Papers document history of frontier physics research COLLEGE PARK, Md., July 26, 2011 /PRNewswire-USNewswire/ -- The Niels Bohr Library and Archives of the American Institute of Physics (AIP), has digitized and released online the complete papers of renowned physicist Samuel A. Goudsmit (1902-1978). (Logo: http://photos.prnewswire.com/prnh/20100714/AIPLOGO) The papers, which occupy 39 linear feet of shelf space in the library and contain approximately 69,000 images, are now published...

Researchers have changed one of the most basic rules of quantum mechanics: observing light behaving as both a wave and a particle -- a "complementarity" rule that asserts that it is impossible to do, even though it is strictly both.In an experiment reported in the journal Science, researchers say the feat "pulls back the veil" on quantum reality in a way that was thought to be prohibited by theory.Quantum mechanics, a counterintuitive branch of physics that deals with atomic-scale...

Quantum mechanics is famous for saying that a tree falling in a forest when there's no one there doesn't make a sound. Quantum mechanics also says that if anyone is listening, it interferes with and changes the tree. And so the famous paradox: how can we know reality if we cannot measure it without distorting it? An international team of researchers, led by University of Toronto physicist Aephraim Steinberg of the Centre for Quantum Information and Quantum Control, have found a way to do just...

There is considerable interest in understanding transport and information pathways in living cells. It is crucial for both the transport of, for example, medicine into cells, the regulation of cell life processes and their signalling with their environment. New research in biophysics at the Niels Bohr Institute shows surprisingly that the transport mechanisms do not follow the expected pattern. The results have been published in the scientific journal Physical Review Letters. The researchers...

A new paper by University of Notre Dame physicist Boldizsár Jank³ and colleagues offers an important new understanding of an enduring mystery in chemical physics. More than a century ago, at the dawn of modern quantum mechanics, the Noble Prize-winning physicist Neils Bohr predicted so-called "quantum jumps." He predicted that these jumps would be due to electrons making transitions between discrete energy levels of individual atoms and molecules. Although controversial in Bohr's...

The Earth and Moon were created as the result of a giant collision between two planets the size of Mars and Venus. Until now it was thought to have happened when the solar system was 30 million years old or approx. 4,537 million years ago. But new research from the Niels Bohr Institute shows that the Earth and Moon must have formed much later "“ perhaps up to 150 million years after the formation of the solar system. The research results have been published in the scientific journal,...

Scientists funded by the Biotechnology and Biological Sciences Research Council (BBSRC) and the Wellcome Trust at the University of Birmingham have carried out "laboratory gunfights" to show that we move faster when we react to something in our environment than we do when we initiate the action ourselves "“ an idea inspired by cowboy movies but in reality more useful for avoiding oncoming traffic. The research is published today (3 February 2010) in Proceedings of the Royal Society B....

New research, which reconstructs the extent of ice in the sea between Greenland and Svalbard from the 13th century to the present indicates that there has never been so little sea ice as there is now. The research results from the Niels Bohr Institute, among others, are published in the scientific journal, Climate Dynamics.There are of course neither satellite images nor instrumental records of the climate all the way back to the 13th century, but nature has its own 'archive' of the climate...

A clock that is so precise that it loses only a second every 300 million years "“ this is the result of new research in ultra cold atoms. The international collaboration is comprised of researchers from the University of Colorado, USA and the Niels Bohr Institute at the University of Copenhagen and the results have just been published in the prestigious scientific journal, Science. An atomic clock consists of gas atoms captured in a magnetic field where they are held stationary with...

Rice experiment yields closest analog yet for classic atomic model Nearly a century after Danish physicist Niels Bohr offered his planet-like model of the hydrogen atom, a Rice University-led team of physicists has created giant, millimeter-sized atoms that resemble it more closely than any other experimental realization yet achieved. The research is available online in Physical Review Letters. Bohr offered the first successful theoretical model of the atom in 1913, suggesting that electrons...

Carl Friedrich Freiherr von Weizsäcker (June 28, 1912 "“ 28 April 2007) was German physicist and philosopher. He was the longest-living member of Werner Heisenberg's research team which investigated nuclear studies in Germany during World War II. Some argue whether he and the team willingly engaged in the development of a nuclear bomb for Germany, or if its failure was intentional because they did not want the Nazi regime to have nuclear weapons. Weizäcker was born in Kiel,...

Niels Henrik David Bohr (October 7, 1885 - November 18, 1962) was a Danish physicist. He made essential contributions to understanding atom structure and quantum mechanics. Born in Copenhagen, Denmark to Christian Bohr and Ellen Adler, Bohr got his doctorate at Copenhagen University in 1911. He then studied under Ernest Rutherford in Manchester, England. Based on Rutherford's theories, Bohr published his Bohr model about atom structure in 1913, introducing the theory of electrons...
