(Phys.org)—"Spooky action at a distance," Einstein's famous, dismissive characterization of quantum entanglement, has long been established as a physical phenomenon, and researchers are keen to develop practical applications ...
(Phys.org)—A team of researchers from Austria, Germany and the U.K. has succeeded in building a model that shows the process that occurs when a liquid moves from a smooth state to one of turbulence inside of a pipe. In ...
We can't see the wind, but we can learn about it by observing things that are being blown about. And by studying changes in a comet's bright tail of gas and ions, scientists are on the trail to solving two big mysteries about ...
