SUMMARY:My Mathematical Journey: From Play To Sea!
DESCRIPTION:A SMRI & AMSI Summer School Public Lecture by Jordan Pitt\n\n\n\n\n\n\n\n\n\nEvery time I mention that I’m a mathematician to someone new\, the most popular response is ‘Oh I was TERRIBLE at maths!‘ and a general vibe that I’m an extreme weirdo for not sharing in this feeling. Honestly\, as mathematicians\, we are a bit different but I am going to try and explain why we’re not that weird in this talk. To do this I will provide some stories of my own mathematical journey and why I ended up loving it.  \n\n\n\nIn this AMSI Summer School public lecture\, University of Sydney mathematician Jordan Pitt will talk about his journey in mathematics. This will be a free event targeted to the general public\, including interested school students. More details and registration. \n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\nJordan Pitt\, Associate Dean Indigenous Strategy & Services and School of Mathematics and Statistics\, The University of Sydney\n\n\n\n\n\nDr Jordan Pitt is a descendant of the Birri Gubba people and an applied mathematician. Like most\, his passion for mathematics was sparked by a fantastic high school mathematics teacher. Since that fire ignited\, he has had an academic career completing his undergraduate and PhD at the Australian National University working on numerical methods for tsunami modelling. He now studies the interaction of ocean waves and sea ice to improve climate models at the University of Sydney\, continuing work begun as a post-doctoral researcher at the University of Adelaide. In addition to his academic time\, he has also worked at Geoscience Australia and the Australian Taxation Office on projects from modelling tsunamis to phone call times. \n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\nKey event details\n\n\n\n\n\nDate & time:  \n\n\n\nWednesday 29 January 2025 \n\n\n\nPublic lecture: 5:30 – 6:30 pm \n\n\n\nCanapés & drinks: 6:30 pm – 7:30 pm \n\n\n\n\n\n\n\nCost:  \n\n\n\nThis is a free event \n\n\n\n\n\nLocation: \n\n\n\nSWHB Lecture Theatre 321 \n\n\n\nLevel 3 Susan Wakil Health Building (D18) \n\n\n\nUniversity of Sydney\, Camperdown Campus \n\n\n\n\n\n\n\n\n\n\nRegister for this event

SUMMARY:'Knots\, graphs\, and algebra: a story of surprises' National Science Week Public Lecture by Zsuzsanna Dancso
DESCRIPTION:Knots are everywhere: in the strings of our DNA\, in the structure of super-strong materials\, and in mathematics\, where knots lurk behind all three-dimensional shapes. Graphs model social networks\, transit maps\, neural nets\, and are one of the most basic objects in modern combinatorics. But what does the mathematics of knots have to do with the mathematics of networks?  And how can we use algebra — the science of numbers\, operations\, and structure — to solve mysteries about both? More details and registration. \n\n\n\nThis public lecture is hosted by the Sydney Mathematical Research Institute as part of our program for National Science Week 2025. The talk will be tailored to a general audience and suitable for individuals from Year 10 onward. This is a free event\, however registration is essential. \n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\nZsuzsanna Dancso\, The University of Sydney\n\n\n\n\n\nZsuzsanna Dancso is an Associate Professor of Mathematics at the University of Sydney. In her research she uses algebra and discrete mathematics to study knots and shapes in three and four dimensions. Zsuzsanna’s research is influenced by diverse international experiences and the collaborations she built along the way: born and raised in Hungary\, she completed her PhD at the University of Toronto in Canada\, and worked at multiple top research institutes and universities in North America and Australia\, before joining the University of Sydney in 2017.  \n\n\n\nZsuzsanna values the fresh perspectives that students and young mathematicians bring to the field: indeed\, the project which inspired this lecture included two University of Sydney students\, in addition to an international collaborator. Outside of mathematics\, Zsuzsanna enjoys dance\, musical theatre\, and feeding people. \n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\nKey event details\n\n\n\n\n\nDate & time:  \n\n\n\nFriday 15 August 2025 \n\n\n\nPublic lecture: 5:30 – 6:30 pm \n\n\n\nCanapés & drinks: 6:30 pm – 7:30 pm \n\n\n\n\n\n\n\nCost:  \n\n\n\nThis is a free event \n\n\n\n\n\nLocation: \n\n\n\nLecture Theatre 321\, Susan Wakil Health Building\, University of Sydney\, Camperdown Campus \n\n\n\n\n\n\nRegister for this event

SUMMARY:Science at the Museum
