Meanings of quantum field theory in English

Generalizations of spin networks later appeared in certain kinds of quantum field theory.

And quantum field theory was failing to calculate how this could be so.

General relativity and quantum field theory confessed from the start that they were just approximations: pushed to extremes, they both yielded obvious nonsense.

The present lack of any meaningful answer to those questions reveals "something deeply wrong with our understanding of quantum field theory", Smolin says.

This theoretical work revitalized the nearly moribund quantum field theory and gave birth to QCD (quantum chromodynamics), the theory of the strong interactions.

Our review presents these developments from the perspective of the underlying microscopic physics, using the language of quantum field theory, relativistic kinetic theory, and holography.
