Organic Chemistry. It's like playing Tinkertoys, except that if you do it wrong, you could blow up the lab. I also liked my freshman seminar, Origins of Modern Science. It was all about how the philosophy of modern science, like empiricism, came about, taught via the story of how we figured out how to account for the movement of the planets.

Intro to Religion: studying religion well asks you to open up your mind to levels of subtlety that I'd never really explored in my high school classes. It felt like I was learning a whole new way of thinking, and it was compelling and fun, and it wound up as my major. Ecosystems Ecology: taught by the biggest rock star of a professor Carleton has ever seen. In class, he was organized, thoughtful, and explained complex science in terms that even the religion majors understood. The labs took advantage of our own local ecosystem (the Arb), which brought the concepts home.

Views of Reality, my freshman seminar, changed the way I view culture and the development of ideas. I see the world in a new light and think in different ways because of that class.
