  1. Isaac Newton Rachael Jefferson

  2. Background Information • Born in 1642, at Woolsthorpe • Was a mathematician & a physicist • One of the most foremost scientific intellects of all time • Attended Cambridge University in 1661 • Elected a Fellow of Trinity College in 1667 • Lucasian Professor of Mathematics in 1669

  3. Accomplishments • Newton had MANY achievements in his lifetime • He built the first reflecting telescope in 1668 • He was also very involved with the concept of calculus • What stuck to him the most was the Laws of Motion & Law of Gravitation.

  4. Calculus • "The calculus, as developed by Newton, could be used and was used by him for the solving of a great variety of mechanical and hydrodynamic problems. It immediately became the mathematical instrument for all understanding of variables and motion, and hence of all mechanical engineering, and remained almost the exclusive one until well into the present century. In a very real sense it was as much an instrument of the new science as the telescope.“ - Bernal's Science in Historyop. cit., p. 484.

  5. Calculus (Cont.) • Differential calculus was created by Newton as early as 1666 • Wasn’t published till 1704 • There is controversy that Newton wasn’t the one to discover it • Some people believe it was a man by the name of Leibniz • With calculus, Newton was able to calculate the mass of the planets

  6. Laws of Motion • PhilosophiaeNaturalis Principia Mathematica(Mathematical Principles of Natural Philosophy) • This was the first and greatest work ever written in theoretical physics • "Every body continues in its state of rest, or of uniform motion in a right line, unless it is compelled to change that state by forces impressed upon it. ... The change of motion is proportional to the motive force impressed; and is made in the direction of the right line in which that force is impressed. ... [and] To every action there is always opposed an equal reaction: or, the mutual actions of two bodies upon each other are always equal, and directed to contrary parts.“

  7. Law of Gravitation • It is a force between any two bodies and is "directly proportional to the product of their masses and inversely proportional to the square of the distance between them. ... The measure of the force of gravitation on a given body on earth is the weight of that body." While certain of Newton's theories have not stood the tests applied in the 20th century, his law of universal gravitation has stood: "In the general theory of relativity, gravitation is explained geometrically: matter in its immediate neighborhood causes the curvature of the four-dimensional space-time continuum. -"The Scientists: Sir Isaac Newton (1642-1727)."
