How FOUCAULT PENDULUM Works and Proves Earth is a Round SPINNING Sphere

Ғылым және технология

Earth’s roundness is obvious to any who care to observe, but the fact that Earth spins on its axis is not as apparent. French physicist Leon Foucault wanted to remedy this situation so that the masses could experience Earth’s rotation with their own eyes. To do so, he built a 67 meter long pendulum in the Pantheon in Paris, France. The point being that the pendulum not only bobs back and forth but also rotates as well. This phenomenon is of course due to the rotation of our planet. What’s happening is that, because the pendulum bobs and rotates regardless of our planet's rotation, it remains fixed while Earth beneath it spins. So to anyone who’s attached to and therefore spinning with our planet, it’s the pendulum that rotates and not Earth. So through this simple experiment we can experience indirectly the rotation of our planet. This phenomenon is easy to visualize when we are at the poles. But not as easy in between the poles, because in between the poles, our pendulum is flung around Earths axis. So it’s not clear what “fixed” means in this context. In this video we help you visualize why the pendulum spins in between the poles using visual aids. Circles, cones, lines to be exact. We also show you how to derive the equation that predicts how long it takes for the Foucault Pendulum to rotate at any given latitude. A little bit of math but totally worth it.
If your interested here's an in depth paper on the subject: A simple geometric model for visualizing the motion of a Foucault pendulum, John B. Hart, Raymond E. Miller, and Robert L. Mills, American Journal of Physics 55, 67 (1987)

    I am copy pasting my comment from above so that you see that this isn’t a definitive explanation for how this pendulum works. See below 👇: Yikes-the Foucault Pendulum strikes again! This is NOT evidence that the earth rotates. Sorry folks. This USED to be considered a reliable “proof” that the earth rotates but the “general principle of relativity” changed all that. That’s because the principle allowed for both a “geometric” equivalence AND a “dynamic” equivalence. In other words, there are not one ☝️ but TWO ✌️ explanations for the pendulum’s behavior: 1. The pendulum is behaving this way because the floor is turning with the rotating Earth because the Earth’s gravity is pulling on the floor but NOT pulling enough on the free-floating pendulum. OR-and this is the part no one realizes… 2. The fixed Earth’s gravity will hold the floor still, but the rotating universe will create the centrifugal and Coriolis forces that pull the free-floating pendulum so that it turns against the fixed floor held to the fixed Earth. This is why Einstein wrote: Albert Einstein: ”…to the question whether or not the motion of the Earth in space can be made perceptible in terrestrial experiments. We have already remarked that all attempts of this nature led to a negative result.” Source: * Relativity - The Special and General Theory (1916), Part I: The Special Theory of Relativity, Experience and the Special Theory of Relativity So while it is a very nice pendulum indeed-it doesn’t actually “prove” anything.

That does seem logical, actually there's no logic in that at all.”_ That's because you lack the intelligence and reasoning skills to think logically. Which is proven when Flerfs claim their sun is a 51.5 km (32 mi) diameter object (you can't even agree on what shape it is: spherical/disc (thickness?)/flashlight/WTF?), circling over the FE at 4'828 km (3'000 mi) altitude (give or take[¹]), it can appear to set (fall; drop) below the plane of the horizon, when, from the furthest vantage point anyone might be able to observe it on the FE (theoretically at least, when _zenith_ to the Tropic of Capricorn it is observed in opposition from the South “Pole” Rim), its elevation would still be 10° above the horizon! THAT is not an insignificant elevation angle. As seen from the North Pole, it would NEVER fall below 31° elevation, ABOVE the horizon when _zenith_ over the Tropic of Capricorn; and its elevation would never fall below 45.7° above the horizon when it's _zenith_ over the Tropic of Cancer. And yet you argue there's “logic” to the assertion it can “appear” to fall below the horizon, while 31°-45° above it! 🤔 Please do elucidate us, ol' wise one. [¹] Samuel B Rowbotham (Parallax) claims it's _“not more than four thousand miles”_ in altitude, but his calculations suggest it's much lower than even 3'000 miles, if you do the trigonometry of his calculated angles and the distance between his observation locations in England-which he claimed were on the same meridian (they weren't)-as published in his book _Zetetic Astronomy-Earth Not a Globe!_ 🤔 Where's the “logic” in that absurd nonsense?!? Then there's the lack of a _“logical”_ explanation as to why we don't have hurricane force winds (or hear sonic booms) _every day_ caused by a 51.5 km diameter object (the sun) passing overhead, speeding through the atmosphere[²] at: Mach 1.57 (1'940 km/h or 1'206 mph) when _zenith_ to the Tropic of Cancer; at Mach 2.12 (2'623 km/h or 1'630 mph) when _zenith_ to the Equator; Mach 2.68 (3'306 km/h or 2'055 mph) when _zenith_ to the Tropic of Capricorn; and/or all Mach speeds in between as it moves between latitudes over the course of the seasons. [²] The entire volume of space between the FE surface and the _impenetrable_ “firmament dome” is filled with an inert gas (atmosphere) under pressure (~1 bar; 1'013 hPa; or 14.696 psi), which according to you “logical” dullards, keeps us all pressed firmly down upon the Earth's surface. (NOTE: Without gravity, _there is_ no _atmospheric pressure gradient_ with an increase in altitude; no _atmospheric pressure gradient_ means no _“lensing effect”_ in the atmosphere, since lensing occurs only when light passes through transparent mediums of differing densities.) You more-ons can't even agree on what the radius of the Equator is, for that matter-🤔 is it 6'378 km (3'963 mi) as measured on the globe Earth, or is it 10'019 km (6'225 mi) as measured by the arc segment distance between the North Pole and the Equator (on a globe Earth)?!? (The elevation and speed of the moving sun provided above are based upon the latter equatorial radius.) I could go one, but I honestly don't have the time or the crayons to explain the rest to you. When brain-dead and shamelessly stupid Flerfs claim to have a monopoly on logic, all I can think of is: _‘how Dunning-Kruger of you’._ *Dunning-Kruger:* _'Those who know the_ *least* _think they know the_ *most.'* *Tuteur Corollary:* _'If they don't understand it, they think it's a plot to harm them.'_

