Neuronal signaling. To support the general function of the nervous system, neurons have evolved unique capabilities for intracellular signaling (communication within the cell) and intercellular signaling (communication between cells).
Because of this, gyroscopes are useful for measuring or maintaining orientation. Invention History. The gyroscope was invented in 1852 by the French experimental physicist Leon Foucault (1819-1868) as part of a two-pronged investigation of the rotation of the earth.
Gyroscopic compasses are aligned to the true North Pole and have a needle that spins in relation to the rotation of the earth. They are often used by ships or aircraft so that any local magnetic equipment doesn't interfere with navigation. Thus, they can quickly adjust to movements. This type of compass is usually set to point at true north, based on the direction of a magnetic compass, and then periodically checked with a magnetic compass to assure accuracy. The earliest compasses were most likely invented by the Chinese in around 1050 BCE. They were created first for the purposes of spiritual life or developing a feng shui environment and then later used for navigation.
