The Foucault Pendulum installed in the Panthéon in Paris is one of the most famous scientific experiments in history, designed to demonstrate the Earth's rotation visually and directly. In 1851, after weeks of work, he recorded in his journal that he made this discovery at 2:00 am working with a pendulum in the cellar of the house he shared with his mother. Latet that year he performed the first public demonstration in the Panthéon under Napoleon III. He chose the building for its great height, which was necessary for the pendulum to swing for a long time without stopping. The installation we see in this video recorded in the Panthéon is a reproduction. The original pendulum used by Foucault in 1851 is preserved and displayed at the Musée des Arts et Métiers in Paris.

The symbol π was used for the first time by a self-taught mathematician William Jones in 1706, on his paper titled "Synopsis palmariorum matheseos". Later it was popularized by Leonhard Euler, who adopted it in 1737.

@marcopozzi96 @CelticFC Why would I do that exactly?

@PhysicsForFools @CelticFC Hahahahah fucking cry

FULL TIME AT PARADISE The race is over. Champions. 🏁 #Champion5 | #CelticFC🍀🏆

@ICRscience What do you mean by "constant decay"? Are you talking about decay rate (which changes) or the decay constant (which doesn't)? I suspect you don't really know what you mean. Let me see your working.

The millions of years result is often a product of the assumption of constant decay rather than an objective measurement of the earth's true age.

Leonhard Euler was the first to introduce the symbol of function f(x) and systematically incorporate it into calculus. This notation is now foundational in mathematics.

@benwehrman How old were you when you turned around your miserable school experience and realised you were actually smarter than everyone, scientists included?

Globers say that when you send a balloon up 22 miles, the reason why the Earth doesn't spin away at 1,000 MPH is because "Gravity causes the atmosphere to stick to the ball." But at the same time, when you look anywhere on Earth, the wind flows freely in all different directions. It is physically impossible for both of these wind dynamics to be true at the same time.

@BrockRiddickIFB All the same, the equation for a meniscus' height goes contain a pesky 'g'.

This guy thinks a meniscus is caused by gravity... 😀

@GloBAAL_Failure @LGRWkyle @MmisterNobody Is it beyond you to understand rotation around a fixed axis? Also, if the 'wobble' you refer to is the earth's precession, that occurs with a period of thousands of years.

@LGRWkyle @MmisterNobody The Earth is stationery and immobile, as measured. Reconcile the following with your theory.

Sorry folks, but you are not living on a spinning, curving ball rotating at 1,039 mph at the equator, orbiting the sun at 66,600 mph, moving through the Milky Way at 450,000 mph, and racing through an ever-expanding universe at 1.3 million mph, all while Polaris stays fixed above the North Pole.

It’s strange to live in a world where people think every scientist, researcher, or doctor is a shill - but an anonymous X account is telling the truth.

@simonmaechling Expertise is "indoctrination", apparently 🤪

@realdefender45 It's weird how many people are treating this conversation as if it actually happened.

Had lunch w a guy that worked at NASA. I asked him about his thoughts about us going to the moon. He flat out said, “we never went, not now, not then.”

@BrockRiddickIFB In one of those models the sun is only visible from half the surface at any given time; in the other it's visible from everywhere at all times. Which of those do you think matches the reality of our experience?

@brashua431973 @Chris_GWW @otokyo__ The great thing about an imaginary entity is that you can arbitrarily assign to it any property you like 👍

@Chris_GWW @otokyo__ God exists outside of time and space. If he didn't, then he wouldn't be God.

Dear atheist, What if, after you die, you find out that God is real all along? You lose.

@benwehrman You seem to be struggling with the meaning of the expression "downward drop".

A flight from New York 🇺🇸 to London 🇬🇧 covers 3,459 miles (5,566km) of distance. Based on the official Earth globe measurements (radius = 6,371km/3,959mi) given to us by NASA, the amount of Earth curvature drop that should take place over the course of that USA ---> UK trip is 1,298 miles (2,088km). An SR-71 Blackbird has been recorded making this exact trip in ~2 hours. So, over the course of that flight, the plane would have to drop downward by 650 miles every hour. That's 10 miles per minute. Or approximately 1 mile (1.6km) every 6 seconds. Ask any high-speed jet pilot if they experience this 800 feet PER SECOND downward drop while they're flying, or have to dip the nose of their plane down to follow this "curve" as they fly. Of course they will laugh at you. This is ridiculous. Pilots do not have to account for these insane giant ball measurements, because they do not exist.

@BrockRiddickIFB The movement of water corresponds to a stretch of the earth's oceans of only around one part in ten million. I bet you didn't realise that. You probable also don't know that the moon also causes a periodic 'wobble' in the earth's orbit round the sun.

@benwehrman Everyone takes the piss out of flat-earthers. Why would pilots be any different?

I asked 2 more pilots, "Globe or Flat?" on my recent flight home from Canada. "It's definitely flat." 2nd guy: "Yeah." "It's not even a conspiracy, it's just real." Is every veteran pilot conspiring to prank me?? Or are they simply aware that there is no 1,000MPH of Earth spin to account for, or multiple miles of downward nose-drop per minute needed to follow the curve of a ball 🤔

@BrockRiddickIFB Refer to the answers you received on any of the multiple times you previously posted this. Nothing's changed.

@FELibrary_ Let me see if I've got this: Q. What happens if an object is denser than air? A. It sinks Q. But why does it sink? A. Because it's denser than air 🤪

@FELibrary_ There's a difference between *what* happens and *why* it happens that you guys don't seem to understand. *Why* do denser objects sink exactly?
