Postera crescam laudeI shall grow in the esteem of future generations

The University of Melbourne is a centre of cultural and intellectual life in Australia. Founded in 1853, the university commenced teaching its first students in 1855. Its main campus is located just north of Melbourne’s city centre. It is ranked as one of Australia’s highest research-intensive universities. Reinforcing Melbourne’s position as one of Australia’s leading research universities is our ability to attract Australian Postgraduate Awards (APAs), which are awarded to researchers of great promise. The most recent annual figures saw Melbourne receive 174 APAs – more than any other Australian university. Among those teaching and conducting research at the University of Melbourne are many people of international standing and reputation.

As one of Australia’s oldest universities, the University of Melbourne has a long history of welcoming international students and has a sophisticated understanding of the infrastructure and specialized support where required.

In 2005, the University of Melbourne was ranked #1 study, The International Standing of Australian Universities. This follows the worldwide ranking of the University at #22 by the Times Higher Education Supplement. Internationalisation is essential for the development and growth of the University of Melbourne.

To th i s end the Un i ver s i ty has : Developed formal international exchanged agreements with over 100 institutions worldwide;

Established the Eminent Scholars Scheme – an innovative program designed to enhance our teaching and research environment;

Included distinguished members of the global higher education community in its governing council. The current international member is Professor John Hood, Vice-Chancellor, University of Auckland;

Helped to create the prestigious Universitas 21 network – an international network of 17 research-intensive universities in ten countries.

The University’s leading role in setting up and supporting Universitas 21 has greatly lifted its reputation in Europe, the United States and Asia. For further information visit http://www.universitas21.com/.

The University has established strong links with industry. The University of Melbourne is a core participant in 21 of 26 Cooperative Research Centres and is a supporting participant in the remaining few. The Government’s Cooperative Research Centre Program, launched in 1990, fosters links between industry, educational institutions and government to encourage world-class research and to offer business an opportunity to collaborate with research institutions on R&D relevant to industry needs. The benefit of such alliances to postgraduate students is that they have access to state-of-the-art facilities and their learning is informed by the latest research conducted by world-class academics.

INTERNATIONALLY RECOGNISED FOR ACADEMIC EXCELLENCE

The University of Melbourne>The Faculty of Science was established in 1903 at the University of Melbourne, under the first Dean, Professor Henry Laurie. The Faculty provides a range of teaching and postgraduate training programs and community services, based on a solid foundation of research in the pure and applied sciences. It comprises four schools and five departments - Botany, Chemistry, Earth Sciences, Physics, Genetics, Information Systems, Mathematics & Statistics, Optometry & Vision Sciences, and Zoology, and it has an active involvement in 13 competitively funded research centres. Over 6,500 undergraduate and postgraduate students are enrolled across its 10 undergraduate and 12 postgraduate courses and its Honours program.

Faculty staff gain approximately $22 million a year in competitive research grants, through peer-assessed grants, the Australian Research Council (ARC), the National Health and Medical Research Council (NHMRC) and other national funding and industry agencies. Its international agenda includes joint research ventures, exchange of staff and students, recruitment of overseas students and the inclusion of a global perspective in curricula. Through the quality of its research and teaching, the Faculty enjoys a strong reputation, both nationally and internationally.

HEAD'S REPORT

The annual report of the School of Physics is an important communication between the School, the University and the broader community. We are delighted that you are taking the time to consult it.

The work of an academic department takes many forms but teaching and research are at its heart. In the pages of this report you will find a snap-shot of our research and teaching activities in 2005. In doing so, we celebrate the achievements of our students, including those who have won academic prizes and those who have completed degrees. The report also celebrates the achievements of our staff, including the papers they have published and the research grants they have been awarded. We celebrate the diversity of our staff and students, their interests and backgrounds. We are passionate in our commitment to highest standards in teaching and research in physics.

GROWING ESTEEM & FUTURE DIRECTIONS

Guided by the University of Melbourne’s strategy of Growing Esteem, our community of staff and students continue to contribute strongly in each of the three important elements of a world-class university:

Research – Faculty of Science researchers operate at the highest levels internationally across a breadth of disciplines, contributing to the store of human knowledge, finding applications that benefit society and informing teaching programs which position our students for the international marketplace;

Learning and Teaching – attracting the best and brightest from around Australia and internationally, Science at Melbourne offers a broad range of disciplines to prepare scientists and professionals for the challenges of tomorrow;

Knowledge Transfer – by engaging with industry, schools and our community, locally and around the world, our staff, students and alumni are able to define, analyse and help solve complex issues in science and business.

