Science vs. Fantasy: A False Dichotomy

Wednesday, April 30th, 2008

There have been a number of books/movies/tv shows presenting conflicts between rationial vs. scientific world views on the science vs. fantasy spectrum. I submit that they’ve all been unfair. I recall watching Northern Exposure on TV some 15 years ago, more or less. It was an interesting show about a doctor with a fellowship compelled […]

What Would It Look Like from Inside a Nebula?

Monday, April 28th, 2008

One of the questions I’ve gotten as an astronomer with science fiction sensibilities more than a few times is about how nebulas would appear if we were in one. Phil Plait, the “Bad Astronomer,” has considered this issue and made a video about how to think about the issue: So, nebulas look cool through a […]

Booklist Starred Review for Spider Star

Sunday, April 27th, 2008

  My first novel, Star Dragon, got a starred review from Booklist, which a lot of librarians use in purchasing decisions.   I hadn’t seen their review for Spider Star until now.   It’s also a very positive starred review: The author of Star Dragon (2003) returns with another compelling work of hard sf, this time involving a […]

The Difference Between Spiral Structure in Galaxies and in Hurricanes

Saturday, April 26th, 2008

I was giving an astronomy talk at a Worldcon a few years back and was showing some pictures of some spiral galaxies like this Hubble image of M81: Someone in the audience asked if the spiral shape of hurricanes and galaxies were for the same reason.   Here’s a picture of Hurricane Floyd from NASA (who […]

The Disappointing Veneer of Science in Science Fiction

Friday, April 25th, 2008

I like stories of all types, not just hard science fiction. I can get excited about a good fantasy, or a good story of any kind. What I can’t stand, however, is the pretending. Crap pretending to be science, making it harder to find the real thing, and making it harder for the public to […]

Science and Science Fiction: Nanotechnology

Thursday, April 24th, 2008

That’s the topic for my class this week, and I just wanted to share a brief introduction with some links to some interesting videos and history regarding nanotech. Let’s start with NASA Kid’s introduction to nanotechnology. Then there’s a nice, more adult introduction with a summary of current nano state of the art. Historically, the […]

What Science Isn’t

Thursday, April 17th, 2008

I generally only censor spam or super obnoxious posts from my blog, and luckily haven’t had any in the second category (knock on plastic). I’m in turns bemused and annoyed with comments on some entries, like this one, about the antiscience propoganda piece that is Expelled. I know I’m going to be preaching to the […]

Awesomely Bad Quasar Article: Science Journalism, I Cry for Thee!

Wednesday, April 9th, 2008

Grrrr!!! No one better tell me about how science reporting is good and I’m being unfair. I dare you. I double dog dare you. My research specialty is quasars. I love quasars. I’m a world expert, and I know more than anyone you know about them, and also what we don’t yet know about them. […]

Science and Science Fiction: What Exactly Is Teleportation?

Monday, April 7th, 2008

A comment on my Standing on the Ledge with Jumper post got me thinking about this issue today. I realized that to a great degree my disagreement with others concerns the definition of teleportation, and how I think that the standard has slipped for PR purposes. I think at one extreme every can agree on […]
