Tiny changes, like a butterfly’s wing flapping, can be amplified downstream in a chaotic system.

Part of the 2021 Nobel Prize in Physics was awarded for work modeling Earth’s climate using its chaotic, complex weather. To scientists, chaos lies in the gray zone between randomness and predictability.
Giorgio Parisi’s work has helped us tease predictable patterns from complexity.

The work of Italian physicist Giorgio Parisi has helped predict the unpredictable, from changes in the climate to the movements of flocks of starlings.
Why radical changes to society are needed if we are to escape environmental disaster.

We have long wondered why Earth has stayed habitable enough for life to evolve over billions of years.
Who could have predicted it would end like this?
The unexpected behaviour of even simple bots is only going to get more dramatic as AI scales up.
Will the robots come to control us?
He spends his days developing artificial intelligence systems. What about AI keeps him up at night?
South Korea’s subtly calibrated risk aversion in the face of outrageous North Korean aggression has kept the two countries from war.
An aggressive posture is one thing – but doing something about it is another, as countries factor in the costs and risks of aggression.
We need to find new ways to deal with the complexity of modern cities and make them better.
There are very few approaches that examine all aspects of the complexity of urban design and development. Ergonomics, human factors and sociotechnical systems methods offer a way forward.
It may look like a game of Lego, but it’s a serious exercise in innovation.
We’re living in a time of rapid transformation in terms of what’s required for a country’s workforce. Design thinking is one way to prepare graduates for these changing times.
Many of the debt recovery letters issued by Centrelink were the result of an intrinsically error prone system.

The Centrelink debt recovery system reminds us that many data systems are prone to error, and that’s built in to how they work.
A source of frustration.

The problems that cause us to be so frustrated we contemplate throwing a computer can be much more serious than a multimillionaire football coach having a minor tantrum on a Sunday afternoon.
You’re a mountaineer, right?
Complex systems, from TV shows to hospitals, have plenty of checks and procedures, so why do things still go wrong?
The climate is startlingly complex, as is the immune system.
Diverse threads of the vast interrogation of nature we call science are coming together in a rich and mutually informative intellectual tapestry.
Humanity is already existing well outside of its safe ecological space.
The Conversation organised a public question-and-answer session on Reddit in which James Dyke, a lecturer in Complex System Simulation, discussed planetary boundaries and whether global industrialised…
Muslim women pass bombed Christian shops in Nigeria: researchers and policymakers are developing complex views of organised violence.
In part 10 of the multi-disciplinary Millennium Project series, Alex Burns argues that we are getting more sophisticated in our approach to global threats and conflict. Global challenge 10: How can shared…
Overwhelmed: to live wisely in a world where complexity seems to be running rampant, we must first grasp what complexity is.

In part nine of our multi-disciplinary Millennium Project series, Cliff Hooker argues that to get any better at decision-making, we must first face up to our limitations. Global challenge 9: How can the…
