Science and Science Fiction: The Moons of Mars in Watchmen

Saturday, March 28th, 2009

In the movie Watchmen, there is a scene that takes place on Mars and two large, round moons are visible in the sky.   Mars does have two moons, Phobos and Deimos, but they are not large, round moons.   Phobos and Deimos  are tiny, with an approximate diameters of 22km and 13km, respectively, and not exactly round. […]

Science and Science Fiction: Humans as Batteries in The Matrix

Wednesday, March 18th, 2009

The Matrix is a pretty cool movie, a modern classic with an interesting premise and innovative special effects.   I always had a problem with it, related to the premise.   Some spoilers may follow.   Here’s my problem scene: I’m not going to question the information about how much electricity or heat a human being can generate.   […]

Movie Scenes with People Exposed to Vacuum

Monday, March 16th, 2009

I’m working on my seminar about science in the movies, and one of the concepts discussed will be what happens when you chuck someone out an airlock without a space suit.     We know what happens.   There was a poor guy who had an accident in a high-altitude chamber in the 1960s and lived to tell […]

Scientists Sometimes Need to Think Like Science Fiction Writers

Saturday, March 14th, 2009

Not every scientist has an interest in science fiction or anything resembling the ability to think like a science fiction writer. I was reminded of this again today in regard to this story about how to focus SETI searches. Basically, the idea is that it is easier in principle to find and characterize Earth-like planets […]

Using Movies to Teach Science

Friday, March 13th, 2009

This is a favorite topic of mine.   I love stories and I love science, and science fiction movies combine these. Unfortunately one or the other usually suffers from the combination.   Still, for the purposes of education, getting the science wrong can be as instructive as getting it right, if not more so. I have been […]

The Science of The Watchmen

Monday, March 9th, 2009

OK, not quite getting away from The Watchmen quite yet.   A friend pointed me at a video about the science of The Watchmen: University of Minnesota physics professor James Kakalios discusses how he was tapped to add a physics perspective to the upcoming Warner Brothers movie, Watchmen. Kakalios discusses how quantum mechanics can explain Dr. […]

Supernova Explodes, Changes the World

Wednesday, February 25th, 2009

Overblown title for something much more subtle, but profound and cool. Scientists have discovered evidence of several supernovas in Antarctic ice cores.   The evidence is a spike in the concentration of nitrogen oxide, an expected effect from a flood of gamma rays hitting our atmosphere.   Two of the three spikes found match known supernovas observed […]

Originality in Science Fiction

Saturday, February 14th, 2009

First, what does it mean to be original?   Well, I guess it means to be first with something. But what does that mean? Well, maybe nothing, really.   Over at Techdirt there’s an article suggesting that nothing is original.   It’s the old idea that nothing is created in a vacuum, and specifically applied to our current […]

AAS Action Alert 2009-01: Call Your Members of Congress and Have Them Support Science in Stimulus Bill

Tuesday, February 10th, 2009

From the American Astronomical Society (AAS).   It is specifically calling astronomers to action, but anyone, in the sciences or not, should be encouraged now to call their members of Congress and ask the to support science in the stimulus bill.   It’s a little trickier for me bring in Brazil at the moment, but modern internet […]

Fossilized Science in Science Fiction

Sunday, February 8th, 2009

Leaping off from a thread started by James Nicoll on his LJ blog where he blames Larry Niven for entrenching the idea in science fiction that a supernova close to another star can cause the second star to also go supernova, based on his 1966 story “At the Core” which underlies his entire Known Space […]

How to Win at Science

Friday, February 6th, 2009

Warning: this post is practical advice for the individual and risks breeding cynicism toward science. I am a tenured professor of astronomy at the University of Wyoming, a category I research university where I enjoy a relatively low teaching load and decent pay, and where I lead a research group that has brought in close […]

How to Talk with the Mundanes

Monday, February 2nd, 2009

So, over in science blogger/skeptic land, there’s been a discussion about how to talk to the believers.   This comes up for well-educated, rational people all the time.   Most of my friends have advanced degrees, talk about things they know well, and don’t have totally wacky beliefs.   The ones that do have wacky beliefs wear them […]
