Where do world-changing ideas come from? The School of Design at Carnegie Mellon shines a spotlight on design thinking with their Spring lecture series, Design the Future. As Terry Irwin, head of the School of Design, explains, "hit-or-miss inspirations aside, one of the steadiest sources of innovation today is the mindset best described as 'design thinking.'"

Tomorrow night, the second lecture in the series will be presented by Cheryl Heller, communication designer. Her presentation will be about connecting language and design to the project of social innovation.
