Hungary
Hungary ( hu, Magyarország ) is a landlocked country in Central Europe. Spanning of the Carpathian Basin, it is bordered by Slovakia to the north, Ukraine to the northeast, Romania to the east and southeast, Serbia to the south, Croatia and Slovenia to the southwest, and Austria to the west. Hungary has a population of nearly 9 million, mostly ethnic Hungarians and a significant Romani minority. Hungarian, the official language, is the world's most widely spoken Uralic language and among the few non-Indo-European languages widely spoken in Europe. Budapest is the country's capital and largest city; other major urban areas include Debrecen, Szeged, Miskolc, Pécs, and Győr. The territory of present-day Hungary has for centuries been a crossroads for various peoples, including Celts, Romans, Germanic tribes, Huns, West Slavs and the Avars. The foundation of the Hungarian state was established in the late 9th century AD with the conquest of the Carpathian Basin by Hungar ...

Tungsram
Tungsram was a manufacturing company located in Hungary and known for their light bulbs and electronics. Established in Újpest (today part of Budapest, Hungary) in 1896, it initially produced telephones, wires and switchboards. The name "Tungsram" is a portmanteau of "tungsten" and "wolfram" (the two common names of the metal used for making light bulb filaments). Before becoming nationalized by the Communist government in 1945, the company was the world's third largest manufacturer of light bulbs and radiotubes, after the American General Electric and RCA companies. History On 13 December 1904, Hungarian Sándor Just and Croatian Franjo Hanaman were granted Hungarian patent no. 34541 for the world's first tungsten filament bulb that lasted longer and produced brighter light than a carbon filament. The co-inventors licensed their patent to the company, which came to be named Tungsram after the eponymous tungsten incandescent bulbs, which are still called Tungsram bulbs in m ...

Holocaust
The Holocaust, also known as the Shoah, was the genocide of European Jews during World War II. Between 1941 and 1945, Nazi Germany and its collaborators systematically murdered some six million Jews across German-occupied Europe; around two-thirds of Europe's Jewish population. The murders were carried out in pogroms and mass shootings; by a policy of extermination through labor in concentration camps; and in gas chambers and gas vans in German extermination camps, chiefly Auschwitz-Birkenau, Bełżec, Chełmno, Majdanek, Sobibór, and Treblinka in occupied Poland. Germany implemented the persecution in stages. Following Adolf Hitler's appointment as chancellor on 30 January 1933, the regime built a network of concentration camps in Germany for political opponents and those deemed "undesirable", starting with Dachau on 22 March 1933. After the passing of the Enabling Act on 24 March, which gave Hitler dictatorial plenary powers, the government began isolating Je ...

