Fair enough. Not a great article, but I would love to highjack the discussion toward the question of why we have "weed out" courses in the sciences? The incentive system for science programs seems to be "increase our reputation by maximizing the percentage of graduates accepted at top PhD programs." So, the intent is to keep the number of science graduates to an absolute minimum, at least until it is time to write an op-ed piece decrying the lack of math and science literacy in the population. Does anyone have any thoughts on how to reconcile getting the small percentage of top students ready for careers in research and academia without the necessity of culling non-gifted students that find it interesting?
