My interest in biology isn’t driven at all by stories, history, or “adventure”, but rather by the awe-inspiring complexity and majesty of all the microbiological processes and their interplay.

Yes, it’s pop science, but last be year I read through Philipp Dettmer’s “Immune”, and the description of how the immune system continuously generates random/arbitrary sequences of nucleotides, builds the proteins that those sequences encode, and then subjects the resulting proteins to a “is this a ‘me’ protein or an ‘other’ protein?” gauntlet, the latter path of which allows the body to create antibodies for completely novel proteins... is just incredible.

I have an idle fantasy that, in the afterlife, I’ll be able to ask God questions like “so what are quarks made of?”, “why is the speed of light what it is and not any faster/slower? What would the universe have been like if the speed of light were several orders of magnitude faster/slower?”, “is there a single force that unifies all the ones that humans know about? What would the universe have been like if the weak nuclear force were just a tiny bit weaker?”, etc etc etc etc etc etc etc.

same inspiration but I wouldn't devolve it to 'pop science', it's simply less axiomatic than physicists and mathematicians would like. The fact there's 4 billion years of ecological change beyond the biological change just makes stuff hard to prove empirically.

esp. when physicists use things like the anthropic principle to describe our own universe.
