I said that he was trying; not that he was successful. I do keep hoping that someone will come up with a scheme to extract sound "recordings" of some type from ancient times -- ditto with "photographs". At 12:39 PM 10/31/03 -0800, Marc LeBrun wrote:

=Henry Baker <hbaker1@pipeline.com> Some interesting facts: [...] There's even a scientist who is trying to extract ancient sounds from clay pots that were made on a potter's wheel. His theory is that the sounds modulated the surface of the clay during spinning, so it may be possible to play them back like a record.
Not to detract from the other interesting facts you cite, but I find this very dubious, though it was featured recently in the pop-sci media. Forgive this rant, but I'm finding there's more of this kind of pseudoscience about lately (though more typically in support of sociopolitical agendas).