EXECUTIVE MANAGER'S REPORT

The Teaching and Research effort of the School has been well supported again this year by excellent professional staff. Joanne Kuluveovski joined the School as Research and Communication Officer to support the School’s research effort. Kristine Philipp was employed as administrative support to the Head while Julie Warden, formerly with Human Resources at the university, moved across to support the finance team within the School.

Within the IT group, we farewelled Tas Dionisakis and Nick Savvides who both moved onto positions within the university. They are replaced by Kathryn Sparks, Simeon Scott and Linh Vu.

Later in the year, Jude Prezens joined Nick Nicola in the undergraduate laboratories, while Michael Gangoiti moved to the administration team primarily to replace Ms Mary Fernandes on reception.

Building works have included the refurbishment of the professorial offices on Level 7, the development of a teleconference room, the installation of a new chiller in the basement and the commencement of a major upgrade of the Geoff Opat Seminar Room. Level 2 offices were also refurbished to create space for the newly funded QCV group. The IT office area was upgraded to accommodate all the staff in one central area. A new office space has also been created in Level 1, utilizing better the space formerly occupied by the sick bay area.

Group Reports & Publications>ASTROPHYSICS

PROF RACHEL WEBSTER

The Astrophysics group has continued its strong research program and its commitment to a successful research training program.

Dr Stuart Wyithe was appointed to the new faculty position in the group in 2004. He has continued his research collaboration with Professor Avi Loeb at Harvard, working on the Epoch of Reionisation and the formation and evolution of supermasssive black holes. During 2005, Stuart has started supervising his first PhD student, Jhan Srbinovsky, working on the Epoch of Reionisation.

Dr Andrew Melatos has further developed his models of gravitational radiation from accreting neutron stars, with promising predictions for the possibilities of detecting this radiation with the current generation of long baseline interferometers such as LIGO. In addition, Dr Melatos published the results of his Gemini observations of the Crab pulsar wind nebula. His collaboration with PhD student Peralta and Dr Andrew Ooi’s group in Mechanical Engineering at Melbourne yielded new results in superfluid hydrodynamics, with laboratory applications.

Dr David Barnes resigned to follow his passion of photography. Dr Barnes has made a substantial contribution to the development of the Australian Virtual Observatory, www.aus-vo.org, and also to the ongoing analysis of the HIPASS dataset.

Professor Rachel Webster continued her work on the microlensing of lensed quasars, a project which will develop new techniques to measure the sizes of quasar emission regions. This program was supported by a large allocation of Gemini time. Professor Webster was the inaugural Caroline Herschel Distinguished Lecturer at the Space telescope Science Institute in June 2005.

During 2005, the Melbourne group worked with collaborators at MIT and Harvard to deploy 3 tiles at Mileura Station in WA. This project was managed by David Barnes, who was assisted by Jamie Stevens, Randall Wayth and Chris Johnston. The deployment was spectacularly successful, with at least two publishable results from the first datasets.

Five PhDs were awarded in the group in 2005: Drs Donald Payne, Cathy Trott, Randall Wayth, Arna Karick and Jamie Stevens. In addition, PhD student Ivy Wong spent a year working at Johns Hopkins University in Baltimore, with Dr Gerhardt Meurer, and PhD student Matthias Vigelius spent two months at Harvard, working with Prof Bryan Gaensler. Research Fellows Neil Killeen and Mark Dijkstra also joined the Astro group.

In 2005 Roger Rassool became the 4th academic member of the EPP group, following the closure of the Photonuclear Group within the School. We've benefited greatly from Roger's contributions in the areas of detector physics and his links with external organizations such as the Australian Synchrotron and the Austin Hospital. In addition 2005 saw Markus Bischofberger (Atlas analysis) and Marco La Rosa (grid development) join us as postdoctoral fellows and Jared Winton was hired as an engineer for Silicon Detector development.

The group’s activities focused mostly on the Belle experiment currently collecting data at the KEK laboratory in Japan and the ATLAS experiment, under construction at the CERN lab in Geneva, Switzerland. We continued to lead the Australian deployment of computational GRID technology within Australia and initiated the collaboration with the PSI lab in Switzerland for the development of pixel detectors for Synchrotron radiation science.

