    Fabrication process for the conductive microtubules. (a) Spin coat a thin layer of liquid polymer (here, Ecoflex 00-30) onto a silicon wafer, (b) rolling coat the carbon rod with the thin layer of liquid polymer, (c) heat with a hot plate, (d) peel off the hollow microtubule, (e) inject liquid metal (EGaIn) into the hollow microtubule using a needle and syringe, (f) insert electrodes into both ends of the microtubules and twist. Structure of the microtubules with (g) different numbers of turns per twisted pair, (h) woven electronic sensing fabric using twisted conductive microtubules. Detail: Cross-sectional SEM image of microtubule. Bar scale: 100 µm.

    Microtubule networks.

    Fig. 2.
    Effect of the shape on the MT network organization. (A) Protoplasts expressing MBD-GFP reporter confined in microwells of different geometries showing the effect of shape on the MT network organization. All size standards are 10 µm. (B) Cumulative distribution of the average angle of the MT network for the various geometries tested. Number of protoplasts N = 44 and number of repeats n = 12 for triangles, N = 48 and n = 10 for rectangles, N = 38 and n = 11 for squares, N = 26 and n = 7 for circles, and N = 22 and n = 4 for controls. (C) Boxplot of the anisotropy of the MT network in the different geometries tested. The number of protoplasts N and number of repeats n are the same as in B. (D) Example of the MT arrangement at the end of numerical simulations for a square domain and a rectangle domain. (E) Graph of the average angle of the MT network in rectangular and square shapes from numerical simulations of tsteps = 10,000 time steps, R = 50 repeats, and Pcross = 0.005 (with severing of MTs). (F) Anisotropy of the MT network for rectangular and square shapes in numerical simulations of tsteps = 10,000 time steps, R = 50 repeats, and Pcross = 0.005 (with severing of MTs).

    NIH scientists take totally tubular journey through brain cells
    Study may advance understanding of how brain cell tubes are modified under normal and disease conditions.

    Fantastic Voyage. NIH scientists watched the inside of brain cell tubes, called microtubules, get tagged by a protein called TAT. Tagging is a critical process in the health and development of nerve cells.Roll-Mecak lab, NINDS, Bethesda, MD

    All based on Life and energy and matter .

    Life manipulates , and feeds from minerals in deep Earth's crust .

    The Intellect will take the periodic table and manipulate it . Advanced thinking .

    Naahhh. That concept requires "irreducible complexity". But self-organizing substances are not irreducibly complex.

    Intellect is not required for this type of self-organization. These are purely natural mathematical functions based on the interaction of physical potentials, like electromagnetism.

    Life and intellect .

    Exactly . The physical . Neither electricity nor therefore the electromagnetic field can exist without the physical . Neither can light , from stars .

    No, this started long before life and intellect evolved from purely chemical intereactions and pattern forming. I mentioned it before . Chaos Theory.
    But I don't dispute that. Natural selection almost always settles on the most efficient physical expressions and patterns are mathematical in essence.
    Example: Symmetry
    Automorphisms of algebraic objects
    https://en.wikipedia.org/wiki/Symme...try_in_quantum_mechanics:_bosons_and_fermions

    Now consider microtubules that are responsible for symmetrical cell division. Little computers making copies in accordance with chromosomal instructions, resulting in symmetrical (chiral) organisms.

    What did you prove ?

    I think I proved that the universe has quasi-intelligent Logical essence that guides all universal physical phenomena.

    This becomes expressed in the chronological evolutionary self-ordering processes, including the emergent phenomenon of consciousness. This chronology is observable (with some gaps) from the fossil record that clearly show a very chaotic primitive dynamic environment where self-ordering patterns evolved from chemistry into abiogenesis and eventually into intelligent organisms. There is no mystery in that demonstrable chronology.
    The problem is in the really small details such as the role microtubules played in this evolutionary process, that we are now intensively studying all over the world.

    What of reason ?

    Seems to me that is a human quality.

    As to purpose? Perhaps it was necessary, given certain sufficient potentials.

    Its any advanced being Quality . Reason .

    Purpose , to understand , objectively .

    Logic is based on the reasoning at that time in history , whether it be Now , the past or the Future . And reasoning is based on the knowledge known at that time and the intellectual attitude of the mainstream thinking at that time . And the creativity of those at that moment in history . The 1900's was much more open minded than we are now . Logic is based on the Reasoning .

    I disagree with the order you suggested.
    Reasoning is a thought process and is based on understanding of Logic, which is a function of cause and effect.

    Logic OR Function

    What causes , effect and then affect is based on knowledge . Then reasoning occurs .

    Logic can not exist on its own , it needs to be based on something . Knowledge . Then reasoning , then logic .

    Mathematics is not reasonable. It is logical in abstract essence.

    IMO, the existence of the universe itself is not necessarily reasonable, but somehow it has to be logical.
    Else it would not exist.

    Logical , the Universe exists because nothing can never exist . Nothing has no dimensions fundamental to existence , length , breadth and depth . And nothing can never evolve nor transform into something . Something has all three . Hence exists . As you can sense . And before our senses .

    I agree, but existence logically does not necessarily have to be physical. After all the 3 spatial dimensions plus 1 temporal dimension are non-physical "conditions" that nevertheless seem to govern all abstract (logical) universal laws of symmetry, balance, motion, gravity, etc, and according to Tegmark about 31 numbers can describe all the values and equations that make up the universal physical potentials.

    Perhaps it is impossible for nothing to exist. The sentence itself is a contradiction in terms.

    The Sentence in my post#198 got you to understand nothing .

    I agreed with your sentence in post #197 that I quoted in my post #198, because I understood what you said, but added another perspective to it. Perhaps that may have escaped you?
