Dr. Chad Orzel is an Associate Professor in the Department of Physics and Astronomy at Union College in Schenectady, NY, where he teaches a wide range of classes, and does research on atomic, molecular, and optical physics. His latest book is A Brief History of Timekeeping: The Science of Marking Time, from Stonehenge to Atomic Clocks.

In this episode, we focus on A Brief History of Timekeeping. Topics include: timekeeping as a human universal; what a clock is; using the “movements” of the Sun; using other stars and the moon; how the cycle of the zodiac got invented; how different calendars got created; the influence of politics and religion on timekeeping; the first clocks; how mechanical clocks work; how global empires and astronomy influenced the evolution of clocks; the development of standardized time zones; the ways by which the physical nature of time differ from the human understanding of it; quantum clocks and their applications; and potential new clocks in the future.

Dr. Eli Alshanetsky is an Assistant Professor of Philosophy at Temple University. Previously, he was an Andrew W. Mellon fellow in the Humanities at Stanford University. He received his PhD in philosophy from NYU. Dr. Alshanetsky's research and teaching interests are at the intersection of the philosophy of mind and language, epistemology, and cognitive science. He is the author of Articulating a Thought.

In this episode, we focus on Articulating a Thought. We start by talking about self-knowledge, how people acquire it, and how it is approached philosophically. We then get into articulation, and the reasoning behind articulating a thought. We also discuss why some thoughts are easy to articulate, while others are very hard, the limits of language, and clarity of thought.

Dr. Jonathan Maynard is a Lecturer in International Politics at King's College London's Department of Political Economy. His research is primarily concerned with the role of ideology in collective political violence, especially in forms of violence against civilians such as genocides, mass atrocities and terrorism. He is the author of Ideology and Mass Killing: The Radicalized Security Politics of Genocides and Deadly Atrocities.

In this episode, we focus on Ideology and Mass Killing. We first define mass killings, and get into explanations presented on the media; what ideology is; how ideologies can influence political behavior; non-ideological explanations; and Dr. Maynard’s neo-ideological explanation. We discuss the “true believers”, and how non-believers can still be influenced; why mass killings take different forms; why they occur; the role played by ideological propaganda and hate speech; if threats are ever real; and if it is possible to predict and prevent mass killings.
