Science And Technology In Nazi Germany
The position of science and technology in Nazi Germany was completely determined by party instructions and the political atmosphere established in the country. The state and party apparatuses, largely educated people from the lower classes of society, due to their inherent distrust and unfriendly attitude towards any knowledge, in principle did not contribute to the progress of science. On May 1, 1934, the Bernhard Rust (''Rust, Reichs- und preußischen Minister für Wissenschaft, Erziehung und Volksbildung'') was appointed Minister of Science, Education and Culture, who was charged with the responsibility of leading science in the spirit of party ideology and preparing for war. Encouraged, mainly, any science that gives an obvious result. The significance of fundamental science was not understood by the leaders of Nazi Germany. After the capture of the northern regions of France, Hitler, who considered his immediate political tasks (see Mein Kampf) completed, gave instructions ...

Jet Engine
A jet engine is a type of reaction engine discharging a fast-moving jet of heated gas (usually air) that generates thrust by jet propulsion. While this broad definition can include rocket, Pump-jet, water jet, and hybrid propulsion, the term typically refers to an internal combustion airbreathing jet engine such as a turbojet, turbofan, ramjet, or pulse jet engine, pulse jet. In general, jet engines are internal combustion engines. Airbreathing jet engines typically feature a Axial compressor, rotating air compressor powered by a turbine, with the leftover power providing thrust through the propelling nozzle—this process is known as the Brayton cycle, Brayton thermodynamic cycle. Jet aircraft use such engines for long-distance travel. Early jet aircraft used turbojet engines that were relatively inefficient for subsonic flight. Most modern subsonic jet aircraft use more complex High-bypass turbofan, high-bypass turbofan engines. They give higher speed and greater fuel eff ...

Radar
Radar is a detection system that uses radio waves to determine the distance (''ranging''), angle, and radial velocity of objects relative to the site. It can be used to detect aircraft, ships, spacecraft, guided missiles, motor vehicles, weather formations, and terrain. A radar system consists of a transmitter producing electromagnetic waves in the radio or microwaves domain, a transmitting antenna, a receiving antenna (often the same antenna is used for transmitting and receiving) and a receiver and processor to determine properties of the objects. Radio waves (pulsed or continuous) from the transmitter reflect off the objects and return to the receiver, giving information about the objects' locations and speeds. Radar was developed secretly for military use by several countries in the period before and during World War II. A key development was the cavity magnetron in the United Kingdom, which allowed the creation of relatively small systems with sub-meter resolution. Th ...

Nuclear Power
Nuclear power is the use of nuclear reactions to produce electricity. Nuclear power can be obtained from nuclear fission, nuclear decay and nuclear fusion reactions. Presently, the vast majority of electricity from nuclear power is produced by nuclear ''fission'' of uranium and plutonium in nuclear power plants. Nuclear ''decay'' processes are used in niche applications such as radioisotope thermoelectric generators in some space probes such as ''Voyager 2''. Generating electricity from fusion power, ''fusion'' power remains the focus of international research. Most nuclear power plants use thermal reactors with enriched uranium in a Nuclear fuel cycle#Once-through nuclear fuel cycle, once-through fuel cycle. Fuel is removed when the percentage of neutron poison, neutron absorbing atoms becomes so large that a nuclear chain reaction, chain reaction can no longer be sustained, typically three years. It is then cooled for several years in on-site spent fuel pools before being tr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Insecticide
Insecticides are substances used to kill insects. They include ovicides and larvicides used against insect eggs and larvae, respectively. Insecticides are used in agriculture, medicine, industry and by consumers. Insecticides are claimed to be a major factor behind the increase in the 20th-century's agricultural productivity. Nearly all insecticides have the potential to significantly alter ecosystems; many are toxic to humans and/or animals; some become concentrated as they spread along the food chain. Insecticides can be classified into two major groups: systemic insecticides, which have residual or long term activity; and contact insecticides, which have no residual activity. The mode of action describes how the pesticide kills or inactivates a pest. It provides another way of classifying insecticides. Mode of action can be important in understanding whether an insecticide will be toxic to unrelated species, such as fish, birds and mammals. Insecticides may be repellent ...

