Benjamin Bramer
Benjamin Bramer (15 February 1588 – 17 March 1652) was a German mathematician, architect, inventor, and adviser. Early life Bramer was born on 15 February 1588 in Felsberg, Germany to a Protestant minister father. The minister later died when Bramer was three years old. This led him to be adopted by his brother-in-law, Jost Bürgi, who was a prominent mathematician at the time. He moved to Bürgi's home in Kassel Kassel (; in Germany, spelled Cassel until 1926) is a city on the Fulda River in northern Hesse, Germany. It is the administrative seat of the Regierungsbezirk Kassel and the district of the same name and had 201,048 inhabitants in December 2020 ... after being adopted. Bürgi educated Bramer from a young age, particularly in the fields of mathematics and architecture. When Bramer was 16 he stayed in Prague with his foster father after Bürgi was appointed to the imperial court. Bramer would stay there for five years before returning to Kassel to begin his care ...

Felsberg, Germany
Felsberg is a town in the Schwalm-Eder district about south of Kassel. Geography The landscape around Felsberg is marked by hills and small lakes, as well as the remains of gravel quarrying. As part of the West Hesse Depression, it lies in a sunken area that was formed by volcanic activity in the Tertiary subera. The change from partly basaltic hills to smooth river valleys is striking. While the river valleys are covered by fluvial sediments, fertile loess beds can be found higher up. The river Eder flows through Felsberg's municipal area. Near Gensungen lies the Heiligenberg ("Holy Mountain") with the ruins of the Heiligenburg Castle. Constituent communities The town consists of 15 communities: Altenbrunslar, Altenburg, Beuern, Böddiger, Gensungen, Helmshausen, Hesserode, Heßlar, Hilgershausen, Lohre, Melgershausen, Neuenbrunslar, Niedervorschütz, Rhünda and Wolfershausen together with the historic Felsberg, to which the other, formerly independent communities were ...

Rheinfels Castle
Rheinfels Castle (german: Burg Rheinfels) is a castle ruin located above the left (west) bank of the Rhine in Sankt Goar, Germany. It was started in 1245 by Count Diether V of Katzenelnbogen. After expansions, it was the largest fortress in the Middle Rhein Valley between Koblenz and Mainz. It was slighted by French Revolutionary Army troops in 1797. It is the largest castle overlooking the Rhine, and historically covered five times its current area. While much of the castle is a ruin, some of the outer buildings are now a luxury hotel, "wellness" centre, and restaurant. There is also a museum within some of the better preserved structures. Description The main entrance to the castle complex is a tall square clock or gate tower (~1300 AD) opposite the hotel. A connecting path joins the clock tower to the remains of the living quarters of the landgraves of Hesse-Darmstadt (the so-called Darmstadt Building). The Darmstadt building was designed in Tudor style with pointed gable ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
17th-century German Mathematicians
The 17th century lasted from January 1, 1601 ( MDCI), to December 31, 1700 ( MDCC). It falls into the early modern period of Europe and in that continent (whose impact on the world was increasing) was characterized by the Baroque cultural movement, the latter part of the Spanish Golden Age, the Dutch Golden Age, the French ''Grand Siècle'' dominated by Louis XIV, the Scientific Revolution, the world's first public company and megacorporation known as the Dutch East India Company, and according to some historians, the General Crisis. From the mid-17th century, European politics were increasingly dominated by the Kingdom of France of Louis XIV, where royal power was solidified domestically in the civil war of the Fronde. The semi-feudal territorial French nobility was weakened and subjugated to the power of an absolute monarchy through the reinvention of the Palace of Versailles from a hunting lodge to a gilded prison, in which a greatly expanded royal court could be more easily ke ...

1652 Deaths
Year 165 ( CLXV) was a common year starting on Monday (link will display the full calendar) of the Julian calendar. At the time, it was known as the Year of the Consulship of Orfitus and Pudens (or, less frequently, year 918 ''Ab urbe condita''). The denomination 165 for this year has been used since the early medieval period, when the Anno Domini calendar era became the prevalent method in Europe for naming years.

