I don't own either, but I clicked "surprise me" on Amazon. Both had pages of equations: partial derivatives in Huang.Demystifier said:Huang, Fundamental Forces of Nature

Instead of bothering you with relativistic QM it's rather a good idea to use the time to learn the QFT formulation of non-relativistic QM to see that in this case it's an alternative equivalent description (although historically it's called "second quantization").

You were just (un)lucky, the books have a rather small number of equations.Vanadium 50 said:I don't own either, but I clicked "surprise me" on Amazon. Both had pages of equations: partial derivatives in Huang.

I am just starting to teach myself math. I don’t have money for school so I’m teaching myself. I just want to know the facts of QFT for now before I’m done teaching myself math. I understant that particles and waves and forces are due to underlying excitations of these fields and that’s about it.PeroK said:Whoever then has the effrontery to study physics while neglecting mathematics must know from the start that he will never make his entry through the portals of wisdom.

Do you know any good self teaching math books?

There are a number of Internet-based options now, such as Khan Academy and others that you may have to subscribe to, such as brilliant.org.BadgerBadger92 said:I am just starting to teach myself math.

There's also a website that covers the entire UK high-school mathematics syllabus:

Stewart's calculus was how I learned calculus. Pretty good book I'd say.haushofer said:

Now if you just want to know QFT at a laymen perspective, Sean carroll has pretty good explanation of what it's

If you want to be able to do QFT (like calculate) you'll need multivariable calc, diffEQ, linear algebra, complex integration. Anything less than that is hopeless.

Don't forget some group/Lie algebra representation theory!

Absolutely agreed. I was referring to the absolute minimum. You're correct that a sophisticated understanding of QFT requires lie algebra and representation theory, however a lot of introductory QFT texts do not require it as a prerequisite. If your goal is to read weinberg or more sophisticated treatments, yes it helps a lot of understand how lie algebras work, which is treated somewhat in graduate level QM texts. The rest usually for most students is picked up as you go while learning QFT. For example, peskin, srednicki, and even weinberg all include sections that summarize lie algebra or representation of the lorentz group. The first time I learned about dynkin index and casimirs was from a QFT textbook.vanhees71 said:Don't forget some group/Lie algebra representation theory!

M. D. Schwartz, Quantum field theory and the Standard

Model, Cambridge University Press, Cambridge, New York

(2014).

Then you are very well prepared for Weinberg's 3 volumes and

A. Duncan, The conceptual framework of quantum field

theory, Oxford University Press, Oxford (2012).

which is an ideal complement to Weinberg's books.
