 All right, so I'm here with David Roberts from the University of Minnesota Morris, and he's visiting ICDP in which capacity? I'm here for two weeks as a Simon's visiting professor. And what is that? Well, that means that prior to coming here. I was at a workshop at Oberwollfauk, a math institute in Germany, and sort of attached to that there's a program supported by the Simons Foundation where American scientists get to, on top of the visit to Oberwollfauk, collaborate with people at European universities. So in this case, I'm coming to ICDP. I'm here at ICDP. And you came here to work on a project, you said? Yes, I'm working on a project that are titled Hypergeometric Motives, and my collaborators are Fernando Rodriguez Villegas and Mark Boone's here at ICDP and Mark Watkins, who's from University of Sydney. And this project has been going for some time here? Yes, it's been going for quite a while. I think one of the things slowing it down is almost a language issue. So Mark from Sydney programs in Magna and Fernando here programs in a different software called GP. And my area of great fluency is Mathematica, so we have to make all these things merge. That's one of the issues. And would you be able to describe in a couple of sentences? What this is about? Well, sort of. So Hypergeometric Motives, to me, certainly is a very interesting subject. It has classical roots, but in classical meaning, going back to the 1800s. But to really understand things properly, you need a very modern perspective. And it's an interesting blend of algebraic geometry and number theory. And our particular approach, which is maybe the novelty of what we're doing is is very heavy on the computational side. So we're trying to see these things as explicitly as possible, which to us is a fun and important thing. But it's maybe not quite so traditional in mathematics. Very good. And what do you expect this book to come out? Oh, I think I will decline to make a prediction. We made this is the end of my two weeks here and the three of us made quite a lot of progress. And this is not your first visit to ICTP. No, I was actually trying to take how many times I've been here. I think it's four, perhaps it's five. I've enjoyed each visit. Any thoughts on this is a different kind of institute. So what's your your take on on on it? Well, so I've seen it in the summer and the fall. And I think I would like to see it in the spring and the winter. My colleague Mark says it's different, but still quite nice in the winter. Very good. So thanks, David. And till next time.
