Why I Don’t Worry, Part 2
Last time I explained why I don't lie awake nights worrying that contact with extraterrestrial civilizations will lead to humanity getting conquered by invading alien armies. It's just too hard to be worth the effort. But what if the aliens don't want to conquer the Earth? What if they just want to wipe us out?…

Why I Don’t Worry, Part 1
Last month, this New York Times article by Steven Johnson raised the alarming question: what if our efforts to find and communicate with other intelligent life in the Universe brings us to the attention of intellects vast and cool and unsympathetic who want to wipe us out? The author quoted Stephen Hawking, warning that the…

Ozblogging: Tik-Tok of Oz, Part 4
And now we meet the great arch-villain of the Oz books once again: Ruggedo the Nome King — alias Roquat, as he was originally known. I don't know why L. Frank Baum changed the Nome King's name; the in-story explanation is that Roquat forgo his original name upon drinking the memory-erasing Water of Oblivion in…

Future Creep
I recently spent an informative day sitting around a big table discussing medical robotics with a bunch of people who knew a lot more about medical robotics than I did. Since we were talking about modern cutting-edge technology or next-ten-years developments, the technical experts were all very clear that the "robots" in question will be…

The Argument For Space
I've always been a fan of space exploration, which means I've often gotten into arguments with people over the value of doing it. NASA (among others) spends a lot of its public-relations budget promoting the importance of exploring space, but I think they focus on the wrong things. On the NASA web page there's a…

Inoculating Against Woo
A while back I posted a little joke about why Marty McFly's father George, in the movie Back to the Future, is the worst science fiction writer ever. One of my complaints was that George couldn't bring himself to publish his stories until a midnight encounter with a fake "spaceman" convinced him it was all…

Movie Magic
Last weekend the family went out to see Dr. Strange, the latest Marvel Comics movie. This one is the origin story for Dr. Stephen Strange, Sorcerer Supreme and master of the mystic arts. It was entertaining and visually wonderful. It did get me thinking (uh-oh) about how magic is depicted in most modern films — and…

Biology of the Body Snatchers
(Note to everyone who is still sitting on the edge of their seat waiting for the promised follow-up to my last post: be patient. It's Halloween today so I'm doing a Halloween post.) This past weekend I took my son to see the original Invasion of the Body Snatchers (1956) at Amherst Cinema. It was extremely…

Science to the Rescue!
In the past I have mentioned my love of doing research and my focus on getting things right in my writing. Along the way I've pointed out how frustrated I get when moviemakers don't bother trying for accuracy. Well, it turns out I'm not alone. The mighty National Academy of Sciences apparently also makes angry…

The Fermi Paradox and Why It Matters
As a science fiction writer I have what may be called a professional interest in aliens. I read every popular science article or technical paper that comes to my attention about detecting or communicating with extraterrestrial civilizations. But I'm always a little surprised at how many people aren't interested in the subject. To me it…
