National Institute of Standards and Technology (NIST) By combining advanced mathematics with high-performance computing, scientists at the National Institute of Standards and Technology (NIST) and Indiana University (IU) have developed a tool that allowed them to calculate a fundamental property of most atoms on the periodic table to historic accuracy—reducing error by a factor of a thousand in many cases. The technique also could be used to determine a host of other atomic properties...

Engineer and author Dean Walker has done what many other notable scientists, including such greats as Newton and Einstein, were unable to do: mathematically prove the cause of gravity. Walker's latest work, Gravity Fields of Energy, explains why gravity only mimics an attractive force and proves the theory with relatively simple mathematics. Hyde Park, Vermont (PRWEB) June 12, 2014 Walker builds upon the works of Galileo, Newton, Einstein, and most recently the work of Joseph Taylor...

Ecole Polytechnique Fédérale de Lausanne Magnetic devices like hard drives, magnetic random access memories (MRAMs), molecular magnets, and quantum computers depend on the manipulation of magnetic properties. In an atom, magnetism arises from the spin and orbital momentum of its electrons. 'Magnetic anisotropy' describes how an atom's magnetic properties depend on the orientation of the electrons' orbits relative to the structure of a material. It also provides directionality and...

Researchers Develop 'Spinning Trap' To Measure Electron Roundness
2013-12-05 19:47:47

National Institute of Standards and Technology (NIST) JILA researchers have developed a method of spinning electric and magnetic fields around trapped molecular ions to measure whether the ions' tiny electrons are truly round—research with major implications for future scientific understanding of the universe. As described in the Dec. 6, 2013, issue of Science, the JILA team used their new spinning method to make their first measurement of the electron's roundness—technically, the...

Making Magnets With Ultra Cold Atoms

University of Hamburg Magnets have fascinated mankind for millenia. From the Greek philosophers to scientists of the modern era, which saw the rise of quantum mechanics, magnets have been pondered and investigated. Nowadays, they are not only intriguing oddities of nature, but also constitute crucial building blocks of modern technology: Ranging from data storage over medical instrumentation to transportation. And yet, to this day, they continue to puzzle scientists. A novel approach to...

Single-atom Bit Forms Smallest Memory In The World
2013-11-18 12:09:44

Karlsruhe Institute of Technology Control of the Magnetic Moment of Single Atoms Is the Key to Compact Data Memories and Quantum Computers One atom equals one bit: According to this design principle, we would like to construct magnetic data memories in the future. Presently, a compound of several million atoms is needed to stabilize a magnetic bit in a way that hard disk data are secure for several years. However, researchers from KIT have just made a big step towards a single-atom...

Heisenberg's Hunch Was Correct
2013-10-18 08:20:15

John P. Millis, PhD for redOrbit.com - Your Universe Online Students of physics are almost universally perplexed when they are first exposed to the paradoxical world of quantum mechanics. The reason the field is so difficult to wrap one’s mind around is that the behavior of quantum systems is fundamentally different from the macroscopic world in which we spend our lives. One of the guiding principles of the quantum world is a set of statements known as Heisenberg's error-disturbance...

Promising candidate for information processing with magnetic molecules Magnetic molecules are regarded as promising functional units for the future of information processing. An interdisciplinary team of researchers from Jülich and Aachen were the first to produce particularly robust magnetic molecules that enable a direct electrical readout of magnetic information. This was made possible by selecting the rare earth metal neodymium as the central building block of the molecule. The team's...

General Relativity -- General Relativity is the common name for the theory of gravitation published by Albert Einstein in 1915. According to general relativity the force of gravity is a manifestation of the local geometry of spacetime. Although the modern theory is due to Einstein, its origins go back to the axioms of Euclidean geometry and the many attempts over the centuries to prove Euclid's fifth postulate, that parallel lines remain always equidistant, culminating with the...

Escape Velocity -- An escape velocity is the minimum speed at which an object without propulsion can move away from a source of a gravitational field indefinitely if there is no friction. This definition may need modification for the practical problem of two or more sources in some cases. In any case, the object is assumed to be a point with a mass that is negligible compared with that of the source of the field, usually an excellent approximation. It is commonly described as the speed...

Word of the Day
  • One of a religious order living in a convent or in community; a monk: opposed to anchoret or hermit (one who lives in solitude).
  • A social bee.
This word comes from the Latin 'coenobium,' convent, which comes from the Greek 'koinobios,' living in community.
