European science in the Middle Ages
European science in the Middle Ages comprised the study of nature and natural philosophy in medieval Europe. Following the fall of the Western Roman Empire and the decline in knowledge of Greek, Christian Western Europe was cut off from an important source of ancient learning. Although a range of Christian clerics and scholars from Isidore and Bede to Buridan and Oresme maintained the spirit of rational inquiry, Western Europe would see a period of scientific decline during the Early Middle Ages. However, by the time of the High Middle Ages, the region had rallied and was on its way to once more taking the lead in scientific discovery. Scholarship and scientific discoveries of the Late Middle Ages laid the groundwork for the Scientific Revolution of the Early Modern Period. According to Pierre Duhem, who founded the academic study of medieval science as a critique of the Enlightenment-positivist theory of a 17th-century anti-Aristotelian and anticlerical scientific revolution, the various conceptual origins of that alleged revolution lay in the 12th to 14th centuries, in the works of churchmen such as Aquinas and Buridan.
In the context of this article, "Western Europe" refers to the European cultures bound together by the Roman Catholic Church and the Latin language. As Roman imperial authority ended in the West during the 5th century, Western Europe entered the Middle Ages with great difficulties that affected the continent's intellectual production dramatically. Most classical scientific treatises of classical antiquity written in Greek were unavailable, leaving only simplified summaries and compilations. Nonetheless and early medieval scientific texts were read and studied, contributing to the understanding of nature as a coherent system functioning under divinely established laws that could be comprehended in the light of reason; this study continued through the Early Middle Ages, with the Renaissance of the 12th century, interest in this study was revitalized through the translation of Greek and Arabic scientific texts. Scientific study further developed within the emerging medieval universities, where these texts were studied and elaborated, leading to new insights into the phenomena of the universe.
These advances are unknown to the lay public of today because most theories advanced in medieval science are today obsolete, because of the caricature of Middle Ages as a "Dark Age" which placed "the word of religious authorities over personal experience and rational activity." In the ancient world, Greek had been the primary language of science. Under the Roman Empire, Latin texts drew extensively on Greek work, some pre-Roman, some contemporary. Late Roman attempts to translate Greek writings into Latin had limited success; as the knowledge of Greek declined during the transition to the Middle Ages, the Latin West found itself cut off from its Greek philosophical and scientific roots. Most scientific inquiry came to be based on information gleaned from sources which were incomplete and posed serious problems of interpretation. Latin-speakers who wanted to learn about science only had access to books by such Roman writers as Calcidius, Martianus Capella, Boethius and Latin encyclopedists. Much had to be gleaned from non-scientific sources: Roman surveying manuals were read for what geometry was included.
De-urbanization reduced the scope of education and by the 6th century teaching and learning moved to monastic and cathedral schools, with the center of education being the study of the Bible. Education of the laity survived modestly in Italy and the southern part of Gaul, where Roman influences were most long-lasting. In the 7th century, learning began to emerge in Ireland and the Celtic lands, where Latin was a foreign language and Latin texts were eagerly studied and taught; the leading scholars of the early centuries were clergymen for whom the study of nature was but a small part of their interest. They lived in an atmosphere which provided little institutional support for the disinterested study of natural phenomena; the study of nature was pursued more for practical reasons than as an abstract inquiry: the need to care for the sick led to the study of medicine and of ancient texts on drugs, the need for monks to determine the proper time to pray led them to study the motion of the stars, the need to compute the date of Easter led them to study and teach rudimentary mathematics and the motions of the Sun and Moon.
Modern readers may find it disconcerting that sometimes the same works discuss both the technical details of natural phenomena and their symbolic significance. Around 800, Charles the Great, assisted by the English monk Alcuin of York, undertook what has become known as the Carolingian Renaissance, a program of cultural revitalization and educational reform; the chief scientific aspect of Charlemagne's educational reform concerned the study and teaching of astronomy, both as a practical art that clerics required to compute the date of Easter and as a theoretical discipline. From the year 787 on, decrees were issued recommending the restoration of old schools and the founding of new ones throughout the empire. Institutionally, these new schools were either under the responsibility of a monastery, a cathedral or a noble court; the scientific work of the period after Charlemagne was not so much concerned with original investigation as it was with the active study and investigation of ancient Roman scientific texts.
