Quantum field theory: an informative approach

In summary, there is no book that comprehensively explains quantum field theory without going deeply in the theory with formulas or complex description of the mathematics under the theory. Brian Greene's books are a great way to learn about QFT, but they are not the only option.

TL;DR Summary
Looking for a book that tries to explain the basis of quantum field theory in an informative approach, without complex formulas but with the spirit used by Brian Greene for his fantastic The Elegant Universe
I'm looking for a book that describes the quantum field theory without going deeply in the theory with formulas or complex description of the mathematics under the theory.
I know that this theory is really complex and it needs a deep knowledge of quantum physics in order to be understood.
But Brian Green succeeded in writing a book about String Theory for everybody, I'm wondering if such a book exists for quantum field theory too.

Well, Brian Greene's books are indeed fantastic but everything else than good textbooks about physics. You cannot understand quantum theory without math. A much more honest approach to make QT as simple as possible but not simpler is Susskinds corresponding volume in the "Theoretical Minimum" series.

Here is a fantastic book about quantum field theory, fully featuring the Vacuum Fluctuation Myth (the fantasy about QFT intended solely for lay people):
In the Introduction, he writes:
Martinus Veltman said:
we cannot assume the reader to be familiar with the mathematical methods of quantum mechanics, so he will have to swallow strange facts without the support of equations.
... not only strange facts but also strange fiction!

Veltman won in 1999 the Nobel prize for physics for much more serious work. He also wrote a serious textbook on quantum field theory,
which is free of virtual particle fantasy, featuring instead a valid formal approach - but it is therefore a bit more difficult to understand. This technically precise (though not mathematically rigorous) book contains not a single mention of the word 'fluctuation' or ‘virtual’. In the Introduction, he writes:
Martinus Veltman said:
No one should have an excuse not understanding this book. Knowing about ordinary non-relativistic quantum mechanics and classical relativity one should be able to understand the reasoning.
This much to your excuse...

A book about physics promising "mysteries" is usually not worth the paper it's printed on...

Three books and a video, now I can't say I don't have something to read at night :biggrin:
 

1. What is quantum field theory?

Quantum field theory is a theoretical framework used to describe the behavior of particles at a subatomic level. It combines the principles of quantum mechanics and special relativity to explain the interactions between particles and fields.

2. How is quantum field theory different from classical field theory?

Classical field theory describes the behavior of fields as continuous and deterministic, while quantum field theory considers fields as discrete and probabilistic. Additionally, quantum field theory takes into account the effects of quantum mechanics, such as superposition and uncertainty, which are not present in classical field theory.

3. What are the applications of quantum field theory?

Quantum field theory has a wide range of applications in physics, including particle physics, condensed matter physics, and cosmology. It is used to understand the behavior of fundamental particles and their interactions, as well as the properties of materials at a microscopic level.

4. How does quantum field theory relate to the standard model of particle physics?

The standard model of particle physics is a theory that describes the fundamental particles and their interactions. Quantum field theory is the mathematical framework used to develop the standard model and make predictions about the behavior of particles at a subatomic level.

5. What are the challenges in studying and understanding quantum field theory?

Quantum field theory is a complex and highly mathematical theory, making it challenging to understand and apply. It also presents conceptual challenges, such as the interpretation of quantum phenomena and the unification of quantum mechanics and general relativity. Additionally, experiments at the energy scales required to test quantum field theory predictions are difficult and expensive to conduct.
