  Jak Kelly Award winner for 2017

Wednesday 6 December 2017
Union, University and Schools Club, 25 Bent Street, Sydney

The Jak Kelly Award was created in honour of Professor Jak Kelly (1928 - 2012), who was Head of Physics at University of NSW from 1985 to 1989, was made an Honorary Professor of University of Sydney in 2004, and was President of the Royal Society of NSW in 2005 and 2006. Its purpose is to encourage excellence in postgraduate research in physics. It is supported by the Royal Society of NSW and the Australian Institute of Physics, NSW branch. The winner was selected from a short list of candidates who made presentations at a recent joint meeting at UNSW of the Australian Institute of Physics NSW Branch, the Royal Australian Chemical Institute and the Royal Society of NSW.

The Jak Kelly Award was presented to Moritz Merklein by John Hardie FRSN, a past president of the Society.

In his lecture Moritz presented a memory for optical data that is based on sound waves and has the potential to revolutionize next-generation computer chips. Today, mediating heat is one of the most significant challenges in computing, particularly in large data centres. Photonic interconnects can solve this challenge, connecting different processing units without generating heat, while offering a broad bandwidth and data throughput. However, the vast speed of light is imposing new challenges on these integrated circuits that harness light as information carriers, requiring an optical memory to slow down information for buffering, synchronization, re-routing and further processing of the data. Controlling the speed of light is challenging, and so far no method has been developed that reaches the required bandwidth, the fractional delay, and is compatible with complex optical data encoding schemes, and least of all can be integrated into a photonic circuit. Transferring the optical data to sound waves can provide a powerful solution to this challenge, enabling to slow down of the flow of information on the chip. It is like storing a flash of lightning inside thunder.

Moritz Merklein received his Physics Diplom from the University of Konstanz, Germany in 2012. His thesis dealt with the fabrication of silicon nitride nanostructures and the characterisation of their mechanical modes using ultrafast pump-probe spectroscopy. Moritz joined the stimulated Brillouin scattering group in the Department of Physics at The University of Sydney as a PhD student in 2014. During his PhD, he has made significant contributions to the field of stimulated Brillouin scattering, which describes the interaction between sound and light waves. His research supervisors are Professor Benjamin Eggleton and Dr. Birgit Stiller. During his PhD studies, he served as the president of the University of Sydney optics student chapter and has engaged in many outreach activities.

   “Women artists: barriers and frustrations”

   Pamela Griffith

   Artist, designer, master printer and author

Wednesday 1 November 2017
Union, University and Schools Club, 25 Bent Street, Sydney

Pamela Griffith shared some of the joys and challenges she has encountered as a female artist. Her talk was illustrated by images of her work and some works of women artists of the past. 

Females are often the model and rarely the artist, and this has led to some offensive and exploitative works around the female subject matter that have coloured the way people see women in art. It has also affected how women see themselves. Pamela speculated on where historically female artists acquired their training and how they were assisted to have an art career by their families and patrons. She showed how they overcame social difficulties and barriers to making art. She tracks what happened to their art.

The presentation attempted to explain art history’s omission of almost all women from its canon. There is an ongoing resistance of art museums to buying art made by women. Few women have solo shows before they are dead. Most women who go to art schools and make up the majority never have their work displayed in any big museums or bought for major collections. Does this mean that women at art schools are wasting their time?

Pamela Griffith is an an artist, designer, master printer and author. She has had over 100 one-woman exhibitions in over 30 galleries. Her work is included in National, State and Regional Gallery collections across Australia and in major corporate and private collections in Australia, Europe, USA and Asia. Major commissions include Bicentennial and Macquarie toiles; Mary McKillop toile; portraits of distinguished Australians such as Dame Joan Sutherland, Richard Bonynge, Sir William Dean, Cardinal George Pell, Professor Marie Bashir and Elena Kats-Chernin; numerous etching editions for corporations including Qantas, Comalco, Department of Prime Minister and Cabinet. She is also the author of over 80 articles and two books on art.

