What is quantum physics? Put simply, it’s the physics that explains how everything works: the best description we have of the nature of the particles that make up matter and the forces with which they ...

Quantum physics is the study of matter and energy at its most fundamental level. A central tenet of quantum physics is that energy comes in indivisible packets called quanta. Quanta behave very ...

Federal officials seized 3,000 copies of Scientific American in 1950 in a “red scare” era of attacks on science. The move backfired and offers lessons for today ...
