Calling them "three outstanding individuals" who will help him tackle some tough problems, President Obama on Monday morning nominated:
-- Gina McCarthy, currently an assistant administrator at the Environmental Protection Agency, to lead that agency. She would succeed the departed Lisa Jackson.

So, last tuesday I explained why (in my humble opinion) the pop diva Beyoncé provided us with a nice example of overlap between Science and Art. In particular, I was thinking that, even though Beyoncé is not producing sonnets that will be read in 1000 years, she provides an example of a dedication to craft and excellence that is what scientists (at their best) also expect from themselves (minus the thumping beats — bummer).
