That does about cover it.

Today after I teach my own class I'm dropping by the class of a colleague to do a little guest lecture on science. This is a regretable necessity as my colleague's students seem to be laboring under the misconception that science is concerned with explaining tiny little idiosyncratic phenomena, rather than large general classes of things. Today I will do my best to disabuse them of this notion using, among other things, a class activity involving two students, two glasses, and one bottle of Drano. Stay tuned for the possible lawsuits.

In honor of today's impending discussion of science, however, I thought I'd just provide y'all with this classic illustration of the difference between scientists and regular people, courtesy of xkcd:



And do you know what the hell of it is? The scientist is gonna have to pull that lever at least a dozen more times just to be sure. Ah, the stupid things we do in the name of learning.
