Emerson (1701-1782), who is well known for his mathematical works, gives a historical overview of “the earliest science.” This is a comprehensive account of the systems of the world, the motion of the planets, and their periods. Emerson contemplates solving some of the principal astronomical problems by spherical trigonometry and by globes. He discusses the theory of the moon and satellites and the calculation of eclipses, as well as the contributions of Tycho Brahe, Kepler, Galileo, Halley, and Newton.
