Newton was an English physicist and mathematician born in 1643 who made seminal contributions to the fields of mechanics, optics, and mathematics. He formulated Newton's laws of motion, invented calculus, and discovered that white light consists of the visible spectrum of colors. Some of his major works include Mathematical Principles of Natural Philosophy, which described universal gravitation and the three laws of motion, and Opticks, where he established the corpuscular theory of light. Newton helped revolutionize scientific thought and establish the foundations of modern physics.

3. Early Life
 Newton was born on January 4, 1643 (December 25,
1642)
 From Woolsthrope-by-Colsterworth, Lincolnshire,
England
 Was born prematurely
 He was born 3 months after his father’s death
 He was raised by his grandparents
 Came from a family of farmers
 He was a mathematician, astronomer, physicist, &
philosopher

4. Education
 From the age of 12- 17, Newton studied at The King’s
School, Grantham
 At the original school’s building you can see his signature
in the library window sill
 He was removed from school , moved back with his mother,
she wanted him to become a farmer
 He hated farming
 Henry Stokes, master of The King’s School persuaded his
mom to let Newton further his education
 Newton became the top ranked student
 He saw the developments of his theories of calculus, optics
and the law of gravitation.

5. Calculus
 Newton started developing calculus in1666, but never got around to publish in that time.
 He got in a dispute with Gottfried Leibniz, (who had also been working his methods of
calculus.
 Newton & Leibniz share the credit of developing the integral calculus.
 He demonstrated the binomial theorem, Newton’s method of approximating the roots of
constant.

6. Optics
 From 1670 – 1672 he lectured in optics
 Investigated the refraction of light
 Discovered that light had a spectrum of colors
 He build the first refracting telescope, instead of
using lenses, he used a curved mirror
 He invented the Newtonian telescope

7. NEWTON’S
CORPUSCULAR THEORY
OF LIGHT
 Proposed by Isaac Newton in 1600’s
 Light is made of particles called “corpuscles”
 Could explain rectilinear propagation, ray model of light,
reflection, refraction ; all observed in 17th century .
 Predicted light would travel faster in water than in air
