Léon Rosenfeld
Léon Rosenfeld (; 14 August 1904 in Charleroi – 23 March 1974) was a Belgian physicist and a communist activist. Rosenfeld was born into a secular Jewish family. He was a polyglot who knew eight or nine languages and was fluent in at least five of them. Rosenfeld obtained a PhD at the University of Liège in 1926, and he was a close collaborator of the physicist Niels Bohr from 1930 until Bohr's death in 1962. Rosenfeld published in 1930 the first systematic Hamiltonian approach to Lagrangian models that possess a local gauge symmetry, which predates by two decades the work by Paul Dirac and Peter Bergmann. Rosenfeld contributed to a wide range of physics fields, from statistical physics and quantum field theory to astrophysics. Along with Frederik Belinfante, he derived the Belinfante–Rosenfeld stress–energy tensor. He also founded the journal ''Nuclear Physics'' and coined the term lepton. In 1933, Rosenfeld married Yvonne Cambresier, who was one of the first wo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Frederik Belinfante
Frederik Jozef Belinfante (6 January 1913 – 5 June 1991) was a Dutch physicist and a professor at Purdue University. He was a proponent of the hidden variable interpretation of quantum mechanics. Belinfante was born in the Hague and was a student of H. A. Kramers at Leiden University. His Ph.D. thesis, published in 1939, is called 'Theory of Heavy Quanta'. Belinfante emigrated to Vancouver in 1946 and became an associate professor at the University of British Columbia. Two years later, in 1948, he moved to the United States and became a professor at Purdue. There, he studied quantum theory and cosmology. While writing his Ph.D. thesis, Belinfante co-authored a paper with Wolfgang Pauli called 'On the statistical behaviour of known and unknown elementary particles' Along with Léon Rosenfeld, Belinfante derived the Belinfante–Rosenfeld stress–energy tensor. Belinfante's works include ''Measurement and Time Reversal in Objective Quantum Theory'' (1975) and ''Survey o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Jewish Physicists
Jews (, , ), or the Jewish people, are an ethnoreligious group and nation, originating from the Israelites of ancient Israel and Judah. They also traditionally adhere to Judaism. Jewish ethnicity, religion, and community are highly interrelated, as Judaism is their ethnic religion, though it is not practiced by all ethnic Jews. Despite this, religious Jews regard converts to Judaism as members of the Jewish nation, pursuant to the long-standing conversion process. The Israelites emerged from the pre-existing Canaanite peoples to establish Israel and Judah in the Southern Levant during the Iron Age. John Day (2005), ''In Search of Pre-Exilic Israel'', Bloomsbury Publishing, pp. 47.5 8'In this sense, the emergence of ancient Israel is viewed not as the cause of the demise of Canaanite culture but as its upshot'. Originally, Jews referred to the inhabitants of the kingdom of JudahCf. Marcus Jastrow's ''Dictionary of the Targumim, Talmud Babli, Talmud Yerushalmi and ...

Scientists From Charleroi
A scientist is a person who researches to advance knowledge in an area of the natural sciences. In classical antiquity, there was no real ancient analog of a modern scientist. Instead, philosophers engaged in the philosophical study of nature called natural philosophy, a precursor of natural science. Though Thales ( 624–545 BC) was arguably the first scientist for describing how cosmic events may be seen as natural, not necessarily caused by gods,Frank N. Magill''The Ancient World: Dictionary of World Biography'', Volume 1 Routledge, 2003 it was not until the 19th century that the term ''scientist'' came into regular use after it was coined by the theologian, philosopher, and historian of science William Whewell in 1833. History The roles of "scientists", and their predecessors before the emergence of modern scientific disciplines, have evolved considerably over time. Scientists of different eras (and before them, natural philosophers, mathematicians, natur ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Belgian Jews
The history of the Jews in Belgium goes back to the 1st century CE until today.
