    Can complexity have a negative value? Because progress sure can. It's then called regression.

    Depends how you view it ;-)

    In technology - probably. But in science - isn't progress a wider understanding using fewer, more basic principles?

    Don’t you have to analyse as much data as you can justify as necessary in order to derive basic principles?

    Oh, and I forgot to add, isn’t it true that the more you know, the more you realise you don’t know?

    Analysing complexity to understand its underlying principles is going from complex to simple, Shirley. And the more profound the simple principles, the more complexity they can reduce. Agsin going from complex to simple.

    It certainly explains Turd

    But surely that assumes a finite number of simple principles. Is that how spacetime works?

    Physicists fervently hope so.That is the core of theiŕ faith.

    So what is complexity?

    Different question. We're arguing about relative complexity. The absolute argument is more expensive.

    I’m not arguing about relative complexity, I’m positing that “progress” is a cypher for complexity

    I think you are arguing that progress is increasing complexity. If we talk about "complexer" isn't that relarive to " less complex"?

    To re-iterate my point I think that progress in science consists in simplifying things. Information entropy is negative.

    If you’re saying that building something like CERN or the Hubble telescope is simplifying “things”, I don’t agree!

    Yet many of the operating principles of those two wildly disparate science projects are identical and can be described, predicted and controlled by the use of a few "simple" mathematical relations. For certain values of "simple", some of which are truly simple by any definition, of course.

    Research shows the 'magic range' of twisted bilayer graphene is larger than previously expected.
