Symbol T

The passage around this formula

…the entropy the erased information represented has to go somewhere, and the second law of thermodynamics says it can only go up [ 1 ] . The minimum energy that erasing one bit must dissipate, at absolute temperature T , is: $E_{\min} = k_B T \ln 2$. where $k_B$ is Boltzmann’s constant. At room temperature — 300 kelvin, a reasonable stand-in for a chip’s operating temperature — plugging in Boltzmann’s constant’s exact SI value gives:
