1. Amongst all organisms with at least one cell, the mean number of cells it possesses is 1 + 10^___.
2. Amongst all organisms with at least /two/ cells, the mean number of cells it possesses is 2 + 10^___.
What are the integers that come closest to making these statements correct?

A surprising fact I learnt. If you count up every hour every human has ever lived up to the end of 2025, and you pick one hour at random, there is a →10%← chance that hour happened between 2001 and 2025.

Small confession to make: magit (as with git) does not actually specify any default message for your first commit, as it very well shouldn't. I don't like "Initial commit". I use "Brought forward", like it's an accounting ledger.

There is a certain pattern amongst some people of a particular religious persuasion, where the principle "nothing good comes without difficult times" becomes "difficult times precede good things", and finally "difficult times /is/ the good thing".

I'm looking for someone on Bluesky who posted a couple of nice worldbuilding pictures about a bunch of aliens. I remember that one of them has a base 8 counting system and "the villain of the story" (len(name) == 3) looks a bit like the picture attached. I saw it yesterday and then didn't save it.
