Sure, you can cut a pie into pieces, but what if it’s in four dimensions? Using spectral graph theory, mathematicians have solved a decades-old problem. Graph theory uses nodes and edges (dots and ...

Using spectral graph theory, mathematicians have solved a decades-old problem. Graph theory uses nodes and edges (dots and lines) to represent data. If you’ve ever drooled over a cherry pie, cut into ...

Math enthusiasts around the world, from college students to rocket scientists, celebrate Pi Day, which is March 14 or 3/14 — the first three digits of an infinite number with many practical uses. Many ...
