We are a new bi-weekly podcast where logic, mathematics, philosophy, and computer science meet. aboutlogic features in-depth conversations with people working in and around the foundations of these subjects. We talk about topics ranging from the foundations of computer science and set theory to critical thinking, puzzles, and what academic life is really like—its motivations, frustrations, and surprises.

Homotopy Type Theory, Logic & Philosophy

"I am convinced that my Begriffsschrift will find successful application wherever particular value is placed on the rigor of proofs, as in the foundations of the differential and integral calculus. It seems to me that it would be even easier to extend the domain of this formal language to geometry. Only a few more symbols would need to be added for the intuitive relations occurring there. In this way, one would obtain a kind of analysis situs."
