You missed my point. If you look through the lens of science, the universe cannot be described as anything more than a mathematical system.

It seems it's you that missed the point, Maths is a language and so no more profound or fallacious than English; its use is the key factor.

Mathematics is more than just a way to describe the universe because it can be used to make predictions.

Although science tries to quantify things not everything can be described mathematically. 

And, of course, the fact that our brains are able to describe the world using mathematics doesn’t mean that the world is inherently mathematical. We can also describe the universe using poetry. It doesn’t mean it is a poem.

Mathematics is a fundamental aspect of the universe because it can make predictions about the universe.

That is because they are accurate descriptions and the universe is (luckily) consistent and predictable.

Huh? That is the most bizarrely illogical statement I have heard for a long time. It is close to "affirming the consequent" but less rational.

Mathematics is clearly fundamental to how the universe operates, which is why it is a fundamental aspect to the universe.

Ever heard of a weather report? It uses language to gain and explain predictions.

That's like saying a storm is a fundamental aspect of English because it predicts it'll be wet and windy.

No, a weather report does not make predictions, it just explains them.

Equations are algorithms which take an input and produce an output. Mathematics makes predictions that we can measure and that are consistent. We can measure numbers but we can't measure "wet and windy" unless we have an idea of what "wet and windy" is.

So you don't have a service that tells you what the weather will be tomorrow on your planet? How interesting.

Relative humidity. Precipitation. Wind speed. 

I guess this ignorance explains why your assertions are completely baseless.

Have you heard of equivalence classes?

Not always, no.

 

How about the equation a=b ?

Where is the input, the algorithm and the output?

Weather reports explain what scientists predict. These predictions are based on mathematical models.

Those are mathematical quantities. If you considered that "wet and windy" then it could be something that you can measure, but "wet and windy" is a concept.

How does this statement relate to my statement that "mathematics uses math to make predictions"? Weather reports are based on mathematical models, so I don't know what your point is.

So why did you say it couldn't be measured? You are not making very much sense here. I can't take anything you say seriously.

The input is a, the output is b. The algorithm is the equation which describes how to get b from a.

So If I said what happens if I write the equation the other way round?

You have just defined a as the input, so how can it also be the output or is that a different equation?

BTW are twelve pence equivalent to one shilling?

Because it depends on what you consider to be "wet and windy". If mathematical measurements and quantities are interperted as "wet and windy" then wet and windy can be measured.

I understand what equations are and how they are used. Physics is based on equations and functions, to say otherwise is clearly wrong. There is no other system which can be applied to physics to make predictions other than math.

It's not mathematically wrong to say that the output is b if a=b and a is the input.

It doesn't matter what you define as the input. There is nothing preventing a from being both the input and the output.

Physics is a fundamental aspect to how the universe operates, and mathematics is fundamental to physics, so mathematics is clearly a fundamental aspect of the universe. I don't see what your point is. Are you refuting that mathematics is fundamental to the universe?

Which just proves what I said

If the output = the input I have an equation, but no algorithm has taken place.

 

By the way why have you not answered my earlier question about Godel's theorems

The problem is that you are to all embracing with your assertions to the exclusion of other equally valid possibilities.

If you had said one type or use of an equation is "whatever you said" that would be OK.

BTW2

Do you know the difference between an equation and an identity in mathematics?

It is our attempt to describe how the universe works.

I am saying it is not obvious. Having read some arguments on both sides, I am not convinced that the universe is fundamentally mathematical.

If you had some argument beyond your personal belief, there could have been a useful discussion but "the universe is mathematical because it is mathematical" is not very compelling. Neither is "the universe is mathematical because I say so". I am not really interested in your personal beliefs, however strongly you hold them.

Algorithms are rules which describe how to get an output form an input. In the case of the identity a=b, the rule is that you don't do anything to the input. That means the algorithm is doing nothing to a.

My assertions are reasonable. It is reasonable to state that an equation is an algorithm which takes an input and produces an output. There is nothing wrong with that statement.

An identity is an equation where no operations are performed. That is, a=b is an identity because it is an equation where two quantities are equal without any operations being performed on either.

You don;t understand the argument I am making. My statement is not "the universe is fundamentally mathematical" but "mathematics is fundamental to the operation of the universe". I never said that the universe is only mathematical. It's not personal belief to state that mathematics is fundamental to the operation of the universe when all of physics is based on mathematics.

I don't believe it is. And you have not provided any convincing reason for me to change my mind.

That is a non-sequitur.

Physics is a description of the universe. Therefore our description of the universe is based on mathematics. A description of the universe is not the universe itself.

"A map is not the territory."

Maybe you should do an introductory course in philosophy so you understand what logic is, how to avoid fallacies, and the difference between a signifier and the signified.

You have already proved that you don't so there is no point repeating that. No one believes you.
