Ian C. Percival
Ian Colin Percival (born 1931) is a British theoretical physicist. He is the Emeritus Professor of the School of Physics and Astronomy at Queen Mary and Westfield College, University of London. He is one among the pioneers of quantum chaos and he is well known for his suggestion in the 1970s about the existence of a different type of spectra of quantum-mechanical systems due to classical chaos. Numerical explorations performed by other researchers clearly confirmed this idea later. In 1987, he came up with Franco Vivaldi algebraic number theory of quadratic number fields on the counting of periodic orbits in discrete chaotic dynamical systems ( the cats figure of Vladimir Arnold). Later on, he worked on the basics of quantum mechanics and the measurement process. Together with Walter Strunz he suggested the properties of the quantum foam at the Planck scale, (similar to the movement of particles due to Brownian motion) in the wave function of an atom-beam interference.Percival, Str ...

United Kingdom
The United Kingdom of Great Britain and Northern Ireland, commonly known as the United Kingdom (UK) or Britain, is a country in Europe, off the north-western coast of the continental mainland. It comprises England, Scotland, Wales and Northern Ireland. The United Kingdom includes the island of Great Britain, the north-eastern part of the island of Ireland, and many smaller islands within the British Isles. Northern Ireland shares a land border with the Republic of Ireland; otherwise, the United Kingdom is surrounded by the Atlantic Ocean, the North Sea, the English Channel, the Celtic Sea and the Irish Sea. The total area of the United Kingdom is , with an estimated 2020 population of more than 67 million people. The United Kingdom has evolved from a series of annexations, unions and separations of constituent countries over several hundred years. The Treaty of Union between the Kingdom of England (which included Wales, annexed in 1542) and the Kingdom of Scotland in 170 ...

Michael Berry (physicist)
Sir Michael Victor Berry, (born 14 March 1941), is a mathematical physicist at the University of Bristol, England. He is known for the Berry phase, a phenomenon observed e.g. in quantum mechanics and optics, as well as Berry connection and curvature. He specialises in semiclassical physics (asymptotic physics, quantum chaos), applied to wave phenomena in quantum mechanics and other areas such as optics. Education and early life Berry was brought up in a Jewish family and was the son of a London taxi driver and a dressmaker. Berry has a BSc in physics from the University of Exeter and a PhD from the University of St. Andrews. Career and research He has spent his whole career at the University of Bristol: research fellow, 1965–67; lecturer, 1967–74; reader, 1974–78; Professor of Physics, 1978–88; Royal Society Research Professor 1988–2006.

Math
Mathematics is an area of knowledge that includes the topics of numbers, formulas and related structures, shapes and the spaces in which they are contained, and quantities and their changes. These topics are represented in modern mathematics with the major subdisciplines of number theory, algebra, geometry, and analysis, respectively. There is no general consensus among mathematicians about a common definition for their academic discipline. Most mathematical activity involves the discovery of properties of abstract objects and the use of pure reason to prove them. These objects consist of either abstractions from nature orin modern mathematicsentities that are stipulated to have certain properties, called axioms. A ''proof'' consists of a succession of applications of deductive rules to already established results. These results include previously proved theorems, axioms, andin case of abstraction from naturesome basic properties that are considered true starting points of t ...
