=== The physics of computation is a field that investigates the physical limitations of computing, including how much energy is required, how long it takes, and how large the computing device must be. Information destruction is central to the field, as many operations in computing destroy information, leading to energy dissipation. The aim is to find general laws governing all information processing based on fundamental physical principles. Reversible logic gates like the Fredkin gate are a viable alternative to irreversible ones. They allow for minimal energy dissipation and can be created using principles of physics, such as the movement of balls through pipes. The principles behind reversible Turing machines, which use random thermal motion for computation, are similar to those found in the microscopic world of chemical reactions. The RNA polymerase enzyme is an example of a Brownian tape-copying machine that already exists in nature. ===
