In 1953, Léon Brillouin derived a general equation stating that the changing of an information bit value requires at least kT ln(2) energy. This is the same energy as the work Leó Szilárd's engine produces in the idealistic case. In his book, he further explored this problem concluding that any cause of this bit value change (measurement, decision about a yes/no question, erasure, display, etc.) will require the same amount of energy.

1953年，布里渊推导出一个一般性方程，说明改变一个信息比特值至少需要 kT ln (2)的能量。这与理想情况下 Leó Szilárd 引擎所产生的能量相同。在他的书中，他进一步探讨了这个问题，得出结论: 任何原因产生一个比特的改变(测量、关于是/否问题的决定、擦除、显示等等)都需要同样的能量。
