It's interesting to consider the relationship between the infinity studied in #mathematics and the infinity that may exist in the real world, though ultimately this article doesn't have any answers.

I bet few people have wondered though, "if space is infinite, what is its cardinality?"

Hey, I just found out that there exists an annotated reading list of Mathematical Fiction: https://kasmana.people.charleston.edu/MATHFICT/search.php?go=yes&orderby=title

And that it contains an entry for my own story "Path Correction": https://kasmana.people.charleston.edu/MATHFICT/mfview.php?callnumber=mf1446

This story was published by Nature Futures in 2021 and can still be read online: https://www.nature.com/articles/d41586-021-02765-3
(Bragging rights: The only time I published in Nature, Nature paid me. 💃)

She freed physics, but couldn’t free herself. On Emmy Noether, whose mathematics slipped the bounds of the physical world even as her own life remained tightly constrained.

My first, favorite and most important sequence, the weights of prime numbers: A117078
We see prime numbers classified by level and by weight on the graph.

A117078: a(n) is the smallest k such that prime(n+1) = prime(n) + (prime(n) mod k), or 0 if no such k exists ➡️ https://oeis.org/A117078
