And the quantum world keeps on getting stranger and stranger

The whole quantum spirituality thing really annoys me as well.

What gets me is that if all that spiritual stuff actually worked like quantum mechanics, nobody would believe in it. There are no analogies for quantum behavior.

:laugh: I've never thought of it that way.

This is why I always dread trying to explain aspects of quantum theory to "some" people.

Yeah, I've definitely given up trying to explain any of it to anyone that doesn't have a really open mind and is willing to do a lot of reading. I really believe that QM just isn't compatible with the way humans think, so the only tools we have for understanding it are mathematical. On top of that it takes the math and requires you to use it wrong. Nobody on this planet would ever conceive of mapping complex linear algebra onto a form of mechanics like that in a million years. [edit]wrong is probably not the correct word there. Unnaturally is probably better.[/edit]

You go Stan! ;P

Just like anything above three dimensions.

Thanks Pete, new sig material.

A SINGLE-PHOTON TURNSTILE, a device in which photons are emitted one at a time under controlled circumstances, has been created by a team of scientists from Stanford (US), Hamamatsu Photonics (Japan), and NTT (Japan). Essentially the researchers use the quantization of electrical conductance to produce a quantization of photon emission. They put together a quantum well (the frontier between two thin semiconductor layers) containing a single electron (other electrons are dissuaded from entering because of a "Coulomb blockade" effect) with a quantum well containing a lone (comparably Coulomb blockaded) hole, and then cycle the voltage across the whole stack of layers in such a way that the lone electron and lone hole meet, mate, and make a lone photon. The resulting device, which operates at mK temperatures, is typically a tiny post some 700 nm tall and with a diameter of 200-1000 nm. (J. Kim et al., Nature, 11 February 1999.)

Only when we try to think of it on the same terms as 3 spacial dimensions. We deal with plenty of higher dimensional spaces fairly regularly without realizing it, and the mathematics is the same. Quantum mechanics goes something along the lines of, take an absurdly high dimensional space and then do some weird kind of rotation operation on it and see how the lengths of everything changed. We'll call that a position measurement. Do the same thing with a related rotation and that's a measurement in a different direction. Do a really strangely weird rotation and we'll call that a momentum measurement. Take those operations and stick them together like it makes sense to do so and bam, you have energy. Make them into a differential equation and now you have motion. It all manages to be consistent, and make the most accurate predictions of any theory we've come up with, but absolutely nobody has any idea why any of it would be in the first place.

That's one cool sig.

I wanted to edit it and higlight the bits about the lone electron and hole mating and producing a tiny post, but I can't click on it without following the link. But I couldn't.
