Grab a drink and a snack in a relaxed pub environment and listen to local physicists talking & laughing about their research.

Eight snappy physics acts, 8 minutes long from scientists working on astronomy, quantum physics, geophysics and more. Be prepared for comedy, songs, live experiments and heavy duty research.

MC Dr Phil Dooley from Phil Up On Science will keep you entertained and guide you through mind blowing concepts and brain boggling discoveries.

Sponsored by Australian Institute of Physics.

Presented by:
Local Physicists, MC Dr Phil Dooley

From childhood dreams of being an astronomer, Dr Phil Dooley progressed to a PhD in laser physics. After a stint as an IT trainer, he returned to science as a communicator, where he could talk about the fun stuff without the heavy-duty equations.

He regularly MCs Science in the Pub events, and has performed solo in shows and festivals from Adelaide to London, blending music, stand up comedy, fairytales and live science demos. He runs a YouTube channel, Phil Up On Science.

In has career he has taken on bored teenage school kids on physics excursions at University of Sydney; created digital content for the international fusion research organisation, JET; been schooled by a Reuters hack in the ANU media and written for prominent science publishers Nature, New Scientist and Cosmos Magazine.

Optical Tweezers ‘Demystified’

Assoc. Professor Bruce Wedding

University of South Australia

Since their invention 32 years ago, optical tweezers have become a powerful tool utilised in a wide variety of experiments in biology and physics. Optical tweezers use light to trap microscopic objects as small as 10 nm using radiation pressure from a focused laser beam. These trapped particles can then be manipulated and forces on the particles in the trap can be measured. The first designs of optical tweezers used high power lasers and expensive optical hardware. Recently however, simple and inexpensive apparatus for undergraduate laboratories can produce a single beam optical tweezer to trap micron-sized particles. Such a system in undergraduate laboratories and the resulting student engagement will be presented.

Interest in microfluidics is also a rapidly expanding area of research and the use of microchips as miniature chemical reactors, so called ‘Labs-on-a-Chip’ is increasingly common. Microfluidic channels are now complex and combine several functions on a single chip. Fluid flow details are important but relatively few experimental methods are available to probe the flow in a confined geometry. We can use optical trapping of a small dielectric particle to probe the fluid flow in microfluidic channels.

Rather than using the optical trap to position and release a particle for independent velocimetry measurement, we map the fluid flow by measuring the hydrodynamic force acting on a trapped particle. The flow rate of a dilute aqueous electrolyte flowing through a microchannel has been mapped using a small (1 µm diameter) silica particle. Such flow mapping is time efficient, reliable, and can be used in low-opacity suspensions flowing in microchannels of various geometries.

The Bronze Bragg medals and certificates will be presented at the lecture. The medal is awarded for highest achievement in Physics in 2018 in the SACE Stage 2 assessments, with certificates being for students who achieved a merit.

 The presentation and lecture will be held in the Napier 102 Lecture Theatre, Napier Building, 1st floor, University of Adelaide, North Terrace, north from Pulteney St., at 6.30pm. Members of the public are warmly invited to attend. We are obliged for security reasons to keep the front door of the building attended, so please arrive before 6.30pm. Bookings are not available. The doors must be closed if all seats are taken.

Title: Nonlinear optical properties of ZnO and ZnO-Au composite nanostructures for nanoscale UV emission

Abstract: This thesis investigates the nonlinear optical properties of ZnO and ZnO-Au composite nanostructures. For applications such as photodynamic therapy, it is desirable to use nanoparticles to generate localised UV emission while illuminating them with visible or infrared light. This is possible using nonlinear optical processes such as two photon absorption. Nonlinear optical processes however, are extremely weak, so this work investigates the potential of increasing the efficiency of two photon absorption in ZnO nanoparticles by coupling them to metal nanoparticles. Using new experimental methods, the two photon absorption and resulting UV emission from the nanoparticles are measured.

Physics is everywhere! – a journey from sub-atomic particles to the large-scale structure of the universe, where physics seeks to answer the most fundamental questions about reality. As we learn more, we can do more! Physics is everywhere in our world and underpins all our technologies. This year, Sean will discuss the important problems that all of us encounter every day: how do I teleport myself to school? What do I do when I find myself inside a black hole? Why is my time-machine not working? He will also talk about the superpowers that you can gain as a physicist, such as the ability to make accurate quantitative observations and predictive and interpretive mathematical models.  These powers mean that you can become very valuable and work in many industries such as fundamental physics research, economics and finance, space and aeronautics, healthcare and medicine, learning and teaching, electronics and computers, and so much more!

