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. But stack the sheets and graphene gets more slippery, say theorists at the National Institute of Standards and Technology (NIST), who developed new software to quantify the material's friction. "I don't think anyone expects graphene to behave like a surface of a three-dimensional material,...

Earthquakes are some of the most daunting natural disasters that scientists try to analyze. Though the earth's major fault lines are well known, there is little scientists can do to predict when an earthquake will occur or how strong it will be. And, though earthquakes involve millions of tons of rock, a team of University of Pennsylvania and Brown University researchers has helped discover an aspect of friction on the nanoscale that may lead to a better understanding of the disasters....

Nanoparticulate flow in a curved pipe differs to that in a straight pipe, and is of scientific and technological interest. The length of flow path within a curved pipe is generally short, and the fluid experiences a centrifugal force which significantly changes the particle distribution both inside and downstream of the pipe. This phenomenon is more obvious when particle coagulation occurs. Prior to this study, nanoparticle migration in a rotating curved pipe with consideration of coagulation...

The next time you are in Pisa, try looking at its tower from a different perspective. Newton's laws of motion predict that an object will fall when its centre-of-mass lies beyond its base of support. But how does your brain know whether the tower will fall or not? Scientists from the Max Planck Institute for Biological Cybernetics in Tbingen, Germany recently reported in the journal PLoS ONE that although the physical laws governing object stability are reasonably well represented by the...

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...

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...

Bridging the classical/quantum divide Dartmouth researchers have discovered a potentially important piece of the quantum/classical puzzle "“ learning how the rules of physics in the quantum world (think smaller than microscopic) change when applied to the classical world (think every day items, like cars and trees). In a study published in the July 1 issue of the journal Nature, Associate Professor of Physics and Astronomy Alex Rimberg and his colleagues describe one example of the...

In a study published in the July 1 issue of the journal Nature, Dartmouth researchers describe one example of the microscopic quantum world influencing--even dominating, they say--the behavior of something in the macroscopic classical world. "One major question in physics has to do with the connection between the microscopic and macroscopic worlds," said Alex Rimberg, associate professor of physics at Dartmouth College. In the microscopic world, tiny sub-atomic particles such as photons and...

A team of nanotechnology researchers from the University of Pennsylvania and Columbia University has used friction force microscopy to determine the nanoscale frictional characteristics of four atomically-thin materials, discovering a universal characteristic for these very different materials. Friction across these thin sheets increases as the number of atomic layers decreases, all the way down to one layer of atoms. This friction increase was surprising as there previously was no theory to...

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...

The Seismometer is an instrument designed to measure the motions of the ground. This includes seismic waves generated by earthquakes, nuclear explosions, and other seismic sources. Records of these activities allow seismologists to map the interior of the Earth, and locate and measure the size of the different sources. There are also seismographs, which is sometimes used in place of the word seismometer. However, a seismograph is the older instrument in which the measuring and recording...

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...

  • A rich embroidered or brocaded silk fabric woven originally with a warp of gold thread.
'Baudekin' seems to be an alternative form of 'baldachin,' from the Italian 'Baldacco,' Baghdad, the city where the material was made.
