Actually, Robert didn't write that, he's quoting Paul Deema, so let's straighten THAT out first!

Second, you might be surprised to know that this is not universally held to be true!

"Really?" you might ask me. "Who, pray tell, would seriously entertain a probability that does not fall between zero and one inclusive? Surely some crackpot, right?"

And you'd be wrong.

For the Festschrift for Jean-Pierre Vigier, noted physicist and Nobel laureate Richard Feynman wrote an essay entitled "Negative Probability," where he does, in fact, defend as a quantum mechanical necessity the need for negative probabilities to exist.

It turns out that the constraint in quantum mechanics is merely that the sum of all the possible outcomes equals 1. So, you can have a probability of 1.5 and -0.5 for an event, and the quantum mechanical considerations will work out correctly. (This is another reason why I regard quantum mechanics as the physical equivalent of dividing by zero -- you can get any result you want, including mounting the well- known proof that 1 = 2.)

So, it is interesting that Feynman even contributed to the Festschrift, insofar as Feynman likes the Copenhagen Interpretation of Quantum Mechanics while Vigier spent his career defending the de Broglie-Bohm-Vigier approach to QM (the stochastic causal interpretation that points to a deterministic classical subquantum domain). But the reason he contributed is clear when you read his essay -- he knows that Vigier has a point that conventional QM leads to negative probabilities, so Feynman feels he's under compulsion to defend that concept. And so it goes.

In other words, there's no statement, be it ever so harmonious with mathematics, logic, and common sense, that a highly regarded Nobel laureate can't be found who will gladly trash it for all it's worth. Including the idea that probabilities ALWAYS lie between zero and one. You think like THAT, and you'll NEVER get a Nobel prize!
