It is frustrating how you don't get more views. I find the content very interesting and well edited, and i am an engineering student, meaning i basically know or have already read about most of this stuff. Yet, seeing it from the perspective of someone who does not really know how these things work, it must be fascinating! I say the number of views is frustrating is because there are teenagers talking about ther day in the gym and have millions of viewers, and SmarterEveryDay really contributes into a very big issue by educating more people onto embracing science. Did you know there are only about 7000 astrophysicists in the world?! (I am rounding up) I share all your videos anyway :).
Thanks for the advice, it means alot to me. I feel like my strengths lean towards physics and aero/astronautics so i wish to pursue perhaps astrophysics and maybe something like mechanical engineering or astronautics but as i further my education ill take it as it comes and see where i end up i guess.
Archie Lucas hahaha, whatever happens i don't really care. I don't do what i do for myself, i have the lowest appreciation of myself. I know that, no matter how much money i make, no matter how many "Dr" titles i get, or how successful i am in another perspective, as long as i don't have a big happy healthy family, i have failed. That is just how i am. Lets not forget what the important things are, it is easy to lose yourself in this crazy world, make sure you have a home to go back to.
+Arjan Kasapi Go for it man, different people just have different mindsets and so whatever makes you successful in your mind, work out a means of achieving it and sustaining it then go about doing it. I don't want to get to nosey and personal on a UA-cam comment so I'll stop there but just totally do what you enjoy and channel that into something you would call success by means of many many smaller achievements. Look up Dave Brailsford ? I think and his “aggregation of marginal gains.” towards British cycling. Sorry, I'm rambling but all im trying to say it do what makes you happy, surly thats a significant stepping stone to 'success' then go forth and work on aspiring to a little something else which would get you closer to being ultimately 'successful'
Because NASA and real life are two diff things. You will be building real things in the real world with real people's lives at stake. NASA makes images and spends our money on God knows what. Watch the Mars Rover lander presentation videos. It's laughable at best!
That CMG was actually from Skylab. Note the date on the data plate. My Grandfather worked on Skylab so it was really awesome to be able to put my hands on it.
Defiant Oli if you imagine even while you are floating you are able to move your arms and legs. You can begin to understand that unless held in position you will be able to move, spin, turn. By adjusting where the weight is or "throwing weight" in a direction.
We need more on reaction wheels. It looks like a lot of people don't fully understand this who watched the video, including me. For instance the wheel doesn't look like it has a way to increase its moment of inertia on that flywheel (like the cat extending its legs). Perhaps the flywheels axle isn't the axis that is used, but the gyro causes the secondary axis to have a higher moment of inertia. I'm kinda lost on this, I have no formal education in physics. I would really like another video on this, You already have the fundamentals laid out (cat video, gyro videos, this video). Great video though!
Prometheus I can only assume that there are electric motors used to keep the flywheels spinning. This would allow them to speed up and slow down these wheels so that they can manoeuvre the satellites
Seems like all they need are reaction wheels, not rocket fuel. Shut the spinning off when one hits a blockage and then torque it back the other direction, then spin back up for that increased torque of moving against rotational inertia.
Zé Bianchi a gyro , its like a spinning top or a spinning bike wheel and it wants to stay upright. force from spinning things. having two axis for control. physics is weird, im just a layman.
Go to the airport, a large one, when there aren't many people there. Ride one of the people mover belts. Walk forward while the belt is moving under you. Stop. Then turn around and walk backwards. That's momentum and inertia.
I understand how reaction wheels, torque rods, and gyroscopes work. But if I was some one watching this video to try to learn about the concept, I'd still be confused. The video did a poor job of explaining how they actually work -- particularly with demonstrations of the technology. (Improvised or otherwise.) I vote for an updated video.
2 things i wanna thank you for: 1, shell in the pit. seriously, amazing music. i love watching your videos just cuz you have great sounds beyond what you're explaining. 2, giving me a REAL reason why the space shuttle was abandoned. i don't understand why they couldn't update it, but it makes somewhat sense that they just need SOMEthing new to progress from where they were. outdated hardware makes sense to a point. i've seen some new ideas for shuttles and am excited to see what happens.
