Yesterday, the blogosphere (see Daring Fireball, kottke.org, and even Slashdot) was ripe with links to a New York Times or a Guardian UK article regarding the Antikythera mechanism. The device was discovered in 1902 and was known to be an mechanical calculator for astronomical events. New research presented at an international conference and as documented in the November 30th issue of Nature appears to be the catalyst for the torrent of articles appearing yesterday and today. New imaging has revealed more of the complexity, models the device, and appears to have solved which events the device tracks. Why these events were tracked remains a mystery.
Edit - even MSNBC and CNN are now in on the act.
