 The key thing about the LIYS is it mixes science, social elements and getting people involved in demonstrating their own research to their projects. I think that's key but it uses science as a catalyst to bring people together so they can communicate their ideas and really understand the importance of science in the broad endeavors of the world. Science for all religion for all culture for all a color and it is the university doesn't look at where you come from. I think there are real friendships that form in my own experience you know I'm still in touch with people that I met here in London at the science forum and that's nearly 30 years later and there are names that I read in the headlines and read the newspapers that I remember from that year so I have to believe it's all the same people. The ways that I would say the ways a science can improve communities is to listen and to learn more from what has happened in the past to be more reflective. The world can change and the world can change to the better I think the world has changed for the better over the last 50 70 years. That change comes about because people don't accept today and they want to make a better world. That drive comes from young people it doesn't come from people my age don't accept the world for what it is except for the world for what you would like it to be. My advice for participants is to just say yes to stuff a lot of the weird and wonderful opportunities that have come my way over the years have been just because I said yes to opportunities. Find a problem that really does excite you an itch you want to scratch and just then think what would I need to address that what are the disciplines I need don't necessarily think that the problem will be solved using one particular approach or another be open to the possibility of moving fields as well from chemistry to biology biology to physics when I was a young girl I was really excited by science but there were no opportunities like this forum if there had been I would have been there like a shot. They should harness every opportunity that they get every interaction that they make networks are what support people and networks are what build leaders. We talk about going to these alien planets to go to live probably there is no planet B this is the one we live on and this is the one which young scientists I hope can help us fix because it's pretty broken at the moment and go on to a better future where maybe we can actually go to other planets.
