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 […]

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 […]

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 […]

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 […]

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 […]

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 […]

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 […]

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 […]

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 […]

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. […]

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 […]

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 […]