DESCRIPTION:National Science Week 2025: Decoding the Universe – Exploring the unknown with nature’s hidden language\n\n\n\n\n\nSaturday August 16 from 12 – 4pmSunday August 17 from 12 – 4 pm \n\n\n\nTo mark National Science Week\, the Sydney Mathematical Research Institute (SMRI) and the Chau Chak Wing Museum (CCWM) are collaborating again on a stimulating weekend for the whole family in the museum at the University of Sydney! \n\n\n\nThis year’s theme of National Science Week is ‘Decoding the Universe – Exploring the unknown with nature’s hidden language’. Over the weekend\, we will be delving into the hidden languages of nature – how do mathematics and sciences describe the world around us and allow us to push the boundaries of knowledge? \n\n\n\nJoined by the Sydney Institute for Astronomy\, we will be celebrating with a variety of activities and floor talks\, culminating in an interdisciplinary panel exploring the theme. To explore how the rules of nature govern our world\, join us to participate in Briony Barr’s Klein Bottle Experiment. This is a large-scale\, collaborative artwork which uses rule-based play to visualise how participants interact with one another and our environment\, using the hidden languages of the Universe! \n\n\n\n\n\n\n			\n				\n			\n		\n\n\n\n\n\n\n\n\n\n\n\nExpert floor talks\n\n\n\nSaturday 16th August\n\n\n\n12:15 – 12:45 pm  2\,000 years of twinkling\n\n\n\nEmily Kerrison\, Sydney Institute for Astrophysics (SIfA)\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\nTwinkle twinkle little star\, we know exactly what you are. Humans have been studying the stars for as long as we have looked up at thenight sky. But why do they twinkle? Do other objects in the night sky twinkle too? Come on a journey from Ancient Greece all the way to modern day Australia\, as we follow a story of discovery about why things twinkle at night\, and how this twinkling can be used to understand the world around us. \n\n\n\nEmily is a PhD student in Astrophysics at the University of Sydney\, with a background in both science and Classical literature. She is interested inpiecing together the stories of supermassive black holes from datasets taken all around the world\, including right here in Australia. When I’m notlooking at black holes\, I like thinking about how the way we do science has changed over the course of decades\, centuries\, and millennia. \n\n\n\n\n\n\n\n1  – 1:30 pm Introducing Biodesign: applying science outside the lab\n\n\n\nPhillip Gough\, Design Lab and School of Life and Environmental Sciences\n\n\n\n\n\n\n\nIn the future\, we will need to develop a circular economy. One that takes waste and turns it into something new\, that has some value. For designers it’s important to select the best materials for circularity. Instead of materials that will last for centuries\, materials should be able to be broken recycled or returned to the natural cycles. So why not work with Earth’s natural material recycling system\, fungi!? This talk introduces biodesign\, which applies the understanding of science to design challenges\, and uses living organisms as partners to create a better\, more sustainable\, world. \n\n\n\n\n\n\n\n1:45 – 2:15 pm How animal behavior can shape the environment in unexpected ways\n\n\n\nAmelia Meier\, Thriving Oceans Research Hub \n\n\n\n\n\n\n\nThis talk will explore how animal behavior can have large-scale impacts on the environment and how it can be studied using satellites and big data\, with examples from Amelia’s research on species such as elephants and sharks. Understanding such behaviors helps conservationists better protect wildlife and their habitats. \n\n\n\n\n\n\n\n2:30 – 3 pm Building huge radio telescopes (and finding tiny stars)\n\n\n\nKovi Rose\, Sydney Institute for Astrophysics (SIfA) \n\n\n\n\n\n\n\nWe have entered the age of big data in astrophysics and radio astronomy is no exception. The Australian SKA Pathfinder (ASKAP) conductswide-field radio surveys of the southern skies. With millions of radio-bright sources in the survey regions we are using new polarisationfiltering and positional cross-matching\, as well as more traditionalvariability metrics\, to identify interesting astronomical transients. Fromstellar radio emission to late-time supernova re-brightening\, I will speakabout some of the different objects we are finding with ASKAP\, including the detection of periodic bursts from an ultracool brown dwarf star. \n\n\n\nKovi is an astrophysics PhD candidate and LSST Data Science Fellow at the University of Sydney who uses radio telescopes to study distant starsthat go snap\, crackle\, and pop. Outside of research\, he spends most of his time communicating science through his writing\, podcasting\, and memes. \n\n\n\n\n\n\n\n3:15 – 3:45 pm Journey to the beginning of the Universe\n\n\n\nCiaran O’Hare\, Sydney Institute for Astrophysics (SIfA) \n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\nWhere did everything we see around us come from? To figure this out we need to go back 13.8 billion years to when the primordial ingredients of our Universe were first forged. I