This investigation paved the way for the effort of Western scholars to recover and translate ancient Greek texts in philosophy and the sciences. Beginning around the year 1050, European scholars built
Physics is the natural science that studies matter, its motion, behavior through space and time, that studies the related entities of energy and force. Physics is one of the most fundamental scientific disciplines, its main goal is to understand how the universe behaves. Physics is one of the oldest academic disciplines and, through its inclusion of astronomy the oldest. Over much of the past two millennia, chemistry and certain branches of mathematics, were a part of natural philosophy, but during the scientific revolution in the 17th century these natural sciences emerged as unique research endeavors in their own right. Physics intersects with many interdisciplinary areas of research, such as biophysics and quantum chemistry, the boundaries of physics which are not rigidly defined. New ideas in physics explain the fundamental mechanisms studied by other sciences and suggest new avenues of research in academic disciplines such as mathematics and philosophy. Advances in physics enable advances in new technologies.
For example, advances in the understanding of electromagnetism and nuclear physics led directly to the development of new products that have transformed modern-day society, such as television, domestic appliances, nuclear weapons. Astronomy is one of the oldest natural sciences. Early civilizations dating back to beyond 3000 BCE, such as the Sumerians, ancient Egyptians, the Indus Valley Civilization, had a predictive knowledge and a basic understanding of the motions of the Sun and stars; the stars and planets were worshipped, believed to represent gods. While the explanations for the observed positions of the stars were unscientific and lacking in evidence, these early observations laid the foundation for astronomy, as the stars were found to traverse great circles across the sky, which however did not explain the positions of the planets. According to Asger Aaboe, the origins of Western astronomy can be found in Mesopotamia, all Western efforts in the exact sciences are descended from late Babylonian astronomy.
Egyptian astronomers left monuments showing knowledge of the constellations and the motions of the celestial bodies, while Greek poet Homer wrote of various celestial objects in his Iliad and Odyssey. Natural philosophy has its origins in Greece during the Archaic period, when pre-Socratic philosophers like Thales rejected non-naturalistic explanations for natural phenomena and proclaimed that every event had a natural cause, they proposed ideas verified by reason and observation, many of their hypotheses proved successful in experiment. The Western Roman Empire fell in the fifth century, this resulted in a decline in intellectual pursuits in the western part of Europe. By contrast, the Eastern Roman Empire resisted the attacks from the barbarians, continued to advance various fields of learning, including physics. In the sixth century Isidore of Miletus created an important compilation of Archimedes' works that are copied in the Archimedes Palimpsest. In sixth century Europe John Philoponus, a Byzantine scholar, questioned Aristotle's teaching of physics and noting its flaws.
He introduced the theory of impetus. Aristotle's physics was not scrutinized until John Philoponus appeared, unlike Aristotle who based his physics on verbal argument, Philoponus relied on observation. On Aristotle's physics John Philoponus wrote: “But this is erroneous, our view may be corroborated by actual observation more than by any sort of verbal argument. For if you let fall from the same height two weights of which one is many times as heavy as the other, you will see that the ratio of the times required for the motion does not depend on the ratio of the weights, but that the difference in time is a small one, and so, if the difference in the weights is not considerable, that is, of one is, let us say, double the other, there will be no difference, or else an imperceptible difference, in time, though the difference in weight is by no means negligible, with one body weighing twice as much as the other”John Philoponus' criticism of Aristotelian principles of physics served as an inspiration for Galileo Galilei ten centuries during the Scientific Revolution.
Galileo cited Philoponus in his works when arguing that Aristotelian physics was flawed. In the 1300s Jean Buridan, a teacher in the faculty of arts at the University of Paris, developed the concept of impetus, it was a step toward the modern ideas of momentum. Islamic scholarship inherited Aristotelian physics from the Greeks and during the Islamic Golden Age developed it further placing emphasis on observation and a priori reasoning, developing early forms of the scientific method; the most notable innovations were in the field of optics and vision, which came from the works of many scientists like Ibn Sahl, Al-Kindi, Ibn al-Haytham, Al-Farisi and Avicenna. The most notable work was The Book of Optics, written by Ibn al-Haytham, in which he conclusively disproved the ancient Greek idea about vision, but came up with a new theory. In the book, he presented a study of the phenomenon of the camera obscura (his thousand-year-old
Babylonia was an ancient Akkadian-speaking state and cultural area based in central-southern Mesopotamia. A small Amorite-ruled state emerged in 1894 BC, which contained the minor administrative town of Babylon, it was a small provincial town during the Akkadian Empire but expanded during the reign of Hammurabi in the first half of the 18th century BC and became a major capital city. During the reign of Hammurabi and afterwards, Babylonia was called "the country of Akkad", a deliberate archaism in reference to the previous glory of the Akkadian Empire, it was involved in rivalry with the older state of Assyria to the north and Elam to the east in Ancient Iran. Babylonia became the major power in the region after Hammurabi created a short-lived empire, succeeding the earlier Akkadian Empire, Third Dynasty of Ur, Old Assyrian Empire; the Babylonian Empire, however fell apart after the death of Hammurabi and reverted to a small kingdom. Like Assyria, the Babylonian state retained the written Akkadian language for official use, despite its Northwest Semitic-speaking Amorite founders and Kassite successors, who spoke a language isolate, not being native Mesopotamians.
