Mathematical principles of natural philosophy: Book I: Method of first and last ratios -- Determination of centripetal forces -- Motion of bodies in eccentric conic sections -- Finding of elliptic, parabolic, and hyperbolic orbits from the focus given -- How the orbits are to be found when neither focus is given -- How the motions are to be found in given orbits -- Rectilinear ascent and descent of bodies -- Determination of orbits in which bodies will revolve, being acted upon by any sort of centripetal force -- Motion of bodies in movable orbits; and the motion of the apsides -- Motion of bodies in given surfaces; and the oscillating pendulous motion of bodies -- Motions of bodies tending to each other with centripetal forces -- Attractive forces of spherical bodies -- Attractive forces of bodies which are not spherical -- Motion of very small bodies when agitated by centripetal forces tending to the several parts of any very great body -- Book II: Motion of bodies (In resisting mediums): Motion of bodies that are resisted in the ratio of the velocity -- Motion of bodies that are resisted as the square of their velocities -- Motion of bodies that are resisted partly in the ratio of the velocities, and partly as the square of the same ratio -- Circular motion of bodies in resisting mediums -- Density and compression of fluids; hydrostatics -- Motion and resistance of pendulous bodies -- Motion of fluids and the resistance made to projected bodies -- Motion propagated through fluids -- Circular motion of fluids -- Book III: System of the world (In mathematical treatment): Rules of reasoning in philosophy -- Phenomena -- Propositions -- Motion of the moon's nodes -- General Scholium / Sir Isaac Newton -- Optics / Sir Isaac Newton -- Treatise on light / Christiaan Huygens.
