### Questions about mathematical models of the real world

Mathematicians typically define as little as possible, so that their results are as generic as possible. If they found a need to have a "BankAccount" type, it would be because we needed ...

### Questions about mathematical models of the real world

Representing a brick in maths is done differently depending on which attribute of the brick you wish to build into your model that has bricks in it. For example, if you wish to build a model which ...

### Is there a paradox in the proof of Godel's incompleteness theorem?

I'm not entirely sure that I'm justified in rejoining this question by way of a full answer, because I'm not entirely sure as to the justification of the question itself. But so I've decided to read ...

### Is there a paradox in the proof of Godel's incompleteness theorem?

Cogito ... Gödel's argument is that in a given axiomatic system capable of math, call it A, there is a statement/mathematical theorem, call it T, such that: T is true T is unprovable in A A few ...

### Is there a paradox in the proof of Godel's incompleteness theorem?

In my paper, there are two core ideas that are mutually corroborating and well-documented. I found a paradox in the proof of Gödel's Incompleteness Theorem and found the concrete form of the paradox. ...

### Is it possible to do physics without mathematics?

A fundamental question in the philosophy of physics is whether physics can stand independently of mathematics. If we were to take remove the support of mathematics from physics, what will remain? ...

### what's means scope of further modal operators?

sry I understand now, □◇∃a∀x(x in a iff {Fx}_1) is Fx within □ but not within ◇ because □ occurs at first and {Fx}_1 say Fx falling within the scope of the first 1 modal operator which Fx occurs in ...

It’s quite simple mathematics and would fit there better than under “philosophy”. But basically, you are misunderstanding what the statements mean. Assuming that every coin throw has a probability of ...

### Is Intuition Indispensable in Mathematics?

You may be confusing the concepts of Intuitionism and metalanguage. It is the latter that - implicitly or explicitly - underpins all work in mathematics and of course especially in logic. The ...

### If mathematics isn't fundamental to the universe, will we need to develop a new, non-mathematical approach to physics?

OP: “Physics, as a discipline, aims to understand reality at its most basic level, and mathematics is deeply ingrained in modern physics. However, if reality doesn't truly conform to laws expressible ...

### Can there be mathematical facts of the matter without mathematical realism?

Yes. If mathematics is more like a structured language imposed upon the universe by minds, rather than an external truth being discovered by minds, then the truth of the statements are true if the ...

### Is it possible to do physics without mathematics?

IMHO, it is possible to do physics without any underlying mathematics, but you will not go very far. The main goal of physics is to build a model that is able to reproduce what is observable in the ...

### Is it possible to do physics without mathematics?

I am not a philosopher but an ex-physicist. I also taught physics. The clear answer is no. There is no need to look for contrived reasons - whatever you do in physics is measured, and you need to have ...

### If physics can be reduced to mathematics (and thus to logic), does this mean that (physical) causation is ultimately reducible to implication?

The simplest law of quantum physics ( Heisenberg's uncertainty principle ) states that you cannot accurately know the position and velocity of elementary particles. Therefore, by definition the future ...