  “The freedom to use your own intelligence:
  the Enlightenment and the growth of the
  Australian nation”

  Emeritus Professor Robert Clancy AM FRSN
  School of Biomedical Sciences and Pharmacy
  University of Newcastle

Monday 6 November 2017
Mitchell Theatre, Sydney Mechanics’ School of Arts, 280 Pitt St., Sydney

In this second lecture of the Enlightenment series Emeritus Professor Robert Clancy asks us to consider the fact that in little more than a century, a gaol established in Sydney Cove with 1000 souls joined the international stage as an independent Federated nation of in excess of three million – an unprecedented event in the history of man! This presentation explores the theme that the convict settlement was the ‘perfect storm’ to test the idea that the Enlightenment with its roots in late Middle Age Europe, and finding its expression in the Laws of Newton and the logic of Locke, created a confidence and capacity for humanity to achieve a new potential. Professor Clancy will first discuss the influence of the dominant contemporary ideas in science as introduced by James Cook and Joseph Banks and how this plays out in a young Australia in its impact on patterns of scientific development. Second, the self-belief and ‘have a go’ mentality reflected John Locke’s optimistic view of men and women forced to face and control extraordinary challenges not just to survive, but to create a new and independent society, based on science and the goodness of man. The question today is “have we lost that spirit of the Enlightenment to reactive conservatism?”

Emeritus Professor Robert Clancy has had a distinguished career as a clinical immunologist. He was awarded an AM for his services to immunology, as well as to cartography through his collection of early maps of Australia. He was Foundation Chair of Pathology at the University of Newcastle and the Director of the Hunter Immunology Unit.

Professor Clancy is a expert on medical history, with a particular focus on the history of infectious disease and immunology, including the impact of plague. He led the ASAEurope: the History of Medicine and Pharmacy tour in 2006, 2011, 2013 and 2015 and has developed a ‘History of Medicine’ course through the College of Physicians. Another area of expertise is cartography and he has written two books on the mapping of Australia and Antarctica (The Mapping of Terra Australis and So Came They South).

This series of five talks, co-hosted by the Royal Society of NSW and the Sydney Mechanics’ School of Arts, brings together the two oldest institutions in NSW dedicated to education, the discussion of ideas, and discovery. The series is expected to initiate a period of interactive events and activities to the mutual benefit of both societies. The lectures will be presented by an outstanding group of experts in the field, with the topics chosen to represent a broad overview of the Enlightenment from its beginnings as the public recognised and discussed the meanings of change from a long period of mythology and dogma, to grasping reality and what that meant to them and their lives, to its impact on our society today.

The Enlightenment was founded on reasoned discourse and scientific enquiry, connecting with the idea of human equality and the rights of the individual. It was a powerful influence through disruptive revolutions in the 18th century on European and American societies. But what influence did it have on our Australian society, and the institutions entrusted to inform the population of new ideas and discovery? On a more concerning note, to what extent is Nobel Lauriet Joseph Stiglitz correct correct in his view that “Global deflation is reversing international progress through rejection of the principles of the Enlightenment”.

These five Lectures will capture the beginnings of the Enlightenment, its immediate impact on colonial Australia, and two portals of the Enlightenment and their adaptation to changes around them over 200 years. The series will conclude with an interactive Sophistry, taking the theme of the series, and discussing this in the context of contemporary Australian life.

  Columbia University
  New York

Monday 6 November 2017
Ritchie Theatre, John Niland Scientia Building, UNSW

The Dirac Medal for the Advancement of Theoretical Physics is awarded by UNSW in association with the Australian Institute of Physics NSW branch and The Royal Society of NSW. The Lecture and the Medal commemorate the visit to UNSW in 1975 of the British Nobel laureate, Professor Paul Dirac. Professor Dirac gave five lectures which were published as a book Directions of Physics. He donated the royalties to UNSW for the establishment of the Dirac Lecture and Prize, which consists of a silver medal and honorarium. It was first awarded in 1979.

