Transcript of A Timeline and personality profile of Sir Isaac Newton

25th December In Lincolnshire.
His father died before he was born.

His mother re-married when he was
2yrs old and moved in with her new
husband, Barnabas Smith alone,
leaving Isaac with his
grandmother. - free grammar school
- Trinity Collage, Cambridge

studied Physics

Bachelors (67)
Masters degree (68) Education: Isaac Died aged 85yrs old,

* His last decades were spent revising his major works, studying ancient history, and defending himself against critics.

* Newton was a man of simple tastes. He was angered by criticism or opposition, and harbored resentment; he was harsh towards enemies but generous to friends. Isaac Newton
died Sir
Newton A short history
of his life.... 1727 1643 7 years later,
Barnabas Smith died,

This led to the return of Isaac's mother,
along with three children whom she’d had. English physicist, mathematician, astronomer, natural philosopher, alchemist and theologian,

“Greatest scientist and mathematician that ever lived” Commemorations A 4m tall bronze statue of a naked Newton was commissioned in 1995 for the British Library.

It was created by Sir Eduardo Paolozzi, based on a 1795 engraving
by William Blake.
- While at Cambridge, he kept all his ideas and theories about motion (the three laws), gravity and diffraction of light and forces in a notebook. Sir Isaac Newton
* Isaac believed Leibniz had stolen the
discovery of the calculus away from him,
* Isaac, abusing his powerful position in
society, orchestrated a campaign to destroy
the reputation of leibniz
* His plan failed, and to this day, they share the
credits for calculus.

Isaac also had intense arguments with british physicist
Robert Hooke, who accused Newton of stealing from his work.

Even so, he still corresponded and exchanged ideas with Hooke. -He was regarded as a poor scholar at school, because he was not interested in his subjects, he spent nearly all his time on his own work and developing his ideas in his notebook. - His genius was recognized when his maths professor (Isaac Barrow) saw his notebook, which proved that he was far more in touch with modern day developments than most of his professors. In early life, Isaac had an introverted character and was very protective of his privacy Even when Isaac became rich and famous,
qualified and internationally recognized as
one of the worlds foremost thinkers, he was
still deeply insecure.

this is why it took Isaac years to publish his work,

He also suffered from:
* depression
* violent temper
* felt easily threatened In 1693, Isaac suffered a second nervous breakdown. After 5 nights of “not one wink”, Isaac temporarily lost all grip of reality and became convinced that his friends were conspiring against him. He recovered by the end of the year. 1704 Refraction
of light &
telescope 1705 *Newton's first piece of work as Lucasian Professor (a position now held by stephen Hawking) was on optics.

* Every scientist since Aristotle had believed that white light was a basic single entity. In 1670 he concluded that white light was not a simple entity because When he passed a thin beam of sunlight through a glass prism, a spectrum of colours is formed.

* He argued that white light is really a mixture of many different types of rays which are refracted at different angles. He therefore proposed and constructed a reflecting telescope “Newtonian telescope” (1668)
Isaac Newton's Inventions:

* The refracting telescope was used to produce clearly focused images.
* Newton replaced the mirrors of the refracting telescope with lenses.
* His new telescope, the reflecting telescope, was 1/12 the size of conventional refracting
telescopes and had
more powerful
powers. 1689,1701,1702: Newton was elected Member of Parliament
for the University of Cambridge. Over the decades theories have emerged to other possible causes of his breakdown, including:
* Chemical poisoning as a result of his alchemy
* Frustration with his researches
* The ending of a personal friendship with Fatio
De Duillier
* He was a repressed homosexual He believed all natural sciences could be explained through mathematics (equations).
This was groundbreaking and highly controversial
when introduced in 1670. "Newton's most important work"

-three laws of motion
-how elliptical orbits work
-how bodies in motion exert
force upon on another
-fluids and mechanics As old men,
they continued to
fight about their
contributions to calculus.
In scientific journals
and letters, they rallied
their supporters to
their respective
causes. The
Mathematica Begun at Cambridge in the mid-1660s, the Principia, was finally published in 1687.

scientists found the Principia very difficult to understand, and many scholars couldn't decipher it, including, for a time, Leibniz and Huygens­, two of Newton's great contemporaries 1661- 7 Isaac paid his way through school by acting as a servant to wealthy students and starting a small loan business 1665- 1667
Newton left Cambridge after an outbreak of the plague closed the university.
many believe he made his most important discoveries during one year in this period. the "year of miracles." Queen Anne knighted him because "his accomplishments laid the foundations for modern science
and revolutionized
the world"

* Newton even created a special name for
himself: the "Holy One"

* He attempted to produce philosophers'
stone: a substance that could turn metal
into gold, cure diseases and perform other
powerful effects.

* He didn't publish work on alchemy, He
thought he had made progress, and
wanted to keep his work to himself. It was believed Isaac's early experiences of loss and betrayal, led to his incapacity to trust and form close friendships with people. Who was

Personality: 1670 Isaac's feud with Robert Hooke *Newton was never good at
accepting criticism, the clashes
between Hooke, Leibiniz and others
spurred him to retreat from the
scientific community for much of
the 1670s.

* this, followed by the death of his
mother, caused Newton to isolate
himself, He published little and
devoted himself to religious and
