Richard Zsigmondy
Richard Adolf Zsigmondy ( hu, Zsigmondy Richárd Adolf; 1 April 1865 – 23 September 1929) was an Austrian-born chemist. He was known for his research in colloids, for which he was awarded the Nobel Prize in chemistry in 1925, as well as for co-inventing the slit-ultramicroscope, and different membrane filters. The crater Zsigmondy on the Moon is named in his honour. Biography Early years Zsigmondy was born in Vienna, Austrian Empire, to a Hungarian gentry family. His mother Irma Szakmáry, a poet born in Martonvásár, and his father, Adolf Zsigmondy Sr., a scientist from Pressburg (Pozsony, today's Bratislava) who invented several surgical instruments for use in dentistry. Zsigmondy family members were Lutherans. They originated from Johannes ( hu, János) Sigmondi (1686–1746, Bártfa, Kingdom of Hungary) and included teachers, priests and Hungarian freedom-fighters.

Ultramicroscope
An ultramicroscope is a microscope with a system that lights the object in a way that allows viewing of tiny particles via light scattering, and not light reflection or absorption. When the diameter of a particle is below or near the wavelength of visible light (around 500 nanometers), the particle cannot be seen in a light microscope with the usual methods of illumination. The ''ultra-'' in ''ultramicroscope'' refers to the ability to see objects whose diameter is shorter than the wavelength of visible light, on the model of the ''ultra-'' in ''ultraviolet''. Synopsis In the system, the particles to be observed are dispersed in a liquid or gas colloid (or less often in a coarser suspension). The colloid is placed in a light-absorbing, dark enclosure, and illuminated with a convergent beam of intense light entering from one side. Light hitting the colloid particles will be scattered. In discussions about light scattering, the converging beam is called a "Tyndall cone". The scene is ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Emil Zsigmondy
Emil Zsigmondy (11 August 1861 – 6 August 1885) was an Austrian physician and mountaineer. Life Zsigmondy's parents were Hungarians: Adolf Zsigmondy, born in Pozsony, and Irma von Szakmáry, born in Martonvásár. Zsigmondy was an excellent alpinist, known for the risky nature of many of his climbs. He began mountaineering as a teenager, climbing the Reisseck in Austria in a round trip of 26 hours with his brother, Otto Zsigmondy. By the late 1870s the two brothers were climbing without guides in the Zillertal Alps. In 1881, they climbed the Ortler from the Hochjoch. Emil Zsigmondy was the friend and companion of Ludwig Purtscheller, the great pioneer of guideless Alpine climbing. Emil and Otto climbed with Purtscheller in 1882 and 1884, including an ascent without guides of the Marinelli Couloir on Monte Rosa and the first guideless traverse of the Matterhorn.''Mountaineers'' (Douglas/Smithsonian), p. 115. Zsigmondy's outstanding achievements include the first ascen ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Otto Zsigmondy
Otto is a masculine German given name and a surname. It originates as an Old High German short form (variants ''Audo'', ''Odo'', ''Udo'') of Germanic names beginning in ''aud-'', an element meaning "wealth, prosperity". The name is recorded from the 7th century ( Odo, son of Uro, courtier of Sigebert III). It was the name of three 10th-century German kings, the first of whom was Otto I the Great, the first Holy Roman Emperor, founder of the Ottonian dynasty. The Gothic form of the prefix was ''auda-'' (as in e.g. '' Audaþius''), the Anglo-Saxon form was ''ead-'' (as in e.g. ''Eadmund''), and the Old Norse form was '' auð-''. The given name Otis arose from an English surname, which was in turn derived from ''Ode'', a variant form of ''Odo, Otto''. Due to Otto von Bismarck, the given name ''Otto'' was strongly associated with the German Empire in the later 19th century. It was comparatively frequently given in the United States (presumably in German American families) during t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mountaineering
Mountaineering or alpinism, is a set of outdoor activities that involves ascending tall mountains. Mountaineering-related activities include traditional outdoor climbing, skiing, and traversing via ferratas. Indoor climbing, sport climbing, and bouldering are also considered variants of mountaineering by some. Unlike most sports, mountaineering lacks widely applied formal rules, regulations, and governance; mountaineers adhere to a large variety of techniques and philosophies when climbing mountains. Numerous local alpine clubs support mountaineers by hosting resources and social activities. A federation of alpine clubs, the International Climbing and Mountaineering Federation (UIAA), is the International Olympic Committee-recognized world organization for mountaineering and climbing. The consequences of mountaineering on the natural environment can be seen in terms of individual components of the environment (land relief, soil, vegetation, fauna, and landscape) and location/z ...

