“Many Navajo people have died of kidney failure and cancer, conditions linked to uranium contamination. And new research from the CDC shows uranium in babies born now.”
Solar panels and batteries require the damaging mining of all sorts of rare and/or nasty materials. This kills a lot of people, although predominantly in other countries nowadays. It's an argument that could be applied to nearly any mineral resource, and is more of an indictment of unsafe mining practices and capitalist exploitation. If we allowed practical research on breeder reactors, the need for uranium mining would nearly vanish.
I would guess they can "force" him to no longer teach that class, even if they can not dismiss him.
I don't think its bad that the university has the final say in what and to a certain degree how certain elements of the ciricullum are taught. It's not hard to imagine how a bad math course can very seriously compromise the students ability to follow other classes.
Not to say that this applies to this case, the professor proably made a good and ethical choice in class materials and is pressured for other reasons.
Strang's textbook is fantastic. One of the rare cases in college where I actually enjoyed reading a textbook. His lectures are available for free on YouTube as well, and I can't recommend them enough!
Yes, it is opposite in grad school. Recessions bring U.S. students. In a booming economy, qualified students take high-paying jobs. In a recession, they ride it out in grad school. (I only have anecdotal evidence for this claim.)
I'm not exactly sure what your asking, but basically randomness in returns decreases as you increase the sampling rate (i.e. annual returns are more normal than say minutely returns). This is due basically to the fact that the more activity happens between measurements. (I could be misunderstanding your question.) High frequency measurements of prices often exhibit regularities that result from the trading mechanism e.g. bid-ask bounce.
