A sophomore level introduction to linear algebra which provides a solid foundation in the mathematics and at the same time teaches the student how to use linear algebra. Real applications are introduced. These include an analysis of traffic flow in Jacksonville, predicting weather patterns in Tel Aviv, determining the role of Moscow on the trade routes of Russia, and understanding the behavior of time on a space voyage to Alpha Centauri. Other applications come from such fields as archaeology, demography, sociology, electrical engineering, physics and fractal geometry.