It retained the Sumerian language for religious use, but by the time Babylon was founded, this was no longer a spoken language, having been wholly subsumed by Akkadian. The earlier Akkadian and Sumerian traditions played a major role in Babylonian and Assyrian culture, the region would remain an important cultural center under its protracted periods of outside rule; the earliest mention of the city of Babylon can be found in a clay tablet from the reign of Sargon of Akkad, dating back to the 23rd century BC. Babylon was a religious and cultural centre at this point and neither an independent state nor a large city. After the collapse of the Akkadian Empire, the south Mesopotamian region was dominated by the Gutian people for a few decades before the rise of the Third Dynasty of Ur, which restored order to the region and which, apart from northern Assyria, encompassed the whole of Mesopotamia, including the town of Babylon. Mesopotamia had enjoyed a long history prior to the emergence of Babylon, with Sumerian civilisation emerging in the region c. 3500 BC, the Akkadian-speaking people appearing by the 30th century BC.
During the 3rd millennium BC, an intimate cultural symbiosis occurred between Sumerian and Akkadian-speakers, which included widespread bilingualism. The influence of Sumerian on Akkadian and vice versa is evident in all areas, from lexical borrowing on a massive scale, to syntactic and phonological convergence; this has prompted scholars to refer to Sumerian and Akkadian in the third millennium as a sprachbund. Akkadian replaced Sumerian as the spoken language of Mesopotamia somewhere around the turn of the third and the second millennium BC. From c. 3500 BC until the rise of the Akkadian Empire in the 24th century BC, Mesopotamia had been dominated by Sumerian cities and city states, such as Ur, Uruk, Isin, Adab, Gasur, Hamazi, Akshak and Umma, although Semitic Akkadian names began to appear on the king lists of some of these states between the 29th and 25th centuries BC. Traditionally, the major religious center of all Mesopotamia was the city of Nippur where the god Enlil was supreme, it would remain so until replaced by Babylon during the reign of Hammurabi in the mid-18th century BC.
The Akkadian Empire saw the Akkadian Semites and Sumerians of Mesopotamia unite under one rule, the Akkadians attain ascendancy over the Sumerians and indeed come to dominate much of the ancient Near East. The empire disintegrated due to economic decline, climate change and civil war, followed by attacks by the Gutians from the Zagros Mountains. Sumer rose up again with the Third Dynasty of Ur in the late 22nd century BC, ejected the Gutians from southern Mesopotamia, they seem to have gained ascendancy over much of the territory of the Akkadian kings of Assyria in northern Mesopotamia for a time. Followed by the collapse of the Sumerian "Ur-III" dynasty at the hands of the Elamites in 2002 BC, the Amorites, a foreign Northwest Semitic-speaking people, began to migrate into southern Mesopotamia from the northern Levant gaining control over most of southern Mesopotamia, where they formed a series of small kingdoms, while the Assyrians reasserted their independence in the north; the states of the south were unable to stem the Amorite advance, for a time may have relied on their fellow Akkadians in Assyria for protection.
