 I've been plied with beer to give talks, but I think the real thing is it is a two-way stream. Some people view it as, okay, yeah, I'm going to a school and I'm teaching people about science. It's not like that. You learn something from the experience, whether it be improving your public speaking, or to be honest, looking at your research from a different perspective, because you can deliver what you think is the perfect logical process of any point of research that you want to explain. But as soon as that's reflected back at you by an audience, no matter what age, you start to see it from different angles and that is what really changes maybe and maybe makes you think about your research in different ways. So it's a two-way process and it's fun. It really is fun, as I say. You get to do things you wouldn't otherwise do, go places you wouldn't otherwise go, and meet people and work with people that you certainly wouldn't otherwise work with. Well, the key thing is that neutrinos are slippery customers and they're very difficult to detect. The reason for this is we've got 12 basic building blocks of nature. Nine of them have an electric charge and so they play nicely with our particle detectors because the only way we can see these particles is through the electromagnetic force, so they need to have an electric charge if we're able to see them. Neutrinos don't and they interact only via what we call the weak nuclear force, which is responsible for things like nuclear decay and the processes that are going on in the sun to produce light. The difficulty about that is that means that the neutrinos really rarely interact with normal matter around us because they see most of the matter around us as pretty much empty space, 99.999% empty space. So there's a very rare chance that a neutrino will actually even notice that there's something around it, let alone interact. This is interesting because neutrinos are still probably the least understood of these 12 building blocks. We're not entirely sure what secrets they might hold because we're still pinning down their characteristics. We're getting to the point now, exciting, where we're getting these final characteristics measured and we're pinning them down and we're getting to the point now where they're going to start unlocking some of their secrets. We don't know what secrets they may hold. We have ideas, of course. We hope that they might be able to address the fact that there is more matter in exactly everything around us is made from matter than antimatter because from a pure energy big bang we should really expect there's equal amounts of matter and antimatter but that's not what we find. We live in a purely matter dominated universe. So what happened to the antimatter or rather why does nature prefer matter over antimatter? And we believe that that answer might be locked in the neutrino as well as other much more fundamental key things that might actually allow us to understand the very fabric of nature itself.
