Belousov's Brew . A recipe for making spiraling patterns in chemical reactions. Equiangular spiral .
(or, "Size Is Everything") She studied it carefully for about 15 minutes. Finally, she spoke. "There's something written on here," she said, frowning, "but it's really teensy."
Genaille–Lucas rulers (also known as Genaille's rods ) is an arithmetic tool invented by Henri Genaille , a French railway engineer, in 1891. The device is a variant of Napier's bones . By representing the carry graphically, the user can read off the results of simple multiplication problems directly, with no intermediate mental calculations . [ edit ] History
My First Eight Drains by 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.
The universe is full of weird substances like liquid metal and whatever preservative keeps Larry King alive. But mankind isn't happy to accept the weirdness of nature when we can create our own abominations of science that, due to the miracle of technology, spit in nature's face and call it retarded. That's why we came up with... What do you get when you suspend nanoparticles of iron compounds in a colloidal solution of water, oil and a surfactant? Did you guess Zima? The real answer is ferrofluids, though you should be proud if you just knew what "surfactant" was.

Abstract The extraction of accurate self-motion information from the visual world is a difficult problem that has been solved very efficiently by biological organisms utilizing non-linear processing. Previous bio-inspired models for motion detection based on a correlation mechanism have been dogged by issues that arise from their sensitivity to undesired properties of the image, such as contrast, which vary widely between images. Here we present a model with multiple levels of non-linear dynamic adaptive components based directly on the known or suspected responses of neurons within the visual motion pathway of the fly brain. By testing the model under realistic high-dynamic range conditions we show that the addition of these elements makes the motion detection model robust across a large variety of images, velocities and accelerations.
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.
News August 8, 2011 06:05 AM ET Computerworld - Start-up Millenniata and Hitachi-LG Data Storage plan to soon release a new optical disc and read/write player that will store movies, photos or any other data forever. The data can be accessed using any current DVD or Blu-ray player. Millenniata calls the product the M-Disc, and the company claims you can dip it in liquid nitrogen and then boiling water without harming it.
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.
