What a wonderful lecture. Thank you for uploading this very useful video. I have watched it twice. Amazing how this professor put some much time in preparing those demonstrations. I got embarrassed because I also teach university students, but I am so far compared his clarity in explaining the topics. Wonderful. BTW: the instructor "Professor George Porter" won the Nobel Prize in Chemistry in 1967 (shared with two other professors).

Misunderstandings in ideas about entropy and second law Many misunderstandings in understanding the problems of life and evolution from the standpoint of physics and physical chemistry are typically associated with misconceptions in understanding entropy. The term "entropy" coined Rudolf Clausius. According to his "model" of the world (universe), he presented a statement: "The energy of the world is constant. The entropy of the world tends to the maximum". Later this statement was chosen by JW Gibbs as an epigraph to the paper "On the Equilibrium of Heterogeneous Substances". These scientists have given this statement in relation to their model of the universe. This model corresponds to a simple isolated system of ideal gas, i.e. isolated system of ideal gas, energy and volume of this system are constant and in which only the work of expansion is performed. Entropy of such a system can only increase! It should be noted that when we say on ideal model, which would correspond to the real universe, it would be necessary to accept the unreal assumption that any form of energy real universe will be transformed into thermal energy. Only in this case, also under additional unrealistic assumptions, the real universe "would turn" into the model of ideal system of Clausius - Gibbs. However, lovers of science have applied representations on simple systems to systems of other types, in which the interactions takes place between particles of different nature (interactions of molecules or other objects of different hierarchies) and to systems which interact with the environment. Some scientists, who are not professionals in the relevant fields of knowledge, have not escaped such errors. This has led to unimaginable confusion. This has slowed down the development of science, more than on a century. There are thousands of publications in scientific journals and popular literature containing marked misunderstandings. To these were added incorrect ideas on the negentropy and on the dissipative structures in the living world, and the false identification of "the information entropy" with the thermodynamic entropy. The origin of life and its evolution can be easily explained from the standpoint of hierarchical near equilibrium thermodynamics of complex dynamic systems. This thermodynamics established on a solid foundation of equilibrium thermodynamics - thermodynamics of Rudolf Clausius, JW Gibbs and other great scientists. www.membrana.ru/particle/17266 See also: On General Physical Principles of Biological Evolution www.researchgate.net/publication/314187646_On_General_Physical_Principles_of_Biological_Evolution

None of that matters, because entropy proves the sky is not a vacuum and outer space doesn't exist. Entropy proves atmospheres could never even form in a vacuum to begin with. Bye bye Heliocentrism. Bye bye Big Bang. Bye bye evolution.

In order for universal constants to persist, the process (mathematically) of modulation (eg from Planck's Constant), and demodulation/integration of energy, then the subsystem selected is rotating and reflecting out of the local structure of the choice of parameters. Just like an arrow dissipating the energy of the bow in a selected direction, a subsystem does the same. Nothing wrong with the lecture, it's a mark of progress in the normal way, that for the era, everyone did the best they could with what they had, and changed the world. (another subsystem)

The statistical approach is now generaly concidered to have the same problem of still being time-symetrical and local on molecular levels. As people like Prigogine have described in the 70-80's there are better (yet unfortunatly more difficult) ways to get real irriversable processes in non-lineair/far-from-equilibrium dynamics.