    ​@@lightninlad Using classical mechanics, you can predict the precession rate of the pendulum at any latitude. Measuring the precession rate at a few latitudes would be enough to find the rate of rotation of the Earth and showing that it is also round (spoiler alert: this can be done and will verify the predictions). Hence, even if any centrifugal force was applied on the Earth from rotation of a larger ensemble, this has a much smaller (insisting on the "much" here) effect on a pendulum on Earth than Earth's rotation. Also, the quote you used from Einstein is (1) not complete and (2) incorrect. (1) Einstein finished this quote with: "though the Earth is revolving around the Sun." (2) Just before where you start your quote, Einstein was writing about the Michelson's inferometer, an optical instrument. You quoted Einstein as saying "terrestrial experiments" when in fact, Einstein used the word "optical", referring to the inferometer and other optical experiments.

Additionally, no-Einstein knew that all of the observations regarding the pendulum would be exactly the same if the earth wasn’t moving. You would get the exact same measurements. That’s what relativity means. The pendulum IS a terrestrial experiment. It proves nothing.

    @@frankdrebin2343 " how can there be a "fixed point" that doesn't rotate if the building is rotating" The fixed point as you call it is in effect a free swivel, a universal joint which allows the pendulum to rotate freely around its fixing point as it swings. You can set the pendulum swinging in any axis you want. You could set the pendulum swinging in a fashion that it would be swinging in a circular pattern. Looking top down at the pendulum, you can set to swing at any point of 360 degrees. If you choose to pull the weight back to 90 degrees, then release it it will initially go to 270 degrees. When it is carefully set to swing in one axis, it remains on that axis. "It's a shame they keep it a semi-secret because the fact that the results could be affected by the motor and magnet is a bit disconcerting to me." Well I kind of agree with you there, albeit for different reasons. At a permanent Foucault display, the pendulum is the star and what happens behind the stage is not seen as being as important. I don't think they are trying to keep it a secret. I'm sure some permanent displays go into details about whatever mechanism is being employed. But I would be very interested to know all about the method of mechanism being used, just from a point of electrical engineering. You might find it interesting that as a teenager, I (with some friends) built a Foucault pendulum. The fun thing was that we built it within a hundred feet of a permanent display pendulum. From our observations on a pendulum built with construction site stuff, we determined our latitude to a fraction of a degree. We were pretty amazed that we replicated results of the permanent display pendulum at a fraction of the cost, built with junk.

