How did the quantum field theory come about?
assistant
It was developed in the 1930s by physicists such as Max Born, Werner Heisenberg, and Paul Dirac. Quantum field theory is the mathematical framework for understanding the behavior of subatomic particles and their interactions. The theory was originally developed to describe the behavior of electrons and photons. However, it can also be used to describe other particles, such as quarks, neutrinos, and gluons.
