Paul Neményi
Paul Felix Neményi (June 5, 1895March 1, 1952) was a Hungarian mathematician and physicist who specialized in continuum mechanics. He was known for using what he called the inverse or semi-inverse approach, which applied vector field analysis, to obtain numerous exact solutions of the nonlinear equations of gas dynamics, many of them representing rotational flows of nonuniform total energy. His work applied geometrical solutions to fluid dynamics. In continuum mechanics, "Neményi's theorem" proves that, given any net of isothermal curves, there exists a five parameter family of plane stress systems for which these curves are stress trajectories. Neményi's five constant theory for the determination of stress trajectories in plane elastic systems was subsequently proven by later mathematicians. He was the father of the statistician Peter Nemenyi and the putative father of former World Chess Champion Bobby Fischer. Biography Family Neményi was born to a wealthy Hungarian ...

Theodore Von Kármán
Theodore von Kármán ( , May 11, 1881May 6, 1963) was a Hungarian-American mathematician, aerospace engineer, and physicist who worked in aeronautics and astronautics. He was responsible for crucial advances in aerodynamics characterizing supersonic and hypersonic airflow. The human-defined threshold of outer space is named the " Kármán line" in recognition of his work. Kármán is regarded as an outstanding aerodynamic theoretician of the 20th century. Early life Theodore von Kármán was born into a Jewish family in Budapest, then part of Austria-Hungary, as Kármán Tódor, the son of Helene (Konn or Kohn, ) and . Among his ancestors were Rabbi Judah Loew ben Bezalel, who was said to be the creator of the Golem of Prague, and Rabbi , who wrote about Zohar. His father, Mór, was a well-known educator, who reformed the Hungarian school system and founded Minta Gymnasium in Budapest. He became an influential figure and became a commissioner of the Ministry of Educa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Finite Strain Theory
In continuum mechanics, the finite strain theory—also called large strain theory, or large deformation theory—deals with deformations in which strains and/or rotations are large enough to invalidate assumptions inherent in infinitesimal strain theory. In this case, the undeformed and deformed configurations of the continuum are significantly different, requiring a clear distinction between them. This is commonly the case with elastomers, plastically deforming materials and other fluids and biological soft tissue. Displacement field Deformation gradient tensor The deformation gradient tensor \mathbf F(\mathbf X,t) = F_ \mathbf e_j \otimes \mathbf I_K is related to both the reference and current configuration, as seen by the unit vectors \mathbf e_j and \mathbf I_K\,\!, therefore it is a '' two-point tensor''. Two types of deformation gradient tensor may be defined. Due to the assumption of continuity of \chi(\mathbf X,t)\,\!, \mathbf F has the inverse \mathbf H = \ma ...

Leó Szilárd
Leo Szilard (; ; born Leó Spitz; February 11, 1898 – May 30, 1964) was a Hungarian-born physicist, biologist and inventor who made numerous important discoveries in nuclear physics and the biological sciences. He conceived the nuclear chain reaction in 1933, and patented the idea in 1936. In late 1939 he wrote the letter for Albert Einstein's signature that resulted in the Manhattan Project that built the atomic bomb, and then in 1945 wrote the Szilard petition asking president Harry S. Truman to demonstrate the bomb without dropping it on civilians. According to György Marx, he was one of the Hungarian scientists known as The Martians. Szilard initially attended Palatine Joseph Technical University in Budapest, but his engineering studies were interrupted by service in the Austro-Hungarian Army during World War I. He left Hungary for Germany in 1919, enrolling at Technische Hochschule (Institute of Technology) in Berlin-Charlottenburg (now Technische Universität ...

George De Hevesy
George Charles de Hevesy (born György Bischitz; ; ; 1 August 1885 – 5 July 1966) was a Hungarian radiochemist and Nobel Prize in Chemistry 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. He also co-discovered the element hafnium. Biography Early years Hevesy György was born in Budapest, Hungary, to a wealthy and ennobled family of Hungarian-Jewish descent, the fifth of eight children to his parents Lajos Bischitz and Baroness Eugénia (Jenny) Schossberger (ennobled as "De Tornya"). Grandparents from both sides of the family had provided the presidents of the Jewish community of Pest. His parents converted to Roman Catholicism. George grew up in Budapest and graduated high school in 1903 from Piarist Gimnázium. The family's name in 1904 was Hevesy-Bischitz, and Hevesy later changed his own. De Hevesy began his studies in chemistry at the University of Budapest fo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
The Martians (scientists)
"The Martians" () were a group of prominent scientists (mostly, but not exclusively, physicists and mathematicians) of Hungarian Jewish descent who emigrated from Europe to the United States in the early half of the 20th century. P. 55 Leo Szilard, who jokingly suggested that Hungary was a front for aliens from Mars, used this term. In an answer to the question of why there is no evidence of intelligent life beyond Earth (called the Fermi paradox) despite the high probability of it existing, Szilárd responded: "They are already here among us they just call themselves Hungarians." This account is featured in György Marx's book ''The Voice of the Martians.'' Men included in the description Individuals named as members of ''The Martians'' group include: * Paul Erdős * Paul Halmos * Theodore von Kármán * John G. Kemeny * John von Neumann * George Pólya * Leó Szilárd * Edward Teller * Eugene Wigner * Franz Alexander * Peter Carl Goldmark * John Harsanyi * Peter Lax * ...

Matisse
Henri Émile Benoît Matisse (; 31 December 1869 – 3 November 1954) was a French visual arts, visual artist, known for both his use of colour and his fluid and original draughtsmanship. He was a drawing, draughtsman, printmaking, printmaker, and sculpture, sculptor, but is known primarily as a painter. Matisse is commonly regarded, along with Pablo Picasso, as one of the artists who best helped to define the revolutionary developments in the visual arts throughout the opening decades of the twentieth century, responsible for significant developments in painting and sculpture. The intense colourism of the works he painted between 1900 and 1905 brought him notoriety as one of the Fauvism, Fauves (French language, French for "wild beasts"). Many of his finest works were created in the decade or so after 1906, when he developed a rigorous style that emphasized flattened forms and decorative pattern. In 1917, he relocated to a suburb of Nice on the French Riviera, and the more re ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Wassily Kandinsky
Wassily Wassilyevich Kandinsky ( – 13 December 1944) was a Russian painter and art theorist. Kandinsky is generally credited as one of the pioneers of abstract art, abstraction in western art. Born in Moscow, he spent his childhood in Odessa, where he graduated from Grekov Odesa Art School, Odessa Art School. He enrolled at the University of Moscow, studying law and economics.

Klimt
Gustav Klimt (14 July 1862 – 6 February 1918) was an Austrian symbolist painter and a founding member of the Vienna Secession movement. His work helped define the Art Nouveau style in Europe. Klimt is known for his paintings, murals, sketches, and other objets d'art. Klimt's primary subject was the female body, and his works are marked by a frank eroticism. Amongst his figurative works, which include allegories and portraits, he painted landscapes. He is best known for '' The Kiss'' and ''Portrait of Adele Bloch-Bauer I.'' Among the artists of the Vienna Secession, Klimt was the most influenced by Japanese art and its methods. Early in his career, he was a successful painter of architectural decorations in a conventional manner. As he began to develop a more personal style, his work was the subject of controversy that culminated when the paintings he completed around 1900 for the ceiling of the Great Hall of the University of Vienna were criticised as pornographic. He subse ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
