The passage around this formula

…extractable work. Szilard showed that the demon’s ability to extract work was tied exactly to the amount of information it acquired in the measurement — one bit of information corresponds to a definite quantity of work, kBk_B T ln⁡\ln 2 , where kBk_B is Boltzmann’s constant and T is the bath temperature. This is worth stating as an equation because it is the single quantity that recurs across the rest of this history:
