"This train can't possibly be moving. If this train was moving, the posters at the front of the carriage would all be hitting me in the face at 500 mph." - a flerf, probably.

@@BogdanSassI'm going to use this move in my assassin job.
Yet they can't understand how it's the same for the planet.

@@BogdanSass yep...you can't throw anything in the direction u r going to.
Because the plane would be much faster than u r able to throw...so logical.
But if u throw a ball, in a train, and the train is just slightly slower/faster than u r able to throw...
best magic trick ever! xDD
The fact that I can drink a coffee on a train, proves that the train is stationary. Otherwise the drink should be smashed into my face at 120 mph (delicious, but scalding)
The doppler effect is pretty cool when you discover it as a small child. Of course some humans lacking the intelligence of an small child will be endlessly confounded by it.
Said pretty much this on a forum a week or so ago. Tumbleweeds. Not a single Flerf comment.
But I have the intelligence of a small child.
@@ImAmirusare you joking?
@rembrandt972ify i hope this was a grammar dig....loool..I was thinking the same thing...
@@ImAmirus
But the basic person isn't a scientist, and accepting the scientific consensus (which is implicitly what a basic person does) is more scientific than just disagreeing with everything even when proven wrong countless times.
They'll never understand conservation of momentum. Ever.
So many things flerfs don't understand can be boiled down to not understanding the conservation of momentum.
Lmao we'd at least need to GET to unit 2 in physics class for that. Relative motion is like the first WEEK of unit 1.
Even if they ever miraculously understood, the flerf reset occurs overnight and they'd be back to not understanding by morning!
Between CoM and net / relative motion, I don't know which confuses them more. How so many can fail to grasp such simple, intuitive concepts is far beyond me.
Don't forget flerfspective 😂
"I don't understand basic physics, therefore the globe is a lie!"
How often do we hear this argument ?
it looks flat so it must be flat lol
@@nostromza3433That's the thing, it doesn't even look flat. You can stare out over the horizon and see any semi big ship disappear below it but they've got excu- calculations to deny- explain away that as well
Flatters misunderstand this deliberately, since acknowledging it means they can no longer claim it doesn't make sense.
Acknowledging it would mean their old book is wrong.
I find that when I have to explain something to a flat earther im forced to explain it from the very basics. This helps me understand it better. The flat earthers aren’t listening.
You can give observational, geographical, rational, physical, theoretical, and even theological answers to debunk them, but nothing will work on them.
You know that the whole flat earth thing is a 4chan joke, like “ok sign” and charging iphone in microwave. If you ever find arguing with a self-proclaimed flat-earther - you are the joke buddy.
@@3rdHalf1 some are goofing and some are genuinely flat earth believers I never argue with them. I try to explain reality to them, not so much for them, but for me. Learning something from the very basics up helps me understand it better.
@@RossM3838 Stop arguing with flat-earthers. Embrace them and you will realise that globe heads are even more stupid. Because people who genuinely believe in flat earth are basing their belief on bible, not science.
@3rdHalf1 you are badly underestimating how mind-bogglingly stupid some people arem
Once again, flat earthers failing to understand relative velocity. I guess you could say they're pretty slow, relatively speaking.
Edit: Also, some flat earthers say stars are "luminaries" and that "space is fake", which they base off of their flawed observations(i.e. stars which are out of focus on the telescope). So I'd imagine they would claim that the red shift is made up as well.
Notice how the flattie refers to relative motion in respect to the waves and the radar yet fails to understand relative movement of the earths contained system.
Well, maybe they stopped developing after hearing nursery rhymes.
Twinkle, Twinkle, Little Star is a lie because stars aren't little and the twinkle is from the atmosphere instead of the star.
I'm surprised they're not hard at work arguing that chromatic aberration proves a flat Earth somehow.
according to them the moon is also a luminary. I did asked what the hell is a luminary? Not one can give a consistent answer. I also asked for explanation on lunar eclipse, again none of them can give consistent answer.
What I find profoundly depressing is people who think that the rest of our universe is just "lights in the sky"...

He's _projecting_ confidence. Not the psychological kind, it's like a stage whisper; you can't whisper on a stage because the audience wouldn't be able to hear you, so you have to actually make your voice loud enough for everyone to hear you while also suggesting that you're whispering. In cults, you put on a show of being absolutely confident, because that's what cults expect you to do.
