Minox DCC Leica M3 Digital Classic
Minox (pronounced ) is a manufacturer of cameras, known especially for its subminiature camera. The first product to carry the Minox name was a subminiature camera, conceived in 1922, and finally invented and produced in 1936, by Baltic German Walter Zapp. The Latvian factory VEF (''Valsts elektrotehniskā fabrika'') manufactured the camera from 1937 to 1943. After World War II, the camera was redesigned and production resumed in Germany in 1948. Walter Zapp originally envisioned the Minox to be a camera for everyone requiring only little photographic knowledge. Yet in part due to its high manufacturing costs the Minox became more well known as a must-have luxury item. From the start the Minox also gained wide notoriety as a spy camera. Minox branched out into 35 mm film format and 110 film format cameras in 1974 and 1976, respectively. Minox continues to operate today, producing or branding optical and photographic equipment.

Walter Zapp
Walter Zapp ( lv, Valters Caps; – 17 July 2003) was a Baltic German inventor. His greatest creation was the Minox subminiature camera. Biography Zapp was born in Riga, Governorate of Livonia (now Latvia). In 1932, while living in Estonia, he began developing the then subminiature camera by first creating wooden models, which led to the first prototype in 1936. It was introduced to the market in 1938. Minox cameras were made by VEF (Valsts Elektrotehniskā Fabrika) in Latvia. VEF made 17,000 Minox cameras. During the Spring 1941 Resettlement of Baltic Germans, Walter Zapp moved to Germany. From 1941 to 1945, he worked on the development of electron microscopy at AEG in Berlin. After World War II, in 1945, he founded the Minox GmbH in Wetzlar, Germany. The company still exists. In 2001, when he went to Latvia for the last time, he said that he had gone to celebrate his 100th birthday in Latvia. He died aged 97, in Binningen near Basel, Switzerland. Patents ...

SL-1
Stationary Low-Power Reactor Number One, also known as SL-1 or the Argonne Low Power Reactor (ALPR), was a United States Army experimental nuclear reactor in the western United States at the National Reactor Testing Station (NRTS), later the Idaho National Laboratory, west of Idaho Falls, Idaho. It experienced a steam explosion on the night of January 3, 1961, killing all three of its young military operators, and pinning one of them to the ceiling of the facility with a reactor vessel plug. The event is the only reactor accident in U.S. history that resulted in immediate fatalities. The direct cause was the over-withdrawal of the central control rod, responsible for absorbing neutrons in the reactor's core. The accident released about of iodine-131, which was not considered significant due to its location in the remote high desert of eastern Idaho. About of fission products were released into the atmosphere. The facility housing SL-1, located approximately west of Idah ...

Cryptography
Cryptography, or cryptology (from grc, , translit=kryptós "hidden, secret"; and ''graphein'', "to write", or ''-logia'', "study", respectively), is the practice and study of techniques for secure communication in the presence of adversarial behavior. More generally, cryptography is about constructing and analyzing protocols that prevent third parties or the public from reading private messages. Modern cryptography exists at the intersection of the disciplines of mathematics, computer science, information security, electrical engineering, digital signal processing, physics, and others. Core concepts related to information security ( data confidentiality, data integrity, authentication, and non-repudiation) are also central to cryptography. Practical applications of cryptography include electronic commerce, chip-based payment cards, digital currencies, computer passwords, and military communications. Cryptography prior to the modern age was effectively synonymo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

John Anthony Walker
John Anthony Walker Jr. (July 28, 1937 – August 28, 2014) was a United States Navy chief warrant officer and communications specialist convicted of spying for the Soviet Union from 1967 to 1985 and sentenced to life in prison. In late 1985, Walker made a plea bargain with federal prosecutors, which required him to provide full details of his espionage activities and testify against his co-conspirator, former senior chief petty officer Jerry Whitworth. In exchange, prosecutors agreed to a lesser sentence for Walker's son, former Seaman Michael Walker, who was also involved in the spy ring. During his time as a Soviet spy, Walker helped the Soviets decipher more than one million encrypted naval messages, organizing a spy operation that ''The New York Times'' reported in 1987 "is sometimes described as the most damaging Soviet spy ring in history." After Walker's arrest, Caspar Weinberger, President Ronald Reagan's Secretary of Defense, concluded that the Soviet Union mad ...

Axis Powers
The Axis powers, ; it, Potenze dell'Asse ; ja, 枢軸国 ''Sūjikukoku'', group=nb originally called the Rome–Berlin Axis, was a military coalition that initiated World War II and fought against the Allies. Its principal members were Nazi Germany, the Kingdom of Italy, and the Empire of Japan. The Axis were united in their opposition to the Allies, but otherwise lacked comparable coordination and ideological cohesion. The Axis grew out of successive diplomatic efforts by Germany, Italy, and Japan to secure their own specific expansionist interests in the mid-1930s. The first step was the protocol signed by Germany and Italy in October 1936, after which Italian leader Benito Mussolini declared that all other European countries would thereafter rotate on the Rome–Berlin axis, thus creating the term "Axis". The following November saw the ratification of the Anti-Comintern Pact, an anti-communist treaty between Germany and Japan; Italy joined the Pact in 1937, follow ...

Cold War
The Cold War is a term commonly used to refer to a period of geopolitical tension between the United States and the Soviet Union and their respective allies, the Western Bloc and the Eastern Bloc. The term '' cold war'' is used because there was no large-scale fighting directly between the two superpowers, but they each supported major regional conflicts known as proxy wars. The conflict was based around the ideological and geopolitical struggle for global influence by these two superpowers, following their temporary alliance and victory against Nazi Germany and Imperial Japan in 1945. Aside from the nuclear arsenal development and conventional military deployment, the struggle for dominance was expressed via indirect means such as psychological warfare, propaganda campaigns, espionage, far-reaching embargoes, rivalry at sports events, and technological competitions such as the Space Race. The Western Bloc was led by the United States as well as a number of other First W ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
West Germany
West Germany is the colloquial term used to indicate the Federal Republic of Germany (FRG; german: Bundesrepublik Deutschland , BRD) between its formation on 23 May 1949 and the German reunification through the accession of East Germany on 3 October 1990.
