- What is classical in a cloud chamber (in which by the way, no one has ever
- seen a W!) is not the charged particle but the droplets which condense on the
- ionized nucleation sites. The W itself is behaving quite nonclassically.
-
- Meanwhile, if you happened to have a low energy neutrino in a bottle (bound
- in some kind of neutrino atom or something) and wanted to study its classical
- behavior, you would be able to do it by exciting it to a sufficiently high
- energy level. Thus it is a particle in the classical limit, not a wave.

- Even in the Higgs model the mass of the electron is not entirely from
- the Higgs-electron interaction, is it? Up to a few percent of the mass
- still comes from radiative effects (depending on what cutoff mass you use
- when you renormalize). And (as Matt Austern is always pointing out every time
- I mention Higgses, the total body of evidence for the Higgs is so slim and
- indirect that, IMHO, it would not be fair to take potshots at an outsider
- for not knowing about them, yet.
