That's right, a physicist is the political leader of a superpower! I just found that out; it has never been mentioned on PF before (says google). Apparently she's some sort of chemical physicist, or physical chemist. Here's a link to one of her papers, on gas phase dynamics, in J. Am. Chem. Soc. (1st page): http://pubs.acs.org/cgi-bin/abstract.cgi/jacsat/1988/110/i25/f_ja00233a012.pdf This is awesome!
