Everywhere around us are things that serve functions. We live in houses, sit on chairs, drive in cars. But these things don't only serve functions, they also come in particular forms, which may be emotionally or aesthetically pleasing as well as functional. The study of how form and function come together in things is what we call "Design." Today's guest, Ge Wang, is a computer scientist and electronic musician with a new book called Artful Design: Technology in Search of the Sublime. It's incredibly creative in both substance and style, featuring a unique photo-comic layout and many thoughtful ideas about the nature of design, both practical and idealistic. Ge Wang received his Ph.D. in computer science from Princeton University, and is currently Associate Professor at the Center for Computer Research in Music and Acoustics at Stanford University. He is the author of the ChucK programming language for musical applications, and co-founder of the mobile-app developer Smule. He has given a well-known TED talk where he demonstrates Ocarina, an app for turning an iPhone into a wind instrument.