Christoph Scheiner
Christoph Scheiner SJ (25 July 1573 (or 1575) – 18 June 1650) was a Jesuit priest, physicist and astronomer in Ingolstadt. Biography Augsburg/Dillingen: 1591–1605 Scheiner was born in Markt Wald near Mindelheim in Swabia, earlier markgravate Burgau, possession of the House of Habsburg. He attended the Jesuit St. Salvator Grammar School in Augsburg from May 1591 until 24 October 1595. He graduated as a "rhetor" and entered the Jesuit Order in Landsberg am Lech on 26 October 1595. At the local seminary, he served his biennial novitiate (1595–1597) under the tutelage of Novice Master Father Rupert Reindl SJ. From 1597 to 1598, he finished his lower studies of rhetoric in Augsburg. He took his first vows before Father Melchior Stör, SJ and received the minor orders from the Augsburg suffragan bishop Sebastian Breuning. He spent the years 1598–1601 in Ingolstadt studying philosophy ( metaphysics and mathematics). In 1603, Scheiner invented the pantograph, "Lake Co ...

Geometric Perspective
Linear or point-projection perspective (from la, perspicere 'to see through') is one of two types of 3D projection, graphical projection perspective in the graphic arts; the other is parallel projection. Linear perspective is an approximate representation, generally on a flat surface, of an image as it is seen by the eye. Perspective drawing is useful for representing a three-dimensional scene in a two-dimensional medium, like paper. The most characteristic features of linear perspective are that objects appear smaller as their distance from the observer increases, and that they are subject to ''foreshortening'', meaning that an object's dimensions along the line of sight appear shorter than its dimensions across the line of sight. All objects will recede to points in the distance, usually along the horizon line, but also above and below the horizon line depending on the view used.

Pantograph
A pantograph (, from their original use for copying writing) is a mechanical linkage connected in a manner based on parallelograms so that the movement of one pen, in tracing an image, produces identical movements in a second pen. If a line drawing is traced by the first point, an identical, enlarged, or miniaturized copy will be drawn by a pen fixed to the other. Using the same principle, different kinds of pantographs are used for other forms of duplication in areas such as sculpting, minting, engraving, and milling. Because of the shape of the original device, a pantograph also refers to a kind of structure that can compress or extend like an accordion, forming a characteristic rhomboidal pattern. This can be found in extension arms for wall-mounted mirrors, temporary fences, pantographic knives, scissor lifts, and other scissor mechanisms such as the pantograph used on electric locomotives and trams.

Vacuums
A vacuum is a space devoid of matter. The word is derived from the Latin adjective ''vacuus'' for "vacant" or "void". An approximation to such vacuum is a region with a gaseous pressure much less than atmospheric pressure. Physicists often discuss ideal test results that would occur in a ''perfect'' vacuum, which they sometimes simply call "vacuum" or free space, and use the term partial vacuum to refer to an actual imperfect vacuum as one might have in a laboratory or in space. In engineering and applied physics on the other hand, vacuum refers to any space in which the pressure is considerably lower than atmospheric pressure. The Latin term ''in vacuo'' is used to describe an object that is surrounded by a vacuum. The ''quality'' of a partial vacuum refers to how closely it approaches a perfect vacuum. Other things equal, lower gas pressure means higher-quality vacuum. For example, a typical vacuum cleaner produces enough suction to reduce air pressure by around 20%. But high ...

Count Of Solms
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. . The etymologically related English term "county" denoted the territories associated with the countship. Definition The word ''count'' came into English from the French ''comte'', itself from Latin ''comes''—in its accusative ''comitem''—meaning “companion”, and later “companion of the emperor, delegate of the emperor”. The adjective form of the word is "comital". The British and Irish equivalent is an earl (whose wife is a "countess", for lack of an English term). In the late Roman Empire, the Latin title ''comes'' denoted the high rank of various courtiers and provincial officials, either military or administrative: before Anthemius became emperor in the West in 467, he was a military ''comes ...

Thirty Years' War
The Thirty Years' War was one of the longest and most destructive conflicts in European history, lasting from 1618 to 1648. Fought primarily in Central Europe, an estimated 4.5 to 8 million soldiers and civilians died as a result of battle, famine, and disease, while some areas of what is now modern Germany experienced population declines of over 50%. Related conflicts include the Eighty Years' War, the War of the Mantuan Succession, the Franco-Spanish War, and the Portuguese Restoration War. Until the 20th century, historians generally viewed it as a continuation of the religious struggle initiated by the 16th-century Reformation within the Holy Roman Empire. The 1555 Peace of Augsburg attempted to resolve this by dividing the Empire into Lutheran and Catholic states, but over the next 50 years the expansion of Protestantism beyond these boundaries destabilised the settlement.
