The Ottoman History Podcast is featuring episode one of Ventricles, a new podcast about interesting topics in science and technology, past and present. Ventricles is written and produced by OHP contributor Shireen Hamza for the Science, Religion and Culture Program at Harvard Divinity School, and also features past episodes of OHP. Episode one is about the history of timekeeping:

How have humans kept track of time? What technologies have they developed to tell time, and how have they been influenced by religious and scientific cultures? In this episode, Dr. Sara Schechner, a historian of astronomy and an artist who has made sundials herself, speaks about the history of timekeeping, and how timekeeping technologies have shaped people’s sense of time. We also hear from Dr. Avner Wishnitzer about how some people’s sense of time changed with the introduction of modern institutions, creating new “temporal cultures.”
