George Stanfield Blake
George Stanfield Blake (1876–1940) was a British mineral and mining geologist, fluent in French, Italian, German and latterly his family understood Palestinian Arabic/Levantine Arabic, which aided his later survey work. Early career (1900–1922) On completing his degree at age 21, he worked as an assayer in London and at the Royal Mines of Elba. During the period of 1900/1901 to 1909 he was on staff at the Scientific and Technical Department of the Imperial Institute engaged in mineralogical studies of Crown colonies. Here, with Dunstan, thorianite from Ceylon was described as a new mineral and he published papers on baddeleyite and zirkelite from Ceylon and carnotite from South Australia. After this, he spent time in Matto Grosso, Brazil exploring for minerals, looking for gold at Timmins around Porcupine Lake, Ontario, and prospecting for petroleum in Newfoundland and Canada. On returning to England in 1915, he worked at Warrington as a mineral analyst and then at Sheffie ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Photograph Of George Stanfield Blake Geologist 1920s
A photograph (also known as a photo, or more generically referred to as an ''image'' or ''picture'') is an image created by light falling on a photosensitive surface, usually photographic film or an electronic image sensor. The process and practice of creating such images is called photography. Most photographs are now created using a smartphone or camera, which uses a lens to focus the scene's visible wavelengths of light into a reproduction of what the human eye would perceive. Etymology The word ''photograph'' was coined in 1839 by Sir John Herschel and is based on the Greek φῶς (''phos''), meaning "light", and γραφή (''graphê''), meaning "drawing, writing", together meaning "drawing with light". History The first permanent photograph, a contact-exposed copy of an engraving, was made in 1822 using the bitumen-based "heliography" process developed by Nicéphore Niépce. The first photographs of a real-world scene, made using a camera obscura, followed a few years ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Palestine (region)
The region of Palestine, also known as historic Palestine, is a geographical area in West Asia. It includes the modern states of Israel and Palestine, as well as parts of northwestern Jordan in some definitions. Other names for the region include Canaan, the Promised Land, the Land of Israel, or the Holy Land. The earliest written record Timeline of the name Palestine, referring to Palestine as a geographical region is in the ''Histories (Herodotus), Histories'' of Herodotus in the 5th century BCE, which calls the area ''Palaistine'', referring to the territory previously held by Philistia, a state that existed in that area from the 12th to the 7th century BCE. The Roman Empire conquered the region and in 6 CE established the province known as Judaea (Roman province), Judaea. In the aftermath of the Bar Kokhba revolt (132–136 CE), the province was renamed Syria Palaestina. In 390, during the Byzantine period, the region was split into the provinces of Palaestina Prima, Pal ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
White Paper Of 1939
The White Paper of 1939Occasionally also known as the MacDonald White Paper (e.g. Caplan, 2015, p.117) after Malcolm MacDonald, the British Colonial Secretary, who presided over its creation. was a policy paper issued by the British government, led by Neville Chamberlain, in response to the 1936–1939 Arab revolt in Palestine. After its formal approval in the House of Commons on 23 May 1939,by 268 votes to 179. it acted as the governing policy for Mandatory Palestine from 1939 to the 1948 British departure. After the war, the Mandate was referred to the United Nations. The policy, first drafted in March 1939, was prepared by the British government unilaterally as a result of the failure of the Arab–Zionist London Conference. The paper called for the establishment of a Jewish national home in an independent Palestinian state within 10 years, rejecting the Peel Commission's idea of partitioning Palestine. It also limited Jewish immigration to 75,000 for five years and rule ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Haganah
Haganah ( , ) was the main Zionist political violence, Zionist paramilitary organization that operated for the Yishuv in the Mandatory Palestine, British Mandate for Palestine. It was founded in 1920 to defend the Yishuv's presence in the region, and was formally disbanded in 1948, when it became the core force integrated into the Israel Defense Forces shortly after the Israeli Declaration of Independence. Formed out of previous existing militias, Haganah's original purpose was to Intercommunal conflict in Mandatory Palestine, defend Jewish settlements against Arab attacks; this was the case during the Jaffa riots, 1921 Jaffa riots, the 1929 Palestine riots, the Jaffa riots (April 1936), 1936 Jaffa riots, and the 1936–1939 Arab revolt in Palestine, among others. The paramilitary was under the control of the Jewish Agency for Israel, Jewish Agency, the official governmental body in charge of Palestine's Jewish community during the British era. Until the end of World War II, H ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Nuremberg Laws
The Nuremberg Laws (, ) were antisemitic and racist laws that were enacted in Nazi Germany on 15 September 1935, at a special meeting of the Reichstag convened during the annual Nuremberg Rally of the Nazi Party. The two laws were the Law for the Protection of German Blood and German Honour, which forbade marriages and extramarital intercourse between Jews and Germans and the employment of German females under 45 in Jewish households; and the Reich Citizenship Law, which declared that only those of German or related blood were eligible to be Reich citizens. The remainder were classed as state subjects without any citizenship rights. A supplementary decree outlining the definition of who was Jewish was passed on 14 November, and the Reich Citizenship Law officially came into force on that date. The laws were expanded on 26 November 1935 to include Romani and Black people. This supplementary decree defined Romani people as "enemies of the race-based state", the same category ...

