Physics Math be like…

Its about a certain form of reinforced learning, called Temporal Difference Learning:

The calculation is called simple because it follows directly from the definitions above. Simple means more like “follows directly from definition without fancy math tricks”, not " everyone who can read could solve this in 10 minutes".
I think this is also mostly math related, not physics?
I had a good laugh anyway. Good meme

We’ve got the time dependent polar Schrödinger equation any time we want to pull out a ridiculous looking equation in pre-graduate level physics.

I thought these were AI generated at first.

Even worse are the ones that go super slow.
And now we pluck the 3rd string in the 5th fret with our thumb. Bum
The next step is to release the string and move over to…

This trivial result is left as an exercise to the reader.

We should have never given physicists the alphabet.

Math majors: “Duh.”
Non-math majors: “And then a miracle occurs…”

I’m a mathematician; that shit on screen ain’t simple.

My Casio watch calculator has none of those symbols so I don’t think it is so simple.

My calc professor would say that stuff and be absolutely giddy despite rows of barely adults with confused faces looking at him.

That particular line looks like application of some rule or substitution of a term - on it’s own, simple
- Prunebutt ( @Prunebutt@slrpnk.net ) English5•2 months ago
I think it says “simple” as due to not discourage the reader, 'cause it’s probably a simple substitution in context which just looks complicated at first glance.

Stochastic differential equations?

So uncomfortably true!
I recall spending a (large) number of weeks struggling through Elementary Stochastic Calculus, which had an incredibly misleading sticker on the cover proclaiming:-
“This book is suitable for the reader without a deep mathematical background.”

I think that translates to only requiring one phd to understand

To be fair, it looks simple compared to really difficult stuff
