Gaspard-Gustave de Coriolis

Gaspard-Gustave de Coriolis was born in Paris on 21 May 1792, trained as a mathematician and mechanical engineer, and spent his career mapping the invisible mechanics of rotating systems. He was the first to call energy transfer through distance "work" — the term still used in physics — and he corrected Leibniz's vis viva by adding the factor of one-half, giving us the modern formula for kinetic energy. His deeper contribution came from analyzing forces that appear only to observers on spinning platforms: the supplementary accelerations now central to meteorology, oceanography, and ballistics.…