Think about pyramid schemes. They hold meetings regularly for all the victims to get together and show off how "successful" they are. Everybody's face is contorted in a huge fake smile, people wear gold jewelry and giant overpriced watches and rent million-dollar cars to pretend they're rich at each other despite the fact that nobody there has any money. They're fooling each other. They know they personally are failures (or worse, "temporarily-inconvenienced millionaires"), but they see everyone else flashing bling and they think "wow this is super real and legitimate I better keep at it so I also will be rich!"
It's not even a question of whether they know it's all bullshit or not at this level. It's a show and they're acting their part. The victims being dumb enough to fall for it is just icing on the turd.
This was great! My grandson asked me this morning about the effect as a firetruck went speeding past. We watched this together.
He really made the jump from sound to light and said he finally understood Star Trek and red shifting.
@@Old52Guy wait, the jump to red-shift is understandable, but what was that about Star Trek? 🤔
I recognize that voice, not the first time he's lied about doppler radar. There's a reason we call him "Lie and Connive." The color of the returns on the precipitation products from doppler radar has NOTHING to do with the doppler effect. It's strictly based on INTENSITY of precipitation. He's built a strawman argument. His dishonesty knows no bounds.
I couldn’t tell if he was actually equating the colors on the radar with the amount of frequency shift… 🤦♂️
@@philvogelfilms He was being deceitful throughout his video. He was showing precipitation products instead of actual velocity products, he put up 2 different types doppler radars on the screen (again, precipitation products) claiming one was not doppler, and completely ignores conservation of momentum. In other words, he's lying, just like he lies when he says he was/is a meteorologist. He's not and never was a meteorologist. His claims prove that.
@@SkyDog59 what a mess! 😖
@@SkyDog59 #GLTF
@@philvogelfilmsThat was rather obvious when he said they were "green-shifted". Con artists do this all the time, I've found. The correct terminology is avoided in favor of a lie so that any potential victim clever enough to try to look it up on their own won't find real information. Super popular tactic with creationists calling everything "evolutionism" for example. Nobody will find anything about green-shifted frequencies, they'll find "Do you mean _blue-shifted?"_ and think "naw that's the globetard lie" and stay within the cult propaganda instead.
"Let's do a _quick drive-by_ debunk, using the _Doppler_ effect…" I heard what you did there.
We all did, except maybe the flerfs.
Do Flerfs never fly in airplanes? Acceleration and deceleration are felt. Speed is not.
They don't fly because they don't understand how planes work.
Or a train or car or any moving object.
Also airplanes don't have to fly 1,500 mph to fly west and -500 mph to fly east, because the air isn't moving 1,000 mph _relative to the earth._
And I don't have to stand against Mach 1.33 wind on the ground.
A better way to put it is that we cannot feel absolute speed, but we CAN feel a change of speed, like acceleration and deceleration, as well as vibration which is a rapid small change of speed in various directions.
@@chrisantoniou4366 Fun physics fact of the day: the rate of change of acceleration is _jerk._
I still don’t get why flat earthers can’t understand that our atmosphere is also rotating with us, making its (from our perspective) relatively motionless
It’s not that hard to understand people
Apparently it is even if I don't get why.
They assume that if it’s not touching the ground the object changes to a new frame of reference showing they no idea what a frame of reference is.
Why else say that there should massive winds at the equator?
Still to much for the typical flerf.
I think they don’t want to understand it. “I’m right and that’s that” mentality.
I see that whole “helicopter should be able to travel by hovering” meme BS too much.
2:40 the Doppler unit isn’t attached to the earth in his scenario? 🤦
Sure it is, that's why it's moving 700-1000 mph. It's the air and rain that isn't 'attached to the earth'. lol ;)
Someone's definitely detached from reality, that's for sure ...
Flat Earthers make my brain hurt... but I can't look away!
So true man...i get second hand derp and still can't stop..
Rich says "relative" as if it's an argument for him, when in reality it explains exactly why he's wrong. Not the first time he's debunked himself. Who remembers "there is no umbra/penumbra" based on the picture of a lamppost shadow when in the same frame was the clearly sharper shadow of the person taking the picture? 😂
oh my god, you're totally fucking right, the doppler effect would pose a huge problem to flat earthers- the sun doesn't redshift or blueshift as it passes through the day
It seems to be a reoccurring theme of them not being able to simply wrap their head around relative motion
Relative motion and absolute scale . . .
