Then, since Solo shot first, he was a fine duelist. This reconciles the argument: he can be a good guy AND shoot first. Solo did not _intend_ to shoot first, but while reposting his instincts made him the fastest.

A Krav Maga gun disarm involves twisting the body while redirecting the shot. Grabbing the gun isn't supposed to prevent the gun from firing, it's supposed to prevent the shot from killing you. In a real life situation when someone's got a gun to your head you probably don't have time to think about the gun's mechanics.

Well thats why you're thinking about it ahead of time. I distinctly recall the instructors commenting they'd rather face an idiot who gets too close to you with a gun than an idiot who gets too close to you with a knife, the knife will still cut you if you grab it. They also suggested you comply with anyone who has a weapon unless you have good reason to think they'll kill you anyway. I Really should take Krav up aga…

Yeah, I'm only a yellow belt at my school (Krav Maga Canada has a belt system even though the international org. doesn't) so we haven't gotten into weapon disarms much yet, but I think the general idea is it's easier to give up your wallet than successfully perform a gun disarm or redirect a knife.

Either way, it's a hell of a work out.

Hah, this is a trick question; the nucleus doesn't have electrons. And if it blows up, you don't bury the survivors.

Hah, this is a trick question; the nucleus doesn't have electrons. Well, technically, in an s-orbital there is a substantial, non-zero chance of the electron being inside the nucleus.

Not true, you may have been thrown off by the fact that s orbitals are generally shown as spheres; but the radial extent (probability amplitude) of the wave function goes to zero for small radii, for all s orbitals, see http://www.chem.umass.edu/people/botch/Chem121F06/Chapters/C....

A classically-behaving point particle with the same charge as an electron would drop into the nucleus, but the wave nature of real electrons forbids it. Due to the uncertainty prinicple, there is a nonzero chance of finding the electron in the nucleus, but to say it is substantial is false.
