8831Profit from Science: Solving Business Problems Using Data, Math, and the Scientific Process
http://library.wolfram.com/infocenter/Books/9241/
Contributed by: George Danner. Most of us learn about the scientific method when we are young and make ample use of it throughout our schooling. Yet once we get in the world of work, somehow this process is left behind in favor of experience, rigid adherence to rules, gut feeling, and/or lightning fast decision making. Profit From Science seeks to subvert this trend. Author George Danner presents ...BooksTue, 06 Oct 2015 11:13:57 -0600Mathematica Graphics Example Book for Beginners
