I interview Seb Falk on "The Light Ages", with my guest J. A. Velasco. We get right to the core of Seb's book and discuss whether people in the middle ages were doing science; we talk about whether people in the middle ages saw themselves as collaborating and competing with each other; and, finally, we look at some fascinating individuals and how they thought about the world, from Robert Grosseteste, Roger Bacon, Petrus Alphonsi, and Ibn al-Haytham.After the interview I spend some time with J unpacking the concept of medieval science and think further about what it means for an activity to be "scientific". For more discussion on "The Light Ages", check out the Forum page on my website: https://www.pleaseexpand.com/forum. I look forward to hearing what you have to say about it!
