I'll get back to symmetry tomorrow, but I'll do an aside today, spurred by the Google doodle in honor of what would have been Rosalind Franklin's 93rd birthday. I've peviously noted how important she was in the discovery of the structure of DNA. If she had not sadly passed away at a very young age, she surely should have been considered as part of the 1968 Nobel Prize. Last year Wendy Staples of the Quirky Cookie made a lot of science and women-scientist themed cookies for the launch party of the ScienceGrrl Calendar at the London Science Museum. ScienceGrrl is a British organization to promote science education, particularly to young girls. Anyway, here we see cookies of LEGO versions of Rosalind Franklin and Hedy Lamarr (best known for her movie career, but she also developed a radio frequency hopping technique that formed the basis for much of today's wireless technology). BTW, you really should go see all of the cookies. They're really cool, and I'm sure were perfect for a science themed event.
