So i guess that by that you are saying that math is so developed it can even describe the formation of the whole universe because you watched a video of a computer model?.

And andytoshi said "I'm not sure what you mean by "math hasn't got to the stage where it can describe complex systems". I have a math degree and several published papers in mathematics and I can't for the life of me square this claim with actual work in the field. "

So neither of you are aware of some fundamental unsolved maths problems which appear quite mundane, like a complete model for how turbulence works: "In particular, solutions of the Navier–Stokes equations often include turbulence, which remains one of the greatest unsolved problems in physics, despite its immense importance in science and engineering."

or until a few years ago we didn't even have a model for how sound waves actually work: http://en.wikipedia.org/wiki/Nonlinear_acoustics

both complex systems....math not work yet (ok non-linear acoustics was just found...)

And my point that it is more secure to remove information from a system than to keep it in the system encoded, which means you don't need cryptography for all parts of a cryptocurrency, was avoided.
