Wiedemann-Franz Law: Physicists break 150-year-old empirical laws of physics
ScienceDaily (July 20, 2011) — A violation of one of the oldest empirical laws of physics has been observed by scientists at the University of Bristol. Their experiments on purple bronze, a metal with unique one-dimensional electronic properties, indicate that it breaks the Wiedemann-Franz Law. This historic discovery is described in a paper published July 20 in Nature Communications.

New fundamental discoveries are being made in physics every day! Not that we'll be covering the Wiedemann-Franz Law in class, but it's still fascinating when these kinds of discoveries are made. 150 years is a LONG time in science!

Video Classics: Eureka, ep.1
Is Harvard Worth It? | Mother Jones
What's the value of a college education? Quite a bit, if the wage premium for college grads means anything. But maybe it doesn't. After all, smart kids go to college, and smart kids are going to earn more regardless. Maybe college doesn't have any independent effect at all.This has been my experience as well. It is far more important that you do as well as you can wherever you are, than that you be at the most exclusive possible school. Find the school that fits you - and your budget. Your future employers* are smart enough to look beyond the name on your diploma.
....
David Leonhardt summarizes:....Once the two economists added these new variables, the earnings difference [of elite universities] disappeared. In fact, it went away merely by including the colleges that students had applied to — and not taking into account whether they were accepted. A student with a 1,400 SAT score who went to Penn State but applied to Penn earned as much, on average, as a student with a 1,400 who went to Penn.
“Even applying to a school, even if you get rejected, says a lot about you,” Mr. Krueger told me. He points out that the average SAT score at the most selective college students apply to turns out to be a better predictor of their earnings than the average SAT score at the college they attended.
For what it's worth, then, high school seniors probably shouldn't worry quite as much about which university they attend as they do. If you're good enough to get into Harvard, you'll probably do just as well if you end up going to the University of Michigan instead.
*or law schools, or med schools, or graduate schools, etc.
