Newton actually discovered calculus between 1665 and 1667 after his university closed due to an outbreak of the Plague. Newton was only 22 at the time, and he preferred not to publish his discoveries. Meanwhile, in Germany, Leibniz discovered Calculus independently and he was very open with his findings. This led to a bitter dispute between the two mathematicians later known as the Great Sulk. Today it is well known that both men discovered calculus independantly of the other, Leibniz about 8 years after Newton.
While many people believe that calculus is supposed to be a hard math course, most don't have any idea of what it is about. The good news is that if you remember your algebra and are reasonably good at it then calculus is not nearly as difficult as its reputation supposes. This article attempts to explain just what calculus is about--where it came from and why it is important.
