The eponymous German physicist is composed of two names: Ohm (3 letters) and Gauss (5 letters). Georg Ohm was a German physicist who formulated Ohm's law, which states that the current through a conductor between two points is directly proportional to the voltage across the two points. Carl Friedrich Gauss was a German mathematician, astronomer, and physicist who made significant contributions to many fields, including number theory, algebra, statistics, analysis, differential geometry, geodesy, geophysics, electrostatics, astronomy, and optics.
