LHC

...The experiments, smashing protons into each other, produced a few more subatomic particles known as pions and kaons than the team was expecting.

"The level is somewhat higher than the most popular models had predicted, and it looks like it is going to increase with energy a little bit more steeply than we expected," said Roland Gunter, a CMS collaboration scientist from the Massachusetts Institute of Technology in the US.

"I think it's not going to be a problem, but it is one of the many things that we need to know as we move toward searches for the most rare particles and new physics," he told BBC News.
...
"We'll know much more about that in two or three months when we look at the next higher energy of 7 TeV (trillion electron volts)."

All-Sky Milky Way Panorama 2.0

En 2001 pudimos admirar una visión panorámica de nuestra Via Lactea:




un trabajo enorme que reunió alrededor de 51 tomas.

Ahora 8 años mas tarde,



podemos quedarnos con la boca abierta con la segunda versión del proyecto que reúne alrededor de 3000 imágenes digitales.

mas del LHC!!!

De acuerdo a Analissa de Caro, ALICE, el detector de colaboración mexicana
acaba de registrar sus primera colision proton-proton.
 
y le dejo la noticia calientita:
 
The LHC is back

Geneva, 20 November 2009. Particle beams are once again circulating in the
world's most powerful particle accelerator, CERN*'s Large Hadron Collider
(LHC). This news comes after the machine was handed over for operation on
Wednesday morning. A clockwise circulating beam was established at ten
o'clock this evening. This is an important milestone on the road towards
first physics at the LHC, expected in 2010.

"It's great to see beam circulating in the LHC again," said CERN Director
General Rolf Heuer. "We've still got some way to go before physics can
begin, but with this milestone we're well on the way."

The LHC circulated its first beams on 10 September 2008, but suffered a
serious malfunction nine days later. A failure in an electrical connection
led to serious damage, and CERN has spent over a year repairing and
consolidating the machine to ensure that such an incident cannot happen
again.

"The LHC is a far better understood machine than it was a year ago," said
CERN's Director for Accelerators, Steve Myers. "We've learned from our
experience, and engineered the technology that allows us to move on.
That's how progress is made."

Recommissioning the LHC began in the summer, and successive milestones
have regularly been passed since then. The LHC reached its operating
temperature of 1.9 Kelvin, or about -271 Celsius, on 8 October. Particles
were injected on 23 October, but not circulated. A beam was steered
through three octants of the machine on 7 November, and circulating beams
have now been re-established. The next important milestone will be
low-energy collisions, expected in about a week from now. These will give
the experimental collaborations their first collision data, enabling
important calibration work to be carried out. This is significant, since
up to now, all the data they have recorded comes from cosmic rays. Ramping
the beams to high energy will follow in preparation for collisions at 7
TeV (3.5 TeV per beam) next year.

Particle physics is a global endeavour, and CERN has received support from
around the world in getting the LHC up and running again.

"It's been a herculean effort to get to where we are today," said Myers.
"I'd like to thank all those who have taken part, from CERN and from our
partner institutions around the world."

A press conference will be held at CERN, at the Globe of Science and
Innovation, at 2pm on Monday 23 November, and webcast at:

cannot guarantee that all questions will be answered.

LHC recargado!!!

El LHC se prepara para un nuevo intento:

"The first beam of the year is likely to be injected after mid-November..."

Bienvenido/ bienvenu/ welcome/willkommen//bienvenuto/bem-vindo

Vaya época para estar viviendo...

Cierto es que es tiempo de corrupción, pesimismo, crisis, terrorismo, hambruna, calentamiento global y mil otros sustantivos y adjetivos que caracterizan y califican nuestras aún frágiles y jóvenes relaciones económicas, sociales y morales. Dijera un buen pensador, el hombre es capaz de las pesadillas mas atroces pero también de los sueños mas bellos. Mi conclución: la vida es bella y el mundo apesta.
Así que en este nuevo contexto me atrevo a decir, ¡vaya época para existir!... nos encontramos en el umbral de una nueva gama de posibilidades y conocimiento; ante nuestro horizonte, mas allá de las atrocidades de nuestras pesadillas vueltas realidad, vamos completando y forjando nuevas formas de ver el Universo, regidos por todos los nuevos e inesperados descubrimientos que llegan día a día. Este blog, está dedicado a esta parte productiva de conocer el mundo, trataremos de que sea los mas objetivo que nuestra humanidad nos permita y hacerlo de la manera más multidisciplinaria e interdisciplinariamente posible, motivadondonos por solo el amor al arte (x3a),  nuestro arte de conocer, de preguntar y de explotar nuestra curiosidad.

Me disculpo anticipadamente por no dedicar mi tiempo a resolver los problemas serios que atañen y urgen a nuestra controvertida humanidad, perome haré en este espacio a un lado de ellos, para preguntar, conocer y apreciar este universo que nos rodea y quién sabe, quizás en el intento por descubrirlo, descubramos que nos ha dejado algo a nuestro vivir diario, a nuestro continuo pensar, a nuestra forma de ver  la vida... a nuestra forma de vivirla.

Sin más... bienvenidos a la Isla de Samos
