Helfenbein/Yale University ====================================================================================================================== Yale physicists have given Schrödinger's famous cat a second box to play in, and the result may help further the quest for reliable quantum computing. Schrödinger's cat is a well-known paradox that applies the concept of superposition in quantum physics to objects encountered in everyday life. The idea is that a cat is placed in a sealed box with a radioactive source and a poison that will be triggered if an atom of the radioactive substance decays. Quantum physics suggests that the...

    Where did the idea of “millions of years” come from? All of our media outlets push evolution and “millions of years” ideas on the public. Even children’s cartoons reflect evolutionary philosophy! In an episode of the cartoon SpongeBob SquarePants, entitled “SpongeBob B.C.,” the narrator begins: “Ah, dawn breaks over the primordial sea. It is here that millions of years ago, life began taking its first clumsy steps out of the darkness, opening its newly formed eyeballs to stare into the blinding light of intelligence.” Unfortunately, large segments of the church have swallowed the millions-of-years evolutionary history hook, line, and sinker....

    Physicists seek to put one thing in two placesSept. 25, 2006 Special to World Science  Physi­cists say they have made an ob­ject move just by watch­ing it. This is in­spir­ing them to a still bold­er proj­ect: put­ting a small, or­di­nary thing in­to two places at once. It may be a “fan­ta­sy,” ad­mits Keith Schwab of Cor­nell Uni­ver­si­ty in Ith­a­ca, N.Y., one of the re­search­ers. Then again, the first ef­fect seemed that way not long ago, and the sec­ond is re­lat­ed. The gray sliv­er reach­ing from top to bot­tom, slanted in the im­age, is a na­no­me­chan­i­cal re­s­o­na­tor, a sub-mi­c­ro­s­co­pic de­vice...