The historical background to Professor Altshuler's lecture goes back to the mechanics of Lagrange following Newton with the integrable systems of equations of motion as deterministic mathematics, in contrast to the ergodic systems describing chaotic motion, known from the Brownian motion of particles. (An ergodic system is one where the position of the points in the system averages out over time, so that if the system runs for a very long time its initial state cannot be determined.) This phenomenon was first observed under a microscope by the 19th-century scientist Robert Brown, and was referred to as the thermo-statistical motion of molecules. This research was further developed by von Oswald, Boltzmann, and last but not least in Einstein’s PhD thesis in Zürich 1905, where he demonstrated that he could arrive at Avogadro’s number. The distance between two molecules increases defining the Lyapunov constant.

Professor Altshuler traced the development of Bose-Einstein statistics leading to the Anderson Localization – for which a Nobel Prize was awarded – and entangled quantum states. These are non-ergodic systems and may be important to the development of quantum computing algorithms.

  “The science of social networks”

  Professor Pip Pattison AO FASSA FRSN

  Deputy Vice Chancellor
  University of Sydney

Wednesday 4 October 2017
Union, University and Schools Club, 25 Bent Street, Sydney

We are social animals and what we think, feel and do is affected by the social networks in which we live work and play. In her talk, Professor Pattison shared with us some of the complexities associated with analysing the structure and dynamics of social networks; including how we can model networks and their consequences.

She began with a brief account of the theory of networks and then described ways we can model their behaviour. The approach construes global network structure as the outcome of dynamic, interactive processes occurring within local neighbourhoods of a network. She described a hierarchy of models and how they may be applied to real social networks using data obtained through various types of network sampling schemes. In particular, she addressed the problem of inferring the nature of the overall structure of a network from knowledge about fragments of the network.

Using several illustrative problems, she demonstrated how the models can be used to enrich our understanding of real network structures in a variety of contexts.  This included how they shape the processes taking place within them, such as the transmission of infectious diseases, and how the models can be used to guide strategies for preventing the spread of such diseases.

Professor Philippa (Pip) Pattison is Deputy Vice-Chancellor (Education) at the University in Sydney, responsible for the University’s strategy and vision for teaching and learning and students’ educational experience. A quantitative psychologist by background, Professor Pattison began her academic career at the University of Melbourne, and has previously served as president of Melbourne’s Academic Board and as Deputy Vice-Chancellor (Academic).

The primary focus of Professor Pattison’s research is the development and application of mathematical and statistical models for social networks and network processes. Recent applications have included the transmission of infectious diseases, the evolution of the biotechnology industry in Australia, and community recovery following the 2009 Victorian bushfires.

Professor Pattison was elected a Fellow of the Academy of the Social Sciences in Australia in 1995. She was named on the Queen’s Birthday 2015 Honours List as an Officer of the Order of Australia for distinguished service to higher education, particularly through contributions to the study of social network modelling, analysis and theory, and to university leadership and administration.

  "Multisensory music:
  listening by ear and eye?"

   Dr Helen Mitchell
   Sydney Conservatorium of Music
   University of Sydney

Wednesday 6 September 2017
Union, University and Schools Club, 25 Bent Street, Sydney

Listening is regarded as the most fundamental way to engage with music performance but this is challenged by a growing body of research which suggests that sight trumps sound. Music is now widely recognised as a multisensory experience, and the challenge for music education is to absorb and include these recent research findings in the music curriculum. This presentation deciphered the complex perceptual skills required for listening to music performers. It described how new experiential learning strategies in music education can prepare future music professionals as critical thinkers about music performance.

Dr Helen Mitchell has a multidisciplinary background in music, as a singer, music scholar and music performance researcher. Listeners’ perception of sound quality is central to Helen's music performance research. Her current work investigates how listeners recognise and describe individual performers’ sound identities, and how listeners ‘hear’ music performers to see to what extent audiences integrate audio and visual information to identify individual performers. 

