On the contrary, math is very useful in that it mimics nature.
So much so that science and technology co-opted it to make a myriad of shiny playthings.
Sometimes. Math can be used as a tool to create models of the physical world. However, 1) all models are wrong at some level, by definition, and 2) most models are failures, like the 80 models used to come up with the runaway man-made global warming scam, possibly the most expensive scam in history.
Math is interesting for being one of the few things that contains perfect truths. But nature is much more fuzzy, unknown, and for us mortals, unknowable.
