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...

Precession -- Precession is the phenomenon by which the axis of a spinning object "wobbles" when a torque is applied to it. The phenomenon is commonly seen in a spinning toy top, but all rotating objects can undergo precession. As a spinning object precesses, the tilt of its axis goes around in a circle in the opposite direction that the object is spinning. If the speed of the rotation and the magnitude of the torque are constant the axis will describe a cone, its movement at any...

Vega -- Vega (Alpha Lyrae) is the lead star in the constellation Lyra, reaching near directly overhead the mid-northern latitudes, during the summer. It's a "nearby star" at only 25 light years distant and together with Arcturus and Sirius, one of the brightest stars in the Sun's neighbourhood. Vega is a vertex of the Summer Triangle. Its spectral class is A0V (Sirius, an A1V, is slightly less powerful) and it's firmly in the main sequence, fusing hydrogen to helium in its core....
