Christel Hamann
Christel Bernhard Julius Hamann (born February 27, 1847 in Hammelwarden, Oldenburg – died June 9, 1948 in Berlin, Germany) was a German-born inventor of Computing Machines. Early life and education Hamann's father was an Oldenburg border guard and ambassador in Ellwitz. Hamann completed an apprenticeship as a mechanic at the Nautical Institute in Bremerhaven and visited the pilot school there. Afterwards he attended the mathematical-mechanical institute of A. Ott in Kempten (Allgäu) in the workshops of Carl Zeiss in Jena and in the workshop of Carl Bamberg in Berlin. Career In 1896 he founded the Mathematical-Mechanical Institute in Berlin-Friedenau, where he developed and built mathematical instruments and surveying instruments. In 1900, he received the gold medal for his instruments at the World Exposition in Paris. Around 1889 he developed the calculation machines Gauss and Berolina inspired in part by the Gauss computing machine of Gottfried Wilhelm Leibniz G ...

Oldenburg Land
Oldenburg Land (german: Oldenburger Land) is a region and regional association in the German state of Lower Saxony in the area of the former Grand Duchy of Oldenburg (1815–1918), the later Free State of Oldenburg (1918–1946) and administrative district of Oldenburg (1946 to 1978), without its exclaves, along the rivers Hunte and Hase. In the region between Waterkant, Dümmer and Damme Hills some of the population still speak Low German today and, in Saterland also Saterland Frisian. The region is rich in old Lower Saxon customs such as ''Schützenfests'' or '' Kohlfahrten''. Typical country sports include '' Klootschießen'' and ''Boßeln''. The mainly Catholic southern part of the Oldenburg Land is known as Oldenburg Münsterland, the mainly Lutheran northern part is known as Oldenburg Land (''Old Oldenburg'') in its narrower sense. In terms of Germany's modern administrative districts, Oldenburg Land roughly corresponds to Ammerland, Cloppenburg, Delmenhorst, Friesland, ...

Difference Engine
A difference engine is an automatic mechanical calculator designed to tabulate polynomial, polynomial functions. It was designed in the 1820s, and was first created by Charles Babbage. The name, the difference engine, is derived from the method of divided differences, a way to interpolate or tabulate functions by using a small set of polynomial co-efficients. Some of the most common mathematical functions used in engineering, science and navigation, were, and still are computable with the use of the difference engine's capability of computing logarithmic and trigonometric functions, which can be Taylor series, approximated by polynomials, so a difference engine can compute many useful mathematical table, tables of numbers. History The notion of a mechanical calculator for mathematical functions can be traced back to the Antikythera mechanism of the 2nd century BC, while early modern examples are attributed to Blaise Pascal, Pascal and Gottfried Leibniz, Leibniz in the 17th ce ...

Men Centenarians
A man is an adult male human. Prior to adulthood, a male human is referred to as a boy (a male child or adolescent). Like most other male mammals, a man's genome usually inherits an X chromosome from the mother and a Y chromosome from the father. Sex differentiation of the male fetus is governed by the SRY gene on the Y chromosome. During puberty, hormones which stimulate androgen production result in the development of secondary sexual characteristics, thus exhibiting greater differences between the sexes. These include greater muscle mass, the growth of facial hair and a lower body fat composition. Male anatomy is distinguished from female anatomy by the male reproductive system, which includes the penis, testicles, sperm duct, prostate gland and the epididymis, and by secondary sex characteristics, including a narrower pelvis, narrower hips, and smaller breasts without mammary glands. Throughout human history, traditional gender roles have often defined ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Heinrich Wilhelm Matthias Olbers
Heinrich Wilhelm Matthias Olbers (; ; 11 October 1758 – 2 March 1840) was a German physician and astronomer. Life and career Olbers was born in Arbergen, Germany, today part of Bremen, and studied to be a physician at Göttingen (1777–80). While he was at Göttingen, he studied mathematics with Abraham Gotthelf Kästner. In 1779, while attending to a sick fellow student, he devised a method of calculating cometary orbits which made an epoch in the treatment of the subject. It was the first satisfactory method of calculating cometary orbits. After his graduation in 1780, he began practicing medicine in Bremen. At night he dedicated his time to astronomical observation, making the upper story of his home into an observatory. In 1800, Olbers was one of 24 astronomers invited to participate in the group known as the "celestial police", dedicated to finding new planets in the solar system. On 28 March 1802, Olbers discovered and named the asteroid Pallas. Five years later, on ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
