(1) I think you have a huge misconception here and you're clumping and stereotyping based on what seems like a personal experience of yours (I also notice not much of your opinion has changed since I last talked to you, further enforcing your bias). I'm pointing this out because it may very well be impossible to have a progressive discussion with you at all.
I think it's rhetorical of you to declare that I'm the one exhibiting bias, misconceptions, and stereotyping. You aren't too bad at wielding bias yourself. For example, down below and in preceding comments you've made the statement "pure mathematics is void of reality": well this is simply assuming your own conclusions! The only reason to say this is if you're already assuming that mathematics is something derived from the human mind with no external existence.
And also I'm not making these criticisms out of the blue, I was responding to what turbo said. He proposed,
"It seems that our mathematics cannot be used to construct reasonable models of the quantum world." And only when I resisted this did he refine the statement into a concern about the
application of mathematics by physicists.
That's exactly the kind of behavior I'm talking about.
Physics is what's concerned with describing the tangible world; that task is not a goal or objective of mathematics. That's why the proposal, "some physicists had difficulty describing what they're studying using mathematics - there must be something wrong with maths!" seems like a blame-shifting game to me.
Even if there are actually phenomena that can't be modeled with mathematics, that would have no bearing on the nature of mathematics; at least not so far as whether some aspect of mathematics is independent of the human mind. There's no reason why "must be able to describe everything in physics" would be a necessary attribute of a mathematics that is independent of the human mind.
If you really can't see how so many of these arguments are bent around physicist taking a utilitarian or instrumentalist perspective on mathematics - conceptually assuming that it is subordinate or otherwise incidental to physics - I think
you are the one approaching this with bias.

(3) Actually, if you'd free yourself from your bias of my line of thought you'd see that I outright admitted that science has flaws inherent to it. But the point is that pure mathematics is void of reality. You have to attach qualitative meaning to it for it to describe reality at all. Of course science makes flaws describing reality and mathematics doesn't; mathematics doesn't attempt to describe reality. Science uses mathematics because it's more accurate than language, not because it perfectly describes anything.
Okay, that's great. It still doesn't explain why some difficulty scientists have in employing mathematics for modeling phenomena has any relevance on whether or not the subject of mathematics has existence outside of the human mind. (And, as I pointed out above, declaring mathematics to be void of reality is assuming your conclusion.)
I think it's just fine to say
"science makes flaws" in this regard, it's when that's extended to mathematics, and pretenses are made such as suggesting that the development of quantum theory entailed some portion of mathematics being scratched out and rewritten - which it did not, it was
science that had to be rewritten - that I take issue with and which appears to me to be a case of someone projecting the problems of science upon mathematics.
Pythagorean said:
(4) Do you see how you're expecting exact relationships (right down to the name of the religion) for theology, but you'll willing to be much more loose about the relationships between the mathematics of different species?
No, I'm not. Buddhist theology contradicts Christian theology, for example, and even the most broad principles of theology of particular sects within a single religion are often completely contradictory. No matter what things were named if an alien culture posessed an independently-developed theology that in every metaphysical precept was in agreement with and compatible with a particular Earth religion that would be staggering.
Whereas conversely, however an alien culture expressed mathematics, even so specific an agreement as the fact they'd arrived at the exact same value of
π would be unsurprising. Or, for example, even if they had never discovered the Pythagorean theorem and did not have the concept of triangles, we would expect nothing in the Pythagorean theorem to contradict anything within their mathematics and vice-versa. A small detail like 2 + 2 = 5, for example, would irreconcilably break the Pythagorean theorem and many other things; but we would not expect to encounter anything like that.
This is not a case of theology and mathematics being approximately similar and I'm simply being picky about details. They're fundamentally different things.
Pythagorean said:
Science is somewhere in between religion and mathematics, making guesses about the universe, but using the mathematics (like you'd use a man made wrench) to make sure the observations themselves are consistent enough to make predictions about similar observations.
I think it's putting science on a rather high pedestal to assign it the role of mediator between religion and mathematics. I think most theologians (and I have known a few) would assert that they don't end up going anywhere near science if they need to apply principles of mathematics or logic to religion. (And you were criticizing me for bias? Mathematics is the wrench of science?)
And as I've said all along, it's wonderful that science finds mathematics so reliable that it invariably employs it this way. But that does not mean that the fundamental nature of mathematics is somehow integrally tied to its usefulness to scientists as a tool.⚛
