Скачать или смотреть Visualizing π with Rotating Rods | Why Pi Never Repeats

What if you could watch π in motion instead of just memorising 3.14?

In this video, two rods are fixed together. The first rod spins slowly around the centre, and the second rod spins π times faster. As they turn, the tip of the second rod draws a path in space.

If π were a simple, repeating fraction, that path would eventually loop around and close perfectly. But because π is irrational and its digits never repeat, the path never closes. Each new loop just barely misses the previous one, creating an endlessly changing, never-repeating pattern.

This is a powerful visual way to understand:
• What it means for π to be irrational
• Why “never repeating” is more than just a textbook line
• How motion and geometry can make abstract maths feel real
