Is It Live Or Is It Photoshop?

The following picture has been emailed to me twice now. Maybe some of you have seen it, too. The caption that came with the photo said, in part: “This is the sunset at the North Pole with the moon at its closest point.”

It’s a lovely picture, isn’t it? Don’t you envy the people who were up in the Arctic and saw this? Or wait—did they? Hmmm. What do you think? Is it real or not? Why?

Think about it. I’ll wait. And don’t do a web search on it—that’s cheating. See if you can figure it out from the internal evidence.

Tum-de-tum-te-dum-dum….

I think it’s staring you in the face.

What do you think?

(Don’t make it too complicated.)

I’ll be down below here where you’re ready to talk about it.

Hoom hom.

Okay, that’s long enough. Answer: It can’t be real. The moon is the same angular size as the sun when viewed from Earth–which is why we get beautiful solar eclipses when the moon moves in front of the sun. Its apparent size in the sky varies only slightly due to the eccentricity of its orbit around Earth.

Images are very powerful, aren’t they? And we’re all conditioned to believe that if they look real, they are.

Changing world.

P.S. Only after writing this did I do a search on the image and found that it has some interesting history. It’s a work of art called “Hideaway” by Inga Nielsen. You can read a bit about it at hoax-slayer.com, and see some of her other beautiful artwork. This one was even featured on June 20 on Astronomy Picture of the Day, which I look at regularly; but I guess I missed it that day.

Meme Therapy

posted in: science fiction 0

Meme Therapy is the name of a science-fiction related blog that’s pretty interesting. They’ve wangled a fair number of mini-interviews of authors, and everyone knows authors have interesting things to say. (cough cough) And—oh!—I forgot to mention!—they have a mini-interview with yours truly today. So, instead of writing a real entry here (that would require work, after all), I’m going to send you over there instead.

Is Our Electoral System in Danger?

posted in: public affairs 0

Much has been written about the 2004 presidential election, and questions have abounded about whether or not the election was stolen. The issue is far from settled, though not so much talked about now. But what reawakened my interest was a recent article posted online by Rolling Stone Magazine: “Was the 2004 Election Stolen?” by Robert F. Kennedy, Jr. It’s a long article, and heavily annotated, but it’s well worth reading. If even a fraction of the allegations about voter fraud in the state of Ohio (the state I grew up in) are true, then the implications are staggering.

I won’t try to summarize the many points, but here are a few quotes:

The reports were especially disturbing in Ohio, the critical battleground state that clinched Bush’s victory in the electoral college. Officials there purged tens of thousands of eligible voters from the rolls, neglected to process registration cards generated by Democratic voter drives, shortchanged Democratic precincts when they allocated voting machines and illegally derailed a recount that could have given Kerry the presidency…. In Warren County, GOP election officials even invented a nonexistent terrorist threat to bar the media from monitoring the official vote count….

In what may be the single most astounding fact from the election, one in every four Ohio citizens who registered to vote in 2004 showed up at the polls only to discover that they were not listed on the rolls….

”Ohio was as dirty an election as America has ever seen,” Lou Harris, the father of modern political polling, told me. ”You look at the turnout and votes in individual precincts, compared to the historic patterns in those counties, and you can tell where the discrepancies are. They stand out like a sore thumb….”

…In the battle for Ohio, Republicans had a distinct advantage: The man in charge of the counting was Kenneth Blackwell, the co-chair of President Bush’s re-election committee. As Ohio’s secretary of state, Blackwell had broad powers to interpret and implement state and federal election laws — setting standards for everything from the processing of voter registration to the conduct of official recounts. And as Bush’s re-election chair in Ohio, he had a powerful motivation to rig the rules for his candidate. Blackwell, in fact, served as the ”principal electoral system adviser” for Bush during the 2000 recount in Florida, where he witnessed firsthand the success of his counterpart Katherine Harris, the Florida secretary of state who co-chaired Bush’s campaign there.

My sister, living in Ohio, remarked: “Ohio Republicans as a whole have put on an amazing display of corruption for the past year or more…” while another Ohio-dwelling friend said, “From where I sit…Ken Blackwell is the Darth Vader of Ohio politics…. How #$@&ing long can we waste our energy on the bullcrap issues and ignore the fundamental disintegration of our physical, cultural, intellectual, and spiritual infrastructure?”

You must of course draw your own conclusions. I personally am convinced that there was more than enough chicanery in the Ohio elections alone to account for the outcome of the 2004 election. Regular readers know well enough by now what I think about the current administration. But more important even than the consequences we face down the road from current policy is the risk of losing our democratic process altogether from rigged elections.

I’ll just end by quoting Robert Kennedy’s closing paragraphs:

If the last two elections have taught us anything, it is this: The single greatest threat to our democracy is the insecurity of our voting system. If people lose faith that their votes are accurately and faithfully recorded, they will abandon the ballot box. Nothing less is at stake here than the entire idea of a government by the people.

Voting, as Thomas Paine said, ”is the right upon which all other rights depend.” Unless we ensure that right, everything else we hold dear is in jeopardy.

Die, Big Bird, Die!

posted in: public affairs 0

They just can’t leave Big Bird alone, can they? This is from last Friday’s Washington Post:

A House subcommittee voted yesterday to sharply reduce the federal government’s financial support for public broadcasting, including eliminating taxpayer funds that help underwrite such popular children’s educational programs as “Sesame Street,” “Reading Rainbow,” “Arthur” and “Postcards From Buster.”

