a physics author called me nigger once.

Mathematicians believe this is a legit way of proving theorems.

>condensed matter, which has as much (if not more, due to the exotic topologies afforded by the presence of quasiparticles and defects) mathematical richness than high-energy physics

LOL

>your notation uses commas in subscripts where no partial derivatives are implied

confirmed for not knowing gr, sugra, et al brainlet tier.

it's hep phenomenology from the 90's. What did you expect?

nice thread.

What is the most difficult degree?
I'd say physics.
Because it's heavy on mathematics and you don't really know what you are doing neither the mathematics you are using.

He's not wrong.
It's like learning a language when you're a child, you do it effortlessly.
Very easy compared to adulthood.

Absolute pitch cannot be acquire after you're ten or something.
The critical period is closed and your neurons are pruned forever.
People who were proficient in mathematics from an early age have a brain structured specifically for mathematics.

this is a blue board you fucking gaylords.

it is pretty clear why this might be the case: the sisters offspring are children the man can be absolutely certain he is related to.

he came up with a novel solution to einstein's equations, it's not particularly physically significant, but it's not nothing.

it's not a matrix, clearly, the spectrum is uncountably infinite.

but it is a very hard theory to follow and at the same time we've done it a bit more extremely than we've ever done it in the past.... It's topologically designed to be that way, and you can't undo that, but we can diminish the effects of it... we may have gone too far in a few places.

look, any proof of any of the outstanding millenium prize problems is going to involve Interuniversal teichmuller theory, post anabelian froeboid geometry and vector calculus. You should learn these first.

how do I find riemann normal coordinates around an arbitrary event?

space is countable

I have not been entirely correct with the placement of the lower indices on the christoffel symbols, however since spacetime is torsionless and the christoffel symbols are thusly symmetric in their lower indices it is a moot point.

*pulls your strings*

Why write vector fields on manifolds as
directional differential operators? Sure, you can do it, its an obvious isomorphism, but why not say that a vector field is just a map from the manifold to the tangent bundle where the image of every point is an element of the corresponding tangent space. That seems more natural, I dunno, I think differential geometry has crunched my brain.
