Yes indeed. Our ancestors did some amazing things with the tools they had access to. I found the
book "Finding Longitude" to be fascinating. There are a few books with similar titles. The one I read was written by Dava Sobel, with forward by Neil Armstrong.
The most fascinating thing to me is how he was able to conceive, design, obtain materials, then fabricate a working
marine chronometer that can keep accurate time on board a rolling, pitching, bouncing ship. A major undertaking in the early 1700's.
