Robert Langer: I think that there is value in being disciplinary, doing something maybe narrow, but really going deep in it. But I also think that there is incredible value in what I might call convergence. That’s a term we use at MIT, where you can bring disciplines together and try to solve problems in new ways. Actually, I think what has happened at MIT and now a few other places is that they actually are trying to do that. We just have a new building that I’m in now called the Koch Institute, which is aimed primarily at cancer, and half the people in the building are outstanding biologists, and half the people in the building are outstanding engineers. I have seen that happen a few other places too, like at Harvard and the University of Chicago. I think that that idea of convergence really can enable scientists to get together in unusual ways, and therefore can create unusual things. So I think both things are of value.