"Applied remote sensing applications for Australian agricultural and horticultural industries"

Associate Professor Andrew Robson, University of New England

Associate Professor Andrew Robson receiving the Poggendorff Medal from His
Excellency General The Honourable David Hurley AC DSC (ret'd.), Governor of NSW

Tuesday 29 August 2017
Mitchell Theatre, Sydney Mechanics’ School of Arts, 280 Pitt St., Sydney

 With increasing awareness of global food shortages and a downturn in mining exports, Australian agriculture is currently receiving unprecedented industry support and funding for the development and adoption of new technologies. At the forefront of this renaissance is agricultural remote sensing, predominantly due to the advent of drones or UAVs. Whilst the UAV technologies themselves still require much research and development, they have inadvertently increased focus on satellite-based imaging platforms, a technology that has been evolving since the 1970s. The University of New England (UNE) Agricultural Remote Sensing Team (ARST) stands at the forefront of research within this discipline, having established formal collaborations across multiple agricultural industries, and offering support to many more.

In this lecture, A/Prof Robson presented a brief theory of remote sensing with relevance to agriculture, including an overview of commercial satellites and associated costings. The presentation included a detailed discussion of applications currently being developed by ARST, in response to industry demand, ranging from the prediction of fruit size and yield at the individual tree level, the automated derivation and distribution of yield and nitrogen concentration maps to an entire industry and the generation of tools that support national biosecurity and post disaster monitoring.

Associate Professor Robson founded the ARST, a theme of the UNE Precision Agriculture Research Group (PARG), in 2016 on the back of his long-standing research career in agricultural remote sensing. He has been engaged in agricultural research since 1996, with the last 15 years developing spatial applications (remote sensing / GIS) across a number of cropping and farming systems both nationally and internationally. This research has attracted funding from a wide range of industries including peanut (ACIAR, GRDC, University of Florida), grains (GRDC), cotton (CCCCRC), sugar (SRA/SRDC, WWF/ Coca Cola), rice (RIRDC/ NSWDPI), avocados, mangoes, macadamia, banana (Horticulture Innovation Aust/ Federal DAF), vegetables (Horticulture Innovation Aust), pineapples (QDAF) and pastures (CRC-SI/ MLA). Throughout his career, A/Prof Robson has developed an extensive network of industry, research and commercial collaborators that are regularly engaged for the development and delivery of practical and adoptable outcomes.

The Poggendorff Medal

Walter Poggendorff was a biologist and plant breeder with a particular interest in the breeding of rice.  In 1928, the Yanco Rice Research Station was established by the NSW Department of Agriculture with approximately 670 acres just south of Leeton on the banks of the Murrumbidgee River.  A brilliant young biologist, Walter Poggendorff was transferred there as an assistant plant breeder.

Poggendorff’s early accomplishments included recognizing the need to quarantine imported rice and producing strains of rice that were able to offer growers late, mid-season, early and very early short-grain varieties.  He also developed similar long-grain strains but these were not required by the market until much later.  Poggendorff is recognised as one of the major figures in establishing the Australian rice industry, developing high-yield crops for Australian conditions and maintaining controls on imports to limit the introduction of serious diseases.  Poggendorff’s work was not confined to rice – in the 1930s and 1940s, he worked with peaches, apricots, pears, almonds, grapes and rock melons.  Later, he became Chief of the Division of Plant Industry in the NSW Department of Agriculture.

When he died in 1981, he made a bequest to the Royal Society of NSW to fund a lecture.

“The future of rationality in a post-truth world”

Hosted by His Excellency General The Honourable David Hurley AC DSC (ret’d.), Governor of NSW and Patron of the Royal Society of NSW

Wednesday, 29 November 2017, 9am–4.30pm
Government House, Sydney

This year’s Forum discussed the implications of the rise of a ‘post-truth’ approach to shaping public opinion.  Does it have the potential to undermine the institutions upon which open, democratic societies are built?  Does it advantage the propagandists and those who wish to pursue sinister agendas?  What public responsibilities do the traditional and emerging media have?  What should – or can – those who believe in evidence-based, objectively-determined policy do about it?  Distinguished scholars from Australia, New Zealand, and England addressed the following topics:

• Rationality and post-truth: the threat to democratic society - Dr Donald Hector AM FRSN

• Wind Turbine Syndrome: a communicated disease - Prof Simon Chapman AO FASSA

• The Brexit experience: evidence, expertise and post-truth politics - Prof James Wilsdon

• Role of evidence and expertise in policymaking - Sir Peter Gluckman FRS

• Influences on evidence… putting the cart before the horse - Prof Lisa Bero

• Why are scientists so quiet? … the public voice of the scientist - Prof Emma Johnston FRSN

  “Self-driving cars: will they help?”

