It also filled a critical remaining gap in what physicists refer to as the Standard Model, the theory that governs physics at the microscopic scale. It accounts for the behavior of three out of nature's four fundamental forces - electromagnetism, the strong force and the weak force, which governs radioactive decay. Which brings us a few step forwards towards the answer of 42.

QED agrees with experiment to about 12 digits. QCD agrees (at low energies) to about 1 digit (10% accuracy). However, a lot of that is due to the fact that we can only do calculations in QCD to that level; if we could do them more accurately, QCD would probably agree better with experiment.

Well, they are less a particle than an electron in that you can observe an isolated electron, but not an isolated quark.

"High Energy" in QCD means anything higher than the QCD scale of a few hundred MeV ... so a "high energy interaction" is one in which the parties to the interaction exchange energies that are of the order of 1GeV or more. Certainly, all of the Standard Model breaks down at the gravitational scale, but that is so very much more energetic than the QCD scale that that's not what we're talking about as "high energy". We usually reserve "Planck Scale Physics" for those energies.

Not only does cellphone technology rely on satalites, but also on the precise atomic clocks contained with in them. And those atomic clocks rely on our quantum mechanical understanding of atoms. Thats not to say that this particular research directly led to our widespread cellphone usage, but its just an example of how much basic research affects our daily lives.
Now, every now and then pure mathematicians will come up with an obscure field that they will decalre as being unaplicable to anything ever ( see group theory). Then a few years later a group of physicsists will discover that it has a real application in physics. Then they will speculate wildly about the potential applications in an attempt to gain greater funding, while privately thinking that it has no possible use. Then some crazy engineer will discover some such use ( usually one the physicists never thought of) and whoila it has a real world benifit to all of mankind. The more tools we have to solve problems, the easier the problems become. The tools have a trickle down effect. More mathematical tools lead to more physics tools which lead to more engineering tools which lead to more solutions to our everyday problems.

I remember taking "Track B" with Politzer and Gomez back about that time, with class notes distributed on pink paper, brutal take-home quizzes on relativity, etc.
Politzer is a pretty good and patient prof, answering questions, explaining basic physics points, etc. although one time he did get annoyed at a cocky youngster (I don't think it was you - this was 26 years ago) slouched up in the front row.
Cocky youngster: "I don't see why you just don't use Stoke's Theorem."

As of the early 90s, he had done literally nothing of interest besides his teaching.
