If you liked Clojure then you might want to try ClojureScript.
Haskell is interesting. For example, you can implement a poor man's Prolog in a Haskell list comprehension.
APL looks interesting and very alien to me. I assume that since it is array or matrix based that it is similar in some ways to Matlab, et cetera but the way people talk about it kind of makes you want to dive into its culture and at least read the original paper on it.
Maybe you should take your turn at inventing your own language?
I have fond memories of reading this book in college. I enjoyed it immensely.
I also remember reading the section at the back of the book about Galois. There was also an entertaining section about the history of solving the roots of polynomial equations and in particular solving equations of arbitrary order.
There is an ExploreGPTs feature that OpenAI provides. Has anyone experimented with trying to make one of these that successfully does what you want (e.g. more concise, better code examples, whatever)?
Vinge is certainly one of the greats but so is David Brin. I would not consider him under the radar though. Some of his best are Earth, The Heart of The Comet, Glory Season.
