Top 25 Challenges to the Second Law of Thermodynamics
The second law of thermodynamics is the law that says usable energy runs down: heat spreads, gradients fade, and no cyclic machine can turn ambient heat entirely back into work. Prof. Daniel P. Sheehan, Professor of Physics at the University of San…