   Professor Ann Williamson

   Director
   Transport and Road Safety Research Centre
   School of Aviation, UNSW Sydney

Wednesday 2 August 2017
Union, University and Schools Club, 25 Bent Street, Sydney

Autonomous vehicles and driver-assist technologies are seen as the 'next big thing' in transport and road safety. Many authoritative organisations are predicting benefits of up to 95% reductions in road traffic crashes: levels never achieved before. She argued that these forecasts are at best optimistic and at worst misleading, as they are based on the false ideas that driver error is at the heart of almost all road safety problems and that new technology is infallible. Ann's presentation described the main issues associated with different degrees of human- autonomous vehicle interactions using examples from aviation and road transport. She showed how some apparently beneficial technological advances can increase the likelihood of accidents by overwhelming a driver with information and because of the time involved in humans responding to problems arising.  She emphasised the need to act now to refocus the introduction of new technology in vehicles towards making them more usable tools for people if we are to maximize their benefits.

Ann Williamson is Director of the Transport and Road Safety (TARS) Research Centre and Professor of Aviation Safety at UNSW Sydney. She is a Fellow of the Royal Society of NSW and of the Australian College of Road Safety. She has a PhD in Psychology, was Foundation Director of the NSW Injury Risk Management Research Centre and previously Head of the Human Factors and Ergonomics Unit at the National Institute for Occupational Health and Safety. Ann’s research focusses on human factors and injury in the areas of transportation and workplace safety, in particular on the role of error, especially skill-based error, in safety and the effects of fatigue on performance. She has been an invited technical expert on advisory committees for a wide range of transport and road safety authorities. She has twice been awarded an NHMRC Senior Research Fellowship (2005-2015) and won the Ron Cumming Memorial medal from the Human Factors and Ergonomics Society of Australia (2013), the Sustained Achievement over a Professional Career Award (2011), and the Meritorious Achievement in Research Award (2004). She has been President of the Australian Injury Prevention Network.

  “Quantum computers: how and why”

  Andrea Morello
  Professor of Quantum Engineering
  UNSW Sydney

Wednesday 5 July 2017
Union, University and Schools Club, 25 Bent Street, Sydney

The talk certainly lived up to its promise of giving an excellent insight into a subject that, for most of the audience, would be far removed from their professional knowledge and experience. Starting out with a simple demonstration of how quantum effects are size dependent, Andrea went on to describe some of the current realisations of quantum devices that can manipulate one bit of information – a qubit – and, in particular, the device pioneered by his group, which uses the coupling between the nuclear and electron spin of a phosphorus atom in silicon. However, a single qubit device is, in principle, functionally no different from a single memory cell in a normal silicon chip. The big difference between current computers and a quantum computer arises through the effect of entanglement, which allows N entangled qubits to be manipulated as a single entity with 2N states (a memory chip with N cells can also store any one of 2N different “words”, but such a word can only be changed bit by bit). The promise of enormously enhanced computing power is currently being pursued in a number of corporations, including Google, IBM, and Lockheed Martin, and here in Australia a consortium of Andrea’s group at UNSW, Telstra, and CBA, with Government support, is being created to stay in the race – the Royal Society of NSW wishes them lots of success. The great interest in Andrea’s presentation was demonstrated by the vigorous Q&A session that followed, which explored some of the challenges

  “Are you smarter than a slime mould?”

