“The absence of a neocortex does not appear to preclude an organism from experiencing affective states. Convergent evidence indicates that non-human animals have the neuroanatomical, neurochemical, and neurophysiological substrates of conscious states along with the capacity to exhibit intentional behaviors.  Consequently, the weight of evidence indicates that humans are not unique in possessing the neurological […]

Main Points A homogeneous phase can be spontaneously decomposed into two immiscible phases. Concentration gradients can be spontaneously formed at the border between immiscible phases when the system reaches its equilibrium state. At constant temperature and pressure the entropy of system in question spontaneously decreases during the separation process. In the adiabatic system the increase […]

My messages to the biosemiotics list (see the thread Conformons as the sound of cell language) with comment to H. H. Pattee, How Does a Molecule Become a Message? Communication in Development Proceedings of the 28 th Symposium, The Society for Developmental Biology, Boulder, CO, June 16-18, 1969 Editor-in -Chief ~ M. V . EDDS, […]

I will start with a quote from Spyridon Kountroufinis, Teleodynamics: A Neo-Naturalistic Conception of Organismic Teleology, In Beyond Mechanism: Putting Life Back Into Biology p. 322 “This essential property of dissipative dynamic systems is also known as the principle of maximum entropy production, which can be easily explained. According to the second law of thermodynamics, […]

One paragraph from J. Scott Turner, Biology’s Second Law: Homeostasis, Purpose, and Desire. In Beyond Mechanism: Putting Life Back Into Biology I should say that the book is good and the chapter actually is also not bad. Yet, this paragraph speaks for itself: p. 192 “At its most general, the disequilibrium that characterizes a living system […]

In an interview of Alexis Pietak, I have heard about Rat Park and now I have found information in Internet. Bruce K. Alexander Addiction: The View from Rat Park “In the 1960s, some experimental psychologists began to think that the Skinner Box was a good place to study drug addiction. They perfected techniques that […]

Rebecca Stott, Darwin’s Ghosts: The Secret History of Evolution A nice book. I have enjoyed listening to it. Below there are scientists, considered in detail in the book. An excerpt: Chapter 2: Aristotle Eyes – Lesbos, 344 BC The History of Animals, Parts of Animals Chapter 3: The Worshipful Curiosity of Jahiz – Basra […]

Recently I have discovered that biologists like MEPP (Maximum Entropy Production Principle): see Physical foundations of evolutionary theory and also the last slides in Does Entropy Play a Role in Biology? I have not found in the papers from biologists simple applications of MEPP. As I personally like to start learning a theory with simple […]
