High Quality Content by WIKIPEDIA articles! Hafnium is a chemical element with the symbol Hf and atomic number 72. A lustrous, silvery gray, tetravalent transition metal, hafnium chemically resembles zirconium and is found in zirconium minerals. Its existence was predicted by Dmitri Mendeleev in 1869. Hafnium was the penultimate stable isotope element to be discovered (rhenium was identified two years later). Halfnium was found by Dirk Coster and Georg von Hevesy in 1923 in Copenhagen, Denmark, and named Hafnia after the Latin name for "Copenhagen". ... Read more

Born in Santa Cruz de la Sierra, Bolivia, he was known in Hungary as Rózsa-Flores Eduardo or Rózsa György Eduardo. His wartime nickname in the Croatian War of Independence was Chico, which is also the title of a feature film about him. He was a founding member of the Hungarian Jewish Cultural Association, an Opus Dei member, the editor of the nationalist portal Jobbik.net and Vice-President of the Hungarian Islamic Community. Eduardo Rózsa-Flores was born in Santa Cruz de la Sierra, Bolivia. His father, György (Jorge) Obermayer Rózsa was a Hungarian painter, of Jewish descent, who left Hungary in 1948 and moved to Paris. In 1952 he went to Bolivia with a French ethnographic mission. He stayed on, lecturing art, and married Nelly Flores Arias, a Catalan immigrant and high school teacher. His father was a committed communist and moved the family to Chile to escape the Hugo Banzer dictatorship in 1972, but emigrated to Sweden in 1973 after Augusto Pinochet came to power. In 1974, they moved to Hungary. Rózsa-Flores attended secondary school in Budapest.

Yonath (born June 22, 1939) (Hebrew: , pronounced ) is an Israeli crystallographer best known for her pioneering work on the structure of the ribosome. She is the current director of the Helen and Milton A. Kimmelman Center for Biomolecular Structure and Assembly of the Weizmann Institute of Science. In 2009, she received the Nobel Prize in Chemistry along with Venkatraman Ramakrishnan and Thomas A. Steitz for her studies on the structure and function of the ribosome, becoming the first Israeli woman to win the Nobel Prize out of nine Israeli Nobel laureates, , the first woman from the Middle East to win a Nobel prize in the sciences, and the first woman in 45 years to win the Nobel Prize for Chemistry. However, she said herself that there was nothing special about a woman winning the Prize. Yonath was born in 1939 in the Geula quarter of Jerusalem. Her parents were Zionist Jews who immigrated to Palestine before the establishment of Israel and her father was a rabbi. They settled in Jerusalem and ran a grocery, but found it difficult to make ends meet. They lived in cramped quarters with several other families, and Yonath remembers "books" being the only thing she had to keep her occupied.Despite their poverty, her parents sent her to school in the upscale Beit Hakerem neighborhood to assure her a good education. When her father died at the age of 42, the family moved to Tel Aviv. Yonath was accepted to Tichon Hadash high school although her mother could not pay the tuition. She gave math lessons to students in return. As a youngster, she says she was inspired by the Polish-French sci...More: http://booksllc.net/?id=2050555 ... Read more

Il vit la plupart de sa vie en Suède mais vécut aussi en Autriche, au Danemark et en Allemagne. Hevesy a développé l'utilisation des isotopes radioactifs comme traceurs isotopiques servant aux études biologiques, par exemple dans la recherche du métabolisme des vivants. Hevesy nait à Budapest dans une famille juive aristocratique. Il est le plus jeune des cinq fils. Son père, Lajos vient de la famille Bischitz (du nom d'une ville de Bohême : Byšice) qui fut anoblie par l'empereur François-Joseph en 1895 sous le nom magyar de Hevesy. La grand-mère du savant, Johanna Bischitz de Heves, était célèbre pour ses activités philantropiques. Lajos, conseiller privé de la cour, se fait appeler au début Bischitz-Hevesy et depuis 1906 seulement Hevesy. La mère de George de Hevesy, Eugenia (Jenny) Schossberger provenait aussi d'une famille juive originaire de Moravie, anoblie depuis 1863.

Extrait : Svante August Arrhenius (né à Vik le 19 février 1859 - mort à Stockholm 2 octobre 1927) était un chimiste suédois qui a été pionnier dans de nombreux domaines. Il a reçu le prix Nobel de chimie en 1903. Son fils Olof Vilhelm Arrhenius a été un chimiste réputé en Suède. Son petit-fils Gustaf Olof Svante Arrhenius a également fait une carrière scientifique (océanographe, biogéochimiste, exobiologiste). Tous deux ont étudié et fait progresser des sujets étudiés ou défrichés par leur père et grand-père. S.A. Arrhenius est né en Suède à Vik (aussi orthographié Wik ou Wijk) près d'Uppsala, de Gustav Svante Arrhenius et Carolina Thunberg. Son père après avoir été géomètre à l'université d'Uppsala y a obtenu une place de superviseur. À l'âge de trois ans, le petit Arrhenius apprend à lire tout seul, et en regardant son père additionner des nombres dans son livre de compte, il devient rapidement un prodige en arithmétique, compétence qu'il a très vite pu accroître, disposant de masses de données pour étudier les lois et relations mathématiques. À l'âge de 8 ans, il entre dans l'école locale « de la cathédrale » et s'y distingue dans le domaine de la physique et des mathématiques.

Auszug: George Charles de Hevesy, Georg Karl von Hevesy, (1 August 1885 - 5 July 1966) was a Hungarian radiochemist and Nobel laureate, recognized in 1943 for his key role in the development of radioactive tracers to study chemical processes such as in the metabolism of animals. Hevesy György was born in Budapest, Hungary to a Roman Catholic family of Hungarian Jewish decent, the fifth of eight children from his wealthy parents Lajos (Louis) Bischitz and Eugenia (Jenny) Schossberger. George grew up in Budapest and graduated high school in 1903 from Piarista Gimnázium. The family's name in the 1904 was Hevesy-Bischitz, and Hevesy later changed his own. De Hevesy began his studies in chemistry at the University of Budapest for one year, and at the Technical University of Berlin for several months, but changed to the University of Freiburg. There he came in contact with Ludwig Gattermann. In 1906 he started his Ph.D. thesis with Georg Franz Julius Meyer, acquiring his doctorate in physics in 1908. In 1908 Hevesy got a position at the ETH. When Richard Lorenz left for the University of Frankfurt and Richard Willstätter tried to convince him to stay in Zurich he decided to go to the University of Karlsruhe to work with Carl Bosch. To learn new methods, de Hevesy joined Rutherford's laboratory at the University of Manchester in 1911 where he met and became friends with Niels Bohr. In 1923 de Hevesy co-discovered hafnium (72Hf) (Latin Hafnia for "Copenhagen", the home town of Niels Bohr), with Dirk Coster. Mendeleev's periodic table in 1869 put the chemical elements into a logical system, however there was missing a chemical element...http://booksllc.net/?l=de ... Read more
