FATHER OF
GRAVITY

In 1667, Newton returned to Cambridge, where he became a
fellow of Trinity College. Two years later he was appointed second Lucasian
professor of mathematics. It was Newton's reflecting telescope, made in 1668,
that finally brought him to the attention of the scientific community and in
1672 he was made a fellow of the Royal Society. From the mid-1660s, Newton
conducted a series of experiments on the composition of light, discovering that
white light is composed of the same system of colours that can be seen in a
rainbow and establishing the modern study of optics (or the behaviour of
light). In 1704, Newton published 'The Opticks' which dealt with light and
colour. He also studied and published works on history, theology and alchemy.
In 1687, with the support of his friend the astronomer
Edmond Halley, Newton published his single greatest work, the 'Philosophiae
Naturalis Principia Mathematica' ('Mathematical Principles of Natural
Philosophy'). This showed how a universal force, gravity, applied to all
objects in all parts of the universe.
In 1689, Newton was elected member of parliament for
Cambridge University (1689 - 1690 and 1701 - 1702). In 1696,Newton was
appointed warden of the Royal Mint, settling in London. He took his duties at
the Mint very seriously and campaigned against corruption and inefficiency
within the organisation. In 1703, he was elected president of the Royal
Society, an office he held until his death. He was knighted in 1705.
Newton was a difficult man, prone to depression and often
involved in bitter arguments with other scientists, but by the early 1700s he
was the dominant figure in British and European science. He died on 20 March
1727 and was buried in Westminster Abbey.

theory of gravity which he discover is the most important
theory for all tall buildings construction, aviation, and everything to do with
gravity will not happen if this theory of gravity was not found.
