Altogether it was an inspiring day, led by an inspiring individual. And it got to the heart of what we are trying to do with this month's cover story. STEM education—short for science, technology, engineering, and math—is a topic near and dear to Popular Science. We believe that science and technology are the engines that drive civilization forward. The more people who are moved to take up careers in those fields, the better off we, as a society and a planet, will be.