  Madeleine Beekman
  Professor of Behavioural Ecology
  University of Sydney

Wednesday 7 June 2017
Union, University and Schools Club, 25 Bent Street, Sydney

Professor Madeleine Beekman presented her investigations on the slime mould, a unicellular organism with no brain or central nervous system, but as smart as we are (well, maybe). Over the last few years the acellular slime mould, Physarum polycephalum (literally the multi-headed slime mould) has emerged as a model system for decision making. Despite its simplicity, this organism is capable of rather complex behaviour, which was illustrated by Madeleine in a number of fascinating time-lapse videos. Not only is the organism able to detect the presence and location of food (and to discriminate between oats from Woolies and Coles!), which might be considered simply a chemical process, but it is able to determine the shortest of possible routes to the food, and also to display an efficient strategy for hunting for distributed food sources of varying quality. This behaviour raises a number of questions about the meaning of such concepts as intelligence and cognition, and about fundamental processes underlying all decision-making. These questions, as well as Madeleine’s very engaging style of presentation, led to a vigorous discussion, which would have provided many of us with food for further thought

    “Sensing our world: From glucose sensors to
    counting single molecules and cells”

    Scientia Professor Justin Gooding
    University of NSW

    Awarded the 2017 Liversidge Medal for
    chemistry.

Thursday 11 May 2017
Tyree Room and Balcony, John Niland Scientia Building, UNSW

Biosensors are solid state analytical devices made by integrating a biological molecule that can recognise a biomarker of interest with a signal transducer, such as an electrode or optical instrument. The classical examples of such devices are the glucose meters that have revolutionised the lives of diabetic patients, and pregnancy test kits. There is a whole family of related devices developed for uses ranging from disease diagnosis to water quality testing.
This presentation covered the state-of-the-art research in this field, explored some of the challenges to wider adoption of such devices in daily life, and outlined the work of the Smart Materials and Surfaces research group at UNSW in this area. It also discussed some advances in surface chemistry and nanotechnology that will lead to the next generation of sensors that detect single molecules and cells. Such devices not only represent the ultimate sensor in being able to detect a single thing, but will solve many challenges with existing sensor technologies. By being able to detect many single moelcules or cells, such that the devices essentially count the number of entities to be measured, they will solve the main challenges in sensors of calibration and nonspecific signals, as well as create a whole new type of sensor. The presentation concluded with a discussion of some of his groups recent work on bringing this exciting vision of our sensing future towards a reality.

Scientia Professor Justin Gooding FAA, FISE, FRSN, FRACI, FRSN is currently an ARC Australian Laureate Fellow, the co-director of the Australian Centre for NanoMedicine and the co-director of the New South Wales Smart Sensing Network.

  “The science of beer”

  Dr Greg Organ
  Senior Sensory Specialist
  Lion Company

Wednesday 5 April 2017
Union, University and Schools Club, 25 Bent Street, Sydney

Dr Organ began with a description of beer’s four ingredients – yeast, water, malt and hops – and the brewing process. To fully enjoy your beer you need to fully utilise your senses and the talk then moved to describing the role of each of the senses. The basics of sensory science were used to illustrate how the senses can be used to gain scientifically valid information through trained tasting panels. The sensory properties of the main flavours of beer were next described together with some of the chemistry involved. The talk concluded with a brief mention of Lion’s marketing campaign “Beer The Beautiful Truth”. During the talk some practical hints as to how to enjoy your beer at its best were included!

Dr. Greg Organ is the Sensory Specialist for Lion. After gaining a PhD in Inorganic Chemistry at the University of Sydney he worked for two years at the Research School of Chemistry, Australian National University. After this he made a major change in research area and worked for two years on the chemistry and sensory evaluation of wine at the Australian Wine Research Institute, Adelaide. Since then he has been the sensory and flavour scientist for Lion for nearly thirty years. He is responsible for the training, procedures and operation of all of Lion’s sensory evaluation panels. He also does the more complex flavour analytical work for Lion and some research work into the flavour chemistry of beer. He is well known within the Australian and New Zealand sensory science community and has made many presentations to a wide range of groups on beer science.

