Viktor Von Lang
Viktor von Lang (2 March 1838 – 3 July 1921) was an Austrian chemist. He is counted among the pioneers and founders of crystal physics. Career Lang earned his doctorate from the University of Giessen in 1859 with a thesis titled "Physikalische Verhältnisse kristallisierter Körper". From 1865 to 1909, Lang served as director of the ''Physikalisches Kabinett'' in Vienna. His book on introductory theoretical physics, ''Einleitung in die theoretische physik'', was published in eight editions from 1867 to 1891. With crystallographer Wilhelm Josef Grailich, he was co-author of ''Untersuchungen über die Physikalischen Verhältnisse Krystallisirter Körper'' ("Investigations into the physical conditions of crystallized bodies"). The mineral langite was named in his honor by Nevil Story Maskelyne Mervyn Herbert Nevil Story Maskelyne (3 September 1823 – 20 May 1911) was an English geologist and politician.

Nevil Story Maskelyne
Mervyn Herbert Nevil Story Maskelyne (3 September 1823 – 20 May 1911) was an English geologist and politician. Scientific career Educated at Wadham College, Oxford, Maskelyne taught mineralogy and chemistry at Oxford from 1851, before becoming a professor of mineralogy, 1856–95. He was Keeper of Minerals at the British Museum from 1857 to 1880. He was made an honorary Fellow of Wadham in 1873. Maskelyne was also a pioneer of photography and an associate of Fox Talbot. The meteoritic mineral ''maskelynite'' was named after him. Family Mervyn was the eldest son of Antony Mervin Reeve Story and Margaret Maskelyne, the daughter of the Astronomer Royal, Nevil Maskelyne. The family adopted the name of Maskelyne on Nevil's coming of age as they had inherited that family's estate at Basset Down in Wiltshire. Mervyn married Thereza Mary Dillwyn-Llewelyn (1834 – 21 February 1926) - Welsh astronomer and pioneer in scientific photography - on 29 June 1858. Their daughter Mar ...

Langite
Langite is a rare hydrated copper sulfate mineral, with hydroxyl, found almost exclusively in druses of small crystals. It is formed from the oxidation of copper sulfides, and was first described in specimens from Cornwall, United Kingdom. It is dimorphous with wroewolfeite. Langite was discovered in 1864 and named after the physicist and crystallographer Viktor von Lang (1838–1921), who was Professor of Physics at the University of Vienna, Austria. Unit cell Langite belongs to the monoclinic crystal class m, meaning that it has just one mirror plane, and no axes of rotational symmetry. The crystal is built up of identical unit cells stacked together, with no space in between. The unit cell for the monoclinic system has a base which is a rhombus, with sides a and c inclined at angle β. The third side b is perpendicular to both a and c. For langite the angle β is very close to 90°, so the unit cell is almost brick-shaped (as for the orthorhombic system). Differe ...

Wilhelm Josef Grailich
Wilhelm Joseph Grailich (16 February 1829, in Pressburg – 13 September 1859, in Vienna) was an Austrian physicist, mineralogist and crystallographer. Education From 1847, Grailich studied sciences at the polytechnic institute in Vienna. Career Grailich served as an assistant to Andreas von Ettingshausen in the institute of physics at the University of Vienna. In 1856 he became an assistant at the ''Hofmineraliencabinett'', where soon afterwards, he succeeded Gustav Adolf Kenngott as " kustos-adjunkt". In 1857 he became an associate professor of higher physics at the university, and in 1859, was chosen as a member of the Vienna Academy of Sciences.

Crystallography
Crystallography is the experimental science of determining the arrangement of atoms in crystalline solids. Crystallography is a fundamental subject in the fields of materials science and solid-state physics (condensed matter physics). The word "crystallography" is derived from the Greek word κρύσταλλος (''krystallos'') "clear ice, rock-crystal", with its meaning extending to all solids with some degree of transparency, and γράφειν (''graphein'') "to write". In July 2012, the United Nations recognised the importance of the science of crystallography by proclaiming that 2014 would be the International Year of Crystallography. denote a direction vector (in real space). * Coordinates in ''angle brackets'' or ''chevrons'' such as <100> denote a ''family'' of directions which are related by symmetry operations.

Theoretical Physics
Theoretical physics is a branch of physics that employs mathematical models and abstractions of physical objects and systems to rationalize, explain and predict natural phenomena. This is in contrast to experimental physics, which uses experimental tools to probe these phenomena. The advancement of science generally depends on the interplay between experimental studies and theory. In some cases, theoretical physics adheres to standards of mathematical rigour while giving little weight to experiments and observations.There is some debate as to whether or not theoretical physics uses mathematics to build intuition and illustrativeness to extract physical insight (especially when normal experience fails), rather than as a tool in formalizing theories. This links to the question of it using mathematics in a less formally rigorous, and more intuitive or heuristic way than, say, mathematical physics. For example, while developing special relativity, Albert Einstein was concerned wit ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Crystal Physics
Solid-state physics is the study of rigid matter, or solids, through methods such as quantum mechanics, crystallography, electromagnetism, and metallurgy. It is the largest branch of condensed matter physics. Solid-state physics studies how the large-scale properties of solid materials result from their atomic-scale properties. Thus, solid-state physics forms a theoretical basis of materials science. It also has direct applications, for example in the technology of transistors and semiconductors. Background Solid materials are formed from densely packed atoms, which interact intensely. These interactions produce the mechanical (e.g. hardness and elasticity), thermal, electrical, magnetic and optical properties of solids. Depending on the material involved and the conditions in which it was formed, the atoms may be arranged in a regular, geometric pattern (crystalline solids, which include metals and ordinary water ice) or irregularly (an amorphous solid such as common wi ...

Austrian Empire
The Austrian Empire (german: link=no, Kaiserthum Oesterreich, modern spelling , ) was a Central-Eastern European multinational great power from 1804 to 1867, created by proclamation out of the realms of the Habsburgs. During its existence, it was the third most populous monarchy in Europe after the Russian Empire and the United Kingdom. Along with Prussia, it was one of the two major powers of the German Confederation. Geographically, it was the third-largest empire in Europe after the Russian Empire and the First French Empire (). The empire was proclaimed by Francis II, Holy Roman Emperor, Francis II in 1804 in response to Napoleon's declaration of the First French Empire, unifying all Habsburg monarchy, Habsburg possessions under one central government. It remained part of the Holy Roman Empire until the latter's dissolution in 1806. It continued fighting against Napoleon throughout the Napoleonic Wars, except for a period between 1809 and 1813, when Austria was first all ...

Chemist
A chemist (from Greek ''chēm(ía)'' alchemy; replacing ''chymist'' from Medieval Latin ''alchemist'') is a scientist trained in the study of chemistry. Chemists study the composition of matter and its properties. Chemists carefully describe the properties they study in terms of quantities, with detail on the level of molecules and their component atoms. Chemists carefully measure substance proportions, chemical reaction rates, and other chemical properties. In Commonwealth English, pharmacists are often called chemists. Chemists use their knowledge to learn the composition and properties of unfamiliar substances, as well as to reproduce and synthesize large quantities of useful naturally occurring substances and create new artificial substances and useful processes. Chemists may specialize in any number of subdisciplines of chemistry. Materials scientists and metallurgists share much of the same education and skills with chemists. The work of chemists is often related to the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
