Historical Collection; spine call no. over-painted. Generally very good. The primary scientific work of William Gilbert â" much inspired by earlier works of Robert Norman â" was De Magnete, Magneticisque Corporibus, et de Magno Magnete Tellure (On the Magnet and Magnetic Bodies, and on the Great Magnet the Earth) published in 1600. In this work, Gilbert described many of his experiments with his model Earth called the terrella. From these experiments, he concluded that the Earth was itself magnetic and that this was the reason compasses point north (previously, some believed that it was the pole star (Polaris) or a large magnetic island on the north pole that attracted the compass). He was the first to argue that the centre of the Earth was iron, and he considered an important and related property of magnets, being that they can be cut, each forming a new magnet with north and south poles. â" Wikip. / Duane Roller, was McCasland Professor and David Ross Boyd Professor of the History of Science, Curator of the History of Science Collections, of the University of Oklahoma. This work was the basis of his 1954 dissertation.
