Ostrich unhappy with my attempt to recall some basic facts about continuous time Markova chains and branching processes

Unbeknownst to me at the time, yesterday was fountain pen day which may explain why I found myself doing a few sketches and taking lots of notes while reading Harris's book on branching processes 😜

Yes - isometric scaling as a way to understand the benefits and costs of being small versus large. Haldane's Harpers article from 1926 is an amazing example of popular science writing.
