Johann Karl Friedrich Zöllner

Johann Karl Friedrich Zöllner was a German astrophysicist and researcher in the 19th century, known for studying light, perception, and phenomena like optical illusions. He explored how the human eye perceives patterns and worked on understanding the nature of light and color. Zöllner also studied the possibility of detecting extraterrestrial life by analyzing light signals from space. His experiments and observations contributed to the fields of optics and early ideas about space communication, making him a significant figure in both physics and the study of visual perception.
