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.

"The mind, once expanded to the dimensions of larger ideas, never returns to its original size." -Oliver Wendell Holmes When General Relativity supplanted Newton's work as our theory of how gravity works in the Universe, it didn't just change how we view how masses attract, it gave us a new…

"When I say, 'I love you,' it's not because I want you or because I can't have you. It has nothing to do with me. I love what you are, what you do, how you try.

"There are some things we do much better than computers, but since most of chess is tactically based they do many things better than humans. And this imbalance remains. I no longer have any issues. It’s a bit like asking an astronomer, does he mind that a telescope does all the work?" -Vishy Anand…

"Get your facts first, then you can distort them as you please." -Mark Twain I am unimpressed with speculations that have no basis in fact, but if you can show how your claims are factually grounded and arrived at, they're certainly worth a listen to.
