Genaille–Lucas rulers. History In 1885, French mathematician Édouard Lucas posed an arithmetic problem during a session of the Académie française.
Genaille, already known for having invented a number of arithmetic tools, created his rulers in the course of solving the problem. He presented his invention to the Académie française in 1891. The popularity of Genaille's rods was widespread but short-lived, as mechanical calculators soon began to displace manual arithmetic methods. Appearance My First Eight Drains. My First Eight Drainsby drainer-wannabe Ninjalicious Meters below the busy streets above, a hidden concrete utopia snakes its way from the downtown core out beyond the suburbs.
Concrete pipes conduct our urban stormwater to strange fringe areas known as forests, meadows, riverbanks and seashores — a gallery of horrors collectively known as nature. In these unholy "natural" areas, the ground is covered with neither cement nor asphalt, and rainwater is allowed to fall directly onto the ground and soak into the earth at its own pace. 7 Man-Made Substances that Laugh in the Face of Physics. The universe is full of weird substances like liquid metal and whatever preservative keeps Larry King alive. Here Is a Fence that Will Give You Nightmares. @The Fake Santa Claus: Are you talking about Berlin?
Because I saw cool stuff pretty much every where I went there. I suppose it's possible that everywhere I went was either a high-tourist or hipster neighborhood, but I did stir around a bit. @The Fake Santa Claus: Bergmannstrasse is Kreuzberg, which is both high-tourist and hipster. Also has a huge Turkish community (at least 12 years ago when I lived there). @MissNormaDesmond: Yes. @waffles! Site.swf (application/x-shockwave-flash Object) Haiku Forge - Moments Lost in Time.

Forbidden Knowledge TV. 10,000 Shipping Containers Lost At Sea Each Year…Here’s a Look At One. We lose 10,000 of these things every year!
(c) 2004 MBARI Right now, as you read this, there are five or six million shipping containers on enormous cargo ships sailing across the world’s oceans. And about every hour, on average, one is falling overboard never to be seen again. Start-up to release 'stone-like' optical disc that lasts forever. News August 8, 2011 06:05 AM ET Recordable optical media such as CDs, DVDs and Blu-ray discs are made of layers of polycarbonate glued together.
One layer of the disk contains a reflective material and a layer just above it incorporates an organic transparent dye. During recording, a laser hits the die layer and burns it, changing the dye from transparent to opaque creating bits of data. A low power laser then can read those bits by either passing through the transparent dye layer to the reflective layer or being absorbed by the pits.
Over long periods of time, DVDs are subject to de-lamination problems where the layers of polycarbonate separate, leading to oxidation and read problems. While the DVD industry claims DVDs should last from 50 to 100 years, according to the National Institute of Standards and Technology (NIST), DVDs can break down in "several years" in normal environments.
Flying. Flying is also fun and challenging.
You have to think and act in three dimensions. You have the freedom to move to a lot of new spots on the globe. You learn to examine and appreciate scenery and natural phenomena that you'd never be able or wouldn't bother to see from the ground. Charles Lindbergh put it best: "Science, freedom, beauty, adventure. " Sadly Lindbergh was, in addition to being a great aviator, a supporter of the Nazis.
