Johann Hieronymus Schröter
Johann Hieronymus Schröter (30 August 1745, Erfurt – 29 August 1816, Lilienthal) was a German astronomer. Life Schröter was born in Erfurt, and studied law at Göttingen University from 1762 until 1767, after which he started a ten-year-long legal practice. In 1777 he was appointed Secretary of the Royal Chamber of George III in Hanover, where he made the acquaintance of two of William Herschel's brothers. In 1779, he acquired a three-foot-long (91 cm, almost one metre) achromatic refractor with lens (50 mm) to observe the Sun, Moon, and Venus. Herschel's discovery of Uranus in 1781 inspired Schröter to pursue astronomy more seriously, and he resigned his post and became chief magistrate and district governor of Lilienthal. In 1784, he paid 31 Reichsthaler (about 600 Euros of today) for a Herschel reflector of 122 cm focal length and 12 cm aperture. He quickly gained a good name from his observational reports in journals, but was not satisfie ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Mars
Mars is the fourth planet from the Sun. It is also known as the "Red Planet", because of its orange-red appearance. Mars is a desert-like rocky planet with a tenuous carbon dioxide () atmosphere. At the average surface level the atmospheric pressure is a few thousandths of Earth's, atmospheric temperature ranges from and cosmic radiation is high. Mars retains some water, in the ground as well as thinly in the atmosphere, forming cirrus clouds, frost, larger polar regions of permafrost and ice caps (with seasonal snow), but no liquid surface water. Its surface gravity is roughly a third of Earth's or double that of the Moon. It is half as wide as Earth or twice the Moon, with a diameter of , and has a surface area the size of all the dry land of Earth. Fine dust is prevalent across the surface and the atmosphere, being picked up and spread at the low Martian gravity even by the weak wind of the tenuous atmosphere. The terrain of Mars roughly follows a north-south ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

The Royal Society
The Royal Society, formally The Royal Society of London for Improving Natural Knowledge, is a learned society and the United Kingdom's national academy of sciences. The society fulfils a number of roles: promoting science and its benefits, recognising excellence in science, supporting outstanding science, providing scientific advice for policy, education and public engagement and fostering international and global co-operation. Founded on 28 November 1660, it was granted a royal charter by King Charles II and is the oldest continuously existing scientific academy in the world. The society is governed by its Council, which is chaired by the society's president, according to a set of statutes and standing orders. The members of Council and the president are elected from and by its Fellows, the basic members of the society, who are themselves elected by existing Fellows. , there are about 1,700 fellows, allowed to use the postnominal title FRS (Fellow of the Royal Society) ...

Dominique Vandamme
General Dominique-Joseph René Vandamme, Count of Unseburg (; 5 November 1770, in Cassel, Nord – 15 July 1830) was a French military officer, who fought in the Napoleonic Wars. He was a dedicated career soldier with a reputation as an excellent division and corps commander. However, he had a nasty disposition that alienated his colleagues, and would publicly criticize Napoleon, who never appointed him marshal. Biography Vandamme enlisted in the army in 1786 and rapidly rose through the ranks. At the outbreak of the French Revolutionary Wars in 1793 he was a Brigadier General. He served in this rank in the campaigns of 1794 in the Low Countries, 1795 on the Rhine and 1796 in Germany. He was court-martialled for looting and suspended. Reinstated, he fought at the First Battle of Stockach on 25 March 1799, but disagreement with General Jean Moreau led to his being sent to occupation duties in Holland. At the Battle of Austerlitz in 1805, he led his division, alongside Gen. S ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Friedrich Wilhelm Bessel
Friedrich Wilhelm Bessel (; 22 July 1784 – 17 March 1846) was a German astronomer, mathematician, physicist, and geodesist. He was the first astronomer who determined reliable values for the distance from the Sun to another star by the method of parallax. Certain important mathematical functions were first studied systematically by Bessel and were named Bessel functions in his honour. Life and family Bessel was born in Minden, Westphalia, then capital of the Prussian administrative region Minden-Ravensberg, as second son of a civil servant into a large family. At the age of 14 he left the school, because he did not like the education in Latin language, and apprenticed in the import-export concern Kulenkamp at Bremen. The business's reliance on cargo ships led him to turn his mathematical skills to problems in navigation. This in turn led to an interest in astronomy as a way of determining longitude. Bessel came to the attention of Heinrich Wilhelm Olbers, a practising phy ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Karl Ludwig Harding
Karl Ludwig Harding (29 September 1765 – 31 August 1834) was a German astronomer, who discovered 3 Juno, Juno, the third asteroid of the main-belt in 1804. Life and career Harding was born in Lauenburg. From 1786–1789, he was educated at the University of Göttingen, where he studied theology, mathematics, and physics. In 1796, Johann Hieronymus Schröter hired Harding as a tutor for his son. Schröter was an enthusiastic astronomer and owner of a well-equipped observatory in Lilienthal, Lower Saxony, Lilienthal near Bremen, where Harding was soon appointed observer and inspector. In 1800, he was among the 24 astronomers invited to participate in the celestial police, a group dedicated to finding additional planets in the Solar System. As part of the group, in 1804, Harding discovered Juno at Schröter's observatory. In the next year he left Lilienthal, where his successor became Friedrich Bessel, Friedrich Wilhelm Bessel, as he was appointed extraordinary professor of a ...
