Exactly. The problem is not that there aren't good textbooks, but the teachers who only buy the newest shiniest crap. But when a teacher is incompetent then the book is the least of the problems.
I whole-heartedly agree. I was under the impression that an AP calculus class is designed to prepare students for the AP exam, which, if passed, allows students to receive credit for, and thus skip, some or all of freshman calculus. IMHO, if it's not working that way, the system is broken.
I'm just waiting for the day when a person's gender/ethnicity/religion/you-name-it... is no longer news. As a Fedora user, I really give a damn if the project leader is male, female, black, white, gay, straight, Mormon, Scientologist, or whatever. I just want to know that he or she is competent.
My principal from 45 years ago is not only still alive, he's one of 500+ members of the Facebook group for my elementary school. Not only was he principled, but he was (and presumably still is) a helluva nice guy.
Whatever you think..taxes should not be used for behavioral manipulations.
Taxes are for funding the govt services we all need...that should be it...period.
While I disagree with this, I don't think it's an unreasonable position. On the other hand, I've yet to see a "fiscally convervative" politician actually stick to this position when deciding how our tax moneys should be spent.
I never worked with a laser heating system, but the idea is to use a frequency to which the diamonds are transparent. The quantity of test material within the cell is small enough that the total amount of heat absorbed by the test material is extremely small.
Back when I was in grad school, high-end diamond anvil cells were typically achieving pressures on the order of 1 Mbar; so 140 GPa certainly sounds reasonable. Laser heating should enable one to get to 2200 deg C and beyond quite easily. I only got to play with our cell at room temperature.
How much experience do you need, beyond an understanding of K&R syntax, to be an effective C programmer?
Very little. I'm certainly an effective C programmer; I can write programs that do what I need to do. The important question to ask would be, am I a good C programmer? I'll plead the 5th on that one.
As an undergrad back in the mid 1970s, I remember recording lectures (biology and/or organic chemistry and/or biochemistry, I don't recall which), but found I never listened to the recordings. As a professor, I never minded being recorded, and wondered if students actually listened to the recordings.
If a student's goal is learning, he or she will do it whether or not they cheat on homework. Homework, like teaching, is designed to facilitate learning, Exams are designed to measure learning. If a student can learn without doing homework, I'm ok with that. If a student can learn totally on their own without attending class, I'm ok with that. If a properly-prepared student can't learn even after attending class (and paying attention) and doing, or making a reasonable attempt at the homework, then I've failed as a teacher.
I never worried about students copying homework from one another. The proportion of a student's grade that came from homework was typically low enough that wouldn't have mattered if every student in the class turned in an identical assignment. However, I'd often use multiple versions of exams; especially when teaching in classrooms where students were seated close together. Surprisingly, when offered a choice between multiple choice exams (with no partial credit) and work-the-problem exams where partial credit was a possibility, most classes opted for multiple choice, even after I warned them that I've probably made every common mistake they're likely to make, so that my wrong answers would often look reasonable. Overall, grades on multiple choice exams seemed to be lower by about half a letter grade.

Not all calculus classes are created equal.

despite having been in honors and AP math during high school, I was totally unprepared for college calculus.
Huh? My AP math was calculus. Perhaps that's changed in the last 40 years.
Look again at the video - it's LXDE!
The scary thing is, I remember those days well. I may even have a few old Apple ][ floppies lying around somewhere
I was going to ask the same thing - fortunately, I searched through all previous responses before posing the question.

Well, guess I'll never work for you.

You made up pi? I thought it had a long history as the ratio of a circle's circumference to its diameter.
I agree: a distinction between legal unions and marriage is the way to go.

Performing a linear extrapolation of the sales data, we see that sales of desktop PCs drop to zero by 2028.

I disagree with the claim that Walmart's fake Dr. Pepper tastes the same as the real thing. But try both, side by side, and decide for yourself.

That's done by flooding the area around the cell with an inert gas.

If you wanted a vocational degree, you should have gone to a vo-tech school

d integration should become practical when 3d cooling (channels? pipes? something else?)
The obvious answer is diamond. Semiconduction and high thermal conductivity.
