César Lattes
Cesare Mansueto Giulio Lattes (11 July 1924 – 8 March 2005), also known as César Lattes, was a Brazilian experimental physicist, one of the discoverers of the pion, a composite subatomic particle made of a quark and an antiquark. Life Lattes was born to a family of Italian immigrants in Curitiba, Paraná Brazil. He did his first studies there and also in São Paulo. He then went to the University of São Paulo, graduating in 1943, in mathematics and physics. He was part of an initial group of young Brazilian physicists who worked under European teachers such as Gleb Wataghin and Giuseppe Occhialini. Lattes was considered the most brilliant of those and was noted at a very young age as a bold researcher. His colleagues, who also became important Brazilian scientists, were Oscar Sala, Mário Schenberg, Roberto Salmeron, Marcelo Damy de Souza Santos and Jayme Tiomno. At the age of 25, he was one of the founders of the Brazilian Center for Physical Research (''Centro Brasileir ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Immigrant
Immigration is the international movement of people to a destination country of which they are not natives or where they do not possess citizenship in order to settle as permanent residents or naturalized citizens. Commuters, tourists, and other short-term stays in a destination country do not fall under the definition of immigration or migration; seasonal labour immigration is sometimes included, however. As for economic effects, research suggests that migration is beneficial both to the receiving and sending countries. Research, with few exceptions, finds that immigration on average has positive economic effects on the native population, but is mixed as to whether low-skilled immigration adversely affects low-skilled natives. Studies show that the elimination of barriers to migration would have profound effects on world GDP, with estimates of gains ranging between 67 and 147 percent for the scenarios in which 37 to 53 percent of the developing countries' workers migrate ...

Cecil Frank Powell
Cecil Frank Powell, FRS (5 December 1903 – 9 August 1969) was a British physicist, and Nobel Prize in Physics laureate for heading the team that developed the photographic method of studying nuclear processes and for the resulting discovery of the pion (pi-meson), a subatomic particle. Personal life Powell was born in Tonbridge, Kent, England, the son Frank and Elizabeth Caroline (née Bisacre) Powell. His father was a gunsmith. He was educated at a local primary school before gaining a scholarship to the Judd School, Tonbridge. Following this he attended Sidney Sussex College, Cambridge, graduating in 1925 in Natural Sciences. After completing his bachelor's degree he worked at the Cavendish Laboratory, Cambridge, under C.T.R. Wilson and Lord Rutherford, conducting research into condensation phenomena, and gaining his PhD in Physics in 1929. In 1932 Powell married Isobel Artner (1907-1995), and the couple had two daughters, Jane and Annie. Professional life In 1928 ...

Cosmic Rays
Cosmic rays are high-energy particles or clusters of particles (primarily represented by protons or atomic nuclei) that move through space at nearly the speed of light. They originate from the Sun, from outside of the Solar System in our own galaxy, and from distant galaxies. Upon impact with Earth's atmosphere, cosmic rays produce showers of secondary particles, some of which reach the surface, although the bulk is deflected off into space by the magnetosphere or the heliosphere. Cosmic rays were discovered by Victor Hess in 1912 in balloon experiments, for which he was awarded the 1936 Nobel Prize in Physics. Direct measurement of cosmic rays, especially at lower energies, has been possible since the launch of the first satellites in the late 1950s. Particle detectors similar to those used in nuclear and high-energy physics are used on satellites and space probes for research into cosmic rays. Data from the Fermi Space Telescope (2013) have been interpreted as evidence ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rio De Janeiro
Rio de Janeiro ( , , ; literally 'River of January'), or simply Rio, is the capital of the state of the same name, Brazil's third-most populous state, and the second-most populous city in Brazil, after São Paulo. Listed by the GaWC as a beta global city, Rio de Janeiro is the sixth-most populous city in the Americas. Part of the city has been designated as a World Heritage Site, named "Rio de Janeiro: Carioca Landscapes between the Mountain and the Sea", on 1 July 2012 as a Cultural Landscape. Founded in 1565 by the Portuguese, the city was initially the seat of the Captaincy of Rio de Janeiro, a domain of the Portuguese Empire. In 1763, it became the capital of the State of Brazil, a state of the Portuguese Empire. In 1808, when the Portuguese Royal Court moved to Brazil, Rio de Janeiro became the seat of the court of Queen Maria I of Portugal. She subsequently, under the leadership of her son the prince regent João VI of Portugal, raised Brazil to the dignity of a k ...

Marcelo Damy De Souza Santos
Marcelo Damy de Sousa Santos (July 14, 1914 – November 29, 2009) was a Brazilian physicist. Considered as one of the most important educators and researchers in physics in Brazil, along with Cesar Lattes, José Leite Lopes and Mario Schenberg, Damy was born in Campinas, São Paulo, in 1914, the son of Harald Egydio de Souza Santos a photographer, and Maria Luiza Damy de Souza Santos.

Mário Schenberg
Mário Schenberg (var. ''Mário Schönberg'', ''Mario Schonberg'', ''Mário Schoenberg''; July 2, 1914 – November 10, 1990) was a Brazilian electrical engineer, physicist, art critic and writer. Early life Schenberg was born in Recife, Brazil. His parents were Russian-Jews of German origin. From early on he showed remarkable ability for mathematics, enchanting himself with geometry, which had a strong influence on his works. Schenberg took the primary and secondary courses in Recife. Because of his family's financial limitations, he was not able to study in Europe. He then entered the Faculty of Engineering of Recife in 1931. Scientific work The Urca process Widely regarded as one of Brazil's most important theoretical physicists, Schenberg is best remembered for his contributions to astrophysics, particularly the theory of nuclear processes in the formation of supernova stars.

Giuseppe Paolo Stanislao "Beppo" Occhialini ForMemRS (; 5 December 1907 – 30 December 1993) was an Italian physicist who contributed to the discovery of the pion or pi-meson decay in 1947 with César Lattes and Cecil Frank Powell, the latter winning the Nobel Prize in Physics for this work. At the time of this discovery, they were all working at the H. H. Wills Laboratory of the University of Bristol. The X-ray satellite SAX was named BeppoSAX in his honour after its launch in 1996. Biography His father was the physicist Raffaele Augusto Occhialini (1878–1951), a pioneer in the fields of spectroscopy and electronics theory. Giuseppe Paolo Stanislao Occhialini graduated at Florence in 1929. In 1932, he collaborated in the discovery of the positron in cosmic rays at the Cavendish Laboratory of Cambridge, under the leadership of Patrick Blackett, using cloud chambers.
