Dr. Jessica Warren, lecturer of physics and astronomy at Indiana University Northwest, is active in science outreach and education. She is also passionate about sundials. For Indiana University outreach shecreated a video "The Garden Sundial - Much More than an Ornament" that presents a brief history of the sundial, how they work, and where to get one or make one.
You can watch the video on YouTube at https://www.youtube.com/watch?v=K10nPV69Q1A. It is also part of the North American Sundial Society library of videos, found on this website at https://sundials.org/videos/making-and-using-sundials.html where NASS has a collection of videos on sundials, timekeeping, and interviews with sundialists on how they make sundials.
At the end of her presentation, Dr. Warren provides a list of reference material about sundials. Her entire video including references is available as a PDF and is available for download at the bottom of this article. Additional references and sundial topics are available on the NASS sundial links page: https://sundials.org/dial-links/general-sundial-links.html. Read more about the fascinating world of sundials.
