Science and engineering have dominated world events and world culture for at least 150 years. The blind and near blind have been made to see. The deaf and near deaf have been made to hear. The ill have been made well. The weak have been made strong. Radio, television and the internet have made the world seem smaller. And some of us have left the planet. Computers have played an essential role in all of these developments; they are now ubiquitous. These miraculous events happened by design— not by accident. Individuals and teams set out to accomplish goals. They systematically studied and analyzed the natural world around.
