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’.

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”.

Lasers And Super Exciting Research: It’s all in the name!

Tuesday 31 July 2018, 8.00-9.00 pm
Physics Lecture Theatre 1
University of Tasmania, Sandy Bay Campus, Hobart

 

Dr Ceri Brenner
Senior Application Development Scientist for High Power Lasers, UK Research and Innovation

Lasers are the greatest multi-taskers; from telecommunications to surgery, from space missions to cutting through steel, they’re used everywhere! But did you know that we are also using the most powerful lasers in the world to tackle some truly global challenges? We’ll explore how lasers are key to providing for our rapidly growing energy demands, how they will help spot and treat cancer and how they can be used for safe handling of nuclear waste.

Glitch – Investigating the densest matter in the universe: The 2016 glitch of the Vela pulsar

Thursday 7 June 2018, 8.00-9.00 pm
Physics Lecture Theatre 1
University of Tasmania, Sandy Bay Campus, Hobart

 

Jim Palfreyman
School of Natural Sciences, University of Tasmania

Pulsars are neutron stars that are the remnants of supernova explosions. They are highly dense and rotate rapidly, some with accuracy better than atomic clocks. The Vela pulsar famously “glitches” or speeds up in rotation roughly every three years. No glitch has ever been observed in-action with a radio telescope large enough to see individual pulses, until now. Some remarkable events occurred and these will be covered in detail. The presentation will be aimed at people who have a general interest in astronomy.

Shedding light on dark matter

A standard cosmological model has emerged over the last 30 or so years in which the matter content of the Universe is predominantly in the form of an exotic non-baryonic matter, quite unlike the ordinary matter of everyday experience. Uncovering the physical nature of this dark matter is one of the most pressing problems facing fundamental physics and cosmology in the 21st century.

Astronomical observations and modelling have played a key role in establishing what we think we know so far about the dark matter – the widely favoured Cold Dark Matter (CDM) model predicts successfully the large-scale distribution of galaxies in a cosmic web, and is consistent with our deepest observations of the early Universe, which show that galaxies, groups, and cluster are the product of mergers over the last 13 or so billion years of cosmic time. The CDM model is not without its problems, however, and, in particular, it is on the smallest galactic mass scales of dwarfs and satellites of the kind we find around the Milky Way that it has faced its most severe challenges.

I will review what the latest observations and numerical simulations are telling us about dark matter, and I will speculate on what we might learn in the coming years, especially as observation, theory, and experiment place more stringent limits on what the dark matter can be.

From Mad Scientists to Eco-Warriors: The changing image of scientists in fiction and film

Tuesday 10 April 2018, 8.00-9.00 pm
Physics Lecture Theatre 1
University of Tasmania, Sandy Bay Campus, Hobart

 

Adjunct Associate Professor Roslynn Haynes

For approximately 600 years, from 1380 to 1980, scientists or their predecessors, the alchemists and natural philosophers, fared ill at the hands of writers and, later, film makers.

They were obsessed to the point of madness, or evil, amoral, arrogant, impersonal, and inhuman. At best, they were well intentioned but blind to the dangers of forces they barely controlled. They were Faustus and Frankenstein, Jekyll and Moreau, Caligari and Strangelove – the scientists of film and fiction, cultural archetypes that reflected ancient fears of tampering with the unknown or unleashing the little-understood powers of nature.

Yet, since the 1990s, there has been a trend by novelists to present scientists as more complex, realistic figures, many honest and admirable even if confused as to their role. They are eco-warriors saving the planet, or medical researchers discovering new cures for humanity. However, in films, the mad, evil stereotype endures. What are the reasons for this disparity?  What do they teach us about the difficulties scientists have in convincing politicians and large sections of society of the need to take environmental pollution and climate change seriously?
