Completing the story they started by creating synthetic magnetic fields,* scientists from the Joint Quantum Institute (JQI), a collaboration of the National Institute of Standards and Technology (NIST) and the University of Maryland, have now made atoms act as if they were charged particles accelerated by electric fields. Reported in the journal Nature Physics,** these synthetic electric fields make each atom in a gas act, individually, as if it were a charged particle, but collectively they...

GRANTS PASS, Ore., Jan. 10, 2011 /PRNewswire/ -- In "Tidal Forces: A Different Theory," as presented at Caltech to the American Physical Society on Oct. 30, 2010, Roy Masters revisits the theories describing the moon raising the tides by virtue of pull gravity combined with the moon's centripetal angular momentum. Masters shows that if gravity is considered the attractive interaction between individual bodies, then a working moon would have fallen to earth eons ago. Masters, founder of...

It's an occurrence that happens so fast it cannot be followed by the human eye.  However, researchers at MIT, Virginia Tech and Princeton University announced on Thursday that they have solved the mystery of how cats lap liquids with such elegance. Using high-speed cameras, the researchers found that domestic cats and larger felines like tigers use their tongues to delicately draw up water without breaking the surface of the liquid, harnessing a perfect balance between the physical...

A new experiment proposed by physicists at the National Institute of Standards and Technology (NIST) may allow researchers to test the effects of gravity with unprecedented precision at very short distances"”a scale at which exotic new details of gravity's behavior may be detectable.Of the four fundamental forces that govern interactions in the universe, gravity may be the most familiar, but ironically it is the least understood by physicists. While gravity's influence is...

Most animals don't think anything of breaking into a run: they switch effortlessly from walking to a high-speed bouncing run. But what about elephants? Their sheer size makes it impossible for them to bounce up in the air at high speeds. So how are high-speed elephants moving: are they running or walking? At a first glance, fast-moving elephants look as if they are walking, according to John Hutchinson from the Royal Veterinary College, UK. But closer analysis of elephant footfall patterns by...

Physicists have found a way to drastically prolong the shelf life of quantum bits, the 0s and 1s of quantum computers.These precarious bits, formed in this case by arrays of semiconductor quantum dots containing a single extra electron, are easily perturbed by magnetic field fluctuations from the nuclei of the atoms creating the quantum dot. This perturbation causes the bits to essentially forget the piece of information they were tasked with storing.A quantum dot is a semiconductor...

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...
