Here's a brief essay by Martin Schwartz, published in the Journal of Cell Science. The title really says it all: The Importance of Stupidity in Scientific Research. There's not much more that I can say, except that I think Dr. Schwartz pretty much hits it right on the head with this one! It's a short, one-page essay about the importance of recognizing the human-ness of science and cultivating and fostering the proper attitude towards uncertainty and the unknown in research. Pretty good stuff, with lots of good advice for both Teachers and Students.
