Two professors who study the science of complexity - Brenda Zimmerman of York University and Sholom Glouberman of the University of Toronto have proposed a distinction among three different kinds of problems in the world. a. Simple Problems e.g. baking a cake from a mix. There is a recipe. Sometimes there are few basic techniques to learn.
