0:00:01.432,0:00:04.166 The most fascinating thing about science is the ideas, 0:00:04.166,0:00:07.495 it's the lifting of the human spirit. 0:00:15.124,0:00:17.541 We can justify what we do by the technological spinoffs, 0:00:17.541,0:00:24.086 and it's true General Relativity is esoteric, but you couldn't use your GPS machine without it. 0:00:24.086,0:00:27.581 Turns out the effects of General Relativity into satellites have to be incorporated, 0:00:27.581,0:00:32.301 if not, within a second you'd lose all knowledge of where you were on Earth with the GPS satellites, so 0:00:32.301,0:00:37.263 it's true that even the most esoteric ideas sometimes have technological spinoffs, 0:00:37.263,0:00:45.989 but I think it is misplaced to argue for doing fundamental research just because of these technological spinoffs. 0:00:46.712,0:00:50.487 The questions themselves have to be worth asking to be able to spend the money on it, 0:00:50.502,0:00:56.829 but having said that, it is absolutely true that our current standard of living 0:00:56.829,0:01:02.475 vitally depends on the curiosity-driven research that was done a generation or two before. 0:01:10.226,0:01:14.720 Discoveries come along that change everything when you didn't expect it, 0:01:14.720,0:01:17.493 and they come along because you didn't know what you were looking for, 0:01:17.493,0:01:21.259 and if we stop investing in fundamental research now, 0:01:21.259,0:01:25.673 it is true that our standard of living a generation from now, our children, 0:01:25.673,0:01:28.807 the legacy we leave our children, will be much poorer, 0:01:28.807,0:01:32.947 and in fact, it's one of the reasons why I argue that not just to live off selling natural resources, 0:01:32.947,0:01:36.029 but to think about the future, about doing fundamental research, 0:01:36.029,0:01:43.426 because the countries that are going to be able to compete in the XXI Century are those that are best at technology and ideas, and research. 0:01:43.426,0:01:48.691 So there is of course, not just this altruistic, idealistic notion of understanding the Universe, 0:01:48.691,0:01:54.586 if we want to address the challenges of the XXI Century, from energy and climate change, 0:01:54.586,0:01:57.283 we need to invest in fundamental research now. 0:02:00.036,0:02:01.786 I'm always worried about predictions about the future, 0:02:01.786,0:02:05.876 and people always ask me what's the next big thing, and I say if I knew I'd be doing it, 0:02:05.876,0:02:12.428 but what I'm convinced of, is that the most important things that we know 50 years from now, 0:02:12.428,0:02:14.834 will be things we have no idea about right now. 0:02:14.834,0:02:19.503 Nature continues to surprise us in ways we could never have expected. 0:02:19.503,0:02:22.863 Nature is much more imaginative than the human imagination is, 0:02:22.863,0:02:28.032 and in order to make progress, we keep having to question nature, explore it, 0:02:28.032,0:02:32.047 because it will yield those surprises that will change, not just our picture of ourselves, 0:02:32.047,0:02:34.693 but the way we carry out our lives. 0:02:40.431,0:02:42.300 As far as I know, people don't ask the question: 0:02:42.300,0:02:47.186 "What's the value of a Mozart symphony or a Picasso painting?" 0:02:47.186,0:02:49.999 Science is a cultural activity, 0:02:49.999,0:02:53.692 and it's produced some of the most amazing ideas that humans have ever thought about. 0:02:53.692,0:02:58.667 And the cultural value of science, of understanding where we are, where we come from, 0:02:58.667,0:03:04.584 is the same as art, music and literature. Great art, music and literature forces us to reasess our place in the Cosmos. 0:03:04.584,0:03:11.143 That's what science does at its best, and if we are so empoverished that we have to stop asking questions, 0:03:11.143,0:03:15.627 but where we come from and we're we going, it's indeed a sad time. 0:03:15.779,0:03:19.752 These are the most interesting questions the humans have ever asked, 0:03:19.782,0:03:26.031 and by comparison to the money we spend in many other things, that is, in my opinion, much more useless, 0:03:26.031,0:03:27.879 the investment is very small. 0:03:27.879,0:03:33.946 And so, if we are at the point where we have to say: "look, we can't stop asking these esoteric questions, 0:03:33.946,0:03:39.072 that change our picture of ourselves, then it's a sad time for humanity.
