How was pi found....

The key discovery by ancient mathematicians was that the ratio of a circle’s circumference to its diameter is a constant for any size circle and they named that constant value PI.

NASA uses 15 digits of Pi, and the Preserverance Rover missed its landing site on Mars by 1.7 kilometers

Someone explain to my why it wouldn't work ...Why couldn't you, with string , wrap a cylinder in 1 perfect loop then compare the circumference length of the string to the radius or diameter?

Creo que es más fácil pensar en las veces que cabe el diámetro de una circunferencia en su propio perímetro. Sin más.

... Basel, Euler, and lighthouses

I think they just divided the circunfere by diameter...

I mean... no

Así no fue encontrado.Esa es una de tantas explicaciones.

You can calculate pi to the 1 millionth MILE away from the decimal point and it never repeats and never develops any pattern...at least that has been detected to date. It's a bizarre number, in that no-one will ever know what the value EXACTLY is.

People didn't have such a device 4,000 years ago.

This explains nothing

When will this end? I'm sleepy, is this a film?

Cool

@grok 如何使用蒙特卡洛算法计算π的值

They found him in a boat, with a tiger

BS

That's kinda overcomplicated. Just do a circle measuring 1 in diameter with a rope, and rope will have the length of pi

That famous phrase 'An image is worth a thousand words' is not by chance! 👏🏻👏🏻👏🏻

pffttt that's not even π That's just the perimeter of the paradoxical infinite sided 0 length segment polygon.

Ancient math was really just rolling a circle and going “wait… why is it always a little past 3?” 😭

Proved this in secondary sch btw

cool

Pi was calculated to an approximate value about 3500 years back in India. Rig Veda texts tell us how they solved the squaring the circle and circling the square problems. They used ropes to find a ratio between the side of a square and diameter of a circle with same area.
