This is first a great story introducing the reader to the calculus as the woven, dare I say the integrated product of the brilliant men and women who, through tremendous imagination, creativity, and diligence, fashioned the jewel of mathematics set before us today.  For those who are not familiar with it, this offers an inviting entrance to a journey that can pivot and enhance understanding of, well, everything.  For those who's mind has already been stretched beyond its elastic modulus by our friend, the calculus, this will be a great review, might fill in some history, and should provide fresh inspiration for further pursuit of God's language!
