Holistic Reasoning The Second Law of Thermodynamics
It Can Be Challenged, But Cannot Be Violated*More at www.kostic.niu.edu
SPEAKING Enquiry
"It is crystal-clear (to me) that all confusions related to the far-reaching fundamental Laws of Thermodynamics, and especially the Second Law, are due to the lack of their genuine and subtle comprehension."
Definition of The 2nd Law: The useful-energy (non-equilibrium work potential) cannot be created from within equilibrium alone or otherwise, it only can be transferred between systems (ideally conserved) and dissipated into thermal energy thus generating entropy.
