Newton, Sir Isaac (1642-1727)
Mathematician and physicist, one of the foremost scientific intellects of all time. Born at Woolsthorpe, near Grantham in Lincolnshire, where he attended school, he entered Cambridge University in 1661; he was elected a Fellow of Trinity College in 1667, and Lucasian Professor of Mathematics in 1669. He remained at the university, lecturing in most years, until 1696. Of these Cambridge years, in which Newton was at the height of his creative power, he singled out 1665-1666 (spent largely in Lincolnshire because of plague in Cambridge) as “the prime of my age for invention”. During two to three years of intense mental effort he prepared Philosophiae Naturalis Principia Mathematica (Mathematical Principles of Natural Philosophy) commonly known as the Principia, although this was not published until 1687.
As a firm opponent of the attempt
by King James II to make the universities into Catholic institutions, Newton was
elected Member of Parliament for the University of Cambridge to the Convention
Parliament of 1689, and sat again in 1701-1702. Meanwhile, in 1696 he had moved
to London as Warden of the Royal Mint. He became Master of the Mint in 1699, an
office he retained to his death. He was elected a Fellow of the Royal Society of
London in 1671, and in 1703 he became President, being annually re-elected for
the rest of his life. His major work, Opticks, appeared the next year; he
was knighted in Cambridge in 1705.
As Newtonian science became increasingly accepted on the
Continent, and
especially after a general peace was restored in 1714, following the War of the
Spanish Succession, Newton became the most highly esteemed natural philosopher
in Europe. His last decades were passed in revising his major works, polishing
his studies of ancient history, and defending himself against critics, as well
as carrying out his official duties. Newton was modest, diffident, and a man of
simple tastes. He was angered by criticism or opposition, and harboured
resentment; he was harsh towards enemies but generous to friends. In government,
and at the Royal Society, he proved an able administrator. He never married and
lived modestly, but was buried with great pomp in Westminster Abbey.
Newton has been regarded for
almost 300 years as the founding examplar of modern physical science, his
achievements in experimental investigation being as innovative as those in
mathematical research. With equal, if not greater, energy and originality he
also plunged into chemistry, the early history of Western civilization, and
theology.
