Heinrich Wilhelm Brandes
Heinrich Wilhelm Brandes (; 27 July 1777 – 17 May 1834) was a German physicist, meteorologist, and astronomer. Brandes was born in 1777 in Groden near Ritzebüttel (a former exclave of the Free Imperial City of Hamburg, today in Cuxhaven), the third son of Albert Georg Brandes, a preacher. He studied at the University of Göttingen from 1796 to 1798 under Abraham Gotthelf Kästner and Georg Christoph Lichtenberg. Carl Friedrich Gauss was a fellow student. He attained his doctorate in 1800, and spent a short time teaching privately. As an astronomer, he was noted for demonstrating that meteors occur in the upper atmosphere and thus not really a meteorological phenomenon. From 1801 to 1811 he was at first a technical designer of dykes on the Weser river at Eckwarden, Butjadingen, in the Duchy of Oldenburg, and later a dyke inspector for the lower right bank of the Weser. In 1811 he became a professor of mathematics at the newly created University of Breslau, a merger of two Wr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
University Of Breslau
A university () is an institution of higher (or tertiary) education and research which awards academic degrees in several academic disciplines. Universities typically offer both undergraduate and postgraduate programs. In the United States, the designation is reserved for colleges that have a graduate school. The word ''university'' is derived from the Latin ''universitas magistrorum et scholarium'', which roughly means "community of teachers and scholars". The first universities were created in Europe by Catholic Church monks. The University of Bologna (''Università di Bologna''), founded in 1088, is the first university in the sense of: *Being a high degree-awarding institute. *Having independence from the ecclesiastic schools, although conducted by both clergy and non-clergy. *Using the word ''universitas'' (which was coined at its foundation). *Issuing secular and non-secular degrees: grammar, rhetoric, logic, theology, canon law, notarial law.Hunt Janin: "The university ...

18th-century German Astronomers
The 18th century lasted from January 1, 1701 ( MDCCI) to December 31, 1800 ( MDCCC). During the 18th century, elements of Enlightenment thinking culminated in the American, French, and Haitian Revolutions. During the century, slave trading and human trafficking expanded across the shores of the Atlantic, while declining in Russia, China, and Korea. Revolutions began to challenge the legitimacy of monarchical and aristocratic power structures, including the structures and beliefs that supported slavery. The Industrial Revolution began during mid-century, leading to radical changes in human society and the environment. Western historians have occasionally defined the 18th century otherwise for the purposes of their work. For example, the "short" 18th century may be defined as 1715–1789, denoting the period of time between the death of Louis XIV of France and the start of the French Revolution, with an emphasis on directly interconnected events.

19th-century German Physicists
The 19th (nineteenth) century began on 1 January 1801 ( MDCCCI), and ended on 31 December 1900 ( MCM). The 19th century was the ninth century of the 2nd millennium. The 19th century was characterized by vast social upheaval. Slavery was abolished in much of Europe and the Americas. The First Industrial Revolution, though it began in the late 18th century, expanding beyond its British homeland for the first time during this century, particularly remaking the economies and societies of the Low Countries, the Rhineland, Northern Italy, and the Northeastern United States. A few decades later, the Second Industrial Revolution led to ever more massive urbanization and much higher levels of productivity, profit, and prosperity, a pattern that continued into the 20th century. The Islamic gunpowder empires fell into decline and European imperialism brought much of South Asia, Southeast Asia, and almost all of Africa under colonial rule. It was also marked by the collapse of the la ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Johann Friedrich Benzenberg
Johann Friedrich Benzenberg (5 May 1777 – 7 June 1846) was a German astronomer, geologist, and physicist. Biography Benzenberg was born near Elberfeld, Germany on 5 May 1777 to Heinrich Benzenberg and Johanna Elisabeth. He married Charlotte Platzhoff in 1807. After studying theology at Herborn and Marburg, he travelled to Göttingen where he became interested in science through attending lectures by Georg Christoph Lichtenberg and Abraham Gotthelf Kästner. Benzenberg obtained a PhD from the University of Duisburg in 1800 and became a professor of mathematics at the women's college of Düsseldorf in 1805. After the Napoleonic occupation of Germany he immigrated to Switzerland where he became interested in politics. Benzenberg's interest in politics led him to write extensively on issues such as the constitution of Prussia. In 1844 Benzenberg built a private observatory, the Düsseldorf-Bilk Observatory, in Bilk, which he later donated to the city along with a grant to pay for ...

Alter Johannisfriedhof
The Alter Johannisfriedhof ("Old St. John's Cemetery") is the oldest burial ground in the city of Leipzig, Germany. It began in 1278, as part of the ''Johannishospital'' (St. John's Hospital) in Leipzig, a leper hospital. It was later attached to the ''Johanniskirche'' (St. John's Church), which was destroyed in World War II. In 1536 it became the common burial ground for the city of Leipzig, and expanded several times. It was also re-modeled in the style of the Camposanto in Pisa, a popular style of cemetery in Germany. In 1680 and 1805 the graveyard was expanded by the additions of sections three and four respectively, then the fifth and the final extension took place between 1827 and 1863. 1883 saw its last burial. In 1981 the graveyard was closed and comprehensively cleared. Fifty-eight monuments and gravestones from the former Neuer Johannisfriedhof, which had similarly been cleared and re-developed as the present Friedenspark, were set up in the south-eastern corner of ...

Euler–Mascheroni Constant
Euler's constant (sometimes also called the Euler–Mascheroni constant) is a mathematical constant usually denoted by the lowercase Greek letter gamma (). It is defined as the limiting difference between the harmonic series and the natural logarithm, denoted here by \log: :\begin \gamma &= \lim_\left(-\log n + \sum_^n \frac1\right)\\ px&=\int_1^\infty\left(-\frac1x+\frac1\right)\,dx. \end Here, \lfloor x\rfloor represents the floor function. The numerical value of Euler's constant, to 50 decimal places, is: : History The constant first appeared in a 1734 paper by the Swiss mathematician Leonhard Euler, titled ''De Progressionibus harmonicis observationes'' (Eneström Index 43). Euler used the notations and for the constant. In 1790, Italian mathematician Lorenzo Mascheroni used the notations and for the constant. The notation appears nowhere in the writings of either Euler or Mascheroni, and was chosen at a later time perhaps because of the constant's connecti ...

Synoptic Meteorology
The synoptic scale in meteorology (also known as large scale or cyclonic scale) is a horizontal length scale of the order of 1000 kilometers (about 620 miles) or more. This corresponds to a horizontal scale typical of mid-latitude depressions (e.g., extratropical cyclones). Most high- and low-pressure areas seen on weather maps (such as surface weather analyses) are synoptic-scale systems, driven by the location of Rossby waves in their respective hemisphere. Low-pressure areas and their related frontal zones occur on the leading edge of a trough within the Rossby wave pattern, while high-pressure areas form on the back edge of the trough. Most precipitation areas occur near frontal zones. The word ''synoptic'' is derived from the Greek word ('), meaning ''seen together''. The Navier–Stokes equations applied to atmospheric motion can be simplified by scale analysis in the synoptic scale. It can be shown that the main terms in horizontal equations are Coriolis force an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
