Yes Jo, I know what you mean. With some of the sub topics of maths it is very difficult to find 'real life' situations where what is being learnt can actually be used.
I remember when I was being taught the 'J' notation in pure maths. I asked the tutor what use was it, now that we can 'cheat' and take the sq root of a negative number.
The look of disgust I got was amazing and my question was never answered. I'm sure someone one day will tell me a use nut until then it seems it was an exercise just for the sake of it.
Originally posted by PonderableI think that is a wonderful way to not answer a question, but I "feel" that the universe is truly mathematical, not physical.
Mathematics is a philosophical discipline. It works with a set of axoims and Operators and expands from there. Some physical phenomena can be described by mathematical formula.
It is pleasing to find a simple mathematical Expression to explain physical behaviour, but it is not proof that the theoretical Approach is correct.
On the other hand minimizat ...[text shortened]... athematical minimization algorithm if you find a physical example (think dense sphere packings).

Sorry Jo, that was not intentional. Did not read your question thoroughly.
Got to hold hands up and say not quite sure what you mean by the universe being mathmatical and not physical. Would you mind expanding on your thoughts please?
As for expanding on my thoughts, I guess it just seems to me that Mathematics could very well stand on its own without the presence of Physics, but a Physics without Math would be a limited subject. Also, my opinion (as of now) is that the universe is ultimately just a simulation, so the "Physics" that we experience ( our reality ) is actually just the result of mathematics in the simulations programming.
It could even be that we are just androids. Look at what we are attempting to do with artificial intelligence ourselves. Its foreseeable that we will create an android that has enough intellect to question it own existence, when that happens, it should be like looking in the mirror for humanity, however I expect that most will not like what they see.