I've noticed that people defending nonsense keep using terms like "you've got a big problem" when trying to "debunk" reality, but I never hear science communicators or counter-apologists use that terminology when pointing out the actual problems with the flat earth model or religious claims. It's almost as if rhetoric is more important than factual arguments for some folks.
Notice also they will always talk about the speed of rotation of the earth in terms of its tangent velocity at the equator, i.e.1000 mph. They will never talk about the speed of the earth in the proper units which would be radians or degrees per hour. 15 degrees per hour or approximately 0.262 radians doesn't sound as dramatic as 1000 mph.
In these arguments, if the evidence supports your hypothesis, you argue literally; if the evidence does not support your hypothesis, you argue rhetorically.
The atheist/deist paradigm is the same. Proof v faith. Evidence v rhetoric.
I can feel the rotation of Earth... Oh, no sorry, I'm just drunk, carry on 😜🤣
I always find it so funny and so disheartening that these people took what was essentially a thought experiment, that 4chan (and other places) pushed as a joke, and just wholeheartedly dove headfirst into it. Like damn. Talk about getting lost in the sauce.
They're special ...
..., hockey helmet special ...
So this guy is very calmly and very confidently saying that you can't hear anyone to the west of you? Did I get that right?
If the world were a spinning globe, I guess is what he'd say.
Well, since i'm in Europe, he *_is_* to the west of me, so at least it's consistent that i wouldn't hear him say that. 😈
What exactly does he think the microwaves and radio waves are made of?
For those who don't know - it's photons.
Also called Light.
How fast does light move?
This whole "but the earth's rotation"...
Yeah it doesn't matter here.
It never matters. The speed of light is invariant between observers.
"You lack imagination."
If only that were all he's lacking.
Even *if* the radiowaves used by doppler radar have to 'fight' against the rotation of the earth when travelling west, those radiowaves travel at the speed of light, which is 675,000 times faster than earth's rotational velocity at the equator. The effect of 'fighting' against earth's rotation would be negligible at best, it's like comparing a single candle to a searchlight.
The radio waves would appear blue shifted going east and red shifted going west from a stationary observer's point of view. Within the Earth's frame of reference they aren't shifted at all. It's the same as a train making a steady sound when you're riding it but a changing sound as it passes by you.
@@wizardsuth This is how we measure stellar rotation velocity.
@@wizardsuth blueshifted/redshifted by HOW MUCH tho?
@@irrelevant_noobby a small but detectable amount, handheld radar guns have no problem using relatively tiny Doppler shifts to measure velocity on the scale of a few miles per hour
...and yet they can indeed detect just a few miles per hour differences in wind movement to identify tornadic rotations. Bad, bad argument.
If I forward jump on a moving train, how come I don’t jump super far due to the train moving or don’t jump too far because the train is moving in the same direction? Simple: relative motion.
True, I guess FE fans think if they were on an airplane, standing in the back of the airplane and jumped up, they would end up in the cockpit by the time they hit airplanes floor.
@@filippofittipaldi8050 It would blow their minds to consider that as you walk from the back to the front you are walking faster than the aircraft is flying relative to the ground.
conservation of momentum
this is the reason why you are not allowed to move about the cabin while the aircraft is ascending or descending, because that is when the aircraft is accelerating
Actually by.flat earth reasoning if I just stand on the ground and jump up the earth should pass under me and and should land in an entirely different place. If I am in New York I should be able to get to California by simply standing in one spot and just jumping again and again until the land under me is California.
So he believes in invisible energy (radar) but not in a very visible round earth? 😅
I would say that its because of evidence of their effects but we have it for both so yeah...
not just visible but measurable, they figured out the size and shape of the earth in, what, 200BC or something?
Most of them also believe in a magic man in the sky who supposedly created our world 6,000-10,000 years ago 🤦♂️
If it can justify his delusion about the Earth he believes it, if it proves he is deluded about the Earth he ignores it.
🤫
You'll ruin his wank ...
The moment this flerf mentioned anything about the direction of the doppler radar i knew it had to be about the rotation of the earth. Its like flerfs are intentionally misrepresenting earth rotation.
