I’m too deep in this rabbit hole to stop. Wigner’s classification got me hooked. Where are the nostr #physics nerds at. 
Discussion
🙋♂️ not sure if I’m knowledgable enough to understand this though, what are the prerequisites?
Oh god the way I learn is so scattered I don’t even know. I think I just started peeling the onion on Lie Group, lie algebras, representation theory (woits book is really good). Once you realize that so much of physics is based on irreducible representations of symmetry groups things start getting really interesting. Understanding what SO(2), SU(2), means, how it relates to quantum observables, pauli matrices, etc… so much to explore. Chatgpt helps a lot, it’s an infinitely patient tutor.
This got me hooked https://en.m.wikipedia.org/wiki/Particle_physics_and_representation_theory
Have you looked at the basic math of QM yet? The notation and generalization of vectors and inner products by way of Hilbert space is very nice. There's a good video series here: https://www.youtube.com/@quantumsensechannel/videos
I know about Hilbert space and the general notion in QM, but this was a very nice channel! Glad you introduced it to me, refreshing all topics one by one!
Lol. Years and years ago, I was having drinks with a friend. He said the meaning of life, or explanation of God if you will, was a math equation.
I've never been able to brush off his 2am quip.
I think math... leading to physics and then physics we don't yet understand like quantum theory is the next step closer to understanding.
I watch Interstellar and old star trek episodes once a year just to vibe on it.

It does not explain interference clearly.
Yeah I stayed at a holiday Inn last night
It’s all too fuzzy for me!
I recommend checking out Theoria Apophasis. Quantum just means numbers, and is often used as a sort of magical metaphysical thing
Ken Wheeler is the foremost expert on the Ether/Electromagneticsm. His channel Theoria Apophasis is a must watch. Nature is divinely simple
Have you read Feynman’s Lectures on Physics, Vol 3? First few chapters, describing the double slit experiment, at least through to the part about turning the light on and off. Best intro to the mysteries of quantum mechanics in the world.
Read that and ask yourself HOW THE FUCK CAN THAT BE TRUE.
Feynman, like Einstein, was great at math, but they were physicists first and foremost.
Much cooler when you explore this phenomenon in the context of quantum information theory. When you take out many degrees of freedom in the physics and just focus on the transformations on quantum amplitudes things get less spooky. Ok it’s still a bit spooky.
Susskind has a mind blowing theory called ER = EPR where he makes the case that entanglement has similar properties to worm holes 🤯 there may even be quantum wormholes connecting entangled particles. QM is a lot of fun 😁
pretty sure this is what led wolfram to his hypergraph theory of everything 😂 have you seen his latest blogpost on it?
i really like his discussion of the branchial space (what he calls the quantum mechanics part of reality); branches world vs matter world is such a nice analogy imo
oh might def not be latest at this point lol 😂
Im too dumb to understand this stuff
No ur not
it sounds more complex than it is. general idea is that everything is a state machine, and the quantum realm is where the set of “allowed” state transitions are explored (hence the name branch-ial, they branch furiously)
where the branches actually move is what “matters” (get it? matter/material world)
time is the weird moment of collapse of the branchial to the material (i think, kinda guesstimating)
quantum computers are clever because in the material world you have to physically explore every path of a problem; the quantum realm of branches moves at a tremendously faster rate comparatively (in path exploration) than materially needing to calculate every state
being able to frame questions such that you can access the branching process of particles is an enormous speed up for searching a problem space
"So how is the effort to try to find a fundamental theory of physics going to work in practice? We plan to have a *centralized* effort that will push forward with the project using essentially the same R&D methods that we’ve developed at Wolfram Research over the past three decades,"
They are going to fail.
Ok frens, once we all get the decentralized web figured out, I say our next big project should be to unify QM and general relativity into a single theory.
We should probably try to figure it out before the technological singularity hits, bc who knows what the hell’s gonna happen sixty seconds after that …
Who’s with me? 🤓
I hadn’t heard of ER = EPR, but I like it.
Have you heard of the 4-geon model of elementary particles by Mark Hadley?
“It has been shown by Hadley that the logic of quantum mechanics is consistent with general relativity when closed time-like curves are permitted.”
Closed timelike curves in general relativity are pretty interesting. They give rise to the “grandfather paradox” which Kip Thorne explores in his 1994 book Black Holes and Time Warps.
Seth Lloyd's "Programming the Universe" and Wojciech Zurek's work on Quantum Darwinism are required reading for anyone on the intersection of computer science and physics.

I remember that's a NY girl who plays instruments who talked deeply about this topic

Love the topic even though I don’t understand most of it
I'm a physics nerd but quantum physics is not my bag, man. I only get into it far enough to be able to say "yeah nah it's all bs and there are clearly chaptic deterministic mechanisms going on at the heart of it."
I love it for fun.
Started reading the Feynman lectures. It’s pretty tough stuff lol. https://www.feynmanlectures.caltech.edu/III_01.html
Here's a nice (gentle) overview of the gauge groups of the standard model:
Assume I read college books in kinder garden and progressed logarythmically to the age between "lift with w/e" and "w/e it is, it's painful."
Is this a (hard copy) book I should spend my fiat mine wages on?
Oh hell yeah. Right here! 🙋♂️ 
Nuclear physics friend checking in...
Haha this makes me think that you could find this paper interesting

Found my old phy uni work this weekend. I used to be smart. 😂
My best group theory from A Beautiful Mind — The Best for the Group comes when everyone in the group does what's best for himself AND the group
Quite the worthwhile rabbit hole indeed. I went on a similar tangent at one point; that was more with Henri Poincaré, however, in his Science and Hypothesis. Funnily, the tangent more or less comprised a fairly related structured with early works of group representation.
