In the 1860s, James Clerk Maxwell recognized the similarities between electricity and magnetism and developed his theory of a single electromagnetic force. A similar discovery came a century later, ...

The “Standard Model” of particle physics is a set of equations that describes accurately how a small number of fundamental particles interact, and how they form visible matter. But we know that this ...

The Large Hadron Collider (LHC) can achieve an energy that no other particle accelerators have reached before, but Nature routinely produces higher energies in cosmic-ray collisions. Concerns about ...
