PUBLIC LECTURE – 30 NOVEMBER 2017

Australian Institute of Physics – Tasmanian Branch

The Birth of Suns

Thursday 30 November 2017, 6.00-7.00 pm
Physics Lecture Theatre 1
University of Tasmania, Sandy Bay Campus, Hobart

 

Professor Mark Krumholz
Research School of Astronomy and Astrophysics, Australian National University

We’ve all learned that space is an empty vacuum, but it’s not. The space between the stars in our Galaxy contains, on average, about 1 atom per cubic centimeter. That’s a better vacuum than the best vacuum chamber we know how to make, but there are a lot of cubic centimeters in interstellar space, so the mass of all the gas between the stars adds up to about 10% of the mass of all the stars put together. The temperature of this gas varies enormously from place to place in the Galaxy, with temperatures as high as
millions of degrees and as low as a few degrees above absolute zero.

In the coldest regions of interstellar space, over millions of years gravity is able to draw the atoms together into immense clouds that ultimately condense into clusters of new stars. In our Galaxy, this process produces stars at a rate of about 1 new Sun per year, and the stars it makes are typically the size of the Sun or a little smaller. While we understand how this happens in general outline, many fundamental questions remain unanswered. What sets the rate at which stars form? What determines the final sizes of the individual stars? Where did our Sun form, and what happened to its siblings, the stars that formed out of the same cloud?

In this talk Mark will describe what we currently know, and what we don’t, about the birth of new Suns.

QLD Branch AGM 2017

Dear Members of the Australian Institute of Physics, Queensland Branch,

I would like to hereby invite you to join us at the upcoming Annual General Meeting and the two talks preceding and following the AGM.

 

The meeting will be held on Thursday the 26th of October from 17h (AGM~17:40h) onwards at Brian Wilson Chancellery, 61A- Senate Room, University of Queensland, St. Lucia. For catering purposes it would be appreciated if you could register your attendance by Tuesday the 24th of October via reply email or to aip_branchsecretary_qld@aip.org.au. Catering will involve pizza and cold drinks.

 

The talks will additionally be streamed online. If you are unable to attend in person, please feel free to join us online using the following link: https://uqz.zoom.us/j/7870078684.

Presentation and AGM details:
This year our meeting will be preceded by the AIP QLD Bragg Gold Medal Nominee Dr. Martin Ringbauer giving a presentation based from his PhD: “Experimental Metaphysics and the Nature of Reality” starting at 17:00h.


The AGM will follow Martin’s talk at approximately 17.40h.

After the AGM concludes, we are proud to present Dr. Helen Maynard-Casely (based at ANSTO) who will present us with this year’s AIP-QLD sponsored John Mainstone Youth Lecture Tour Talk entitled: “Journeying to the centres of the planets”.  Helen has presented this highly entertaining talk to hundreds secondary school students throughout Queensland, reaching from the urbanised south-east corner, to the tropical reaches of Cairns in the north. For online viewers we anticipate Helen’s talk to commence at 18.00h.
Please feel free to encourage non-members to attend the presentations as they are geared towards a general audience.

Part of our business for the AGM will be to elect the branch committee for 2018.
As per the AIP by-laws, the retiring committee has made nominations for next year’s committee, and these are listed below:

Till Weinhold (Chair) (UQ),
Joanna Turner  (Secretary) (USQ),
Joel Alroe (Vice-Chair) (QUT) ,
Igor Litvinyuk (Treasurer) (GU),
Scott Adamson (All Hallows),
Simon Critchley (Qld Health),
Austin Lund (UQ),
Nunzio Motta (QUT), and
Carolyn Brown (USQ).

 

Members may make further nominations, which need to be duly proposed and seconded and forwarded to the Secretary at least 24 hours before the AGM, directed to aip_branchsecretary_qld@aip.org.au. I look forward to seeing you on the 26th October!

Kind Regards
Joanna Turner
Secretary of the AIP QLD  

Public Lecture – 20 September 2017

2017 Alexander and Leicester McAulay Winter Lecture Series

Australian Institute of Physics – Tasmanian Branch

Giant Icebergs and the Future of the Antarctic Ice Sheet

Wednesday 20 September 2017, 8.00-9.00 pm
Physics Lecture Theatre 1
University of Tasmania, Sandy Bay Campus, Hobart

 

Dr Sue Cook
Antarctic Climate and Ecosystems Cooperative Research Centre

Events such as the 1 trillion-tonne iceberg which recently broke away from the Larsen C Ice Shelf capture headlines around the world. But what can these icebergs really tell us about the future of the Antarctic Ice Sheet? This lecture examines what we know about how icebergs form, how they are affected by climate change, and the implications for Antarctica’s future contributions to sea level rise.

Measuring Radiation Doses in 3-D with Polymer Gel Dosimeters

Tuesday 22 August 2017, 8.00-9.00 pm
Physics lecture Theatre 1
University of Tasmania, Sandy Bay Campus, Hobart

 

Professor Clive Baldock
University of Tasmania

Polymer gel dosimeters are fabricated from radiation sensitive chemicals which, upon irradiation, polymerize as a function of the absorbed radiation dose. These gel dosimeters, with the capacity to uniquely record clinical radiotherapy (radiation therapy) radiation dose distributions in three-dimensions (3D), have specific advantages when compared to one-dimensional dosimeters, such as ion chambers, and two-dimensional dosimeters, such as film. These advantages are particularly significant in dosimetry situations where steep dose gradients exist such as in intensity modulated radiation therapy (IMRT) and stereotactic radiosurgery. Polymer gel dosimeters also have specific advantages for brachytherapy dosimetry. Potential dosimetry applications include those for low-energy x-rays, high linear energy transfer (LET) and proton therapy, radionuclide and boron capture neutron therapy dosimetries. These 3D dosimeters are radiologically soft-tissue equivalent with properties that may be modified depending on the application. The 3D radiation dose distribution in polymer gel dosimeters may be imaged using magnetic resonance imaging (MRI), optical-computerized tomography (optical-CT), x-ray CT or ultrasound. The fundamental science underpinning polymer gel dosimetry will be reviewed along with the various evaluation techniques. Clinical dosimetry applications of polymer gel dosimetry will be presented.