Yad Vashem
Yad Vashem ( he, יָד וַשֵׁם; literally, "a memorial and a name") is Israel's official memorial to the victims of the Holocaust. It is dedicated to preserving the memory of the Jews who were murdered; honoring Jews who fought against their Nazi oppressors and Gentiles who selflessly aided Jews in need; and researching the phenomenon of the Holocaust in particular and genocide in general, with the aim of avoiding such events in the future. Established in 1953, Yad Vashem is located on the western slope of Mount Herzl, also known as the Mount of Remembrance, a height in western Jerusalem, above sea level and adjacent to the Jerusalem Forest. The memorial consists of a complex containing two types of facilities: some dedicated to the scientific study of the Holocaust and genocide in general, and memorials and museums catering to the needs of the larger public. Among the former there are a research institute with archives, a library, a publishing house, and an educational ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Righteous Among The Nations
Righteous Among the Nations ( he, חֲסִידֵי אֻמּוֹת הָעוֹלָם, ; "righteous (plural) of the world's nations") is an honorific used by the State of Israel to describe non-Jews who risked their lives during the Holocaust to save Jews from extermination by the Nazis for altruistic reasons. The term originates with the concept of " righteous gentiles", a term used in rabbinic Judaism to refer to non-Jews, called , who abide by the Seven Laws of Noah. Bestowing When Yad Vashem, the Shoah Martyrs' and Heroes' Remembrance Authority, was established in 1953 by the Knesset, one of its tasks was to commemorate the "Righteous Among the Nations". The Righteous were defined as non-Jews who risked their lives to save Jews during the Holocaust. Since 1963, a commission headed by a justice of the Supreme Court of Israel has been charged with the duty of awarding the honorary title "Righteous Among the Nations". Guided in its work by certain criteria, the commission metic ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
State Of Israel
Israel (; he, יִשְׂרָאֵל, ; ar, إِسْرَائِيل, ), officially the State of Israel ( he, מְדִינַת יִשְׂרָאֵל, label=none, translit=Medīnat Yīsrāʾēl; ), is a country in Western Asia. It is situated on the southeastern shore of the Mediterranean Sea and the northern shore of the Red Sea, and shares borders with Lebanon to the north, Syria to the northeast, Jordan to the east, and Egypt to the southwest. Israel also is bordered by the Palestinian territories of the West Bank and the Gaza Strip to the east and west, respectively. Tel Aviv is the economic and technological center of the country, while its seat of government is in its proclaimed capital of Jerusalem, although Israeli sovereignty over East Jerusalem is unrecognized internationally. The land held by present-day Israel witnessed some of the earliest human occupations outside Africa and was among the earliest known sites of agriculture. It was inhabited by the Canaanites ...

BIPM
The International Bureau of Weights and Measures (french: Bureau international des poids et mesures, BIPM) is an intergovernmental organisation, through which its 59 member-states act together on measurement standards in four areas: chemistry, ionising radiation, physical metrology, and coordinated universal time. It is based in Saint-Cloud, Paris, France. The organisation has been referred to as IBWM (from its name in English) in older literature. Structure The BIPM is supervised by the International Committee for Weights and Measures (french: Comité international des poids et mesures, CIPM), a committee of eighteen members that meet normally in two sessions per year, which is in turn overseen by the General Conference on Weights and Measures (french: Conférence générale des poids et mesures, CGPM) that meets in Paris usually once every four years, consisting of delegates of the governments of the Member States and observers from the Associates of the CGPM. These organs ar ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
CGPM
The General Conference on Weights and Measures (GCWM; french: Conférence générale des poids et mesures, CGPM) is the supreme authority of the International Bureau of Weights and Measures (BIPM), the intergovernmental organization established in 1875 under the terms of the Metre Convention through which member states act together on matters related to measurement science and measurement standards. The CGPM is made up of delegates of the governments of the member states and observers from the Associates of the CGPM. Under its authority, the International Committee for Weights and Measures (ICWM; ) executes an exclusive direction and supervision of the BIPM. Initially the Metre Convention was only concerned with the kilogram and the metre, but in 1921 the scope of the treaty was extended to accommodate all physical measurements and hence all aspects of the metric system. In 1960 the 11th CGPM approved the International System of Units, usually known as "SI". The General Confer ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Light-emitting Diode
A light-emitting diode (LED) is a semiconductor device that emits light when current flows through it. Electrons in the semiconductor recombine with electron holes, releasing energy in the form of photons. The color of the light (corresponding to the energy of the photons) is determined by the energy required for electrons to cross the band gap of the semiconductor. White light is obtained by using multiple semiconductors or a layer of light-emitting phosphor on the semiconductor device. Appearing as practical electronic components in 1962, the earliest LEDs emitted low-intensity infrared (IR) light. Infrared LEDs are used in remote-control circuits, such as those used with a wide variety of consumer electronics. The first visible-light LEDs were of low intensity and limited to red. Early LEDs were often used as indicator lamps, replacing small incandescent bulbs, and in seven-segment displays. Later developments produced LEDs available in visible, ultraviolet (UV) ...
