day to build the first working version out of household junk (plus the flywheel), although I made a few refinements before posting this video, the most significant of which was adding the balance magnets. In comparison, I spent a few hundred dollars and more than a week trying (and only halfway succeeding) to build a proper gyroscope with 3D gimbals. (That video is also on this channel.)
However, note that this experiment doesn't say anything about the size or shape of the Earth. It only demonstrates that, living on the surface of the Earth, we are in a rotating frame of reference.
shouldn't it rotate once every 24h?
That is what I thought it would do too, when I first built this device, but it does not. The reason is somewhat subtle; the second half of the video (starting around 8:30) explains it.
It's not showing effect of earth's rotation. Its mass is not balanced.
Testable, Observable, Measurable, REPEATABLE is the yard stick requirement. Your claim is that your experiment would find true north using "Earths" rotation. If a gyroscope in a three way gimbal doesn't precess at all, until you physically move it proving non rotation, what is your experiment adding to this indisputable fact? Having a motor attached constantly to the gyroscope causes a contra-rotation effect stopping it from acting like a gyroscope and the magnets will cause it to act like a compass, just like any other compass.
So i'm afraid it fails hands down.
Repeatable: I have a few other gyrocompass videos on my channel. I recommend looking at "Testing the Constant Torque Hypothesis", showing the results of four different runs simultaneously under varying conditions.
Three-axis gyroscope: I have a video on that too, see "Gyroscope version 2". It isn't perfect, but it certainly moves. The other videos I've seen on UA-cam use gimbals with too much friction.
You can see in this video, and the other I mentioned, that it does not simply behave like a magnetic compass when the motor is running. With the motor off, it finds a certain magnetic equilibrium. Then when the motor is on, it consistently deflects toward geographic North, regardless of where that is in relation to the magnetic equilibrium.
GarbageGamer74
You are really misunderstanding the game here. Earth is fixed. it does not rotate. If your experiment "shows rotation" then you are the first person ever to devise an experiment that does this. Either that or your experiment is wrong. This also would completely and utterly annihilate Einsteins nonsense about relativity, which is hypothesised as an excuse as to why there is no experiment that shows rotation.
Do some research, and come back when you know who the real players of the game are. Next you'll be claiming you came from monkeys, or some such unproveable nonsense based on hearsay alone. ;D
bob question search UA-cam for "Honeywell ADIRU alignment" tell me what you find there ( hint it is proof that *you are full of shit* )
@BULL SCHEIST lookup the video I ask Bob to watch above. Ring-laser gyroscopes MEASURE EARTH'S ROTATION. PERIOD. So do mechanical gyros, lookup the "gyro-compass".
@BULL SCHEIST I am an Aerospace Test Engineer with over twenty years experience building, testing, launching, and flying spacecraft. As part of that job I have been testing various models if ring-laser gyroscope for twenty years. The factory acceptance test of the Litton LN-200 is to verify it reads *Earth Rotation Rates* on all three axes. I have the Test Procedure in my possession and it CLEARLY states how to calculate the Earth rates for each axis based on the orientation of the gyro with respect to True North and the gravity vector. In fact if you put one of these units on a table and take a few minutes of data, you can tell the direction of true north and the LATITUDE of the gyro ON THE GLOBE. Litton has delivered over 30,000 of these units since the 1990s and Every Single One of them was tested by verifying "Earth Rates".

