He was not talking about colliding atoms hard enough to wiggle electrons to boil water.

This guy wrote me, quoting the Albert Einstein quote I have on Things People Said and took exception to it. But, um...I don't get it. What the hell is he talking about?

The only place atoms are collided together are in nuclear accelerators and atom bombs. And only in accelerators is the first part of his statement even half true. They slam atoms together in an accelerator at high speeds and cause fusion (well, depending on what atoms they're using and what they're attempting to do. Light atoms slammed together generally fuse. Heavy ones might fuse temporarily, but will eventually decay and split). Of course, the energy put into it is way more than what you get out of it, so it's not very good for anything other than scientific study. They slam "atoms" together in a nuclear bomb too, but only in a most literal sense. An atom bomb works by bringing a quantity of fissible material to critical mass very rapidly. They do that by putting a sphere of conventional explosives around the core of plutonium or enriched uranium. When the conventional explosives go off, the directed force causes the core to be forced together, causing a runaway fission reaction and a great big explosion. Anyway, in no case does this have anything to do with wiggling electrons. In the first case, the electrons are long gone by the time the atoms are accelerated. They use ions stripped of their electrons, not complete atoms. In the second case, the electrons don't do anything at all. If anything, they get in the way. What he probably THINKS he's thinking about is how fission reactors work. In a fission reactor, rods of Uranium are collected together, interspersed with rods of a dense, neutron absorbing substance that keeps the Uranium from undergoing fission. The whole thing is underwater. They slowly remove the control rods, and the uranium starts to undergo a slow, steady fission chain reaction. This causes a steady release of heat, which in turn heats the water, which in turn produces steam, which in turn turns a turbine, which in turn creates electricity. The whole contraption is really just a high-tech steam engine. But again, it's got nothing to do with electrons at all. And anyway, as you and I both know, Einstein's statement is wrong, as the atom *is* split at will. Otherwise we wouldn't have fission reactors or nuclear bombs. -- Dave |
