Even before von Lilienthal's sug- gestion, Etrich and Weis had patented a similar idea, but had abandoned it during construction. $ While no experiments were made, more mature consideration led to the ...

Decades in the making, a space probe that delves into Albert Einstein's general theory of gravitation remains grounded on Earth, caught in its own space-time continuum of technical snags, costly ...

For decades, Gravity Probe B quietly orbited Earth, trying to measure distortions in space-time that many believed were impossible to detect. This is the story of how NASA’s most precise experiment ...

Einstein's theory of gravity predicts that a rotating body, such as Earth, partially drags inertial frames along with its rotation. Scientists suggest a novel approach to measuring what is referred to ...

Two spacewalking astronauts hung science experiments on the outside of the space station’s new lab Friday and packed up a broken gyroscope for next week’s shuttle ride home. It was the third and final ...

Researchers have built a prototype fiber optic gyroscope for high resolution, real-time monitoring of ground rotations caused by earthquakes in the active volcanic area of Campi Flegrei in Naples, ...

THIS is an admirable little book suitable from every point of view as a present for a boy with a mechanical turn of mind. As the extended title indicates, the properties of the gyroscope are ...

When the final space shuttle mission launches later this year, two iPhone 4s will be on board. The iPhones will be running an experimental app called SpaceLab for iOS, designed by Odyssey Space ...
