Quantum field theory (QFT) is the basis of the Standard Model of particle physics. This video explains what QFT is, why it’s necessary, and how it differs from non-relativistic quantum mechanics.

Quantum mechanics powers lasers and precision measurements. A century-spanning perspective examines those successes and the ...

Quantum mechanics is both the most powerful theory physicists have ever devised and the most baffling. On the one hand, countless experiments have confirmed its predictions; the theory undergirds ...

Researchers have experimentally observed energy patterns that physicists have predicted for about 40 years. By arranging ...
