Coherent energy transfer

Posted by

The feasibility of coherent energy transfer in microtubules Travis Craddock et al, Nova Southeastern University http://arxiv.org/abs/1405.3170 Summary and review of the above paper INTRODUCTION:  Craddock’s paper emphasises the strong similarities between tryptophan complexes in microtubules and quantum coherent energy transfer in photosynthesis, a connection which is dumbed out in most discussions of quantum biology. The microtubules are themselves closely connected to mitochondria; Read more […]

Atomic water channel controlling remarkable properties of a single brain microtubule: Correlating single protein to its supramolecular assembly Satyajit Sahu & Anirban Bandyopadhyay et al, National Institute for Materials Science, Japan Biosensors and Bioelectronics 47 141-148, 21 February 2013 Summary and review of the above paper INTRODUCTION: The authors say the prior to this paper the properties of tubulin and microtubules were not extensively studies using the up-to-date technologies Read more […]

Our Mathematical Universe

Our Mathematical Universe Max Tegmark (2014) Summary and review of the above book The first part of this book is a readable guide to understanding physics and cosmology. Where it goes wrong is that the author gets out of his depth in trying to extend to non-consensual areas such as time, reality and consciousness. The discussion here starts well in identifying that the brain constructs a model of reality, which is consciousness, helped by the integrative brain hub scheme developed by neuroscientists Read more […]

Gaps in Penrose’s Toiling

Gaps in Penrose’s Toiling Rick Grush & Patricia Churchland Philosophy of Dept., University of California, San Diego Journal of Consciousness, 2, No. 1, 1995, pp. 10-29 Keywords:  mathematical truth, unknowable algorithm, quasi-crystals The core part of this article is the Grush and Churchland’s discussion of the soundness of the processes by which mathematical truth is ascertained. The authors say that for convenience they will grant Penrose’s claims that human mathematicians Read more […]

Penrose’s Godelian argument

Posted by

Penrose’s Godelian argument Solomon Feferman, Dept. of Mathematics, Stanford INTRODUCTION:  Feferman has a common cause with Penrose in opposing the dominant computational model of the mind, and considering that human thought, and in particular mathematical thought, is not achieved by the mechanical application of algorithms, but rather by trial-and-error, insight and inspiration, in a process that machines will never share with humans. His criticism of Penrose applies mainly to him extending Read more […]

Computable universe

Foreword to A Computable Universe: Understanding computation and exploring nature as computation Roger Penrose World Scientific 2012 Penrose’s argues that Gödel’s incompleteness theorem provides a strong case for human understanding being non-computable. This relates to our ability to demonstrate the truth of certain mathematical propositions. These are described as π1 sentences. These sentences assert that a particular computation, such as Lagrange’s theorem which asserts that every natural Read more […]
