Yeah, actually I meant something like... mitigate, with respect to the link between power lines and cancer. As in, it was circumstantial; there was another unaccounted for cause.
Probability on an impact is fairly low. Still would be a consideration which probably results in building (initial) permanent settlements underground. Radiation is a bigger concern, since lethal doses are possible every time energy from an x class solar flare hits the lunar surface.

There's always risk. Every 100 years or so a rock big enough to do considerable damage gets through Earth's atmosphere. Every few years a storm big enough to do considerable damage hits a major population center. Hell, we live on a molten ball of rock with a crust that's only 30 or so miles thick. Tomorrow the east coast of the U.S. (where I live) could be wiped out by a tsunami.
Caves are a poor choice. Radiation levels in a cave are higher (naturally occuring background from the rock itself). Have to live in grass huts and never go out in the mid-day sun to minimize exposure to UV.
Turns out that any connection between power lines and increased cancer rates was always a false positive. In all cases, it was mitigated by some other cause, such as the community was getting it's water from an aquifer downstream from an old chemical dump. The initial research which made the connection, was falsified, and the scientist, well, he's not doing research any more.
There would be over 300 scientists involved in the project; but, not 300 directly running the project. Many of those would be ancillary, for example grad students and prof's at universities associated with the project, who look at the data and help make decisions wrt what to look at next.
Actually, they're not designed to look for life. They're mobile geology platforms. If they happened to find life, or evidence of life, that'd be the Holy Grail. There are future probes going up that will "look for life". Still, they've done a good job and we've learned a lot from them.
Ahhh, but we don't know this for certain. If the geological origin for oil ("abiogenic") theories are correct, then there's every reason to believe that there may, in fact, be some oil on Mars. Might explain some of the methane we see seeping from the surface.
It does suck, that's why I transfered to Physics. Found natural sciences to be more interesting and covered topics more broadly. Also, I found the natural science departments tended to be smaller, which meant you got more face time with a professor.
5. Awful Textbooks
Physics textbooks tend to be "direct" and full of equations at the upper level. Sometimes the books notation was different than the professors notation. Nature of the beast. I found lower level science texts were more engaging than engineering texts. Your mileage may vary. Of course, there's always the library, where you can usually find other books on the same topic. Another book might explain it in a way that makes more sense to you...
4. Professors are Rarely Encouraging
I found the professors in Physics were more engaging than those in Engineering. The departments had fewer students. Professors tended to be more "interesting." You got to spend more face time with the profs. As long as you were willing to do the work, they were happy to encourage you and would engage you in their work (as free labor, of course).
3. Dearth of Quality Counseling
The academic advisor's job is not to guarantee you find work after you graduate. Their job is to make sure you consistently work toward completion of a degree program that you chose. There's no guarantee that a job will be waiting for you when you get out. Again, I found the physics profs tended to be more interested in cultivating their students.
2. Other Disciplines Have Inflated Grades
OK, your wining because you have to work in a competative environment where you actually have to study the equivalent to rocket science; and you want to compare your grades to the Art major? We Physics majors thought you Engineering major's had it too easy. Does that make you feel better? You either enjoy what you study or your are in the wrong field and need to change majors. That's exactly what I did.
Some professors view undergraduate education as a type of natural selection, It is.
but their analogy is flawed. not it's not. If you can't hack it or don't like what your doing, you should be able to determine that as soon as possible; so, you can find something you are good at.
Many of the brightest students may struggle while mediocre scholars can earn top scores because they have a larger group of supportive friends to or more time to dedicate to studying. Then the bright student should have sought help. I never had trouble getting explanations from profs. Of course, I was a Physics major, which meant I wasn't competing with 100's of students, only 10's.
1. Every Assignment Feels the Same
Science and engineering use mathematics to describe the world. It only makes sense that math is a major component of the work required. Unfortunately, unlike literature where you can take the books home, you can't take the lab equipment home. But, that's why there are lab components to many undergrad science courses. It turns out, if you ask for time in a lab, and could provide some reasonable justification (I want to understand x better, is usually enough), you can get time in the lab... Again, I have to recommend science because the smaller class size means the resources aren't being stretched as far.
Look, undergraduate education in science or engineering is as much about teaching someone how to study or how to do research as it is about teaching fundamentals. Nothing is going to be handed to you; you have to be willing to do the work. You also have to be willing to make decisions (you are an adult now). If you don't like engineering, find something else.
"Now how did the machines know what Tasty Wheat tasted like, huh? Maybe they got it wrong. Maybe what I think Tasty Wheat tasted like actually tasted like, uh... oatmeal or tuna fish. That makes you wonder about a lot of things. You take chicken for example. Maybe they couldn't tell what to make chicken taste like which is why chicken tastes like everything!"

Actually you can prove cosmic rays cause memory errors. IBM did so in the 90's; there was mention of this (and a link) in the article. As memory cells become smaller they WILL become sensitive to ionizing radiation. Intel seems to think we will get there sometime in the next decade or so.
Kim Stanley Robinson suggested something like this in Red Mars. First bunch of people sent are highly motivated types who know they have no way to return. They are on their own, having only the supplies and equipment dropped ahead of time, and have to rely on their own abilities to survive.
One of our sales people who spends a lot of time in China explained it too me this way:
CD-R disks, in China, are heavily taxed. They're expensive, relative to the average income. Windows 98 fits on one CD. The typical Linux install requires several CD's (including all the packages). It's cheaper to pirate a copy of Windows; so, that's what they use.
The information is a little dated, but may still holds some truth.
You're not serious are you? What's on the surface of the Earth's crust (where we can reasonably reach it via mining) is a very very small amount compared to what's likely to be in the core. Using modern reactor designs, proper fuel reprocessing, breeder reactors, and tapping thorium, there's enough fuel for 10's of thousands of years without impacting the environment.
Vista does run on some older machines. It wouldn't work on my Athlon 2200+ based laptop because there wasnt' a Vista compatible driver for the video chip.
I needed a Vista machine, so I bought one. It's a dual core AMD TK-55 which runs at 1.8GHz. It has 2GB DDR2 memory and 256MB dedicated video RAM. Yes, it works, it's been reliable; but, it IS slow. Setting it up side-by-side with an equivalent Ubuntu or Windows XP machine and it looks bad. To me, speed matters. I can't sit around waiting for a program to compile or the machine to finish crunching numbers.
Is the S2000 a sports car. It's burning premium 93 octane, isn't it. OR at least that's what's recommended. That's how it's 11:1. If you want to run 86 octane "regular" unleaded gas, you can't go above 10:1 without doing other things to prevent pre-ignition... like radically backing off on the timing or leaving the intake valve open a little longer than normal. Either drops your efficiency. Backing off on the timing risks means the pressure wave is delayed till after peak compression, which is less than optimal and risks exhausting incompletely burned fuel. Using the intake valve trick effectively drops your compression ratio.

That would certainly add a new dimension to the presidency.

there are huge botnets in China. Just because the IP address was Chinese does not prove China is the origin of the attack.