Oh wait, they have to
Note that we see the cosmic expansion with *galaxies* , not individual stars. Any stars we see are quite close within our galaxy, and the doppler shift shows its motion within the galaxy, which does not follow the distance trend.
3:50
A way to make it more clear. If your in a bus going 60 mph and you get up to walk to the back of the bus, you are not fighting against the bus going 60 mph in the other direction to go in that direction.
Apart from his wordiness, this poor guy was sounding sensible and well-informed until 2:15, when he started spouting utter rubbish. Has he ever travelled on a train or in a plane? Personal experience (so important to flat-earthers) is sufficient to tear his argument to pieces.

The first I've heard a flat Earther use the Doppler effect. Well, it's a new variation of not comprehending conservation of momentum.
This clown knows exactly how Doppler RADAR works, or at least he should considering that it's been explained to him at least 50 times by myself and many others who were either military or civilian RADAR operators and technicians. He is wilfully and deliberately misrepresenting it to keep the grift going a little bit longer.
Sheldon Cooper can explain more about the Doppler effect in 5 seconds, than a flat Earther could understand in their life.
that's because they have excellent science advisors on that show
sheldon cooper explained it by purely by wearing a halloween costume.
@@KenLordneeeeeeeeee……OWWWWWWWwwwwwwwwww
@@KenLord His costume didn't really remind me of it. I'm thinking more of how he explained his costume to Penny, and that one word "relative" that Flat Earthers cannot comprehend.
Flat Earthers will deny their mothers existed if it meant 'getting one over globe believers'.
Why does he think the sound would be moving away, or towards, the Doppler unit due to the rotation of the earth? The Doppler unit would be moving just as fast in the same direction. He *just* got done describing how the Doppler Effect works; he *said* the word "relative" several times. Was he not paying attention to the words that he was reading as he read them?
Bingo!
That's the thing when you're just parroting stuff, like he does. You don't have to know what you're talking about.

Man, I watched your videos pre-covid but stopped for some reason, can't really say why, and seeing this recommended to me hit me with a wave of nostalgia. Time to binge everything I've missed.
I once thought like that, then I went to high school. I think this guy didn't pay attention in school. Thank you Profession Stick. These guys can't understand that everything in the Earth moves along with the planet.
Radio waves move at 300,000kps. At the equator, the Earth spins at 1600kph or 0.444kps. Even if we were to correct the Doppler signal to take the Earth rotation into account, it would merely be a rounding error.
I just think it's funny how they all think 1000mph is so unbelievably fast...
Anything with more than 2 digits is a big number to a flerf.
For them, 1000 miles per hour is probably already ludicrous speed, which we all know to be way faster than light speed. Maybe that's why some flat earthers claim some really weird "laws of perspective" - it's because in their world, the speed of light is so low.

I just saw the Video-Preview-Image and thought: WOW this is a genius flerf-debunk!!! Thanks for posting!
As someone who has worked with the math involved in RADAR technology, it is very much not a "simple" calculation if you want to see anything more than like 1km away without having to rely on a nuclear reactor as a power source.
Also, the math is really fascinating especially with how far and detailed it can see
I'm imagining brute-forcing it with a massive radar transmitter which heats the air so hard it causes clouds to form and fries birds.
Sorry I may have missed something here, but can you explain just why you think that you would need the power output of a nuclear reactor to provide enough power to get a RADAR range of more than 1km?
@@thearmouredpenguin7148 you gotta interpret the results you get back, and with any sort of not comically insane radar setup the image received requires some analysis in order to make sense of it.
@@thearmouredpenguin7148 Probably the inverse square law combined with attenuation through both the air and any precipitation? I'm not an expert, but the weather radars I've used mounted on jets have a threshold at which they stop receiving returns behind thicker precipitation and just draw a big colorful danger arc.
I suppose the math has to do with only using short pulses while the radar sweeps. The calculations allow you to use the actual transmitter for such a low percentage of surveillance time that, even running a nearly gigawatt output, it doesn't need much energy throughout the day.
@@CookiesRiotbirds aren't real. All birds are surveillance drones.
James Webb Telescope recently confirmed the expanding universe as well.
This would assume that they understand how doppler even works. They like to use it in a debunk but if you use it against them then suddenly doppler will be fake and not real.
That was satisfying to watch and hear. Thanks.
