How Do I Get There (Another Star?) — Let Me Count the Ways

Wednesday, April 17th, 2013

I am inspired today by Starship Century, a symposium at UCSD May 21-22, involving Gregory Benford, David Brin, Geoffrey Landis, Joe Haldeman, Neal Stephenson, Alan Steele, etc., almost everyone you might think of from the science fiction side, and a lot of folks involved from the science side (Freeman Dyson, Robert Zubrin, John Cramer, etc.).  […]

Educational Videos for Science Fiction Writers and Critical Fans

Tuesday, April 2nd, 2013

What’s wrong with giant bugs?  Or human bodies exploding in the vacuum of space?  Or the answers to any of a bunch of other questions science fiction writers need to know to craft their story? I’ve written blog posts about some of these in the past, but started noticing videos with similar explanations and thought […]

Science and Fiction from Springer

Friday, March 22nd, 2013

I’m on the editorial board, and an acquiring editor for, a new series by the European academic publisher Springer. I’m busy but agreed to participate because I love the intersection of science and fiction and am the target audience for these type of books, and I bet many of you are, too I have some […]

Friday, February 22nd, 2013

This is a repeat of a post that just went up earlier today at Amazing Stories.  I encourage you to check out the link and join the conversation over there.  Feel free to comment here, too, of course!  Onward… Recently I wrote about eight science fiction tropes of convenience, mainly about unlikely or impossible technology […]

Eight Science Fiction Tropes of Convenience

Tuesday, February 19th, 2013

There are a number of tropes that I see popping up over and over in science fiction, even though they are not very scientifically plausible and border on the impossible given our current understanding.  They are used and will continue to be used, especially in movies and tv, because they’re very convenient.  I find it […]

Science Fiction in the Age of Exoplanet Discovery

Wednesday, October 17th, 2012

From discovering the new planet in the Alpha Centauri system, to the “diamond planet,” to “Tatooine,” this is an exiting time in astronomy.  We’re finding planets orbiting stars beyond our own solar system in ever increasing numbers and with ever increasing diversity.  When I started graduate school to get my PhD, we didn’t know of […]

What If Science Fiction Actually Involved Science?

Thursday, September 20th, 2012

The reason we’ve probably never seen a dramatic TV series involving scientists in the tradition of ER or CSI or Newsroom is that the actual work is usual tedious, boring to most non-experts, with low stakes most of the time (cancer doesn’t get cured every week, or even nearly cured).  This is also the reason […]

What are the Best Science Fiction Mysteries?

Friday, September 14th, 2012

I’ve read and watched some good ones, but I’m sure I don’t know this interesting subfield as well as I should to be able to come up with a comprehensive list.  Let me list some that I think are good to great, and solicit input from others about some that I may have missed.  I’ve […]

10 More Classic Mistakes in Science Fiction Movies

Monday, August 13th, 2012

I came across a kindred spirit today, finding an article titled 10 Classic Mistakes in Sci-Fi Movies. His list takes some well deserved but easy potshots at some large targets, and perhaps more tv shows than movies. 1. Aliens Speak English, often without evidence of translators or any previous interaction with modern English-speaking humans.  Let’s […]

Matt Ridley is a Biased Hypocrite

Wednesday, August 8th, 2012

In the past I would have called him a “stupid smart person,” but I’m moving away from that term, I think, as it’s too prejudicial, in favor of being more specific. Ridley is primarily a writer doing various sorts of science journalism, and definitely a smart guy, but also something of a provocateur.  Controversy brings […]

What Happens When a True Climate Skeptic Does the Science Himself

Tuesday, July 31st, 2012

Richard Muller should have known better, but he’s a physicist, and I know enough physicists to know that some don’t respect other disciplines as much as they should.  This is old news, but with a recent NYT op-ed, he’s laying it out much more clearly than last year: Visit NBCNews.com for breaking news, world news, […]
