RAP del LHC del CERN

El anuncio del LHC (Gran colisionador de hadrones) fue acompañado de este


a cargo de jóvenes participantes en el proyecto. Tiene el mérito de constituir una descripción abreviada del proyecto y de los componentes del artefacto. A pesar del tiempo transcurrido sigue teniendo vigencia, no sólo por lo que de refrescante tiene la música y la puesta en escena, sino porque el LHC, obligado a grandes lapsos de inactividad por razones de fallos de funcionamiento (comprensibles dado lo altamente complejo que es el equipo), se encuentra de hecho en su fase inicial.


Twenty-seven kilometers of tunnel under ground
Designed with mind to send protons around
A circle that crosses through Switzerland and France
Sixty nations contribute to scientific advance
Two beams of protons swing round, through the ring they ride
Til in the hearts of the detectors, theyre made to collide
And all that energy packed in such a tiny bit of room
Becomes mass, particles created from the vacuum
And then

LHCb sees where the antimatters gone
ALICE looks at collisions of lead ions
CMS and ATLAS are two of a kind
Theyre looking for whatever new particles they can find.
The LHC accelerates the protons and the lead
And the things that it discovers will rock you in the head.

We see asteroids and planets, stars galore
We know a black hole resides at each galaxys core
But even all that matter cannot explain
What holds all these stars together something else remains
This dark matter interacts only through gravity
And how do you catch a particle theres no way to see
Take it back to the conservation of energy
And the particles appear, clear as can be

You see particles flying, in jets they spray
But you notice there aint nothin, goin the other way
You say, My law has just been violated it dont make sense!
Theres gotta be another particle to make this balance.
And it might be dark matter, and for first
Time we catch a glimpse of what must fill most of the known Verse.
Because

Antimatter is sort of like matters evil twin
Because except for charge and handedness of spin
Theyre the same for a particle and its anti-self
But you cant store an antiparticle on any shelf
Cuz when it meets its normal twin, they both annihilate
Matter turns to energy and then it dissipates

When matter is created from energy
Which is exactly what theyll do in the LHC
You get matter and antimatter in equal parts
And they try to take that back to when the universe starts
The Big Bang back when the matter all exploded
But the amount of antimatter was somehow eroded
Because when we look around we see that matter abounds
But antimatters nowhere to be found.
Thats why

ALICE looks at collisions of lead ions
CMS and ATLAS are two of a kind

And the things that it discovers will rock you in the head.

The Higgs Boson thats the one that everybody talks about.
And its the one sure thing that this machine will sort out
If the Higgs exists, they ought to see it right away
And if it doesnt, then the scientists will finally say
There is no Higgs! We need new physics to account for why
Things have mass. Something in our Standard Model went awry.

But the Higgs I still havent said just what it does
They suppose that particles have mass because
There is this Higgs field that extends through all space
And some particles slow down while other particles race
Straight through like the photon it has no mass
But something heavy like the top quark, its draggin its ***
And the Higgs is a boson that carries a force
And makes particles take orders from the field that is its source.
Theyll detect it.

Now some of you may think that gravity is strong
Cuz when you fall off your bicycle it dont take long
Until you hit the earth, and you say, Dang, that hurt!
But if you think that force is powerful, youre wrong.
You see, gravity its weaker than Weak
And the reason why is something many scientists seek
They think about dimensions we just live in three
But maybe there are some others that are too small to see
Its into these dimensions that gravity extends
Which makes it seem weaker, here on our end.
And these dimensions are rolled up curled so tight
That they dont affect you in your day to day life
But if you were as tiny as a graviton
You could enter these dimensions and go wandering on
And they'd find you...

La mujer en el arte del retrato


La técnica del "morphing" produce resultados que no dejan de asombrar. En este caso, aplicada a la pintura y particularmente al retrato femenino, produce un bello resultado gracias también al resalte que le imprime la música de la Sarabanda de la Suite número 1 para chelo de Bach. Gocen pues de

Pues algo hubo de cierto en la historia de Newton y la manzana. Aunque no parece que le cayera sobre la cabeza. Por otra parte hay que tener en cuenta que Newton llevaba tiempo meditando sobre la atracción del Sol como responsable de las órbitas planetarias; la caída vertical de la manzana le sirvió de modelo para relacionar el problema de la gravedad terrestre con la atracción del Sol sobre los planetas, y generalizar así su ley de la atracción, enunciándola como una ley de validez universal.

La Royal Society acaba de publicar algunas noticias interesantes al respecto, basadas en citas de biógrafos tempranos:
