Ernst David Bergmann
Ernst David Bergmann ( he, ארנסט דוד ברגמן; 1903 – April 6, 1975) was an Israeli nuclear scientist and chemist. He is often considered the father of the Israeli nuclear program. Biography Ernst David Bergmann was born in Germany, His father, Judah Bergmann, was a rabbi. He studied chemistry at the University of Berlin under Wilhelm Schlenk. He was awarded his Ph.D. in 1927. Bergmann continued to work at the university and wrote the "Comprehensive Manual of Organic Chemistry" (''Ausführliches Lehrbuch der Organischen Chemie'') together with Schlenk. The two-volume manual was published in 1932 and 1939, respectively; however, because Bergmann was Jewish his name to be removed from the title page of the second volume. Bergmann left for London in 1933 soon after the Nazis came to power, and began work with chemist and Zionist leader Chaim Weizmann. He turned down an offer of a position at Oxford from Sir Robert Robinson, an event that Sir Robinson recalled year ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
German Empire
The German Empire (),Herbert Tuttle wrote in September 1881 that the term "Reich" does not literally connote an empire as has been commonly assumed by English-speaking people. The term literally denotes an empire – particularly a hereditary empire led by an emperor, although has been used in German to denote the Roman Empire because it had a weak hereditary tradition. In the case of the German Empire, the official name was , which is properly translated as "German Empire" because the official position of head of state in the constitution of the German Empire was officially a "presidency" of a confederation of German states led by the King of Prussia who would assume "the title of German Emperor" as referring to the German people, but was not emperor of Germany as in an emperor of a state. –The German Empire" ''Harper's New Monthly Magazine''. vol. 63, issue 376, pp. 591–603; here p. 593. also referred to as Imperial Germany, the Second Reich, as well as simply Germany, ...

Nuclear Weapons And Israel
The State of Israel is widely believed to possess nuclear weapons. Estimates of Israel's stockpile range between 80 and 400 nuclear warheads, and the country is believed to possess the ability to deliver them in several methods, including by aircraft, as submarine-launched cruise missiles, and via the Jericho series of intermediate to intercontinental range ballistic missiles. Its first deliverable nuclear weapon is thought to have been completed in late 1966 or early 1967; which would make it the sixth country in the world to have developed them. However, Israel maintains a policy of deliberate ambiguity, never officially denying nor admitting to having nuclear weapons, instead repeating over the years that "Israel will not be the first country to introduce nuclear weapons to the Middle East". Israel has also declined to sign the Treaty on the Non-Proliferation of Nuclear Weapons (NPT), despite international pressure to do so, saying that would be contrary to its national ...

Organic Chemistry
Organic chemistry is a subdiscipline within chemistry involving the scientific study of the structure, properties, and reactions of organic compounds and organic materials, i.e., matter in its various forms that contain carbon atoms.Clayden, J.; Greeves, N. and Warren, S. (2012) ''Organic Chemistry''. Oxford University Press. pp. 1–15. . Study of structure determines their structural formula. Study of properties includes physical and chemical properties, and evaluation of chemical reactivity to understand their behavior. The study of organic reactions includes the chemical synthesis of natural products, drugs, and polymers, and study of individual organic molecules in the laboratory and via theoretical ( in silico) study. The range of chemicals studied in organic chemistry includes hydrocarbons (compounds containing only carbon and hydrogen) as well as compounds based on carbon, but also containing other elements, especially oxygen, nitrogen, sulfur, phosphorus (included in ...

Mandatory Palestine
Mandatory Palestine ( ar, فلسطين الانتدابية '; he, פָּלֶשְׂתִּינָה (א״י) ', where "E.Y." indicates ''’Eretz Yiśrā’ēl'', the Land of Israel) was a geopolitical entity established between 1920 and 1948 in the region of Palestine under the terms of the League of Nations Mandate for Palestine. During the First World War (1914–1918), an Arab uprising against Ottoman rule and the British Empire's Egyptian Expeditionary Force under General Edmund Allenby drove the Ottoman Turks out of the Levant during the Sinai and Palestine Campaign. The United Kingdom had agreed in the McMahon–Hussein Correspondence that it would honour Arab independence if the Arabs revolted against the Ottoman Turks, but the two sides had different interpretations of this agreement, and in the end, the United Kingdom and France divided the area under the Sykes–Picot Agreementan act of betrayal in the eyes of the Arabs.

Aliyah
Aliyah (, ; he, עֲלִיָּה ''ʿălīyyā'', ) is the immigration of Jews from Jewish diaspora, the diaspora to, historically, the geographical Land of Israel, which is in the modern era chiefly represented by the Israel, State of Israel. Traditionally described as "the act of going up" (towards the Jerusalem in Judaism, Jewish holy city of Jerusalem), moving to the Land of Israel or "making aliyah" is one of the most basic tenets of Zionism.

Originally of strategic significance due to its controlling location on the upper reaches of the River Thames at its junction with the River Cherwell, the town grew in national importance during the early Norman period, and in the late 12th century became home to the fledgling University of Oxford. The city was besieged during The Anarchy in 1142. The university rose to domina ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Chaim Weizmann
Chaim Azriel Weizmann ( he, חיים עזריאל ויצמן ', russian: Хаим Евзорович Вейцман, ''Khaim Evzorovich Veytsman''; 27 November 1874 – 9 November 1952) was a Russian-born biochemist, Zionist leader and Israeli statesman who served as president of the Zionist Organization and later as the first president of Israel. He was elected on 16 February 1949, and served until his death in 1952. Weizmann was fundamental in obtaining the Balfour Declaration and later convincing the United States government to recognize the newly formed State of Israel. As a biochemist, Weizmann is considered to be the 'father' of industrial fermentation. He developed the acetone–butanol–ethanol fermentation process, which produces acetone, n-butanol and ethanol through bacterial fermentation. His acetone production method was of great importance in the manufacture of cordite explosive propellants for the British war industry during World War I. He founded the Sieff ...
