SUMMARY:'Irrational ways of manufacturing numbers' - A special International Day of Mathematics Colloquium (1/2) by Tadashi Tokieda
DESCRIPTION:This is meant to be light mathematical entertainment\, exploring simple yet unusual phenomena involving rational\, irrational\, transcendental numbers.  We will also glean a few open problems. \n\n\n\nThis event is part of a series of 2 colloquia for International Day of Mathematics (Colloquium 2: Pure mathematics as applied physics). For catering purposes\, we would appreciate your registration if you intend to attend one or both events. \n\n\n\n\nRegistration\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\nTadashi Tokieda\, Stanford University\n\n\n\n\n\nTadashi Tokieda is a professor of mathematics at Stanford.  He grew up in Japan as a painter\, became a classical philologist (not to be confused with philosopher) in France\, worked a little as a plumber\, before earning a PhD in pure mathematics from Princeton then practicing applied mathematics throughout the world.  Active in outreach\, especially via the YouTube channel Numberphile and the African Institute for Mathematical Sciences\, he gave public lectures at the quadrennial International Congress of Mathematicians 2018\, 2022\, and is slated to speak again at the ICM 2026. \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 13 March 2026 \n\n\n\nSeminar: 12 — 1 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\nCarslaw 175 \n\n\n\nUniversity of Sydney\, Camperdown Campus

SUMMARY:'A world from a sheet of paper' International Day of Mathematics Public Lecture by Tadashi Tokieda
DESCRIPTION:Starting from just a sheet of paper\, by folding\, stacking\, crumpling\, tearing\, we shall explore a rich variety of phenomena\, from magic tricks and geometry through elasticity and the traditional Japanese art of origami to medical devices and ‘h-principle’. Much of the lecture consists of table-top demos.  \n\n\n\nThis public lecture is hosted by the Sydney Mathematical Research Institute as part of our program for International Day of Mathematics/ Pi Day. 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\nTadashi Tokieda\, Stanford University \n\n\n\n\n\n\n\nTadashi Tokieda is a professor of mathematics at Stanford.  He grew up as a painter in Japan\, became a classical philologist (not to be confused with philosopher) and worked a little as a plumber in France and\, after PhD in pure mathematics from Princeton\, has been an applied mathematician around the world.  He is active in outreach e.g. via the African Institute for Mathematical Sciences and the YouTube channel Numberphile; he gave public lectures at ICM 2018 and 2022\, and is slated to speak again at ICM 2026. \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 13 March 2026 \n\n\n\nPublic lecture: 5:30 – 6:30 pm \n\n\n\nCanapés & drinks: 6:30 pm 8 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
