Elementary Particle
In particle physics, an elementary particle or fundamental particle is a subatomic particle that is not composed of other particles. The Standard Model presently recognizes seventeen distinct particles—twelve fermions and five bosons. As a consequence of flavor and color combinations and antimatter, the fermions and bosons are known to have 48 and 13 variations, respectively. Among the 61 elementary particles embraced by the Standard Model number: electrons and other leptons, quarks, and the fundamental bosons. Subatomic particles such as protons or neutrons, which contain two or more elementary particles, are known as composite particles. Ordinary matter is composed of atoms, themselves once thought to be indivisible elementary particles. The name ''atom'' comes from the Ancient Greek word ''ἄτομος'' ( atomos) which means ''indivisible'' or ''uncuttable''. Despite the theories about atoms that had existed for thousands of years, the factual existence of ato ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Miramare Castle
Miramare Castle (; ; ; ) is a 19th-century castle direct on the Gulf of Trieste between Barcola and Grignano (Trieste), Grignano in Trieste, northeastern Italy. It was built from 1856 to 1860 for Austrian Empire, Austrian Archduke Ferdinand Maximilian and his wife, Charlotte of Belgium, later Emperor Maximilian I of Mexico and Empress Charlotte of Belgium, Carlota of Second Mexican Empire, Mexico, based on a design by Carl Junker. The castle's grounds include an extensive cliff and seashore park of designed by the archduke. The grounds were completely re-landscaped to feature numerous tropical species of trees and plants. History Miramare Castle Miramare Castle and its park were built by order of Ferdinand Maximilian (1832–1867), of the House of Habsburg-Lorraine. In 1850, at the age of eighteen, Ferdinand Maximilian - younger brother of Franz Joseph I of Austria, Franz Joseph, Emperor of Austria - came to Trieste with his own younger brother, Archduke Charles Louis of Aus ...

1926 Births
In Turkey, the year technically contained only 352 days. As Friday, December 18, 1926 ''(Julian Calendar)'' was followed by Saturday, January 1, 1927 '' (Gregorian Calendar)''. 13 days were dropped to make the switch. Turkey thus became the last country to officially adopt the Gregorian Calendar, which ended the 344-year calendrical switch around the world that took place in October, 1582 by virtue of the Papal Bull made by Pope Gregory XIII.

Marian Smoluchowski Medal
The Marian Smoluchowski Medal is a Polish annual science award conferred by the Polish Physical Society (''Polskie Towarzystwo Fizyczne, PTF'') for contributions in the field of physics. Description The medal was established in 1965 and is the highest award presented by the Polish Physical Society. It was named in honour of physicist Marian Smoluchowski (1872 – 1917). It is awarded to scientists whose work significantly contributed to the advancement of one of the branches of physics irrespective of the scientific degree, place of work or nationality of the laureate. It can be given for a single published work or as a lifetime achievement award. It is conferred by the Awards Committee of the Polish Physical Society, currently, no more than once a year. Three laureates of the medal have also received the Nobel Prize in Physics: Ben Roy Mottelson (1975), Subrahmanyan Chandrasekhar (1983) and Vitaly Ginzburg (2003).

Analytical Mechanics
In theoretical physics and mathematical physics, analytical mechanics, or theoretical mechanics is a collection of closely related formulations of classical mechanics. Analytical mechanics uses '' scalar'' properties of motion representing the system as a whole—usually its kinetic energy and potential energy. The equations of motion are derived from the scalar quantity by some underlying principle about the scalar's variation. Analytical mechanics was developed by many scientists and mathematicians during the 18th century and onward, after Newtonian mechanics. Newtonian mechanics considers vector quantities of motion, particularly accelerations, momenta, forces, of the constituents of the system; it can also be called ''vectorial mechanics''. A scalar is a quantity, whereas a vector is represented by quantity and direction. The results of these two different approaches are equivalent, but the analytical mechanics approach has many advantages for complex problems. Analytica ...

Leptons
In particle physics, a lepton is an elementary particle of half-integer spin ( spin ) that does not undergo strong interactions. Two main classes of leptons exist: charged leptons (also known as the electron-like leptons or muons), including the electron, muon, and tauon, and neutral leptons, better known as neutrinos. Charged leptons can combine with other particles to form various composite particles such as atoms and positronium, while neutrinos rarely interact with anything, and are consequently rarely observed. The best known of all leptons is the electron. There are six types of leptons, known as '' flavours'', grouped in three '' generations''. The first-generation leptons, also called ''electronic leptons'', comprise the electron () and the electron neutrino (); the second are the ''muonic leptons'', comprising the muon () and the muon neutrino (); and the third are the ''tauonic leptons'', comprising the tau () and the tau neutrino (). Electrons have the least m ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Quark
A quark () is a type of elementary particle and a fundamental constituent of matter. Quarks combine to form composite particles called hadrons, the most stable of which are protons and neutrons, the components of atomic nucleus, atomic nuclei. All commonly observable matter is composed of up quarks, down quarks and electrons. Owing to a phenomenon known as ''color confinement'', quarks are never found in isolation; they can be found only within hadrons, which include baryons (such as protons and neutrons) and mesons, or in quark–gluon plasmas. There is also the theoretical possibility of #Other_phases_of_quark_matter, more exotic phases of quark matter. For this reason, much of what is known about quarks has been drawn from observations of hadrons. Quarks have various Intrinsic and extrinsic properties, intrinsic physical property, properties, including electric charge, mass, color charge, and Spin (physics), spin. They are the only elementary particles in the Standard Mode ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Relativistic Quantum Mechanics
In physics, relativistic quantum mechanics (RQM) is any Poincaré- covariant formulation of quantum mechanics (QM). This theory is applicable to massive particles propagating at all velocities up to those comparable to the speed of light ''c'', and can accommodate massless particles. The theory has application in high-energy physics, particle physics and accelerator physics, as well as atomic physics, chemistry and condensed matter physics. ''Non-relativistic quantum mechanics'' refers to the mathematical formulation of quantum mechanics applied in the context of Galilean relativity, more specifically quantizing the equations of classical mechanics by replacing dynamical variables by operators. ''Relativistic quantum mechanics'' (RQM) is quantum mechanics applied with special relativity. Although the earlier formulations, like the Schrödinger picture and Heisenberg picture were originally formulated in a non-relativistic background, a few of them (e.g. the Dirac or path-i ...

Jan Rzewuski
Jan Rzewuski (December 19, 1916, in Łódź – September 17, 1994, in Wrocław) was a Polish theoretical physicist, a member of Polish resistance during World War II and a participant in the Warsaw Uprising. Rzewuski finished a gimnazjum in Łódź in 1934 and between 1934 and 1939 studied chemistry in Lwów and Gdańsk. From the start of the German occupation of Poland until 1942 he worked in the cotton industry in Łódź as an ordinary worker. In the next two years he studied theoretical physics in a secret underground (Poles were forbidden to study past the elementary level during the German occupation) university organized by the University of Warsaw. As part of the Polish Home Army (AK) he fought in the Warsaw Uprising for which he was later decorated with the Cross of Valor and the Cross of the Uprising. After the war, in 1945, he worked a lecturer at the Lublin Polytechnic. In 1946 he moved back to Warsaw, where he took a position at the University of Warsaw and whe ...
