Gothic War (535–554)
The Gothic War between the Eastern Roman Empire during the reign of Emperor Justinian I and the Ostrogothic Kingdom of Italy took place from 535 to 554 in the Italian Peninsula, Dalmatia, Sardinia, Sicily and Corsica. It was one of the last of the many Gothic Wars against the Roman Empire. The war had its roots in the ambition of the Eastern Roman (Byzantine) Emperor Justinian I to recover the provinces of the former Western Roman Empire, which the Romans had lost to invading barbarian tribes in the previous century, during the Migration Period. The war followed the Eastern Roman reconquest of the province of Africa from the Vandals. Historians commonly divide the war into two phases: * From 535 to 540: ending with the fall of the Ostrogothic capital Ravenna and the apparent reconquest of Italy by the Byzantines. * From 540/541 to 553: a Gothic revival under Totila, suppressed only after a long struggle by the Byzantine general Narses, who also repelled an invasion in 554 by ...

Glorious Revolution
The Glorious Revolution; gd, Rèabhlaid Ghlòrmhor; cy, Chwyldro Gogoneddus , also known as the ''Glorieuze Overtocht'' or ''Glorious Crossing'' in the Netherlands, is the sequence of events leading to the deposition of King James II and VII of England and Scotland in November 1688, and his replacement by his daughter Mary II and her husband and James's nephew William III of Orange, de facto ruler of the Dutch Republic. A term first used by John Hampden (1653–1696), John Hampden in late 1689, it has been notable in the years since for having been described as the last successful invasion of England as well as an internal coup, with differing interpretations from the Dutch and English perspectives respectively. Despite his personal Catholicism, a religion opposed by the Protestant majority in England and Scotland, James became king in February 1685 with widespread support in both countries, since many feared that his exclusion would lead to a repetition of the 16391651 Wa ...

Linear Polarization
In electrodynamics, linear polarization or plane polarization of electromagnetic radiation is a confinement of the electric field vector or magnetic field vector to a given plane along the direction of propagation. The term ''linear polarization'' (French: ''polarisation rectiligne'') was coined by Augustin-Jean Fresnel in 1822.A. Fresnel, "Mémoire sur la double réfraction que les rayons lumineux éprouvent en traversant les aiguilles de cristal de roche suivant les directions parallèles à l'axe", read 9 December 1822; printed in H. de Senarmont, E. Verdet, and L. Fresnel (eds.), ''Oeuvres complètes d'Augustin Fresnel'', vol. 1 (1866), pp.731–51; translated as "Memoir on the double refraction that light rays undergo in traversing the needles of quartz in the directions parallel to the axis", , 2021 (open access); §9. See '' polarization'' and ''plane of polarization'' for more information. The orientation of a linearly polarized electromagn ...

French Academy Of Sciences
The French Academy of Sciences (French: ''Académie des sciences'') is a learned society, founded in 1666 by Louis XIV of France, Louis XIV at the suggestion of Jean-Baptiste Colbert, to encourage and protect the spirit of French Scientific method, scientific research. It was at the forefront of scientific developments in Europe in the 17th and 18th centuries, and is one of the earliest Academy of Sciences, Academies of Sciences. Currently headed by Patrick Flandrin (President of the Academy), it is one of the five Academies of the Institut de France. History The Academy of Sciences traces its origin to Colbert's plan to create a general academy. He chose a small group of scholars who met on 22 December 1666 in the King's library, near the present-day Bibliothèque nationale de France, Bibliothèque Nationals, and thereafter held twice-weekly working meetings there in the two rooms assigned to the group. The first 30 years of the Academy's existence were relatively informal ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Augustin-Jean Fresnel
Augustin-Jean Fresnel (10 May 1788 – 14 July 1827) was a French civil engineer and physicist whose research in optics led to the almost unanimous acceptance of the wave theory of light, excluding any remnant of Isaac Newton, Newton's corpuscular theory of light, corpuscular theory, from the late 1830s until the end of the 19th century. He is perhaps better known for inventing the Catadioptric system, catadioptric (reflective/refractive) Fresnel lens and for pioneering the use of "stepped" lenses to extend the visibility of lighthouses, saving countless lives at sea. The simpler Dioptrics, dioptric (purely refractive) stepped lens, first proposed by Georges-Louis Leclerc, Comte de Buffon, Count Buffon and independently reinvented by Fresnel, is used in screen magnifying glass, magnifiers and in condenser lenses for overhead projectors. By expressing Christiaan Huygens, Huygens's principle of secondary waves and Thomas Young (scientist), Young's principle of interference ( ...

