Jozef Stefan
Josef Stefan (; 24 March 1835 – 7 January 1893) was a Carinthian Slovene physicist, mathematician, and poet of the Austrian Empire. Life and work Stefan was born in the village of St. Peter (Slovene: ) on the outskirts of Klagenfurt) to Aleš (Aleksander) Stefan (1805-1872) and Marija Startinik (1815-1863). His parents, both ethnic Slovenes, did not marry until Josef was eleven. The Stefans were of modest means; his father was a milling assistant and his mother served as a maidservant. Josef was their only child. Stefan attended elementary school in Klagenfurt, where he showed talent, and was recommended for enrollment at the in 1845. At thirteen, he experienced the revolutionary year of 1848, which inspired him to show sympathy toward the Slovene literary and national movement. After having graduated top of his class in high school, he briefly considered joining the Benedictine Order, but his great interest in physics prevailed. He left for Vienna in 1853 to study mat ...

Maxwell–Stefan Diffusion
The Maxwell–Stefan diffusion (or Stefan–Maxwell diffusion) is a model for describing diffusion in multicomponent systems. The equations that describe these transport processes have been developed independently and in parallel by James Clerk MaxwellJ. C. Maxwell: ''On the dynamical theory of gases'', The Scientific Papers of J. C. Maxwell, 1965, 2, 26–78. for dilute gases and Josef StefanJ. Stefan: ''Über das Gleichgewicht und Bewegung, insbesondere die Diffusion von Gemischen'', Sitzungsberichte der Kaiserlichen Akademie der Wissenschaften Wien, 2te Abteilung a, 1871, 63, 63–124. for liquids.

Austrian Academy Of Sciences
The Austrian Academy of Sciences (; ÖAW) is a legal entity under the special protection of the Republic of Austria. According to the statutes of the Academy its mission is to promote the sciences and humanities in every respect and in every field, particularly in fundamental research. History In 1713, Gottfried Wilhelm Leibniz suggested to establish an Academy, inspired by the Royal Society and the French Academy of Sciences. The "Kaiserliche Akademie der Wissenschaften in Wien" was finally established by Imperial Patent on 14 May 1847. The academy soon began extensive research. In the humanities the academy started with researching and publishing important historical sources of Austria. Research in natural science also covered a wide variety of topics. The 1921 federal law guaranteed the legal basis of the academy in the newly founded First Austrian Republic. From the mid-1960s onwards it became the country's leading institution in the field of non-university basic research. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mathematical Physics
Mathematical physics is the development of mathematics, mathematical methods for application to problems in physics. The ''Journal of Mathematical Physics'' defines the field as "the application of mathematics to problems in physics and the development of mathematical methods suitable for such applications and for the formulation of physical theories". An alternative definition would also include those mathematics that are inspired by physics, known as physical mathematics. Scope There are several distinct branches of mathematical physics, and these roughly correspond to particular historical parts of our world. Classical mechanics Applying the techniques of mathematical physics to classical mechanics typically involves the rigorous, abstract, and advanced reformulation of Newtonian mechanics in terms of Lagrangian mechanics and Hamiltonian mechanics (including both approaches in the presence of constraints). Both formulations are embodied in analytical mechanics and lead ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Habilitation
Habilitation is the highest university degree, or the procedure by which it is achieved, in Germany, France, Italy, Poland and some other European and non-English-speaking countries. The candidate fulfills a university's set criteria of excellence in research, teaching, and further education, which usually includes a dissertation. The degree, sometimes abbreviated ''Dr. habil''. (), ''dr hab.'' (), or ''D.Sc.'' ('' Doctor of Sciences'' in Russia and some CIS countries), is often a qualification for full professorship in those countries. In German-speaking countries it allows the degree holder to bear the title ''PD'' (for ). In a number of countries there exists an academic post of docent, appointment to which often requires such a qualification. The degree conferral is usually accompanied by a public oral defence event (a lecture or a colloquium) with one or more opponents. Habilitation is usually awarded 5–15 years after a PhD degree or its equivalent. Achieving this ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Physics
Physics is the scientific study of matter, its Elementary particle, fundamental constituents, its motion and behavior through space and time, and the related entities of energy and force. "Physical science is that department of knowledge which relates to the order of nature, or, in other words, to the regular succession of events." It is one of the most fundamental scientific disciplines. "Physics is one of the most fundamental of the sciences. Scientists of all disciplines use the ideas of physics, including chemists who study the structure of molecules, paleontologists who try to reconstruct how dinosaurs walked, and climatologists who study how human activities affect the atmosphere and oceans. Physics is also the foundation of all engineering and technology. No engineer could design a flat-screen TV, an interplanetary spacecraft, or even a better mousetrap without first understanding the basic laws of physics. (...)

