You're a Quantum Mechanic? Great, so what can you tell me about the mileage
on the new 99 Quantums? Are they better than the 98 models? Have they
solved the problem with the Tacyon (sp?) drive slippage?
Sorry about that, couldn't resist.
Thanks for correcting my over-simplification/misrepresentation of the
Uncertainty Principle. My physics is at a purely PBS documentary/Steven
Hawking's popular writings level. However, in my own defense, I'd like to
say that at least I don't misrepresent the weirder aspects of quantum
physics to suggest that we all "create our reality" or indulge in similar
wooly new-age thinking. I do confess that when people talk about the
"collapse of the wave function" I tend to picture a high brace failing
rather than any lab experiment. Like you say, it may not matter in a sea
kayak context, but it's fun. In a published essay, I once drew a parallel
between how the length of water waves determines what effect, if any, they
will have on a kayak, and the way the wavelength of electromagnetic
radiation determines whether it will or will not interact with small
particles. Hope I got that right.

Cheers,
Philip T.
