What PZ Myers said:
When anyone other than a particle physicist talks about “quantum”, it is almost always a magic word used to project a pseudoscientific aura onto sheer raving lunacy. “Quantum” as a prefix is almost universally used to signify that the noun it modifies is about to be made crazy stupid.
So simple, even a biologist gets it. 😉
Unless it’s “Quantum of Solace.” In which case we sit down for two hours with a bowl of popcorn. 😉
