Document 2: Germany: After Germany surrendered, the Allies partitioned Berlin and Germany's remaining territory into four military occupation zones. The western sectors, controlled by France, the United Kingdom, and the United States, were merged on 23 May 1949 to form the Federal Republic of Germany (Bundesrepublik Deutschland); on 7 October 1949, the Soviet Zone became the German Democratic Republic (Deutsche Demokratische Republik). They were informally known as West Germany and East Germany. East Germany selected East Berlin as its capital, while West Germany chose Bonn as a provisional capital, to emphasize its stance that the two - state solution was an artificial and temporary status quo.
Document 3: History of Germany (1945–1990): The intended governing body of Germany was called the Allied Control Council. The commanders - in - chief exercised supreme authority in their respective zones and acted in concert on questions affecting the whole country. Berlin, which lay in the Soviet (eastern) sector, was also divided into four sectors with the Western sectors later becoming West Berlin and the Soviet sector becoming East Berlin, capital of East Germany.
Document 4: Periodic table: All the elements from atomic numbers 1 (hydrogen) through 118 (oganesson) have been either discovered or synthesized, completing the first seven rows of the periodic table. The first 98 elements exist in nature, although some are found only in trace amounts and others were synthesized in laboratories before being found in nature. Atomic numbers for elements 99 to 118 have only been synthesized in laboratories or nuclear reactors. The synthesis of elements having higher atomic numbers is currently being pursued: these elements would begin an eighth row, and theoretical work has been done to suggest possible candidates for this extension. Numerous synthetic radionuclides of naturally occurring elements have also been produced in laboratories.
Document 5: Alsace: Alsace-Lorraine was occupied by Germany in 1940 during the Second World War. Although Germany never formally annexed Alsace-Lorraine, it was incorporated into the Greater German Reich, which had been restructured into Reichsgaue. Alsace was merged with Baden, and Lorraine with the Saarland, to become part of a planned Westmark. During the war, 130,000 young men from Alsace and Lorraine were inducted into the German army against their will (malgré-nous) and in some cases, the Waffen SS. Some of the latter were involved in war crimes such as the Oradour-sur-Glane massacre. Most of them perished on the eastern front. The few that could escape fled to Switzerland or joined the resistance. In July 1944, 1500 malgré-nous were released from Soviet captivity and sent to Algiers, where they joined the Free French Forces.
Document 6: Roentgenium: Roentgenium was first synthesized by an international team led by Sigurd Hofmann at the Gesellschaft für Schwerionenforschung (GSI) in Darmstadt, Germany, on December 8, 1994. The team bombarded a target of bismuth-209 with accelerated nuclei of nickel-64 and detected three nuclei of the isotope roentgenium-272:
Document 7: Peter Armbruster: Peter Armbruster (born 25 July 1931 in Dachau, Bavaria) is a physicist at the Gesellschaft für Schwerionenforschung (GSI) facility in Darmstadt, Germany, and is credited with co-discovering elements 107 (bohrium), 108 (hassium), 109 (meitnerium), 110 (darmstadtium), 111 (roentgenium), and 112 (copernicium) with research partner Gottfried Münzenberg.
Document 8: Mendelevium: Mendelevium was discovered by bombarding einsteinium with alpha particles in 1955, the same method still used to produce it today. It was named after Dmitri Mendeleev, father of the periodic table of the chemical elements. Using available microgram quantities of the isotope einsteinium-253, over a million mendelevium atoms may be produced each hour. The chemistry of mendelevium is typical for the late actinides, with a preponderance of the +3 oxidation state but also an accessible +2 oxidation state. Owing to the small amounts of produced mendelevium and all of its isotopes having relatively short half-lives, there are currently no uses for it outside basic scientific research.
Document 9: Friedrich Ernst Dorn: Friedrich Ernst Dorn (27 July 1848 – 16 December 1916) was a German physicist who was the first to discover that a radioactive substance, later named radon, is emitted from radium.
Document 10: Uranium: A team led by Enrico Fermi in 1934 observed that bombarding uranium with neutrons produces the emission of beta rays (electrons or positrons from the elements produced; see beta particle). The fission products were at first mistaken for new elements of atomic numbers 93 and 94, which the Dean of the Faculty of Rome, Orso Mario Corbino, christened ausonium and hesperium, respectively. The experiments leading to the discovery of uranium's ability to fission (break apart) into lighter elements and release binding energy were conducted by Otto Hahn and Fritz Strassmann in Hahn's laboratory in Berlin. Lise Meitner and her nephew, the physicist Otto Robert Frisch, published the physical explanation in February 1939 and named the process "nuclear fission". Soon after, Fermi hypothesized that the fission of uranium might release enough neutrons to sustain a fission reaction. Confirmation of this hypothesis came in 1939, and later work found that on average about 2.5 neutrons are released by each fission of the rare uranium isotope uranium-235. Further work found that the far more common uranium-238 isotope can be transmuted into plutonium, which, like uranium-235, is also fissile by thermal neutrons. These discoveries led numerous countries to begin working on the development of nuclear weapons and nuclear power.
Document 11: Maxime Weygand: Weygand mainly served as a staff officer to Ferdinand Foch in World War I. Weygand initially fought against the Germans during the invasion of France in 1940, but then signed an armistice with and partially collaborated with the Germans as part of the Vichy France regime before being arrested by the Germans for not fully collaborating with them.
Document 12: Albert Ghiorso: Albert Ghiorso (July 15, 1915 -- December 26, 2010) was an American nuclear scientist and co-discoverer of a record 12 chemical elements on the periodic table. His research career spanned five decades, from the early 1940s to the late 1990s.
Document 13: Niels Bohr: Bohr founded the Institute of Theoretical Physics at the University of Copenhagen, now known as the Niels Bohr Institute, which opened in 1920. Bohr mentored and collaborated with physicists including Hans Kramers, Oskar Klein, George de Hevesy, and Werner Heisenberg. He predicted the existence of a new zirconium-like element, which was named hafnium, after the Latin name for Copenhagen, where it was discovered. Later, the element bohrium was named after him.
Document 14: Alsace-Lorraine: Under the German Empire of 1871–1918, the annexed territory constituted the "Reichsland" or Imperial Territory of (German for Alsace-Lorraine). The area was administered directly from Berlin, but was granted limited autonomy in 1911. This included its constitution and state assembly, its own flag, and the ("Alsatian Flag Song") as its anthem.
Document 15: Philippe Pétain: With the imminent Fall of France in June 1940 in World War II, Pétain was appointed President of the Ministerial Council by President Lebrun at Bordeaux, and the Cabinet resolved to sign an armistice agreement with Germany. The entire government subsequently moved briefly to Clermont-Ferrand, then to the spa town of Vichy in central France. His government voted to transform the discredited French Third Republic into the French State, an authoritarian regime that collaborated with the Axis, although it refused to declare war on the UK after the attack on Mers-el-Kebir and even remained formally at war with Germany. After Germany and Italy occupied and disarmed France in November 1942, Pétain became a mere puppet of the German military administration.