3.45 the simple explanation is that radar antena is also moving with earth surface
As soon as the flerf started in on how the doppler stations don't adjust for the direction I knew this would be a "1000 mph" argument. Too bad the radar station is not actually stationary and is moving along with the Earth's rotation as is the atmosphere.
Nice shot of where I live on the doppler weather map shown in your video Professor 😊
This question was already answered in Prof. Dave's magnum opus video.
"Lets get back on that moving truck"
Another thing about weather radars.. the domes are spread out across the nation/globe.. they're spread out because the signal constantly rises as it gets further from the dome. Why? Because the earth is round. There are some weather scenarios where it could cause the signal to rise faster, or, fall and hit the earth surface. But in a steady, stable atmosphere, the signal rises as it travels further distance.
If the earth was flat, we wouldn't need near as many radar domes to get the coverage we currently have.
When it comes to Flerfer's inability to comprehend the size of Terra in regards to the 1000 mph rotation, I am reminded of Father Ted explaining Cows to Father Duggle.
Professor Stick, to help make relative velocity be more understandable, even if they deny it. You can walk to the back of a train just fine, even though it's going way faster than you are walking backwards.
It's like being in a plane, how do they not understand this fact. Just take a radar gun on to a plane with you and see if it messes up trying to read things while in flight. Hint, it won't.
I actually did not expect FLERFS to get it wrong in THIS way..... what the hell....
The Doppler effect also proves that the earth is revolving around the sun. We can see the speed difference in the Doppler shifting of light from nearby stars every 6 months, as the earth changes its orbital direction around the sun.
"We can see.."?
We can *measure*. Maybe a minor point, but when you're dealing flat earthers..
@@drlegendre I'll compromise with you and say "observe".
Flerf-arguments always boil down to "big number scary". The earth rotates 15 degrees per hour and everything on or very near the surface moves at practically the same speed.
It's like walking the aisle in an aircraft flying along at over 500 mph. Can you walk that fast? of course not, but walking the aisle in a plane toward the front, you're walking faster than the plane is travelling?
imagine you are inside your car and going about 40 mph, and by chance you have a water cup on your cup holder or smt very wierd how the water inside it is also going 40 mph.
i use this explanation for when ppl don't understand the earth's rotation, its very simplified but it gets the message trough, sometimes......
l use the Concorde which flew faster than Earth's rotation at the equator.
Easiest way to explain the whole rotation thing is this:
If you stand up on a moving bus you are still moving with it and not even notice it.
You *will* notice it if I hit the brakes.
Omg... My eys rolled back when I guessed where he was going with that... Flerfs really like to ignore conservation of momentum... smh .
3:00 so by that same logic ... everytime we walk out side its in to a RAGING 1000MPH wind 😂
Thanks for the video :)
It's not the.lack of understanding science, it's an overload of (religious) dogma that confirms an accepted narrative
I work as senior software engineer in a company making maritime navigation electronics. The earth rotates. We've checked.
Oh, the poor poor flerfs... I do wonder how they manage to breath without assistance ?
Professor Stick, lol, I'm not sure flerfers will ever understand the atmosphere moves with the planet!¹👍💙💖💙🥰✌
i swear! I thought he's say something akin to "Why morning sky looks blue and evening sky looks red? COZ SUN BE MOVIN TO AND AWAY FROM U, LREAN THE DOPLER FX KID!" kind of stuff xD
Funfact, i work/help on a device to calibrate weather radar.
It's ground based radar. The antenna is moving with the globe!
Neat, I called the flaw in their argument before they even made it. A lack of understanding of relative velocity and fluid dynamics
If the Earth was flat, the sun would be red and blue shifting by varying amounts throughout the day.
Why don't they understand that the atmosphere moves with the rotation? Why do they use the "1000mph" when 15 degress per hour is better suited? Why when this is pointed out and explained time and time again, do they just ignore it? The mind boggles!
To answer all your questions...."gotta lie to flerf" comes to mind.
Exactly. The hour hand of the clock rotates twice as fast as the earth.
The only thing that I took from this video is that Half-Life: Blue Shift was named after an actual thing and not just some shit Valve came up with lmao. Love the good content and keep it up
I've decided that the weather is fake. I'm throwing away my umbrella and snow shovel.
That is a flat earther trusting the Doppler effect. So how do they explain the Doppler shift of International Space Station signals matching an orbital speed of 17,100 mph?
