Each week, Ventricles introduces an interesting topic about science and technology, from the past, the present and sometimes (how we imagine) the future. Featuring interviews with scholars working at the intersection of science, religion and culture, Ventricles explores the many ways that people know and have known the world.

Ventricles is a new podcast written and produced by Shireen Hamza for the Science, Religion and Culture Program at Harvard Divinity School. We'd love to hear your thoughts -- write to us at
