Richard Feynman Lecture 4 Part 1/7: Problems in QED and The Standard Model of Particle Physics

[HiAdrian]

LOL, this video is overrun by spammers; i wonder what singles it out in causing this.

[nascendus]

thank you youtube for making this available to me through your channel

[mikemartin1705]

Definitively: Feynman Rules!!!!! Heheheheheheheh!!!

I Love The Video It Can Increase My Knowledge Richard Feynman Lecture 4 Part 1/7 Problems in QED and The Standard Model of Particle Physics

[croncong]

Nice Video That You Share , So Very Nice Thanks You iscusses the problems which motivated the development of Quantum Electrodynamics and futher problems in the Standard model of particle physics which includes the Electroweak

[fitnesus]

I Really Like The Video From Your Electrodynamics and futher problems in the Standard model of particle physics which includes the Electroweak theory developed by Steven Weinberg,

[lupabuatchannel]

Your Video Is Very Useful Sharing mesons and baryons was created which were organised in baryon octets and extended into baryon decouplets as new particles were detected with different characteristics which influenced their decay transistions.

When we find it ie truth. How do we, or will we know it. Proof, truth is a natural comparison. To what? The previous proof?

[MAJAITI]

Great physic lecture!

[IlRezzonico]

@MAJAITI physic? Physic is medicine. ("Throw physic to the dogs, I'll none of it" - Shakespeare, Macbeth) This is physics. :-P

[sprattysy]

great vid you have here

[ebutemetube]

Did I just pay £2.40 to not hear, why I don't understand quantum mechanics?

[thegeffc]

good work here

[chenalos]

From the way he describes it it looks like he's trying to compute the electron's amplitude from one to two. However there is a nearly infinite number of ways a photon can be emitted and reabsorbed in the process which makes the scenario for the amplitude have an infinite number of solutions. In order to correct this they must subtract from the equations all other means to get the amplitude except for the one they are looking for, thus presenting the solution.

very interesting video thanks

[DeltaNordicAdvance]

the lower resolution is better - faster to download!

[prchecker]

you have some great stuff here

10^-100 cm, that's a comical illustration!

[123conundrum]

240p, we meet again.

[jeystonemusic]

@123conundrum 240p we meet again dickhead we meet again

[Squirlol]

@jeystonemusic yeah it's so important to have physics lectures from 1979 in HD.

[eggsstink]

Feynman multiplies by infinity.

[keviar245]

if only the quality was atleast 480p
