A self-taught Scottish astronomer and lecturer sets out the Newtonian universe for readers who never studied mathematics. Ferguson describes the solar system, demonstrates the Copernican system and refutes the Ptolemaic, and works through the phases of the planets, eclipses, the tides and the seasons, illustrated with his own orrery and diagrams.
One of the most widely read popular astronomies of the eighteenth century, and a clear window on how Newton reached ordinary readers. Download the free EPUB.
