Physics News of the Week (September 29 – October 6)

| October 7, 2012 | 0 Comments

So it’s time to review what was going on in the world of science this week. The Nobel Prize announcements are rapidly approaching so there was a lot speculation about the physics prize.  Astronomers were not sleeping as well — a new black hole was found in the Milky Way galaxy. All of this and more will be reviewed in this weeks edition of “Physics News of the Week. And, as always, f you would like to read our previous news, visit the news archive.

1. Heisenberg’s Uncertainty Principle Broken… Sort Of (October 4)

At the Frontiers in Optics 2012 meeting new evidence pointing against the original Heisenberg’s uncertainty formulation will be presented by the group of researchers from Toronto.  The original principle of uncertainty, formed by Heisenberg, was formulated in terms of measurements affecting the system, however, later, the generalised version doesn’t concern measurements at all. The original formulation, according to researchers from Toronto university, is not completely accurate. The team’s results provide the first direct experimental evidence that a new measurement-disturbance relationship, mathematically computed by physicist Masanao Ozawa, at Nagoya University in Japan, in 2003, is more accurate.

2. New Black Hole Found in the Milky Way Galaxy (October 5)

NASA’s Swift satellite recently detected a rising tide of high-energy X-rays from a source toward the center of our Milky Way galaxy. This points towards the existence of a previously not known black hole. “Bright X-ray novae are so rare that they’re essentially once-a-mission events and this is the first one Swift has seen,” said Neil Gehrels, the mission’s principal investigator, at NASA’s Goddard Space Flight Center in Greenbelt, Md. “This is really something we’ve been waiting for.” For more infohead here.

3. 127th Birthday of Niels Bohr (October 7)

127 years ago today, October 7, one of the fathers of quantum mechanics, Niels Bohr was born. Among many great contributions to theoretical physics, Niels Bohr was also a great administrator, who founded the Institute for Theoretical Physics in 1920, which became home for many great quantum physicists.

4. Nobel Prize Predictions (October 7)

A great Japanese author who writes of love and isolation, physicists delving into “spooky” quantum physics and experts on economic inequality have all been tipped as possible Nobel Prize-winners ahead of the start to the annual awards next week.  Medicine, physics and chemistry laureates will receive their Nobels first in Stockholm next week, followed later by economics. However, the rumours are far ahead and everyone is trying to guess the next Nobel prize winners. The big question you might be having, is why Peter Higgs not among the most likely candidates for the prize this year. And the answer is simple, there’s usually a bit of a lag between a great discovery and the award of Nobel prize, which is natural, as it takes some time to research and fully confirm a discovery.
