David Orrell - Four Way Interview

David Orrell is a writer of general audience books on science and economics, and an applied mathematician in his spare time. He has written books on topics including the science of prediction The Future of Everything, the relationship between science and aesthetics Truth or Beauty, and the problems with economics Economyths. His most recent book is Quantum Economics: The New Science of Money.

Why science (and economics)? 

I came into science through mathematics. My university offered undergraduate mathematics as part of an arts program, so you had to take half mathematics courses, but the rest could be from arts or sciences. So I combined subjects like set theory and topology with philosophy and art history. One thing I always liked about mathematics is that, being abstract, it can be applied to many different things and doesn’t lock you into a particular way of seeing the world. I became interested in economics after writing a book (The Future of Everything) about the science of prediction. I thought economics sounded completely crazy!

Why this book?

Quantum Economics is my attempt to make economics a little less crazy (though the title suggests otherwise!). The idea is that the money system shows the characteristic properties of a quantum system, including duality, indeterminacy, entanglement, and interference. It draws on areas such as quantum cognition, quantum finance, and quantum social science, where researchers use the quantum formalism to model human behaviour. But the main idea is that economics needs to focus more on the complex properties of money, which have been curiously neglected until now.

What’s next?

I would like to follow this quantum thread a little further, though not sure yet exactly where it will lead ... somewhere exciting I hope!

What’s exciting you at the moment?

Quantum ideas seem to be having something of a moment in the social sciences, which until now have been based on a firmly classical model of behaviour. I recently attended a workshop on quantum international relations at Ohio State University, which had an incredible mix of people from different backgrounds including political science, anthropology, physics, mathematics, and so on. As with my undergraduate education, it was a combination of sciences and humanities, so I felt right at home.

Beyond Weird - Philip Ball *****

It would be easy to think 'Surely we don't need another book on quantum physics.' There are loads of them. Anyone should be happy with The Quantum Age on applications and the basics, Cracking Quantum Physics for an illustrated introduction or In Search of Schrödinger's Cat for classic history of science coverage. Don't be fooled, though - because in Beyond Weird, Philip Ball has done something rare in my experience until Quantum Sense and Nonsense came along. It makes an attempt not to describe quantum physics, but to explain why it is the way it is.

Historically this has rarely happened. It's true that physicists have come up with various interpretations of quantum physics, but these are designed as technical mechanisms to bridge the gap between theory and the world as we see it, rather than explanations that would make sense to the ordinary reader.

Ball does not ignore the interpretations, though he clearly isn't happy with any of them. He seems to come clo…

The AI Delusion - Gary Smith *****

This is a very important little book ('little' isn't derogatory - it's just quite short and in a small format) - it gets to the heart of the problem with applying artificial intelligence techniques to large amounts of data and thinking that somehow this will result in wisdom.

Gary Smith as an economics professor who teaches statistics, understands numbers and, despite being a self-confessed computer addict, is well aware of the limitations of computer algorithms and big data. What he makes clear here is that we forget at our peril that computers do not understand the data that they process, and as a result are very susceptible to GIGO - garbage in, garbage out. Yet we are increasingly dependent on computer-made decisions coming out of black box algorithms which mine vast quantities of data to find correlations and use these to make predictions. What's wrong with this? We don't know how the algorithms are making their predictions - and the algorithms don't kn…

Five Photons - James Geach ****

It is generally acknowledged that Stephen Hawking's A Brief History of Time is one of the most common books to be bought but not read beyond the first few pages. If you are the kind of popular science reader who found Hawking hard going, you can stop now - Five Photons is not for you. If, on the other hand, you found A Brief History of Time a piece of cake and wished you could get into more depth without resorting to heavy mathematics or a tedious textbook style, Five Photons could be just up your street.

Astrophysicist James Geach starts of fairly gently with a chapter on the nature of light that mostly sets aside quantum physics, leading up to the observation that light is our vehicle for for stripping back the history of the universe to its earliest times (or, at least, the point where the universe became transparent). From here on, the five photons of the title take us on different journeys, from the oldest surviving light of the cosmic microwave background radiation to that fr…
