The Lifetime of a Circle

Everyone thinks that a circle is endless. But actually it only goes around 188,753 times.

Interesting theory.

This phenomenon is demonstrated physically on a bicycle. After someone rides it approximately 4,326 miles (depending on the size of the wheel), the wheel mysteriously stops turning, and is irrepairably deformed. Those who have tried to repair a wheel like this have been unable to, thereby demonstrating your theory.

Mathematicians predicted this at 4,000 miles, so they were pretty close.

People in America hardly ever experience this because not many people around here actually ride the same bike that much. People in other countries - especially China - have much more experience with this.

Also, another geometric myth is that a true circle is perfectly round. It's actually an oval: 0.0000000056738239 percent wider along the horizontal axis than along the verticle. The reason for this is a bafflement to scientists. Any attempts to computer generate a perfect circle result in an oval, and any attempts to draw a perfect circle on paper also result in the same. This is the reason Pi goes to over a million digits.

It's also the reason that you have to replace the tires on a car so frequently. The non perfect circle puts additional wear and tear on them.
