On Earth all biology is subjected to gravity.
Similar to the way pavement, softened by a hot sun, will slow down a car, graphene—a one-atom-thick sheet of carbon with wondrous properties—slows down an object sliding across its surface.
The December GSA TODAY science article, "Unique geologic insights from “non-unique” gravity and magnetic interpretation,” is now online at www.geosociety.org/gsatoday/.
PerpetualGreen's Dynamic EnergySave System increases the effectiveness of all forms of renewable energy by an average of 25%.
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.
COLUMBUS, Ohio, Feb. 9, 2011 /PRNewswire/ -- Delta Energy Services, an industry-leading provider of energy management services in North America, today announced that it has formed a strategic alliance with Bergen Energi and Comerc Energia.
GRANTS PASS, Ore., Jan. 10, 2011 /PRNewswire/ -- In "Tidal Forces: A Different Theory," as presented at Caltech to the American Physical Society on Oct.
Itâ€™s an occurrence that happens so fast it cannot be followed by the human eye, however, researchers have solved the mystery of how cats lap liquids with such elegance.
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 distancesâ€”a scale at which exotic new details of gravity's behavior may be detectable.
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...
