[email protected] NOV–DEC 2011 | 48(6) AUSTRALIAN PHYSICS 163 EDITORIAL Australian Institute of Physics Nobel Prize AIP website: www.aip.org.au for Physics AIP Executive President Dr Marc Duldig In the 1990s two teams, one led by [email protected] Brian Schmidt (ANU) and the other Vice President Dr Robert Robinson [email protected] by Saul Perlmutter (U. California), Secretary Dr Andrew Greentree [email protected] raced each other to find evidence Treasurer Dr Judith Pollard [email protected] that the expansion of the Universe Registrar A/Prof Bob Loss is slowing down because of the [email protected] effects of gravity. To the astonishment Immediate Past President A/Prof Brian James of both teams, they found exactly [email protected] the opposite – the expansion is accelerating, a profound discovery Special Projects Officers Dr John Humble that has been rewarded with this year’s Nobel Prize for Physics. [email protected] While Adam Riess (Johns Hopkins) was a member of the Schmidt Dr Olivia Samardzic group, it is well worth noting that two prominent members of the [email protected] Perlmutter group were the Australian astronomers Brian Boyle (CSIRO) and Warwick Couch (Swinburne University of Technology), AIP ACT Branch Chair Dr Anna Wilson so Australia can rightly claim a significant share of the discovery. [email protected] Although Australia has won more than its fair share of Nobel Secretary Joe Hope Prizes in Medicine, it has been a long time between drinks for [email protected] Physics. The only other occasion Australia can lay claim to the prize was the award in 1915 to father and son William and Lawrence AIP NSW Branch Chair Dr Graeme Melville [email protected] Bragg for their development of X-ray crystallography. Secretary Dr Frederick Osman There are some interesting parallels between the two prizes. [email protected] William came from England to take up a chair at the University of Adelaide. He married, raised a family and eventually the family AIP QLD Branch returned to England. William and Lawrence carried out the research Chair Dr Joel Corney [email protected] that led to their Nobel Prize on English soil. In contrast, Brian Secretary Dr Till Weinhold [email protected] Schmidt was born in the US and moved to the ANU in 1995. The research that led to his Nobel Prize was carried out on Australian AIP SA Branch soil. Chair Dr Scott Foster Congratulations again to Brian! [email protected] Secretary Dr Laurence Campbell [email protected] Until the Nobel announcement our cover story was to have been the article on manned spaceflight by Jonathan Nally on page 181. If AIP TAS Branch you are a regular listener to Robyn Williams’ Science Show, you will Chair Dr Elizabeth Chelkowska be aware of the excellent segments that Jonathan presents on [email protected] astronomy and space science.

AIP VIC Branch At the beginning of this year we set ourselves the goal of getting Chair Dr Andrew Stevenson [email protected] the magazine back on schedule by the end of the year. I’m pleased to Secretary Dr Mark Boland [email protected] note that we have achieved that goal, but only because of the hard work of our production team. I would like especially to thank our AIP WA Branch Chair A/Prof Marjan Zadnik [email protected] Assistant Editor Akin Budi, Guy Nolch at Control Publications, Secretary Dr Andrea Biondo [email protected] Rod Johnson and Ray Leung at Pinnacle Print Group, Che Giblin at MailPro, and Kim O’Dea at Waldron Smith Management.

It is the largest physics-based research activity by some measure with over 140 academics during 2010. RSPE maintains excellence in education and training standards and ensures a quality educational experience for all our students. We continue to develop our staff to their full potential whilst ensuring that staff skills are matched to priority directions, and implement appropriate succession planning to replace key late career staff. It is the ability of the School to launch appropriately resourced research efforts built around outstanding staff in a number of important areas of national significance, the unique and integrated research infrastructure and the interdisciplinary collaboration with colleagues across the ANU, nationally and internationally, that distinguish the School’s research effort and capacity. Grant successes during 2010 from the Australian Research Council included two new Centre of Excellence nodes, 19 discovery projects, nine Future Fellowships, two linkage projects and one linkage infrastructure Equipment and Facility (LIEF). The School is also involved in four externally-led LIEF grants, with some of the equipment being located at the School. Along with the award of five super science fellowships, and other grant successes of note were the award of an Australian Space Research Program from the Department of Innovation, Industry, Science and Research (DIISR), three from the Australian Nuclear Science and Technology Organisation (ANSTO) and eight from the Australian Synchrotron Company Ltd.

  • Innovation: Are We Getting It Right?
    AUSTRALIAN ACADEMY OF TECHNOLOGICAL SCIENCES AND ENGINEERING (ATSE) NUMBER 156 JUNE/JULY 2009 INNOVATION ARE WE GETTING IT RIGHT? Contributors discuss the Federal Budget impact on innovation and commercialisation, the focus on picking winners and how Australia can do it better MassMotion Limitless applications, definite answers Arup’s MassMotion modelling software brings 3-D models to life. The people in MassMotion models do more than add a sense of scale – they are intelligent and can retain information about their virtual environment, recognise congestion and consider alternate routes. Occupant flows can be identified, queuing effects measured and overall site efficiency gauged. Designers can optimise the safety and amenity of the built environment. Practical applications for MassMotion are limitless. For instance, Arup’s fire engineers improve evacuation design and safety by using MassMotion to predict crowd behaviour in emergencies. Arup’s software designers are using software engines and wireless controllers from computer gaming to create new ways to communicate complex designs to clients and contractors.