I don't get it... I always thought cats can rotate external force free because they bend their back (out of it's own body center of gravity) turn "inside out" (not really inside out, but I don't know how to explain that rotary motion). Does anybody know what I mean? / Agree?
They use similar physics to figure skaters. They extend their arms to slow angular momentum. Cats extend their feet, and since they have two sets of feet to do this with they can have one set have high angular inertia (extended) and use it to move the other low-inertia one into position, and then switch the roles. One way they can use wheels to flip themselves is storing angular momentum in the wheels, so they're spinning while the telescope isnt, and then taking it out to spin then putting it back in to stop. However they cant just have one for each axis cause heavy spinning wheels cause gyroscopic precession when you try to rotate it using something else like another wheel Might have gone abit on a rant off-topic, saying it helped me understand it though
I'm also having trouble understanding. I thought Destin said that the "path" was the key? So are you saying that if they rotate legs while extended they can change the 'path' of retracting the legs to use it like an outside force?
+DDG aaaahahahaha,good one...but really,it's in orbit, for it to be "on" orbit the word "orbit" would have to mean a certain solid object that things can be placed ON,and orbit doesn't mean that,so it's IN orbit.
Thomas Hardy I agree. I don't think I worded my original comment without ambiguity. I have always used "in orbit", so I was just curious if others say "on orbit". These little linguistic anomalies interest me. Because I'm clearly bored :P
"Great are the works of the Lord, studied by all who delight in them." Love your verses at the end Destin, I could not agree more! I am a chemistry major and I find it so exciting to be able to do science and get a peek into the beauty of creation. Keep making videos! I love them!
Here is a idea for a video, explain counter steering on a motorcycle. The reason I say is it a subject that has been covered so many times (in the moto-vlogging community, I am a vlogger) but I have never seen the science behind it! Been watching your videos for quite some time now! Great stuff!
Destin, this was awesome... this is partly what I am currently earning my engineering degree for is to work on systems like this in satellites. This got me super ready to finish my degree asap! Love your videos, thank you again for all you do. PS... best model of Hubble ever, lol!
You didn't age a year since this video. How do you do it, Destin? Also really impressive that the JWST takes over 10 years to make... by the time of launch the technology is a bit obsolete.
I'm lost on a particular point he made. He says that the ball doesn't return to the initial state when it is moved along a different path, and concludes that the path determines the state of the system. Then he says, "so just like the ball never slips, angular momentum in cats and spaceships never changes." What does he mean by "slips?" And how is this connected with angular momentum?
Slipping mean when the ball moves without rolling (rotating) but rather like a block which slides. Slipping messes up the rotational motion because of the added friction and reduces angular momentum, I believe.
Interesting video! This is an invitation to see an artist theory on the physics of light and time! This theory is based on just two postulates 1. Is that the quantum wave particle function Ψ or probability function represents the forward passage of time itself 2. Is that Heisenberg’s Uncertainty Principle ∆×∆p×≥h/4π that is formed by the w-function is the same uncertainty we have with any future event within our own ref-frame that we can interact with turning the possible into the actual!
my father worked on the Hubble space telescope he told me a story of the lenses would get foggy after they put it in space because the technician who put it in had cologne on and it got on the mirror.
I just want to thank you for providing great content. I am always looking forward to your uploads, and enjoy watching your videos while I sit at my desk eating my lunch, a great break to my workday. Keep it up Destin, as long as you keep making Smarter Every Day, I'll keep watching.
Hey Destin, please let your dad know that they are WAY over budget, over a year late, and he now owes you money for your children's education. 😂😂😂 Only by a billion dollars 😂😂
Destin, your explanation of nonholonomic systems was superb! Seriously, its the best explanation I can find on UA-cam. Wish I found this video a few months earlier when I had a project involving this concept!
