what's QFT even useful for again?

Do you tons of math so you can make better predictions which my differ by 0.00001% from more inferior theories.

my chemist friend told me that it's barely has any predictive power. Is this not true?

>> No.10893899

>>10893885
it's not true. the LHC experiments have published thousands of particle physics papers and all of them are predicted very accurately by the standard model -- typically what they use to calculate their predictions are simulation software like Pythia or Madgraph, and you can download those and try them out. they give you super accurate numbers for basically every process in particle physics (the only exceptions being very obscure parts of the SM like e.g. sphalerons)

Why would you bother learning QFT when you could work on making TOE.

>> No.10893911

>>10893901
every string theorist needs to know QFT very well as foundational material, same thing with brainlet quantum gravity like LQG. it’s analogous to how you need to know mechanics before quantum mechanics and you need to know quantum mechanics before QFT