 
  “Creative minds: Artistic and scientific
  endeavour on polar expeditions 1851 to 1951”

  Richard Ferguson FRGS
  Executive Director, Craft Australia

Wednesday 1 March 2017
Union, University and Schools Club, 25 Bent Street, Sydney

Increased specialisation of academic disciplines in the twentieth century has for many lead to the view that Art and Science are at polar opposites when it comes to the value and contribution that art disciplines have made to scientific expeditions. Richard gave an overview of artistic endeavor on early scientific expeditions such as those of Cook / Endeavour 1768, 1771, Baudin / Geographe 1800 - 1803 and Fitzroy / Beagle 1831 - 1836, and how this directly influenced the application of photography on polar expeditions. There is a mounting body of illustrative and taxonomic artistic works being produced as documents of record on scientific and exploring expeditions. The more dramatic and romantic views such as, The Icebergs (1861), created by Hudson River School artist Fredrick E Church (1826 -1900) and Sealers Crushed in Ice (1876) by New Bedford born artist William Bradford (1823 û 1892) are what captured the imaging of the public. The productive mix of art and science was demonstrated through an analysis of over 1,000 images, from three nineteenth century arctic expeditions: William Bradford 1869; Benjamin Leigh Smith 1873, 1880; and George Strong Nares 1875 û 1876. Richard also discussed a re-photographic survey of the Antarctic work of Australian photographer Frank Hurley undertaken over five expeditions between 1987 and 1996.

Richard Ferguson has been involved in the cultural, heritage and education sectors for more than 30 years in both Australia and England. His initial tertiary training was at the National Art School, Sydney and later training in visual arts and photography enabled him to undertake original research and Antarctic field work on five expeditions with the Australian Antarctic Division and commercial operators. His particular area of interest is the use of photography on polar expeditions, which was initially based at the Mawson Institute for Antarctic Research at the University of Adelaide, Scott Polar Institute, Cambridge and then the South Australian Museum. This research, curatorial work and collections management gave rise to increasing involvement in the management of a variety of cultural projects at various museums and galleries. These include: Australian National Maritime Museum; Geelong Gallery; National Maritime Museum, Greenwich, one of twelve lead National Museums of England; and the Melbourne Cricket Club. Prior to that he was Manager of the Museums Australia Museums Accreditation Program. He was elected as a Fellow of the Royal Geographical Society in 1993 for his polar research and fieldwork. He is a member of the Royal Society of Victoria and currently a National Council Member of the International Council of Museums, Australia.

  “South Australia: a nuclear State in a global
  solution”

  Rear Admiral, The Honourable Kevin Scarce AC
  CSC RAN (ret'd.)

Thursday 23 February 2017
International Convention Centre, Darling Harbour

This talk focused on the challenge to Australia in moving to a reliable, low-carbon and lowest-possible-cost electricity system. Nuclear power is a proven, low-carbon energy source and may have a role to play in Australia. South Australia has abundant uranium resources and furthermore, with the combination of geological, political and technical factors, the State may provide a global solution for the permanent disposal of used fuel. The benefits of being a nuclear State could be game-changing.

Rear Admiral, the Honourable Kevin Scarce is the 16th Chancellor of the University of Adelaide and was the 34th Governor of South Australia from 2007 to 2014. He served in the Royal Australian Navy from 1968, retiring in 2004. His appointments included service on HMAS Sydney during the Vietnam War. He specialised in military logistics and procurement, rising to the rank of Rear Admiral and Head of Maritime Systems at the Defence Materiel Organisation. After retirement, as Head of the South Australian Defence Unit, he led a government team that contributed to ASC winning the contract to build air warfare destroyers for the Australian Defence Force. He was awarded the Conspicuous Service Cross in 1994, the Knight of Grace in the Venerable Order of Saint John in 2007 and a Companion of the Order of Australia in 2008. He completed a Bachelor of Financial Administrationfrom New England, Masters of Management Economics at the University of New South Wales (Australian Defence Force Academy campus), and a Masters Degree in National Security Strategy at the US War College (National Defense University) in Washington, DC. He was awarded an Honorary Doctorate from Flinders University in 2009 for distinguished service to the public of South Australia and an Honorary Doctor of Letters (honoris causa) from the University of New England in 2014. He was appointed on 29 March 2015 as the Commissioner of the South Australia Nuclear Fuel Cycle Royal Commission.
