"For the Discovery of the Accelerating Expansion of the Universe through Observations of Distant Supernovae"
The Royal Swedish Academy of Sciences awarded the 2011 Nobel Prize in Physics to Saul Perlmutter, an astrophysicist at the U.S. Department of Energy’s Lawrence Berkeley National Laboratory and a professor of physics at the University of California at Berkeley. Perlmutter heads the International Supernova Cosmology Project, which pioneered the methods used to discover the accelerating expansion of the universe. Dr. Perlmutter has been a leader in studies to determine the nature of dark energy.
Perlmutter shares the prize with Brian Schmidt and Adam Riess, leader of the High-z Supernova Search Team and first author of that team’s analysis, respectively, which led to their almost simultaneous announcement of accelerating expansion, which implies the existence of so-called dark energy, a mysterious force that acts to oppose gravity and increase the distance among galaxies. The nature of dark energy is unknown and has been termed the most important problem facing 21st century physics. It will continue to be studied by cosmologists, astrophysicists and particle physicists.
On learning of the award, Perlmutter said, “I am delighted, excited, and deeply honored. It’s wonderful that the Nobel Prize is being awarded for results which reflect humanity’s long quest to understand our world and how we got here. The ideas and discoveries that led to our ability to measure the expansion history of the universe have a truly international heritage, with key contributions from almost every continent and culture. And quite appropriately, our result – the acceleration of the...Read more...
Congratulations to Lawrence Berkeley National Laboratory(Berkeley Lab) as they celebrated their 80th anniversary on August 26.
Berkeley Lab is a member of the national laboratorysystem supported by the U.S. Department of Energythrough its Office of Science. Berkeley Lab is an incubator for ideas, innovations and products that help society and explain how the universe works; Their unclassified research portfolio includes renewable energy sources such as biofuels and artificial photosynthesis; energy efficiency at home, at work, and around the world; the ability to observe, probe, and assemble materials atom by atom; climate change research, environmental science and the growing connections between them; the chemistry and physics of matter and force in the universe — from the infinite to the infinitesimal; computational science and advanced networking to enable discovery and remote collaborations; and biological sciences for human health and energy research.
Berkeley Lab is highly respected for bringing science solutions to the world. Lab employees have been recognized as leaders in their fields, including:
· The Lab's scientific expertise has been recognized with 12 Nobel prizes
· Fifty-seven Lab scientists are members of the National Academy of Sciences
· Thirteen scientists have won the National Medal of Science
· Eighteen of the laboratory’s engineers were elected to the National Academy of Engineering
· Three of the Lab’s scientists were elected into the Institute of Medicine, and
· Berkeley Lab has trained thousands of university science and engineering students who are advancing technological innovations across the nation and around the world
Berkeley Lab was founded in 1931...Read more...
