Using literature written by Thomas Hardy, DH Lawrence and Herman Melville, physicists in Sweden have developed a formula to detect different authors' literary 'fingerprints'. http://www.physorg.com/news179651371.html Physics Thu, 10 Dec 2009 07:10:32 EST news179651371 (PhysOrg.com) -- One of the givens in physics is the weak equivalence principle. This principle has been considered solid since Einstein proposed that it is not possible to detect the difference between uniform acceleration and a uniform static gravitational field. The uniqueness of freefall allows uniform acceleration, even between masses that are different, according to Einstein's postulate in the theory of General Relativity. The weak equivalence principle is well established amongst the science community, but it has yet to be demonstrated completely. This is where Phillippe Bouyer at Laboratoire Charles Fabry de l`Institut d`Optique, Campus Polytechnique in Palaiseau, France, and his colleagues are attempting to go. http://www.physorg.com/news179481148.html Physics Tue, 08 Dec 2009 10:00:01 EST news179481148 (PhysOrg.com) -- Heat transport in the earth's mantle and in the atmosphere is probably not as effective as previously thought. http://www.physorg.com/news179053848.html Physics Thu, 03 Dec 2009 09:40:01 EST news179053848 (PhysOrg.com) -- The first stars in the universe may have been very different from the stars we see today, yet they may hold clues to understanding some of the mysterious features of the universe. These "dark stars," first theorized in 2007, could grow to be much larger than modern stars, and would be powered by dark matter particles that annihilate inside them, rather than by nuclear fusion. In the early universe, dark stars would have emitted visible light like the Sun, but today their light would be redshifted into the infrared range by the time it reaches us, and so dark stars would be invisible to the naked eye. http://www.physorg.com/news176457990.html Physics Tue, 03 Nov 2009 09:40:01 EST news176457990 A team of researchers from Pompeu Fabra University (UPF, Spain) has developed a system to identify common patterns in versions of songs, which will help to quantify the similarity of musical pieces. The technique, which appears in the New Journal of Physics, could be applied to analyse time series of data in other fields, such as economy, biology or astronomy. http://www.physorg.com/news175425825.html Physics Thu, 22 Oct 2009 10:24:35 EST news175425825 (PhysOrg.com) -- Since 2000, John Pendry's work on metamaterials has been at the van guard of efforts to create a perfect image - images with perfect resolution that can stem from light being moved in odd directions to create, among other tricks of the light, the illusion of invisibility. http://www.physorg.com/news173421185.html Physics Tue, 29 Sep 2009 05:33:33 EST news173421185 While the researchers can't promise delivery to a parallel universe or a school for wizards, books like Pullman's Dark Materials and JK Rowling's Harry Potter are steps closer to reality now that researchers in China have created the first tunable electromagnetic gateway. http://www.physorg.com/news169373038.html Physics Thu, 13 Aug 2009 09:04:48 EST news169373038 (PhysOrg.com) -- An astrophysics experiment in America has demonstrated how fundamental research in one subject area can have a profound effect on work in another as the instruments used for the Laser Interferometer Gravitational-Wave Observatory (LIGO) pave the way for quantum experiments on a macroscopic scale. http://www.physorg.com/news166941860.html Physics Thu, 16 Jul 2009 05:45:09 EST news166941860 (PhysOrg.com) -- Since 1994, when Peter Shor famously showed that a quantum computer could factor large numbers exponentially faster than any current classical algorithm, physicists have been investigating a variety of quantum computing schemes. However, truly scalable, controlled entanglement between many particles remains an elusive goal. In a recent study, physicists have proposed a new system that uses ultracold atoms trapped in an optical lattice to generate entanglement, which may be a promising method for realizing a scalable quantum computer due to the high degree of control it offers. http://www.physorg.com/news163250271.html Physics Wed, 03 Jun 2009 12:18:26 EST news163250271 (PhysOrg.com) -- Studies of climate evolution and the ecology of past-times are often hampered by lost information - lost variables needed to complete the picture have been long thought untraceable but scientists have created a formula which will fill in the gaps of our knowledge and will help predict the future. http://www.physorg.com/news162621293.html Physics Wed, 27 May 2009 05:41:02 EST news162621293 Quantum cryptography, a completely secure means of communication, is much closer to being used practically as researchers from Toshiba and Cambridge University's Cavendish Laboratory have now developed high speed detectors capable of receiving information with much higher key rates, thereby able to receive more information faster. http://www.physorg.com/news160274090.html Physics Thu, 30 Apr 2009 01:36:30 EST news160274090 (PhysOrg.com) -- When physicists entangle light, they usually use nonlinear crystals as the source. However, it`s difficult to control the entanglement generation process in a bulk crystal, and so scientists have been looking for a more fundamental source of entangled light. Now, they may have found a candidate: Bose-Einstein condensates. http://www.physorg.com/news158408510.html Physics Wed, 08 Apr 2009 11:22:27 EST news158408510 In quantum mechanics, a vanguard of physics where science often merges into philosophy, much of our understanding is based on conjecture and probabilities, but a group of researchers in Japan has moved one of the fundamental paradoxes in quantum mechanics into the lab for experimentation and observed some of the 'spooky action of quantum mechanics' directly. http://www.physorg.com/news155386974.html Physics Wed, 04 Mar 2009 11:03:23 EST news155386974 (PhysOrg.com) -- How many different sudokus are there? How many different ways are there to color in the countries on a map? And how do atoms behave in a solid? Researchers at the Max Planck Institute for Dynamics and Self-Organization in Göttingen and at Cornell University (Ithaca, USA) have now developed a new method that quickly provides an answer to these questions. http://www.physorg.com/news153588084.html Other Sciences Wed, 11 Feb 2009 15:22:12 EST news153588084 (PhysOrg.com) -- Originally, Moore`s Law described the number of transistors that can fit on an integrated circuit, which doubles approximately every 18 months. Now, a team of researchers from China has discovered that Moore`s Law can also describe the growth of the Internet. In a recent study, the researchers have predicted that the Internet will double in size every 5.32 years. http://www.physorg.com/news151162452.html Physics Wed, 14 Jan 2009 13:34:12 EST news151162452
