Thermodynamics: Energy, Heat, and Their Laws
Thermodynamics studies heat and energy principles, explaining their fundamental laws and impact on everything from engines to life.
What was corrected
The article said the second law is the only fundamental law distinguishing past from future, defined entropy as disorder, implied Szilard showed measurement necessarily has a thermodynamic cost, said entropy completely explains memory and causation, and said greenhouse gases are transparent to incoming solar radiation.
Qualified the time-asymmetry and greenhouse claims, refined the entropy definition, corrected the measurement-versus-erasure cost per Landauer and Bennett, and framed the arrow-of-time account as leading rather than complete.
Why this is better
These are physics-accuracy refinements: the statements were common simplifications that overstate settled physics. Corrections align them with the standard understanding rather than adding new sources.