When you said he's your dad followed by "you see this thing is designed to operate at 45 degrees kelvin" I was expecting you to say "and that's just how cool he is".
+Abon Bon I would guess it's because it's Federal building. I.e. they have a requirment that the building needs to be ADA (Americans with Disabilities Act) accessible. Meaning, for anyone working there or visiting, the building needs to have ramps for wheelchairs and braille if the person is visually impaired, etc. ;)
YOUR FATHER IS WORKING ON JAMES WEBB?! Mind blown.... I love your videos, and I love space. The James Webb telescope makes me giggle like a school girl with excitement.... CANT WAIT till they launch that thing.
6:54 its obviously a show room for nosy people, i mean i understand about the hardware needed to be the same of the good ole boy satellite, with NASA's budget, you would expect a different LCD motherflipping monitors or mouse/keyboard, i mean come ON, who you fooling NASA?
3:35 HEY GIVE ME BACK MY CAT!!! lol The resemblance is uncanny =3 One could emulate the use of torque rods, If one used three (nested/concentric) perpendicular gyroscopes in an assembly, along with commutators to maintain their speed. Instead of altering their speed, you would just have to mechanically spin all, or part of the gyroscope assembly in order to re-orient the vessel. While avoiding lock ups. It would have a ton of moving parts, but it would run solely on electricity.
yes, i mean, you probarbly misunderstood me, i was careful to say that MOST of his books are about evolutionary biology. The god delusion is the exception, as its almost entirely about religion. But what about: the greatest show on earth, the extended phenotype, the blind watchmaker, the selfish gene, climbing mount improbable, the ancestors tale? and i think sometimes ridicule can be appropriate, laughter helps against fear, and religion often uses fear: fear of judgement, hell and damnation.
(2) I don't rely on unicorn based arguments, no matter how many times you say I do, for my null position in relation to the existence of a deity. (3) I don't conclude "no unicorns, therefore no god", no matter how many times you say I do. (4) I don't go out of my way to assert the non-existence of unicorns; the null position requires near-zero activity although I am active a-unicornist in the sense that my mind is not dormant.
I've pointed out like 15 over the course of this discussion and you've ignored everyone. In fact, you've made the same generalisations of my supposed arguments when I've repeatedly said that those don't accurately represent my arguments. Go back, read what I've said, and then write a proper counter-argument. Note several things: (1) unicorn-based line of reasoning is far from my only argument, you just claim it is because that's the only one we've focused on.
"You used unicorns and fairies to justify your active disbelief in all gods" - which, as you should know, doesn't represent the totality of my arguments for believing that a belief in a theistic deity is irrational. "You do go out of your way to assert the non existence of unicorns" - no, I don't. You know full well that I stated I don't go out of my way. "You therefore actively claim a-unicornism, as well as atheism" - No, I don't. I reject your notion (but not mine) of active a-unicornism.
"But you have already admitted that you are an active a-unicornist." - again, NO I did not. You think there is some strange 'active belief' that isn't distinguishable from a presupposed rejection; i.e. a null presupposition. You then give this made up attribute of yours to your arguing counter-part and attack them for holding it when they don't. "So your only line of argument actually is to equate all gods to unicorns" - AGAIN, NO IT IS NOT. Show me where I said that.
I don't see why you are trying to trip people up when it comes to the word "active" and then lambaste them for giving them that attribute. I'm an active a-unicornist in the sense that there is no evidence for their existence so I reject any claim that they exist. I take the null position because that's what should be done in most instances when it comes to claims. Not sure if you know what a null hypothesis is, if not, google. In statistics, one does not presuppose the alternative hypothesis.
"So you chose to base your active assertion of disbelief in all gods based on the absence of evidence" - What's wrong with that? As kossmikham stated, you don't believe in unicorns for the same reason he doesn't believe in a god; absence of evidence. Simple. Don't forget that the claim of a deity is what requires the evidence. The null hypothesis (no god) isn't rejected until evidence supports the alternative hypothesis (god exists). Until that evidence is available, we stick with the null.
just take a look at the books richard dawkins published, and you will see that you are wrong. Most of his books are about evolutionary biology. that includes his most recent one, its about the evidence for evolution. and he got his ph.d. and his professorship for evolutionary biology. most of what he did for TV is also about evolutionary biology.

