The Od Force: Letters on a Newly Discovered Power in Nature is a book written by Baron Carl von Reichenbach. The book describes a newly discovered force in nature called the Od Force, which von Reichenbach claims is responsible for many phenomena previously unexplained by science. The force is said to be present in all living things and can be detected by sensitive individuals through various means, such as the sensation of heat or cold. The book contains letters written by von Reichenbach to his colleagues and peers in the scientific community, detailing his experiments and observations of the Od Force. He also includes accounts of individuals who possess a heightened sensitivity to the force, referred to as ""sensitives."" The book caused a great deal of controversy when it was first published in the mid-19th century, with some scientists dismissing von Reichenbach's claims as pseudoscience. However, the book remains an important historical document in the study of the paranormal and the history of science.1854.
