Giuseppe Occhialini
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. He returned in Italy in 1934, where he suffered from the political climate generated by fascism. Thus, fr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Positron
The positron or antielectron is the antiparticle or the antimatter counterpart of the electron. It has an electric charge of +1 '' e'', a spin of 1/2 (the same as the electron), and the same mass as an electron. When a positron collides with an electron, annihilation occurs. If this collision occurs at low energies, it results in the production of two or more photons. Positrons can be created by positron emission radioactive decay (through weak interactions), or by pair production from a sufficiently energetic photon which is interacting with an atom in a material. History Theory In 1928, Paul Dirac published a paper proposing that electrons can have both a positive and negative charge. This paper introduced the Dirac equation, a unification of quantum mechanics, special relativity, and the then-new concept of electron spin to explain the Zeeman effect. The paper did not explicitly predict a new particle but did allow for electrons having either positive or negative ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cambridge
Cambridge ( ) is a university city and the county town in Cambridgeshire, England. It is located on the River Cam approximately north of London. As of the 2021 United Kingdom census, the population of Cambridge was 145,700. Cambridge became an important trading centre during the Roman and Viking ages, and there is archaeological evidence of settlement in the area as early as the Bronze Age. The first town charters were granted in the 12th century, although modern city status was not officially conferred until 1951. The city is most famous as the home of the University of Cambridge, which was founded in 1209 and consistently ranks among the best universities in the world. The buildings of the university include King's College Chapel, Cavendish Laboratory, and the Cambridge University Library, one of the largest legal deposit libraries in the world. The city's skyline is dominated by several college buildings, along with the spire of the Our Lady and the English Martyrs ...

Asteroid
An asteroid is a minor planet of the inner Solar System. Sizes and shapes of asteroids vary significantly, ranging from 1-meter rocks to a dwarf planet almost 1000 km in diameter; they are rocky, metallic or icy bodies with no atmosphere. Of the roughly one million known asteroids the greatest number are located between the orbits of Mars and Jupiter, approximately 2 to 4 AU from the Sun, in the main asteroid belt. Asteroids are generally classified to be of three types: C-type, M-type, and S-type. These were named after and are generally identified with carbonaceous, metallic, and silicaceous compositions, respectively. The size of asteroids varies greatly; the largest, Ceres, is almost across and qualifies as a dwarf planet. The total mass of all the asteroids combined is only 3% that of Earth's Moon. The majority of main belt asteroids follow slightly elliptical, stable orbits, revolving in the same direction as the Earth and taking from three to six years to comple ...

The University of Milano-Bicocca ( it, Università degli Studi di Milano-Bicocca, UNIMIB) is a public university located in Milan, Italy, providing undergraduate, graduate and post-graduate education. Established in 1998, it was ranked by the ''Times Higher Education'' 2014 ranking of the best 100 Universities under 50 years old as number 21 worldwide and first in Italy. Campus The University of Milano-Bicocca is located in an area on the northern outskirts of Milan, which was occupied by the Pirelli industrial complex until the late 1980s. The industrial area has been redesigned by architect Vittorio Gregotti into an urban complex, including the University of Milano-Bicocca's research laboratories and student residence halls. History The University of Milano-Bicocca has its origins from the splitting of the University of Milan, which with about 90,000 students in the 1990s was becoming overcrowded. A large area in the north of Milan, the Bicocca, was chosen as the location f ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Kaon
KAON (Karlsruhe ontology) is an ontology infrastructure developed by the University of Karlsruhe and the Research Center for Information Technologies in Karlsruhe. Its first incarnation was developed in 2002 and supported an enhanced version of RDF ontologies. Several tools like the graphical ontology editor OIModeler or the KAON Server were based on KAON. There are ontology learning companion tools which take non-annotated natural language text as input: TextToOnto (KAON-based) and Text2Onto (KAON2-based). Text2Onto is based on the Probabilistic Ontology Model (POM). In 2005, the first version of KAON2 was released, offering fast reasoning support for OWL ontologies. KAON2 is not backward-compatible with KAON. KAON2 is developed as a joint effort of the Information Process Engineering (IPE) at the Research Center for Information Technologies (FZI), the Institute of Applied Informatics and Formal Description Methods (AIFB) at the University of Karlsruhe, and the Information Ma ...

Hugh Muirhead
Hugh Muirhead (1925 – 19 January 2007) was a British nuclear physicist and the last surviving author of the scientific paper announcing the discovery of the pion, a particle predicted by Hideki Yukawa. Muirhead did his PhD studies at the University of Bristol, where he, César Lattes and Giuseppe Occhialini, were part of Cecil Powell's group trying to confirm the existence of pions. Evidence was eventually found on 7 March 1947 by two of the group's technical team, Marietta Kurz and Irene Roberts. A paper was submitted to the journal ''Nature'' and published the same year. In 1950, Powell was awarded the Nobel Prize for the discovery. After gaining his PhD, Muirhead moved to the University of Glasgow and then the University of Liverpool in 1957, where he spent the rest of his career. Under his direction at Liverpool, it was experimentally confirmed that parity was violated in muon capture. He became a world authority on antiproton physics. As well as dozens of scientific pap ...
