Heinz A. Lowenstam
Heinz Adolf Lowenstam (October 9, 1912 – June 7, 1993) was a German-born, Jewish-American paleoecologist celebrated for his discoveries in biomineralization: that living organisms manufacture substances such as the iron-containing mineral magnetite within their bodies. He is also renowned for his pioneering research on coral reefs and their influence on biologic processes in the geologic record. Early life and education Heinz Adolf Lowenstam was born in 1912 in Upper Silesia, which was then southeastern Germany but was ceded to Poland following World War I. His father, Kurt (1883–1965), was the younger brother of Rabbi Arthur Löwenstamm. His mother was Frieda Sternberg (b. 1889). He had a younger sister, Hildegard (Hilda), who married Kurt Weissenberg and had a daughter, Doris. Heinz's hometown of Siemjanowicz was located in a mining district, and his fascination with geology began as a child playing on the piles of mine tailings, against the backdrop of Germany's gr ...

Karl Von Frisch
Karl Ritter von Frisch, (20 November 1886 – 12 June 1982) was a German-Austrian ethologist who received the Nobel Prize in Physiology or Medicine in 1973, along with Nikolaas Tinbergen and Konrad Lorenz. His work centered on investigations of the sensory perceptions of the honey bee and he was one of the first to translate the meaning of the waggle dance. His theory, described in his 1927 book ''Aus dem Leben der Bienen'' (translated into English as ''The Dancing Bees''), was disputed by other scientists and greeted with skepticism at the time. Only much later was it shown to be an accurate theoretical analysis. Early life Karl von Frisch was the son of the surgeon and urologist Anton von Frisch (1849–1917), by his marriage to Marie Exner. Karl was the youngest of four sons, all of whom became university professors. Von Frisch was of partial Jewish heritage. Karl studied in Vienna under Hans Leo Przibram and in Munich under Richard von Hertwig, initially in the field of med ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Autumn
Autumn, also known as fall in American English and Canadian English, is one of the four temperate seasons on Earth. Outside the tropics, autumn marks the transition from summer to winter, in September ( Northern Hemisphere) or March ( Southern Hemisphere). Autumn is the season when the duration of daylight becomes noticeably shorter and the temperature cools considerably. Day length decreases and night length increases as the season progresses until the Winter Solstice in December (Northern Hemisphere) and June (Southern Hemisphere). One of its main features in temperate climates is the striking change in colour for the leaves of deciduous trees as they prepare to shed. Date definitions Some cultures regard the autumnal equinox as "mid-autumn", while others with a longer temperature lag treat the equinox as the start of autumn. In the English-speaking world of high latitude countries, autumn traditionally began with Lammas Day and ended around Hallowe'en, the approxima ...

Goethe University Frankfurt
Goethe University (german: link=no, Johann Wolfgang Goethe-Universität Frankfurt am Main) is a university located in Frankfurt am Main, Germany. It was founded in 1914 as a citizens' university, which means it was founded and funded by the wealthy and active liberal citizenry of Frankfurt. The original name was Universität Frankfurt am Main. In 1932, the university's name was extended in honour of one of the most famous native sons of Frankfurt, the poet, philosopher and writer/dramatist Johann Wolfgang von Goethe. The university currently has around 45,000 students, distributed across four major campuses within the city. The university celebrated its 100th anniversary in 2014.

The university is also affiliated with 18 winners of the Gott ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Paleontology
Paleontology (), also spelled palaeontology or palæontology, is the scientific study of life that existed prior to, and sometimes including, the start of the Holocene epoch (roughly 11,700 years before present). It includes the study of fossils to classify organisms and study their interactions with each other and their environments (their paleoecology). Paleontological observations have been documented as far back as the 5th century BC. The science became established in the 18th century as a result of Georges Cuvier's work on comparative anatomy, and developed rapidly in the 19th century. The term itself originates from Greek (, "old, ancient"), (, ( gen. ), "being, creature"), and (, "speech, thought, study"). Paleontology lies on the border between biology and geology, but differs from archaeology in that it excludes the study of anatomically modern humans. It now uses techniques drawn from a wide range of sciences, including biochemistry, mathematics, and engineering. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Vertebrate
Vertebrates () comprise all animal taxa within the subphylum Vertebrata () ( chordates with backbones), including all mammals, birds, reptiles, amphibians, and fish. Vertebrates represent the overwhelming majority of the phylum Chordata, with currently about 69,963 species described. Vertebrates comprise such groups as the following: * jawless fish, which include hagfish and lampreys * jawed vertebrates, which include: ** cartilaginous fish (sharks, rays, and ratfish) ** bony vertebrates, which include: *** ray-fins (the majority of living bony fish) *** lobe-fins, which include: **** coelacanths and lungfish **** tetrapods (limbed vertebrates) Extant vertebrates range in size from the frog species ''Paedophryne amauensis'', at as little as , to the blue whale, at up to . Vertebrates make up less than five percent of all described animal species; the rest are invertebrates, which lack vertebral columns. The vertebrates traditionally include the hagfish, which do no ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fossil
A fossil (from Classical Latin , ) is any preserved remains, impression, or trace of any once-living thing from a past geological age. Examples include bones, shells, exoskeletons, stone imprints of animals or microbes, objects preserved in amber, hair, petrified wood and DNA remnants. The totality of fossils is known as the ''fossil record''. Paleontology is the study of fossils: their age, method of formation, and evolutionary significance. Specimens are usually considered to be fossils if they are over 10,000 years old. The oldest fossils are around 3.48 billion years old to 4.1 billion years old. Early edition, published online before print. The observation in the 19th century that certain fossils were associated with certain rock strata led to the recognition of a geological timescale and the relative ages of different fossils. The development of radiometric dating techniques in the early 20th century allowed scientists to quantitatively measure the ...