Mathematics
Mathematics is a field of study that discovers and organizes methods, Mathematical theory, theories and theorems that are developed and Mathematical proof, proved for the needs of empirical sciences and mathematics itself. There are many areas of mathematics, which include number theory (the study of numbers), algebra (the study of formulas and related structures), geometry (the study of shapes and spaces that contain them), Mathematical analysis, analysis (the study of continuous changes), and set theory (presently used as a foundation for all mathematics). Mathematics involves the description and manipulation of mathematical object, abstract objects that consist of either abstraction (mathematics), abstractions from nature orin modern mathematicspurely abstract entities that are stipulated to have certain properties, called axioms. Mathematics uses pure reason to proof (mathematics), prove properties of objects, a ''proof'' consisting of a succession of applications of in ...

Order Of Saint Benedict
The Benedictines, officially the Order of Saint Benedict (, abbreviated as O.S.B. or OSB), are a mainly contemplative monastic order of the Catholic Church for men and for women who follow the Rule of Saint Benedict. Initiated in 529, they are the oldest of all the religious orders in the Latin Church. The male religious are also sometimes called the Black Monks, especially in English speaking countries, after the colour of their habits, although some, like the Olivetans, wear white. They were founded by Benedict of Nursia, a 6th-century Italian monk who laid the foundations of Benedictine monasticism through the formulation of his Rule. Benedict's sister, Scholastica, possibly his twin, also became a religious from an early age, but chose to live as a hermit. They retained a close relationship until her death. Despite being called an order, the Benedictines do not operate under a single hierarchy. They are instead organized as a collection of autonomous monasteries a ...

Slovene Literature
Slovene literature is the literature written in Slovene. It spans across all literary genres with historically the Slovene historical fiction as the most widespread Slovene fiction genre. The Romantic 19th-century epic poetry written by the leading name of the Slovene literary canon, France Prešeren, inspired virtually all subsequent Slovene literature. Literature played an important role in the development and preservation of Slovene identity because the Slovene nation did not have its own state until 1991 after the Republic of Slovenia emerged from the breakup of Yugoslavia. Poetry, narrative prose, drama, essay, and criticism kept the Slovene language and culture alive, allowing—in the words of Anton Slodnjak—the Slovenes to become a real nation, particularly in the absence of "masculine" attributes such as political power and authority. Early literature There are accounts that cite the existence of an oral literary tradition that preceded the Slovene written l ...

Revolutions Of 1848
The revolutions of 1848, known in some countries as the springtime of the peoples or the springtime of nations, were a series of revolutions throughout Europe over the course of more than one year, from 1848 to 1849. It remains the most widespread revolutionary wave in European history to date. The revolutions were essentially Democracy, democratic and Liberalism, liberal in nature, with the aim of removing the old Monarchy, monarchical structures and creating independent nation-states, as envisioned by romantic nationalism. The revolutions spread across Europe after an initial revolution began in Sicilian revolution of 1848, Italy in January 1848. Over 50 countries were affected, but with no significant coordination or cooperation among their respective revolutionaries. Some of the major contributing factors were widespread dissatisfaction with political leadership, demands for more participation (decision making), participation in government and democracy, demands for freedom o ...

Physicist
A physicist is a scientist who specializes in the field of physics, which encompasses the interactions of matter and energy at all length and time scales in the physical universe. Physicists generally are interested in the root or ultimate causes of Phenomenon, phenomena, and usually frame their understanding in mathematical terms. They work across a wide range of Physics#Research fields, research fields, spanning all length scales: from atom, sub-atomic and particle physics, through biological physics, to physical cosmology, cosmological length scales encompassing the universe as a whole. The field generally includes two types of physicists: Experimental physics, experimental physicists who specialize in the observation of natural phenomena and the development and analysis of experiments, and Theoretical physics, theoretical physicists who specialize in mathematical modeling of physical systems to rationalize, explain and predict natural phenomena. Physicists can apply their k ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
