Is information energy? This thread was inspired by a conversation https://www.physicsforums.com/showthread.php?t=419343". I thought we got a little off topic, but the conversation is worth continuing. The idea seems to stem from http://en.wikipedia.org/wiki/Landauer%27s_principle" [Broken] that states that "any logically irreversible manipulation of information, such as the erasure of a bit or the merging of two computation paths, must be accompanied by a corresponding entropy increase in non-information bearing degrees of freedom of the information processing apparatus or its environment." The paper is http://www.google.com/url?sa=t&sour...tTgBA&usg=AFQjCNEgG29b9aHMFGZ7D1RCM3c70eQ_Vg". This seems to indicate to me that it is the computational process rather than the information itself that increases entropy. It reasons that any type of computation would increase entropy since computation is work. Is it generally accepted that Landauer's principal equates information to energy? If not, is there another principal/law/etc. that does?
