Elisabeth Von Matt
Elisabeth von Matt (1762–1814) was an Austrian astronomer active in the late 18th and early 19th century who is regarded as the only female scientist to have her observations published in European astronomy journals during the period. She worked primarily in positional astronomy, documenting the asteroids Pallas and Juno. Life Elisabeth von Matt (née Humelauer) was a baroness living in Vienna. There, she built a private observatory and ordered the equipment needed to observe the sky. Her observations were published in Bode's '' Astronomisches Jahrbuch'' and Franz Xaver von Zach's ''Monatliche Correspondenz''. In addition to her own contributions to measurements at the time, von Matt supported the advancement of the field of astronomy by opening her observatory to Johann Tobias Bürg, who was her mentor, and assisting in the supply of books and instruments in the community. Legacy Austrian botanist Josef August Schultes named the plant genus ''Mattia'' in honor of von M ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rindera
''Rindera'' is a genus of flowering plants belonging to the family Boraginaceae. Its native range is north-western Africa (Algeria), south-eastern and eastern Europe (Greece, East European Russia, Romania, Ukraine and Yugoslavia) to western and central Asia (Afghanistan, Altay, Bulgaria, Iran, Iraq, Kazakhstan, Kyrgyzstan, Krasnoyarsk, Crimia, Lebanon-Syria, Mongolia, North Caucasus, South European Russia, Tajikistan, Transcaucasus, Turkey, Turkmenistan, Uzbekistan) and Xinjiang (China).

18th-century Austrian 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.

Vienna Observatory
The Vienna Observatory (german: Universitätssternwarte Wien) is an astronomical observatory in Vienna, Austria. It is part of the University of Vienna. The first observatory was built in 1753–1754 on the roof of one of the university buildings. A new observatory was built between 1874 and 1879, and was finally inaugurated by Emperor Franz Joseph I of Austria in 1883. The main dome houses a refractor with a diameter of and a focal length of built by the Grubb Telescope Company. At that time, it was the world's largest refracting telescope. Land for the new observatory was purchased in 1872, and was noted for having increased elevations (about 150 ft) above the city. Construction started in March 1874, and it was opened with new instruments in 1877. The overall design had various rooms and three main domes, one for the Grubb refractor and then two smaller domes, and some terraces. At this time there were larger aperture reflecting telescopes, and the main technologies o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
John Arnold (watchmaker)
John Arnold (1736 – 11 August 1799) was an English watchmaker and inventor. John Arnold was the first to design a watch that was both practical and accurate, and also brought the term "chronometer" into use in its modern sense, meaning a precision timekeeper. His technical advances enabled the quantity production of marine chronometers for use on board ships from around 1782. The basic design of these has remained, with a few modifications unchanged until the late twentieth century. His legacy includes, together with Abraham-Louis Breguet, as one of the inventors of the modern mechanical watch. One of his most important inventions, the overcoil balance spring is still used in most mechanical wristwatches. It was from around 1770 that Arnold developed the portable precision timekeeper, almost from the point where John Harrison ended his work in this field. But, compared to Harrison's complicated and expensive watch, Arnold's basic design was simple whilst consistently accurate ...

Edward Troughton
Edward Troughton FRS FRSE FAS (October 1753 – 12 June 1835) was a British instrument maker who was notable for making telescopes and other astronomical instruments. Life Troughton was born at Corney, Cumberland, the youngest of six children to Francis Troughton, a husbandman on a farm, and his wife, Mary Stable. Originally raised to tend animals, Edward went to London in 1773. He then served an apprenticeship with his uncle, John Troughton (b.c.1716) alongside his elder brother, also John Troughton, and in 1779 he became his business partner and soon established himself as the top maker of navigational, surveying and astronomical instruments in Britain. They were based at 136 Fleet Street in central London. Their shop was called the "Sign of the Orrery". In 1795 he delivered what is now known as the Troughton Equatorial telescope to the Armagh Observatory, a 2-inch aperture refractor telescope mounted equatorially, and its first major instrument since its founding in 179 ...

Cornelis Johannes Van Houten
Cornelis Johannes van Houten (18 February 1920 – 24 August 2002) was a Dutch astronomer, sometimes referred to as Kees van Houten. Early life and education Born in The Hague, he spent his entire career at Leiden University except for a brief period (1954–1956) as research assistant at Yerkes Observatory. Family He married fellow astronomer Ingrid Groeneveld (who became Ingrid van Houten-Groeneveld) and together they became interested in asteroids. They had one son, Karel. Work as astronomer In a jointly credited trio with Tom Gehrels and Ingrid, he was an extremely prolific discoverer of many thousands of asteroids. Gehrels did a sky survey using the 48-inch Schmidt telescope at Palomar Observatory and shipped the plates to the van Houtens at Leiden Observatory, who analyzed them for new asteroids. The trio are jointly credited with several thousand discoveries. When the orbit of an asteroid is determined, it can be classified as an Apollo asteroid (e.g. 1862 Apollo), an ...

Boraginaceae
Boraginaceae, the borage or forget-me-not family, includes about 2,000 species of shrubs, trees and herbs in 146, to 156 genera with a worldwide distribution. The APG IV system from 2016 classifies the Boraginaceae as single family of the order Boraginales within the asterids. Under the older Cronquist system it was included in Lamiales, but it is now clear that it is no more similar to the other families in this order than they are to families in several other asterid orders. A revision of the Boraginales, also from 2016, split the Boraginaceae in eleven distinct families: Boraginaceae ''sensu stricto'', Codonaceae, Coldeniaceae, Cordiaceae, Ehretiaceae, Heliotropiaceae, Hoplestigmataceae, Hydrophyllaceae, Lennoaceae, Namaceae, and Wellstediaceae. These plants have alternately arranged leaves, or a combination of alternate and opposite leaves. The leaf blades usually have a narrow shape; many are linear or lance-shaped. They are smooth-edged or toothed, and some have petiol ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Flowering Plant
Flowering plants are plants that bear flowers and fruits, and form the clade Angiospermae (), commonly called angiosperms. The term "angiosperm" is derived from the Greek words ('container, vessel') and ('seed'), and refers to those plants that produce their seeds enclosed within a fruit. They are by far the most diverse group of land plants with 64 orders, 416 families, approximately 13,000 known genera and 300,000 known species. Angiosperms were formerly called Magnoliophyta (). Like gymnosperms, angiosperms are seed-producing plants. They are distinguished from gymnosperms by characteristics including flowers, endosperm within their seeds, and the production of fruits that contain the seeds. The ancestors of flowering plants diverged from the common ancestor of all living gymnosperms before the end of the Carboniferous, over 300 million years ago. The closest fossil relatives of flowering plants are uncertain and contentious. The earliest angiosperm fossils ar ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
