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. Credited to Pythagoras of Samos, it allows the user to fill the cup with wine up to a certain level. 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.

Edward Wilson The classic article, published 2 decades ago by one of the world's great biologists & humanists Imagine that on an icy moon of Jupiter - say Ganymede - the space station of an alien civilization is concealed. For millions of years its scientists have closely watched the earth. Because their law prevents settlement on a living planet, they have tracked the surface by means of satellites equipped with sophisticated sensors, mapping the spread of large assemblages of organisms, from forests, grasslands and tundras to coral reefs and the vast planktonic meadows of the sea. The watchers have been waiting for what might be called the Moment. It was all but inevitable, the watchers might tell us if we met them, that from the great diversity of large animals, one species or another would eventually gain intelligent control of Earth. Darwin's dice have rolled badly for Earth. The human species is, in a word, an environmental abnormality. The rules have recently changed, however.

Worldwide map of nuclear power stations and earthquake zones | maptd Following the incidents at nuclear power plants in Japan after the earthquake I was wondering which power stations around the world are near active earthquake zones. With this in mind, I’ve created a map combining two sets of information: A heatmap of every 4.5+ magnitude earthquake since to 1973 – around 174,000 in totalThe location of 248 atomic energy plants, including numbers of reactors. Represented by blue markers. The seismic data are from the United States Geological Survey and the nuclear power station information the International Atomic Energy Agency. The map is built from two Google Fusion tables, here and here. To see the actual locations of the earthquakes you can toggle the heatmap off and display markers instead.

A Well-Planned Retirement - And no one even knows his name. Outside England's Bristol Zoo there is a parking lot for 150 cars and 8 buses. For 25 years, its parking fees were managed by a very pleasant attendant. The fees were £1 for cars ($1.40), £5 for busses (about $7). Then, one day, after 25 solid years of never missing a day of work, he just didn't show up; so the Zoo Management called the City Council and asked it to send them another parking agent. The Council did some research and replied that the parking lot was the Zoo's own responsibility. The City Council responded that the lot attendant had never been on the City payroll. Meanwhile, sitting in his villa somewhere on the coast of Spain (or some such scenario), is a man who'd apparently had a ticket machine installed completely on his own; and then had simply begun to show up every day, commencing to collect and keep the parking fees, estimated at about $560 per day -- for 25 years. And no one even knows his name.
