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 […]

Poll: Best SF/Fantasy/Horror Movie Soundtrack?

Sunday, February 22nd, 2009

OK, I don’t want to repeat myself exactly from yesterday’s sf band thing, but I was inspired by Phil Plait’s post about this utterly fantastic video: As you may or may not know, Orff’s ‘O Fortuna’ was used extensively in the movie Excalibur.   Other parts of the soundtrack had this great theremin-sounding stuff and wailing […]

A Poll: Your Favorite Science Fiction Band?

Saturday, February 21st, 2009

Last week I linked to an article about how U2 was the greatest science ficiton band.   I like U2, but think that the claim is ridiculous.   Am I alone?   I suggested some bands like Queen, Iron Maiden, the Orbital, and Blue Oyster Cult were much better choices.   U2 just doesn’t do that much stuff I […]

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 […]

Home Schooling the Science Fiction Way

Saturday, February 7th, 2009

I wrote a short post about homeschooling last year that criticized one specific opinion held by one particular homeschooler, and while it was a good criticism, it got in the way of the positive potential homeschooling has.   I said then, and I will say again, that I have no love for homeschooling done for wrong […]

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 […]

The Long and Short of It: Statistical Arguments

Sunday, February 1st, 2009

So there’s an inflammatory post on the physics preprint server blog with the headline Massive Miscalculation Makes LHC Safety Assurances Invalid.   It’s based on a paper by Toby Ord and others titled “Probing the Improbable: Methodological Challenges for Risks with Low Probabilities and High Stakes.”   Here is the abstract: Some risks have extremely high stakes. […]

Interview with Eric Nylund, Author of Mortal Coils

Tuesday, January 27th, 2009

In addition to being a great writer, Eric Nylund is an old friend of mine.   I first met him and became a fan of his at the Clarion West Writing Workshop back in the 1990s.   Eric has written original science fiction and fantasy for well over a decade now, and more recently has hit the […]

The End of Books?

Friday, January 23rd, 2009

I’m not exactly talking about ebooks or transitions of technology.   I’m talking about Larry McMurtry’s contention that we may be living in the twilight of the novel.   (Note that he happens to be giving his talk on this topic, ironically perhaps, at Rice University where I literally read hundreds of novels as an undergraduate in […]
