After centuries, a seemingly simple math problem gets an exact solution
It's fascinating how a problem that looks at first glance like it belongs as a basic homework problem in a calculus textbook turns out to be so difficult.I'm curious if there are lists of other problems that are similarly easy to understand in a few seconds, that seem like they'd be similarly easy to solve, but which turn out to be fiendishly hard like this one?Especially ones that can be visualized easily geometrically like this one.
