Lisa Falk's presentation about the Neutrino, one of the fundamental particles which make up the universe - Also, currently, one of the least understood. Subatomic particles produced by the decay of radioactive elements. They're special for many reasons - They have no charge, are incredibly light, travel at near light speed and travel through most other matter. Following the introduction to what they are, she detailed the challenges of detecting them (she's been directly involved in these experiments, including time at CERN), and the vast equipment that's used. Finally she talked about the DUNE project, the next stage in Neutrino detection. Presented to Cafe Scientifique, Isle of Wight, 11th May 2015.
