From the beginning of time to particle accelerators and the future of energy, a survey of life (and death), the universe, and everything.

Want To Know When You’ll Die? 1100-1200 David Spiegelhalter, University of Cambridge

How long are you going to live, and what are you going to die of? What is more dangerous: horse riding or taking MDMA?  Can you predict the results of football matches? Professor Spiegelhalter guided us though surprising, amusing and thought-provoking ideas as we asked the question: What are the chances?

Hunting the Higgs 1200-1300 Jon Butterworth, University College London

How do you hunt for the most elusive particle in the universe and the key to our understanding of all matter? Higgs-hunter Jon Butterworth shed light on how and why the largest, most expensive and complex experiment in the history of science – the Large Hadron Collider at CERN – is doing just that.

The Origin of Symmetry 1300-1400 Ben Allanach, University of Cambridge

Everyone is hunting for the famed Higgs boson, the particle that physicists theorise must be there but have never detected. If it is found, how will it change the way we understand the world? Particle physicist Ben explained how scientists are theorising the universe, down to the smallest particle and right back to the very beginning.

How to Build A Miniature Sun 1400-1500 Kate Lancaster, Central Laser Facility, CCLRC Rutherford Appleton Laboratory

Lasers can be used in thousands of ways, from eye surgery to photography. Could they even be used to mimic the heart of our own sun to create a powerful but safe and renewable energy source – nuclear fusion? We discovered how lasers are burning new paths in our understanding of the universe and the future of our energy security with Kate Lancaster. Who, as it happens, has a wicked sense of humour. Or, as might be more apt, evil.

Spacecraft I Have Known and Loved 1500-1600 John Zarnecki, Open University

Celebrating 40 years of space travel and exploration with space scientist John as he took us on a survey of the satellites, rockets, landers, rovers and probes that forever changed our understanding of the universe and our place in it.
