In 2001, Stanford mathematician Dr Keith Devlin, also known as ‘The Math Guy’ on NPR’s Weekend Edition, set out to research the life and legacy of the thirteenth century mathematician Leonardo of Pisa, popularly known as Fibonacci. Leonardo introduced the Hindu-Arabic numeral system and arithmetic to the Western world, and thereby helped start a global, social and economic revolution. Devlin recounted Leonardo's story in a 2011 book titled The Man of Numbers: Fibonacci’s Arithmetic Revolution. In a simultaneously published companion e-book, Leonardo and Steve: The Young Genius Who Beat Apple to Market by 800 Years, he drew remarkable parallels between the careers of Leonardo and Apple’s Steve Jobs. His new book, Finding Fibonacci: The Quest to Rediscover the Forgotten Mathematical Genius Who Changed the World is a first-hand account of his experiences in uncovering the story, reconstructed from his project diary and notes, together with stories of three other contemporary scholars who were also motivated to find out about the long-forgotten medieval mathematician who did so much create the world we live in. This talk was held as part of the Sydney Ideas program on 3 October: http://sydney.edu.au/sydney_ideas/lectures/2017/keith_devlin.shtml

There are many accounts of consumer directed care (CDC )in England. Some focus on its ambitions, some on its achievements, some on its problems and some on its experiences. A series of 'myths' is being constructed around all four of these dimensions. Professor Jill Manthorpe from the Social Care Workforce Research Unit at King's College London, who has undertaken several studies of this subject over the past decade in both England and Scotland, tackles some of these myths and sets out a few mysteries for participants to solve.

Is home a closed-off and self-sufficient place, or can it be reimagined to be where we find our connections to others and the world? By exploring home in relation to the figure of the stranger and public space, as well as with a focus on practices of dwelling and materialities, the authors of 'Reimagining Home in the 21st Century' demonstrate that thinking differently about home advances our understanding of belonging as a social process in which we are all implicated.

‘Health hacks’ telling us how to stay young in mind and body are everywhere these days, but are they true? Can we trust their advice? In this health forum, our expert panel will highlight helpful insights that are changing people’s lives for the better, and teach us all how to best look after our minds and bodies as we age.

Paul Farrell (Buzzfeed Australia), Benedetta Brevini (Senior Lecturer in Communication and Media), Julie Posetti (journalist and academic) and Gabor Szathmari (CryptoAustralia co-founder) discuss the extent of data collection revealed by Edward Snowden’s 2013 intelligence leaks and the sharp acceleration of new national security and data retention legislation in Australia.

'Gatekeeping' continues to be a rousing and provocative word with regard to Indigenous and non-Indigenous relations. Gatekeeping pertains to the various forms of apartheid in Australia, some of which still apply, if in a veiled and insidious way. But the term is also relevant to Aboriginal communities themselves, in which differing degrees of 'whiteness' and 'blackness' are consigned different values of entitlement and belonging. It is a taxonomy that tends to elide the deeper and more urgent issues that Indigenous cultures, in Australia and elsewhere, currently face. In the spirit of launching the journal co-founded by Professor Jakelin Troy and Dr Adam Geczy (who are the editors, with Lorena Sekwan Fontaine), of ab-Original (Penn State University Press), 'gatekeeping' is used as a relevant and ironic term for a journal whose key mission is to examine global indigenous cultures and their diverse transnational and pan-racial contexts. Joining Prof Jakelin Troy and Dr Adam Geczy in this discussion are Blak Douglas (aka Adam Hill), an artist, musician and social activist and Dr Mick Adams, Senior Research Fellow Australian Indigenous Health, at Edith Cowan University, WA. This forum was held as part of the Sydney Ideas program on 14 September, 2017: http://sydney.edu.au/sydney_ideas/lectures/2017/gatekeeping_ab-0riginal_launch_forum.shtml

Professor Ayhan Aktar from Istanbul Bilgi University discusses the turning points in the Turkish process of rewriting the history of the Gallipoli Campaign since the 1930s.

For many years now, anthropologists and urban scholars alike have identified ‘gentrification’ as a process of class conflict in which poorer people get pushed to the margins of urban life in the name of ‘urban renewal'. Using examples from Thailand, China, Greece, and Italy, Professor Michael Herzfeld argues that these short-sighted policies are creating an increasingly disenfranchised and resentful under-class.

Join visiting philosophers Jonathan Tallant (University of Nottingham, UK) and Elay Shech (Auburn University, USA) in a conversation with Associate Professor Kristie Miller from the University of Sydney, as they discuss what implications contemporary physics has for our understanding of time, and how philosophers are engaging with cutting-edge physical theories in their attempts to understand time.