King Ilu-shuma of the Old Assyrian Empire in a known inscription describes his exploits to the south as follows: The freedom of the Akkadians and their children I established. I purified their copper. I established their freedom from the border of the marshes and Ur and Nippur and Kish, Der of the goddess Ishtar, as far as the City of. Past scholars extrapolated from this text that it means he defeated the invading Amorites to the south and Elamites to the east, but there is no explicit record of that, some scholars believe the Assyrian kings were giving preferential trade agreements to the south; these policies were continued by Ikunum. However, when Sargon I s
Ludwig Maximilian University of Munich
Ludwig Maximilian University of Munich is a public research university located in Munich, Germany. The University of Munich is Germany's sixth-oldest university in continuous operation. Established in Ingolstadt in 1472 by Duke Ludwig IX of Bavaria-Landshut, the university was moved in 1800 to Landshut by King Maximilian I of Bavaria when Ingolstadt was threatened by the French, before being relocated to its present-day location in Munich in 1826 by King Ludwig I of Bavaria. In 1802, the university was named Ludwig-Maximilians-Universität by King Maximilian I of Bavaria in his as well as the university's original founder's honour; the University of Munich has since the 19th century, been considered as one of Germany's as well as one of Europe's most prestigious universities. Among these were Wilhelm Röntgen, Max Planck, Werner Heisenberg, Otto Hahn and Thomas Mann. Pope Benedict XVI was a student and professor at the university; the LMU has been conferred the title of "elite university" under the German Universities Excellence Initiative.
LMU is the second-largest university in Germany in terms of student population. Of these, 8,671 were freshmen while international students totalled 7,812 or 15% of the student population; as for operating budget, the university records in 2015 a total of 660.0 million euros in funding without the university hospital. The University was founded with papal approval in 1472 as the University of Ingolstadt, with faculties of philosophy, medicine and theology, its first rector was Christopher Mendel of Steinfels, who became bishop of Chiemsee. In the period of German humanism, the university's academics included names such as Conrad Celtes and Petrus Apianus; the theologian Johann Eck taught at the university. From 1549 to 1773, the university was influenced by the Jesuits and became one of the centres of the Counter-Reformation; the Jesuit Petrus Canisius served as rector of the university. At the end of the 18th century, the university was influenced by the Enlightenment, which led to a stronger emphasis on natural science.
In 1800, the Prince-Elector Maximilian IV Joseph moved the university to Landshut, due to French aggression that threatened Ingolstadt during the Napoleonic Wars. In 1802, the university was renamed the Ludwig Maximilian University in honour of its two founders, Louis IX, Duke of Bavaria and Maximilian I, Elector of Bavaria; the Minister of Education, Maximilian von Montgelas, initiated a number of reforms that sought to modernize the rather conservative and Jesuit-influenced university. In 1826, it was moved to the capital of the Kingdom of Bavaria; the university was situated in the Old Academy until a new building in the Ludwigstraße was completed. The locals were somewhat critical of the number of Protestant professors Maximilian and Ludwig I invited to Munich, they were dubbed the "Nordlichter" and physician Johann Nepomuk von Ringseis was quite angry about them. In the second half of the 19th century, the university rose to great prominence in the European scientific community, attracting many of the world's leading scientists.
It was a period of great expansion. From 1903, women were allowed to study at Bavarian universities, by 1918, the female proportion of students at LMU had reached 18%. In 1918, Adele Hartmann became the first woman in Germany to earn the Habilitation, at LMU. During the Weimar Republic, the university continued to be one of the world's leading universities, with professors such as Wilhelm Röntgen, Wilhelm Wien, Richard Willstätter, Arnold Sommerfeld and Ferdinand Sauerbruch. During the Third Reich, academic freedom was curtailed. In 1943 the White Rose group of anti-Nazi students conducted their campaign of opposition to the National Socialists at this university; the university has continued to be one of the leading universities of West Germany during the Cold War and in the post-reunification era. In the late 1960s, the university was the scene of protests by radical students. Today the University of Munich is part of 24 Collaborative Research Centers funded by the German Research Foundation and is host university of 13 of them.
It hosts 12 DFG Research Training Groups and three international doctorate programs as part of the Elite Network of Bavaria. It attracts an additional 120 million euros per year in outside funding and is intensively involved in national and international funding initiatives. LMU Munich has a wide range of degree programs, with 150 subjects available in numerous combinations. 15% of the 45,000 students who attend the university come from abroad. In 2005, Germany’s state and federal governments launched the German Universities Excellence Initiative, a contest among its universities. With a total of 1.9 billion euros, 75 percent of which comes from the federal state, its architects aim to strategically promote top-level research and scholarship. The money is given to more than 30 research universities in Germany; the initiative will fund three project-oriented areas: graduate schools to promote the next generation of scholars, clusters of excellence to promote cutting-edge research and "future concepts" for the project-based expansion of academic excellence at universities as a whole.

