Calculus really is "the language of science." Students who want to study technical careers from physics to finance need to speak this language. Calculus: The Language of Change shows them how.
The text table of contents is quite different from the contents of the popular text format used for over 50 years in the US. Modern computing with Mathematica or Maple makes it possible for beginning students to solve real problems while they are learning the basics. 
Projects for Calculus: The Language of Change: aimed at answering the student's question: "What good is it?"
The book of projects is very different from the shortened examples from traditional books. Modern computing makes the real openended projects possible.