Me, starting this video: "This guy doesn't understand that the atmosphere gets dragged along with the surface, that's going to be his argument."
Me, at about 3 minutes in: "I effin called it."
Working for a weather service I'd also like to point out that the images he's using are _not_ even Doppler images, but simple reflectivity (i.e. intensity of precipitation).
"This thing I don't understand disproves this thing I don't believe in..." - Every Flat Earther Ever
Interesting video.
conservation of momentum. Enough said.
3:21 only mostly correct, never forget the Coriolis Effect which is a phantom force caused by the differential linear velocities of things at different latitudes, which behaves very differently on a spinning globe versus a spinning disk (if they think the earth spins at all)
I face palmed so hard I actually saw the Doppler effect walk through next door’s garden.
The earth spins, nay whirls at 15 degrees/hour, achieving 1 complete rotation in a 24 hour day. Zoom!
The storm is attached to the Earth, the radar is attached to the Earth, they both inherit the Earth's speed. If the Earth is spinning 1000mph, then the radar's velocity is 1000mph east. If a storm is approach from the west, towards you, it's going 1,020mph east. The "relative" difference between radar and storm is 20mph east. If you wanted to grossly oversimplify. If you wanted to simplify even more, the radar can't see over the horizon, oops, that's awkward. If the Earth were flat, one tall radar site would be able to monitor all storms around the Earth simultaneously. Guess he forgot that part...
How to explain it: Doplar detects shifts in motion RELATIVE to the station. Since the radar and atmosphere are moving along with the earth at the same rate, this means all the rotational motion is equal in all items relative to the radar, so no shift due to the earth's rotation is detected by the radar.
Omg flerfers say the dumbest things. As he was talking Iknew exactly where it was going, and I also realised that he had said the "relative to" bit and just shook my head.
It's always the same confusion between relative and absolute (rotational) speeds. The conceptual difference between them is trivial; are they just pretending they don't understand?
Short version: FLERF demonstrates he doesn't understand what an "inertial reference frame" is.
Even Galileo figured this out.
Every time I hear that ''spinning ball at a 1000km/h'' argument, I wish I could get the moron in my car, drive at 60km/h and have him throw a ball in the air. Then ask him; did the ball hit your face? No? How come? We're moving at 60km/h!
Not to mention that using linear velocity to a rotation is like using a ruler to weight yourself. Again, I wish I could have the flatard stand before me, having them say how long it take for the Earth to allegedly make one full rotation (yeah, what is called a day: 24 hours) and then have them spin around at that exact speed. What a dizzying ride!
At the end of the day, they just don’t understand Conservation of Momentum.
Or net/relative motion. They even demonstrate their confusion when they make that crazy-spinning-hands gesture.
There is a common trend that these people don’t understand the earth is a closed system
I guess those guys have never thrown a tennis ball while standing on a moving train.
Well neither have I, but that's beyond the point.
What? Mr. Thrive and Survive has production values now?! But he was a leading light in the world of Microsoft Paint!
The earth’s “spin” is a mystery to flerfs. They always depict the “spin” as a small ball rotating at a ridiculous rate, and therefore come up with very silly ideas about how we should feel that “spin”, or how we should be flung off the surface due to centrifugal force.
1000 miles per hour “spin” is only one full rotation per 24 hours…because the Earth is really, really MASSIVE!
That galaxy red shift topic brought up a question I haven't thought of before: How do flat earthers explain that we see a sphere of stars above us and not just the hemisphere you'd expect from a flat earth?
Don't hurt your brain too much. Some think stars aren't real. Some say Earth can't be a globe because we see the same stars all the time. They have "explanations" and it will just give you a headache.
I even asked why planets are spherical.. and I was banned from that Flat Earth discord after they told me they aren't real lmao.
@@Gandhi_Physique Ah. Thanks for the advice.
The problem is entirely within the head of that guy. The Doppler effect is the same for an object moving toward an observer and for an observer moving toward the object. It's depends entirely on the RELATIVE motion between the observer and the object, not upon any «absolute» movement.
We can measure the red-blue shift of light from stars from looking at them when they are to the East and when they are to the West, measuring the tangential velocity of the observer on the surface of the Earth. We can also measure the difference over a 6 month difference, thus, measuring Earth's orbital velocity.
