Marquis de Laplace

Kerre-Simon Laplace, Marquis de Laplace, 1749-1827. French natural scientist. 

Pierre Simon, Marquis de Laplace, bom Mar. 23, 1749, in Beaumount-en-Auge, Normandy, France, died Mar. 5,1827, in Paris. 

A sound wave is manifested as one kind of the atmospheric normal modes, known as the acoustic mode, and is caused by the compressibility of air. There are two more kinds One is called the gravity-inertia mode, which is caused by a combinations of the restitutive force of gravity against thermally stable atmospheric stratification and the Coriolis force due to the earth s rotation. The other kind is called the rotational or planetary mode, which is caused by the meridional variation of the Coriolis force. The importance of the latter kind of normal mode as a prototype of upper tropospheric large-scale disturbances was clarified by C. -G. Rossby and his collaborators a little over one decade prior to the dawn of the numerical prediction era (see Section I). In retrospect, the very natrrre of this discovery was hidden in complicated calcnlations for the normal modes of the global atmospheric model. The mathematical analysis was initiated by the French mathematician Marquis de Laplace (1749-1827), and the complete solntions became clear only with the aid of electronic compnters. It is remarkable that Rossby was able to capture the essence of this important type of wave motion, now referred to as the Rossby wave, from a simple hydrodynamic principle of the conservation of the absolute vorticity that is expressed by the sum of the vertical component of the relative vorticity and the planetary vorticify /. 

The Laplace equation is named for Pierre Simon, Marquis de Laplace, 1749-1827, a great French mathematician, physicist, and astronomer who also proposed that the solar system condensed from a rotating gas cloud. 

Nonetheless, the philosophical conundrum that emerges from classical mechanics is that the cosmos moves from a precisely determined past to a precisely predetermined future. Marquis de Laplace perhaps said it best We may regard the present state of the universe as the effect of its past and the cause of its future. An intellect which at any given moment knew all the forces that animate nature and the mutual...
