By transforming the system of measurement, Gauss had been able to greatly simplify the calculation of planetary orbits.

By calibration and calculation, these measured quantities can lead to a measurement of humidity.

By the end of the 1930s the topology was well established and had been described by various authors including Offner ( 1937 ), Schmitt ( 1937 ) and Toennies ( 1938 ) and It was particularly used for detection and measurement of physiological impulses.
