From this article about a different emperor: https://www.lrb.co.uk/the-paper/v41/n04/christopher-kelly/a-...
Lots of thoughtful sf book reviews with a heavy (but not exclusive) focus on the New Wave.
"In modern mathematics, an analytic theory is one whose basic objects are defined in some other theory, whereas a synthetic theory is one whose basic objects are undefined terms given meaning by rules and axioms"—Michael Shulman
In programming terms, I guess "synthetic" mathematics feels a bit like programming to an abstract interface.

In the first part of this video Cédric Villani gives (in French) a nice explanation of the distinction: https://youtu.be/xzVk56EKBUI?t=258
Edit: an English explanation, also by Villani: https://www.youtube.com/watch?v=AIrLXbwyYXQ
> However, even for these tasks, its performance has dropped measurably since the early 2060s and is now considered subpar compared to more recent uploads. This is primarily attributed to MMAcevedo's lack of understanding of the technological, social and political changes which have occurred in modern society since its creation in 2031. This phenomenon has also been observed in other uploads created after MMAcevedo, and is now referred to as context drift.
Agree! And I would add that you can "purify" a monadic function without having to rewrite it in non-monadic style. You can make it polymorphic over all monads and relegate the "impurity" to monadic functions that you pass as arguments/dependencies. A trivial example:
twice :: IO ()
twice = do
putStrLn "foo"
putStrLn "foo"
twice' :: forall m. m () -> m ()
twice' action = do
action
action
This is not that different to having a Spring bean that doesn't perform any effect directly—say, a direct invocation to "Instant.now()"—but instead receives a "Clock" object through dependency injection.Haskell lets you express the idea of "program logic that only has effects through its dependencies" by being polymorphic over all monads.
Collections of marvels and extraordinary things were their own genre called ‘aǧā’ib. Here is an open-access example, "The Marvels Found in the Great Cities and in the Seas and on the Islands" https://library.oapen.org/handle/20.500.12657/46307
The classical world had a similar genre, paradoxography: https://en.wikipedia.org/wiki/Paradoxography
There's also the documentary "Sisters with transistors" about women pioneers of electronic music https://www.youtube.com/watch?v=7r-3hlzpV7M
