Classical field theory is a research area in theoretical physics that studies continuous fields, such as electromagnetic, gravitational, and scalar fields, within a pre-quantum, typically relativistic ...

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.

Susskind and Friedman follow their collaboration on Quantum Mechanics by probing the mathematical nitty-gritty of field theory and Einstein’s theory of special relativity in the third installment of ...
