The passage around this formula

The last major gap in this record closed two years later. Landauer’s 1961 principle had stood for half a century as a trusted but experimentally unconfirmed claim, mainly because dissipating and resolving a heat signal on the order of 10^{-21} joules from a single bit erasure was beyond available calorimetry. Antoine Bérut, Artak Arakelyan, Artyom Petrosyan, Sergio Ciliberto, Raoul Dillenschneider, and Eric Lutz closed that gap in 2012 with “Experimental Verification of Landauer’s Principle Linking Information and Thermodynamics,” published in Nature [ 9 ] . Rather than attempting calorimetry on an electronic bit, they built a colloidal analogue: a single micron-scale bead confined in a…
