How fun do you want your particle physics lecture? Nima: Yes

I actually enjoyed this, particularly Nima’s sparsely elegant diagrams.

Hey Nima, standing ovations!! Just one little problem: on one hand you said that the set of physical laws governing our universe is inevitable, therefore our universe should be pretty stable, but on the other hand you compared our universe to a pencil standing on its tip, that is a massively un/meta-stable, and therefore improbable system. I am sure you are right, just witch of both conflicting statements is correct :).

He uses the pencil analogy in a lot of videos, go watch what he really means.

If everything is really only fields - why are we talking about particles at all ??

electromagnitism is not "stronger" than gravity 37:40

+N Marbletoe , Correct!! If the field equation is correct then the 'weak' gravitation force can collapse mass to a black hole - and in the process overcome the resistance of electromagnetic force, weak nuclear force and strong nuclear force

It most certainly is....we see it mainly at small distances. The proportionality constants of electrostatic interaction and gravitational differ by around 20 orders of magnitude. The reason that we see gravity being so strong at large distances is that most things are electrically neutral so the net charge tends to be far smaller than 10 orders of magnitude than the mass. A lot of the strength of the electrostatic interaction goes into actually holding matter together. The best illustration of the relative strength of electromagnetic and gravitational interactions is the atom; mass of the nucleus barely plays a role in the binding energy of the atom...but the charge does.

Gravitational collapse is also due to how the gravitational energy varies as N^(5/3) versus total electrostatic energy which is basically 0 (electrons and nuclei charges cancel) and the relativistic energy of all the electrons varies as N, where N is the number of atoms in the star. When N is large enough (chandrasekhar number) the minimum groundstate energy basically becomes -infinity and so the star collapses. Over here, gravity doesn't overpower at microscopic scales... it's the sheer mass which makes the total gravitational force really large.

Total disgust at his use of the term 'squiggly figures'!!! They are Feynman diagrams and the speaker would not be worthy to wipe Feynman's boots
@gilgameshuvakhshatra76297 жыл бұрын
Feynman himself refers to the diagrams as "squigly". Nothing offensive intended. As for boots, the speaker does not need to when you are around.
