The Red Light District Part 2: The Light Bulb Paradox

Monday, June 9th, 2008

I had a post over the weekend where I claimed that life on a planet around a type M star (see classifications here) would be like living in a red light district. Not the sex part, just the red light part. M stars are cool as stars go, around 3000 Kelvin or a bit less, […]

The Importance of Science in our Lives

Friday, June 6th, 2008

Brian Green has an op-ed in the New York Times speaking about the personal importance of science in our lives.   It is a good article, and meaningful, in my opinion.   Science has enabled you to read this post, but it has also done so much more.   Reflect on that. Sometimes I feel like I’m a […]

Press Conference Experience

Tuesday, June 3rd, 2008

I overslept and almost missed it yesterday!   The traveling, stress, and lack of sufficient sleep caught up to me.   I made it over okay, with a couple of minutes to spare.   I wanted to make some adjustments to the slides and practice the talk again just before the actual event, but didn’t have time. 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 […]

What do (Astronomy) Professors Do?

Sunday, March 23rd, 2008

As a professional astronomer with a faculty job as a professor at the University of Wyoming, I find it very common that people outside of academia don’t really understand what it is I “do.”   A lot of misconceptions floating around there, so let me knock some down first before building something in their place. First […]

The Science of Spider Star

Friday, March 7th, 2008

“A dark-matter world holds the key to a weapon from the heart of a sun.” That’s the tagline on the cover.   My new hard science fiction novel, Spider Star, was published by Tor this week. I’m pretty happy to finally have the book out, the current expression of my attempts to make my career in […]

Earth’s Final Sunset

Wednesday, February 27th, 2008

The Earth is toast. New and improved calculations make a strong case that when the sun expands into a red giant several billion years from now our planet will spiral into the sun’s photosphere and disintegrate. The space.com article also suggests that there is a way to save the Earth, at least for a while. […]

Science and English

Tuesday, February 19th, 2008

Recently a friend of mine pointed me at this story. The issue of contention is that English has become the de facto language of science. In most fields, almost every paper is published in English, and all conferences use English. This didn’t use to be the case (and most graduate programs in the sciences had […]

Ten Superpowers You Can Have Now

Wednesday, February 13th, 2008

I was thinking today about the “Reals” of the Heroes Network and what superpowers are now within the reach of our science and technology. Most superpowers are ridiculously unphysical, as described in the really fun book, Physics of Superheroes, which the author James Kakalios fashioned after a class he teaches at the University of Minnesota. […]

Is Space Exploration Worth the Cost?

Monday, January 14th, 2008

A few days ago there was a New York Times Freakonomics blog entry on this question that’s worth a read.   I suspect anyone finding their way here is going to agree with the people interviewed there, and with me, that the answer is “yes.”   In particular there, the question referred to “manned” space exploration, which […]

Top Ten Science-Based Science Fiction Movies (Revised)

Sunday, January 13th, 2008

  I posted this originally at www.sfnovelists.com, but decided that I’d like it in my own archives, too, and it would make a good filler for a lazy Sunday (which isn’t really because I have to write a self-assessment and run for three hours today, but that’s my problem).   Anyway, here it is in case you […]

Science in my Science Fiction: Books vs. Movies

Wednesday, January 9th, 2008

So yesterday I had a post about what I thought were the ten best science fiction movies in terms of the physical science.   I’ve been convinced to make a couple of substitutions and will do that over at www.sfnovelists.com tomorrow with a link from here.   One reaction I often get when I become critical about […]
