George M. Whitesides, a chemist by background, is Woodford L. and Ann A. Flowers University Professor@Harvard University. "I am bipedal," he adds, "and hope, soon, to grow large diaphanous wings that are reflective to space-based radar. I tag along with a group of graduate students and postdocs who study materials science, condensed-matter physics and chemistry, and biochemistry. In my spare time, I think about subjects such as the performance of musical instruments in extreme environments (for example, under water, in ultrahigh vacuum,@cryogenic temperatures and so on)."