Good vibrations: Using ambient seismic signals to explore deep continents and distant oceans

Wednesday 28 November 2018, 6.00-7.00 pm (note early time)
Physics Lecture Theatre 1
University of Tasmania, Sandy Bay Campus, Hobart

 

Professor Anya Reading
School of Natural Sciences, University of Tasmania

Seismic ‘noise’, the background ambient signals recorded by seismic stations around the planet, can be utlised to infer the structure of the deep continents, the 3D architecture of the tectonic plates.  Ocean storms, at incredible distances, also transmit signals to seismic stations on land.  Archive seismic records can hence be used to investigate storms, and possible changes in storm patterns, over recent decades.  This presentation will survey the variety of seismic signals that we record, novel ways of extracting information from those signals and new insights on the continents and oceans that have arisen through making use of these ‘good vibrations’.

Abstract: When the term gamma radiation pops up, associations with radioactive hazards may arise. Do we have to be afraid of gamma radiation from space? Fortunately, we don’t have to be, because the Earth’s atmosphere protects us. Unfortunately, it also prevents us from directly observing this radiation from Earth. But it is in the nature of man to be curious to overcome these obstacles to investigate this vicious radiation from space. In 1961, a satellite was the first to detect gamma rays from space. At about the same time, the Cherenkov radiation was discovered – a radiation that is emitted when charged particles move through a medium at the speed of light. This led to a new technique, capable of measuring gamma rays from Earth, and paving the way for ground-based gamma-ray astronomy. However, it took 30 years until an appropriate experiment discovered the first gamma-ray emitting astrophysical source. Since then, hundreds of sources of Galactic and extragalactic origin have been discovered, and higher energies and sensitivities have been reached. The Cherenkov Telescope Array will exceed current experiments in a multitude of aspects: With more than 100 telescopes in 3 sizes at 2 locations equipped with state-of-the-art technologies, it will cover an area of 10 square kilometres on the ground, and it will provide a new view of the sky at energies of up to 300 TeV  – more than a 1000 billion times the energy of visible light. With its unprecedented capabilities, it will refine our knowledge tremendously and will mark the beginning of a new era of gamma-ray astronomy. Deeper insights into this field will be subject of this presentation.

Bio: Born around the time when Cherenkov telescopes made their first discovery, Sabrina Einecke is observing the extreme gamma-ray universe for more than 8 years. She took her first steps in gamma-ray astronomy with the ground-based experiments MAGIC, FACT and CTA. Completing research stays at the Columbia University in New York, she expanded her interests to the utilisation of machine learning approaches to combine a variety of multi-wavelength data to fully exploit the information that is available. This also led to her PhD thesis with the title “The Data Mining Guide to the Galaxy”. According to the German Physical Society, it has been among the best in Germany in 2017. After finishing her PhD studies in Germany, she moved to Australia and now supports the University of Adelaide as a postdoctoral research fellow. Her research focuses on Active Galactic Nuclei – the most extreme objects in the Universe – and data analysis using cutting-edge techniques from the fields of artificial intelligence and machine learning – crucial for handling the immense amount of data collected by next-generation experiments.

Why should I care about physics? From atoms to cancer therapy and more!

What a wonderful world! And how many different structures, from stars to human beings! We have learned about atoms, Higgs bosons, black holes and the Big Bang; we have internet, computers, satellites, GPS and so many amazing technologies! Who needs more?

But how do they work? One may think we should not care about the physics beyond technology; it is not our business how technology works! But this is not true! Amazing things happen if we try to understand the physics behind our technology: GPS works due to…Einstein; computers work due to…quantum mechanics; we can cure cancer with particle accelerators. But even more important, we can explore the Universe – inside and outside us – because we are curious beings, we are all born physicists!

The adventure of physics will last as long as humanity – we will never stop asking questions. Stay hungry, stay foolish? No! Stay curious. Albert Einstein once said: “I have no special talent. I am only passionately curious”.
