In my free time I enjoy cooking, sports (rock climbing, tennis, badminton, and cycling), reading, and photography.
Stuff Matters: Exploring the Marvelous Materials that Shape our Man-made World
The Righteous Mind: Why Good People are Divided by Politics and Religion
Before the Dawn: Recovering the Lost History of our Ancestors
Beyond Religion: Ethics for the Whole World
... apparently I like reading books that have a colon in the title.
Movies: Interstellar (I am an astronomer after all...).
Shows: College basketball (does that count as a show? if it doesn't, it should), The Big Bang Theory, and Modern Family.
Music: alternative rock -- The Goo Goo Dolls, Coldplay, Vertical Horizon, Snow Patrol, etc. Periodically I like to pretend I'm cultured and go to Columbus Symphony or ProMusica concerts.
FOOD! My sister turned me into a foodie of sorts. I love to try new recipes, but some favorites include: chicken parmesan, saute'ed scallops, and clam chowder.