Does it minimize error, as to not interfere with the demonstration, or is the amount of assistance so little it would be hard to contribute or counter the drift. A flat earther may claim it’s all fake. Otherwise the unassisted swing can prove the precession, but need to sort of keep the experiment in motion. Or knowing the rate of precession, the assistance adjusts as not contribute nor detract from the precession

    @@Kolopsych In some Foucault pendulums found in museums and public exhibitions, additional mechanisms such as electromagnetic drives or periodic "kicks" are employed to help maintain the pendulum's oscillation. These mechanisms are introduced to counteract the effects of air resistance and other sources of energy loss, ensuring that the pendulum continues to swing at a consistent amplitude. By using electromagnetic drives or periodic "kicks," the pendulum's oscillation can be sustained, allowing visitors to witness the gradual precession effect due to deception of evil men trying to control our world and make us believe there is no God but they are to be trusted. The Foucault pendulum experiment is a fake scientific demonstration not proof but to deceive people into believing the earth is turning.

    I think you're mixing up a variety of factors. In particular, those 23 degrees would be the angle between the equator and the ecliptic, the rough plane where we find the sun and planets. The angle between the equator and the Earth's axis is 90 degrees, simply because that's what defines the equator, and neither affects how far the pendulum moves anyhow. The directions that do involve the pendulum are: the direction the bob is swinging, the direction it is falling, and the direction to the attachment point. The attachment point and the fall direction are both fixed to the planet, so they only change direction because the planet rotates. (There are smaller influences too, but we're looking at a time scale of hours to days, where the daily rotation dominates.)

    Say, if you could attach a pendulum to a drone/helicopter, the same effect will still take place. This is because of the coriolis effect and the point of the experiment was to prove that the earth is rotating. A flat earth would not be able to achieve this same effect. The second point instinctly proves that it's not a flat earth because the location of the pendulum on the sphere would show different effects it would have at different latitudes. This is no different in trying to explain how a stationary helicopter "moves" with the earth's rotation? Same argument when people say an airborne object like a helicopter staying stationary should see the ground move underneath it but it doesn't. The "stationary" helicopter drifts with the air mass caused by coriolis. If that wasn't the case, we would be exposed to winds up to 1000km/hr as the earth rotates beneath the "still" air above. But that doesn't happen does it? So, the air is mostly moving with the earth's rotation and airborne objects move with it. Hence why aircraft/birds need power to move against it to get from one place to another horizontally. Otherwise, it would be virtually free travel. Just jump up in the air for a while, hover for a bit and land in a different spot at a later time. But no one's been able to do that have they?

    When the building rotates (with the earth), the pendulum simply rotates around it's vertical axis. That is, 'it spins in place on the wire''. But that motion is not side to side like the 'swinging' motion. Imagine you took a marker and marked just one side of the 'bob' so that it faces the front door of the building. Then set the pendulum swinging. The 'marked' side will always face the door. But at some points during the day it will be swinging to/ away from the front door, and other times it will swing side-to-side across the doorway. But the mark will still face the door all day/night.

    @@AndreasEUR Try again. I was talking about a different motion from the 'swinging'. If you think of the suspension wire, clearly the top of the wire is fixed to the building. And the 'bob' is solidly fixed to the wire. If the 'bob' didn't keep the same side facing the front door, the wire would get twisted around and around until it broke. Maybe the word I should have used is 'revolves', to separate the motion I'm describing, separate from the plane of the 'swinging'. Simply get a pen and put a mark on one side of the bob and notice that it's always facing the same side of the building as it swings all day. As the plane of the swinging appears to rotate around, knocking down the little pegs, the marked side of the pendulum is still facing the same side of the building. So we can say that the plane of the 'swinging' is fixed in 3D inertial space and the planet moves under it. BUT, the bob 'revolves' at the end of the wire with the building, facing the same side of the building as the building rotates around the earth. Two different motions.

And if that's the case, a jet going 500 mph at the North Pole heading south would take 12 hours to reach Malabo, Africa along the equator. However, the ground below the plane would be traveling 1038 mph eastward, playing havoc with landing on a N/S runway. And, Malabo 12 hours after takeoff would be on the opposite side of a spinning ball earth.

Conservation of momentum, and the importance of angular momentum. How did the plane get in the air? It took off. Therefore it's referential is Earth+Atmosphere. If two planes were flying side by side and you walk from one wing, you could potentially jump to the other wing (given you are not too high, too fast etc obvs, just an example) but it is true as that's how airjet refuel. They reach same velocity they are therefore in synchronous speed. The pipe dangling from the jet to attach the other plane does not hit the other jet at 1000km/h. Relative to the other plane, it's almost static. Being attached to the ground or not has NOTHING to do with relative speed. Angular momentum is everything in the case of plane since when the plane take off it takes the momentum of the earth. At no point it can remove itself form it. That's high school physics, it's Newton's laws. Also you are mistaking of measurement of rotation and moving at speed. The pendulum only measure rotation. Just rotation. First, the pendulum suffer of minor bias from the moment of the throw, but the way it is attached at the top makes it a low friction hang, pulled by gravity. It is part of the earth referential and the dome so no, you won't see it fly out of the wall. The only (or greater) forces are gravity pulling it down and the initial push on a plan of swing, therefore yes, it continues to swing on that plane and as the swing continue, the ballhead attachment at the top is the one rotating to keep track of the tremendous force of the swing and gravity pull down, as the dome continue to rotate with the earth.

