Did You Know?

Aerodynamics began as a science around the time of the Wright brothers' first manned flights. Since then, it's become important to the building not only of aircraft and automobiles but also of rockets and missiles, trains, ships, and even such structures as bridges and tall buildings, which often have to withstand strong winds. An aerodynamic vehicle is one whose design helps it achieve the greatest speed and most efficient use of fuel. But although we might casually call any sleek car design aerodynamic, true aerodynamics is practiced not by artistic product designers but instead by highly trained scientists, and many people's lives depend on their work.
