I don't get why this troll physics is wrong.

AI Thread Summary

The discussion centers on the flaws in a troll physics scenario that claims to approximate the perimeter of a circle by removing corners from a square. Participants argue that this method fails to converge to the actual circumference because the perimeter remains constant at 4, regardless of the number of corners removed. They emphasize that true convergence requires the path to approach a smooth curve, which this method does not achieve. Additionally, the conversation touches on the definitions of perimeter and the implications of using different norms, concluding that the example misrepresents the relationship between perimeter and pi. Ultimately, the flawed logic leads to an incorrect assertion that pi equals 4, which is fundamentally incorrect.

Problem?

yeah. On several counts.

1] How does multiple wraps of fishing line result in the circumference? You do know what a circumference is, yes?
2] Where's the pipe come from? (bad copy editing I'd guess)