    There are real pendulums you can see all over the world that demonstrate this or, if you'd like to save on gas, go out to the garage and build one yourself. If you want a visual to go along with it, use a piece of string and a paint bucket full of paint, with a hole in the bottom for said paint to dribble out of. Spin the pendulum in a loose oval and watch the magic. I recommend having a piece of wood or canvas underneath to capture it, it makes fascinating art.

    No, but they are related. Both the Coriolis effect and the precession of Foucault's pendulum are caused by preservation of angular momentum. The Coriolis effect is the apparent curvature of an object moving freely in a rotating reference frame. The pendulum remains in the same spot (at least it's centre of oscillation does).

  • @Hugh.Manatee

    @Hugh.Manatee

    11 ай бұрын

    From the way you phrased that, you were already really close to understanding why. Think about someone floating above a fixed point on the equator. The Earth's spin takes you directly east, so the floor doesn't appear to rotate under them. On the poles you are aligned with the Earth's axis of rotation so the floor rotates below them once every 24 hours. Now walk 100 meters (or a 100 yards) away from the pole and turn east. If you start walking east and want to keep walking east, you have to turn to make a circle with a radius of 100 meters. If instead you'd turn eastward at your initial point 100 meters from the pole and just kept walking straight you'd go to the equator, further south to a point 100 meters from the other pole and then back to your initial spot. Unless you're on the equator, east is not a straight line. The direction of east rotates as the Earth moves, so the pendulum rotates (or from the perspective of the pendulum, the Earth rotates underneath it).

    First, you need to learn how to use animation software(adobe animate, toon boom etc.), which might take a few days just to learn the basics. Then you may need to learn how to use editing software(Premiere, final cut etc.) depending on your work flow. Which might take a few days to learn the basics. And you'll need to learn some kind of audio recording software(Audacity, Audition etc.). Also a few days to learn the basics. You might want to draw some of the background with photoshop or similar software. Maybe a few days to learn the basics. And you might want to use some 3D models. In which case you'll want to learn how to use 3D software such as Blender. As for the difficulty, it's not the most difficult thing to do but it is challenging. Keep in mind every second of animation consist of 24 drawings. So in order to create a 5 minute animation, you will have to draw a total of 7200 frames(24frame*5min*60sec). Animation software does most of the work of course, but it's still very time consuming. Hope that helps!

    The way that I learned to visualize the "Foucault effect" is: Imagine viewing the earth spinning from the spin axis vector looking down towards the center of rotation of the earth (very far away, neglect perspective). From this vantage the equator is a perfect circle. (Lets call this the "High vantage point" or HVP) Now imagine placing the swinging pendulum at the north pole. From the HVP, the pendulum is swinging "in a plane" that is normal to the viewing vector. (Gravity vector for pendulum and viewing vector are the same) At this point the pendulum will have the greatest rotation visible from the surface (effect of 100% or 1.0X). Now if you relocate the pendulum in a different location on the earth (for the sake of simplicity lets always imagine the swing beginning in a local "north south" orientation), imagine what the swing "looks like" from the HVP. at 45 degrees latitude the plane of the swinging pendulum is tipped 45 degrees from the HVP. So, the viewer "Sees" less of the swing of the pendulum. (about 70% or Cos(45)) Now move to the equator and the plane of the swing of the pendulum is tipped completely 90 degrees to the HVP. (Gravity vector for pendulum and viewing vector are perpendicular) So, you can't really "see" the swing of the pendulum at all. This is the point where the effect is minimal or 0X. (0% or Cos(90)) It is how much "Cross section" of the swing can be "seen" from the HVP that determines the magnitude of the effect. In Engineering terms, it is also called the "Cosine Loss" similar to the power on Solar arrays as you tip them away from normal to the sun, or how much cross section of an electrical coil is exposed to a magnetic field as it rotates.

If the earth were actually flat would the north pole be the center, or the south pole? As pointed out before, they are each circled by separate constellations- and what of the equator? The fact that the math correctly predicts the different relative rotation over a fixed point at multiple locations demonstrates the validity of the spherical explanation, even if one does not understand the details or math.