will tell you what we do and do not yet understand about the Big Bang and how the fundamental constituents of nature were created. \n\n\n\n\n\n\n\nSunday 17th August\n\n\n\n12:15 – 12:45 pm Visiting poems as if they were cities (and searching for an optimal route)\n\n\n\nKaty Gero\, School of Computer Science \n\n\n\n\n\n\n\nThe Anxiety of Conception is a poetry book in which each copy of the book represents a unique tour through the poet’s memories. Written in the months leading up to and following the birth of the poet’s child\, poems are ordered (and reordered) according to a “traveling salesman” algorithm. This talk will present the concept of the book and the maths used to order the poems. \n\n\n\n\nKaty Ilonka Gero is a writer and human-computer interaction researcher. Her writing and poems have been published in Catapult\, The HTML Review\, Wired\, and more. With Kyle Booten\, she is the co-founder of Ensemble Park\, a journal that collects literary experiments in human-computer co-writing. Her computer science research spans computational creativity\, AI ethics\, and the psychological impact of AI writing assistance. She is currently a Lecturer at the University of Sydney in the School of Computer Science. \n\n\n\n\n\n\n\n\n12:50 – 1:10 pm Explainer: Drawing on Complexity\n\n\n\nBriony Barr \n\n\n\n\n\n\n\nOver the weekend\, visitors will contribute to a collaborative artwork by Brisbane-based artist Briony Barr using paper and washi tape. This body of work\, ‘Drawing on Complexity’ uses rule-based drawing and social dynamics to model complex adaptive systems\, and has been designed in collaboration with physicist Andrew Melatos. \n\n\n\n\n\n\n\n1:15 – 1:45 pm Finding radio stars in a haystack of black holes\n\n\n\nLaura Driessen\, Sydney Institute for Astrophysics (SIfA) \n\n\n\n\n\n\n\nDid you know that black holes can photobomb stars? Hear about how we’ve more than doubled the known number of radio stars using Australia’s ASKAP telescope. Stars might seem easy to find\, but it’s a lot trickier with black holes everywhere! \n\n\n\nLaura Driessen is a radio astronomer and science communicator.

SUMMARY:'Is Dijkstra's Algorithm Optimal?' - A Basser-SMRI Joint Seminar by Robert Tarjan
DESCRIPTION:Dijkstra’s algorithm is a classic algorithm for doing route planning. Given a starting location it finds shortest paths from to all other reachable locations using the greedy method. Not only does it find shortest paths\, it finds these in increasing order by length. A natural question is whether this algorithm is best possible. The answer depends on exactly how one poses the question. The talk will cover recent work by the speaker and his colleagues that gives the answer “yes” and briefly examine work by others that gives the answer “no.” \n\n\n\nJoin us for the first Basser-SMRI Joint Seminar\, to be given by Robert Tarjan (Princeton). Basser Seminars highlight the best of computer science research. Feel free to distribute to others that may be interested. After the seminar\, please join us for a special afternoon tea\, held at 3 pm. \n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\nRobert Tarjan\, Princeton University\n\n\n\n\n\nRobert Tarjan is the James S. McDonnell Distinguished University Professor of Computer Science at Princeton University. He has held academic positions at Cornell\, Berkeley\, Stanford\, and NYU\, and industrial research positions at Bell Labs\, NEC\, HP\, Microsoft\, and Intertrust Technologies. He has invented or co-invented many of the most efficient known data structures and graph algorithms. He was awarded the first Nevanlinna Prize from the International Mathematical Union in 1982 for “for outstanding contributions to mathematical aspects of information science\,” the Turing Award in 1986 with John Hopcroft for “fundamental achievements in the design and analysis of algorithms and data structures\,” and the Paris Kanellakis Award in Theory and Practice in 1999 with Daniel Sleator for the invention of splay trees.

SUMMARY:'Pure mathematics as applied physics' - A special International Day of Mathematics Colloquium (2/2) by Tadashi Tokieda
DESCRIPTION:Humans tend to be better at physics than at mathematics.  When an apple falls from a tree\, there are more people who can catch it — they sense physically how the apple moves — than people who can compute its trajectory from a differential equation.  Applying physical ideas to discover and explain mathematical results is therefore natural\, even if it has seldom been tried in the history of science.  The exceptions include Archimedes\, some old Russian sources\, a recent book of Mark Levi’s\, as well as articles and lectures by yours truly.  Many examples will be presented. \n\n\n\nThis event is part of a series of 2 colloquia for International Day of Mathematics (Colloquium 1: Irrational ways of manufacturing numbers).
