In this podcast extra episode, Jeni teams up with our good friend Dr Chris North from the Pythagoras Trousers podcast to speak to Caltech's Linde Professor of Physics and Nobel Laureate Barry Barish. In this interview we discuss:

• The early days of experimental particle physics
• Building the advances in technologies for today's experiments and detectors
• The fear of failure creating resistance to building LIGO
• Wanting to collect direct detections of signals from the Big Bang
• The first detection of gravitational waves
• The pomp, circumstance & minutiae of a Nobel Prize award
• Post Nobel science influence
• Advice for people wanting a career in STEM
