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.
Also in 1895, American inventor Major Woodville Latham (who had been working with Eugene Lauste and W.K.L. Dickson) developed an unpopular projector called an Eidoloscope (or Panoptikon projector). In New York on Frankfort Street, it was demonstrated by Latham for the NY press on April 21, 1895.
