## Summary

Kathy Joseph, host of Kathy Loves Physics, joins Dave Jones and Chris Gammell to trace the intricate history of the Cathode Ray Tube (CRT). The conversation details the contributions of early physicists including Philo T. Farnsworth, who invented all-electric television, and Wilhelm Röntgen, who discovered X-rays using CRT technology. They discuss how experiments with vacuum tubes by Heinrich Hertz, J.J. Thomson, and others led to the discovery of the electron and the development of radar and television.
