Physicist Holger Müller and his colleagues at the University of California, Berkeley (United States), have found a new way to measure time using cesium atoms. As explained in an article recently published in the American journal Science, with this method it is possible to tell what time it is using only the matter wave of a cesium atom and they refer to their method as a Compton clock.
In the course of 2012, the work of scientists in Spain gave headlines, opened news reports and featured on the covers of the best scientific journals, as highlighted by the SINC agency in its selection of the most outstanding research in science "made in Spain" .
German and Czech researchers discovered this year that 275 molecules are enough to initiate crystallization and the transition from liquid water to ice. If another 200 more are added, frozen water nanocrystals are already observed, as the scientists published in Science.
Every year, the editors and experts of the journal Science select the ten most outstanding scientific milestones of what has happened in the course of 2012. On this occasion, the first place has been for the discovery of the Higgs boson, which confirms the hypothesis about its existence formulated forty years ago and completes the standard model of physics, providing an explanation of how other fundamental particles obtain their mass.
When we shower, the plastic in the shower curtains is usually absorbed into the shower tray or bathtub and adheres to our body. This annoying phenomenon could be explained by the pressure difference that appears due to the fact that the air is lighter when it is humid or hot (inside the shower), and tends to rise, while on the other side of the curtain it is colder, drier. and heavy, so that it is shifted inward by the pressure difference.
Sand dunes hum in some areas of the planet, and their "melodies" - always a low sound, similar to a buzzing - have aroused human curiosity for centuries. Marco Polo spoke of them, and also Charles Darwin in his "Voyage of the Beagle". The sound is a soft hum at a frequency equivalent to the lower half of the musical range of a cello.
Last night the Ig Nobel prizes were awarded to the most absurd investigations of the year. Thus, the Ig Nobel in psychology went to the Dutch Anita Eerland and Rolf Zwaan and the researcher Tulio Guadalupe (Peru), for demonstrating that leaning to the left makes the Eiffel Tower in Paris appear smaller.
The Large Hadron Collider (LHC) has collided protons with lead ions for the first time. Until now, the LHC had only collided with equal particles (proton-proton), so the collision of protons against nuclei presents important technical challenges, according to the National Center for Particle, Astroparticle and Nuclear Physics (CPAN).
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.
