CaptainQuasar said:... we've been using words clumsily to be interchanging “real” and “discovered”. I guess when we've been saying “real” we've been trying to express something like “external to the human presence in the universe.”
Yes, and "real" isn't the opposite of "invented" either, in the sense I mistakenly took Pythagorean to be using it when snidely commenting on his remark "I think circles are very real, personally". Guns are both very real and invented, of course. Apologies, Pythagorean.
I still have a great deal of trouble with what is real and what is not real, even after having run threads here with these titles. Mathematics is indeed very real, Pythagorean, in the sense that it can make you spend hours trying to untangle its puzzles, and helps us to describe the universe. But it is after all only "squiggles on paper" as I think the mathematician Hardy said. Or was it Hilbert?
Where circles are concerned, Morodin's remark "The platonic circle is an idealized conception. The universe has no problem with wonky circles" seems to me very apt.
