For the model of the tennis ball, this means that, if the medium below the surface is denser than that above, the ball receives added speed at impact, as if it were struck again by the racket.

As Descartes emphasized, these operations do not make arithmetic of geometry, but rather make possible an algebra of geometrical line segments. Descartes sought, then, from the beginning of his research a symbolic algebra of pure quantity by which problems of any sort could be analyzed and classified in terms of the constructive techniques required for their most efficient solution.

Because of his general fame and philosophic study of the existence of God, some devout Catholics, thinking he would be canonized a saint, collected relics from his body as it was being transported to France for burial. His definition of the center of oscillation as the point at which the forces of the particles of the swinging body are balanced out led to quite meager results, and his attempt to explain centrifugal force as the tendency of a body to maintain its determination remained purely qualitative.

Division and the dikptrica operations are defined analogously. Clearly, then, it must descartds at Fand consideration of similar triangles shows that the angle of incidence ABH is equal to the angle of reflection HBF. The proof rests simply on the principle that every root must appear in one of the binomial factors of P x and that it requires n such factors to achieve x n as the highest power of x in that polynomial.

Although the Greek mathematicians had established the correspondence between addition and the geometrical operation of laying line lengths end to end in the same straight line, they had been unable to conceive of multiplication in any way other than that of constructing a rectangle out of multiplier and multiplicand, with the result that the product differed in kind from the elements multiplied.
