Complex variables are not simply a mathematical curiosity or academic exercise. They are marvelously useful tools that can open up new solutions to a wide variety of practical problems. After all, mathematics is far more like a language of logic than a collection of facts and figures. Complex variables allow us to handle many two-dimensional problems as if they were merely one-dimensional. They also help us to see that problems in differing fields of applied science are similar and may even unfold with the same solution techniques. Lessons learned and solutions found in one field leading to applications in another is like mathematical recycling! Join me on a tour of this fascinating field of applied mathematics.
