Václav Jeřábek
Václav Jeřábek (1845–1931) was a Czech mathematician, specialized in constructive geometry. Life and work Jeřábek studied at the lower school of Pardubice and at the higher school of Písek, then he was to Vienna and studied at Imperial and Royal Polytechnic Institute where he graduated. Although he participated in several leading intellectual circles of Vienna, he remained a Czech with a clear view of patriotism. He began his teaching at the ''Realschule'' of Litomyšl (1870), being transferred two years after to the ''Realschule'' of Telč. In 1881, he was appointed professor of the ''Czech Realschule'' in Brno, and became its director in 1901. He retired in 1907, and suffering of a cataract, he died almost completely blind, MacTutor History of Mathematics. in 1931. Jeřábek was one of the men who kept the Czech geometry at the scientific level. He published scientific articles in Czech, German and French, and longer lectures. He is well remembered by the Jerabek hype ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pardubice Region
Pardubice Region ( cs, Pardubický kraj; , ; pl, Kraj pardubicki) is an administrative unit ( cs, kraj) of the Czech Republic, located mainly in the eastern part of its historical region of Bohemia, with a small part in northwestern Moravia.

Austro-Hungarian Mathematicians
Austria-Hungary, often referred to as the Austro-Hungarian Empire,, the Dual Monarchy, or Austria, was a constitutional monarchy and great power in Central Europe between 1867 and 1918. It was formed with the Austro-Hungarian Compromise of 1867 in the aftermath of the Austro-Prussian War and was dissolved shortly after its defeat in the First World War. Austria-Hungary was ruled by the House of Habsburg and constituted the last phase in the constitutional evolution of the Habsburg monarchy. It was a multinational state and one of Europe's major powers at the time. Austria-Hungary was geographically the second-largest country in Europe after the Russian Empire, at and the third-most populous (after Russia and the German Empire). The Empire built up the fourth-largest machine building industry in the world, after the United States, Germany and the United Kingdom. Austria-Hungary also became the world's third-largest manufacturer and exporter of electric home appliances, el ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
19th-century Czech People
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 lar ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bohemia
Bohemia ( ; cs, Čechy ; ; hsb, Čěska; szl, Czechy) is the westernmost and largest historical region of the Czech Republic. Bohemia can also refer to a wider area consisting of the historical Lands of the Bohemian Crown ruled by the Bohemian kings, including Moravia and Czech Silesia, in which case the smaller region is referred to as Bohemia proper as a means of distinction. Bohemia was a duchy of Great Moravia, later an independent principality, a kingdom in the Holy Roman Empire, and subsequently a part of the Habsburg monarchy and the Austrian Empire. After World War I and the establishment of an independent Czechoslovak state, the whole of Bohemia became a part of Czechoslovakia, defying claims of the German-speaking inhabitants that regions with German-speaking majority should be included in the Republic of German-Austria. Between 1938 and 1945, these border regions were joined to Nazi Germany as the Sudetenland. The remainder of Czech territory became the Second ...

Moravia ( , also , ; cs, Morava ; german: link=yes, Mähren ; pl, Morawy ; szl, Morawa; la, Moravia) is a historical region in the east of the Czech Republic and one of three historical Czech lands, with Bohemia and Czech Silesia. The medieval and early modern Margraviate of Moravia was a crown land of the Lands of the Bohemian Crown from 1348 to 1918, an imperial state of the Holy Roman Empire from 1004 to 1806, a crown land of the Austrian Empire from 1804 to 1867, and a part of Austria-Hungary from 1867 to 1918. Moravia was one of the five lands of Czechoslovakia founded in 1918.

Union Of Czech Mathematicians And Physicists
The Union of Czech mathematicians and physicists ( cs, Jednota českých matematiků a fyziků, JČMF) is one of the oldest learned societies in Czech lands existing to this day. It was founded in 1862 as the Association for free lectures in mathematics and physics (Union of Czech mathematicians). From the beginning, its goal was improvement of teaching physics and mathematics at schools on all levels and of all types and further support and promote the development of those sciences. As a consequence of patriotic efforts, the Association was enlarged in 1869 into the Union of Czech mathematicians and physicists. Members of the Union were largely teachers at high schools and post-secondary learning institutes, and further professors at universities and scientists. In 1870, the Union started publishing the ''News of the Union of Czech mathematicians and physicists'', which in 1872 gave rise to the ''Journal for fostering mathematics and physics'' (Czech: ''Časopis pro pěstování ma ...

Euler Line
In geometry, the Euler line, named after Leonhard Euler (), is a line determined from any triangle that is not equilateral. It is a central line of the triangle, and it passes through several important points determined from the triangle, including the orthocenter, the circumcenter, the centroid, the Exeter point and the center of the nine-point circle of the triangle. The concept of a triangle's Euler line extends to the Euler line of other shapes, such as the quadrilateral and the tetrahedron. Triangle centers on the Euler line Individual centers Euler showed in 1765 that in any triangle, the orthocenter, circumcenter and centroid are collinear. This property is also true for another triangle center, the nine-point center, although it had not been defined in Euler's time. In equilateral triangles, these four points coincide, but in any other triangle they are all distinct from each other, and the Euler line is determined by any two of them. Other notable points that lie on ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
