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.
Santorio invented several instruments, a wind gauge, a water current meter, the pulsilogium, and a thermoscope, a precursor to the thermometer. Santorio was the first to apply a numerical scale to his thermoscope, which later evolved into the thermometer.
