  Albert wrote a treatise on proportions dedicated to the analysis of motion, highly influenced by the treatise De proportionibus velocitatum in motibus of Thomas Bradwardine. He explains in a synthetic way the elements of the theory of proportions, applying this theory to different motions (local motion, alteration, augmentation, and diminution). Motion is to be studied “from the point of view of the cause” and “from the point of view of the effect”. Like Oresme, Albert adopts the idea that motion varies according to a geometrical progression when the relation of motive force to resistance varies arithmetically. His treatise is less innovative than Oresme’s, but it is a clear exposition that was very widely read.
