3 MAN CHESS variant in the round Pythagorean cup Cross section Cross section of a Pythagorean cup. A Pythagorean cup (also known as a Pythagoras cup, a Greedy Cup or a Tantalus cup) is a form of drinking cup that forces its user to imbibe only in moderation. Form and function[edit] A Pythagorean cup looks like a normal drinking cup, except that the bowl has a central column in it – giving it a shape like a Bundt pan in the center of the cup. When the cup is filled, liquid rises through the second pipe up to the chamber at the top of the central column, following Pascal's principle of communicating vessels. Common occurrences[edit] A Pythagorean cup sold in Crete A Pythagorean cup sold in Samos Hero of Alexandria (c. 10–70 AD) used Pythagorean cups as hydraulic components in his robotic systems.

Woody and Buzz Lightyear reimagined as badasses… If these updated versions of Woody and Buzz Lightyear by Panzer Vargas were in a live-action movie, what actors would play the parts? (via ToyCutter) Green Laser Erases Print: Scientific American Podcast Every year, about 10 million tons of paper winds up in American landfills and incinerators, which is not only wasteful but adds CO2 to the atmosphere. Recycling helps, but even that material has to be repulped and paper-ized before you can use it to print out that recipe you’ll never make. But what if you could wipe the page clean and use it again? Light amplification by stimulated emission of radiation to the rescue. A new study shows that laser light can erase the toner from a piece of printed paper. The approach appears in the Proceedings of the Royal Society A. Taking a page from the art-restoration handbook, scientists sampled a variety of light sources to see if any could be used to strip the ink from laser-printed documents without damaging or discoloring the paper. Such unprinters will probably run about 30,000 bucks, so they probably won’t catch on for home use. —Karen Hopkin [The above text is a transcript of this podcast.]
Wasps take shelter in zombie ladybugs If a ladybug's life were a horror film, this is how it would start: Scary string music. A close-up of the green-eyed face of a wasp. The sudden pierce of a stinger. The screen goes dark. Next, an establishing shot of our ladybug hero, sitting placidly on a leaf. This sordid tale isn't fiction for many ladybugs that fall victim to the parasitical wasp Dinocampus coccinellae. The research, published today (June 21) in the journal Biology Letters, finds that this protection comes at a cost: Larva that cocoon themselves to a living ladybug, as opposed to a dead one or to none at all, can expect fewer eggs of their own when they emerge as wasps. Ladybug horror The wasps' parasitical ways have been long noticed, and they aren't unique in the insect world. Nor is mind control very extraordinary for parasites. To test the idea, the researchers reared more than 4,000 ladybugs in the lab and let wasps lay their eggs in the unfortunate insects. Ladybug bodyguard Related on LiveScience:
The 8 Most Painful Torture Devices Of The Middle Ages Torture Devices Of The Middle Ages: The Saw Before the saw was given its perfunctory role to slice through wood and thick material, it was used to slice through humans for torture or execution. The victim would be held upside down, allowing the blood to rush to their head, and then the torturer would slowly start slicing them between their legs. With the blood contained in the head, the victim would remain conscious throughout most of the slicing, often only passing out or dying when the saw hit their mid-section. Painful Torture Devices: Breast Ripper Or The Spider For those women who were accused or adultery, abortion or any other crime, they were subjected to the painful torture of the breast ripper or the spider.
Celebrity Commercials Before They Were Famous It wasn't always red carpets, box office blowouts, marquee lights and free swag for these celebs. No, eventual head turners and riot causing superstars got their starts hocking pizza and Pringles, 'Doing the Dew,' and keepin' it poppin' with Bubble Yum. You'd barely recognize Morgan Freeman (if not for his voice) touting Listerine as a wire repairman or a tiny Sarah Michelle Gellar wagging a disapproving finger at McDonalds' Burger King-inferior meat patties. From Evangeline Lilly's phone sex commercial to Paul Rudd's geek-tastic Super Nintendo spot, these celebs put the generation of the YouTube born, talent show made, instant stars to shame -- although they're the ones who may be hanging their heads low after these embarrassing videos make the rounds.

The threads on the jeans then will very effectively both fix any tiny bends in the blades that inevitably happen and will also sharpen the blades on your shaver cartidge. 2) How to make your teeth whiter Baking soda makes a good teeth whitener. 1.
The destructive culture of pretty pink princesses Girls the world over often go through a "princess phase," enthralled with anything pink and pretty — most especially the Disney princesses. When it happened to Peggy Orenstein's daughter Daisy, the contributing writer for the New York Times Magazine stepped back to examine the phenomenon. She found that the girlie-girl culture being marketed to little girls was less innocent than it might seem, and can have negative consequences for girls' psychological, social and physical development. Orenstein's exploration took her to Walt Disney World, the American Girl flagship store in New York City and a child beauty pageant. She details her quest in the new book, "Cinderella Ate My Daughter: Dispatches from the Front Lines of the New Girlie-Girl Culture" (Harper Collins, Jan. 25). LiveScience: How did you get inspired to write the book? Orenstein: I'm a mother, and I think that when you're an adult, you don't really notice what's going on so much in the world of kids' culture. In a word, yes.
Teaching Core Curriculum Content Through the Arts Teaching Core Curriculum Content Through the Arts Victoria R. Jacobs Merryl R. San Diego State University California State University San Marcos American Educational Research Association Annual Meeting April 1999 Montreal, Canada The second-grade classroom is darkened, like a cave. After this drama, this teacher commented that she felt her students finally understood what it means to be a night creature (vs. a day creature) and how a bat moves through the darkness using only sound and smell to find its baby. The fourth grade class is preparing to produce a play about nature in which the students will portray animals like tigers, coyotes, and rabbits. This lesson is the beginning of several lessons designed to use drama to help the students improve both their observation skills and their understandings about animal characteristics. The arts have long been known to deeply connect people with ideas and emotions (Dewey, 1959; Greene, 1991).
How to win Rock-paper-scissors every time I admit it. When I first heard there are actual tournaments for Rock-paper-scissors, sanctioned by the World Rock Paper Scissors Society, I laughed. I mean seriously, $50k to the winner of a game that requires no skill whatsoever? Absurd. Boy was I wrong. Rock-paper-scissors isn't just a silly game kids play or a way to decide who has to be the designated driver at parties. Males have a tendency to throw rock on their first try, inexperienced RPS players will subconsciously deliver the item that won previously, and paper is thrown least often, so use it as a surprise. 40 Belief-Shaking Remarks From a Ruthless Nonconformist | Raptitude.com - StumbleUpon If there’s one thing Friedrich Nietzsche did well, it’s obliterate feel-good beliefs people have about themselves. He has been criticized for being a misanthrope, a subvert, a cynic and a pessimist, but I think these assessments are off the mark. I believe he only wanted human beings to be more honest with themselves. He did have a remarkable gift for aphorism — he once declared, “It is my ambition to say in ten sentences what others say in a whole book.” A hundred years after his death, Nietzsche retains his disturbing talent for turning a person’s worldview upside-down with one jarring remark. Even today his words remain controversial. Here are 40 unsympathetic statements from the man himself. 1. 2. 3. 4. 5. 6. 7. 8. 9. 10. 11. 12. 13. 14. 15. 16. 17. 18. 19. 20. 21. 22. 23. 24. 25. 26. 27. 28. 29. 30. 31. 32. 33. 34. 35. 36. 37. 38. 39. 40.
