TEDxCaltech - Zvi Bern - Feynman Diagrams: Past, Present, Future

[DigitizedSelf]

Awesome! Unfortunately I suspect that people, who get what Feynman diagrams are, often already know of the unitarity method (or N=8 SuGra for that matter)

[robke136]

@DigitizedSelf Well no, Feynman diagrams are 'common knowledge' in the field of physics, while the unitarity method is something quite specific. I have actually learned a lot in this TED talk

[DigitizedSelf]

@robke136 Well, it's not like he's teaching you anything 'quite specific' though :-/

[robke136]

@DigitizedSelf Agree, but he would never be able to explain his unitarity method to me in the 9 minutes. I am happy to have a vague idea about it, and if I ever get into a problem that I can not solve using Feynman diagrams, I will remember this talk and look up the method.

@robke136 That's nice, but I'm fairly certain you'd run into it quite fast if you look for efficient ways of doing QCD calculations in perturbation theory - none the less it's good you got an idea of it anyway.

My original problem was that I generally consider TED talks to be of interest to larger section of society, whereas this only has interest to a small section, namely the ones who know what Feynman diagrams are but don't do QCD calculations.

@DigitizedSelf I get your point now. Indeed, perhaps this is not really meant to be a TED talk

jokes nobody laughs at. that's funny
