Latest Angular momentum Stories
This article is the latest installment in a new series where redOrbit's in-house experts will answer questions submitted by you, the reader. This week's question: "Why does earth rotate?" Our resident expert explains.
The mechanism by which stars and black holes are formed in extreme cases of high mass density has puzzled astronomers since Johannes Kepler first laid out his laws of planetary motion some 400 years ago.
Vortex beams, rotating like a tornado, offer completely new possibilities for electron microscopy. A method of producing extremely intense vortex beams has been discovered at the Vienna University of Technology (TU Vienna).
A research team led by the University of Vienna has developed a new method for entangling single photons that gyrate in opposite directions.
The fabric of space-time around spinning black holes should impart a â€œtwistâ€ in the property of light called orbital angular momentum.
While those wonderful light sabers in the Star Wars films remain the figment of George Lucasâ€™ fertile imagination, light mills â€“ rotary motors driven by light â€“ that can power objects thousands of times greater in size are now fact.
Base running and base stealing would appear to be arts driven solely by a runner's speed, but there's more than mere gristle, bone and lung power to this facet of baseball â€” lots of mathematics and physics are at play.
Black holes are lighting up the Universe, and now astronomers may finally know how. New data from NASA's Chandra X-ray Observatory show for the first time that powerful magnetic fields are the key to these brilliant and startling light shows.
A gyroscope uses the principles of conservation and angular momentum to measure and maintain orientation. The mechanical gyroscope is a spinning wheel or disk whose axle is free to take any orientation. The gyroscope's high rate of spin allows for large angular momentum which makes the orientation changes much more responsive to a given external torque. There is also the electronic, microchip-packaged MEMS gyroscope, solid state ring laser and fiber optic gyroscope, as well as the extremely...
