Perpetual Futility A short history of the search for perpetual motion. by Donald E. Simanek Popular histories too often present perpetual motion machines as "freaks and curiosities" of engineering without telling us just how they were understood at the time. They also fail to inform us that even in the earliest history of science and engineering, many persons were able to see the futility and folly of attempts to achieve perpetual motion. Sometimes a particular device comes to us with a label, such as "Bishop Wilkins' magnetic perpetual motion machine." Popular articles leave the impression that the inventor believed it was a perpetual motion machine. Bhaskara's Wheels. Villard de Honnecourt was born in the late 12th century and probably lived and worked in the north of France from 1225 to 1250. The most celebrated of his machine designs was for a perpetual motion wheel. Villard's diagram shows seven hammers, and he insisted on an odd (uneven) number of hammers, explaining 56. That's it.

Origins of the Ohio Valley Giants Revealed! Origins of the Ohio Valley Giants Revealed! Hundreds of giant human skeletons have been reported in Ohio. Who were they, where did they come from? The following hypotheses do not contradict current archaeological theories that conclude that, they do not know who the mound builders were, where they came from, nor where they went. The sudden influx of people of gigantic height in the Ohio Valley is due to the Celts migrating into the British Isles, from 1500-1200 B.C and ending the domination by the Beaker Peoples in England. At the same time, the Amorites were also being displaced from the eastern Mediterranean by the Hittites, Egyptians and Hebrews.

50 Drinking Games Guaranteed to Get You Hammered What’s more fun than hanging out with your friends, getting plastered, and making an ass of yourself?

This is the third part in a series by Scott Anthony, author of The Little Black Book Of Innovation. It sounds so seductive: a “culture of innovation.” The three words immediately conjure up images of innovation savants like 3M, Pixar, Apple, and Google--the sorts of places where innovation isn’t an unnatural act, but part of the very fabric of a company.

Time Will End in Five Billion Years, Physicists Predict Our universe has existed for nearly 14 billion years, and as far as most people are concerned, the universe should continue to exist for billions of years more. But according to a new paper, there's one theory for the origins of the universe that predicts time itself will end in just five billion years—coincidentally, right around the time our sun is slated to die. The prediction comes from the theory of eternal inflation, which says our universe is part of the multiverse. This vast structure is made up of an infinite number of universes, each of which can spawn an infinite number of daughter universes. (Related: "New Proof Unknown 'Structures' Tug at Our Universe.")

Sea urchin Taxonomy[edit] There is a wide diversity of shapes in sea urchins. This "slate-pencil sea urchin" (Heterocentrotus mamillatus), despite its big, wide spines, is a regular sea urchin and not a cidaroid: its spines are not covered with algae. Specifically, the term "sea urchin" refers to the "regular echinoids", which are symmetrical and globular, and includes several different taxonomic groups, including two subclasses : Euechinoidea ("modern" sea urchins, including irregular ones) and Cidaroidea or "slate-pencil urchins", which have very thick, blunt spines, with algae and sponges growing on it. The irregular sea urchins are an infra-classis inside the Euechinoidea, called Irregularia, and including Atelostomata and Neognathostomata.

14 Best Inventions Using Biomimicry in 2011 (Videos) © Ohio State University We love biomimicry news. There is something satisfying about the natural world telling us how to make our technology better, rather than the often-assumed other way around.

Ongs Hat: Gateway to the Dimensions! A full color brochure for the Institute of Chaos Studies and the Moorish Science Ashram in Ong's Hat, New Jersey. YOU WOULD NOT BE READING THIS ARTICLE if you had not already penetrated half-way to the ICS. You have been searching for us without knowing it, following oblique references in crudely xeroxed marginal samizdat publications, crackpot mystical pamphlets, mail-order courses in "Kaos Magick"—a paper trail and a coded series of rumors spread at street level through circles involved in the illicit distribution of certain controlled substances and the propagation of certain acts of insurrection against the Planetary Work Machine and the Consensus Reality—or perhaps through various obscure mimeographed technical papers on the edges of "chaos science"—through pirate computer networks—or even through pure syncronicity and the pursuit of dreams. In any case we know something about you, your interests, deeds and desires, works and days—and we know your address. Where is Ong's Hat?