Virginia
Virginia, officially the Commonwealth of Virginia, is a state in the Mid-Atlantic and Southeastern regions of the United States, between the Atlantic Coast and the Appalachian Mountains. The geography and climate of the Commonwealth are shaped by the Blue Ridge Mountains and the Chesapeake Bay, which provide habitat for much of its flora and fauna. The capital of the Commonwealth is Richmond; Virginia Beach is the most-populous city, and Fairfax County is the most-populous political subdivision. The Commonwealth's population was over 8.65million, with 36% of them living in the Baltimore–Washington metropolitan area. The area's history begins with several indigenous groups, including the Powhatan. In 1607, the London Company established the Colony of Virginia as the first permanent English colony in the New World. Virginia's state nickname, the Old Dominion, is a reference to this status. Slave labor and land acquired from displaced native tribes fueled the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Battle Of Great Bridge
The Battle of Great Bridge was fought December 9, 1775, in the area of Great Bridge, Virginia, early in the American Revolutionary War. The victory by colonial Virginia militia forces led to the departure of Royal Governor Lord Dunmore and any remaining vestiges of British power over the Colony of Virginia during the early days of the conflict. Following increasing political and military tensions in early 1775, both Dunmore and colonial rebel leaders recruited troops and engaged in a struggle for available military supplies. The struggle eventually focused on Norfolk, where Dunmore had taken refuge aboard a Royal Navy vessel. Dunmore's forces had fortified one side of a critical river crossing south of Norfolk at Great Bridge, while rebel forces had occupied the other side. In an attempt to break up the rebel gathering, Dunmore ordered an attack across the bridge, which was decisively repulsed. Colonel William Woodford, the Virginia militia commander at the battle, described it ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Patriot (American Revolution)
Patriots, also known as Revolutionaries, Continentals, Rebels, or American Whigs, were the colonists of the Thirteen Colonies who rejected British rule during the American Revolution, and declared the United States of America an independent nation in July 1776. Their decision was based on the political philosophy of republicanism—as expressed by such spokesmen as Thomas Jefferson, John Adams, and Thomas Paine. They were opposed by the Loyalists, who supported continued British rule. Patriots represented the spectrum of social, economic, and ethnic backgrounds. They included lawyers such as John Adams, students such as Alexander Hamilton, planters such as Thomas Jefferson and George Mason, merchants such as Alexander McDougall and John Hancock, and farmers such as Daniel Shays and Joseph Plumb Martin. They also included slaves and freemen such as Crispus Attucks, one of the first casualties of the American Revolution; James Armistead Lafayette, who served as a double agent ...

Loyalist (American Revolution)
Loyalists were colonists in the Thirteen Colonies who remained loyal to the British Crown during the American Revolutionary War, often referred to as Tories, Royalists or King's Men at the time. They were opposed by the Patriots, who supported the revolution, and called them "persons inimical to the liberties of America." Prominent Loyalists repeatedly assured the British government that many thousands of them would spring to arms and fight for the crown. The British government acted in expectation of that, especially in the southern campaigns in 1780–81. Britain was able to effectively protect the people only in areas where they had military control, and in return, the number of military Loyalists was significantly lower than what had been expected. Due to the conflicting political views, loyalists were often under suspicion of those in the British military, who did not know whom they could fully trust in such a conflicted situation; they were often looked down upon.

American Revolutionary War
The American Revolutionary War (April 19, 1775 – September 3, 1783), also known as the Revolutionary War or American War of Independence, was a major war of the American Revolution. Widely considered as the war that secured the independence of the United States, fighting began on April 19, 1775, followed by the Lee Resolution on July 2, 1776, and the Declaration of Independence on July 4, 1776. The American Patriots were supported by the Kingdom of France and, to a lesser extent, the Dutch Republic and the Spanish Empire, in a conflict taking place in North America, the Caribbean, and the Atlantic Ocean. Established by royal charter in the 17th and 18th centuries, the American colonies were largely autonomous in domestic affairs and commercially prosperous, trading with Britain and its Caribbean colonies, as well as other European powers via their Caribbean entrepôts. After British victory over the French in the Seven Years' War in 1763, tensions between the motherland and he ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
1775
Events Summary The American Revolutionary War began this year, with the first military engagement being the April 19 Battles of Lexington and Concord on the day after Paul Revere's now-legendary ride. The Second Continental Congress takes various steps toward organizing an American government, appointing George Washington commander-in-chief (June 14), Benjamin Franklin postmaster general (July 26) and creating a Continental Navy (October 13) and a Marine force (November 10) as landing troops for it, but as yet the 13 colonies have not declared independence, and both the British (June 12) and American (July 15) governments make laws. On July 6, Congress issues the Declaration of the Causes and Necessity of Taking Up Arms and on August 23, King George III of Great Britain declares the American colonies in rebellion, announcing it to Parliament on November 10. On June 17, two months into the colonial siege of Boston, at the Battle of Bunker Hill, just north of Boston, Br ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
