Physics Quantum measurements leave Schrödinger's cat alive Just a peek Schrödinger's cat, the enduring icon of quantum mechanics, has been defied. By making constant but weak measurements of a quantum system, physicists have managed to probe a delicate quantum state without destroying it – the equivalent of taking a peek at Schrodinger's metaphorical cat without killing it. The result should make it … 51¶¯Âþ

Physics The surprise theory of everything (Images: Yosuke/Imagezoo/Getty Images) AS REVOLUTIONS go, its origins were haphazard. It was, according to the ringleader Max Planck, an "act of desperation". In 1900, he proposed the idea that energy comes in discrete chunks, or quanta, simply because the smooth delineations of classical physics could not explain the spectrum of energy re-radiated by an absorbing … Features

Enigma Number 1719 Taking averages I have before me a pile of nine counters numbered one to nine. I take two counters from the pile and write down the average of the numbers made by arranging them in two ways, that is in their original order and reverse order. I then take a third counter from the pile … Regulars
Feedback: In fruitloopery's house are many mansions In fruitloopery's house are many mansions "SOME of the notions that NES® is based on are quantum entanglement, information transfer and priority order..." Given that NES stands for Nutri-Energetics System®, can we guess what sort of stuff follows? Oh, yes, we can. "NES might be the first biotechnology that took into account the entanglement of … Regulars
