11 | The Bose-Einstein condensates in free fall |
|
|
|
ultracold atoms in an elevator ? It is now possible . Next step : the satellite …
I was sitting on a chair in the Patent Office in Bern when suddenly I had an idea: when a man is in free fall, he does not feel his own weight . I was amazed . This simple thought experiment made a deep impression to me and took me to the theory of gravitation .
Albert Einstein , Kyoto , 1922
This is the idea that Einstein founded the theory of general relativity : a man trapped in an elevator in free fall not clear if he does not feel its weight because the elevator in free fall , or because that it is jettisoned in space, weightless. In other words , we can not distinguish the gravity of another type of acceleration . Today , physicists wonder about the validity of this ” principle of equivalence ” in the quantum domain . Tim van Zoest , of the Leibniz University in Hanover, and his colleagues have developed a device that would allow them to test this principle on a Bose- Einstein.
Provided by quantum physics , this peculiar state of matter – thousands of atoms cooled to the point where they are all in the same quantum state – is produced in the laboratory for fifteen years: the atoms are cooled laser , then in a magnetic trap . Slow down , they cool down to a few billionths of a degree above absolute zero . The experimental usual fills a room full of vacuum chambers, large magnetic coils , tables and optical electronics.

8 | The quasars, galaxies babies |
|
|
|
Astronomers, including members of the Niels Bohr Institute, University of Copenhagen have managed to observe the most distant quasars in the primary universe, dating from about 800 million years after the Big Bang. Their discovery was published in the scientific journal Nature.
The existence of quasars have been discovered in the early sixties. It was thought that this was a particular form of stars, distant sources emit electromagnetic energy and radio waves. They were then called quasars, for quasi-stellar. The light they emit is however very different from that emitted by normal stars: it was discovered in the eighties it was gigantic black holes surrounded by a galaxy of the primary universe.
Black holes are stellar bodies whose mass is between 100 million and 10 billion times the Sun. A disk of gas and dust rotates around this huge black hole inside the ring rotating faster than the outside. This results in friction between these particles, which creates the heat and light. Near the black hole, these particles are heated so that they emit X-rays away from the center of the ultraviolet light, then visible, and finally infrared rays. Even if the radiation from very small places, the size of our solar system, they are so powerful they can be seen from afar.

1 | Installation of the parable of the Sardinia Radio Telescope |
|
|
|
Last Saturday, May 22, 2010, was uneventful the installation of the parable of one of the largest radio telescopes in the world: the SRT (Sardinia Radio Telescope). Pranu Located Sagun, based 35 km from Cagliari , south of Sardinia, the telescope will be inaugurated in December this year. It will be a unique structure in Europe and will monitor the activities of radio sources dispersed in the universe with a minimum wavelength of 3 mm, corresponding to 100 GHz.
