The four-color theorem is simple to state: Given a contiguous map, is it possible to color each region with one of four colors such that no neighboring regions share a color?

The Four-Color Theorem Has Haunted Mathematicians for Decades. It Just Got a Rare New Proof, but Some Still Long for a Simpler Solution

The famous problem asks whether a map can be filled in with only four colors such that the same color never borders itself. It has been solved with the help of computers, but some experts suggest an elusive, short answer is out there

Simulation of gas structures as electrons were removed from helium by radiation emitted by early stars and black holes.
