I saw part of the program and it brought back memories of seeing Harrison's clocks at the Royal Observatory in Greenwich about 3 years ago. I would recommend reading Dava Sobel's book of the same name on which the A&E program is based. She did a *great* job. There is also a larger, more recent edition called "Illustrated Longitude" with hundreds of photos and engravings. The construction work on the larger clocks is flawless, they are works of art as well as engineering. However the most incredible thing was to see the contrast between the first two or three clocks which were around 3-4 cubic feet in size, and the one which finally won him the prize which was like an overgrown pocket watch about 5" in diameter and an inch thick. I always consider that a reminder not to get too hung up on any one approach to a problem. Now back to work on the design of that ocean-going Lehman...

To: PSN-L Mailing List cc: Subject: "Longitude" Hi All I don't know how many of you had the opportunity to see the cable channel "A&E" program called "Longitude". It was a very interesting program about a 16 th century british gent who was trying to develope a accurate clock for ocean vessels, and a 20 th century gent who was trying to restore his forgotten clocks. Time being important for ship location at the time. I had to laugh since it had interesting parallels with seismological instrumentation and it's headaches.
