This is the first episode of another small spinoff of It's Not Just Numbers, were we discuss with researchers working on mathematical topics in different disciplines and departments.

In this episode, we talk to Jorge Perez (Computer Science department) and Davide Grossi (Artificial Intelligence department). As you will hear, both of them use a lot of mathematics in their research and work on topics that also have very theoretical angles.

Throughout the episode, we discuss intedisciplinary collaborations, reaching outside one’s own line of research and the key role ofof asking questions to facilitate the exchange. We also explore if and how common stereotypes on academics change in Computer Science and Artificial Intelligence from a societal point of view.

What is a proof? And what is a proof assistant? Isn't writing proofs what mathematicians are supposed to do themselves? In this episode, Sander Dahmen and Jim Portegies, will help us explore these questions and introduce us to the fascinating world of fomralizing mathematics. Of course, after taking our time to get to know them better.

You have studied mathematics... now what? In this episode we talk to Sven Bootsma, Max Lein and Oscar Koster about the possibilities for mathematicians that don't pursue a career in academia.

After getting to know them, with their motivations to study math and their hobbies (mainly sports!), we focus on theie career in industry after having studied mathematics . In this long episode we span across many themes and discuss how a mathematician can find a job in industry, what the differences are with working in academia and how students could go about choosing a career after their studies.

This episode is packed with insights and interesting suggestions but only scratches the surface of this interesting discussion, leaving many additional question unanswered waiting for a future afterMath2 episode!

So let us invite you to join us in a future recording: if you are a mathematician and you are not working as an academic, especially if your job is different from the ones that we heard about in this episode, please send us a mail!

And if there is anything that you would like to discuss in the next episodes, let us know in the comments (or sending us a message).
