Kewl Clocks

A video Harvard recently posted of their scientific instrument collection. The one I particularly liked was the clock around the 3:30 spot that was used to synchronize local clocks at train stations, for example, and talks about why that was important (hint: there was often only 1 track btwn stations).

What we won't come up with to keep ourselves entertained/informed.

Here's what was in the HURA* email about the collection: Harvard University has been acquiring scientific instruments for teaching and research since 1672. The Collection of Historical Scientific Instruments was established in 1948 to preserve these instruments as a resource for teaching and research in the history of science and technology. Many of the objects are stunning examples of craftsmanship and art.
