Pierre Simon Laplace : French Mathematician, physicist, and Astronomer

  • Pierre-Simon, marquis de Laplace was a French Scholar and Mathematician who was born in Beaumont-en-Auge, Normandy, the Kingdom of France on 23 March 1749. Apart from Mathematics and Statistics, He has contributed to philosophy, engineering, physics, and astronomy. 
  • In 1806, Laplace became a member of the Empire.
  • Laplace derived Laplace’s equation and explored the Laplace transform which comes in many branches of scientific physics and mathematics.
  • The Laplacian differential operator, which is extensively used in mathematics, is found by him and so it is named after him. He improved the nebular hypothesis and the theories and concepts of the origin of the Solar System. He was one of the first scientists to propose the notion of gravitational collapse and the existence of black holes.
  • People call him as Newton of France or French Newton.
  •  In 1771, Laplace’s published many works of Physics and Mathematics. He started working on finite differences and differential equations. He was also researching on the concepts of probability and statistics. 
  • In 1773, he wrote two papers, which got published in the later years. The first, Mémoire sur la probabilité des causes par les événements was ultimately published in 1774 and the second paper, published in 1776.
  • In 1784–1787 he published some memoirs. Notable among these are Théorie du Mouvement et de la figure elliptique des planètes in which was printed in 1784, and in the third volume of the Mécanique céleste.
  • In these books, he has mentioned how spheroid gets attracted to on a particle outside it. This gave rise to a new concept called  Laplace’s coefficients or the analysis of spherical harmonics. 
  • The common concepts that we use in celestial mechanics in today’s world called gravitational potential were raised because of him.
  • On 5 March 1827, Laplace died in Paris. His physician, François Magendie, removed his brain after his death and kept it safe for many years, and displayed his brain in a roving anatomical museum in Britain. As compared to the average brain of humans, his brain is much smaller. He was buried at Père Lachaise.