Climbing
Climbing is the activity of using one's hands, feet, or any other part of the body to ascend a steep topographical object that can range from the world's tallest mountains (e.g. the eight thousanders), to small boulders. Climbing is done for locomotion, sporting recreation, and for competition, and is also done in trades that rely on ascension; such as emergency rescue and military operations. Climbing is done indoors and outdoors and on natural (e.g. rock and ice) and artificial surfaces. Professional mountain guides or rock climbing guides (e.g. the UIAGM), were a significant element in developing the popularity of the sport in the natural environment, and remain so today. Since the 1980s, the development of competition climbing and the availability of artificial climbing walls have dramatically increased the popularity of rock climbing as a sport and led to the emergence of professional rock climbers, such as Wolfgang Güllich, Chris Sharma, Lynn Hill and Catherine ...

Kingdom Of Hungary
The Kingdom of Hungary was a monarchy in Central Europe that existed for nearly a millennium, from the Middle Ages into the 20th century. The Principality of Hungary emerged as a Christian kingdom upon the coronation of the first king Stephen I at Esztergom around the year 1000;Kristó Gyula – Barta János – Gergely Jenő: Magyarország története előidőktől 2000-ig (History of Hungary from the prehistory to 2000), Pannonica Kiadó, Budapest, 2002, , p. 687, pp. 37, pp. 113 ("Magyarország a 12. század második felére jelentős európai tényezővé, középhatalommá vált."/"By the 12th century Hungary became an important European factor, became a middle power.", "A Nyugat részévé vált Magyarország.../Hungary became part of the West"), pp. 616–644 his family (the Árpád dynasty) led the monarchy for 300 years.

Bártfa
Bardejov (; hu, Bártfa, german: Bartfeld, rue, Бардеёв, uk, Бардіїв) is a town in North-Eastern Slovakia. It is situated in the Šariš region on a floodplain terrace of the Topľa River, in the hills of the Beskyd Mountains. It exhibits numerous cultural monuments in its completely intact medieval town center. The town is one of UNESCO's World Heritage Sites and currently maintains a population of about 32,000 inhabitants. Etymology There are two theories about the origin of the name. According to one theory, the name town comes from the Hungarian word ''"bárd"'' ( en, 'chopper, hatchet'), which indicated an amount of forested territory which could be chopped down by one man in one day. In the Hungarian name (Bártfa), the ''"fa"'' (English: "tree") suffix came later, and it also changed the last letter of "''bárd''" to "''bárt''", for easier pronunciation. Another theory derives the name from a Christian personal name ''Barděj'', ''Barduj'' (abbreviated ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Adolf Zsigmondy
Dr. Adolf Zsigmondy, aka Adolph Zsigmondy (24 April 1816 in Pozsony (german: Pressburg), Kingdom of Hungary – 23 June 1880 in Vienna, Austria-Hungary) was a dentist of Hungarian origin who lived in Vienna. He is best known for inventing the idea of charting teeth on the Zsigmondy-cross (named after him). This is the basis of the presently used marking method recommended by the FDI. He was also the first to describe the contact and wear of the approximal side of the teeth. He continued to develop the cohesive gold fillings. His eldest son, Ottó Zsigmondy, was also a dentist. His more limited professional field of research was the preserving dentistry. He used sodium-superoxide for widening the root canal and he made permanent fillings of black hard gutta percha. On the basis of observations carried out on himself he described the two-phase or temporal mastication called after him. He was also much engaged with professional politics, in his publications he strove for recogni ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
