At this year's Aspen Ideas Festival, we asked a group of academics within some of America's top universities to debate how STEM (science, technology, engineering, and math) could be benefitted by another letter. "I have no hesitation in saying we need to add the letter A," says Harvard University education professor Howard Gardner. "An education devoid of arts…is an empty, half-brain kind of education." Other panelists include Sebastian Thrun, Drew Faust, Erika Christakis, and Nicholas Dirks.

The Big Question is a series inspired by The Atlantic's back-page feature.
