    Jack,

    So sorry to be so late. I've been working hard these past couple of months on a "history of information."  It's a trick to be rigorous enough to get the thermodynamics and information theory right, but not so profound as to overreach my own limitations or the interests of those outside those fields. Please let us know what you learn in those books. I will get to them when I can, especially if you think that they are truly on to something. As I've stated before, more or less, at least there isn't any current consensus in the scientific community that we understand the basic property of physics, chemistry, or some other force that predicts the emergence of life, although we know a lot about what seem to be prerequisites as it exists on this planet.

    Ken,  found the Smith and Morowitz book just "too much" -- not wrong, just a ton of elaboration. The original Santa Fe Institute article which I believe I sent you is much easier to work through. 

    As to the feeling that you don't yet have enough 'why', I just ran across a very nice transcript of an interview with Feynman on why questions -- http://lesswrong.com/lw/99c/transcript_richard_feynman_on_why_questions/

    I also like a statement of Jess Brewer, emeritus prof of physics at British Columbia 

    Arguably all physical knowledge is “existential” in the sense that we observe what happens and try to develop a formalism that describes it in enough detail that we begin to feel familiar with it — pretty much the same way we learn how our bodies work.

    So if you marry Brewer and Feynman, as to 'why' life, you might come up with something like --  the non-equilibrium thermodynamics of the U, in dissipating the differentials which it creates by correlative mechanics, has found efficiency in doing so by exploiting patterned processes of energy flow (differential dissipation) which topologically and multipicatively replicate themselves, using coding systems (genomes) to guide the development patterns of the processes. 

    The problem with that, in Brewer's framework, is that at the moment not many are 'familiar with' that perspective. But I am trying to replicate it, so to speak. The MS is near copy editing stage.

    So Feynman is wryly saying that before you can answer a question, you need to know how much context and how much resolution are you expecting in the response. Well, it would be good to know as much context and resolution regarding the origins of the simplest life form as we believe we do about star formation.  Of course, that's easier to answer because it is less complex, we can look at many examples across in the galaxy at various stages, sizes, etc. We know much about the context of life (its characteristics, likely use of carbon, some replicative process, etc.), but I don't our resolution to the question as to how it originated is very profound: probably began on Earth about 4 million years ago when conditions were different than today, unless you subscribe to panspermia.  Look forward to your manuscript.

    With a little more probing of Feynman's explication, one might say that he is pointing out that any event of the level of complexity entailed in life is a combination of many elements, one, and, two, that our means of characterizing the electromagnetic phenomena  which underly and produce the complex activity which are us are perhaps limited in adequacy because of their remoteness from the contexts and resolutions we are familiar with at our level of activity. Note his reference to what we are permitted to know. 

    But I, no more than you, want to fall into the 'there are things we are not meant to know' and 'handwaving' postures which we encountered so much in our formative years.

    Ken, et al, I m finding that the Smith and Morowitz  book does have a quite detailed exploration of just what sort of chemical reactions, against just what sort of planetary characteristics, were likely to energetically and chemically have bootstrapped life. 

    If you can find enough time to wade through the first 50 -70 pages, then skip to p 141, and then go to page 170 and proceed from there a bit, you will see what I mean.

    Ken, et al, here is a recent article which reports an attempt to translate 'information' between quantum and classical states

    This is a reply to an earlier post of Ken in which he characterized information as 'Relationships among (I say quantum))systems in space time' (the parenthetical is my own)


    De Gruyter has published my "order theory" book, entitled "Fundamentals For the Anthropocene" Here is a link to the open source availability

    https://www.degruyter.com/viewbooktoc/product/496571?rskey=PH6hIm


    Ken has referred me to an informative  website of a friend of his, http://www.informationphilosopher.com/

    After reading that website, I would probably retitle the third chapter of the book from "Correlation=Differentiation=Order" to read "Correlation=Differentiation=Order=Information"

    That is, along the lines of Ken's suggestion, each quantum system interacts with each other in such a way as to register a relationship, which also can be seen as 'information". 


    I read Rovelli's seminal work on Relational Quantum Mechanics https://arxiv.org/abs/quant-ph/9609002 to say that relational quantum mechanics is also a theory of information, and quantum interactions are information transactions, so to speak.

    in last post should have said second chapter of the "Fundamentals" book instead of third chapter.
