I was an undergraduate once and had to take some non-science related courses. In the seven such courses I took, I wrote a lot of essays, some of which I think would make good reading material. I'll start editing and posting some of the ones I think are the best (or excerpts from them). If you're here for computational biology, please excuse the interruption.
Also, I'll preface these by saying I don't necessarily agree with all the opinions in these essays. Opinions can be such capricious little devils.
