# SCGP News, Volume VII

The Simons Center for Geometry and Physics is pleased to announce the latest issue of SCGP News, a biannual publication which reflects the Center’s mission, scientific and cultural events. In this issue the Founding Director, John Morgan, recounts the Center’s early days, the power of transversality, and more. SCGP Professor Simon Donaldson contributes an elegant mathematical vignette. 2014 Fields Medal laureate Martin Hairer, the sole organizer of the Simons Center workshop on Stochastic Partial Differential Equations, shares his opinion on the funding of mathematics, talks about his interest in sound and the creation of his Amadeus software.  We encourage you to read about the latest exciting edition of the Della Pietra Lecture Series featuring Tadashi Tokieda and watch videos of his engaging talks. In this issue we celebrate Professor of Mathematics Tony Phillips’ life at Stony Brook University; listen to his story of the golden days of Stony Brook University Mathematics, learn about his interest in labyrinths, tides, and his use of Hairer’s Amadeus software for recording birds songs. The issue also delves into the pioneering research of the Center’s programs and workshops, Art Program events, offers a new puzzle by Alexander Kirillov, as well as fascinating cooking tips from the SCGP Café’s Chef Paolo Fontana and … from Martin Hairer!

## Two And Two Make Four. By Simon Donaldson

By Simon Donaldson If we have four objects—say A, B, C, D—there are just three ways of dividing them into pairs: (AB)(CD) (AC)(BD) (AD)(BC). The salient property is that 3 is less than 4. This simple fact expresses something special about the number 4. For example if we take 6 objects there are 10 ways to divide […]

## Reflections On How This All Came About. Conversation with John Morgan

Interview by Maria Shtilmark How did you become the Director of the SCGP? I was quite happy being a math professor at ­Columbia. I had heard about the Simons Center, mainly as Mike Douglas was ‘on the market’ and, together with the Physics department at Columbia, we made him an offer. It looked like we […]

## I JUST LIKE PINK FLOYD. Conversation with Martin Hairer, Regius Professor of Mathematics at the Mathematics Department of the University of Warwick

Interview by Maria Shtilmark Pleasure to welcome you at the Simons Center. You were able to not only come to the Center, but to be a sole organizer of the workshop on Stochastic Partial Differential Equations. What were the workshop’s highlights? We naturally focused on recent developments. I tried to invite participants from different directions, […]
