Middle Ages
In European history, the Middle Ages or medieval period lasted from the 5th to the 15th century. It began with the collapse of the Western Roman Empire and merged into the Renaissance and the Age of Discovery. The Middle Ages is the middle period of the three traditional divisions of Western history: Antiquity, Medieval period, and Modern period. The Medieval period is itself subdivided into the Early, the High, and the Late Middle Ages.

History of science
Political science is a late arrival in terms of social sciences[citation needed]. However, the discipline has a clear set of antecedents such as moral philosophy, political philosophy, political economy, history, and other fields concerned with normative determinations of what ought to be and with deducing the characteristics and functions of the ideal form of government. The roots of politics are in prehistory. In each historic period and in almost every geographic area, we can find someone studying politics and increasing political understanding.
Race (human categorization)
Morning (2008) looked at high school biology textbooks during the 1952-2002 period and initially found a similar pattern with only 35% directly discussing race in the 1983–92 period from initially 92% doing so. However, this has increased somewhat after this to 43%. More indirect and brief discussions of race in the context of medical disorders have increased from none to 93% of textbooks. In general, the material on race has moved from surface traits to genetics and evolutionary history. The study argues that the textbooks' fundamental message about the existence of races has changed little.
Glacier
Mean speeds vary greatly, but is typically around 1 m (3 ft) per day. There may be no motion in stagnant areas; for example, in parts of Alaska, trees can establish themselves on surface sediment deposits. In other cases, glaciers can move as fast as 20–30 m (70–100 ft) per day, such as in Greenland's Jakobshavn Isbræ (Greenlandic: Sermeq Kujalleq). Velocity increases with increasing slope, increasing thickness, increasing snowfall, increasing longitudinal confinement, increasing basal temperature, increasing meltwater production and reduced bed hardness.
Brain
Most of the space in the brain is taken up by axons, which are often bundled together in what are called nerve fiber tracts. A myelinated axon is wrapped in a fatty insulating sheath of myelin, which serves to greatly increase the speed of signal propagation. (There are also unmyelinated axons). Myelin is white, making parts of the brain filled exclusively with nerve fibers appear as light-colored white matter, in contrast to the darker-colored grey matter that marks areas with high densities of neuron cell bodies.
Geological history of Earth
The Ordovician Period started at a major extinction event called the Cambrian-Ordovician extinction events some time about 485.4 ± 1.9 Ma. During the Ordovician the southern continents were collected into a single continent called Gondwana. Gondwana started the period in the equatorial latitudes and, as the period progressed, drifted toward the South Pole. Early in the Ordovician the continents Laurentia, Siberia and Baltica were still independent continents (since the break-up of the supercontinent Pannotia earlier), but Baltica began to move toward Laurentia later in the period, causing the Iapetus Ocean to shrink between them. Also, Avalonia broke free from Gondwana and began to head north toward Laurentia. The Rheic Ocean was formed as a result of this. By the end of the period, Gondwana had neared or approached the pole and was largely glaciated.
History of Australia
A First Fleet of British ships arrived at Botany Bay in January 1788 to establish a penal colony, the first colony on the Australian mainland. In the century that followed, the British established other colonies on the continent, and European explorers ventured into its interior. Indigenous Australians were greatly weakened and their numbers diminished by introduced diseases and conflict with the colonists during this period.
Thurian Age
The Thurian Age is a specific epoch in the fictional timeline used by Robert E. Howard in his Kull stories. It predates the Hyborian Age of the Conan the Barbarian stories and is known to them as the "Pre-Cataclysmic Age". The main continent is called Thuria, although smaller continents such as Atlantis and an unnamed eastern continent exist, as do several island chains. Most of the world is unexplored wilderness inhabited by "scattered clans and tribes of primitive savages." The boundary between the two ages is marked by the "Great Cataclysm," which might have taken place as early as ca. 35,000 to 40,000 B.C, or as recently as 18,000 B.C. depending on the sources considered. When Robert E. Howard began to chronicle the adventures of Conan the Cimmerian, in the early 1930s, he prepared a fictional history of the Hyborian Age which he had created. That "history" dealt not only with the period during and after Conan's life, but also with events some eight thousand years earlier, during the Thurian civilization which produced King Kull, an exiled warrior from Atlantis, in the days before his continent sank into the surging seas.

Brain
The Roman physician Galen also argued for the importance of the brain, and theorized in some depth about how it might work. Galen traced out the anatomical relationships among brain, nerves, and muscles, demonstrating that all muscles in the body are connected to the brain through a branching network of nerves. He postulated that nerves activate muscles mechanically by carrying a mysterious substance he called pneumata psychikon, usually translated as "animal spirits". Galen's ideas were widely known during the Middle Ages, but not much further progress came until the Renaissance, when detailed anatomical study resumed, combined with the theoretical speculations of René Descartes and those who followed him. Descartes, like Galen, thought of the nervous system in hydraulic terms. He believed that the highest cognitive functions are carried out by a non-physical res cogitans, but that the majority of behaviors of humans, and all behaviors of animals, could be explained mechanistically.
