Entropy to the radiator. To estimate the entropy an internal reversible process is assumed, with the natu-ral logarithm. In the first and second term of the right-hand side of the equation above, the surface temperature of the radiator is placed in the denomi-nator. These terms represent the entropy flows leaving the radiator through the surface. ... Content Retrieval

Zero-point Energy - Wikipedia
The term zero-point energy In 1900, Max Planck derived the average energy ε of a single energy radiator, The second law of thermodynamics states that in a closed linear system entropy flow can only be positive (or exactly zero at the end of a cycle). However, negative entropy (i.e ... Read Article
