A Nobel Price winner seems to disagree with you.
From the article:
> the American physicist Frank Wilcjek, who worked with Feynman in the 1980s, once wrote: “The calculations that eventually got me a Nobel Prize in 2004 would have been literally unthinkable without Feynman diagrams.“
- improbable22 7y agoSure, but that's an odd reading of GP's "graphical notations like this one". Feynman diagrams are very useful, and made respectable lots of other graphical notations. There's a nice book on this: https://www.press.uchicago.edu/ucp/books/book/chicago/D/bo3534300.html https://www.press.uchicago.edu/ucp/books/book/chicago/D/bo35... But diagrams as a replacement for writing out tensor indices, like in TFA, which was what I presume GP meant... these have not proven widely useful. I guess people doing tensor network things use them.
- knzhou 7y agoDiagrammatic intuition is good. I use Feynman diagrams every day. But nobody computes with Feynman diagrams, they use them as an intuition aid to tell them what to compute, and that computation is done using standard notation.
