A True Polymath

This book contains papers honouring Professor Francisco Doria. It spun out of a meeting in Rio de Janeiro, Brazil, in 2018, gathering researchers who have worked directly with Doria or his ideas to celebrate his 70th birthday. Doria's work is genuinely multidisciplinary, ranging from physics to economy, passing through philosophy, computer science, and mathematics foundations. This broad interdisciplinary impact is reflected in this book's range of topics. The quality of Doria's work and influence is also reflected in this volume, as it contains numerous influential thinkers and scholars, such as Newton da Costa (a long-term collaborator of Doria), Gregory Chaitin, Itala D'Ottaviano, Marcelo Gleiser, Bruno Scarpellini, and many more. It is notable to mention that, in addition to mathematics and physics, his areas of formal training, Doria has extensive interests in a variety of topics. Those who were able to have a quick conversation with him know of his vast knowledge of philosophy (both continental and analytical), art, literature, history, archeology, linguistics, and genealogy. Indeed, he has also published in some of those areas. He is truly a polymath.
