The amplituhedron, a shape at the heart of particle physics, appears to be deeply connected to the mathematics of paper folding.

How did the complexity of the Delian problem, an ancient Greek mathematical riddle that baffled brilliant minds, reshape our understanding?

I'm in a coffee shop when a young child dumps out his mother's bag in search of fruit snacks. The contents spill onto the table, bench and floor. It's a chaotic—but functional—solution to the problem.

If you correctly recall the elementary trick for order of operations, solving this problem should be a breeze.
