Physics News of the Week (September 22-29)

| September 29, 2012 | 0 Comments

In the second edition of the “Physics News of the Week” we will once again review the events that happened in the world of physics throughout the last week. There has been a number of really important events in the world of science, which I’m going to review briefly, so sit back and enjoy.

1. Thirteenth Volume of Einstein’s Papers Released (September 25)

Albert Einstein is perhaps the most known scientist of all time, thus it’s natural that there are thousands of books and documentaries about hit. However, not all is known about this enigmatic personality, as there are many mysteries and misinterpretations related to life of Einstein. Fortunately, a huge amount of papers, both research related and personal (letters, travel journals and so on) are saved and open for public. The 13th volume of Einstein’s personal papers was released to public on September 25. This volume tells the story of Einstein’s personal life back in the year 1922, when he was awarded the Nobel prize in physics, his travel through Japan, Palestine and Spain and more.

“This latest volume is extraordinarily rich, and illuminates in great detail Einstein’s scientific work and his exchanges and collaboration with many scientists in Europe, Japan, and the U.S.,” says Diana Kormos-Buchwald, the general editor of the series, a professor of history at Caltech, and the director of the Einstein Papers Project.

2. The Violation of Time-Reversal Symmetry (September 27)

One of the most important news in the world of physics this week was the confirmation of the time-reversal symmetry violation in particle physics. Predicted half a century ago, time-reversal asymmetry in particle physics has only now been clearly demonstrated. The weak interactions of elementary particles have long been known to be asymmetric under CP, the combined operation of parity P and charge conjugation C, the replacement of particles by their antiparticles. But only now has the first clear, direct evidence of Tviolation been reported in the PEPII electron–positron collider at SLAC. For more information click here.

The periodic table might just get bigger after a new discovery in Japan

3. New Element Possibly Discovered (September 28)

Physicists at the RIKEN Nishina Center for Accelerator-Based Science in Wako, Japan, claim to have produced convincing evidence that they’ve successfully made a new superheavy atom, element 113, by bombarding bismuth atoms with zinc in a particle accelerator. If the results are confirmed, the periodic table will become a little bigger, with an addition of the 113 element. Researchers had claimed to produce such atoms previously—some periodic tables currently list element 113 as Ununtrium (Uut), a temporary name for the synthetic element, however only the previous results seem to be conclusive.
