Conclusion

      The words above have credited both Gottfried Leibniz and Sir Isaac Newton with the invention of calculus and to say the least that is fair. Both legends solved the question within a couple years of each other and came up with their ideas in two different and unique ways. And I cannot think of any other invention that has stuck with the human race for over 300 years.  Calculus is used in every day in millions of different ways and only the future will tell how many more ways that humans will utilize this invention in the years to come.
