First transistor the size of an atom

In May 1995 the American physicists David Wineland and Chris Monroe of the National Institute of Standards and Technology in Boulder, Colorado, found that sometimes the impossible happens. In a sensational experience, they managed to make an atom appear at two different points of space and the same exact moment.
That does not mean that from now on you will be able to go to two shows at the very time, but there is evidence that the atom can be here and there in one split second. In some circumstances, this is exactly how nature works. Before Wineland and Monroe, was already known that the subatomic particles were capable of such a feat, but no one had shown that the effect could reach a whole atom. Will creatures like big cats could repeat the feat? Turn the page and discover what physicists have to say about this possibility.
Quantum mechanics is the branch of physics that studies atoms on the outside and inside. Built in the early decades of the century, it is great, the most useful of all scientific theories, fired. Today, almost everything depends on it, starting with domestic appliances such as television and computers, even the most refined instruments such as radar and electronic microscopes. Even more important, his equations was first explained the reactions of chemistry and biochemistry, the functioning of the stars and the whole universe. Anyway, this century has the face of quantum mechanics, in all fairness.
But neither the people really understand what it does. "I can say no to trick me that nobody understands quantum mechanics," wrote American Richard Feynman (1918-1988), one of the most brilliant scientists of this century, known precisely for explaining difficult concepts without complications. In one of his lectures, Feynman opened the game: "Let me tell you how nature works," he said. "But avoid getting asked, 'how can you be?", Or will end in a stalemate. Nobody knows why things are so. "
Shortly after inventing the new mechanics, its creators became suspicious of what they had done. One, the Austrian Erwin Schrödinger, said in 1935 that if he were to take seriously the laws of quantum would have to believe in the undead. To illustrate the statement, he devised a thought experiment in which a cat was locked in a metal box with a glass of poison and a piece of radioactive metal. After 1 hour, what happened to the animal? The answer, Schrödinger explained, depended on the metal. Emits radiation, the glass would break and poison liquidate the cat. If not, the cat would unscathed by the trap.
