Scientist at work

I’m a scientist with a doctorate in astrophysics on the evolution of white dwarf stars, so I can’t help but be bothered when people, especially public figures, hold ridiculous beliefs (e.g. astrology, homeopathy, telepathy) that deny or denigrate science. My heroes include Einstein, Newton, Feynman, Gandhi, Mandela, Bob Dylan, Bob Marley and several prior Bolt Beranek and Newman (BBN) colleagues.