Fritz Strassmann
Friedrich Wilhelm Strassmann (; 22 February 1902 – 22 April 1980) was a German chemist who, with Otto Hahn in December 1938, identified the element barium as a product of the bombardment of uranium with neutrons. Their observation was the key piece of evidence necessary to identify the previously unknown phenomenon of nuclear fission, as was subsequently recognized and published by Lise Meitner and Otto Frisch. Personal life and education Strassman was born in Boppard, Germany, to Richard Strassman and Julie Strassmann (née Bernsmann). He was the youngest of nine children. Growing up in Düsseldorf, he developed an interest in chemistry at a young age and conducted chemistry experiments in his parents' home. His family was of modest means, and his father died at a young age, worsening the family's financial situation. Financial considerations limited Strassmann's initial choices of where to pursue his higher education and what subjects they should be. Strassmann began his ...

Otto Hahn
Otto Hahn (; 8 March 1879 – 28 July 1968) was a German chemist who was a pioneer in the fields of radioactivity and radiochemistry. He is referred to as the father of nuclear chemistry and father of nuclear fission. Hahn and Lise Meitner discovered radioactive isotopes of radium, thorium, protactinium and uranium. He also discovered the phenomena of atomic recoil and nuclear isomerism, and pioneered rubidium–strontium dating. In 1938, Hahn, Lise Meitner and Fritz Strassmann discovered nuclear fission, for which Hahn received the 1944 Nobel Prize for Chemistry. Nuclear fission was the basis for nuclear reactors and nuclear weapons. A graduate of the University of Marburg, Hahn studied under Sir William Ramsay at University College London and at McGill University in Montreal under Ernest Rutherford, where he discovered several new radioactive isotopes. He returned to Germany in 1906; Emil Fischer placed a former woodworking shop in the basement of the Chemical Institute ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Olympia, Greece
Olympia ( el, label=Modern Greek, Ολυμπία ; grc, Ὀλυμπία ), officially Archaia Olympia ( el, label=Modern Greek, Αρχαία Ολυμπία; grc, Ἀρχαία Ὀλυμπία, links=no; "Ancient Olympia"), is a small town in Elis on the Peloponnese peninsula in Greece, famous for the nearby archaeological site of the same name. This site was a major Panhellenic religious sanctuary of ancient Greece, where the ancient Olympic Games were held every four years throughout Classical antiquity, from the 8th century BC to the 4th century AD. They were restored on a global basis in 1894 in honor of the ideal of peaceful international contention for excellence. The sacred precinct, named the Altis, was primarily dedicated to Zeus, although other gods were worshipped there. The games conducted in his name drew visitors from all over the Greek world as one of a group of such "Panhellenic" centres, which helped to build the identity of the ancient Greeks as a nation.

Peenemünde Army Research Center
The Peenemünde Army Research Center (german: Heeresversuchsanstalt Peenemünde, HVP) was founded in 1937 as one of five military proving grounds under the German Army Weapons Office (''Heereswaffenamt''). Several German guided missiles and rockets of World War II were developed by the HVP, including the V-2 rocket. The works were attacked by the British in Operation Crossbow from August 1943, before falling to the Soviets in May 1945. History On April 2, 1936, the aviation ministry paid 750,000 reichsmarks to the town of Wolgast for the whole Northern peninsula of the Baltic island of Usedom. By the middle of 1938, the Army facility had been separated from the Luftwaffe facility and was nearly complete, with personnel moved from Kummersdorf. The Army Research Center (''Peenemünde Ost'') consisted of ''Werk Ost'' and ''Werk Süd'', while ''Werk West'' (Peenemünde West) was the Luftwaffe Test Site (), one of the four test and research facilities of the Luftwaffe, with i ...
