Larry Gladney is Associate Professor of Physics and Dennis DeTurck is Professor of Mathematics, both at the University of Pennsylvania.
While the focus of these modules in Math and Physics is on conceptual learning, a great deal of the "utility" of introductory courses in calculus and physics is in developing problem-solving skills. Hence any textbook has many traditional examples of problems and many more exercises for the student than are presented within these modules.
A proper introduction to problem-solving starts by being reminded that the essence of scientific progress since Galileo is in experimenation and experimentation is founded on quantitative measurement.
As an example, consider the pictures below. They show two scenes of a girl walking a cow to pasture while simultaneously holding a kite on a windy day. Which of the two scenes are you more likely to see on a March day in Pennsylvania farmland?
