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.

“Never waste your time trying to explain who you are to people who are committed to misunderstanding you.” -Dream Hampton As any scientist knows, it's true that no scientific theory, no matter how well-tested, how validated, or how universally applicable it is, can ever be 100% proven. Image…

“People are trapped in history and history is trapped in them.” -James A. Baldwin We've come a long way since we first started watching the night skies. Even just a century ago, we thought our Universe was governed by Newtonian gravity and consisted only of our Milky Way and the stars inside.…

“The whole difference between construction and creation is exactly this: that a thing constructed can only be loved after it is constructed; but a thing created is loved before it exists.” -Charles Dickens Just... go. I can't even do it justice in a synopsis, or with 600 pixel image widths. This…

“A physicist is just an atom’s way of looking at itself.” -Niels Bohr There's a wonderful story that the Universe tells us about itself: the story of where everything in it came from, and how it came to be this way. From the perspective of a human being, there's possibly no component of that as…

“What is that feeling when you’re driving away from people and they recede on the plain till you see their specks dispersing? — it’s the too-huge world vaulting us, and it’s good-bye. But we lean forward to the next crazy venture beneath the skies.” -Jack Kerouac But how do you say goodbye to a…

“The larger the island of knowledge, the longer the shoreline of wonder.” -Ralph W. Sockman After millennia looking up at the Milky Way overhead, it's only recently that we discovered our galaxy had a spiral-like structure, and that the other spirals and ellipticals in the night sky are galaxies…

“Be miserable. Or motivate yourself. Whatever has to be done, it’s always your choice.” -Wayne Dyer We all can think back to that moment that happened where we knew our lives would be forever different, right? To that one moment in our past where we suddenly knew what it was that we wanted to be,…

“It is always the simple that produces the marvelous.” -Amelia Barr All things being equal, the simplest explanation is usually the best. At least, that's how Occam's razor is most commonly phrased these days. Yet, when it comes to the headlines -- whether it's a "discovery" of dark matter or "…

We don't normally think about it in our day-to-day work, but as scientists, our equations, our models, our observations, our experiments and our instruments are more than just our tools for approaching our work. In a very real way, they're our connection to the Universe itself. Image source: http…

They say that a cat has nine lives, mostly because of their uncanny ability to find themselves in -- and escape from -- frequently perilous situations. Perhaps, of all the animals that he could have chosen, that's why Schrödinger made his famous thought experiment about the most diminutive of…

We all have our own interpretation of what "the scientific method" is, but there's always at least one thing that they all have in common: the ultimate arbiter of whether a theory or idea is valid depends on the evidence that comes back from physically observable phenomena. Image credit: abstruse…

“To begin, begin.” -William Wordsworth Is the Big Bang the greatest scientific achievement of the 20th century? I -- along with many others -- would argue that it is. It's something that even young children are curious about! Image credit: David Burstein, of http://www.davidburstein.net/2012/10/07…
