It is something like the "Holy Grail" of physics: unifying particle physics and gravitation. The world of tiny particles is ...

Mathematicians have struggled to understand the moduli space of graphs. A new paper uses tools from physics to peek inside. “That’s a super hard problem. It’s amazing they were able to,” said Dan ...

Quantum field theory marries the ideas of other quantum theories to depict all particles as “excitations” that arise in underlying fields. The British physicist Paul Dirac started the ball rolling in ...

For experimental physicists, the latest measurement of the muon is the best of times. For theorists there's still work to do. If we take out all the matter, neutrinos, dark matter, cosmic rays, and ...
