Professor Esra Sorguven from the Thermo-Fluid Mechanics Research Centre (TFMRC) recently gave an invited lecture during the HAPP one-day conference on “Order and Chaos”. The event was arranged by the St Cross Centre for the History and Philosophy of Physics and took place at the Mathematical Institute in Oxford.

Esra’s talk explored Examples of Entropy which covered applications ranging from Physics to Nature. You can watch the full lecture here.

About the conference

Order and chaos have been fundamental concepts in human thought from the earliest times. The ancient astronomers devised systems to explain the ostensibly chaotic motions of the stars and planets, later culminating in the apparently deterministic laws of Newton' theory of gravity. However, Poincaré's study of the three-body problem showed that chaos would invariably result from the inevitable uncertainty of the initial conditions. Building on this, Lorenz derived the Butterfly Effect whereby seemingly trivial, remote occurrences can result in huge chaotic outcomes.

The expression of the Second Law of Thermodynamics, most notably by Clausius and Kelvin, with the concept of entropy as well as Boltzmann's work in statistical mechanics demonstrated the inevitable increase in the disorder in physical systems. Most recently work on the quantum theory of chaos, in between order and disorder, promises to impact the development of quantum technologies including computing. This conference will examine the evolution of the theories of order and chaos across the centuries and their prospects for future advances.

The St Cross Centre for the History and Philosophy of Physics (HAPP) has been established in the first instance to bring together the community of scholars in the history and philosophy of physics in Oxford, the United Kingdom and beyond.
