Shelly Batts over at Retrospectacle just turned me on to this great show called Brainiacs. Here are a couple of fine videos starting off with a bit on alkali earth metals. I think Shelly is right, a British accent does lend an air of legitimacy. Kind of. Ahem. Don’t try this at home.
Try a YouTube search on Brainiac for more.
Several people have asked me recently about bubble solution formulations that improve on the regular dish soap stand-by. Take a look at this video to see some truly resilient, and even self-healing bubbles, along with the complete formulation!
Go forth and study bubble science!
Yes, my favorites are all irreverent, but I just can’t resist. Check out the growing collection at the Fine Art Photoshop Contest posted here, where you can also see the un-retouched originals.

Nikon just posted the results from their annual photo micro-graph competition
, and the winning images are simply stunning. One of the things that struck me about this year’s images was the significant leap in imaging technologies based on florescent DNA tagging combined with the use of confocal microscopy and volumetric tomography, even over last year’s images.
I really enjoyed browsing the Nikon site, going back in time, to see how science has advanced over even a couple of years. Clearer vision brings clearer insight, as they say; these images let us see things never seen before and witness processes first-hand that were mere hypothesis last year. More than insight, there is wondrous beauty and complexity in every image. Here are a few of my favorites from the 2007 gallery, but don’t miss browsing the rest on the home site.

No, this one is not animated. All the motion is happening in your head. If you don’t believe me, try covering most of the image with your hand or a piece of paper and only looking at a small part. You will see that no individual part of the image moves at all. It is only when you try to see the whole image that you notice motion.
So can any of you tell me how this works?

I just stumbled upon a fascinating article on Science in the Islamic World
, by a Pakistani scholar named Pervez Amirala Hoodbhoy at PhysicsToday.org. The article is mostly an exploration of the rise and fall of scientific inquiry in the Islamic states and the attendant root causes. There are clearly lessons here even for Western states that face rising tides of fundamentalism and calls for conformity, religious or otherwise.
The author doesn’t skip a beat as he calls out the similar US trends surrounding religious conservatives and their push for Creationism, Intelligent Design, curbs on genetic research, and so on.
But there are also some interesting tidbits on the technologies for daily living in the Islamic world, and how they have penetrated largely in support of the religions which otherwise strive to limit their spread.
“…while driving in Islamabad, it would occasion no surprise if you were to receive an urgent SMS (short message service) requesting immediate prayers for helping Pakistan’s cricket team win a match. Popular new Islamic cell-phone models now provide the exact GPS-based direction for Muslims to face while praying, certified translations of the Qur’an, and step-by-step instructions for performing the pilgrimages of Haj and Umrah. Digital Qur’ans are already popular, and prayer rugs with microchips (for counting bend-downs during prayers) have made their debut.”
A great read start-to-finish.