At Belle we study CP violation (the difference between matter and anti-matter), rare decays sensitive to Physics beyond the Standard Model, and make precision measurements of the CKM parameters Vcb and Vub. For the ATLAS experiment we have constructed detector modules for the Silicon Central Tracker (SCT), developed power supplies for the SCT, and have designed and constructed 4200 in-line filter and voltage limited systems. These have been mounted in 13 large electronics racks directly beside the ATLAS detector in the main cavern. In addition to these hardware contributions we are developing software to significantly speedup detector simulation and have designed algorithms for the reconstruction of electrons which have a complex trajectory in the ATLAS detector.

When ATLAS begins operation in 2007 it will produce roughly 15 million gigabytes of data per year, equivalent to 3 million DVDs or 1% of the total global digital information output. The Worldwide LHC Computing grid (WLCG) is a massive, distributed, international computing infrastructure designed to enable analysis of this enormous data set. It coordinates and shares processing power, data, applications

and network resources from many thousands of linked computers. The EPP group has played a leading role in the development of grid and has deployed a grid infrastructure across 300 computers at 5 facilities in Sydney, Canberra, Melbourne and Adelaide. In 2005 this grid was used to simulate complex particle collisions in the Belle experiment and to participate in ATLAS data challenges.

We are looking forward with eagerness to the commencement of ATLAS data taking scheduled for late 2007. We have worked for many years to build up the hardware, software and data analysis skills needed to explore the data obtained at this frontier experiment. The ATLAS experiment will explore the nature of Electroweak Symmetry Breaking at an energy regime almost guaranteed to discover new physics.

Over the past twelve months the Melbourne node has been deeply involved in the production of counted atom devices, especially the routine production of two atom devices for the charge qubit experiments. With the advent of exciting experimental data on some of these devices, the device modelling program has also been deeply involved in the interpretation of this data. All this work has proceeded in close collaboration with the other nodes of the Centre.

The production of counted atom devices depends on ion implantation using on-chip integrated detectors. This process underwent further optimization in 2005 to improve reproducibility and reliability. A particular challenge was to make the integrated detector structure compatible with subsequent fabrication of increasingly sophisticated and complex nanocircuitry for control and readout of the charge configuration of the device. We developed a strategy using buried heavily doped wells set back more than six microns from the implant sites leading to electrical contacts that-are more than 500 microns further back. This keeps the construction site free from metal contamination. In 2005, more than 25 devices were fabricated with the new detector structures and some of these were employed in competed devices that went through to measurement. The highlights of these measurements are presented in the report from the New South Wales node. Given the very promising data being obtained on these devices we anticipate further developments within the Ion Beam Program, in close collaboration with the Integrated Quantum Computer Device Program, of the single ion implantation system with the view to perform the implantation at lower energies in conjunction with a thinner surface oxide to improve the lateral precision.

The issue of how phosphorus implanted into silicon at the very low concentrations needed for quantum computer devices was addressed in detail by the Materials Program. In collaboration with Dr Wayne Hutchinson of ADFA, electrically detected magnetic resonance was observed for the first time in an ion implanted device. This allowed us to check that the implanted phosphorus was electrically active and this work was complemented with our in-house deep level transient spectroscopy system that allowed us to measure the density of electron

traps at the interface between the gate oxide and the silicon substrate. This is a critical issue for Si:P architectures. The problem of dopant activation was addressed in the Atomic Level Manipulation and Imaging Program where highly sensitive Scanning Kelvin Microscopy images were taken of the buried charge created by both P and Si implanted silicon. The Si control implants yielded signals below the noise level which itself approximates to the signal that would arise from an array of charge traps spaced by approximately 70 nm, which exceeds the typical inter-qubit spacing utilised in qubit test devices showing implantation damage has been repaired. The issue of the activation of extremely low concentrations of implanted phosphorus ions remains open but we hope to resolve this issue in 2006 once a suitably sensitive alternative analysis method is developed. However the Hybrid Optical Sold-State Program provided extraordinarily sensitive measurement on ensembles of as few as 104 single P donors and pairs of P donors. These measurements provide information on the Heisenberg exchange constant, J, which is an indication of the wavefunction overlap between donor pairs.

