A collection of some classic Lemmy memes for your enjoyment
Yeah, "spin" was a stupid thing to call it. We have a nice, hard definition of what "spin" is on a macro scale. Why take a complex property of matter that we don't have a name for, and give it the same name as a fairly common, easy-to-understand phenomenon? Extraordinarily smart people being idiots, honestly.
Imagine a woman in hot pants with thighs like a Robert Crumb dream woman.
I don't know if it helps with this problem though.
NoU Imagine a cactus eating a deer.
I recall a Richard Feynman video where the interviewer asks him to explain how magnets work.
His answer amounts to "I can't explain that to you because if I gave you an accurate answer it would be too technical for it to make sense to you, and if I simplified it to the extent that you could understand, it would no longer be a meaningful answer."
His point was that we don't understand the interaction between fundamental forces enough to say, if we were to try and answer the question accurately enough.
So, in one sense ICP was right that we don't know how magnets work. But also they were wrong that scientists be lying. They shouldn't have been pissed.
That interview answer always seemed like a cop-out to me. You could make a comparison to gravity to explain how magnetism "just is".
Title-Text: "Of these four forces, there's one we don't really understand." "Is it the weak force or the strong--" "It's gravity."
I expect Feynman’s answer, if he had a whiteboard and unlimited time, would’ve been to dive into Maxwell’s equations.
With that in mind, his answer makes complete sense. Good luck explaining coupled PDEs to people who aren’t mathy in a few sentences without visual aid. The analogy to the gravitational force isn’t on point; there’s a lot more to be said about how magnets tie to into E&M more broadly, compared to gravity.
Though you’re absolutely right that once you get deep enough into any topic in physics that the answer to “why?” inevitably becomes “it just be like that”.

Yeah, a proper answer would need to dive into how it relates to electricity for sure
I think OP's meme illustrates Feynman's point very well; there comes a stage where if the number of incorrect statements in your explanation outnumber the the correct ones, it's no longer a meaningful explanation.
A lot of Feynman quotes are ultimately just witty cop-outs IMO.
I guess they are, there's for sure something to that, but at the same time these quantum or relativistic phenomena really can't be described accurately in simple words
It's certainly unintuitive, but that makes sense; our intuition is formed from our experiences, and we have no experience with the domains that relativity and Quantum mechanics apply to.
Uuuh I have to remember that one
Whenever any of this comes up I remember that physics professor's speech on first day of quantum mechanics that got viral:
“Nobody understands quantum mechanics. The people who came up with it don't understand it. I will do my best so that by the end of this course you don't understand it either, and so you can got out to the world and spread our ignorance.”
Or something to that effect.
Quantum mechanics is illogical and stuff that happens makes no sense but can be recrcreated through experimentation....as long as you don't look at it.
The end
Quantum mechanics is extremely logical - we understand the math extremely well, and the math describes reality better than any other theory.
It is, however, not intuitive.
I was just being cheeky
It's perfectly logical, what happens makes sense, we just don't know key facts about what is actually happening.
How can you know that
Because it's part of reality, a foundational part of it even, it's logical basically by definition. If it wasn't, it would just mean our concept of logic is flawed.
Beyond that, we have perfectly logical and sensible descriptions for what is happening in quantum physics, the problem is just that we have more than one and don't know which is right.
What definition of "logical" are you using here?
Coherent and coming from sound reasoning
I'm so good at not understanding stuff. My time has come.
The Many Worlds Interpretation must be rejected because it makes sense and we've already agreed that Quantum Mechanics is not supposed to make sense.
Well put. I will never understand how Bohr managed to persuade so many scientists to commit themselves to not making sense.
I think the trick was to establish that disagreeing with the Copenhagen Interpretation makes you one of these idiots who can't comprehend Quantum Mechanics. Idiots like... Albert Einstein? Or... Erwin Schrödinger? You know, real morons.
Is more like a feeling
electrons be vibin
Imagine a mathematical concept that approximates a particle across a spherical plane. Now imagine a force emitted from this sphere in a field. Okay, we're ready to talk about why this is wrong, too.
Right-hand rule bitches!
