Geek of the Week

Hi all - I'm starting a new feature (occasional, I guess!) called "Geek of the Week".  The first, brilliant, entry was found while exploring Digg.com http://digg.com/, which is a Communist entity in the heart of the Capitalist system: a news site which is edited by popular vote!

This week's Geek of the Week is amazing - a detailed study of what would happen to a Cessna plane if it attempted to fly in the atmospheres of various planets in our solar system.


The plane looks like this:  We have to use an electric motor because gas engines only work near green plants. On worlds without plants, oxygen doesn’t stay in the atmosphere—it combines with other elements to form things like carbon dioxide and rust. Plants undo this by stripping the oxygen back out and pumping it into the air. Engines need oxygen in the air to run. (Also, our gasoline is MADE of ancient plants.)

The hard work has been brilliantly done by a human (presumably) called xkcd, and you can find it here:  http://what-if.xkcd.com/30/

xkcd discusses what would happen to Icarus on the planet Titan:           this is the best reason for a moon colony

As a true engineer (and optimist), he adds:  "But I've never seen the Icarus story as a lesson about the limitations of humans.  . I see it as a lesson about the limitations of wax as an adhesive. The cold of Titan is just an engineering problem. With the right refitting, and the right heat sources, a Cessna 172 could fly on Titan—and so could we."

xkcd also markets a "Map of Online", and stickers saying "Citation Needed" in authentic Wikipedia style. 

You can add the stickers to "subway ads, product packaging, textbooks, or `free kittens!' fliers".  My first nominee is a sticker I saw the other day (on a giant SUV, of course), which informed us that "The trouble with Socialism is that eventually you run out of other people's money".  You just have to shake your head in amazement; how would the common ownership of the means of production and the elimination of parasitic exploiters equate to "other people's money"?

[I think the next (ir)regular feature will have to be "Idiotic Bumper Sticker of the Week"!]

Nominations for that, or for "Geek of the Week" will be gratefully received!