The exciting results from the Quantum Measurement Program showing controlled single charge quantum transfer has spurred the more detailed modelling of the charge transfer process which has greatly assisted with data interpretation. A particular challenge has been the modelling of charge transfer in a counted four atom device. The results from the modelling are consistent with all four atoms being active as donors and that microwave induced charge transfer events were possible under a narrow set of configurations of the device – consistent with the experimental data. The Device Modelling Program team also reached several important milestones with the development of architectures for the transport of single electrons in a process describes as Coherent Transport by Adiabatic Passage (CTAP). This allows separation of qubit interaction zones from readout zones in a two dimensional multi-qubit device. The Device Modelling Program also keeps watch on developments in quantum computing schemes that complement the Si:P system. Some schemes, such as those that involve N-V centres in diamond, have the potential to provide single photon sources or strongly coupled light-matter

interactions when fabricated into quasi periodic photonic band gap cavities which may be useful in the readout of Si:P qubits. Much of the work in the Device Modeling Program was given a tremendous boost from the two visits of Prof Sankar Das Sarma, University of Maryland, in February and October of 2005. Prof Das Sarma also gave a major public lecture during his October visit which attracted over 400 people to hear about his vision of quantum mechanics in future technology.

Staff, postdocs and students were in high demand in 2005 for lectures at scientific conferences but were also keen participants in the vast range of activities that took place in 2005 to mark the UN-declared International Year of Physics. We were involved in more than 30 events which often featured the work of the Centre presented to large and enthusiastic audiences of the general public. For 2006 we look forward with keen anticipation to the realization of Si:P qubits.

Research Highlights

In an often-crowded and vibrant atom optics lab, Assoc Prof Robert Scholten and his team continued their work on novel approaches to imaging cold atoms, developing a minimally destructive, quantitative, yet experimentally practical method. The insight of PhD student Lincoln Turner led to an elegant approach, in which the diffraction pattern of cold atoms illuminated by an off-resonant laser beam is computationally inverted to provide an image of the atoms. The technique offers great promise as an easy yet precise method of phase imaging, for both cold atoms and for some applications of x-ray imaging. Lincoln left the group mid-year, with a Fulbright Fellowship to work with Nobel Laureate Bill Phillips at NIST, Washington DC.

The lab also demonstrated a blue laser based on establishment of a coherent quantum superposition of atomic states. Energy was converted with unprecedented efficiency, to generate a coherent blue beam – like a laser, but without mirrors. The work was published on the front cover of the Australian Optical Society News in March, and in Optics Letters.

The coherent x-ray group published a total of 12 refereed papers, including some work on a new approach to coherent imaging, and two papers on the work of Benedicta Ahartari on phase-contrast radiography. In particular, its work on diffractive imaging with curved wavefields is grabbing international attention.

In October A/Prof Roberts presented a paper on one aspect of this research at the Optical Society of America Annual Meeting in Tucson. She also visited Singapore and, with PhD student Nicole Tse, obtained the first in-situ Electronic Speckle Pattern Interferometry images of canvas paintings in the Singapore Art Museum. While in Singapore, she gave seminars at the National Heritage Centre and the National University of Singapore and also visited the Singapore Synchrotron Light Source and the Centre for Ion Beam Applications.

The precision x-ray optics team continues its work on pinning down physical constants to unprecedented resolution and published a number of very high quality publications in this area. The group was heavily involved in the international X-ray and Inner Shell Processes Conference held in Melbourne (X05, 4-8 July 2005). Assoc Prof Chris Chantler was Scientific Chair and Editor of the refereed proceedings, Group members continue to be invited to present at conferences around the world.

Grants

A collaboration led by Keith Nugent was successful in being awarded ARC, University and Victorian State Government funding to establish the Centre of Excellence for Coherent X-ray Science. The Centre is a major coup for the School of Physics, bringing together outstanding research groups from the Schools of Physics and of Chemistry, the Australian Synchrotron, CSIRO, Latrobe, Monash and Swinburne Universities, and a number of prestigious international partners.

Robert Scholten and Ann Roberts were successful in receiving an ARC Discovery Project grant, ‘Quantum and classical imaging with light and atoms’ to extend our innovative research in physical optics to quantum optics.

