Alois Von Beck Widmanstätten
Count Alois von Beckh Widmanstätten (13 July 1754 – 10 June 1849) was a printer and mineralogist from the Holy Roman Empire and then the Austrian Empire. His name is sometimes given as Alois von Beckh-Widmannstätten or Aloys Joseph Franz Xaver Beck Edler von Widmanstätten. He is known for recognizing a unique pattern of cross-hatching lines on the surface of iron-rich meteorites, now called Widmanstätten patterns, resulting from the cooling and crystallization of interstitial minerals. A crater on the Moon is named after Widmanstätten. Working life Von Widmanstätten was born in Graz where his family had a printing business and was trained in the printing art by his father. His family owned exclusive printing rights in the Steiermark province, but this was lost in 1784 and Alois sold the business in 1807. In 1804, he ran a spinning mill in Pottendorf, Austria.

Holy Roman Empire
The Holy Roman Empire, also known as the Holy Roman Empire of the German Nation after 1512, was a polity in Central and Western Europe, usually headed by the Holy Roman Emperor. It developed in the Early Middle Ages, and lasted for a millennium until its Dissolution of the Holy Roman Empire, dissolution in 1806 during the Napoleonic Wars. For most of its history the Empire comprised the entirety of the modern countries of Germany, Czechia, Austria, the Netherlands, Belgium, Switzerland, Slovenia, and Luxembourg, most of north-central Italy, and large parts of modern-day east France and west Poland. On 25 December 800, Pope Leo III crowned the Frankish king Charlemagne Roman emperor, reviving the title more than three centuries after the fall of the Western Roman Empire in 476. The title lapsed in 924, but was revived in 962 when Otto I, OttoI was crowned emperor by Pope John XII, as Charlemagne's and the Carolingian Empire's successor. From 962 until the 12th century, the empire ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Krasnojarsk (meteorite)
Krasnojarsk was the first pallasite meteorite ever found. History A mass of about was detected in 1749 about 145 miles south of Krasnoyarsk.The meteorite was found in 1749 by the local blacksmith Yakov Medvedev and the mining foreman IK Mettikh who reported the find near the village of Medvedevo (the current territory of the Komsky Rural Council of the Novosyolovsky district of the Krasnoyarsk Krai). In 1772, the unusual block was shown to Academician P.S.Pallas, who at that time was in those parts with an expedition. On his instructions, the bulk of the lump, weighing about 40 pounds, was sent in 1773 to St. Petersburg, and in 1777 - delivered to the Kunstkamera.

Meteorite Researchers
A meteorite is a rock that originated in outer space and has fallen to the surface of a planet or moon. When the original object enters the atmosphere, various factors such as friction, pressure, and chemical interactions with the atmospheric gases cause it to heat up and radiate energy. It then becomes a meteor and forms a fireball, also known as a shooting star; astronomers call the brightest examples " bolides". Once it settles on the larger body's surface, the meteor becomes a meteorite. Meteorites vary greatly in size. For geologists, a bolide is a meteorite large enough to create an impact crater. Meteorites that are recovered after being observed as they transit the atmosphere and impact Earth are called meteorite falls. All others are known as meteorite finds. Meteorites have traditionally been divided into three broad categories: stony meteorites that are rocks, mainly composed of silicate minerals; iron meteorites that are largely composed of ferronickel; and stony ...

Counts Of Austria
Count (feminine: countess) is a historical title of nobility in certain European countries, varying in relative status, generally of middling rank in the hierarchy of nobility. Pine, L. G. ''Titles: How the King Became His Majesty''. New York: Barnes & Noble, 1992. p. 73. . Especially in earlier medieval periods the term often implied not only a certain status, but also that the ''count'' had specific responsibilities or offices. The etymologically related English term "county" denoted the territories associated with some countships, but not all. The title of ''count'' is typically not used in England or English-speaking countries, and the term ''earl'' is used instead. A female holder of the title is still referred to as a ''countess'', however. Origin of the term The word ''count'' came into English from the French ', itself from Latin '—in its accusative form ''comitem''. It meant "companion" or "attendant", and as a title it indicated that someone was delegated to re ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Scientists From The Austrian Empire
A scientist is a person who researches to advance knowledge in an area of the natural sciences. In classical antiquity, there was no real ancient analog of a modern scientist. Instead, philosophers engaged in the philosophical study of nature called natural philosophy, a precursor of natural science. Though Thales ( 624–545 BC) was arguably the first scientist for describing how cosmic events may be seen as natural, not necessarily caused by gods,Frank N. Magill''The Ancient World: Dictionary of World Biography'', Volume 1 Routledge, 2003 it was not until the 19th century that the term ''scientist'' came into regular use after it was coined by the theologian, philosopher, and historian of science William Whewell in 1833. History The roles of "scientists", and their predecessors before the emergence of modern scientific disciplines, have evolved considerably over time. Scientists of different eras (and before them, natural philosophers, mathematicians, natur ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
