[BUG] great calculus book

[Tevian Dray]

A wonderful book on first-year calculus is "Calculus Made Easy" by
Silvanus P. Thompson, first issued in 1910 (and never out of print
since!).  The most recent edition I am aware of is from 1998, with
Martin Gardner as a coauthor; I bought a copy from Amazon for $15.

This book uses an intuitive notion of differentials to do both
derivatives and integrals in single-variable calculus.  (You may
therefore want to start right in with the original text, rather than
Gardner's preliminary chapters, especially on first reading.)

>From the title page:
	What one fool can do, another can.

>From a review:
	(This book) teaches a system of approximation that makes
	quite clear the central idea of calculus -- the idea that is
	extraordinarily difficult to comprehend using the
	mathematician's elegant method of limits.

>From the first page:
	Those dreadful symbols are:
	(1) d which merely means "a little bit of".
	...
	(2) "integral sign", which is merely a long S, and may be
	called (if you like) "the sum of".

Enjoy!