Students and Visitors

In 2005, the atom optics group enjoyed the year-long sabbatical of A/Prof Jamie White from Juniata College in the USA, and long stays by several visiting PhD students from The Netherlands including Thijs Meiijer, Kenian Domen, and Bart Smeets, through our collaboration with the quantum-atom-optics group at Eindhoven University.

Martin de Jonge completed his PhD ‘with distinction’ (top 5% of all PhDs) according to the examiner, who wrote ‘these careful measurements will continue to serve as THE yardstick for measuring the performance of future theories for a long time.’ Well done, Martin.

Adrian Mancuso completed his PhD and commenced work with Quantum Communications Victoria, housed within the School. Former student, Magda Michna, now at McGill University in Canada, was awarded her PhD in December and Peter Pace (now at Victoria University) received his MSc in August.

Research carried out within the TCMP group in 2005 can be classified into two general areas: Imaging of condensed matter systems and the dynamics of dilute gas BECs. The research carried out has resulted in a total of nine publications (three in the prestigious Physical Review Letters, the flagship journal of the American Physical Society and one in Applied Physics Letters). The academic staff in the group, Assoc Prof Les Allen and Dr Andy Martin each delivered three invited contributions at international conferences. The software IWFR, used for phase imaging at atomic resolution in electron microscopy, developed in the Allen subgroup, was successfully commercialized in conjunction with the Japanese company HREM Inc.

The group was funded by two Australian Research Council (ARC) Discovery Project (DP) grants and one Melbourne Early Career Researcher (ECR) grant, worth $164,500 in 2005. The DP grants have enabled the appointment of two postdoctoral research fellows in the group, namely Dr Scott Findlay and Dr Nicholas Parker. The ECR grant has established computer facilities and provided travel money for Dr A M Martin’s subgroup.

Strong international collaborations have been a feature of the research done. Link are in place with the Oak Ridge National Laboratory, The SuperSTEM Facility at Daresbury, Trinity College Dublin, Nottingham University, Imperial College London, The University of Otago, The Massachusetts Institute of Technology (with the group of Nobel Prize winner Prof W Ketterle) and the University of Durham.

The theoretical particle physics group continues to thrive as it manages generational change of its permanent academic staff.

After almost thirty-five years of dedicated service to the School of Physics, Dr Girish Joshi retired from teaching and administration at the end of 2005. He remains active in research, continues to supervise PhD students and holds a joint ARC Discovery Project grant for 2006-2008 with Bruce McKellar and Ray Volkas. It is appropriate to reflect on Girish’s long career, which has seen him publish almost 200 papers and supervise more than a dozen PhD students. Research Fellow, Dr Alexandre Ignatiev also left the group. We welcome Dr Adrian Flitney who was awarded Australian Postdoctoral Fellow.

Dr Nicole Bell will join us on 1 January 2007 as a new continuing Lecturer in theoretical particle physics. After completing her PhD at Melbourne with Ray Volkas, she was a postdoc at the influential theoretical astrophysics group at Fermilab for three years, and is presently a Sherman Fairchild Scholar at Caltech. She has won numerous awards, and has written several very influential papers in particle cosmology and astrophysics as well as in straight theoretical particle physics.

The Head of the TPP group, Professor Bruce McKellar, shall effectively retire from teaching and administration at the end of 2006. During 2006, we shall run a search for a second continuing lectureship to fill his shoes (very large shoes to fill!). So, from 2007 we anticipate having a new-look group under the leadership of Ray Volkas, with Bruce and Girish continuing to be very active in research as honorary staff.

In 2005, the TPP group had 13 PhD and Masters students active in theoretical particle physics research, and two research fellows. The currently active research fields cover physics beyond the standard model, including brane-worlds, extra-dimensions and gravity, as well as particle cosmology and high-energy astrophysics. Particle physics worldwide has for some time been broadening into a cross-disciplinary effort involving our friends the astrophysicists and cosmologists, and the TPP group’s research

efforts exemplify this trend. We are also keenly awaiting the Large Hadron Collider, and looking to enhance our already strong links with the experimental particle physics group.

Group member Associate Professor Lloyd Hollenberg continues to lead Melbourne’s theory effort within the ARC Centre of Excellence for Quantum Computing Technology, supervising a large number of research students and two postdocs. Good progress has been made in their efforts to construct a solid state quantum computer, a project to be described in more detail elsewhere in this annual report.

