Non-Newtonian Calculus

Mentioned the geometric slope in yesterday's tutorial, "What is Slope". There are many more slopes than we were taught. In the 1970's, my husband Michael and Robert Katz created systems of non-Newtonian calculus using different slopes. Thanks to the Internet, scientists are finding numerous applications, such as in economics, fractals, and imaging. A course on non-Newtonian calculus was conducted in the summer-term of 2012 by faculty of the Mathematical Image Analysis Group of Saarland University in Germany.
