¿Dividir átomos? Eso parece sinónimo inamovible de la fisión nuclear y la radioactividad. Sin embargo, gracias a las exóticas condiciones físicas vinculadas a la mecánica cuántica, unos investigadores de la Universidad de Bonn en Alemania recientemente han mostrado cómo puede ser dividido un átomo individual en dos mitades separadas y luego ser devuelto a su estado original.

Aunque la palabra "átomo" significa literalmente "indivisible", las leyes de la mecánica cuántica permiten dividir átomos (de modo similar a lo que ocurre con los rayos de luz) y reunificarlos.

Las leyes de la mecánica cuántica permiten que, bajo las condiciones adecuadas, un objeto exista simultáneamente en varios estados. El equipo de Dieter Meschede del Instituto de Física Aplicada de la citada universidad ha logrado con éxito lo que puede describirse, en algunos aspectos, como mantener a un átomo individual simultáneamente en dos lugares a más de diez micrómetros de distancia. Ésta es una distancia enorme para un átomo. Después, el átomo fue devuelto a su estado original.

El equipo de Andreas Steffen y Andrea Alberti decidió intentar valerse de un "puente cuántico" al permitir que el átomo tocase átomos adyacentes mientras era dividido, de modo que ambas mitades estuvieran "conectadas".

Los frágiles efectos cuánticos sólo pueden aparecer a las temperaturas más bajas, del orden de unas pocas fracciones de grado por encima del cero absoluto, el cual está en la franja de los 273 grados centígrados bajo cero.

Los átomos tienen un espín que puede ir hacia dos sentidos. Dependiendo de la dirección, con un láser se puede mover el átomo hacia la derecha o hacia la izquierda. La clave está en que el espín del átomo puede estar orientado hacia ambas direcciones simultáneamente. Debido a esto, si al mismo tiempo se mueve al átomo hacia la derecha y hacia la izquierda, éste se dividirá.

    Throw three points just isn't the whole garage day-to-day work, and don't forget, Stephen curry is your team in assists along with steals, he averaged 6. 7 assists from the regular season, 14 in the league and the playoffs stephen curry shoes is actually averaging 9. 3 assists since the league the first! Let's imagine a graphic, 40 minutes per game inside Treasury, attack launched lots of times, there are always some ball he wasn't from the outside, but the golf ball inside, attracted a twice... What will happen subsequently? There was a man the guy can tell you the reply, curry shoes he called clay : Thompson, from the older state warriors, he made this year 211 3-pointers, finished third inside the league, and that 211 3-pointers, 68 hails from the assists of Stephen curry.

    12-13 time of year to contrast the car port and ray Allen in '05 -' 06 -- Allen into 269 3-pointers, and he could be the Seattle supersonics. In which year, Allen's 269 connected with 653 three-point shots, picture 41. 2%, as Stephen -- 272 of 600 photographs in his Arsenal, as high as 45. 3%; That year, Alan ball attack create 3 ratio is less than a quarter, compared with 38. 6% in database; That year, Allen's assists the telephone number 3. 7, less as opposed to Treasury for three aids. So the outline, the image of the alternative 3-pointers hand decrease the garage outline: he not just completed the sharpshooter qualifications, his teammates for his or her creation of free-throw possibilities into; He will also look for opportunities as well, through the ball breakthrough, stopped for no helps 3-pointer of shots. Moreover, he also can pass assists, "create" another glass pitcher - clay - Thompson! Not simply can catch vote, will likely urgent stopped, can develop more opportunities to other people, this star, unique! I am just kd shoes afraid, just use "striker" two words happen to be unable to define Stephen curry, also have to be in with a "great" rhetoric.
