A feynman digram is a visualization of possible particle scattering within in a probabilistic field. It depicts a particle interfering with its field through time. It is a doodle to figure, and cancel out, infinite and improbable loops within quantum interactions with fields. It isn't really applicable to other problems.
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)
@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.
what are meaning of 25 infinity dimmension of Hilbert matrix of course we can use it as intermidiate level of calculation but for me cohherent methods closeup to Paul Andrien Dircac can be used even Delta is infinity value at 0 but it's peak of probability unitariry as well....acording to Feynman infinity imagination not so easy to follow exactly the same :) it 's fine to be close to physical intuition but acording to cylinder of Einstein we get holes in sky, big bang neutron stars gravity waves much more evindent but space mision like LISA and probably much cheaper than LIGO....:)
evryday scan of the sky is well to detect more evidence of GRT not talking about Moon bases :) but in empty space (one hydrogen nucleus per m^3) or even less most probably cosmic void
so in such condition antimetter is existing in halo of Galaxy without interaction even interacting with barion metter is up to 0.0000000000001 accucrracy value taken from cylinder :) but enought to confirm calculation....
Wolfram Mathematica is wonderfull tool as well as Maxima in old times but capable much more things beautifull job of his team also acoring to neural package...so future is near about Honest Annie and Hal all together
@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
That talk also has a very nice conclusion, which is deadly serious. I did have visions of an ex-student with his magnificent grey beard wrapped around his Zimmer frame, whilst muttering something about solving the five loops diagram....
he had a great point about the value of creativity in solving problems
That was one of Richard Feynman's great strengths.
Did they ever find out how the 35 year debate is settled?

thank you all very much
Fast forward 13 years. Any news about 5 loops?
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)
I like the last conclusion very much. Nothing more powerful than a good idea. Computers never would do that.

“Science is the belief in the ignorance of experts.” - Richard Feynman
I thought it was interesting. I wish he had gone further into the Unitarian method. Apparently a lot of people didn't think so but I enjoyed it.
@DigitizedSelf I get your point now. Indeed, perhaps this is not really meant to be a TED talk
Fast-forward more than 5 years later, has a follow-up video been made?
+1 one year later
Apologies for the delay; I took the long, seven year, route. ;-D
The answer appears to be 'Probably not.', which is a shame.
RWBHere what? Can you give a link of the calculations
People go over things so quickly. HOW can we look at things at 10 to the -3?

does sheldon cooper works with you?
What if the good idea was a quantum computer?
A good idea will knock the socks off a quantum computer.

microsatelites can carry inteferometers by cheap Chinees racket tehnology as well by NASA, ESA all together :)

as well more sophisticated knowledge in wolfram/aplha

@robke136 Well, it's not like he's teaching you anything 'quite specific' though :-/
Feynman's jokes were much better!
Ummmm , my brain is overheating
I use an other thing than feynmann diagram.....
nice talk and the jokes are good:)
That talk also has a very nice conclusion, which is deadly serious.

I started to yawn at about halfway. I shan't make to the end.
jokes? were there jokes in this?
