The Physics of Wall Street
A Brief History of Predicting the Unpredictable
1 of 1 copy available
After the economic meltdown of 2008, Warren Buffett famously warned, “beware of geeks bearing formulas.” But while many of the mathematicians and software engineers on Wall Street failed when their abstractions turned ugly in practice, a special breed of physicists has a much deeper history of revolutionizing finance. Taking us from fin-de-siècle Paris to Rat Pack–era Las Vegas, from wartime government labs to Yippie communes on the Pacific coast, James Owen Weatherall shows how physicists successfully brought their science to bear on some of the thorniest problems in economics, from options pricing to bubbles.
The crisis was partly a failure of mathematical modeling. But even more, it was a failure of some very sophisticated financial institutions to think like physicists. Models—whether in science or finance—have limitations; they break down under certain conditions. And in 2008, sophisticated models fell into the hands of people who didn’t understand their purpose, and didn’t care. It was a catastrophic misuse of science. The solution, however, is not to give up on models; it’s to make them better.
This book reveals the people and ideas on the cusp of a new era in finance, from a geophysicist using a model designed for earthquakes to predict a massive stock market crash to a physicist-run hedge fund earning 2,478.6% over the course of the 1990s. Weatherall shows how an obscure idea from quantum theory might soon be used to create a far more accurate Consumer Price Index. The Physics of Wall Street will change how we think about our economic future.
“Fascinating history . . . Happily, the author has a gift for making complex concepts clear to lay readers.” —Booklist

UC-Irvine professor Weatherall looks at the role played by physicists and their ideas in financial markets, and argues persuasively that their contributions should be more widely used and recognized. Himself a physicist, philosopher, and mathematician, Weatherall suggests that the profession’s essential contribution to finance is to develop models of how financial markets operate using insights from science. Answering the concerns of skeptics like Warren Buffett, he cautions that physicists approach their models simply as useful tools, and that the 2008 Wall Street crisis partly reflects financiers’ difficulty in appreciating that models offer only a simplified representation of reality. Though this book is hardly beach reading, even laymen can enjoy Weatherall’s sketches of eccentric theoreticians and his examples of unexpected patterns gleaned from such unrelated fields as the study of migratory salmon and the discovery of nylon. Weatherall also adeptly simplifies information for the uninitiated, for example, illustrating chaos theory by discussing the behavior of gas particles and ants. Finally, Weatherall acknowledges that no single unified law can fully cover the ever-evolving nature of markets. While all attempts to divine the future smack a little of the Delphic oracle, anyone interested in how markets work will appreciate this serious hypothesis.
