Plasma is usually introduced as the stuff of stars and fusion reactors, a searing soup of charged particles that has little ...

Preliminary results from two experiments suggest something could be wrong with the basic way physicists think the universe works — a prospect that has the field of particle physics both baffled and ...

Three thought experiments involving “demons” have haunted physics for centuries. What should we make of them today?

If you drop a light object and a heavy object from a tower, which one reaches the ground first? As you may recall from high school physics, this is a trick question. Neglecting air resistance, they ...