Jemal Pasha
Ahmed Djemal (; ; 6 May 1872 – 21 July 1922), also known as Djemal Pasha or Cemâl Pasha, was an Ottoman military leader and one of the Three Pashas that ruled the Ottoman Empire during World War I. As an officer of the II Corps, he was stationed in Salonica where he developed political sympathies for the Committee of Union and Progress (CUP) reformers. He was initially praised by Christian missionaries and provided support to the Armenian victims of the Adana massacres. In the course of his army career Cemal developed a rivalry with Mustafa Kemal Atatürk, served in Salonica on the frontlines of the Balkan Wars and was given the martial law command of Constantinople after the Raid on the Sublime Porte. Cemal's authoritarian three year rule in Syria alienated the local population who opposed Turkish nationalism. His role in the Armenian genocide has been controversial as his policies were not as deadly as other CUP leaders; Cemal favored the forced assimilation of Armenian ...

Wadi Feynan
Wadi Feynan or Wadi Faynan () is a major wadi (seasonal river valley) and region in southern Jordan, on the border between Tafilah Governorate and Aqaba Governorate, Aqaba and Ma'an Governorates. It originates in the southern Jordanian Highlands with the confluence of Wadi Dana and Wadi Ghuweyr, and drains into the Dead Sea via Wadi Araba. Historically, the area had the largest Copper ore, copper deposits in the Southern Levant. Also has a number of significant early prehistoric sites. The rich copper deposits of Wadi Faynan became the basis for the rapid development of copper culture. Mining and smelting of ore began from the Chalcolithic period (4500–3100 BCE), and continued onward to the Mamluk Sultanate (Cairo), Mamluk period (1250–1516 CE). German scientists excavating the region in 1983 concluded that copper production in the region was on a scale unprecedented in the southeastern Mediterranean, with the possible exception of the copper mines of Cyprus.

Copper
Copper is a chemical element; it has symbol Cu (from Latin ) and atomic number 29. It is a soft, malleable, and ductile metal with very high thermal and electrical conductivity. A freshly exposed surface of pure copper has a pinkish-orange color. Copper is used as a conductor of heat and electricity, as a building material, and as a constituent of various metal alloys, such as sterling silver used in jewelry, cupronickel used to make marine hardware and coins, and constantan used in strain gauges and thermocouples for temperature measurement. Copper is one of the few metals that can occur in nature in a directly usable, unalloyed metallic form. This means that copper is a native metal. This led to very early human use in several regions, from . Thousands of years later, it was the first metal to be smelted from sulfide ores, ; the first metal to be cast into a shape in a mold, ; and the first metal to be purposely alloyed with another metal, tin, to create bronze, ...

Ancient Rome
In modern historiography, ancient Rome is the Roman people, Roman civilisation from the founding of Rome, founding of the Italian city of Rome in the 8th century BC to the Fall of the Western Roman Empire, collapse of the Western Roman Empire in the 5th century AD. It encompasses the Roman Kingdom (753–509 BC), the Roman Republic (50927 BC), and the Roman Empire (27 BC476 AD) until the fall of the western empire. Ancient Rome began as an Italic peoples, Italic settlement, traditionally dated to 753 BC, beside the River Tiber in the Italian peninsula. The settlement grew into the city and polity of Rome, and came to control its neighbours through a combination of treaties and military strength. It eventually controlled the Italian Peninsula, assimilating the Greece, Greek culture of southern Italy (Magna Graecia) and the Etruscans, Etruscan culture, and then became the dominant power in the Mediterranean region and parts of Europe.

Iron
Iron is a chemical element; it has symbol Fe () and atomic number 26. It is a metal that belongs to the first transition series and group 8 of the periodic table. It is, by mass, the most common element on Earth, forming much of Earth's outer and inner core. It is the fourth most abundant element in the Earth's crust, being mainly deposited by meteorites in its metallic state. Extracting usable metal from iron ores requires kilns or furnaces capable of reaching , about 500 °C (900 °F) higher than that required to smelt copper. Humans started to master that process in Eurasia during the 2nd millennium BC and the use of iron tools and weapons began to displace copper alloys – in some regions, only around 1200 BC. That event is considered the transition from the Bronze Age to the Iron Age. In the modern world, iron alloys, such as steel, stainless steel, cast iron and special steels, are by far the most common industrial metals, due to their mechan ...

Phosphate
Phosphates are the naturally occurring form of the element phosphorus. In chemistry, a phosphate is an anion, salt, functional group or ester derived from a phosphoric acid. It most commonly means orthophosphate, a derivative of orthophosphoric acid, phosphoric acid . The phosphate or orthophosphate ion is derived from phosphoric acid by the removal of three protons . Removal of one proton gives the dihydrogen phosphate ion while removal of two protons gives the hydrogen phosphate ion . These names are also used for salts of those anions, such as ammonium dihydrogen phosphate and trisodium phosphate.
