Earth (otherwise known as the world,[n 5] in Greek: Γαῖα Gaia,[n 6]or in Latin: Terra[26]) is the third planet from the Sun, thedensest planet in the Solar System, the largest of the SolarSystem's four terrestrial planets, and the only astronomical objectknown to harbor life. According to radiometric dating and othersources of evidence, Earth formed about 4.54 billion yearsago.[27][28][29] Earth gravitationally interacts with other objectsin space, especially the Sun and the Moon. During one orbit aroundthe Sun, Earth rotates about its own axis 366.26 times, creating365.26 solar days or one sidereal year.[n 7] Earth's axis ofrotation is tilted 23.4° away from the perpendicular of its orbitalplane, producing seasonal variations on the planet's surface with aperiod of one tropical year (365.24 solar days).[30] The Moon isEarth's only permanent natural satellite. Its gravitationalinteraction with Earth causes ocean tides, stabilizes theorientation of Earth's rotational axis, and gradually slows Earth'srotational rate.[31] Earth's lithosphere is divided into severalrigid tectonic plates that migrate across the surface over periodsof many millions of years. 71% of Earth's surface is covered withwater,[32] with the remainder consisting of continents and islandsthat together have many lakes and other sources of water thatcontribute to the hydrosphere. Earth's polar regions are mostlycovered with ice, including the Antarctic ice sheet and the sea iceof the Arctic ice pack. Earth's interior remains active with asolid iron inner core, a liquid outer core that generates themagnetic field, and a convecting mantle that drives platetectonics. Within its first billion years,[33] life appeared inEarth's oceans and began to affect its atmosphere and surface,leading to the proliferation of aerobic and anaerobic organisms.Since then, the combination of Earth's distance from the Sun, itsphysical properties and its geological history have allowed life tothrive and evolve. The earliest undisputed life on Earth arose atleast 3.5 billion years ago. Earlier physical evidence of lifeincludes biogenic graphite in 3.7 billion-year-old metasedimentaryrocks discovered in southwestern Greenland, as well as "remains ofbiotic life" found in 4.1 billion-year-old rocks in WesternAustralia.[34][35] Earth's biodiversity has expanded continuallyexcept when interrupted by mass extinctions.[36] Although scholarsestimate that over 99% of all species of life (over fivebillion)[37] that ever lived on Earth are extinct,[38][39] thereare still an estimated 10–14 million extant species,[40][41] ofwhich about 1.2 million have been documented and over 86% have notyet been described.[42] More recently, in May 2016, scientistsreported that 1 trillion species are estimated to be on Earthcurrently with only one-thousandth of one percent described.[43]Over 7.3 billion humans[44] live on Earth and depend on itsbiosphere and minerals for their survival. Earth's human populationis divided among about 200 sovereign states that interact throughdiplomacy, conflict, travel, trade, and communication media.

World War I History 3.1 APK
World War I (WWI or WW1), also known as the First World War, or theGreat War, was a global war centred in Europe that began on 28 July1914 and lasted until 11 November 1918. More than 70 millionmilitary personnel, including 60 million Europeans, were mobilisedin one of the largest wars in history.[5][6] Over 9 millioncombatants and 7 million civilians died as a result of the war(including the victims of a number of genocides), a casualty rateexacerbated by the belligerents' technological and industrialsophistication, and the tactical stalemate caused by trenchwarfare, a grueling form of warfare in which the defender held theadvantage. It was one of the deadliest conflicts in history, andpaved the way for major political changes, including revolutions inmany of the nations involved.[7] The war drew in all the world’seconomic great powers,[8] assembled in two opposing alliances: theAllies (based on the Triple Entente of the United Kingdom/BritishEmpire, France and the Russian Empire) and the Central Powers ofGermany and Austria-Hungary. Although Italy had also been a memberof the Triple Alliance alongside Germany and Austria-Hungary, itdid not join the Central Powers, as Austria-Hungary had taken theoffensive against the terms of the alliance.[9] These allianceswere reorganised and expanded as more nations entered the war:Italy, Japan and the United States joined the Allies, while theOttoman Empire and Bulgaria joined the Central Powers.
