Not quite

Physics is a branch of math with specific focus

A fusion of math and experiment

On reality, yes.
And never tell that to a physicist.

I'm a physics nerd. I know how they can be.

;D

The robots are becoming sentient

Someone call Will Smith

I think it wants to warn me of something...

The smiley maybe

Where was I? Right.
Maths deals in too many abstract concepts to be considered a model of only reality. Otherwise, what are imaginary numbers. Negative numbers, even! Those only exist in our mind as logically possible. Also maybe in some deep-ass particle physics.

Actually. Imaginary numbers do model reality. Especially in the use of fractal geometry.

Do tell.
I like when people explain things.

In a sane view, those things should not exist, but I know full well not to trust my common sense.

Here

See how they are used in real life applications

Oh, I see.
It's for when you're dealing with a number that you desperately want to continue calling negative, even if it's just as positive, only in the opposite direction.
Please don't burn me for heresy.

;D
You fucking anti-free speech bots.

Sorta

But as you can see

Math is still a model of reality even at it's weirdest

But I bet imaginary numbers as a concept were created way before they could be applied anywhere.

Which proves even more so that math is a *reliable* model of reality

As it has tremendous predictive power

Please tell me when it manages to predict a complex system.
That would be very useful.

What do you mean by complex system?

Reality by definition is a complex system

And math models it well

Why do you even ask when you know what I mean?
Math models simple interactions well. There are too many interactions in a complex system to account for them all.
I seem to remember something about a completely sealed space with as few as three objects interacting with each other being basically unpredictable. Granted, that might have been a load of bullshit.

Three body problem

Not a load of crap

But it seems what math can predict is often misunderstood.

I'm sorry.

For what?

If I misunderstood something.

I really try, but I'm a doctor, not a mathematician ;D

What kind of doctor?

One that just graduated literally yesterday, so not much ;D
