Friday video: The Clock That Changed the World

Thursday, August 20, 2015
Loretta reports:

Years ago, after reading Dava Sobel’s Longitude, my husband and I were very excited to see the actual Harrison chronometers at the Royal Observatory at Greenwich.

This BBC program does a good job of explaining, in half an hour, Harrison’s achievement. It also might make some elements of Patrick O’Brian’s Jack Aubrey series a bit more comprehensible.

You can see one of the clocks we saw at Greenwich here.

Readers who receive our blog via email might see a rectangle, square, or nothing where the video ought to be.  To watch the video, please click on the title to this post.
