GAT_00: According to QM, there is a non-zero chance that you can run full speed into a door and go straight through it as if it didn't exist. It is unlikely, but given enough attempts you should be able to accomplish it.
GAT_00: Philbb: nmrsnr: The only way that makes sense as an introduction to QM is if he had immediately afterwards said "Confused? Vaguely frightened? Welcome to the standard state of mind one feels when studying Quantum Mechanics." Otherwise, WTF?That's pretty much what I got from it. "Nothing you've seen or heard so far makes any sense at all in the world that you have always known. Quantum Mechanics is like that."If QM makes sense to you, then something is wrong with you.According to QM, there is a non-zero chance that you can run full speed into a door and go straight through it as if it didn't exist. It is unlikely, but given enough attempts you should be able to accomplish it.
bighairyguy: A combination of strangeness and charm.
Jim_Callahan: Man, and my students thought I was a less than usually boring lecturer just because I tend to curse like a sailor every time I stop paying attention to something I've prepared in advance.This guy really goes all out.nmrsnr: No, QM says that if you run at the wall enough times you will appear on the other side of the wall because you really were there all along and that makes no sense, and is completely incapable of being explained classically.Actually, QM pretty much says this doesn't happen, as on macro scales the math collapses into Newtonian mechanics.There's really nothing that odd about it, things pretty much always behave somewhat differently in different length and time regimes than in ours. Even in classical mechanics initial approximations such as, say, newton's theory of projectile impact depth will be turned weird if you do something smartass like fire your projectile in an incompressible fluid, and the theory of gravitational acceleration goes right to shiat if you test it in a fluid of sufficient density and viscosity for resistance to be a major factor. everything's an approximation for its regime, ain't no total rules for all situations unless you want to burn up a lot of goddamned chalk on that chalk-board.//Fluid dynamics was the original "goddammit, none of this makes any sense" example of science being weird for the layman. That doesn't actually mean it doesn't make any sense if you're used to it. For bonus points, the Bessel functions you see all the time in the basic description of the H atom in intro QM? Original developed to solve a fluids problem.//Not that QM, or fluid dynamics for that matter, isn't cool as all hell. Its reputation for being a mind-fark is kinda undeserved grandstanding by science students that want to feel special rather than something truly beyond the grasp of mere mortals, though. I mean, the math can be a pain to the average english major, but a bit of pounding and you can get the core concepts in the ...
daniellynn's real dad: Oddly enough, this is not dissimilar to my Quantum Physics professor's last lecture. He got naked, started yelling at walls, then ran into every other occupied lecture theatre before being lead away./not an Ivy League school//still CSB
