A class of molecules 100 – 1,000 times more energetic than typical has been discovered by Dr. Young K. Bae, a physicist at Y.K.

A group of researchers from MIT has developed a new algorithm for gauging the rotation of objects in space using only visual information.

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.

Infolytica Corporation has released the newest versions of its simulation suite of software: MagNet, ElecNet, ThermNet and OptiNet.

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.

Magnetic devices like hard drives, magnetic random access memories (MRAMs), molecular magnets, and quantum computers depend on the manipulation of magnetic properties.

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.

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...
