Alguien me podría decir de que va este video?(está en inglés

[tuzania]

Bueno, pido su ayuda por si alguien me podría decir qué es lo que explica el señor del vídeo en términos generales. Ya que no entiendo ni papa!

El link es: http://www.nature.com/nature/videoarchive/trickofthelight/

(solo darle al botoncito de play)


Se agradecería muchísimo.


Saludos!

Lo primero es que mi PC es tan "caquilla" que no puedo ver el video, aunque sí lo puedo oir, así que esto es lo que creo que dice:

Primero oigo a un nota que dice:

"In this (no se qué) nature, we enter the extraordinay world of quantum mechanics"

Luego oigo a una piba que dice:

"we start a light pulse (no sé qué) in one part of space and then we can revive it in a completely different part of space and send it back on each way, so that's kind of the, the, the short explanation"

Luego el nota creo que dice:

"At Harvard's University Department of Physics, professor (un nombre) has been working in a dazzling experiment in which light from a laser is (no sé qué) to a Bose-Einstein Condensate, a fluid which is chill out, believed, to the degree about absolute zero. When the light actually slows down to the speed of the (no sé qué), it starts to behave in the strangest way, a way which can only be describe in terms of quantum mechanics"

Luego habla la piba:

"It's extremely important for this experiment that we have Bose-Einstein Condensates, party (no sé qué) Bose-Einstein Condensates and party manipulate them very precisely with resonance laser (no sé qué) so we can kind of make these Bose-Einstein Condensates do exactly what we want, so we must (no sé qué) them (no sé qué).."

"And now, what is a Bose-Einstein Condensate? Well, it's something, for starters, that's very cold, we need these very cold atoms, and we use sodium atoms, we cool them with laser in our (no sé qué) down to a few millionth of the degree of actually zero, and actually (no sé qué) to a few billionth of the degree of actually zero.

So obviously, that's pretty freezing cold"(mañana sigo, que tengo sueño)

Muchas gracias mat!

Gracias a tu transcripción pude encontrar un artículo que habla sobre el experimento:

Relleno los huecos de mat con lo que yo entiendo que dice en esas partes:


In this webcasting of nature, we enter the extraordinay world of quantum mechanics.

We start a light pulse which extinguishes in one part of space and then we can revive it in a completely different part of space and send it back on each way. So that's kind of the, the, the short explanation.

At Harvard's University Department of Physics, professor Lene Hau (viene sobreimpreso en el video) has been working in a dazzling experiment in which light from a laser is fired into a Bose-Einstein Condensate, a fluid which is chill out, believed, to the degree about absolute zero. When the light actually slows down to the speed of a bicycle, it starts to behave in the strangest way, a way which can only be describe in terms of quantum mechanics.

It's extremely important for this experiment that we have Bose-Einstein Condensates, party (no sé qué) Bose-Einstein Condensates and party manipulate them very precisely with resonance laser beams so we can kind of make these Bose-Einstein Condensates do exactly what we want. So we massage them in effect with laser beams.

And now, what is a Bose-Einstein Condensate? Well, it's something, for starters, that's very cold, we need these very cold atoms, and we use sodium atoms, we cool them with laser in our lab down to a few millionth of the degree of absolute zero, and actually further down to a few billionth of the degree of absolute zero.
So obviously, that's pretty freezing cold.

Tu inglés es sobresaliente (el mío "cae en picado" por falta de práctica, voy a tener que irme al extranjero un par de meses a recuperarlo )

[gdl]

Basta ver las películas en inglés y sin subtítulos. Se mantiene la práctica y se ejercita el oído.

Buena idea, pero dado que las únicas veces que veo películas es con mi novia y a ella no creo que "le guste la idea"........va a ser complicado. (Tendré que sacar tiempo para ver películas yo sólo....ufff, eso en mi casa va a ser complicado, no me dejan libre ni la tele .....)
