## At the age of 18, his mother attempted to make a farmer of him. ## At the age of 18, his mother attempted to make a farmer of him. ## He read the books of Copernicus, Kepler & Galileo. ## 1669, he became a professor of mathematics. ## (1670-1672) he taught Optics. ## 1687, he returned back to mechanics. ## 1704, back to calculus.
## Newton was also a member of the Parliament of England from 1689 to 1690 and in 1701, but according to some accounts his only comments were to complain about a cold draught in the chamber and request that the window be closed. ## Newton was also a member of the Parliament of England from 1689 to 1690 and in 1701, but according to some accounts his only comments were to complain about a cold draught in the chamber and request that the window be closed. ## In 1696, Newton moved to London to take up the post of warden of the Royal Mint. ## 1701, retired from Cambridge. ## Newton was made President of the Royal Society in 1703 and an associate of the French Academy of Sciences.
## n April 1705, Queen Anne knighted Newton during a royal visit to Trinity College, Cambridge. ## n April 1705, Queen Anne knighted Newton during a royal visit to Trinity College, Cambridge. ## 1717, Newton moved the Pound Sterling *de facto* from the silver standard to the gold standard. ## Newton died in his sleep in London on 31 March 1727. ## After his death, Newton's body was discovered to have had massive amounts of mercury in it. ## Mercury poisoning could explain Newton's eccentricity in late life.
## In 1704, developed infinitesimal calculus. (Leibniz 1684) ## In 1704, developed infinitesimal calculus. (Leibniz 1684) ## Newton is generally credited with: - the generalised binomial theorem, valid for any exponent.
- He discovered Newton's identities, Newton's method
- classified cubic plane curves (polynomials of degree three in two variables)
- made substantial contributions to the theory of finite differences
- was the first to use fractional indices
- He approximated partial sums of the harmonic series by logarithms
- was the first to use power series with confidence and to revert power series.
## he observed that color is the result of objects interacting with already-colored light rather than objects generating the color themselves. This is known as Newton's theory of color. ## he observed that color is the result of objects interacting with already-colored light rather than objects generating the color themselves.

## Isaac Newton showed that by shining white light through a glass prism it could be separated back into its different wavelengths. ## Isaac Newton showed that by shining white light through a glass prism it could be separated back into its different wavelengths. ## and that a __lens__ and a second prism could recompose the multicolored spectrum into white light. ## Newton’s color disk
## In 1668, he was able to produce the first *reflecting telescope.* *It is known as Newtonian Telescope.*
*It has many advantages compared to the refracting telescope.*
## In 1687, returned back to work on Mechanics. ## In 1687, returned back to work on Mechanics. ## What makes an apple falls down, is responsible for keeping the moon in orbit. ## The moon is always falling toward Earth. ## It constantly, misses the Earth.
## More than 200 years later, his ideas were put in action.
**The Law of Inertia:** **The Law of Inertia:**
## In the absence of external forces, when viewed from an inertial reference frame, an object at rest remains at rest and an object in motion continues in motion with a constant velocity (that is, with a constant speed in a straight line).
## the acceleration of an object is directly proportional to the net force acting on it and inversely proportional to its mass. ## the acceleration of an object is directly proportional to the net force acting on it and inversely proportional to its mass.
## If two objects interact, the force F12 exerted by object 1 on object 2 is equal in magnitude and opposite in direction to the force F21 exerted by object 2 on object 1. ## If two objects interact, the force F12 exerted by object 1 on object 2 is equal in magnitude and opposite in direction to the force F21 exerted by object 2 on object 1.