World War II History 4.1 APK
World War II (WWII or WW2), also known as the Second World War, wasa global war that lasted from 1939 to 1945, though relatedconflicts began earlier. It involved the vast majority of theworld's nations—including all of the great powers—eventuallyforming two opposing military alliances: the Allies and the Axis.It was the most widespread war in history, and directly involvedmore than 100 million people from over 30 countries. In a state of"total war", the major participants threw their entire economic,industrial, and scientific capabilities behind the war effort,erasing the distinction between civilian and military resources.Marked by mass deaths of civilians, including the Holocaust (inwhich approximately 11 million people were killed)[1][2] and thestrategic bombing of industrial and population centres (in whichapproximately one million were killed, and which included theatomic bombings of Hiroshima and Nagasaki),[3] it resulted in anestimated 50 million to 85 million fatalities. These made World WarII the deadliest conflict in human history.[4] The Empire of Japanaimed to dominate Asia and the Pacific and was already at war withthe Republic of China in 1937,[5] but the world war is generallysaid to have begun on 1 September 1939[6] with the invasion ofPoland by Germany and subsequent declarations of war on Germany byFrance and the United Kingdom. From late 1939 to early 1941, in aseries of campaigns and treaties, Germany conquered or controlledmuch of continental Europe, and formed the Axis alliance with Italyand Japan. Based on the Molotov–Ribbentrop Pact of August 1939,Germany and the Soviet Union partitioned and annexed territories oftheir European neighbours, Poland, Finland, Romania and the Balticstates. The war continued primarily between the European Axispowers and the United Kingdom and the British Commonwealth, withcampaigns including the North Africa and East Africa campaigns, theaerial Battle of Britain, the Blitz bombing campaign, the BalkanCampaign as well as the long-running Battle of the Atlantic. InJune 1941, the European Axis powers launched an invasion of theSoviet Union, opening the largest land theatre of war in history,which trapped the major part of the Axis' military forces into awar of attrition. In December 1941, Japan attacked the UnitedStates and European territories in the Pacific Ocean, and quicklyconquered much of the Western Pacific.
Albert Einstein Biography 3.0 APK
Albert Einstein (14 March 1879 – 18 April 1955) was a German-borntheoretical physicist. He developed the general theory ofrelativity, one of the two pillars of modern physics (alongsidequantum mechanics).[2][4]:274 Einstein's work is also known for itsinfluence on the philosophy of science.[5][6] Einstein is bestknown in popular culture for his mass–energy equivalence formula E= mc2 (which has been dubbed "the world's most famousequation").[7] He received the 1921 Nobel Prize in Physics for his"services to theoretical physics", in particular his discovery ofthe law of the photoelectric effect, a pivotal step in theevolution of quantum theory.[8] Near the beginning of his career,Einstein thought that Newtonian mechanics was no longer enough toreconcile the laws of classical mechanics with the laws of theelectromagnetic field. This led to the development of his specialtheory of relativity. He realized, however, that the principle ofrelativity could also be extended to gravitational fields, and withhis subsequent theory of gravitation in 1916, he published a paperon general relativity. He continued to deal with problems ofstatistical mechanics and quantum theory, which led to hisexplanations of particle theory and the motion of molecules. Healso investigated the thermal properties of light which laid thefoundation of the photon theory of light. In 1917, Einstein appliedthe general theory of relativity to model the large-scale structureof the universe.[9][10]
Ancient Greece History 2.9 APK
Ancient Greece was a civilization belonging to a period of Greekhistory that lasted from the Archaic period of the 8th to 6thcenturies BC to the end of antiquity (c. 600 AD). Immediatelyfollowing this period was the beginning of the Early Middle Agesand the Byzantine era. Included in ancient Greece is the period ofClassical Greece, which flourished during the 5th to 4th centuriesBC. Classical Greece began with the repelling of a Persian invasionby Athenian leadership. Because of conquests by Alexander the Greatof Macedonia, Hellenistic civilization flourished from Central Asiato the western end of the Mediterranean Sea. Classical Greekculture, especially philosophy, had a powerful influence on theRoman Empire, which carried a version of it to many parts of theMediterranean Basin and Europe. For this reason Classical Greece isgenerally considered to be the seminal culture which provided thefoundation of modern Western culture and is considered as thecradle of Western civilization.
