How AI Predicted Fusion Ignition Before It Happened

June 21, 2023- 
At 1:03 a.m. on Dec. 5, 2022, 192 laser beams at the National Ignition Facility focused 2.05 megajoules of energy onto a peppercorn-sized capsule of frozen hydrogen fuel. In this talk, Humbird and Peterson discussed the breakthrough experiment, nuclear fusion, and how we used machine learning to call the shot heard around the world.