its obviously a show room for nosy people, i mean i understand about the hardware needed to be the same of the good ole boy satellite, with NASA's budget, you would expect a different LCD motherflipping monitors or mouse/keyboard, i mean come ON, who you fooling NASA?
its unnecessary to put a bigger more clear monitor that coast $70 like an LCD monitor?
seriously, dude this is drama.
3:35 HEY GIVE ME BACK MY CAT!!!
lol The resemblance is uncanny =3
One could emulate the use of torque rods, If one used three (nested/concentric) perpendicular gyroscopes in an assembly, along with commutators to maintain their speed.
Instead of altering their speed, you would just have to mechanically spin all, or part of the gyroscope assembly in order to re-orient the vessel. While avoiding lock ups.
It would have a ton of moving parts, but it would run solely on electricity.
yes, i mean, you probarbly misunderstood me, i was careful to say that MOST of his books are about evolutionary biology. The god delusion is the exception, as its almost entirely about religion. But what about: the greatest show on earth, the extended phenotype, the blind watchmaker, the selfish gene, climbing mount improbable, the ancestors tale?
and i think sometimes ridicule can be appropriate, laughter helps against fear, and religion often uses fear: fear of judgement, hell and damnation.
(2) I don't rely on unicorn based arguments, no matter how many times you say I do, for my null position in relation to the existence of a deity. (3) I don't conclude "no unicorns, therefore no god", no matter how many times you say I do. (4) I don't go out of my way to assert the non-existence of unicorns; the null position requires near-zero activity although I am active a-unicornist in the sense that my mind is not dormant.
I've pointed out like 15 over the course of this discussion and you've ignored everyone. In fact, you've made the same generalisations of my supposed arguments when I've repeatedly said that those don't accurately represent my arguments. Go back, read what I've said, and then write a proper counter-argument. Note several things: (1) unicorn-based line of reasoning is far from my only argument, you just claim it is because that's the only one we've focused on.
"You used unicorns and fairies to justify your active disbelief in all gods" - which, as you should know, doesn't represent the totality of my arguments for believing that a belief in a theistic deity is irrational. "You do go out of your way to assert the non existence of unicorns" - no, I don't. You know full well that I stated I don't go out of my way. "You therefore actively claim a-unicornism, as well as atheism" - No, I don't. I reject your notion (but not mine) of active a-unicornism.
"But you have already admitted that you are an active a-unicornist." - again, NO I did not. You think there is some strange 'active belief' that isn't distinguishable from a presupposed rejection; i.e. a null presupposition. You then give this made up attribute of yours to your arguing counter-part and attack them for holding it when they don't.
"So your only line of argument actually is to equate all gods to unicorns" - AGAIN, NO IT IS NOT. Show me where I said that.
I don't see why you are trying to trip people up when it comes to the word "active" and then lambaste them for giving them that attribute. I'm an active a-unicornist in the sense that there is no evidence for their existence so I reject any claim that they exist.
I take the null position because that's what should be done in most instances when it comes to claims. Not sure if you know what a null hypothesis is, if not, google. In statistics, one does not presuppose the alternative hypothesis.
"So you chose to base your active assertion of disbelief in all gods based on the absence of evidence" - What's wrong with that? As kossmikham stated, you don't believe in unicorns for the same reason he doesn't believe in a god; absence of evidence. Simple. Don't forget that the claim of a deity is what requires the evidence. The null hypothesis (no god) isn't rejected until evidence supports the alternative hypothesis (god exists). Until that evidence is available, we stick with the null.
just take a look at the books richard dawkins published, and you will see that you are wrong. Most of his books are about evolutionary biology. that includes his most recent one, its about the evidence for evolution. and he got his ph.d. and his professorship for evolutionary biology. most of what he did for TV is also about evolutionary biology.