In addition, the subcommittee acted to eliminate within two years all federal money for the Corporation for Public Broadcasting — which passes federal funds to public broadcasters — starting with a 25 percent reduction in CPB’s budget for next year, from $400 million to $300 million.

Are they just afraid of large, yellow avian life-forms that talk funny? Or, hmm, you don’t suppose they’re afraid of balanced public-affairs broadcasting, do you? PBS still produces some of the best programming on TV—not just children’s programming and public affairs, but science and the arts as well—and NPR remains the best source of varied and balanced public-affairs talk radio. Here we go around the block again to save Big Bird!

Cat Chases a Bear Up a Tree, and Other Interesting Stories

posted in: quirky, science 0

The following items come to me courtesy of other people—I don’t have the time to surf the web and find this stuff!

Cat trees bear…
Our title story is one of the odder ones I’ve heard recently. But the picture sure looks real. In West Medford, NJ, a black bear was treed by a territorial tabby cat named Jack. (If you click on the picture, you can see an enlargement that shows Jack a little more clearly.) Can we trust AP that it’s true? I dunno—it’s too good a story not to be.

Teenagers turn a “teenager-repellent” sound into a ring-tone…
This is from the NY Times: “In that old battle of the wills between young people and their keepers, the young have found a new weapon that could change the balance of power on the cellphone front: a ring tone that many adults cannot hear.” Very handy in classrooms where cell phones are forbidden—a tone inaudible to the teacher, which signals an incoming text message or email.

“The cellphone ring tone that she heard was the offshoot of an invention called the Mosquito, developed last year by a Welsh security company to annoy teenagers and gratify adults, not the other way around… It was marketed as an ultrasonic teenager repellent, an ear-splitting 17-kilohertz buzzer designed to help shopkeepers disperse young people loitering in front of their stores while leaving adults unaffected.”

The Mosquito depended on the fact that most adults have already lost enough high-frequency hearing that they simply wouldn’t hear the sound, while to teenagers it would be an irritant.

We tried it out here. (You can download an MP3 of the sound from the NY Times page.) My wife played it on her Mac laptop, and I couldn’t hear it, while my daughter said, “Sure, I can.” Then I played it on my PC laptop, with the volume all the way up, and I could hear it as a faint, unpleasant keening sound. My daughter said, “Augghhh!” and immediately left the room. (My other daughter said she found it unpleasant, but not enough to work as a dispersant.)

New Careers for Dogs…
This also from the NY Times. Dogs have now been trained to sniff out bedbugs, cancer in people, cows in heat, and potentially pirated DVDs in cargo containers, among other things. Good boy!

Droids on the International Space Station…
Remember the trainer-droid in Star Wars—the little hovering robot that Luke had trouble whipping with his light saber until he finally “used the Force”? Well, from NASA’s Space News comes this:

“Six years ago, MIT engineering Professor David Miller showed the movie Star Wars to his students on their first day of class. There’s a scene Miller is particularly fond of, the one where Luke Skywalker spars with a floating battle droid. Miller stood up and pointed: ‘I want you to build me some of those…’ So they did. With support from the Department of Defense and NASA, Miller’s undergraduates built five working droids. And now, one of them is onboard the International Space Station.”

It doesn’t actually fire little laser beams. But it does maneuver, and they’re working on teaching them to rendezvous in space. Hm, I feel an urge to pit one against my Roomba.

World Wind from NASA

posted in: quirky, space 0

Okay, enough with the politics for a while. I’ve got something cooler. It’s free software from NASA, and it’s called World Wind.

By now, I expect most of you know about Google Earth. It’s a sort of World Wide Earth browser that lets you see the surface of the Earth from satellite imagery and turn it all around and zoom in close enough and clearly enough that, depending on where you live, you may be able to pick out your own house and tell whether you (or at least your cars) were at home when the photo was taken. In fact, here is a picture of my house, taken from Google Earth.


You can’t quite see how cracked the driveway is, but I can tell it was taken before we rebuilt the deck, so it must be a few years old. (That faint fuzzy patch to the right of the deck that looks like a giant grey dandelion puff is actually a pretty good sized pin-oak tree.) If they get a little better with it, we could use it to inspect our roofs and chimneys! My office window is high on the end of the house overlooking the deck. You can’t quite see me hard at work.

World Wind from NASA is similar, but different. You can rotate and zoom in, and add all sorts of fancy overlays—but you can do it not just with Earth, but with the Moon, Mars, Venus, and Jupiter. Also the stars. (And someone added a plug-in for the Death Star.) The resolution of Earth isn’t as fine, but I like it better for the planets, anyway. For Mars and Venus, it’ll show you where all the spacecraft have landed. (I was amazed how many there were.) Here are two pix of Mars. You won’t see it here, but if you mouse over the icons, it’ll tell you the spacecraft names and dates. It also has a bunch of scientific overlays if you’re interested.

This second one is the landing site of the Opportunity robot buggy.

The software is Windows only, I’m afraid. And although I found the installation easy, I had to reinstall something called .NET framework from Microsoft before it worked. But the instructions are pretty clear if you speak even pidgeon-geek. Give it a try!*

*But if it breaks your machine (heh-heh), you didn’t hear about it from me!
