Who was the most prolific mathematical writer of all time?
Hint: He made large bounds forward in the study of modern analytic geometry?
Answer: Leonhard Euler. We owe Euler for the notation f (x) for a
function (1734), e for the base of natural logs (1727), I for the square
root of -1 (1777), p for pi, for summation (1755), the notation for finite
differences y and 2y and many others.
