Currently Playing: Discovery of the anomalous Zeeman effect

Buy me a coffee and support the channel: https://ko-fi.com/jkzero In this video, I present the story of the anomalous Zeeman effect, its discovery by Thomas Preston, and its confirmation by others. This is a follow-up of my previous video about the discovery and explanation of the normal Zeeman effect.