Sure is a challenge to show definitive curvature huh?...
@ Edge Wyze "Sure is a challenge to show definitive curvature huh?" Actually it is not a challenge at all... Geodetic level survey over 1 mile, measure points every 50' along the mile, compare the elevation of these points with drops from a telescope at one end to a target at the other end, both telescope and target set at the same elevation, and you will get a perfect up and down 2" curvature. Takes 1/2 day to run with 3 people. (ex geodetic surveyor)
@@paulj1138
Yeah, but things in the distance get smaller. When you zoom in it offsets the measurements. That's why surveyors only measure two points equal distance from one center reference point. To compensate for "curvature" or in actuality it eliminates the error of angular resolution.
Same reason hunters have to "sight in" their rifle scope. So they know where the bullet hits at a certain distance, and so they can compensate for shorter & longer shots.
They'll sight it in at say 30 yards, get that on the bullseye, then move the target farther & closer to know how offset the shot will be. Doing this with their gun locked in to a special vice apparatus, & taking shots from the same reference point.
@ Edge Wyze. regarding diminishing size of objects (i.e. perspective).
Sorry you are wrong. I assume from your equi distant measuring points from a central reference point you are are referring to equal fore and backsights when leveling. The reason for doing that is to remove colimation errors. You can look up how colimation error is removed by doing close and distant sights in conjunction with balanced fore and back sights.
You should also research stadia measurement techniques which prove that 'level' does not rise or fall as a function of distance.
@@paulj1138
Dude, so at a football field every fifty feet there is curvature drop?
Nope, but the theodolite scope will still show said offset reading. Hmmm
@ Edge wyze
If I were to be pedantic (as surveyors are inclined to be ;) ) there is curvature every inch across the earth, but very small ;) - too small to be measured.
Think of it this way....
1) Use a geodetic level to measure the levels of every point 50' along a 1 mile length.
2) Pick any particular elevation that is workable at the location, and place a vertical marker at each 50' point, so the top of the marker is exactly at the chosen elevation (keep in mind the vertical markers will have different lengths because the elevation of the ground marker will vary - i.e. this is the real world where the mile long stretch is not perfectly flat)
3) If you want to go further, use some clear plastic tubing to make a water level as well, along the mile. You will see the water follows the same 'level' as the vertical markers.
4) Set up a telescope at one end and a target at the other with exactly the same elevation. If your vertical markers came up to the same elevation you will see the rise and fall over the mile.
Sure, it takes effort to do this. Also it is not numerically dramatic as simply measuring curvature drop over 1 mile (i.e. 8 inches per mile drop, vs 2 inches = 50mm rise and fall over 1 mile). I think I said 25mm in an earlier post - please ignore that one - I am busy today.
An advantage the rise and fall method does show immediately is the drop observed if using a theodolite is not related to 'perspective' at all.
So having been a Geodetic Surveyor who has observed this a lot in the past, especially when conducting dam wall surveillance surveys, I am not blowing smoke up your backside.
So my question for you is why is an up and down curve of 2" observed over 1 mile?
The earth must spin as the dizzy sensation you get when you bend down quickly and stand up is due to the increased centrifugal forces from the earths spin on your brain. but your experiment proves it just as well.
Feeling lightheaded after standing up quickly is not related to Earth's rotation. The increase in centrifugal acceleration over a few feet is physiologically insignificant; people at the poles feel the same effect even though there is no change in angular momentum for them. Furthermore, increasing centrifugal acceleration by standing up would decrease rather than increase weight, which would make it easier for the heart to maintain blood pressure in the brain. Consider: if you were a giant, 36000 km in height, then by standing up at the equator, your head would be in geostationary orbit, and your head's weight would be zero.
I think that affect is due to orthostatic hypertension, or postural hypertension.
Vibration and sound caused the rotation.
Care to elaborate? How does vibration cause rotation here?
The motor caused vibration and water reacts on vibration and caused also vibration - waves. If you have a drill, turn it on and put it on the table and it will rotate. Rotation causes sound. But maybe I am wrong and I did not watch or understood correctly.
During the run, the water is completely still. Any waves would be visible due to the reflection of the overhead light as you can see at 0:43 when I put my hand in the water.
I still don't understand what you mean about vibration causing rotation. I have a drill but there is no simple way to "turn it on" without holding it since I have to continuously squeeze the trigger. Could you link to a photo or video showing the setup you have in mind?
I can not fully judge your desing but where vibration is, is also rotation if the design allows it. You can block the trigger on your drill with a piece of paper.

This machine is deep in a mountain to avoid any distubing vibration that could influence the measurements. But I do not know what they measured, maybe satans shake on the pillars of the earth ? Who knows ;)
Maybe the scientists should have saved the millions for their gyro and just copied your design ;)
If vibration alone could cause rotation, that would violate conservation of angular momentum. If I put an electric toothbrush into a boat, do you predict that would rotate?
As for the ring lasers, the idea there is to measure the speed of the earth's rotation extremely precisely. In contrast, a gyrocompass like mine merely shows that the earth *is* rotating without providing much information about the speed.

