Quantum field theory (QFT) is the basis of the Standard Model of particle physics. This video explains what QFT is, why it’s ...

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 ...

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 ...

I will discuss the notion of a classical field theory as understood by mathematicians and then go over a number of examples: sigma models, gauge theories, bosonic strings, relativistic particles ...
