This book demonstrates how science and math go hand in hand. Math helps chemists and biologists discover cures for diseases, and it allows physicists to predict a car or rocket's movements. More accessible to students today is how math helps scientists design the computers and cell phones that are so commonplace. Readers will learn about this and more while answering the question, "What good is math in the real world?" Readers will learn how to apply mathematical principles to their daily lives and build a career from the parts that are most interesting to them.
