Earlier today I noticed while reading this academic paper on musical pitch and cochlear impants ...
http://www.phys.unsw.edu.au/~jw/reprints/FearnThesis.pdf
... that it mentions that human hearing is sensitive enough that it is possible for some to detect a sound that only moves the eardrum a distance comparable to the width of a hydrogen atom.
I just wonder if the name of the forum happens to be related to this. Even if not, that's sort of cool, don't you think?
