A Judgment Experimental Design About the Basic Principles of Newtonian Mechanics and the Second Law of Thermodynamics

Authors: LI WeiGang
Comments: 4 Pages.

This paper describes an experimental design similar to “Maxwell’s demon”. Compared with the “Maxwell's demon” scheme, the proposed experiment does not need intelligence that is necessary for “Maxwell’ demon” when working. Moreover, the program is not an ideal experiment only performed in thought. It can be implemented realistically. The design fully follows the basic principles of Newtonian mechanics but contradicts the second law of thermodynamics. The experimental design suggests that there is a logical contradiction between the basic principles of Newtonian mechanics and the second law of thermodynamics.

Demons: Maxwell’s Demon, Szilard’s Engine and Landauer’s Erasure–dissipation

Authors: Laszlo B. Kish, Claes-Goran Granqvist, Sunil Khatri, He Wen
Comments: 6 Pages. In: Proceedings of the first conference on Hot Topics in Physical Informatics (HoTPI, 2013 November). Paper is in press at International Journal of Modern Physics: Conference Series (2014).

This talk addressed the following questions in the public debate at HoTPI: (i) energy dissipation limits of switches, memories and control; (ii) whether reversible computers are possible, or does their concept violate thermodynamics; (iii) Szilard’s engine, Maxwell’s demon and Landauer’s principle: corrections to their exposition in the literature; (iv) whether Landauer’s erasure–dissipation principle is valid, if the same energy dissipation holds for writing information, or if it is invalid; and (v) whether (non-secure) erasure of memories, or the writing of the same amount of information, dissipates most heat.
