    Cover of Wang's Carpets

    Wang's Carpets

    Greg Egan · 2012

    Far in the distant, post-human future, the Cater-Zimmermann community set out to refute the theory that the universe is created exclusively for mankind by cloning themselves a thousand times over and sending each copy to a different star within the galaxy. One of the copies of Cater-Zimmermann, Paolo Venetti, arrives at Orpheus; a water-world inhabited by floating mats that perform as a Turing machine.

      Greg Egan's work has its share of humans but also some extremely imaginative aliens. I am not sure who can relate to the aliens in Wang's Carpets.

      Greg Egan is a very good example of a novelist who is a GOAT but will be dismissed by most critics of lit-fic because "his characters don't have arcs" or some such.

      Add Diaspora by Greg Egan to the simulated minds reading list (the story Wang's Carpets within it is one of my favorites).

      You might be right but...

      If this world is a simulation knowing the nature might let us work with it better. Hacking the universe (maybe or maybe not if a simulation). It would in some ways just become an extension of physics (in effect).

      This gives me an opportunity to bring up a favorite story of mine.

      Greg Egan has some fantastic writing on considering extra-dimensional space. See Wang's Carpets as the basis for https://en.wikipedia.org/wiki/Diaspora_(novel)

      For sci-fi readers that dig aperiodic tiling, Greg Egan wrote a great short story in his book 'Diaspora' about computational wang tiles. http://www.amazon.com/Diaspora-Greg-Egan-ebook/dp/B00E83YOEI (the short story is titled Wang's Carpets, available separately as well, but the whole book is worth buying or checking out from the library).

      I hope this is considered on topic. I find fiction, particular that which inspires interest in math/code to always be particularly relevant.
