Constantin Piron
Constantin Piron (1932, Paris - 9 May 2012, Lausanne) was a Belgian physicist who worked for most of his career in Switzerland. In 1963 Piron earned his doctor of science degree from the University of Lausanne under the direction of Ernst Stueckelberg and Josef-Maria Jauch with a thesis on quantum logic, "Axiomatique quantique". He developed Jauch's methods (called the Geneva approach) for the foundations of quantum mechanics. Piron's Theorem (1964) is a famous representation theorem for quantum lattices. He was appointed assistant professor in the physics department of the University of Geneva in 1969 and professor ordinarius in 1974. He retired in 2000.

University Of Lausanne
The University of Lausanne (UNIL; french: links=no, Université de Lausanne) in Lausanne, Switzerland was founded in 1537 as a school of Protestant theology, before being made a university in 1890. The university is the second oldest in Switzerland, and one of the oldest universities in the world to be in continuous operation. As of fall 2017, about 15,000 students and 3,300 employees studied and worked at the university. Approximately 1,500 international students attend the university (120 nationalities), which has a wide curriculum including exchange programs with other universities. Since 2005, the university follows the requirements of the Bologna process. The 2011 Times Higher Education World University Rankings ranked the University of Lausanne 116th globally. The CWTS Leiden Ranking 2015 ranks the University of Lausanne 11th in Europe and 41st globally, out of 750 universities. Together with the École polytechnique fédérale de Lausanne (EPFL) the university forms a ...

Ernst Stueckelberg
Ernst Carl Gerlach Stueckelberg (baptised as Johann Melchior Ernst Karl Gerlach Stückelberg, full name after 1911: Baron Ernst Carl Gerlach Stueckelberg von Breidenbach zu Breidenstein und Melsbach; 1 February 1905 – 4 September 1984) was a Swiss mathematician and physicist, regarded as one of the most eminent physicists of the 20th century. Despite making key advances in theoretical physics, including the exchange particle model of fundamental forces, causal S-matrix theory, and the renormalization group, his idiosyncratic style and publication in minor journals led to his work not being widely recognized until the mid-1990s. Early life Born into a semi-aristocratic family in Basel in 1905, Stueckelberg's father was a lawyer, and his paternal grandfather a distinguished Swiss artist. A highly gifted school student, Stueckelberg initially began a physics degree at the University of Basel in 1923. Career While still a student, Stueckelberg was invited by the distinguished qua ...

Josef-Maria Jauch
Josef Maria Jauch (September 20, 1914 in Lucerne – August 30, 1974 in Geneva) was a Swiss/American theoretical physicist, known for his work on quantum electrodynamics and on the foundations of quantum theory, and leader of the "Geneva School" of mathematical physics. Biography Early life Jauch was born on 20 September 1914 in Lucerne, Switzerland, the son of Josef Alois Jauch (a telegraph operator) and Emma Laura Rosa Jauch (née Conti). He had two older siblings: Adelheid Jauch and Emil Josef Karl Jauch. After his mother died in 1916, his father remarried, and a half-sister was born: Margrit Jauch (Fuchs). At the age of twelve he became fascinated with a fact he found stated in a popular astronomy book, that an orbiting body with period T, if brought to a stop, would fall into the central mass in time T/\sqrt, which he showed could be derived from Kepler's law. Jauch was also interested in music, studying the violin from age twelve with his father, and then professionally ...

Quantum Logic
In the mathematical study of logic and the physical analysis of quantum foundations, quantum logic is a set of rules for manipulation of propositions inspired by the structure of quantum theory. The field takes as its starting point an observation of Garrett Birkhoff and John von Neumann, that the structure of experimental tests in classical mechanics forms a Boolean algebra, but the structure of experimental tests in quantum mechanics forms a much more complicated structure. Quantum logic has been proposed as the correct logic for propositional inference generally, most notably by the philosopher Hilary Putnam, at least at one point in his career. This thesis was an important ingredient in Putnam's 1968 paper " Is Logic Empirical?" in which he analysed the epistemological status of the rules of propositional logic. Modern philosophers reject quantum logic as a basis for reasoning, because it lacks a material conditional; a common alternative is the system of linear logi ...

Quantum Mechanics
Quantum mechanics is a fundamental theory in physics that provides a description of the physical properties of nature at the scale of atoms and subatomic particles. It is the foundation of all quantum physics including quantum chemistry, quantum field theory, quantum technology, and quantum information science. Classical physics, the collection of theories that existed before the advent of quantum mechanics, describes many aspects of nature at an ordinary (macroscopic) scale, but is not sufficient for describing them at small (atomic and subatomic) scales. Most theories in classical physics can be derived from quantum mechanics as an approximation valid at large (macroscopic) scale. Quantum mechanics differs from classical physics in that energy, momentum, angular momentum, and other quantities of a bound system are restricted to discrete values ( quantization); objects have characteristics of both particles and waves (wave–particle duality); and there are limits to ...

Helvetica Physica Acta
Helvetica (originally Neue Haas Grotesk) is a widely used sans-serif typeface developed in 1957 by Swiss typeface designer Max Miedinger and Eduard Hoffmann. Helvetica is a neo-grotesque design, one influenced by the famous 19th century (1890s) typeface Akzidenz-Grotesk and other German and Swiss designs. Its use became a hallmark of the International Typographic Style that emerged from the work of Swiss designers in the 1950s and '60s, becoming one of the most popular typefaces of the mid-20th century. Over the years, a wide range of variants have been released in different weights, widths, and sizes, as well as matching designs for a range of non-Latin alphabets. Notable features of Helvetica as originally designed include a high x-height, the termination of strokes on horizontal or vertical lines and an unusually tight spacing between letters, which combine to give it a dense, solid appearance. Developed by the ''Haas'sche Schriftgiesserei'' (Haas Type Foundry) of Münchens ...

University Of Geneva
The University of Geneva (French: ''Université de Genève'') is a public research university located in Geneva, Switzerland. It was founded in 1559 by John Calvin as a theological seminary. It remained focused on theology until the 17th century, when it became a center for enlightenment scholarship. Today, it is the third largest university in Switzerland by number of students. In 1873, it dropped its religious affiliations and became officially secular. In 2009, the University of Geneva celebrated the 450th anniversary of its founding. Almost 40% of the students come from foreign countries. The university holds and actively pursues teaching, research, and community service as its primary objectives. In 2016, it was ranked 53rd worldwide by the Shanghai Academic Ranking of World Universities, 89th by the QS World University Rankings, and 131st in the Times Higher Education World University Ranking. UNIGE is a member of the League of European Research Universities (includi ...
