Skeptics’ Circle — call for submissions
by Sam Wise in Carnivalia, Site News
In case you didn’t read yesterday’s “Carnivalia” post closely, you might have missed the note that I’ll be hosting the “Skeptics’ Circle” blog carnival right here, next Thursday, the 17th of July.
So… if you write (or run across) any interesting critical-thinking sorts of blog posts between now and noon (wherever you live) next Wednesday, please drop me a line! BTW, the carnival’s ringleader has some good guidelines for SC-relevant material right here.

The scientific tourist #28 — Marston Mat
by Sam Wise in History, Sci / Tech Tourism, Technology
This week’s picture is from the San Diego Air & Space Museum, and shows a simple but very effective invention from World War II — Marston mat:
Marston mat (a.k.a., Marston matting, or PSP for Pierced Steel Planking) is one of those simple inventions that had a disproportionately large impact in real terms. It was developed in the U.S. shortly before our entry into WWII, for use in quickly building and repairing runways. It gained its nickname from the town in North Carolina where it was first made and tested late in 1941.
Typically, a piece of Marston mat was 10 feet long, 15 inches wide, and weighed about 66 pounds. The strips would interlock along their edges to form a continuous surface, which was then often covered with crushed rock or coral to form a flat surface. This technology allowed a runway 200 feet wide and 5000 feet long to be built in two days by a small team of engineers. Using this material, a bomb crater in a runway could also be repaired in 40 minutes by an unskilled labor party.

Casual Friday — Current events
by Sam Wise in Humor / Just for fun, Physics, YouTubing
Since today is independence day in the U.S., and barbecuing is a traditional activity for the day, I thought I’d give you a bit of video showing what is undoubtedly the most dramatic way I’ve ever seen to cook hot dogs — with a Tesla coil!
An outfit called the Nevada Lightning Laboratory demonstrated this… unusual approach to the culinary arts at Maker Faire ‘08, cooking a dozen hot dogs at a time using a 10-foot-tall Tesla coil. And for them, this is just a baby — they eventually want to build a pair of 120-foot-tall coils for lightning experiments.
