  Was that meant as a joke or am I completely missing the point here? Mathematics provides plenty of tools to work with infinities. In plural, because there are quite literally infinitely many different infinities, which we know thanks to maths.

  Couldnt it be modeled as electrical activity inside specific areas of the brain under certajn circumstances?

It's the same as: There are more real numbers than you can write down. (Everything you can write down using symbols can only be enumeratable many (you can enumerate all symbol combinations starting with single symbols), but there are uncountable many real numbers) So now you say: Could you give me an example of such a real number that we can not write down? Answer: No such example can be given because even e or pi or any other real number constructed by an equation is given by just inventing new (countable many) symbols (like π) or by writing down an algorithm which consists of countable many symbols. So to answer your question: There could be problems that can not be explained by math but in the same way you might not even be able express/name/describe the problem.

  If framed as a logical equation, wouldnt math explain or have an answer? Sure, i may not write an answer, when thinking from an algebraic perspective, but i sure can answer it from a logical or sets perspective. Perhaps the answer is an empty set?

    I am not sure I understand what you are saying. If you are speaking of equations you are speaking of symbols right? (∧,∨,¬,...) Whose combinations are only countable many. The answert to what is the empty set?

      >Could you give me an example of such a real number that we can not write down? Thst this is a question without any answer can be quantified as a logical equation. The question might not have an answer that is a number, but has a superseding answer thst it is not logically consistent.

      Well the answer to: > Could you give me an example of such a real number that we can not write down? Is clearly: No, I can not. But the answer to the question "Are there real numbers that can not be written down in _any_ way" is clearly: yes. If the question is understood as "Is the set of reals bigger than the set of naturals?". So there are cases in which the answer to "can you give me x?" != "is there an x?". So back to you original question: > > not everything can be explained with math > Can you give me any examples? I'm curious. I guess nobody might be able to give you any examples but they could still exist.

  The same is true for functions. There exist many more functions (eg ℕ→ℕ) than you can write down because the powerset of ℕ is bigger than ℕ. So it could be that there could be a physical law that the property X of an object is a function of property Y but that function is one which we could not even see as a function because we can not encode it in symbols and probably our brain would not even recognize it as function at all (?)

I think this is an example: Math works well for electronic circuits, but it doesn't work well for psychology. Maybe coincidentally, we can predict circuits but not people.

I'm surprised by the downvoting on this thread. Kumarvr asked for examples of things math doesn't explain. Simple examples of things math doesn't (at this time) explain (e.g. psychology; dreams) were downvoted. Why? There's no way to know why. Just downvotes. Maybe someone thinks math explains physics, which explains [...], which explains dreams. Maybe that's not it at all. Who knows? I can only speak for myself here, but silly downvotes are the primary reason I'm disengaged with this otherwise really great site.
