Pendulum clock ...
that keeps time to within 5/8ths of a second in 100 days –
based on a 250 year old design by John Harrison
. I read
a biography of Harrison last year
(fascinating!). He never built a clock with this design, but he was ridiculed preemptively, toward the end of his life. This is a complete vindication.
