My year of buying almost nothing saved me thousands of dollars – but also taught me valuable lessons as a teacher, including about the benefits of failure.
When politicians use selected modelling results to justify their decisions on contentious projects like Melbourne’s North East Link, the credibility of transport models suffers by association.
Transport modelling has been tarnished by its use to justify the predetermined projects politicians favour. But, if used more transparently, it's a valuable tool for planning our future cities.
You can help stop the spread of ‘fake news’ online.
We used game theory to show you only need a small amount of fake news to disrupt any group discussion. But we also found a way you can fight back.
Whether it’s birds in a flock or drivers in traffic, agent-based modelling can describe complex phenomena by applying a simple set of rules to each individual’s behaviour.
By identifying and applying the key rules governing the behaviour of each individual, agent-based modelling offers insights into complex phenomena like traffic jams and flocking.
A 2018 pilot project between the Public Health Agency of Canada and Advanced Symbolics will use social media posts as a resource to predict regional suicide rates.
From predicting suicide risk to chatbot therapy, artificial intelligence is all the rage in suicide prevention. The question is, can it really work?
Capetonians wait to fill up water containers.
There are measures in place to manage Day Zero and beyond. Models show that these will not work.
Is it just surfing or is it signal processing?
All earthly and celestial things emit signals. The science of signal processing, born in the 19th Century and now greatly advanced thanks to computers, allows us to better understand them.
If more people live in the Adelaide Hills, they are more likely to be exposed to bushfires.
What decisions can we make today to reduce the future risk of hazards like floods and fire? Particularly in a time of climate change, modelling various plausible futures helps us plan for uncertainty.
Banning retouched images of models is a step forward, but the fashion industry's attitude to beauty needs to change.
People currently speak 7,000 languages around the globe.
There's little research into origins of the geographic patterns of language diversity. A new model exploring processes that shaped Australia's language diversity provides a template for investigators.
There are some great uses.
Maths is often a quiet contributor to problems in subjects like biology.

New study suggests a 64km diameter body travelling at 15km per second created the Orientale Basin on the moon.
The Titan Supercomputer, in the US, has allowed scientists to study ice formation on wind turbines at a molecular level.

Developing new technologies requires time-consuming, expensive and even dangerous experiments. But now we can carry out many experiments entirely on computers using modelling.
The economic uncertainty index shows there is still a need for strong policy responses to events that shock the economy.
The Reserve Bank of Australia has created a new index for uncertainty in the Australian economy based on news, financial indicators and economic variables.
The original antigenic sin has made fighting diseases really difficult.
Innovative initiative aims to inspire pupils on the continent to take up careers in science.
Your bones are cleverer, and more complex, than you might think.
The network of bone cells inside your skeleton rivals your brain in terms of complexity.
Every living organism needs the same five basic processes – and we can now model ecosystems on them.
It may sound overly simple, but just five processes can define us as animals: eating, metabolism, reproduction, dispersal and death. They might not seem like much, but, thanks to a mathematical model from…
From geysers to tectonic plate movements, corn syrup has the answers.
A decade ago, with Ross Griffiths of the Australian National University, we aimed to build a 4D model which could replicate the Earth’s tectonic processes. Now, our research has helped us understand how…
The Blue Marble: who’s pulling the strings here?
It seems somewhat eccentric if not a little absurd to suggest that a planet is a living thing. Earth has life on it, but it’s not a biological organism. Any theory or argument which concludes that the…
All humans navigate life using models - most of us just don’t realise.
Planning for our future can be a heated topic, as the many people affected may have competing or conflicting objectives. The tension, frustration and bewilderment that can accompany such an exercise can…
