Ethan Siegel

Ethan was born in New York City as the son of a Jewish postal worker. He did his undergrad at Northwestern, taught public school in Houston, Texas and Los Angeles, California, before moving to Florida, where he got his PhD in theoretical astrophysics at the University of Florida. After that, he moved to Madison, Wisconsin, where he taught at the University of Wisconsin, ate too much cheese, and also met his life partner, Jamie. After working in astrophysics research at the University of Arizona and starting the world-renowned science blog, Starts With A Bang, he moved from the hellish desert to rain-soaked Portland in 2008. Since then, he's been a professor at the University of Portland and Lewis & Clark College, grown a nationally renowned beard and mustache, got invited to join a circus and probably drank more beer than a healthy person should. He currently works as the head curator at Trapit, and can't wait to tell you a little bit more about the Universe.

"Illusion is the first of all pleasures." -Oscar Wilde It's tough to tell fact from fiction, and sometimes just as hard to tell reality from illusion. As long as you're enjoying yourself this weekend, I'd have to agree with Buckwheat Zydeco, and say Let The Good Times Roll. But despite what these…

"One of my favorite philosophical tenets is that people will agree with you only if they already agree with you. You do not change people's minds." -Frank Zappa One of the most difficult things to talk about, for any self-respecting scientist, is politics. Like all of you, I have my preferences, my…

"A man's face is his autobiography. A woman's face is her work of fiction." -Oscar Wilde It's an intense world out there, and life can leave you weary in many ways. And sometimes, making your way through each day makes it feel like the whole world is watching, and there's no hiding. Have a listen,…

"From my close observation of writers... they fall into two groups: one, those who bleed copiously and visibly at any bad review, and two, those who bleed copiously and secretly at any bad review." -Isaac Asimov You'd never know it unless you were one of about six people in the entire world, but…

"...because today, with cameras as pervasive as they are, there is no such thing really as professional photographers." -Marissa Meyer Before you get irate, I don't actually agree at all with that quote above; I have no talent for photography at all and a tremendous respect for those who do, and…
