Three Thoughts for Halloween

posted in: quirky, science, technology 0

No, not spooky thoughts, or even deep thoughts. Just…weird, funny, unexpected.

I’m sure you all know what CAPTCHAs are. No? I didn’t, either, until I read the article I’m about to refer you to. But you’ve dealt with them. CAPTCHAs are those little boxes where you have to decipher squiggly or morphed letters of the alphabet and type them into another box before you can proceed (for example, to add a comment to this blog). Their purpose is to ensure that a real human, and not a robot, is leaving a post or opening an email account.

The evil spammers have come up with a new way around these: a sexy picture of a scantily clad blonde, and an invitation to entice her to take off her clothes by…yes, deciphering a CAPTCHA and entering the code. But when you do this, you’re performing a service for the spammers: enabling them to get past these protective devices. Read about it on the Washington Post Security Fix column, where I saw it.

To veer wildly in the direction of the physics of life, ponder the possibility that life may evolve in the form of plasma or ionized dust creatures (in space). Invasion of the Plasmozoids! Or whatever you might like to call them. The New Scientist magazine has asked for ideas of what to call these hypothetical beings.

And for one final twist into oddity, watch this brief video of a train in Bangkok. Be sure to watch all the way to the end.

Happy Halloween!

Sputnik, Half a Century Later

Can it really be fifty years since Sputnik beep-beeped its way around the globe, ushering in the space age and scaring Americans half to death? (The Commies are going to bomb us! Their rockets work, but ours always blow up!) I guess it has been. (By the time I get this up, it’s going to be October 5, but let’s just pretend it’s still October 4, okay? I mean, somewhere in the U.S., it still is.)

Lots has been written in newspapers and elsewhere about the anniversary, but I thought I’d note a few reflections about what Sputnik meant to me, an 8-year-old kid in Huron, Ohio. I remember fear, because the Russkies were ahead of us. But I also remember great excitement, because we were finally in space! (In this part of the brain, it was okay to think of them as being part of us, which was really how I preferred to think of things anyway.) In the long run, the excitement way outweighed the fear. The Space Race was on!

I can still taste the thrill of watching our early rockets lift off, of following every single space mission with intense interest—and I don’t just mean manned space missions. I mean everything. The Echo satellite, a big Mylar balloon that reflected radio waves. Telstar, the first active communications satellite. Ranger and Surveyor to the moon. Mariner to Mars and Venus. I knew all the rockets by shape and size: Delta, Atlas, Titan, Atlas Agena, Atlas Centaur, Saturn. I knew what rockets were coming down the pike. (I’m still waiting for the Nova, which would have dwarfed the Saturn V.) I idolized Werner von Braun. (We didn’t know about the Nazi part then.)

And then, of course, there were the manned missions. I remember our classes at school (6th or 7th grade) being pulled out to go to the room where there was a TV to watch both the scrubbed attempts and finally the launch of Alan Shepherd into space. “Why don’t you fix your little problem and light this candle?” I think I was at home for Gus Grissom’s flight. In school for John Glenn’s. It was a wondrous time. So full of passion and innocence. But I also remember the devastating news of the Apollo 1 fire, which put an end to the innocence. And finally on up to the landing of the Eagle. “Tranquility Base here…” I still get shivers when I watch video footage of Apollo 11’s launch.

Besides engrossing me, one pronounced effect of this ferment of space activity was my passion for reading science fiction. I’m pretty sure the two were linked. As I watched the real space travelers, I had no doubt—one iota of doubt— that our future as a species was in space. I lived that future through the exploits of Tom Swift, Jr. and Tom Corbett, Space Cadet—and of course through the stories of Heinlein and Asimov and Clarke and Leinster and Del Rey and Lesser and Nourse and Norton and White and a hundred others. I never felt that there was anything unreal about these visions of our future in the stars. On those periodic occasions when someone asked me why I didn’t read about real things, I simply didn’t know how to answer; the question made no sense to me.

In a way, it still makes no sense to me. That was the beginning but not the end of my love affair with science fiction, and I have always felt that it was the most real of all kinds of fiction.

Hey, Sputnik—thanks for getting the ball rolling.

Dark Matter Galaxies, and the Loss of a Literary Star

Space.com reports the apparent discovery of “Hobbit” galaxies—tiny, ultrafaint, dwarf galaxies in our local group—which appear to consist mostly of dark matter. Though they were observed by their stars, which presumably are made of normal matter, gravitational calculations based on the movements of the stars indicate that the galaxies are 100 times more massive than the estimated total mass of their stars. The rest? Dark matter, more than likely. The findings will be published in the Astrophysical Journal in November.

Meanwhile, you may already have heard that Madeleine L’Engle died on September 6, 2007, another great loss to the book world. She is best known, of course, for the A Wrinkle in Time series of young adult novels, but she wrote many other books, as well. (Her official web site)

I never got to meet her, though we exchanged some correspondence once. Paradoxically, I didn’t discover her books at a young age, but as an adult. (Someone tried to turn me on to A Wrinkle in Time at a particularly sensitive age—when I didn’t want to read “YA” and I didn’t want my SF to read like fantasy. So that effort failed. But I tried the book years later, and that time it clicked. Marvelous.)

Farewell, creator of Mrs. Who and all the others. And thank you.

“You have to write whichever book it is that wants to be written. And then, if it’s going to be too difficult for grown-ups, you write it for children.” —Madeleine L’Engle

Strange and Exotic Robots on TED

posted in: quirky, science 0

Dutch artist Theo Jansen has created an extraordinarily odd set of moving sculptures, which any normal person would want to call robots, though they have no intelligence and are purely mechanical creations. He speaks of them as being “Strandbeests,” and when you watch, you will understand why. Take a look; it’s about an eight-minute video. I’ll wait.

