Oton Kučera
Oton Kučera (1 January 1857, Petrinja – 29 December 1931, Zagreb) was a Croatian astronomer. He played a crucial role by popularizing science and technology in Croatia. He was also the president of Matica hrvatska and the author of several physics handbooks for primary school and a series of popular scientific works from the areas of physics, astronomy and electrical engineering. Youth He was born in Petrinja as the first of thirteen children of Ida Bošnjaković and Franjo Kučera, a teacher. His son Vlaho later claimed that Oton was born on December 31, 1856, but that pragmatic reasons (such as the army service) prompted his parents to move the date by one day. Oton celebrated his birthday on January 1, as shown by the celebration of his 70th birthday in 1927. Through his paternal grandfather Václav Kučera, who moved from Staré Hamry to Glina, Oton was of Czech descent. Oton's father was soon transferred, so the family left Petrinja and settled in Otočac, where Oton ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Military Frontier
The Military Frontier (german: Militärgrenze, sh-Latn, Vojna krajina/Vojna granica, Војна крајина/Војна граница; hu, Katonai határőrvidék; ro, Graniță militară) was a borderland of the Habsburg monarchy and later the Austrian and Austro-Hungarian Empire. It acted as the ''cordon sanitaire'' against incursions from the Ottoman Empire. The establishment of the new defense system in Hungary and Croatia took place in the 16th century, following the election of Ferdinand I as king. Six districts under special military administration were established in Hungary and Croatia. The Croatian Military Frontier and the Slavonian Military Frontier came under the jurisdiction of the Croatian Sabor and ban. In 1627, they were placed under the direct control of the Habsburg military. For more than two centuries, they would retain complete civilian and military authority over the area, up to the abolition of the Military Frontier in 1881. During the 17th ce ...

Observatory
An observatory is a location used for observing terrestrial, marine, or celestial events. Astronomy, climatology/meteorology, geophysical, oceanography and volcanology are examples of disciplines for which observatories have been constructed. Historically, observatories were as simple as containing an astronomical sextant (for measuring the distance between stars) or Stonehenge (which has some alignments on astronomical phenomena). Astronomical observatories Astronomical observatories are mainly divided into four categories: space-based, airborne, ground-based, and underground-based. Ground-based observatories Ground-based observatories, located on the surface of Earth, are used to make observations in the radio and visible light portions of the electromagnetic spectrum. Most optical telescopes are housed within a dome or similar structure, to protect the delicate instruments from the elements. Telescope domes have a slit or other opening in the roof that can be opened during ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Požega, Croatia
Požega () is a city in western Slavonia, eastern Croatia, with a total population of 22,364 (census 2021). It is the administrative center of the Požega-Slavonia County. Name Between 1921 and 1991, the town was known as ''Slavonska Požega''. In German language, German, the town is known as ''Poschegg'', in Hungarian language, Hungarian as ''Pozsega'', in Turkish language, Turkish as ''Pojega'', and in Latin language, Latin as ''Incerum'' (-i, n.) and ''Possega''. There is a town in Serbia with same name (see: Požega, Serbia). "Požega" is supposed to be related to the Croatian word "požar", meaning "forest fire". "Incerum" is supposed to come from Proto-Indo-European words *h1eyn (valley) and *kjer (heart), so that it means "the heart of the valley". Geography Požega (elevation: ) is located in the south-western part of the Valley of Požega, or Požega basin, in Croatian: ''Požeška kotlina''. This fertile valley has been important since the antiquity - its Ancient Rome, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Natural Sciences
Natural science is one of the branches of science concerned with the description, understanding and prediction of natural phenomena, based on empirical evidence from observation and experimentation. Mechanisms such as peer review and repeatability of findings are used to try to ensure the validity of scientific advances. Natural science can be divided into two main branches: life science and physical science. Life science is alternatively known as biology, and physical science is subdivided into branches: physics, chemistry, earth science, and astronomy. These branches of natural science may be further divided into more specialized branches (also known as fields). As empirical sciences, natural sciences use tools from the formal sciences, such as mathematics and logic, converting information about nature into measurements which can be explained as clear statements of the " laws of nature". Modern natural science succeeded more classical approaches to natural philosophy, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Gymnasium (school)
''Gymnasium'' (and variations of the word) is a term in various European languages for a secondary school that prepares students for higher education at a university. It is comparable to the US English term '' preparatory high school''. Before the 20th century, the gymnasium system was a widespread feature of educational systems throughout many European countries. The word (), from Greek () 'naked' or 'nude', was first used in Ancient Greece, in the sense of a place for both physical and intellectual education of young men. The latter meaning of a place of intellectual education persisted in many European languages (including Albanian, Bulgarian, Estonian, Greek, German, Hungarian, the Scandinavian languages, Dutch, Polish, Czech, Serbo-Croatian, Macedonian, Slovak, Slovenian and Russian), whereas in other languages, like English (''gymnasium'', ''gym'') and Spanish (''gimnasio''), the former meaning of a place for physical education was retained.

Johann Josef Loschmidt
Johann Josef Loschmidt (15 March 1821 – 8 July 1895), who referred to himself mostly as Josef Loschmidt (omitting his first name), was a notable Austrian scientist who performed ground-breaking work in chemistry, physics (thermodynamics, optics, electrodynamics), and crystal forms. Born in Karlsbad, a town located in the Austrian Empire (now Karlovy Vary, Czech Republic), Loschmidt became professor of physical chemistry at the University of Vienna in 1868. He had two early mentors. The first was a Bohemian priest, Adalbert Czech, who persuaded Loschmidt's parents to send young Josef to high school in the Piarist monastery in Schlackenwerth and, in 1837, to advanced high-school classes in Prague. This was followed by two years of philosophy and mathematics at Prague's Charles University, where Loschmidt met his second important mentor. This was the philosophy professor Franz Serafin Exner, whose eyesight was failing, and who asked Loschmidt to be his personal reader. Exner wa ...

Ludwig Boltzmann
Ludwig Eduard Boltzmann (; 20 February 1844 – 5 September 1906) was an Austrian physicist and philosopher. His greatest achievements were the development of statistical mechanics, and the statistical explanation of the second law of thermodynamics. In 1877 he provided the current definition of entropy, S = k_ \ln \Omega \!, where Ω is the number of microstates whose energy equals the system's energy, interpreted as a measure of statistical disorder of a system. Max Planck named the constant the Boltzmann constant. Statistical mechanics is one of the pillars of modern physics. It describes how macroscopic observations (such as temperature and pressure) are related to microscopic parameters that fluctuate around an average. It connects thermodynamic quantities (such as heat capacity) to microscopic behavior, whereas, in classical thermodynamics, the only available option would be to measure and tabulate such quantities for various materials.
