Science and Science Fiction: Artificial Gravity in 2001

Tuesday, September 9th, 2008

One of the other issues I didn’t mention yesterday that comes up in hard science fiction is figuring out the parameters for artificial gravity.   It’s relatively straightforward. Here’s the amazing scene approaching the orbiting space station: It’s possible to calculate the gravity on board the outer ring. Wikipedia provides the necessary information in its article […]

Ten Issues for Hard Science Fiction

Monday, September 8th, 2008

There are a number of issues that continue to keep coming up in hard science fiction, or any science fiction trying to get the facts right.   I just helped my collaborator here a few days ago answer a reporter’s questions on one of these (humans expelled into space without space suits).   These things should always […]

Ten Things I Hate About Science Fiction

Friday, September 5th, 2008

First off, I love science fiction, but when it’s bad, oh boy, there’s little worse. As a writer and scientist, I’m probably more sensitive to some of the bad things than the average person, but there are plenty of things that happen too often that we can probably agree to share for a good two-minute […]

Science Fiction in Science

Wednesday, September 3rd, 2008

Sometimes I tell people that I write science fiction for Tor and the Astrophysical Journal. That’s tongue in cheek, mostly, but there is a lot of stuff that scientists work on that is, for want of a better term, “science fiction.” Except that it’s very well-informed with science and worked out in some detail. It’s […]

What is a Quasar?

Friday, August 22nd, 2008

When I travel and meet a lot of new people, they often ask what I do. When I tell them that I’m an astronomer, and they don’t immediately mumble something about liking astrology or make some other outrageous statement as sometimes happens, they’ll often follow up and ask what, specifically, is my specialty. “Quasars,” I […]

Rocket Scientists Are Stupid Smart People

Wednesday, August 20th, 2008

OK, maybe, maybe not, but Robert Lemos writing for wired.com, playing up the hyperbole, makes them sound like it with this pronouncement: Rocket Scientists Say We’ll Never Reach the Stars. Which I don’t think anyone quoted in the article ever quite says. Never say never, especially in cases of engineering. It isn’t impossible to reach […]

Unique Astronomical Environments

Saturday, August 9th, 2008

One of the things I like doing as a writer is inventing something new in science fiction. It’s been said that there are no new stories to be told, and while that’s true at some level, every story is unique and there’s always the opportunity to bring something new to the table. I read sf […]

Online Astronomy Resources for Writers

Tuesday, August 5th, 2008

I throw a lot of links at the writers attending the Launch Pad Astronomy Workshop for Writers. I usually do it on the fly before a lecture, or embedded within lecture slides. It made sense to pull them out and to put them in one place with a little organization. The idea is that these […]

Star Colors

Tuesday, July 29th, 2008

Phil Plait at Bad Astronomy addresses the question of why are there no green stars.   It’s a nice post and brings together astronomy and biology in interesting ways, and reminds me of the posts I did a couple of months ago for a friend who’d just sold a story about life on a world orbiting […]

Ten Great Examples of Science Fiction World Building

Monday, July 28th, 2008

I am taking part in a Mind-Meld post over at sfsignal.com later this week. The subject is our favorite example of world-building. The ultimate in world-building was probably Lord of the Rings, for which J.R.R. Tolkien invented entire languages and histories. Not my favorite though by a long shot (did all the ballads and poems […]
