| Description | This is an overview article that contains the discussion of the connection between information and physics at the elementary level. We present a derivation of Landauer's bound for heat emission during irreversible logical operation. In this computation the Szilard's version of Maxwell's demon paradox is used as a model to design thermodynamic implementation of a single bit of computer memory. Landauer's principle also motivates the discussion on the practical and emergent nature of the information. Apart from physics, the principle has implications in philosophy. |