Hochschule
' (, plural: ') is the generic term in German for institutions of higher education, corresponding to ''universities'' and ''colleges'' in English. The term ''Universität'' (plural: ''Universitäten'') is reserved for institutions with the right to confer doctorates. In contrast, ''Hochschule'' encompasses ''Universitäten'' as well as institutions that are not authorized to confer doctorates. Roughly equivalent terms to ''Hochschule'' are used in some other European countries, such as ''högskola'' in Sweden and Finland, ''hogeschool'' in the Netherlands and Flanders, and ' (literally "main school") in Hungary, as well as in post-Soviet countries (deriving from высшее учебное заведение) in Central Europe, in Bulgaria ( висше училище) and Romania. Generic term The German education system knows two different types of universities, which do not have the same legal status. The term ''Hochschule'' can be used to refer to all institutions of higher e ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mine Tailings
In mining, tailings are the materials left over after the process of separating the valuable fraction from the uneconomic fraction (gangue) of an ore. Tailings are different to overburden, which is the waste rock or other material that overlies an ore or mineral body and is displaced during mining without being processed. The extraction of minerals from ore can be done two ways: placer mining, which uses water and gravity to concentrate the valuable minerals, or hard rock mining, which pulverizes the rock containing the ore and then relies on chemical reactions to concentrate the sought-after material. In the latter, the extraction of minerals from ore requires comminution, i.e., grinding the ore into fine particles to facilitate extraction of the target element(s). Because of this comminution, tailings consist of a slurry of fine particles, ranging from the size of a grain of sand to a few micrometres. Mine tailings are usually produced from the mill in slurry form, which is ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Arthur Löwenstamm
Arthur Löwenstamm (also spelt Loewenstamm) (20 December 1882– 22 April 1965) was a Jewish theologian, writer and rabbi in Berlin and in London, where he came in 1939 as a refugee from Nazi Germany. He was the last rabbi of the Jewish community of Spandau, Germany, which comprised 600 members in 1933. Early life and education Arthur Löwenstamm was born on 20 December 1882 in Ratibor, Upper Silesia, German Empire, which is now Racibórz in southern Poland. His parents were Natan Löwenstamm (1856–1937), a shopkeeper, and his wife Johanna Zweig (1851–1936). He was the eldest in the family and had a brother, Kurt (1883–1965, whose son Heinz A. Lowenstam became a noted paleoecologist and great-granddaughter Lisa Goldstein also became a rabbi), a sister, Gertrud, and another brother, Ernest (1887–1888). Löwenstamm attended the Royal Gymnasium in Beuthen (now Bytom), Upper Silesia, from 1893 to 1902. He studied philosophy at the University of Wrocław and completed hi ...

World War I
World War I (28 July 1914 11 November 1918), often abbreviated as WWI, was one of the deadliest global conflicts in history. Belligerents included much of Europe, the Russian Empire, the United States, and the Ottoman Empire, with fighting occurring throughout Europe, the Middle East, Africa, the Pacific, and parts of Asia. An estimated 9 million soldiers were killed in combat, plus another 23 million wounded, while 5 million civilians died as a result of military action, hunger, and disease. Millions more died in genocides within the Ottoman Empire and in the 1918 influenza pandemic, which was exacerbated by the movement of combatants during the war. Prior to 1914, the European great powers were divided between the Triple Entente (comprising France, Russia, and Britain) and the Triple Alliance (containing Germany, Austria-Hungary, and Italy). Tensions in the Balkans came to a head on 28 June 1914, following the assassination of Archduke Franz Ferdin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