Renaissance
The Renaissance (UK: / rɪˈneɪsəns /, US: / rɛnəˈsɑːns /) is a period in European history, covering the span between the 14th and 17th centuries. It is an extension of the Middle Ages, and is bridged by the Age of Enlightenment to modern history. It grew in fragments, with the very first traces found seemingly in Italy, coming to cover much of Europe, for some scholars marking the beginning of the modern age.
Autonomic nervous system
The autonomic nervous system is divided into the sympathetic nervous system and parasympathetic nervous system. The sympathetic division emerges from the spinal cord in the thoracic and lumbar areas, terminating around L2 - 3. The parasympathetic division has craniosacral ``outflow '', meaning that the neurons begin at the cranial nerves (specifically the oculomotor nerve, facial nerve, glossopharyngeal nerve and vagus nerve) and sacral (S2 - S4) spinal cord.
Mesozoic
Sea levels began to rise during the Jurassic, which was probably caused by an increase in seafloor spreading. The formation of new crust beneath the surface displaced ocean waters by as much as 200 m (656 ft) more than today, which flooded coastal areas. Furthermore, Pangaea began to rift into smaller divisions, bringing more land area in contact with the ocean by forming the Tethys Sea. Temperatures continued to increase and began to stabilize. Humidity also increased with the proximity of water, and deserts retreated.
Journal of Near Eastern Studies
The "Journal of Near Eastern Studies" is an academic journal published by the University of Chicago Press, covering research on the ancient and medieval civilisations of the Near East, including their archaeology, art, history, literature, linguistics, religion, law, and science. JNES is devoted to the study of the civilizations of the Near East from prehistory to the end of the Ottoman period in 1922. "JNES" embraces a uniquely broad scope of time, place, and topic, including contributions from scholars of international reputation on topics in Assyriology, Egyptology, Hittitology, Hebrew Bible, and allied ancient studies, as well as a second area of emphasis in early, medieval, and early-modern Islamic studies. The disciplinary range of the journal runs from history and language to religion and literature to archaeology and art history.
Daylight saving time
DST's potential to save energy comes primarily from its effects on residential lighting, which consumes about 3.5% of electricity in the United States and Canada. Delaying the nominal time of sunset and sunrise reduces the use of artificial light in the evening and increases it in the morning. As Franklin's 1784 satire pointed out, lighting costs are reduced if the evening reduction outweighs the morning increase, as in high-latitude summer when most people wake up well after sunrise. An early goal of DST was to reduce evening usage of incandescent lighting, which used to be a primary use of electricity. Although energy conservation remains an important goal, energy usage patterns have greatly changed since then, and recent research is limited and reports contradictory results. Electricity use is greatly affected by geography, climate, and economics, making it hard to generalize from single studies.
European migrant crisis
The European migrant crisis, or the European refugee crisis, is a term given to a period beginning in 2015 when rising numbers of people arrived in the European Union (EU), travelling across the Mediterranean Sea or overland through Southeast Europe. It is part of a pattern of increased immigration to Europe from other continents which began in the late 20th century and which has encountered resistance in many European countries.
John Hare (bishop)
He was educated at Brighton College and Corpus Christi College, Oxford. After a period of study at Ripon College Cuddesdon he was ordained in 1937 and began his career with a curacy at "St Francis of Assisi, West Bromwich " followed by a period as Vicar of "St Matthias, Colindale". In 1951 he began a long association with the Bedford area, being successively Rural Dean, Archdeacon of Bedford and then Suffragan Bishop. He died in post on 25 October 1976.
Edmund Burke
Writing to a friend in May 1795, Burke surveyed the causes of discontent: "I think I can hardly overrate the malignity of the principles of Protestant ascendency, as they affect Ireland; or of Indianism [i.e. corporate tyranny, as practiced by the British East Indies Company], as they affect these countries, and as they affect Asia; or of Jacobinism, as they affect all Europe, and the state of human society itself. The last is the greatest evil". By March 1796, however Burke had changed his mind: "Our Government and our Laws are beset by two different Enemies, which are sapping its foundations, Indianism, and Jacobinism. In some Cases they act separately, in some they act in conjunction: But of this I am sure; that the first is the worst by far, and the hardest to deal with; and for this amongst other reasons, that it weakens discredits, and ruins that force, which ought to be employed with the greatest Credit and Energy against the other; and that it furnishes Jacobinism with its strongest arms against all formal Government".
