Sir William Rowan Hamilton (1805-1865) was an Irish physicist, astronomer, and mathematician who made important contributions to mechanics, optics, and algebra. As a teenager, he mastered parts of Newton's Principia and studied Laplace's celestial mechanics treatise. When barely 22, Hamilton became a professor of astronomy at University of Dublin, however he was more interested in theoretical rather than practical astronomy.

Book Excerpt: Ptolemy succeeded in devising a scheme by which the apparent changes that take place in the heavens could, so far as he knew them, be explained by certain combinations of circular movement.
Great Astronomers By Robert S. Ball
This book looks at some of the great astronomers who have helped us expand our knowledge of the universe - from the observations of the ancient Greeks, to the photographs from the furthest space probe.
In his theory this huge error was associated with so much important truth, and the whole presented such a coherent scheme for the explanation of the heavenly movements, that the Ptolemaic theory was not seriously questioned until the great ...

Edmond[1] (or Edmund[2]) Halley, FRS (/ˈhæli/;[3][4] 8 November [O.S. 29 October] 1656 - 25 January 1742 [O.S. 14 January 1741]) was an English astronomer, geophysicist, mathematician, meteorologist, and physicist.
He compiled a catalogue of the principal fixed stars, which is of special value to astronomers, as being the earliest work of its kind which has been handed down.
