Pioneer 10 Pioneer 10 (originally designated Pioneer F) is an American space probe, weighing 258 kilograms, that completed the first mission to the planet Jupiter. Thereafter, Pioneer 10 became the first spacecraft to achieve escape velocity from the Solar System. This space exploration project was conducted by the NASA Ames Research Center in California, and the space probe was manufactured by TRW. Pioneer 10 was assembled around a hexagonal bus with a 2.74 meter diameter parabolic dish high-gain antenna, and the spacecraft was spin stabilized around the axis of the antenna. Its electric power was supplied by four radioisotope thermoelectric generators that provided a combined 155 watts at launch.

Photo by Sabah Arar/AFP/Getty Images Sometimes, the good guys win. In 2009, it came to light that a man named James McCormick was selling a device he claimed could detect hidden bombs. Clearly, something like this would have great military utility. The thing is, the detectors McCormick made didn’t work.

Japan Earthquake, 2 Years Later: Before and After - In Focus In a few days, Japan will mark the 2nd anniversary of the devastating Tohoku earthquake and resulting tsunami. The disaster killed nearly 19,000 across Japan, leveling entire coastal villages. Now, nearly all the rubble has been removed, or stacked neatly, but reconstruction on higher ground is lagging, as government red tape has slowed recovery efforts. Locals living in temporary housing are frustrated, and still haunted by the horrific event, some displaying signs of post-traumatic stress disorder. Collected below are a series of before-and-after interactive images. Pythagorean Theorem and its many proofs Professor R. Smullyan in his book 5000 B.C. and Other Philosophical Fantasies tells of an experiment he ran in one of his geometry classes. He drew a right triangle on the board with squares on the hypotenuse and legs and observed the fact the the square on the hypotenuse had a larger area than either of the other two squares. Then he asked, "Suppose these three squares were made of beaten gold, and you were offered either the one large square or the two small squares. Which would you choose?"
