comment How much information about the scale of a waterfall can be obtained from its sound?
Interesting question. Surely there is a characteristic for the speed of collision of water with the flat ground/water below. I am guessing that the spectrum of droplet sizes grows with height, adding a 'big squish' sound for high falls. This could be tested in a lab.

I agree, yes, the experimental point of view is also interesting.

comment Reasons for violation of universality in statistical mechanics
The term 'universality' relates to solvable systems with the parameters belonging to a specific class. Anyway there is no generic one size fits all answer to the breaking of universality - because in principle we could solve a complicated system one day and discover new universality classes. The concept of universality hinges only on the independence of the parameters from all physical details of the system. Yes it is more general than renormalization itself. And we cannot definitively say that universality is 'broken' just because we do not recognize the features of a given transition.
