Marcos Moshinsky
Marcos Moshinsky Borodiansky (russian: Маркос Мошинский Бородянский; uk, Маркос Мошинскі; 1921–2009) was a Mexican physicist of Ukrainian-Jewish origin whose work in the field of elementary particles won him the Prince of Asturias Prize for Scientific and Technical Investigation in 1988 and the UNESCO Science Prize in 1997. Early life He was born in 1921 into a Jewish family in Kyiv, Ukrainian SSR. At the age of three, he emigrated as a refugee to Mexico, where he became a naturalized citizen in 1942. He received a bachelor's degree in physics from the National Autonomous University of Mexico (UNAM) and a doctorate in the same discipline at Princeton University under Nobel Laureate Eugene Paul Wigner. Career In the 1950s he researched nuclear reactions and the structure of the atomic nucleus, introducing the concept of the '' transformation bracket for eigenstates of the quantum harmonic oscillator'', which, together with the tables ...

Bulletin Of The Atomic Scientists
The ''Bulletin of the Atomic Scientists'' is a nonprofit organization concerning science and global security issues resulting from accelerating technological advances that have negative consequences for humanity. The ''Bulletin'' publishes content at both a free-access website and a bi-monthly, nontechnical academic journal. The organization has been publishing continuously since 1945, when it was founded by former Manhattan Project scientists as the ''Bulletin of the Atomic Scientists of Chicago'' immediately following the atomic bombings of Hiroshima and Nagasaki. The organization is also the keeper of the symbolic Doomsday Clock, the time of which is announced each January. Background One of the driving forces behind the creation of the ''Bulletin'' was the amount of public interest surrounding atomic energy and rapid technological change at the dawn of the Atomic Age. In 1945 the public interest in Nuclear warfare, atomic warfare and Nuclear weaponry, weaponry inspired cont ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Colegio Nacional (Mexico)
The National College ( es, Colegio Nacional, links=no) is a Mexican honorary academy with a strictly limited membership created by presidential decree in 1943 in order to bring together the country's foremost artists and scientists, who are periodically invited to deliver lectures and seminars in their respective area of speciality. Membership is generally a lifelong commitment, although it could be forfeited under certain conditions. It should not be confused with ''El Colegio de México'', a public institution of higher education and research. History The college was founded on 8 April 1943. with the purpose of promoting Mexican culture and scholarship in a number of different fields. Its motto is "Libertad por saber" (Freedom through knowing) and its emblem is an eagle taking off (symbolizing freedom of thought) above a flaming sun (representing wisdom). The college's foundation decree, signed by General Manuel Ávila Camacho, limited membership to twenty Mexican-born citizens ...

Paris
Paris () is the capital and most populous city of France, with an estimated population of 2,165,423 residents in 2019 in an area of more than 105 km² (41 sq mi), making it the 30th most densely populated city in the world in 2020. Since the 17th century, Paris has been one of the world's major centres of finance, diplomacy, commerce, fashion, gastronomy, and science. For its leading role in the arts and sciences, as well as its very early system of street lighting, in the 19th century it became known as "the City of Light". Like London, prior to the Second World War, it was also sometimes called the capital of the world. The City of Paris is the centre of the Île-de-France region, or Paris Region, with an estimated population of 12,262,544 in 2019, or about 19% of the population of France, making the region France's primate city. The Paris Region had a GDP of €739 billion ($743 billion) in 2019, which is the highest in Europe. According to the Economist Intelli ...

Diffraction In Time
Diffraction in time is a phenomenon associated with the quantum dynamics of suddenly released matter waves initially confined in a region of space. It was introduced in 1952 by Marcos Moshinsky with the ''shutter problem''. A matter-wave beam stopped by an absorbing shutter exhibits an oscillatory density profile during its propagation after removal of the shutter. Whenever this propagation is accurately described by the time-dependent Schrödinger equation, the transient wave functions resemble the solutions that appear for the intensity of light subject to Fresnel diffraction by a straight edge. For this reason, the transient phenomenon was dubbed diffraction in time and has since then been recognised as ubiquitous in quantum dynamics. The experimental confirmation of this phenomenon was only achieved about half a century later in the group of ultracold atoms directed by Jean Dalibard Jean Dalibard (born 8 December 1958) is a French physicist, Professor at the École Polyt ...

Nuclear Shell Model
In nuclear physics, atomic physics, and nuclear chemistry, the nuclear shell model is a model of the atomic nucleus which uses the Pauli exclusion principle to describe the structure of the nucleus in terms of energy levels. The first shell model was proposed by Dmitri Ivanenko (together with E. Gapon) in 1932. The model was developed in 1949 following independent work by several physicists, most notably Eugene Paul Wigner, Maria Goeppert Mayer and J. Hans D. Jensen, who shared the 1963 Nobel Prize in Physics for their contributions. The nuclear shell model is partly analogous to the atomic shell model, which describes the arrangement of electrons in an atom in that filled shell results in better stability. When adding nucleons (protons or neutrons) to a nucleus, there are certain points where the binding energy of the next nucleon is significantly less than the last one. This observation that there are specific magic quantum numbers of nucleons (2, 8, 20, 28, 50, 82, 126) wh ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
