2.  Isaac Newton (January 4,1643 to March 31,1727)
 A Physicist and Mathematician who developed the
principles of modern physics including the laws of
motion.
 One of the greatest minds of the 17th century Scientific
Revolution.
 In 1687, Most acclaimed work –Philosophiae Naturalis
Principia Mathematica called the single most
influential book on physics
 In 1705, he was knighted by Queen Anne of England,
making him Sir Isaac Newton.

3.  Newton made discoveries in optics , motion and
mathematics
 He theorized that white light was a composite of all
colors of a spectrum and the light was composed of
particles.
 He explain the laws of motion and the theory of
gravity
 Along with mathematician Goltfried Wilhelm von
Leibniz, Newton is credited for developing essential
theories of calculus

4.  Newtons first major public scientific achievment was
designing and constructing telescope in 1668
 He used his telescope to study optics and help prove
his theory of light and color
 The Royal society asked for a demonstration of his
reflecting telescope in 1671
 Newton published his notes on light,optics and color
in 1672
 A treatise of the Reflections ,Inflections and Colors of
Light.

6.  Newton returned home from Trinity college to pursue his
private study, as school was closed due to the Great plague.
Legend has it that, at this time, Newton experienced his
famous inspiration of gravity with the falling apple
.According to this common myth , Newton was sitting
under an apple tree when a fruit fell and hit him on the
head, inspiring him to suddenly come up with the theory
of gravity. While there is no evidence that the apple
actually hit Newton on the head, he did see an apple fall
from a tree, leading him to wonder why it fell straight down
and not at an angle. Consequently , he began exploring the
theories of motion and gravity.

8.  A Stationary body will stay stationary unless an
external forces is applied to it.
 Force is equal to mass times acceleration , and a
change in motion (ie;change in speed) is proportional
to the force applied.
 For every action , there is an equal and opposite
reaction.

9.  Newton was ready for a new direction in life. He no
longer found contentment in his position at
Cambridge and was becoming more invoved in other
issues.
 He helped lead the resistance to king James ll’s
attempts to reinstitute catholic teaching at cambridge
and in 1689 he was elected to represent Cambridge in
parliament
 While in London , Newton acquainted himself with a
broader group of intellectuals and became acquainted
with political philosopher John locke.

10. Though many of the scientists on the continent
continued to teach the mechanical world according to
Aristotle, a young generation of british scientists became
captivated with Newtons new view of the physical world
and recognized him as their leader

11.  CHANGING THE BRITISH CURRENCY FROM
SILVER TO GOLD STANDARD
 In 1696, Newton was able to attain the governmental
position he had long sought; warden of the Mint; after
acquiring this new title , he permanantly moved to
london and lived with the his niece, catherine barton.
 Newton approached the job in earnest , reforming the
currency and severly punishing counterfeiters.
 Newton moved the British currency the pound sterling
from the silver to gold standard

12.  In 1703 Newton was elected as president of the royal
society upon Robert Hooks death.
 Newton never seemed to understand the notion of
science as a cooperative venture and his ambition and
fierce defense of his own discoveries continued to lead
him from conflict to another with other scientist.
 Newton’s tenure at the society was tyrannical and
autocratic ; He was able to control the lives and careers
of younger scientist with absolute power.

13.  Towards the end of this life Newton had became one of
the most famous men in Europe . His scientific
discoveries were unchallenged.
 Despite his fame Newton’s life was far from perfect :
He never married or made many friends , and his later
years , a combination of pride , insecurity and side
trips on peculiar scientific inquires led even some of
his few friends to worry about his mental stability.

14.  Isaac Newton’s fame grew even more after his death ,
as many of his contemporaries proclaimed him the
greatest genius who ever lived.
 His discoveries had a large impact on western thought
, leading to comparisons to the likes of Plato , Aristotle
and Galileo.
 Although his discoveries were among many made
during the Scientific revolution ,Isaac newton’s
universal principles of gravity found no parallels in
sceince at the time.

15.  In Newton’s later life , when he asked for an
assessment of his achievements ,he replied;
“ I do not know what I may appear to
the world ; but to myself I seem to have been only like
a boy playing on the seashore , and diverting myself
now and then in finding a smoother pebble or prettier
shell than ordinary , while the great ocean of truth lay
all undiscoverd before me .”
