Robert May, Former UK Chief Scientist and Chaos Theory Pioneer, Dies Aged 84

Pioneering Australian scientist Robert May, whose work in biology led to the development of chaos theory, has died at age 84. The Guardian reports: Known as one of Australia’s most accomplished scientists, he served as the chief scientific adviser to the United Kingdom, was president of the Royal Society, and was made a lord in 2001. Born in Sydney on January 8, 1938, May’s work was influential in biology, zoology, epidemiology, physics and public policy. More recently, he applied scientific principles to economics and modeled the cause of the 2008 global financial crisis. On Wednesday, his friends and colleagues paid tribute to a man who they said was a gifted polymath and a “true giant” among scientists. Dr Benjamin Pope, an Australian astrophysicist and student at Oxford from 2013 to 2017, said May was a role model, and meeting him was a highlight of his university career. “I became aware of his achievements almost as soon as I learnt anything about physics in university,” Pope told Guardian Australia. “My first contact with computer programming was at the University of Sydney, in first year physics, where the example is to recreate Robert May’s experiment with the bifurcation diagram and the logistic map. “His bifurcation diagram is one of the iconic diagrams in physics,” he said. “[And] he made what was between three or four independent discoveries that lead to chaos theory. You might have heard of the butterfly effect … May’s is probably the other foundational, computational model of chaos.”
