So, what is quantum mechanics? Even though it was discovered by physicists, it's not a physical theory in the same sense as electromagnetism or general relativity. In the usual "hierarchy of sciences" -- with biology at the top, then chemistry, then physics, then math -- quantum mechanics sits at a level between math and physics that I don't know a good name for. Basically, quantum mechanics is the operating system that other physical theories run on as application software (with the exception of general relativity, which hasn't yet been successfully ported to this particular OS). There's even a word for taking a physical theory and porting it to this OS: "to quantize."


This is the best description I've ever seen of quantum probabilities. Its also a fun read! (via A.C.)

That's a great quote.

It reminds me of a philosophical question I have: If energy weren't quantized, would the first law of thermodynamics suffer from rounding error?

I also like this talk of his (at least, once you get past the "NP-completeness for physicists" bit at the beginning).

Personally, I think his hierarchy is upside down.
