Suggest 3 Non-Fiction Books on Different Subjects to Read Before or While Reading Project Hail Mary”

I’m primarily a non-fiction reader, but I only recently started exploring fiction. I’ve developed a habit of reading three non-fiction books at a time, each on a different subject, yet all connected in some way to the fiction book I plan to read. Since fiction often explores multiple concepts at once, the possibilities for these non-fiction selections are endless, ranging from history and the hard sciences to psychology, parapsychology, Botany and beyond.
