A couple of other pieces of evidence to back up the link.
1. I once conversed with a scientist in chitown and he actually saw molecular changes of cryod
metal via an electron microscope. This was decades ago.
2. When working with the Illinois dept of highways, it was well known that when building bridges,
the steel beams were pinged for a month or so to rid of mechanical stresses before assembly,
thus molecular changes had occurred, even without cooling the beams.
cheers and thanks for the link Dave.
