On The Figure of The Earth
During the years 1784–1787 he published some memoirs of exceptional power. Prominent among these is one read in 1783, reprinted as Part II of Théorie du Mouvement et de la figure elliptique des planètes in 1784, and in the third volume of the Mécanique céleste. In this work, Laplace completely determined the attraction of a spheroid on a particle outside it. This is memorable for the introduction into analysis of spherical harmonics or Laplace's coefficients, and also for the development of the use of what we would now call the gravitational potential in celestial mechanics.

Famous quotes containing the words figure and/or earth:
“The eye is the first circle; the horizon which it forms is the second; and throughout nature this primary figure is repeated without end. It is the highest emblem in the cipher of the world.”
—Ralph Waldo Emerson (1803–1882)
“It is true, there are the innocent pleasures of country life, and it is sometimes pleasant to make the earth yield her increase, and gather the fruits in their season; but the heroic spirit will not fail to dream of remoter retirements and more rugged paths. It will have its garden-plots and its parterres elsewhere than on the earth, and gather nuts and berries by the way for its subsistence, or orchard fruits with such heedlessness as berries.”
—Henry David Thoreau (1817–1862)
