“I can calculate the motion of heavenly bodies, but not the madness of people.”

“The same law takes place in a system, consisting of many bodies, as in one single body, with regard to their persevering in their state of motion or of rest. For the progressive motion, whet...”

“Are not rays of light very small bodies emitted from shining substances?”

“It is reasonable that forces directed toward bodies depend on the nature and the quantity of matter of such bodies, as happens in the case of magnetic bodies.”

“We build too many walls and not enough bridges.”

“The moon gravitates towards the earth and by the force of gravity is continually drawn off from a rectilinear motion and retained in its orbit.”

“The motions of the comets are exceedingly regular, and they observe the same laws as the motions of the planets, but they differ from the motions of vortices in every particular and are ofte...”
