Édouard Guillaume
Édouard Guillaume (1881–1959) was a Swiss physicist and patent examiner, notorious for his published papers attacking Albert Einstein's theory of special relativity. He is also noteworthy for his work on mathematical economics. Édouard Guillaume was the younger cousin of Charles Édouard Guillaume, who won the Nobel prize in physics in 1920. Both of the Guillaume cousins received doctorates in physics from the Zurich Polytechnique (ETH Zurich (colloquially) , former_name = eidgenössische polytechnische Schule , image = ETHZ.JPG , image_size = , established = , type = Public , budget = CHF 1.896 billion (2021) , rector = Günther Dissertori , president = Joël Mesot , ac ...). Édouard Guillaume (the younger cousin) worked at the Swiss patent office where Einstein worked from 1902 to 1909. Beginning in 1913 Guillaume began publishing in the ''Archives des Sciences Physiques et Naturelles'' papers arguing for a Lorentzian electrodynamics with a universal time. ...

Albert Einstein
Albert Einstein ( ; ; 14 March 1879 – 18 April 1955) was a German-born theoretical physicist, widely acknowledged to be one of the greatest and most influential physicists of all time. Einstein is best known for developing the theory of relativity, but he also made important contributions to the development of the theory of quantum mechanics. Relativity and quantum mechanics are the two pillars of modern physics. His mass–energy equivalence formula , which arises from relativity theory, has been dubbed "the world's most famous equation". His work is also known for its influence on the philosophy of science. He received the 1921 Nobel Prize in Physics "for his services to theoretical physics, and especially for his discovery of the law of the photoelectric effect", a pivotal step in the development of quantum theory. His intellectual achievements and originality resulted in "Einstein" becoming synonymous with "genius". In 1905, a year sometimes described as his ' ...

Theory Of Special Relativity
In physics, the special theory of relativity, or special relativity for short, is a scientific theory regarding the relationship between space and time. In Albert Einstein's original treatment, the theory is based on two postulates: # The laws of physics are invariant (that is, identical) in all inertial frames of reference (that is, frames of reference with no acceleration). # The speed of light in vacuum is the same for all observers, regardless of the motion of the light source or the observer. Origins and significance Special relativity was originally proposed by Albert Einstein in a paper published on 26 September 1905 titled "On the Electrodynamics of Moving Bodies".Albert Einstein (1905)''Zur Elektrodynamik bewegter Körper'', ''Annalen der Physik'' 17: 891; English translatioOn the Electrodynamics of Moving Bodiesby George Barker Jeffery and Wilfrid Perrett (1923); Another English translation On the Electrodynamics of Moving Bodies by Megh Nad Saha (1920).

Charles Édouard Guillaume
Charles Édouard Guillaume (15 February 1861, in Fleurier, Switzerland – 13 May 1938, in Sèvres, France) was a Swiss physicist who received the Nobel Prize in Physics in 1920 in recognition of the service he had rendered to precision measurements in physics by his discovery of anomalies in nickel steel alloys. In 1919, he gave the fifth Guthrie Lecture at the Institute of Physics in London with the title "The Anomaly of the Nickel-Steels". Personal life Charles-Edouard Guillaume was born in Fleurier, Switzerland, on February 15, 1861. Guillaume received his early education in Neuchâtel, and obtained a doctoral degree in Physics at ETH Zurich in 1883. Guillaume was married in 1888 to A.M. Taufflieb, with whom he had three children. He died on 13 May, 1938 at Sèvres aged 77. Scientific career Guillaume was head of the International Bureau of Weights and Measures.Gould, p.201. He also worked with Kristian Birkeland, serving at the Observatoire de Paris—Section de Meud ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

University Of Neuchâtel
The University of Neuchâtel (UniNE) is a French-speaking university based in Neuchâtel, Switzerland. The university has four faculties (schools) and more than a dozen institutes, including arts and human sciences, natural sciences, law and economics. The Faculty of Arts and Human Sciences, with 2,000 students, is the largest school of those that comprise the University of Neuchâtel. The university has an annual budget of CHF 144 million and an annual research fund of CHF 40 million. Approximately 4,000 students, including 600 PhD students attend the university, and more than 600 diplomas, licences, doctorates and certificates are awarded each year. The university has more than 1,100 employees. History The University of Neuchâtel superseded the Academy, which was created in 1838 by King Frederick William IV of Prussia, Prince of Neuchâtel. It awarded licentiate academic degrees in arts and in sciences. In 1848, the Grand Council decreed the closing of the Academy and in 1 ...

International Congress Of Mathematicians
The International Congress of Mathematicians (ICM) is the largest conference for the topic of mathematics. It meets once every four years, hosted by the International Mathematical Union (IMU). The Fields Medals, the Nevanlinna Prize (to be renamed as the IMU Abacus Medal), the Carl Friedrich Gauss Prize, Gauss Prize, and the Chern Medal are awarded during the congress's opening ceremony. Each congress is memorialized by a printed set of Proceedings recording academic papers based on invited talks intended to be relevant to current topics of general interest. Being List of International Congresses of Mathematicians Plenary and Invited Speakers, invited to talk at the ICM has been called "the equivalent ... of an induction to a hall of fame". History Felix Klein and Georg Cantor are credited with putting forward the idea of an international congress of mathematicians in the 1890s.A.

Patent Examiners
A patent examiner (or, historically, a patent clerk) is an employee, usually a civil servant with a scientific or engineering background, working at a patent office. Major employers of patent examiners are the European Patent Office (EPO), the United States Patent and Trademark Office (USPTO), the Japan Patent Office (JPO), and other patent offices around the world. Duties Patent examiners review patent applications to determine whether the invention(s) claimed in each of them should be granted a patent or whether the application should instead be refused. One of the most important tasks of a patent examiner is to review the disclosure in the application and to compare it to the prior art. This involves reading and understanding a patent application, searching the prior art (including prior patent applications and patents, scientific literature databases, etc.) to determine what contribution the invention makes over the prior art, and issuing office actions to explain to the applica ...
