Calculus Made Easy
is a 1910 book on calculus
by Silvanus P. Thompson
, considered a classic and elegant introduction to the subject. The original text is public domain, but a 1998 update by Martin Gardner
is available which provides an introduction and notes to 'help' modern readers. He has also updated the terminology, and not only mathematical terminology. For instance, British terms like 'first form pupil' have been replaced by terms like 'high school student'. This is an example of cultural imperialism
. He has been criticized by John Baez and others for converting a succinct, focussed introduction into another lengthy calculus text stuffed with superfluous material. For instance, he spends many pages justifying Thompson's use of infinitesimals by citing Abraham Robinson's nonstandard analysis
thereby making the introduction much more lengthy.
