| Description | Unpublished paper by Fraenkel regarding the mathematics behind the force of catapults, touching on the quadrature of irrational numbers, square roots, and attempting to disprove the theories of acceleration of falling bodies put forth by Isaac Newton and Galileo Galilei by way of levers. He describes his design for a machine made of levers that produce a combined force to move balls of varying densities. Fraenkel argues that Newton's theories are false because balls of different densities will not follow the same trajectory if the same amount of force is applied to them.
