ELI5: Explain Like I'm 5

Carl Reichenbach

Carl Reichenbach was a scientist who lived a long time ago. He studied things that are too small to see with our eyes, called "energy fields". He believed that some people could see these energy fields and he called them "sensitives".

Reichenbach also studied some special rocks called "crystals". He believed that these crystals had special powers that could help heal people and make them feel better. He even created a special science called "Odic force" to study how these crystals could help people.

While some people believed in Reichenbach's studies, many other scientists did not. They thought his ideas were not based on real science and he was just making things up. Nowadays, scientists still study energy fields and crystals, but they use more advanced methods to understand them.
