 So it's an absolute huge honour to be able to speak to 500 students, I believe it is, from 70 different countries to all come together and to interact, and the wonderful thing is just how interdisciplinary it is from wide range of different disciplines. We need a lot more of that. We need a heck of a lot more of that in science because that's where the real innovation comes from. It's when people from different disciplines communicate with each other. So I'm a physicist, but some of the most important discussions I've had in terms of driving my research and the group's research forward has been with artists and musicians and with biologists, yeah, even biologists, and right across the board, and that's what I love about this, it's not just the international character but the interdisciplinary character. And those students, when they talk to each other, they get their sort of intellectual world broadened, and that's wonderful.
