A Name Tied to Scientific Breakthroughs
Nicole Oresme, born around 1320 in Normandy, served as Grand Master of the College of Navarre and later as Bishop of Lisieux. He conceived the idea of representing mathematical functions with rectangular coordinates, a technique typically attributed to Rene Descartes nearly three centuries later. Oresme also produced the first known proof for the divergence of the harmonic series and argued that the Earth might rotate on its axis, anticipating Copernicus.
