I’ve discussed some world building before, and this has traditionally been an important topic in science fiction and fantasy. I want to get a little more specific where it comes to space-based interstellar science fiction. These days I think it’s becoming necessary to be very specific in any human-based, Earth-oriented future to use real astronomy […]

Here’s the letter below asking for input (until March 19th). I am particularly thrilled about NASA’s questions and especially the only about video game development (question six). This is a potentially very powerful way of getting at the younger generation before college level. I wish I’d seen this sooner and had more time to participate. […]

In physics, the two-body problem, two objects moving under mutual gravitational attraction, is solved analytically and completely. No uncertainties. Simple. Undergraduates in upper-level mechanics do it all the time. In pursuing a career in academia, and going on my experiences in astronomy, the two-body problem that is much more challenging is having a relationship or […]

There’s an article about artificial limbs with a picture of an attractive woman, a double-amputee, running along the beach. The premise of the article is that some artificial limbs are starting to outperform original limbs, in at least some ways. This trend will continue into the future, no doubt, until we have the capability to […]

I missed our astronomy journal club today, so I thought I could take some of that time I “saved” and invest it here in talking about what is journal club. In the sciences, you generally finish classes in your second year of graduate school, and are not likely to take more. Teach more yes, but […]

I was just thinking of, or trying to think of, video games with good science that teach a little science. As usual, I tend to think of physics and astronomy, and the things that occur to me first are usually down this line of thinking. I know that I’ve missed a lot of PC games […]

All of writing hinges on knowing your audience. This is true of fiction and non fiction, and applies not only to writing, but communication of all kinds from entertainment to education. I’ve been thinking about this a lot after reading Randy Olson’s very interesting and worthwhile book Don’t Be Such a Scientist, which is about […]

Now, I don’t expect everyone to love everything that I love, but I do know that everyone loves the results of science even if they don’t readily acknowledge it. I mean, people love using the internet, driving cars, being warm in the winter, getting medicine when they are sick, all that good stuff. But even […]

I am such a nerd. There is no reasonable answer to my question, except for the obvious “he’s an alien, that’s why” or “shut up and stop being such a nerd!” (Why Superman should look like a human at all is another question I won’t ask for now, as is why doesn’t anyone see through […]

New Scientist has an interesting article about novel methods for interstellar travel, which includes links to recent scientific articles: In August, physicist Jia Liu at New York University outlined his design for a spacecraft powered by dark matter (arxiv.org/abs/0908.1429v1). Soon afterward, mathematicians Louis Crane and Shawn Westmoreland at Kansas State University in Manhattan proposed plans […]

My friend and fellow astronomer/science fiction writer Valentin Ivanov pointed me at these abstracts saying they reminded him of Star Dragon (which has creatures living in an accretion disk): Title: Accretion disk civilization 1: Habitable zone around accretion disks at galactic nuclei. Authors: Fukue, J. Publication: Astron. Her., Vol. 88, No. 5, p. 199 – 205 […]

This is just going to be a short post tonight on a topic I have discussed before and will likely continue to discuss. Politics in the United States has become so polarized that few politicians cross party lines. It is one team vs. the other, rather than real issues with real solutions that are not […]