QCV was established within the School of Physics in July 2005. QCV is funded by a State Government of Victoria Science, Technology and Innovation (STI) grant in addition to support from the Faculty of Science. QCV is an Unincorporated Joint Venture between The University of Melbourne, MagiQ Technologies (New York and Boston), Qucor Pty Ltd and Silicon Graphics Inc. The program has three major milestones to meet over the course of the next three years:

* Development of a prototype single photon source based on diamond

* Enhance the communications abilities of our research staff and offer similar services to external clients

* Engage industry to determine their interest in Quantum Communications and their possible involvement

The first 6 months of the program have been dedicated to corporate branding and establishing the QCV team, including new staff Dr Elizabeth Trajkov, Materials Engineer; Dr Steven Trpkovski, Photonics Prototype Development Engineer; and Mr Hugh Wilson, Research Fellow, all arriving in 2005.

To date this process has been highly successful with the establishment of the QCV office on Level 2. The majority of the staff positions for the program have now been filled with a variety of research, commercial and administrative staff. The team has also successfully submitted to Government the Commercial, Marketing, Technical, and Industry Engagement Plans for the next 3 years.

Initial discussions for the formation of a QCV corporate entity have also been initiated in order to capitalise on investor interest in the program. This strategic plan will enable the continuation of the QCV program well beyond the end of the State Government funding period.

The QCV is directed by an Executive Board consisting of members from each of the Joint Venture Partner organisations. In addition, a prestigious Industry Advisory Group has been established to provide expert advice on a range of commercial topics.

A key challenge for a commercially driven program such as the QCV is to demonstrate value to the School of Physics with regards to the traditional areas of teaching and research. To this end the program is proud to support numerous research programs through the acquisition of equipment, staff resources, collaborations, and the provision of student scholarships. Members of the QCV have been encouraged to engage in teaching and have strong involvement in the school’s outreach programs.

The QCV program is providing an opportunity for a crossover between a variety of sectors. Collectively, the team represents all of the sectors involved in commercialisation. It is my strong feeling that the existence of this program within the school will greatly benefit our traditional research and teaching programs in addition to meeting the new demands for knowledge transfer being placed upon us all.

PPSS >POSTGRADUATE PHYSICS STUDENT SOCIETY (PPSS)

DR STUART WYITHE

Within the School of Physics, postgraduate research is an integral part of all research areas. Physics postgraduates are therefore integrated into School life at all levels. For example, the crucial role played by students in the research success of the School is highlighted during the weekly postgraduate seminar series. This series serves to inform the School as a whole of individual research programs.

In addition, the seminar series offers our students valuable experience in scientific and oral presentation skills. Postgraduate students are also integrated into the day-to-day workings of the School through representatives on each of the Schools committees. Postgraduate student participation on School committees is coordinated by the Postgraduate student society, and aims to ensure that postgraduate student needs are met at all levels.

The School aims to assist postgraduates with the skills they will need to successfully complete their degree and to move forward in the future. To prepare postgraduate students to make the most of their time within the department, the School conducts an induction day, where the roles and perceptions of students and supervisors alike, as well as the requirements of postgraduate study are discussed.

The School organises a focus day for senior postgraduate students to assist with the transition out of postgraduate study. The School also recognises the importance of bridging the gap between undergraduate and postgraduate study. To this end the School organises a Postgraduate student research exhibition. This exhibition showcases the work of our postgraduates to interested 2nd and 3rd year physics students.

Each of the above activities was undertaken during 2005. In 2006, we have already had our induction day, attended by more than 20 new postgraduates. Additionally we will continue to run the Senior Focus day and Research exhibitions. As a new initiative in 2006, the School will expand the postgraduate seminar series to include a full colloquium by final year students, describing the work presented in their thesis. This final colloquium will provide the opportunity for the School to celebrate the achievements of postgraduate students.

PAUL FRASER (PPSS President)

The Postgraduate Physics Student Society (PPSS) is an association of which each postgraduate degree student is automatically a member. It is affiliated with the University of Melbourne Postgraduate Association, which formally provides funding for the range of activities the PPSS undertakes, though the School of Physics significantly supports the PPSS both financially and logistically.

The purposes of the PPSS are to enhance the academic and professional life of its members, encourage social interaction of students within the School, to co-ordinate representation of School of Physics Postgraduate students on School committees and to represent School of Physics Postgraduate Students to the Science Faculty and University.

