Pegasi, following the full-speed spin-up of gyro #2 yesterday. Each full-speed spin-up takes most of a day. Helium gas is flowed over the gyro for 90 seconds, and tests are run to ensure that the ...

The Gyro Spin Spectre Optical Levitating Gyro Spinner stands out as a marvel of engineering and design. This precision-machined gyroscope, crafted from stainless steel, the gyroscope spinning top ...

NASA’s Gravity Probe B (GP-B) mission has confirmed two key predictions derived from Albert Einstein’s general theory of relativity, which the spacecraft was designed to test. The experiment, launched ...

For the past three years a satellite has circled the Earth, collecting data to determine whether two predictions of Albert Einstein's general theory of relativity are correct. Saturday, at the ...

Toy gyroscopes can do all kinds of interesting tricks. The most mysterious one, precession, seems to defy gravity. By definition, precession refers to a change in the orientation of the rotational ...
