Born on Christmas Day, 1642, Isaac Newton spent his early childhood in a small farm-house in the hamlet of Woolsthope, sixty miles northwest of Cambridge and one hundred miles from London. Newton's biological father died before he was born and his mother remarried two years later to the Reverend Barnabas Smith. Newton attended the King's School at Grantham at the age of twelve but was brought home by his mother at nearly the age of sixteen to manage the estate. Luckily for science, Newton showed little interest in farming. Newton's childhood acquaintances remember him building a model windmill, ingenious water-mill and many sun-dials (North 5-8).

Newton, as an unsuccessful farmer, entered Trinity College at the age of eighteen. He went as a subsizer (one who runs errands to pay for college). Here Newton studied Sanderson's Logic and Kepler's Optics along with a number of leading edge theories at the time. Newton was Lucasian Professor of Mathematics in Cambridge by 1663. In 1665 the Great Plague struck England and Newton retired to Woolsthorpe to lived in seclusion. Here Newton made some of the greatest discoveries of his career (North 9-12).

Newton took his first step beyond his mentors during the winter of 1664-5. During this time, Newton extended the use of Willis's infinite series to evaluate areas and developed what we now know as the binomial theorem. In Newton's studies he generalized Pascal's Binomial Theorem to fractional and negative powers (Westfall 42).

Newton also discovered the concept of decimal fractions, which could be used to evaluate Pi out to any given number of decimal places. Newton believed that quantities calculated by binomial expansion should be considered an infinite series. Adding the binomial ...

In this essay, the author

  • Explains that isaac newton spent his early childhood in a small farm-house in the hamlet of woolsthope, sixty miles northwest of cambridge and one hundred miles from london.
  • Explains that every object in a state of uniform motion tends to remain in that state unless an external force is applied to it. this law is essentially galileo's concept of inertia.
  • Explains that the relationship between an object's mass m, its acceleration a, and the applied force f is f = ma. acceleration and force are vectors.
  • Explains newton's simple law of universal gravitation, which states that every material object attracts other material objects with a force proportional to its mass and inverse to the square of the distance between them.