History of Nazism 2.3 APK
National Socialism (German: Nationalsozialismus), more commonlyknown as Nazism (/ˈnaːtsɪzᵊm/), is the ideology and practiceassociated with the 20th-century German Nazi Party and Nazi stateas well as other far-right groups. Usually characterized as a formof fascism that incorporates scientific racism and anti-Semitism,Nazism developed out of the influences of Pan-Germanism, theVölkisch German nationalist movement, and the anti-communistFreikorps paramilitary groups that emerged during the WeimarRepublic after German defeat in World War I. Nazism subscribed totheories of racial hierarchy and Social Darwinism. Germanic peoples(called the Nordic Race) were depicted as the purest of the Aryanrace, and were therefore the master race. Opposed to bothcapitalism and communism, it aimed to overcome social divisions,with all parts of a homogeneous society seeking national unity andtraditionalism. Nazism also vigorously pursued what it viewed ashistorically German territory under the doctrine of Pan-Germanism(or Heim ins Reich), as well as additional lands for Germanexpansion under the doctrine of Lebensraum. The term "NationalSocialism" arose out of attempts to create a nationalistredefinition of "socialism", as an alternative to bothinternationalist Marxist socialism and free market capitalism. TheNazis sought to achieve this by a "people's community"(Volksgemeinschaft) with the aim of uniting all Germans as nationalcomrades, whilst excluding those deemed either to be communityaliens or "foreign peoples" (Fremdvölkische). It rejected theMarxist concept of class struggle, opposed ideas of class equalityand international solidarity, and sought to defend private propertyand businesses. The Nazi Party was founded as the Pan-Germannationalist and antisemitic German Workers' Party on 5 January1919. By the early 1920s, Adolf Hitler assumed control of theorganization and renamed it the National Socialist German Workers'Party (Nationalsozialistische Deutsche Arbeiterpartei, NSDAP) tobroaden its appeal. The National Socialist Program, adopted in1920, called for a united Greater Germany that would denycitizenship to Jews or those of Jewish descent, while alsosupporting land reform and the nationalization of some industries.In Mein Kampf, written in 1924, Hitler outlined the antisemitismand anti-communism at the heart of his political philosophy, aswell as his disdain for parliamentary democracy and his belief inGermany’s right to territorial expansion. In 1933, with the supportof the elites, Hitler became Chancellor of Germany and the Nazisgradually established a one-party state, under which Jews,political opponents and other "undesirables" elements weremarginalized, with several millions eventually imprisoned andkilled. Hitler purged the party’s more socially and economicallyradical factions in the mid-1934 Night of the Long Knives and,after the death of President Hindenburg, political power wasconcentrated in his hands, as Führer or "leader". Following theHolocaust and German defeat in World War II, only a few fringeracist groups, usually referred to as neo-Nazis, still describethemselves as following National Socialism.
History of the United States of America 2.7 APK
The date of the start of the history of the United States is asubject of constant debate among historians. Older textbooks startwith the arrival of Christopher Columbus in 1492 and emphasize theEuropean background, or they start around 1600 and emphasize theAmerican frontier. In recent decades American schools anduniversities typically have shifted back in time to include more onthe colonial period and much more on the prehistory of the Nativepeoples. Indigenous people lived in what is now the United Statesfor thousands of years before European colonists began to arrive,mostly from England, after 1600. The Spanish had small settlementsin Florida and the Southwest, and the French along the MississippiRiver and the Gulf Coast. By the 1770s, thirteen British coloniescontained two and a half million people along the Atlantic coasteast of the Appalachian Mountains. In the 1760s the Britishgovernment imposed a series of new taxes while rejecting theAmerican argument that any new taxes had to be approved by thepeople (see Stamp Act 1765). Tax resistance, especially the BostonTea Party (1774), led to punitive laws (the Intolerable Acts) byParliament designed to end self-government in Massachusetts.American Patriots (as they called themselves) adhered to apolitical ideology called republicanism that emphasized civic duty,virtue, and opposition to corruption, fancy luxuries andaristocracy.
History of Canada 1.8 APK
The history of Canada covers the period from the arrival ofPaleo-Indians thousands of years ago to the present day. Canada hasbeen inhabited for millennia by distinctive groups of Aboriginalpeoples, with distinct trade networks, spiritual beliefs, andstyles of social organization. Some of these civilizations had longfaded by the time of the first European arrivals and have beendiscovered through archaeological investigations. Various treatiesand laws have been enacted between European settlers and theAboriginal populations. Beginning in the late 15th century, Frenchand British expeditions explored, and later settled, along theAtlantic Coast. France ceded nearly all of its colonies in NorthAmerica to Britain in 1763 after the Seven Years' War. In 1867,with the union of three British North American colonies throughConfederation, Canada was formed as a federal dominion of fourprovinces. This began an accretion of provinces and territories anda process of increasing autonomy from the British Empire, whichbecame official with the Statute of Westminster of 1931 andcompleted in the Canada Act of 1982, which severed the vestiges oflegal dependence on the British parliament.
Nazi concentration camps History 2.4 APK
Nazi Germany maintained concentration camps (German:Konzentrationslager [kɔntsɛntʁaˈtsi̯oːnsˌlaːɡɐ], KZ or KL)throughout the territories it controlled. The first Naziconcentration camps were erected in Germany in March 1933immediately after Hitler became Chancellor and his Nazi Party wasgiven control over the police through Reich Interior MinisterWilhelm Frick and Prussian Acting Interior Minister HermannGöring.[2] Used to hold and torture political opponents and unionorganizers, the camps initially held around 45,000 prisoners.[3]Heinrich Himmler's SS took full control of the police andconcentration camps throughout Germany in 1934–35.[4] Himmlerexpanded the role of the camps to holding so-called "raciallyundesirable elements" of German society, such as Jews, criminals,homosexuals, and Romani.[5] The number of people in camps, whichhad fallen to 7,500, grew again to 21,000 by the start of World WarII[6] and peaked at 715,000 in January 1945.[7] This app is abouthistory and for research Purpose .
