Yep, what lubuntu said.
I'm a postdoc right now, and I love my work (hard as it is, sometimes). The lifestyle isn't for everyone, admittedly, though; just make sure you know what you're getting into.
Also, that prof. writes as if the tenure track is the only thing you can do with a physics...
My advice: follow your passions, but keep an open mind. You're young - you might love theoretical physics now, but you might find it's very different from what you think it is after studying for a while (I did). Same goes for engineering.
You should try looking at what professionals in these...
The difference between any field (including the Higgs Field; others would be the electromagnetic field, strong field, etc.) and the aether is that fields are Lorentz invariant, meaning they can accommodate special relativity theory. The "aether" is Galilean invariant, and can't accommodate...
Well, you hit the nail on the head. All neutrinos are left handed (and anti-neutrinos right handed) only in the approximation mass=0. Now that we know they have mass, this rule simply isn't true any more (that is, it's possible to define a reference frame where neutrinos are right-handed).
The difference is caused by the fact that there is an additional Feynman diagram in Bhabha scattering. (The electron process can occur by scattering OR pair annihilation/production, whereas the muon process can only occur by the latter.)
This gives a scattering amplitude (in terms of the...
vanesch is right. 3-jet events are the first and strongest evidence for the existence of gluons, but certainly aren't the only evidence. Validation of the quark-gluon (DGLAP) evolution equations in multiple high-energy phenomena (to at least 2nd order in perturbative QCD) is pretty solid...
Never mind - figured it out! (Sifting through the 1977 paper by Altarelli/Parisi, Peskin & Schroeder's Field Theory, and the 3-gluon vertex Feynman rule eventually confessed the right answer.)
Calibration's a tricky subject - not easy to explain on a forum. There's a lot of good books out there; Leo's book has a few chapters on PMT/scintillation counters with a how-to approach; I'd recommend it.

JLab was originally made strictly as an electromagnetic probe of nucleons and nuclei, but their mission has expanded a bit. It's a very tricky experiment; it will take something like a year of running time in one of the 3 research halls, if I recall correctly.
Layman's description of the...
It is kind of strange. Truth is, it's still basically a mystery where the masses of fundamental particles come from. So far, they are just input parameters for the Standard Model.
"All of the above" would be an accurate answer.
As for where these basic constituents derive their masses, well, we believe it's through interaction with the Higgs field. LHC experiments in the coming years will (hopefully) shed some light on that issue.
