field theory
- noun
- /fiːld ˈθɪəri/
- Specialized
- Yeah, in grad school I taught myself field theory with this book.
- quantum field theory
- effective field theory
- unified field theory
So now you equate some field theory with a full string theory.
- So now you equate some field theory with a full string theory.
- His name was Albert Einstein, and that book was the unified field theory, the theory of everything.
- That I, I, I still want there to be a universal field theory that maybe I'm cherry picking to try to dream one up.
- And as far as I can tell, it seems like it's not a good PR move during the Cold War to claim that Russia's figured out unified field theory.
- So, so we got the sense of what quantal field theory is, is that a big leap of, of an idea that particles are fluctuations in the field?
- And then I guess that was then the bedrock on which Feynman and Schwinger and Tom and Arga built quantum electrodynamics, which is the first kind of complete quantum field theory.
- So you can have a, a field theory without gravity on a boundary.
- Yeah, in grad school I taught myself field theory with this book.
- I use this book to teach myself field theory.
- Do you want to program a quantum field theory.
- Sure, you could search for all renormalizable field theories and try to do an exhaustive search.
- That was the free field theory, but part of it made the interactions.

The standard model, some basic implications of quantum field theory, and the questions of structure formation.

In the modern quantum field theory way of thinking about things, the real thing that exists are quantum fields.
-
So I learned field theory on my own with with this book.
-
It's a characteristic of gauge-invariant field theories like those that constitute the standard model.
Academic text (2005) -
Even Jordan's pioneering work in quantum field theory was not immediately appreciated.
Academic text (1999) -
Atomic physics teaches a universe of elusive particles; field theory teaches a universe of electromagnetic waves and gravitational fields.
Academic text (1998) -
Quantum chromodynamics (QCD), the current theory of the strong interactions, is a field theory of quarks and gluons.
Academic text (2003) -
My research focuses on quantum mechanics and field theory, specifically how fields influence particle behavior.
-
In my physics class, we learned that field theory helps to explain the interactions between matter and energy in space.
-
The development of field theory has revolutionized our understanding of electromagnetic waves and their properties.

Morphology
The phrase is compositionally transparent: 'theory' (a set of ideas) combined with 'field' (a domain or region, especially in physics/maths) yields 'a theory about fields' which a B1 learner who knows both words can reasonably infer. Although the full technical content requires subject knowledge, the basic meaning is directly derivable from the constituents and follows a common noun-noun naming pattern.
Etymology
Field theory gets its name from imagining a wide field where every spot has a number (like temperature) and those numbers can change and affect nearby places. That's why field theory means a 'theory' that explains how such fields across space and time behave and make things happen.