You can also view it in a separate browser window and read some background info on it. While you’ve got that open, check out some of the other videos listed in the TED sidebar. (TED stands for Technology, Entertainment, Design. That’s the name of the web site that presents these pieces.) They’re all of a scientific and/or artistic bent.

Lunar Eclipse and New Writing

I wasn’t able to see the August 28 lunar eclipse, but Jerry Oltion—SF writer, amateur astronomer, and member of our Launchpad astronomy team—sent us a photo he took. I thought it was so beautiful, I asked his permission to put it here on my blog:

Photo by Jerry Oltion

Seeing the photo reminded me of one of the NASA pages I read prior to the eclipse, suggesting that we imagine what it would be like to stand on the moon during an eclipse, surrounded by that incredible copper-glowing landscape. I think it would be a pretty mind-blowing experience. And as Jerry said, “Imagine what the Earth would look like from there. A dark hole in the sky with city lights glowing in it, surrounded by a ring of blood-red atmosphere.”

Here’s a montage Jerry put together, of the phases of the eclipse:


Jerry has larger images on his website, and they’re worth a look; these smaller reproductions don’t do them justice.

Meanwhile, I’ve been putting finishing touches on a short story (my first in many years!) that I hope will find its way into print eventually. More on that when I have something to report. (The name of it is “Dog Star.”)

Starting a new book is often just about the hardest thing in the world for me, and I’ve been having a devil of a time getting anywhere with the beginning of the next Chaos book, to follow Sunborn. Tonight, I decided to take Buckbeak out for a spin after dinner, in hopes that the night air would clear my head and bring some inspiration. It worked, at least a little bit. I came home with a couple of new thoughts on how to make this beginning work, and I’ve started putting it down in pixels and electrons. Feeling more hopeful, and now let me get back to it!

A Star That Sheds Like Our Cat!

posted in: quirky, science, space 0

By now, you’ve probably seen news reports about the star Mira (pronounced my-rah), in the constellation Cetus. It’s barreling through the galactic medium at unusual speed and as a result is shedding a trail of starstuff. In the ultraviolet pictures from NASA’s Galaxy Evolution Explorer, it looks like a comet:

The Star
Our cat

You might not have seen the cool animation NASA has online, though, along with explanation of how it is probably a bow-wave effect that’s causing the tail.

There’s supplemental material on another NASA page.

I can’t believe how much great astronomy has been coming our way in the last year or two.

Catching Up with Interesting Science/Tech Stories

posted in: science, technology 0

While I was finishing work on Sunborn, I saved up a bunch of links to interesting new developments in science and whatnot. Time to send some your way before I lose them.

  • Astronomers have discovered dark caves, or holes in Mars! They might be a place where life could be lurking, sheltered from the sun.
  • In one of the more breathtaking views I’ve seen lately, Saturn was caught emerging from behind the Moon. It looks like a close neighbor, but really it’s over a billion kilometers away.
  • In a series of amazing images of another kind, artist Chris Jordan shows us profound views of what our consumption of products, as a society, really looks like. It’s called Running the Numbers.
  • Finally, from New Scientist, a couple more news items caught my attention: a new theoretical approach to teleportation (no, I can’t say I understand it, but…), and a new dino discovery, Gigantoraptor, a feathered dino big enough to face off with a T-Rex.

More Cool Science

New Scientist has a bunch of interesting mini-articles in today’s newsletter. And if you follow these links, you’ll see a lot of other interesting articles listed in the sidebars. Take a few minutes to browse; there’s some cool stuff.

Here’s a sampling:

Here’s one that’s more sobering than cool, but it deserves reading: Taking stock of Earth’s dwindling mineral wealth. (This one you can only read a partial of unless you’re a subscriber, but the partial is pretty interesting in itself.)

Extragalactic Dark Matter Ring

posted in: science, space, writing 0

Okay, just one more entry before I head off! This image of a 2.6-million light-year-wide ring of dark matter, surrounding a cluster of galaxies, is too incredible to pass up.


To see a gorgeous, full-sized image of it, look to Astronomy Picture of the Day.

For further explanation, read the news report at space.com. One thing they don’t say there that they do say on the APOD page is that the large blue ring is a digital modeling that has been superimposed over the Hubble image. I’m a little puzzled at the discrepancy there, and am not sure at this point whether the blue cloud is entirely a false-color representation or not. It must be, though, because the thing about dark matter is that it’s, well, dark. You can’t see it. (Except in a scene late in my novel Sunborn, but that’s another matter.)

To get a better grasp of the science behind the conclusion, check out this short Hubblecast video, which describes the gravitational lensing effect that actually supports the thesis that this really is dark matter being depicted and not just some camera artifact.

————-

In a complete change of subject, I’ll just note the passing of Jerry Falwell, who probably did more to promote the cause of bigotry and intolerance in our society than just about anyone claiming (in a chillingly distorted way) the banner of Christianity. I don’t wish him ill; but I do hope he’s seeing things a little differently now.

“To send light into the darkness of men’s hearts—such is the duty of the artist.”

Shields Up?

One of the thorniest questions relating to interplanetary travel, or even long-term residence on the moon, is danger to astronauts from radiation. I’ve often wondered why magnetic fields could not be used to protect astronauts in the same way that Earth’s magnetic field protects us. Well, maybe the answer is—they can. A group of British scientists is working on a plan to create a magnetic field 20-30 km around a spacecraft or moonbase, and then fill that space with ionized gas (plasma). The plasma would slow incoming particles and reduce the hazard.

We’re getting awfully close to Star Trek technology here.
