I am a scientist, writer and broadcaster
who works to share how scientists think about the problems of everyday life. I have won an Ig Nobel Prize (and been voted by the Times newspaper as an “enemy of the people”) for showing how physics could be used to work out the best way to dunk a biscuit, and have written and broadcast extensively about the role of science in food, cooking and gastronomy. More recently, I have become increasingly concerned with the risks that the world now faces. I am especially concerned to communicate understanding of systemic risk, where societies, ecosystems and economies may suddenly change or collapse, slowly-developing catastrophic risks, where imperceptible changes can bring us to the brink of disaster before we realize it, and resilience in the face of risk.
I addressed the underlying problems in a trilogy of books: Rock, Paper, Scissors: Game Theory in Everyday Life (on the problem of cooperation); The Perfect Swarm: The Science of Complexity in Everyday Life (on making decisions in complex situations); and Crashes, Crises and Calamities: How We Can Use Science to Read the Early-Warning Signs (on predicting and dealing with sudden and sometimes catastrophic change in economies, nature and society).
Following publication of these books, I have become increasingly involved with the practical issue of how we can make the best decisions in this complex world. I have made keynote speeches, addressed expert workshops, published reports (such as “Preparing for Future Catastrophes”), written feature articles (such as “Governance of Slowly Developing Catastrophic Risks”, “How Scientists Can Communicate with Politicians“, and “Flying Blind Into the Future”), and made radio programmes (such as my “Ockham’s Razor” programme on Australian radio about the problems of social decision-making and, more recently Coping with Life’s Surprises (on minimising risk)). I also run active blogging, Twitter, and LinkedIn programmes.
My most recent keynote addresses have been for the Aon Benfield Hazards Conference Risk Re-imagined (Gold Coast, Australia, September 19-20 (2017)) and as a finalist in the world-wide Global Challenges New Shape competition (Stockholm, May 26-29 (2018)). I am currently working in collaboration with colleagues at the Future of Humanity Institute (Oxford) and MunichRe (Munich) to develop a fresh understanding of the concepts of resilience and cooperative global governance. I am also writing a chapter on ways to transform our economic thinking for a 2nd edition of The Kyoto Manifesto for Global Economics.
I originally trained as a physical chemist, working in the area of colloid and surface science, although I have since taken a degree in biology and an MA (with distinction) in philosophy. After nearly two decades working in food research in Australia (I am Australian by birth), with excursions into biomedical science, nano-technology, mining engineering, and philosophy, I moved to the UK, first in the anatomy department at University College London, and then in the Physics Department at the University of Bristol, where I still hold an honorary position, and which I combined for a while with teaching science communication at the University of the West of England.
I am now primarily a writer, speaker and broadcaster, working to make science accessible by showing how scientists think about the problems of everyday life
In the News
I have always been concerned to promote science as an integral part of our culture, and for a brief period held a British Association Media Fellowship, working with the (now defunct) BBC TV programme “Tomorrow’s World”, where I was responsible for running a competition to design and throw indoor boomerangs, including establishment of a new world record. My real break came, however, when I was asked by a publicity company to use science to work out the best way to dunk a biscuit. I tell the full story in my blog. Briefly, it led to the award of an IgNobel Prize, an invitation to write a book, and being voted by the Times newspaper as “an enemy of the people“.
Since then I have frequently made media headlines through light-hearted projects on how scientists tackle the questions of everyday life. Apart the physics of biscuit dunking, I have looked at the absorption of gravy by a roast dinner, the design of a perfect cheese sandwich, how best to stir porridge, and whether hot or cold water freezes faster in a bird bath in winter (demonstrated live on the BBC Radio 4 “Today” programme). I have twice been a speaker at London’s Royal Institution, and I am a regular speaker at the annual Oxford Symposium on Food and Cookery, where I am also a member of the advisory board.
All of these activities had the aim of showing how scientists think. I have now made many radio and television appearances worldwide with the same objective, including three series for BBC Radio 4 (The Science of DIY, The Sweet Spot and Redesigning the Body), and quite a few Ockham’s Razor and Science Show programmes for Radio National in Australia. I have also written numerous feature articles for U.K. newspapers, including two series for the Guardian on The Science of Cooking and a number of full-page feature articles for the Daily Mail.
My best-selling book How to Dunk a Doughnut: The Science of Everyday Life (2002) was translated into eleven languages, and resulted in my election as “Science Writer of the Year” by the American Institute of Physics.
This was followed by Weighing the Soul: The Evolution of Scientific Ideas (2004), which was concerned with showing how science actually works (although one bookshop misinterpreted the title and put it in the religious section!), and then with a trilogy about the role of science in addressing the major problems that we now face: Rock, Paper, Scissors: Game Theory in Everyday Life (2008) (on the problem of cooperation); The Perfect Swarm: The Science of Complexity in Everyday Life (2009) (on making decisions in complex situations); and Crashes, Crises and Calamities: How We Can Use Science to Read the Early-Warning Signs (2011) (on predicting and dealing with sudden and sometimes catastrophic change in economies, nature and society).
