Presentation of iTHEMS outreach at NuFACT conference
iTHEMS is a fantastic environment in which we conduct interdisciplinary research daily. Along with our research activity, a variety of outreach activities have been conducted so far. Tomoya Nagai (Coordinator, iTHEMS) presented this special environment and its outreach activity at the NuFACT 2024 conference. At the conference, a session for Inclusion, Diversity, Equity, Education, and Outreach (IDEEO) was composed. The session itself was organized so that we could visualize diversity in terms of speaker's and convener's properties. It provided us with a good opportunity to know IDEEO-related activities all over the world, which can be a chance to recognize and reconsider the issue around to achieve "good environments for everyone". One special example of the iTHEMS outreach was the "Journalist in residence" program. The uniqueness of the activity caught significant attention from the participants of the conference. Also, "Mathematics Connecting to the World: One S&T poster for Every Household" seemed to be intriguing. Although we had only a limited time for this exhibition and discussion, Nagai's attendance brought the conference a fresh view of the outreach activity as well as the achievements of the interdisciplinary and diverse environments. iTHEMS can be so influential to our community in multiple contexts!

Farewell message from Eiji Inoue
Our colleague Eiji Inoue will move on to a new career as an assistant professor at Kyoto University as of Oct. 1, 2024. We all will miss him and wish him the best of luck in his latest endeavor. Here is a message from Eiji Inoue: I spent three and a half years in iTHEMS as an SPDR on math. I would like to thank the program director and assistants for their mindful support over these three and a half years. I also wish to thank iTHEMS members for discussion on many occasions. These years I spent in iTHEMS were invaluable for me. Among all, the best experience for me was that I could gradually get a feeling on "physics in the real world" not only mathematical structure of physics, from the choice of words physicists use in daily discussion. In these casual discussions, I could also try if my understanding of physics are correct. I also enjoyed playing quantum computers. I think it was impossible to experience without this tolerant environment of iTHEMS; indeed, it just started from a casual conversation with the director. It was the first time I experienced quantum phenomena, especially quantum entanglement, in the real world where I exist. This may sound a little strange, but I feel like I haven't had that feeling of interest in how the real world works in a long time. While I was going through these experiences like a newborn child, as a mathematician, I could finally achieve my original project on Perelman entropy in the last half year during my visits to Cambridge, Montreal and Aarhus. There are still many thigs to do, but this is certainly the foundation of this new theory. One regret is that I could not finish writing a paper on this result while enrolled at iTHEMS. I'll be an assistant professor at Kyoto University (Department of Math) from October. I welcome people from iTHEMS to come to Kyoto and discuss. I will also ask iTHEMS for help. See you again!

Our colleague Yalong CAO will move to the Morningside Center of Mathematics and the Institute of Mathematics at the Chinese Academy of Science in Beijing as an Associate Professor, starting from Jan. 9, 2024. We all wish him success in his new affiliation! Here is a message from Yalong: I am deeply in debt of gratitude to Hatsuda san and all iTHEMS assistants for their generous support over the two and a half years which I spent in iTHEMS. To mathematicians, maybe the most important thing is to have an environment where we can freely develop things that fascinate us, which might not be useful for something else immediately. It is a great fortune to me that iTHEMS provides such an environment. Besides that, I have been enjoying discussing with our lovely members and also wandering in the beautiful Wako campus (especially during Spring and Autumn), which helps to refresh me all the time. I will move to the Chinese Academy of Sciences in Beijing to work and become a visiting scientist of iTHEMS. I hope to come back to visit regularly and continue to enjoy everything here. Everyone is surely very welcome to visit me in Beijing. Let's keep in touch and keep enjoying our life and career.

On Sunday 14th May, Ryosuke Iritani gave a scientific outreach talk at Mathcafe. He focused on spatial biodiversity as a chief topic and how to use mathematics to estimate, and make inferences for, the biodiversity. He explained the measurement of biodiversity from the axiomatic viewpoint, that is, he explained what properties should be satisfied by the quantity that is supposed to measure biodiversity. He then moved on to explaining an application of generating functions to biodiversity measures. He finished his talk by saying that mathematics is not only useful to science but also a life-time fun hobby.

Thomas Hitchcock gave a short talk at Nerd Nite Tokyo on April 21, 2023
On Friday 21st April, Thomas Hitchcock gave a short talk at Nerd Nite Tokyo entitled “Sex Education: reproductive diversity across the tree of life”. There he talked to a general audience about the range of ways that organisms may reproduce, from those organisms that simply make copies of their own genes (asexual reproduction), to those that mix them with others (sexual reproduction), and those that can do both (facultative sex). He discussed the different mechanisms that organisms may use to decide whether to reproduce as a female (producing eggs) or male (producing sperm), and how genes may pass differently to offspring through these two routes, illustrating these ideas with stories about spoonworms, fungus gnats, and rotifers. Finally, he stressed how evolution may work differently in these different reproductive systems, and so the importance of understanding this diversity for guiding our efforts in conservation, agriculture, and medicine.

Also, I got a chance to give a presentation at an event of RIKEN for high school or junior high school students. In my final year, I was chosen as a research member of a program at MSRI and spent four months at Berkeley to communicate with many researchers in my field. I could also invite several researchers to the math seminar and had good opportunities to promote research. I appreciate a good environment in iTHEMS so that I could have these experiences. From this April, I’ll be an assistant professor at Kyoto University. But, I still have several collaborators in iTHEMS, so I’d like to continue discussing with many researchers in iTHEMS as a visiting researcher.
