bhobba reacted to Demystifier's post in the thread I Simulating physics: the current status of lattice field theories with
Like.
I don't think that's exactly true. What is impossible is to make the action chiral, but locality and hermiticity should not be a... -

bhobba reacted to Demystifier's post in the thread A Is It Known For Sure Infinites In QFT Are Caused Using a Continuum? with Like.
There are two kinds on infinities in QFT, UV infinities and IR infinities. UV infinities are due to using a continuum (in both space and...

bhobba reacted to Gavran's post in the thread I About the existence of Hamel basis for vector spaces with Like.
It can be shown that if the Axiom of Choice is false, then there are vector spaces with no Hamel basis. The exclusion of the Axiom of...

bhobba reacted to PeterDonis's post in the thread Insights Why Entangled Photon-Polarization Qubits Violate Bell’s Inequality with Like.
Reopening thread to reply. It means what relativity says it means. We're discussing physics here, not philosophy. Relativity of...

Skeptical.
But what does it actually mean? The Thing-in-itself is unknowable. Only representation and observation are knowable. (I took those two... -

Of course. All have erratas.

Speaking of Folland's books, they are notorious for typos. Here's the errata for his 1st edition of the QFT book.

bhobba reacted to mad mathematician's post in the thread Quantum "WHAT IS A QUANTUM FIELD THEORY?" A First Introduction for Mathematicians with Like.
Well, I've got two books that treat QFT for the math-geared ahead (I double majored in maths and physics), they kind of old. There's...

bhobba replied to the thread Quantum "WHAT IS A QUANTUM FIELD THEORY?" A First Introduction for Mathematicians.That's not what I meant. I meant a treatment, while still somewhat informal, is still rigorous, as found in...

bhobba posted the thread Quantum "WHAT IS A QUANTUM FIELD THEORY?" A First Introduction for Mathematicians in Science and Math Textbooks.The book is fascinating. If your education includes a typical math degree curriculum, with Lebesgue integration, functional analysis...
