Re: Recommend ME a game (Merged:Several Similar Threads)

Thanks! I'll see if I can get Soldat to run on a virtual machine. In case it doesn't work out, does anyone else have suggestions? Large-scale strategy games sort of turn me off, I guess. I hope I don't sound whiny and picky.

Re: Recommend ME a game (Merged:Several Similar Threads)

My brother and I are looking for a game to play with each other over the Internet, and I was wondering if any of you could recommend one. It would have to run on Windows XP and an Intel Mac, which probably limits the selection considerably. We would prefer something like Myst 1-4, puzzle games where...

Any feedback at all would be pretty useful, really. Also in the "does this seem reasonable" vein, I have this equation for the momentum transfer in the case of two identical disks moving in opposite directions at equal speed: A = k * (m*R*(sin θ)*(ω 1 +ω 2 + x•P) / ((sin θ) - k) A: magnitu...

Point masses

I'm under the impression that as far as anybody knows, pretty much all particles are point masses. So, how can particles fail to be black holes? It seems like anything as heavy as a tauon should have an event horizon even after you say "Well, we can't know its position for sure."

Yeah. So... what you're saying is that the angular momentum of one thing can't be directly turned into the other thing's angular momentum?

If so, how can one turn that into a more specific thing that can be used to predict what will happen?

Re: Impulses and collisions

Oh, gotcha.

But even frictionless, angular momentum can be transferred. If I have a rod spinning about its center of mass, then if it hits a ball moving straight towards the axis, it gives the ball angular momentum by hitting it on a course that is no longer straight through the axis. Right?

Why should there be a unique solution? There isn't one for point particles: you have to know the angle of scattering of one of the particles in order to determine the rest of the variables.

Something like incoming angle equals outgoing angle is a consequence of the conservation laws, so I doubt that's it.
