The Duelity of Nature

Thanks to a post on my friend David’s blog, I just ran across Duelity. It tells two creation stories—one from Genesis, one from modern science—using contradictory visuals and verbiage.

The introduction to the site hints at the conceit:

“According to the records of the General Organization of Development labs [GOD] it took a mere six days to manufacture a fully-operational universe, complete with day, night, flora and fauna, and installing Adam as its manager to oversee daily functions on Earth.

“If thou shalt believe the Book of Darwin, [’tis] five billion years after The Big Bang that we behold what the cosmos hath begat: the magma, the terra firma, the creeping beaste, and mankind, whose dolorous and chaotic evolution begat the gift of consciousness. ”

You get the idea. What I find interesting is that the approach is mirrored not just in the language used but also in the imagery that tells the stories. The General Organization of Development flick uses the visual language of a corporate training video, while the Book of Darwin employs an illustration style that recalls renaissance prints and stained glass. Brilliant stuff, really, and particularly impressive when viewed side-by-side, with the separate narratives intertwined.

I would say that I kind of object to the final tag line, though: “Duelity is a split-screen animation that tells both sides of the story of Earth’s origins in a dizzying and provocative journey through the history and language that marks human thought.” “Both sides”? As if there were only two…

Mars versus HTML


What started out as an impassioned diatribe turns out to be a mere complaint about HTML…

I get press releases in my email. They have URLs. I follow those URLs and (once in a while) end up writing about the press releases on my blog. So, this morning, I received “ESA: Mars Express watches a dust storm engulf Mars,” which pointed me to a page on the ESA site that featured the three images above, inset at different points in the article, and described (from left to right) as, “a dust storm on Mars,” “temperatures in the Martian atmosphere,” and “Mars – thermal radiation spectra.” I clicked on the wee pictures, hoping to be linked to something—nada—and looked for a link to a page of graphics that might offer some explanation—nada y nada y nada.

My ire began to build. That’s an artist’s conception of a dust storm, not an actual image! It should be labelled as such! And those graphs, lacking any axes, any interpretation? Argh! Then I noticed the URL. “SEMPWD361AF_index_2.html”? Hmmm. I changed the “2” to a ”1,” and lo and behold,… A whole page about the images.

Then I remembered the typical ESA page-naming scheme. I changed the “1” to a ”0” and found exactly what I expected in the first place.

So what can I say now? Other than recommend the email notices include the top-level ”index_0.html” link? Well, I think the caption for the animated dust storm should clearly say “artist’s rendition.” And the abscissas in the temperature plot should match. Otherwise, I guess I just have to get started with my day…

Trailing APOD

I’m not the biggest fan of the Astronomy Picture of the Day (APOD), but today’s post is pretty kewl. What you see above is a time-lapse image of the sky (well, actually, 477 30-second exposures taken over a period of 4.3 hours) that reveals the apparent motion of the stars that results from Earth’s rotation. I’ve never seen a wide-angle image that shows the celestial equator crossing directly across the image: thus, the star trails in the upper left and lower right appear to arc in different directions. Neato.

The image was taken (and is copyrighted) by Koen van Gorp.

Antarctic Mysteries

An article in today’s New York Times describes new websites from NASA and from USGS, showing high-resolution imagery of Antarctica. Check it out now before it all melts away!

I have some quibbles with the operation of the USGS site (the Java applet behaves a little oddly, provides effectively no information about the location displayed, and shows a map of Antarctica surrounded entirely with white), but it holds promise. And the NASA site has some spiffy stuff…

The image above comes from the “Antarctic Mysteries” game, which presents several unidentified photos for the viewer to identify. As a “game,” well, it’s not the most compelling, but I imagine I’m not the only person who looks at the grid of pictures, wonders what such-and-such might be, then clicks on the link to find out. Abstract and unusual, the images seem quite compelling.

What I truly admire, however, is the little extra info that the site provides about each image. For example, the feature above is about 25 kilometers across, located at 79°S, 80°W. Even better, the description includes a note: “This image appears darker than bright white snow because it has been enhanced to make slight contrasts in the snow more visible.” Excellent! Now, that wasn’t so hard, was it? One itsy-bitsy little extra line of text? Good work, NASA!
