Seems like this is easier when you deal with “ordinary” amounts of stuff, not too little and not too big. I don’t mean “mind-bogglingly, philosophical big”. The trouble is already in the 10^-5-ies. And I’m saying this because I take good apochromatic optics for granted, so can’t be too opposed to more pessimistic estimates.
I was so frustrated when I had to read up on phytohormones in non-flowering plants (and on the flowering, since they are better studied). It’s a crazy vinaigrette of units used to express what is usually quite low concentrations, with a few exceptions like pollen. How can one compare ng/g dry material to, say, mg/g wet material, when it is clear that these aren’t just two convertible figures but two different ways of measurement? (With who knows how many plants used to squeeze it out in either case.)
BTW, ChristianKI adviced me to read Husserl, but I haven’t yet (although what little I have read seems interesting and relevant).