Do you even know how to spell “experiment”?...
This is a terrible looking contraption. It's so totally goofy looking that it can't possibly be used to prove anything one way or another. In fact, it's simply laughable and rediculous. In effect, it's the OPPOSITE of "elegant" which is what a real nice universal 3 axis powered gyroscope would do to prove earth rotates or not. In fact, THIS video might be part of a larger "operation" (psyop_) to DIScredit any further look into a real elegant proof.

What gyro do you recommend?
Robertson Gyro-compass if you can afford it. And the earth does not rotate nor bend. yes its flat.
I think truewrldseeker meant "gyroscope" rather than "gyrocompass". There are plenty of UA-cam videos showing commercial gyrocompasses in action, so I don't know what value there would be in posting another.
Your title is "Gyrocompass showing effect of earth rotation" a real Gyrocompass does not show effect of earth rotation or curvature effect. It does not!. I do mean Gyrocompass not Gyroscope. google search "Robertson gyrocompass" for more information.
I agree that it has nothing to do with curvature. But rotation is essential. Quoting the Wikipedia article on gyrocompass: "A gyrocompass is a type of non-magnetic compass which is based on a fast-spinning disc and the rotation of the Earth". My video explains in detail how the Earth's rotation produces the observed gyrocompass movement. If the Earth is not rotating, then how do you explain the movement?
If anyone has a empirical scientific evidence of curvature or motion please provide it here
This video shows we live in a rotating frame of reference. You can build it yourself for less than $200 and it will work. As for curvature, search my channel for "horizon".
Wouldn't proving that an object is in orbit be proof enough? Especially if that object can be seen by people at ALL LATITUDES at DIFFERENT TIMES as it passes overhead? Anyone can go see the ISS pass overhead. There are two videos of it on my YT channel. Just by observing the times that the "object" rises above the horizon for some Observers while rising at later times for other observers? You can literally follow the ISS from different locations running north to south over the US and prove curvature that way. Give me your zip code or a nearby city and I'll tell you when to go see it yourself. My guess is that you REFUSE to even look.
Stuart Gray orbital mechanics requires the presumption of the R value.. it has never been independently verified.

You know about these devices but fail to mention their consistent drift procession, and are also unable to even fully define or prove your theories on what causes what you are experiencing. Rest assured there is no curvature or motion of earth. You will figure it out. Just don’t give up.

Stuart Gray besides what about all of the other apparent movements you believe in that this is not detecting? Why does it only detect the earth rotation? And if the atmosphere is locked with the earth how is it even able to detect it? You don’t realize your own belief system contradicts itself. All you have to do is pay attention to what you think
Nicholas Pitts - "you don’t know what light is, or the sun."
Actually I am an Electrical Engineer (the one's who expertise is the propagation of electromagnetic radiation - LIGHT).
I actually build, test, launch and operate spacecraft in earth orbit that use the Sun as a calibration source for the science instruments so I am fairly sure I know more about the sun than someone who has never graduated high school or taken an actual physics class.
"Your detector is simply measuring the movement of the sun."
No - these devices are used for guidance of missiles, fighter jets, and drones. They are FAR MORE then capable of reading earth's rotation.
However since earth's rotation is Perfectly predictable and measurable anywhere on the surface of the planet that we use it as a Measurement Standard when testing or calibrating our gyros. I have performed both the Gyo Performance of one of these units, and the pre-launch aliveness tests where we specifically HAVE TO measure earth rotation while the vehicle sits motionless or the Gyros are BROKEN.
"If the earth was moving we would be able to verify it"
We do verify it with optical observations of other objects in the sky, Gyro-scope based measurements DO detect earth rotation. It is the basis for the GYRO-COMPASS used by every world military and shipping company since about 1910. Look them up. Th Us military used gyro-compasses in artillery targeting scopes.
