Electron Discovery

In this video, we begin with Geissler's gas discharge experiments, which laid the groundwork for understanding electrical conductivity in gases. Next, we explore Philip Lenard's work, demonstrating that cathode rays could penetrate thin metal foils, suggesting they were particles. Following this, we discuss Crookes' experiments with cathode rays, showing their deflection by magnetic fields and hinting at their particle nature. Finally, we go into J.J. Thomson's experiments, where he measured the charge-to-mass ratio of these particles, confirming they were much smaller than atoms. Stay tuned for the details on this fascinating journey leading to the discovery of the electron.

"Electricity and Matter" by J. J. Thomson is a great read.

Thomson was also Ernest Rutherford's mentor, another great discovery.