National Academy of Sciences
The National Academy of Sciences is a United States nonprofit, non-governmental organization. NAS is part of the National Academies of Sciences and Medicine, along with the National Academy of Engineering and the National Academy of Medicine; as a national academy, new members of the organization are elected annually by current members, based on their distinguished and continuing achievements in original research. Election to the National Academy is one of the highest honors in the scientific field. Members serve pro bono as "advisers to the nation" on science and medicine; the group holds a congressional charter under Title 36 of the United States Code. Founded in 1863 as a result of an Act of Congress, approved by Abraham Lincoln, the NAS is charged with "providing independent, objective advice to the nation on matters related to science and technology. … to provide scientific advice to the government'whenever called upon' by any government department. The Academy receives no compensation from the government for its services."
As of 2016, the National Academy of Sciences includes about 2,350 members and 450 foreign associates. It employed about 1,100 staff in 2005; the current members annually elect new members for life. Up to 84 members who are US citizens are elected every year. 190 members have won a Nobel Prize. By its own admission in 1989, the addition of women to the Academy "continues at a dismal trickle", at which time there were 1,516 male members and 57 female members; the National Academy of Sciences is a member of the International Council for Science. The ICSU Advisory Committee, in the Research Council's Office of International Affairs, facilitates participation of members in international scientific unions and serves as a liaison for U. S. national committees for individual scientific unions. Although there is no formal relationship with state and local academies of science, there is informal dialogue; the National Academy is governed by a 17-member Council, made up of five officers and 12 Councilors, all of whom are elected from among the Academy membership.
About 85 percent of funding comes from the federal government through contracts and grants from agencies and 15 percent from state governments, private foundations, industrial organizations, funds provided by the Academies member organizations. The Council has the ability ad-hoc to delegate certain tasks to committees. For example, the Committee on Animal Nutrition has produced a series of Nutrient requirements of domestic animals reports since at least 1944, each one being initiated by a different sub-committee of experts in the field for example on dairy cattle; the National Academy of Sciences meets annually in Washington, D. C., documented in the Proceedings of the National Academy of Sciences, its scholarly journal. The National Academies Press is the publisher for the National Academies, makes more than 5,000 publications available on its website. From 2004 to 2017, the National Academy of Sciences administered the Marian Koshland Science Museum to provide public exhibits and programming related to its policy work.
The museum's exhibits focused on infectious disease. In 2017 the museum closed and made way for a new science outreach program called LabX; the National Academy of Sciences maintains multiple buildings around the United States. The National Academy of Sciences Building is located at 2101 Constitution Avenue, in northwest Washington, D. C.. S. State Department; the building has a neoclassical architectural style and was built by architect Bertram Grosvenor Goodhue. The building is listed on the National Register of Historic Places. Goodhue engaged a team of artists and architectural sculptors including Albert Herter, Lee Lawrie, Hildreth Meiere to design interior embellishments celebrating the history and significance of science; the building is used for lectures, symposia and concerts, in addition to annual meetings of the NAS, NAE, NAM. The 2012 Presidential Award for Math and Science Teaching ceremony was held here on March 5, 2014. 150 staff members work at the NAS Building. In June 2012, it reopened to visitors after a major two-year restoration project which restored and improved the building's historic spaces, increased accessibility, brought the building's aging infrastructure and facilities up to date.
More than 1,000 National Academies staff members work at The Keck Center of the National Academies at 500 Fifth Street in northwest Washington, D. C; the Keck Center houses the National Academies Press Bookstore. The Marian Koshland Science Museum of the National Academy of Sciences – located at 525 E St. N. W. – hosted visits from the public, school field trips, traveling exhibits, permanent science exhibits. The NAS maintains conference centers in California and Massachusetts; the Arnold and Mabel Beckman Center is located on 100 Academy Drive in Irvine, near the campus of the University of California, Irvine. The J. Erik Jonsson Conference Center located at 314 Quissett Avenue in Woods Hole, Massachusetts, is another conference facility; the Act of Incorporation, signed by President Abraham Lincoln on March 3, 1863, created the National Academy of Sciences and named 50 charter members. Many of the original NAS members came from the so-called "Scientific Lazzaroni," an informal network of phy
