There is a new analysis of the Antikythera mechanism by Michael Wright, formerly of the <st1:PlaceName w:st="on">Science</st1:PlaceName> <st1:PlaceType w:st="on">Museum</st1:PlaceType> in <st1:City w:st="on"><st1:place w:st="on">London</st1:place></st1:City>, now a free-lance mechanician. Using tomography techniques to ‘see’ otherwise hidden information in the surviving relic he has advanced understanding of how it may have worked and what it was likely to have been used for. He has also built a working reconstruction incorporating his findings. A non-technical report appeared in the Economist in 2002 and can be found at <a href="http://www.economist.com/displaystory.cfm?story_id=1337165">http://www.economist.com/displaystory.cfm?story_id=1337165</a>. I am in touch with Michael should anyone want more detail. I believe the work on the Antikythera mechanism is ongoing – it was a few months ago.<o:p></o:p> <o:p> </o:p> Best wishes<o:p></o:p> <div> Doron<o:p></o:p> <o:p> </o:p> Doron D.
