Scientists Offer New Insights Into Early Universe
2012-11-29 15:54:22

Lee Rannals for redOrbit.com — Your Universe Online Penn State University scientists using techniques from modern physics have developed a new understanding of the earliest eras in the history of the universe. The scientists now have an extended analyses that include quantum physics farther back in time than ever before, heading back to the very beginning. The new paradigm of loop quantum origins show that the large-scale structures we see in the universe evolved from...

Digital Encryption At The Quantum Level

Michael Harper for redOrbit.com — Your Universe Online Toshiba and Cambridge University have been working together to find a cheaper and more efficient way to protect networks from criminal thievery and spying. To find the answer, these two teams looked to quantum physics, landing on a solution which allows high-speed fiber cables to be just as secure as dedicated fiber optics lines. Though this advance will likely first appear in government and military networks, this method could...

Griffith Uni researchers lead light breakthrough Research physicists have demonstrated the first device capable of amplifying the information in a single particle of light without adding noise. The research collaboration, involving Griffith University, The University of Queensland and University of Science and Technology of China, was able to amplify the noisy quantum state of a single photon subjected to loss, without adding noise in the process; in fact, their amplification reduced...

Quantum Kiss Changes Color Of Space

April Flowers for redOrbit.com - Your Universe Online Our world is made of color, even the empty gaps have a color of their own. The findings of this study, published in the current issue of Nature, set a fundamental quantum limit on how tightly light can be trapped. The Cambridge team collaborated with scientists from the Donostia International Physics Center (DIPC), the Materials Physics Center in Donostia-San Sebastián (CFM) and the  University of Paris-Sud to...

Researchers Reveal New Method For Entangling Photons
2012-11-03 08:24:56

April Flowers for redOrbit.com - Your Universe Online A research team led by the University of Vienna has developed a new method for entangling single photons that gyrate in opposite directions. This is the first step towards entangling and twisting even macroscopic, spatially separated objects in two different directions, according to the team. The findings of this study have been published in the journal Science. Quantum physics is the theory of lightweight objects such as atoms or...

Looking Beyond Space And Time To Cope With Quantum Theory
2012-10-29 09:30:54

Centre for Quantum Technologies at the National University of Singapore Physicists have proposed an experiment that could force us to make a choice between extremes to describe the behavior of the Universe. The proposal comes from an international team of researchers from Switzerland, Belgium, Spain and Singapore, and is published today in Nature Physics. It is based on what the researchers call a 'hidden influence inequality'. This exposes how quantum predictions challenge our best...

A research team from the University of Bristol's Centre for Quantum Photonics (CQP) have brought the reality of a quantum computer one step closer by experimentally demonstrating a technique for significantly reducing the physical resources required for quantum factoring. The team have shown how it is possible to recycle the particles inside a quantum computer, so that quantum factoring can be achieved with only one third of the particles originally required. The research is published in...

Optical Vortex Beams Placed On Chip
2012-10-19 13:46:28

Lee Rannals for redOrbit.com — Your Universe Online Scientists have demonstrated integrated arrays of emitters of "optical vortex beams" onto a silicon chip for the first time. Light in these beams, as reported to the journal Science, does not propagate in straight rays, but instead travels in a spiral fashion in a hollow conical beam shape. The beams look like a vortex or cyclone, with its light rays "twisted" either left-handed or right-handed. The researchers wrote that...

Physics is a natural science involving the study of matter and its motion through space-time, along with related concepts such as energy and force. On a broader scale, it also involves the general analysis of nature, conducted in order to understand how the universe behaves. Physics is one of the oldest academic disciplines, perhaps the oldest through its inclusion of astronomy. Physics was part of natural philosophy until the Scientific Revolution in the 16th century, when the natural...

Open Systems & Information Dynamics
2012-05-17 15:20:56

Open Systems & Information Dynamics (OSID) is journal published by World Scientific. The aim of the Journal is to promote interdisciplinary research in mathematics, physics, engineering and life sciences centered around the issues of broadly understood information processing, storage and transmission, in both quantum and classical settings. Our special interest lies in the information-theoretic approach to phenomena dealing with dynamics and thermodynamics, control, communication,...

Foundations of Physics
2012-04-29 19:30:54

Foundations of Physics is a monthly-published journal devoted to the conceptual bases and fundamental theories of modern physics and cosmology, emphasizing the logical, methodological, and philosophical premises of modern physical theories and procedures. The journal publishes results and observations based on fundamental questions from all major fields of physics: quantum mechanics, quantum field theory, special relativity, general relativity, string theory, M-theory, cosmology,...

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...

Multiverse -- The term Multiverse was invented in December 1960, by Andy Nimmo, then vice chairman of the British Interplanetary Society, Scottish Branch, for a talk on the Everett many-worlds interpretation of quantum physics which had been published in 1957, to the branch. This was given in February 1961, and the word with its original definition, "an apparent universe, a multiplicity of which, go to make up the whole universe" was then first used. This was because the then dictionary...

  • A gigantic fictional humanoid alien god being described with a head resembling an octopus and dragon wings and claws, around whom an insane cult developed.
  • Pertaining to the mythos of Cthulhu and additional otherworldly beings created by H. P. Lovecraft or inspired by his writings and imitators.
This word was invented in 1926 by H.P. Lovecraft for his short story, 'The Call of Cthulhu.' 'Cthulhu' may be based on the word 'chthonic,' which in Greek mythology refers to the underworld.
