The Ball State Kerfuffle
Posted by jrosenhouse on May 22, 2013 Eric Hedin, an assistant professor of physics at Ball State University, has come under fire for an honors course called, “Boundaries of Science.” The problem: the course appears to be little more than thinly veiled Christian evangelism. From The USA Today: “BSU appears to offer a class that preaches religion, yet gives students honors science…

“Science literacy is a vaccine against the charlatans of the world that would exploit your ignorance.” -Neil deGrasse Tyson Well, I guess it’s that season again. The charlatan who claims to have invented a cold fusion device — the same device whose flaws were exposed here two years ago — has just held an “independent…
American Physicists and the Under-rating of Experiments
Posted by Chad Orzel on May 21, 2013 At Scientific American’s blog network, Ashutosh Jogalekar muses about the “greatest American physicist”, eventually voting for Josiah Willard Gibbs, one of the pioneers of statistical mechanics. As both times I took StatMech (as an undergrad and in grad school), it was at 8:30 in the morning, I retain almost no memory of the subject, and…
A Lesson in Applied Probability
Posted by jrosenhouse on May 21, 2013 Nate Silver provides the antidote to some dubious statistical reasoning on the part of certain conservatives. He was replying in particular to this column from Peggy Noonan. A column, mind you, that opens with, “We are in the midst of the worst Washington scandal since Watergate.” Goodness! Then she presents evidence like this: The second…

Messier Monday: A Hyper-Smooth Globular Cluster, M5
Posted by Ethan on May 20, 2013 
“The Milky Way is nothing else but a mass of innumerable stars planted together in clusters.” -Galileo Galilei Welcome back to another Messier Monday here on Starts With a Bang! With 110 deep-sky objects making it up, the Messier Catalogue is the first comprehensive, accurate catalogue of faint (but not too faint) fixtures in the night sky. Each object…
“Einstein’s Greatest Blunder” was REALLY a blunder!
Posted by Ethan on May 18, 2013 
“Anyone who has never made a mistake has never tried anything new.” -Albert Einstein Back when Einstein first proposed his theory of General Relativity, his revolutionary picture of the Universe was met with a mix of curiosity, awe, and intense skepticism. It isn’t every day that your most cherished of all physical theories — the…
Simulating a Pendulum
Posted by Chad Orzel on May 16, 2013 
There’s a famous story about Richard Feynman at Cornell suffering from the science equivalent of writer’s block, after WWII. He was depressed and feeling like everything he did was pointless, until one day he spotted a student throwing a plate up in the air in the cafeteria. As the plate spun, it wobbled, and the…
Outer Planets’ Stormy Weather: All on the Surface
Posted by Weizmann Science Writer on May 16, 2013 Have you complained about the weather recently? On the gas giants at the edges of our solar system, Uranus and Neptune, hurricane-like storm systems as big around as Earth blow 1000 km/h winds for years on end. Voyager II image of Neptune, showing storm features. Image: NASA But wait…What exactly constitutes weather on a giant…
