The Wince-Inducing Wonder of Mallakhamb, India's Extreme Gymnastics

The Wince-Inducing Wonder of Mallakhamb, India's Extreme Gymnastics: "Called the 'mother sport of ancient India,' mallakhamb is where competitors traditionally jump on a pole and perform an impressive 90-second routine of jumps, flips and other wince-inducing moments."

Redesigning Sukkot in New York City

Redesigning Sukkot in New York City: "









As part of the Jewish harvest festival of Sukkot, many Jews build sukkot, huts that are reminders of the ancient Israelites' nomadic dwellings. My friend Josh Foer of Atlas Obscura co-organized a design competition in New York City to radically re-imagine these temporary structures while still following the traditional design and ritual constraints. Twelve finalists will build their high-concept sukkot in Union Square on September and 19 and 20. The 'People's Choice' winner will then be on view until October 2. All of the amazingly creative, avant-garde designs can now be viewed on the Sukkah City site. Seen here at top left is 'Gathering,' by Dale Suttle, So Sugita, and Ginna Nguyen, New York. Top right is 'Fractured Bubble' by Henry Grosman and Babak Bryan. Below those two finalists is one of the 600 entries, titled 'Hashkiveinu,' from my architecture student nephew Ari Pescovitz, Kyle Campbell. and Chad Gleason. I'm admittedly biased, but I dig their idea to use CNC machining and prefabrication to make their sukkot a kit. Congratulations all who entered! I'd be thrilled to enjoy a harvest meal in any of these marvelous shelters.

Babbage-esque mechanical computer chip

Babbage-esque mechanical computer chip: "Over at Submitterator, markarayner informs us that engineers at Case Western Reserve University developed a mechanical version of a key component of digital circuits for computers. Their mechanical inverter, the basis for many logic gates, is built from nanoscale levers instead of the transistors patterned onto traditional chips. The research was funded by the US Defense Advanced Research Projects Agency (DARPA) who are after electronics that aren't prone to failure under high heat, like that inside a jet or rocket engine control system. Te-Hao Lee and colleagues published their work in the current issue of the journal Science. From New Scientist:

Like a telegraph operator's Morse key, these levers physically make and break contact to pass or block currents.

Application of a voltage makes the levers move under electrostatic attraction. At 550 °C Lee's team managed to get the inverter to switch on and off 500,000 times a second – performing a computation with each cycle. The faster the switching speed, the zippier the computing. Lee predicts that switching speeds of a billion times a second (1 gigahertz) are possible. That might not sound fast by the standards of desktop PCs, which often run at speeds in excess of 2.5 gigahertz, but for control system applications it's more than adequate.
