I'm not basing my statement on theory, I'm stating an empirical
observation. Remember my ice example? This result may be simply
expressed in a theory of sound transmission in solids, but I am
unaware of it. I have never subscribed to the dictum "Never trust
an experimental result until it has been confirmed by theory".