In 2005, these goals were achieved by running traditionally well received social events such as barbecues and a trivia night, as well as the new addition of a pool competition. On the more formal side, student attendance at the various School committee meetings was high, indicating the enthusiasm of postgraduate students to participate in the running of School and the business of the University that affects the School. Additionally, the PPSS creates leadership positions for its members, enhancing skills prior to entering formal employment.

In 2006 the PPSS aim to continue fulfilling these duties, and with the enthusiastic group of volunteers in office bearer roles and on committees, the coming years should be quite productive.

MUPPETS

MUPPETS stands for Melbourne University Physics Promotion, Education &Teaching Services

Bendigo February Tour

Setting up base at the Bendigo Science Discovery Centre, the Muppets team, led by Dr Roger Rassool, put on 2- 4 shows over 5 days in which nearly every primary school in Bendigo attended. The final show was hugely successful which was open for parents and the general public.

Outback Roadshow

Presented as part of the Einstein International Year of Physics, the roadshow was the biggest and most ambitious yet for MUPPETS . The vehicle convoy, carrying two tonnes of equipment, covered more than 2400 kilometres on its two-week outback itinerary. Led by Physics academics Dr Roger Rassool and Associate Professor Max Thompson, the MUPPETS team of Physics staff and graduate students presented major public shows and workshops in Mildura, Broken Hill and Cobar and visited more than 30 schools along the way. As well as drawing full-house audiences, the roadshow also attracted

significant media attention. The images in this feature were taken by Mildura’s Sunraysia Daily newspaper.

Other MUPPETS Programs

In excess of 3,500 primary and secondary students parents, teachers and careers teachers in Australia and overseas benefited directly from MUPPETS programs this year. Summer schools attracted 490 high achieving students, some of whom will undoubtedly be students of the future for us.

Melbourne Physics Forum at the Melbourne Town Hall

With ABC's Bernie Hobbs as the master of ceremonies, this was a fun day of physics for 1500 Year 10 -12 school students. The day event was designed to introduced Einstein's four big ideas from 1905 and the ghost of Melbourne's own physicist, William Sutherland, who actually beat Einstein to one of these ideas.

The show comprised 4 mini-lectures with demonstrations:

E=mc2 and cosmology presented by Prof Rachel Webster

Brownian motion presented by Dr David Hoxley

Photo-electric effect presented by Dr Roger Rassool

Special Relativity presented by Prof David Jamieson

In addition, alumni were on hand to help out in a discussion panel on physics careers, the role of physicists and the really “big science” questions.

MUPPETS show, Mildura

Alumni & Friends >The School of Physics renewed its focus with alumni and friends with the development of the Alumni Physics Newsletters. These have been well received, especially by the physics community who now live overseas, as a way of keeping in touch.

In February, we hosted a Cocktail party reunion which proved to be a great success. Young and old took up the opportunity to reconnect with familiar faces. It was especially pleasing to see graduates from the 1940s at the party. We were also privileged to have guest speaker and alumnus, theoretician Professor Helen Quinn AO join us for the event. She completed her undergraduate degree at Melbourne before moving to Standford.

DONATIONS and SUPPORT

The School greatly acknowledges the support of the Mr Andrew Brooks of the Colonial Foundation. They have generously provided $360,000 over 3 years to expand Dr Roger Rassool's Outreach activities.

The School continues to value the donations to the University made by Misses Betty and Jean Laby whose late father, Professor Thomas Laby, was the Professor of Natural Philosophy (Physics) from 1915-1944.

The School of Physics also acknowledges the support of the Pierce Bequest, set up by philanthropist Arthur Albert Howard Pierce. The annual funds worth $30,000 have been invested

in computer equipment destined for teaching undergraduate and postgraduate purposes.

In 1984, Emeritus Professor JF Ward of Townsville, set up a trust in memory of his great-aunt Edith Ward, who in 1896 was among the first 55 women to graduate at The University of Melbourne. Such support also commemorates the association over a span of four generations of the Ward Family with the School of Physics.

Colin A Ramm was appointed a 'Professor of the University' in 1972, with a Personal Chair in the Department of Physics 1982 - 1986. In 1987 he became an Honorary Professor, and Professor Emeritus in 1999. We value the contributions of the Ramm family in support of the scholarship prizes in their name.
