The branch of physics dealing with the way the laws of physics apply to living things.
"When Scientology established biophysics, it did so because of the various discoveries which had accumulated concerning mental energy in its reaction against physical energy, and the activities which took place in the body because of these interactions. Biophysics only became feasible when it was discovered in Scientology that a fixed electrical field existed surrounding a body entirely independent of, but influenceable by, the human mind. The body exists in its own space. That space is created by anchor points. The complexity of these anchor points can cause an independent series of electronic flows which can occasion much discomfort to the individual. The balance structure of the body and even its joint action and physical characteristics can be changed by changing this electrical field which exists at a distance from, or within, the body." Hubbard, Scientology, The Fundamentals of Thought
