Consider yourself lucky it wasn't the other way around. I had really easy AP classes (except for maybe AP Spanish) which led to the development of some bad habits.
To put targeted data gathering in perspective: the detectors at the LHC will produce thousands of channels worth of data, at an interaction rate of 40 MHz. Conservative estimate: if we've got 8bit data in 1024 channels at 40 MHz, that's a raw datarate of ~40 TB/s.
The function of the trigger, as it's called, is to get that insane datarate down to something manageable. This is where the models come in. Physicists who are looking for certain events will run full simulations of collisions in the detector, and come up with a set of detector conditions. Then they present their requests to the trigger people, who will see if they can accommodate them.
The trigger system then processes the data while the accelerator runs. Most of the data gets ignored, but the interesting stuff gets flagged and saved.
(Note: I don't work for LHC, but I work for RHIC.)
The big losers would be researchers working on the U.S. team for ITER, the gigantic fusion reactor to be built in Cadarache, France (Science, 13 June, p. 1405). In December, Congress zeroed out the U.S.'s $149 million contribution to ITER this year. The Senate version of the supplemental included $55 million for fusion research, but the House bill doesn't mention the discipline. It also forbids DOE to spend any of the 2008 money on research until it has restored all the job cuts, meaning that ITER would have to make do with whatever is left.
Go talk to a professor about doing research. They would be the ones to know. Even as an undergrad, you might be able to draw a salary working on a grant project.
The truth is that the paradigms keep on shifting in a revolutionary way, like they always do. Indeed, I believe that the fields of physics and computer science are ripe for a few disruptive changes of their own in the not too distant future.
Uh, doesn't this jibe with what I said? Paradigms can't shift if people are locked into them.
Sorry, what do weapons have to do with scientific revolutions?
Wernher von Braun and J. Robert Oppenheimer would be my examples of weapons scientists, but scientists can be pacifists, too. Joseph Rotblat quit the Manhattan project, and later received a Nobel for his efforts to encourage disarmament. Linus Pauling had a change of heart after WWII and spoke out against nuclear testing, among other things. And I think that if you talk to people today, many will express reservations about working for the military-industrial complex.
Regarding world views, Einstein had the "right" world view for the theories of relativity. However, his world view could not accommodate quantum mechanics. Despite facilitating a paradigm shift in one area of theory, Einstein was unable to accept a different shift in a different area.
I disagree that "academics are not open to new ideas". The problem these days is that there are very few "disruptive" ideas. There are few new theories worth exploring; we are mostly nailing down the outer reaches of existing ones, and discovering that what we have got works extremely well. Every scientist wants to push the envelope. After all, scientists are rewarded with Nobel prizes for radically shifting our understanding of nature.
The Inquirer (yeah, I know, hold your nose) has more believable numbers: 40% yield, $5000 per wafer, 40 good dice. So $125/die. Add NRE, testing, etc.
When there's so many stream processors on a chip, it's going to be big, no doubt. That's why a 55nm version is coming. Cell also underwent a die shrink shortly after it came out.
I've been itching to upgrade, but I guess I'll be waiting some more.
I'm also from Castro Valley and I endorse this post. San Ramon is where rich people live in suburban sprawl, and where Chevron is headquartered.
There does seem to be quite a bit of enthusiasm for ranching in this area, though. It ranges from the guys with "Cowboy Up" pasted on their trucks to the folks who actually own ranchland and spend their free time on the land. There's also the annual Rowell Ranch Rodeo Parade.
According to the preliminary design report, the calorimeter is 8.5 radiation lengths deep, with 1.5 in the tracker. I forget my shower mechanics but 10 rad lengths seems like enough. The design goal is 20% accuracy for a high-energy range, and 10% and 6% at progressively lower energies.
This stuff makes me feel lucky that I work with lots of lead glass and PMTs.
Well, yeah, I went from the GP's position (Christian, evolution) to agnosticism.
My problem with your position is that you accept the Bible as it is, despite it being touched by so many human hands throughout history. You accuse the GP of picking and choosing, but isn't that exactly what the Council of Nicaea did?
I understand that there are apologetics regarding the provenance of the Bible, but like most apologetics they're based on faith.
Well, anyway, I'm not looking for an argument, just wanted to throw that out there.
That's really one of the most disturbing things about Bush's view of presidential power. Why don't they do things according to the law, especially when Congress has made it so easy? They seem to pick and choose which laws apply to them.
It's not surprising that McCain will follow suit. McCain lost my respect when he started flip-flopping like a fish out of water. Now it seems every day brings another reason not to trust him.
There's a 60T pulsed magnet at LANL. "Power comes from a pulsed power infrastructure which includes a 1.43 gigawatt motor generator and five 64 megawatt power supplies. The 1200-ton motor generator sits on a 4800-short ton (4350 t) inertia block which rests on 60 springs to minimize earth tremors."

Word. There's a lot of stuff I wish I had read earlier in life, when I still had time to read, and to dream.
As long as there's no Kenny G, the kids will survive OK.
Reading the paper, I'm not so sure this is useful for HEP. In HEP, you are not interested in the number of photons, but rather their energy.
Could you elaborate on the shortcomings?

New theories must exceed old ones in their explanatory power. That should be self evident.
No, not really.

Also, I admire your bold use of selective quoting. Way to ignore the rest of my paragraph; I used the construction "post-Kuhn" for a reason.
;)
There are plenty of people who disagree with you.

We live in a post-Kuhn era, where the phrase "paradigm shift" is cliché. Scientists are well acquainted with his ideas, whether explicitly or implicitly. The last thing we need is a bunch of people telling us that we're locked into our paradigms, because it's simply not true. When the LHC starts up, everyone is hoping that new physics will be found, because accumulating more data to reinforce existing theories is not terribly exciting.

According to the last RoHS-is-stupid thread I read on Usenet, yes. Conformal coatings make rework messy, though.

They're treated with "quantum tunneling".

There's a TIE Fighter Total Conversion that combines TIE Fighter with the XWA engine. I haven't tried it, because I still haven't finished XWA!
That site also has ship model upgrades, it seems.

I'm glad that my tax dollars are being spent on something this badass. Now if I could write a proposal to get some time on this equipment...

And they're building a 100T edition.
