Thomas Edison was an American inventor and businessman who developed many early electric power technologies including a commercially practical electric light bulb. He was born in 1847 in Ohio and grew up in Michigan, the seventh and last child of his parents. In 1878, he formed the Edison Electric Light Company in New York City to commercialize his research into electric lighting. On December 31, 1879, he gave the first public demonstration of his incandescent light bulb. Edison died in 1931 at his home in New Jersey.

2. • Thomas Alva Edison :Thomas Edison
was born in Milan, Ohio, and grew up in
Port Huron, Michigan. He was the
seventh and last child of Samuel
Ogden Edison, Jr. (1804–96, born in
Marshalltown, Nova Scotia, Canada)
and Nancy Matthews Elliott (1810–
1871, born in Chenango County, New
York). His father had to escape from
Canada because he took part in the
unsuccessful Mackenzie Rebellion of
1837. Edison considered himself to be
of Dutch ancestry.

3. • In 1878, Edison formed the Edison
Electric Light Company in New York
City with several financiers, and
the members of the Vanderbilt
family. Edison made the first public
demonstration of his incandescent
light bulb on December 31, 1879, in
Menlo Park. It was during this time
that he said: "We will make
electricity so cheap that only the
rich will burn candles."

4. Edison became the owner of his
Milan, Ohio, birthplace in 1906. On his
last visit, in 1923, he was shocked to
find his old home still lit by lamps
and candles.
Thomas Edison died of complications
of diabetes on October 18, 1931, in his
home, "Glenmont" in Llewellyn Park
in West Orange, New Jersey, which he
had purchased in 1886 as a wedding
gift for Mina. He is buried behind the
home.[

6. • Sir Isaac Newton (25 December 1642 –
20 March 1727) was an English
physicist, mathematician,
astronomer, natural philosopher,
alchemist, and theologian, who has
been "considered by many to be the
greatest and most influential
scientist who ever lived."

7. • From the age of about twelve until he was seventeen, Newton
was educated at The King's School, at Grantham. In June 1661, he
was admitted to Trinity College, Cambridge as a sizar – a sort of
work-study role. At that time, the college's teachings were based
on those of Aristotle, but Newton preferred to read the more
advanced ideas of modern philosophers, such as Descartes, and
of astronomers such as Copernicus, Galileo, and Kepler. In 1665,
he discovered the generalized binomial theorem and began to
develop a mathematical theory that later became infinitesimal
calculus. Soon after Newton had obtained his degree in August
1665, the university temporarily closed as a precaution against
the Great Plague.

8. The Calculus Priority Dispute
Newton had the essence of the methods of
fluxions by 1666. The first to become
known, privately, to other mathematicians, in
1668, was his method of integration by infinite
series. In Paris in 1675 Gottfried Wilhelm
Leibniz independently evolved the first ideas
of his differential calculus, outlined to
Newton in 1677. Newton had already described
some of his mathematical discoveries to
Leibniz, not including his method of fluxions. In
1684 Leibniz published his first paper on
calculus; a small group of mathematicians
took up his ideas. From 1670 to 1672, Newton
lectured on optics. He also showed that the
coloured light does not change its properties
by separating out a coloured beam and shining
it on various objects

9. Mechanics and gravitation
• In 1679, Newton returned to his work on (celestial)
mechanics, i.e., gravitation and its effect on the orbits of
planets, with reference to Kepler's laws of planetary
motion. This followed stimulation by a brief exchange of
letters in 1679–80 with Hooke, who had been appointed to
manage the Royal Society's correspondence, and who
opened a correspondence intended to elicit contributions
from Newton to Royal Society transactions. Newton's
reawakening interest in astronomical matters received
further stimulus by the appearance of a comet in the
winter of 1680–1681, on which he corresponded with John
Flamsteed. After the exchanges with Hooke, Newton
worked out a proof that the elliptical form of planetary
orbits would result from a centripetal force inversely
proportional to the square of the radius vector . Newton
communicated his results to Edmond Halley and to the
Royal Society in De motu corporum in gyrum, a tract
written on about 9 sheets which was copied into the Royal
Society's Register Book in December 1684.This tract
contained the nucleus that Newton developed and
expanded to form the Principia.
