The Large Hadron Collider (LHC) at CERN, the world's largest particle accelerator, has managed to collide two beams of protons traveling at a speed of 3.5 TeV each at one o'clock today, obtaining an energy 7 TeV (teraelectronvolts), very similar to the one calculated to exist in the moments after the Big Bang, the cosmic explosion that started everything.
As of today, the Alba Synchrotron Light Laboratory comes into operation in Barcelona. It is a state-of-the-art particle accelerator that works like a gigantic microscope capable of uncovering the secrets of atoms and molecules.
Materials such as paper, paint or biological tissues are opaque because the light that passes through them is scattered in complex and seemingly random ways. A new French experiment has achieved that they behave practically like "transparent" glasses.
Tired of noisy neighbors turning on the television late at night? A team of scientists from the University of Hong Kong has found the ultimate solution. By placing panels made of latex and plastic, they have managed to silence and eliminate the annoying noises that penetrate the walls of houses and apartments.
Experiments carried out on airplanes or rockets had already shown that, under the influence of acceleration due to gravity, a clock decelerates its "ticking" with respect to a clock that remains on Earth, as predicted by the theory of relativity of Albert Einstein in 1915. Now, his hypothesis has been verified with a precision 10,000 times greater than any preceding test.
Scientists at the Brookhaven National Energy Laboratory in New York have recreated the hottest temperature ever since the Big Bang, 250,000 times hotter than that recorded at the center of the Sun and close to four trillion degrees. To achieve this they have used the Relativistic Heavy Ion Collider (RHIC) particle accelerator.
What happens if we put a soap in a microwave? What if we put a raisin in a soda bottle? Miguel Ángel Sabadell proposes two simple experiments to do at home that will surprise you and will reveal some of the basic principles of physics. In addition, you will learn curious historical details, such as that the first soda was invented by a certain Joseph Priestley in the 18th century.
The LHC or Large Hadron Collider at CERN has today become the world's most powerful particle accelerator after its two beams of protons have reached an energy of 1.18 teraelectronvolts.
Danni Büchner is invited to Sam Dylan's Halloween party. But the "Goodbye Germany" emigrant has no desire for many other party guests. And find clear words.
