The Dual Pythagoran Theorem - Greg Egan

"Much of the physics in the universe of Orthogonal can be understood as arising from fairly simple ideas in geometry. Although the physical consequences are sometimes very different from the consequences in our own universe, the geometry itself is still the same. This page describes one very simple example, which nonetheless underlies one of the most important scientific discoveries in the novel. It's also a result well worth knowing for its applications in our own world."
