  1. Here is something I grapple with. Religion defines God a certain way but when I observe nature I can see that what appears supernatural fits to the evolving theories of physics.
    #God everybody wants to own the correct definition of the Ineffable. Here are a few thoughts: http://thelenaghioparadox.blogspot.ca/2017/05/science-vs-religion-new-argument.html

  2. http://nanoscale.blogspot.com/2015/06/what-is-quantum-coherence.html
    … What is quantum coherence?

    Matter (diffraction)(interference) suffers Hund's paradox versus thermodynamics. A molecular beam of all right or all left "shoes" must diffract to give equal numbers of both in the exit pattern. This both mandatory and easy to sabotage...by a factor of 10^(-36,000)/second. Somebody should look,
