Petrus Astronomus
Petrus Astronomus, O.Ss.S., (died after 1513), a German by birth, was a Bridgettine monk in Vadstena Abbey, Vadstena, Sweden. In 1506, he created an astronomical clock for the Uppsala Cathedral, which, in addition to the hours and minutes of the day, also illustrated the moon phase and the movements of the planets. The clock was repaired by Christopher Polhem in the 17th century but destroyed in a fire in 1702. He first appears by name as a lecturer in astronomy at Uppsala University, where between 1508 and 1509 he conducted a series of lectures. He is sometimes erroneously confused for Conrad Dasypodius Conrad Dasypodius (1532 – 26 April 1600) was a Swiss astronomer, mathematician, and writer. He was a professor of mathematics in Strasbourg, Alsace. He was born in Frauenfeld, Thurgau, Switzerland.

Astronomical Clock
An astronomical clock, horologium, or orloj is a clock with special mechanisms and dials to display astronomical information, such as the relative positions of the Sun, Moon, zodiacal constellations, and sometimes major planets. Definition The term is loosely used to refer to any clock that shows, in addition to the time of day, astronomical information. This could include the location of the Sun and Moon in the sky, the age and Lunar phases, the position of the Sun on the ecliptic and the current zodiac sign, the sidereal time, and other astronomical data such as the Moon's nodes for indicating eclipses), or a rotating star map. The term should not be confused with an ''astronomical regulator'', a high precision but otherwise ordinary pendulum clock used in observatories. Astronomical clocks usually represent the Solar System using the geocentric model. The center of the dial is often marked with a disc or sphere representing the Earth, located at the center of the S ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Medieval
In the history of Europe, the Middle Ages or medieval period lasted approximately from the 5th to the late 15th centuries, similarly to the post-classical period of World history (field), global history. It began with the fall of the Western Roman Empire and transitioned into the Renaissance and the Age of Discovery. The Middle Ages is the middle period of the three traditional divisions of Western history: classical antiquity, the medieval period, and the modern period. The medieval period is itself subdivided into the Early Middle Ages, Early, High Middle Ages, High, and Late Middle Ages. Population decline, counterurbanisation, the collapse of centralised authority, invasions, and mass migrations of tribes, which had begun in late antiquity, continued into the Early Middle Ages. The large-scale movements of the Migration Period, including various Germanic peoples, formed new kingdoms in what remained of the Western Roman Empire. In the 7th century, North Africa and the ...

Autobiography
An autobiography, sometimes informally called an autobio, is a self-written account of one's own life, providing a personal narrative that reflects on the author's experiences, memories, and insights. This genre allows individuals to share their unique perspectives and stories, offering readers a glimpse into the author's personal journey and the historical or cultural context in which they lived. The term "autobiography" was first used in 1797, but the practice of writing about one's life dates back to antiquity. Early examples include Saint Augustine's '' Confessions'' (), which is considered one of the first Western autobiographies. Unlike biographies, which are written by someone else, autobiographies are based on the author's memory and personal interpretation of events, making them inherently subjective. This subjectivity can sometimes lead to inaccuracies or embellishments, as the author may recall events differently or choose to present them in a certain light. Autobi ...

Anders Celsius
Anders Celsius (; 27 November 170125 April 1744) was a Swedes, Swedish astronomer, physicist and mathematician. He was professor of astronomy at Uppsala University from 1730 to 1744, but traveled from 1732 to 1735 visiting notable observatories in Germany, Italy and France. He founded the Uppsala Astronomical Observatory in 1741, and in 1742 proposed (an inverted form of) the Celsius, Centigrade temperature scale which was later renamed Celsius in his honour. Early life and education Anders Celsius was born in Uppsala, Sweden, on 27 November 1701. His family originated from Ovanåker in the province of Hälsingland. Their family estate was at ''Doma'', also known as ''Höjen'' or ''Högen'' (locally as ''Högen 2''). The name ''Celsius'' is a latinization of the estate's name (Latin 'mound'). As the son of an astronomy professor, Nils Celsius, nephew of botanist Olof Celsius and the grandson of the mathematician Magnus Celsius and the astronomer Anders Spole, Celsius chose a ca ...

Södertörn
Södertörn is a roughly triangular peninsula and artificial island in eastern Södermanland, Sweden, with an area of 1,207 km² and is bordered by: *Lake Mälaren, the Hammarby Canal and the inlet of Saltsjön (a part of the Baltic Sea) to the north, *The Baltic Sea (the Stockholm Archipelago) to the east and the south, * Himmerfjärden and Hallsfjärden (parts of the Baltic Sea) to the west as well as *The Södertälje Canal to the northwest. The Södertälje Canal and Hammarby Canal are man-made waterways, so the peninsula of Södertörn is not fully separated from (the rest of) the Swedish mainland or the island of Södermalm by nature, although Södertörn is classified as an island by Statistics Sweden, and the third largest island in Sweden. Since 2005, the whole of Södertörn has been included in Metropolitan Stockholm. Before that, the southern parts of the island, which lie within Nynäshamn Municipality, and the western parts, which are in Södertälje Muni ...
