I'm an Astrophysicist at the
Harvard-Smithsonian Center for Astrophysics (CfA).
A FEW GOOD QUOTATIONS.
SCIENCE EDUCATION , including my 2002 book on Peer Instruction For Astronomy (a teacher's guide for introductory undergraduate astronomy). See some popular science articles too.
The Chandra X-ray Observatory where I work in the Director's Office. And a video where I philosophize about the Universe, Chandra and my job!
HOBBIES especially playing bass with The Wicked Pickers . Before that, J.P. Tropicale with Cornell Coley.
The is from Hubble, showing a distant cluster of (mostly red) galaxies acting as a gravitational lens, producing the optical illusion of 4 (blue) images of the same background quasar.
