I wasn't thinking either actually, but yeah, what I meant is: can the 3-body problem be solved if the movement of the three bodies is coplanar? (like, when the plane defined by the three bodies isn't rotating)

Is the three-body problem still unsolvable even when the three bodies are located in the same plane?

Dextercioby, my question had nothing to do with disentanglement and measurement. EDIT: How do you know that I'm a "he"? Well, I am, but you couldn't have known that.

For an electron in an arbitrary spin state, can an axis always be found along which the spin is 1/2 (as opposed to a superposition of 1/2 and -1/2 spins)? What about particles whose spin is 1 or greater? For example, for a spin 1 particle which is in an arbitrary spin state, can one always find...

So does that mean that when the acceleration is constant the charge radiates but the radiation doesn't go off to infinity, but rather stays with the charge (in the charge's field)? What if in your frame of reference the charge is undergoing constant DEceleration? Now the charge is doing work on...

Hm, I was sort of suspecting that... It's just that I read that electrons in a superconductive ring are accelerating and must radiate according to classical physics, and the reason they don't radiate is quantum mechanical. I guess that classically for the spinning sphere or ring to not radiate...

Imagine a charge (I'm talking about CLASSICAL charges, NOT electrons in an atom) which is orbiting amother much more massive charge. The charge will radiate, call the power it radiates p. Now imagine a charge spinning on it's axis (but not orbiting, just spinning), it will also radiate(we can...

LizardKing23, what are you smoking? I want some too! Or is this some kind of a joke? Do you even know the solution to the two body problem? Hint: it is reducible to a problem of one body moving in a central potential, and the solution of the one body problem involves calculus.

How is the fact that ALL accelerating charges radiate reconciled with the fact that the radiation reaction force is ZERO when the acceleration of the charge is CONSTANT?? Also, if you are accelerating, but the charge is NOT, do you see any radiation coming from the charge or not? Thanks

That's what I was thinking. But it's usually not stated explicitly that the states must be independent. Don't the states have to be orthogonal, not just linearly independent though?

I know I already posted this question, but it seems to have gotten "lost" among the other questions in the same thread. This is really confusing me now, so I'll ask it again. The pauli exclusion principle says that no two fermions can be in the same quantum state. But if we have three...

So does anyone know whether the neon atom is spherically symmetric or not?? I found the following statements on some chemistry exam on Google: The nitrogen atom, with its half occupied 2p orbitals, has a spherically symmetric electron distribution. Use the explicit expressions for the...

WOW! Neon atoms are PERFECTLY SPHERICALLY SYMMETRIC??! I have not seen this mentioned ANYWHERE. I mean, I've skimmed through advanced quantum mechanics books, I might have missed it, I don't know. Ok, so I guess the question is, why is the neon atom sph. symmetric in it's ground state? Is it...

Haha, I was afraid you'd say that! But seriously, Neon is typically pictured as having three perpendicular p orbitals. I assume that this somehow corresponds to reality. So, why are the p orbitals perpendicular?

Yes, of course! But when an atom (Neon for example) is in the GROUND state, are the three p orbitals perpendicular to each other, and if so, why? I was thinking that perpendicular p orbitals would be favorable because maybe they minimize electron-electron repulsion.
