(Phys.org) -- For the first time, physicists have experimentally demonstrated the interaction of two motionless light pulses. Because the stopped light pulses have a long interaction time, it increases the ... A research team lead by Professor Martin Wegener at the Karlsruhe Institute of Technology has succeeded in realizing a new material class through the manufacturing of a stable crystalline metafluid, a pentamode ... (Phys.org) -- In the natural world, it seems randomness is all around. Walk through a forest for example and it appears completely random, despite the fact that natural patterns emerge at almost every turn. ...

Microscopic light beams that turns corners could make curving incisions in the body and improve the way microscopic components are carved and transported The clock's tick traversed an optical fibre 900 km long, paving the way for a network of synched clocks that could test Einstein's theory of gravity The multiverse-delving potential of quantum computing could become possible with a device that welds two existing technologies using the power of sound A simulation of the Nobel-prizewinning decay of a kaon into two pions could help explain why the universe contains so much more matter than antimatter
It is straightforward to determine the size of the Earth and the distance to the Moon without using a telescope. The methods have been known since the third century BCE. However, few astronomers have done this measurement from data they have taken. We use a gnomon to determine the latitude and longitude of South Bend, Indiana, and College Station, Texas, and determine the value of the radius of the Earth to be R earth = 6290 km, only 1.4% smaller than the known value.
