Isaac Newton
was born in 1643 and died in 1727. He is considered to be one of the
greatest scientists of all time. He is credited as one of the inventors
of a branch of mathematics called calculus. He proposed the three laws
of motion which are the cornerstone of the study of mechanics in high school
physics classes. He derived the universal law of gravitation. He also studied
light and optics.
Newton was born on January 4, 1643, at Woolsthorpe, Lincolnshire, England.
He recieved a bachelor's degree from the University of Cambridge in 1665.
He received his master's degree in 1668.
In 1666, Newton developed a form of mathematics that is now known as calculus.
He did this by generalizing methods that were used to draw tangents to
curves and to calculate the area under a curve. Newton did not publish
his mathematical discovery (this was done by a German mathematician named
Leibniz), but is credited with its invention.
Newton believed that sunlight was a blend of many colors. He passes a beam
of sunlight through a glass prism, using refraction and reflection to split
the beam into its constituent colors.
Newton studied how forces effected the motion of objects, formulating his
three laws of motion. By applying these laws to the laws of orbital motion
developed by Kepler, Newton developed his universal law of gravitation.
In 1687, Newton published his theories in the book Philosophiae Naturalis
Principia Mathematica.
