New Chief Scientist appointed, Dirac Medal awarded, and Hidden Physicist discovered

Welcome to the final bulletin for 2020 and my final bulletin as AIP president. At our council meeting in February 2021 I will step aside as we welcome Professor Sven Rogge (UNSW Physics) as incoming president, and Professor Nicole Bell (UniMelb Physics) as vice president.

I wish them all the very best. I’m thrilled that the AIP has such a solid leadership team moving forward. Also, can I say what an honour and privilege it was to serve in this role. Thank you to everyone who has worked so hard over the past few years to make the AIP so strong.

Last month saw some significant awards and appointments, not the least of which was the welcome news that former AIP president Dr Cathy Foley is set to become Australia’s next Chief Scientist. See our story below.

The AIP was also proud to be co-sponsor of this year’s Dirac Medal, which was presented to Professor Susan Scott from ANU’s Department of Quantum Science.

ANSTO’s new Centre for Accelerator Science has a new leader, Dr Ceri Brenner.

You’ll find more about her, Professor Scott and a slew of other physicists doing marvellous things in this issue.

You’ll also get to meet this month’s Hidden Physicist – Tasmania’s Nicola Ramm – and catch up on the latest physics research happening around the country.

Plus, there are some jobs to be found, and another story from the Australian Physicist vaults.

And a reminder that it’s time to renew your AIP membership. For a quick and easy way to do so, please go here.

Finally, this month’s picture was taken for a media release on making diamonds at room temperature. You’ll find the story below.

I wish you a relaxed and enjoyable holiday period, and sincerely hope that 2021 will be a calmer year for us all.

Meet Nicola Ramm, this month’s Hidden Physicist
#PhysicsGotMeHere

Name: Nicola Ramm

Employer: Institute of Mine Seismology, Tasmania

Job title and description: Geophysicist. I work for a company that provides monitoring of seismic activity within the mining industry for a range of purposes.

My role in the Applied Geophysics branch of the company is to implement projects which utilise ambient noise. These are the waves that occur constantly within the earth, caused by everything from mining machinery and nearby traffic to waves from the ocean. Ambient noise waves bounce around within the earth and sample the surrounding medium. This noise can then be harnessed to see changes in velocity properties of the surrounding rock or ground cover.

I have been involved in applying this technique for safety monitoring of tailings dams, which are structures where toxic mine waste is stored. These are often poorly built and insufficiently monitored, leading to a high number of failures, which can cause catastrophic loss of life and other environmental impacts.

I also work in applying ambient noise techniques to mineral exploration, where the deployment of small seismic sensors at surface can be used to create 3D mapping of the subsurface. This technique is much easier and less environmentally damaging than traditional mineral exploration approaches, such as drilling.

Through my career in geophysics, I have already been lucky enough to travel and be involved in a wide range of projects. I have undertaken surveys in northern Sweden and Nevada. Last year, I was able to present the research my team and I had been working on at several conferences in Perth, France and the AGU Fall meeting in San Francisco.

My career story so far:
I always enjoyed maths and physics and I enrolled in a Bachelor of Marine and Antarctic Science with a major in physics at the University of Tasmania in 2015. I then went on to complete my Honours in physics, looking at using microwave backscatter to measure the sea ice thickness in Antarctica.

I loved applying physics to real-world situations, and upon looking for work after University in 2018, I applied for the position with the Institute of Mine Seismology (IMS). I had no prior knowledge of geophysics, but my solid physics theory foundation has allowed me to adapt and learn the ‘geo’ aspect of my work on the go.

I had almost no knowledge of the mining industry before working at IMS, and it has been a really great opportunity to learn about the workings of such an important industry, which is often out of sight for the wider population. I have really enjoyed the new and diverse projects I get to be involved in, and seeing the ways in which my problem solving can be implemented into real-world solutions.

For ANSTO, UK’s loss is Australia’s gain

Dr Ceri Brenner has been appointed leader of the Australian Nuclear Science and Technology Organisation’s Centre for Accelerator Science.

Excitingly for the AIP Ceri made the decision to seek the ANSTO post after touring Australia in 2018 as that year’s AIP Women In Physics lecturer!

In a Twitter exchange last month Dr Brenner told AIP President Jodie Bradby that the 2018 trip, which involved visits to ANSTO and Lucas Heights, was her “stars in eyes moment”.

Dr Ceri Brenner, an accomplished physicist, innovator, and internationally recognised expert in industry applications of plasma-based accelerators, has been appointed leader of the Australian Nuclear Science and Technology Organisation’s Centre for Accelerator Science.

Dr Brenner is leaving her role as a group leader at the Central Laser Facility of the Science and Technology Facility Council in the UK to take up the position overseeing the accelerator science platform, which is home to accelerator science and engineering experts operating a suite of four ion accelerators across 17 beamlines.

FROM THE VAULT: stories from The Australian PhysicistThis month in 1977: The Great Melbourne Telescope 

The installation in 1869 of the great 42-inch reflecting telescope at the Melbourne Observatory can be said to mark the first attempt on this continent at what we would term ‘big science’. At the time of its installation it was exceeded in size only by Lord Rosse’s 72-inch reflector in Ireland, essentially a transit instrument which was, by comparison, relatively clumsy to handle. No other substantial telescope existed in the southern hemisphere. Although the subsequent history of the Great Melbourne Telescope, as it was known, was a rather unfortunate one, the events leading up to its design and eventual erection in Melbourne provide an interesting insight into nineteenth century astronomical aspirations.

Ancient star’s orbits prompt rethink on Milky Way evolution
 

Australian telescope and European satellite combine to reveal unexpected motions among the galaxy’s rarest objects.

Metal-poor stars—containing less than one-thousandth the amount of iron found in the Sun—are some of the Galaxy’s rarest objects. The study of these stars’ orbits has found that some of them travel in previously unpredicted patterns.

According to scientists, theories on how the Milky Way formed are set to be rewritten following discoveries about some of its oldest stars’ behavior.

In a study by the ARC Centre of Excellence for All-Sky Astrophysics in 3D (ASTRO 3D), scientists studied 475 Metal-poor stars. 11% of stars orbit in the almost flat plane that is the Milky Way’s disc.

Past studies have suggested that metal-poor stars were solely limited to the Galaxy’s halo and bulge, yet this study uncovered a huge number orbiting the disk itself.

Scientists produce diamonds in minutes at room temperature

Diamonds can now be produced in minutes – and at room temperature.

A study conducted by an international team of scientists from The Australian National University, RMIT University, the University of Sydney and the Oak Ridge National Laboratory and published in the journal Small reports that both Lonsdaleite and regular diamonds can form at normal room temperatures by just applying high pressures – equivalent to 640 African elephants on the tip of a ballet shoe.

“Natural diamonds are usually formed over billions of years, about 150 kilometres deep in the Earth where there are high pressures and temperatures above 1,000 degrees Celsius,”  Jodie Bradby, professor at The Australian National University and one of the authors of the study, said in a media statement.

Can we control where lightning strikes?

Pioneering laser technology could be used to tame lightning and control where it strikes the ground, according to an international team of scientists.

Dry lightning strikes ignited many of the devastating bushfires of Australia’s 2019-20 “black summer”, but if we could artificially control the path and direction of lightning, fire risk could be drastically reduced.

A new laser tractor beam technology, described in a paper in the journal Nature Communications, may be the answer.

In a laboratory experiment, the team used a laser beam to trap and heat microparticles of graphene in the air between two metallic plates. This created a heated channel that induced lightning and allowed the electrical discharge to flow towards a pre-defined target.
