In this paper (for the moment in Italian language only-sorry) you can find a rare proof of the Gauss Distribution Law, as almost all available books (in the opinion of who is writing) just show it, without giving any demonstration.
Then, here you can also find a description of the 3-sigma rule, very used in the field of technologies.
At last, a peculiarity of the quantum mechanics is here highlighted, where the claim of the equality sign in the Heisenberg indetermination equations leads to a Gaussian wave function, indeed, which reduces to a minimum value the quantum uncertainty situation.
