Erhard Weigel
Erhard Weigel (16 December 1625 – 20 March 1699) was a German mathematician, astronomer and philosopher. Biography Weigel earned his M.A. (1650) and his habilitation (1652) from the University of Leipzig. From 1653 until his death he was professor of mathematics at Jena University. He was the teacher of Leibniz in summer 1663,Richard T. W. Arthur, 2014. ''Leibniz''. John Wiley & Sons. p. 16. and other notable students. He also worked to make science more widely accessible to the public, and what would today be considered a populariser of science. He concurred with Jakob Ellrod's "Mittel-Calendar", and with the advocacy of Leibniz and others, that the date of Easter should be based on the astronomical measurement of the spring equinox and the next full moon. He followed Jakob Ellrod to the Imperial Diet in Regensburg to advocate the use of the Mittel-Calendar or New Gregorian calendar.

Jena University
The University of Jena, officially the Friedrich Schiller University Jena (german: Friedrich-Schiller-Universität Jena, abbreviated FSU, shortened form ''Uni Jena''), is a public research university located in Jena, Thuringia, Germany. The university was established in 1558 and is counted among the ten oldest universities in Germany. It is affiliated with six Nobel Prize winners, most recently in 2000 when Jena graduate Herbert Kroemer won the Nobel Prize for physics. In the 2023 Times Higher Education World University Rankings, the university was awarded 189th place in the world. It was renamed after the poet Friedrich Schiller who was teaching as professor of philosophy when Jena attracted some of the most influential minds at the turn of the 19th century. With Karl Leonhard Reinhold, Johann Gottlieb Fichte, G. W. F. Hegel, F. W. J. Schelling and Friedrich Schlegel on its teaching staff, the university was at the centre of the emergence of German idealism and early Romant ...

Mathematics Genealogy Project
The Mathematics Genealogy Project (MGP) is a web-based database for the academic genealogy of mathematicians.. By 31 December 2021, it contained information on 274,575 mathematical scientists who contributed to research-level mathematics. For a typical mathematician, the project entry includes graduation year, thesis title (in its Mathematics Subject Classification), '' alma mater'', doctoral advisor, and doctoral students.. Origin of the database The project grew out of founder Harry Coonce's desire to know the name of his advisor's advisor.. Coonce was Professor of Mathematics at Minnesota State University, Mankato, at the time of the project's founding, and the project went online there in fall 1997.Mulcahy, Colm;The Mathematics Genealogy Project Comes of Age at Twenty-one(PDF) AMS Notices (May 2017) Coonce retired from Mankato in 1999, and in fall 2002 the university decided that it would no longer support the project.

Christiaan Huygens
Christiaan Huygens, Lord of Zeelhem, ( , , ; also spelled Huyghens; la, Hugenius; 14 April 1629 – 8 July 1695) was a Dutch mathematician, physicist, engineer, astronomer, and inventor, who is regarded as one of the greatest scientists of all time and a major figure in the Scientific Revolution. In physics, Huygens made groundbreaking contributions in optics and mechanics, while as an astronomer he is chiefly known for his studies of the rings of Saturn and the discovery of its moon Titan. As an engineer and inventor, he improved the design of telescopes and invented the pendulum clock, a breakthrough in timekeeping and the most accurate timekeeper for almost 300 years. An exceptionally talented mathematician and physicist, Huygens was the first to idealize a physical problem by a set of mathematical parameters, and the first to fully mathematize a mechanistic explanation of an unobservable physical phenomenon.Dijksterhuis, F.J.

Halle (Saale), or simply Halle (; from the 15th to the 17th century: ''Hall in Sachsen''; until the beginning of the 20th century: ''Halle an der Saale'' ; from 1965 to 1995: ''Halle/Saale'') is the largest city of the German state of Saxony-Anhalt, the fifth most populous city in the area of former East Germany after (East) Berlin, Leipzig, Dresden and Chemnitz, as well as the 31st largest city of Germany, and with around 239,000 inhabitants, it is slightly more populous than the state capital of Magdeburg.

Ansbach-Bayreuth
The Principality or Margraviate of (Brandenburg-)Ansbach (german: Fürstentum Ansbach or ) was a principality in the Holy Roman Empire centered on the Franconian city of Ansbach. The ruling Hohenzollern princes of the land were known as margraves, as their ancestors were margraves (so the principality was a margraviate but not a march). History The principality was established at the death of Frederick V, Burgrave of Nuremberg, on 21 January 1398, when his lands were partitioned between his two sons. The younger son, Frederick VI, received Ansbach and the elder, John III, received Bayreuth. After John III's death on 11 June 1420, the two principalities were reunited under Frederick VI, who had become Elector Frederick I of Brandenburg in 1415. Upon Frederick I's death on 21 September 1440, his territories were divided between his sons; John received the principality of Bayreuth (Brandenburg-Kulmbach), Frederick received Brandenburg, and Albert received Ansbach.

Gregorian Calendar
The Gregorian calendar is the calendar used in most parts of the world. It was introduced in October 1582 by Pope Gregory XIII as a modification of, and replacement for, the Julian calendar. The principal change was to space leap years differently so as to make the average calendar year 365.2425 days long, more closely approximating the 365.2422-day 'tropical' or 'solar' year that is determined by the Earth's revolution around the Sun. The rule for leap years is: There were two reasons to establish the Gregorian calendar. First, the Julian calendar assumed incorrectly that the average solar year is exactly 365.25 days long, an overestimate of a little under one day per century, and thus has a leap year every four years without exception. The Gregorian reform shortened the average (calendar) year by 0.0075 days to stop the drift of the calendar with respect to the equinoxes.See Wikisource English translation of the (Latin) 1582 papal bull '' Inter gravissimas''.

Regensburg
Regensburg or is a city in eastern Bavaria, at the confluence of the Danube, Naab and Regen rivers. It is capital of the Upper Palatinate subregion of the state in the south of Germany. With more than 150,000 inhabitants, Regensburg is the fourth-largest city in the State of Bavaria after Munich, Nuremberg and Augsburg. From its foundation as an imperial Roman river fort, the city has been the political, economic and cultural centre of the surrounding region; it is still known in the Romance languages by a cognate of its Latin name of "Ratisbona" (the version "Ratisbon" was long current in English). Later, under the rule of the Holy Roman Empire, it housed the Perpetual Diet of Regensburg. The medieval centre of the city was made a UNESCO World Heritage Site in 2006 because of its well-preserved architecture and the city's historical importance for assemblies during the Holy Roman Empire. In 2014, Regensburg was among the top sights and travel attractions in Germany. Histor ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Imperial Diet (Holy Roman Empire)
The Imperial Diet ( la, Dieta Imperii Comitium Imperiale; german: Reichstag) was the deliberative body of the Holy Roman Empire. It was not a legislative body in the contemporary sense; its members envisioned it more like a central forum where it was more important to negotiate than to decide. Its members were the Imperial Estates, divided into three colleges. The diet as a permanent, regularized institution evolved from the ''Hoftage'' (court assemblies) of the Middle Ages. From 1663 until the end of the empire in 1806, it was in permanent session at Regensburg. All Imperial Estates enjoyed immediacy and, therefore, they had no authority above them besides the Holy Roman Emperor himself. While all the estates were entitled to a seat and vote, only the higher temporal and spiritual princes of the College of Princes enjoyed an individual vote (''Virilstimme''), while lesser estates such as imperial counts and imperial abbots, were merely entitled to a collective vote (''Kuriats ...
