Night Class

Tuesdays and Wednesdays I have night class. Night class can be a bit of a drag because I have to travel back to school for a second time on those days. Plus the lectures are about 3 hours long, which is way longer than my attention span.

Last night was Psychology. It seems every unit has some kind of unethical experiment. Last night the lecture was about dreams and learning. Apparently Pavlov locked dogs in cages, starved them, and cut up their digestive tracts before teaching them to salivate when he rang a bell. Watson taught a little kid to be afraid of white fluffy things such as rabbits and Santa Claus beards by giving them a rabbit to play with then sneaking up from behind scaring the kid. The experiment ended when the kids mother stopped taking him to day care...

Here's a interesting article by Bruce Schneier that I saw. It is about identification cards and security. He makes a few good arguments against over stating the value of IDs. [Nevertheless, IDs have their (limited) uses].
