Yes, I was referring to the golden ratio. And other things: proportions, measurements, calculations, material sciences, research and development of materials and techniques...
The universe is vast and grand and complex—and yet it also fits together so seamlessly, so neatly, a man can't help but wonder if there is something out there that can explain everything. And if such a theory can be found, it will likely be written in the language of maths.
I was going to say in sound... but I'm guessing that's maths as well somehow! :)
