Math models reality with abstract constructions
Welcome to the fray Agobot,
I'm going to answer in a different vein than the others:
Physics contradicts maths - how is this possible?
Because the math can be perfect and still wrong.
Contention - maths proves that in theory moving objects should never touch each other, physics shows the opposite.
Because the math can be perfect and still wrong.
How is this possible?
Because the math can be perfect and still wrong.
Math is based entirely on assumption, it is an intellectual abstract construction, and not part of the objective world, ie - "1" does not exist in the objective world, only in the abstract world.
As such there is no real tie between any mathematical computation and any object of the world of objective reality. Math can be used to model reality, but the model is only as good as the assumptions used in the maths, and thus whenever math and reality contradict one another it is the math that is wrong.
Bees fly. An engineer calculated that it couldn't, but it was the assumptions that the aerodynamics of man-made plane wings to the flight with bee wings that was in error.
Finding these contradiction improves our understanding of reality and our ability to model it, with theory and math.
Enjoy.

Re: Math models reality with abstract constructions
But, we've had this conversation before.
We have, and I can understand your point of view, where you are coming from.
It's just not applicable to flexible-wing aerodynamics. The problem is not the math but the model.
Which was mathematical.
Instead, the math can be perfect but not applicable to the situation at hand.
A wrong use\application of math\model still means the math is wrong for the situation, no matter how perfect it is for other use\applications.
We'll just have to disagree.
Enjoy.

Re: Math models reality with abstract constructions
... you're trying to use a screwdriver when the situation requires a hammer ... It just isn't a hammer.
Funny, I almost used that same analogy in my last post.
The way I see it, the math\model gives the answer "2" ... and even though the calculations are correct, the answer in reality is "3" ... and that makes the answer just plain wrong no matter how perfect the math and correct the calculations were.
Modeling math with hammers and screwdrivers won't change the fact that the mathematical answer is wrong.
