πŸ”— Eric Roberts (Spy)

πŸ”— Biography πŸ”— Espionage πŸ”— Germany πŸ”— Military history πŸ”— Military history/Military biography πŸ”— Biography/military biography πŸ”— United Kingdom πŸ”— Military history/World War II

Eric Arthur Roberts (18 June 1907 – 17 or 18 December 1972) was an MI5 agent during the Second World War under the alias Jack King. By posing as a Gestapo agent and infiltrating fascist groups in the UK, Roberts was able to prevent secret information finding its way to Germany. Roberts continued to work for the security services after the war, particularly in Vienna, but it was a time of great anxiety in the services because of the suspicions surrounding double agents such as the Cambridge spy ring.

Roberts never felt completely accepted by MI5 because of his social background and a desk role did not suit him as well as his wartime role had. He is the subject of the biography Agent Jack (2018) by Robert Hutton, and his adventures were the inspiration for the novel Our Friends In Berlin by Anthony Quinn and for a major character in the novel Transcription by Kate Atkinson.

πŸ”— Basil Zaharoff

πŸ”— Biography πŸ”— Military history πŸ”— Military history/Military biography πŸ”— Military history/World War II

Sir Basil Zaharoff, GCB, GBE, born Vasileios Zacharias (Greek: ΒασίλΡιος Zαχαρίας Ζαχάρωφ; October 6, 1849 – November 27, 1936), was a Greek arms dealer and industrialist. One of the richest men in the world during his lifetime, Zaharoff was described as a "merchant of death" and "mystery man of Europe". His success was forged through his cunning, often aggressive and sharp, business tactics. These included the sale of arms to opposing sides in conflicts, sometimes delivering fake or faulty machinery and skilfully using the press to attack business rivals.

Zaharoff maintained close contacts with many powerful political leaders, including British Prime Minister David Lloyd George, Greek Prime Minister Eleftherios Venizelos and Ottoman Sultan Abdul Hamid II; he served as a primary inspiration for Ian Fleming's fictional James Bond villain Ernst Stavro Blofeld.

πŸ”— FOGBANK

FOGBANK is a code name given to a material used in nuclear weapons such as the W76, W78 and W80.

FOGBANK's precise nature is classified; in the words of former Oak Ridge general manager Dennis Ruddy, "The material is classified. Its composition is classified. Its use in the weapon is classified, and the process itself is classified." Department of Energy Nuclear Explosive Safety documents simply describe it as a material "used in nuclear weapons and nuclear explosives" along with lithium hydride (LiH) and lithium deuteride (LiD), beryllium (Be), uranium hydride (UH3), and plutonium hydride.

However National Nuclear Security Administration (NNSA) Administrator Tom D'Agostino disclosed the role of FOGBANK in the weapon: "There's another material in theβ€”it's called interstage material, also known as fog bank", and arms experts believe that FOGBANK is an aerogel material which acts as an interstage material in a nuclear warhead; i.e., a material designed to become a superheated plasma following the detonation of the weapon's fission stage, the plasma then triggering the fusion-stage detonation.

πŸ”— Polybolos

πŸ”— Military history πŸ”— Military history/Military science, technology, and theory πŸ”— Military history/Weaponry πŸ”— Classical Greece and Rome πŸ”— Military history/Classical warfare

Polybolos, meaning "multi thrower" in Greek, was an ancient Greek repeating ballista reputedly invented by Dionysius of Alexandria, a 3rd-century BC Greek engineer at the Rhodes arsenal, and used in antiquity.

Philo of Byzantium encountered and described a weapon similar to the polybolos, a catapult that like a modern machine gun could fire again and again without a need to reload. Philo left a detailed description of the gears that powered its chain drive, the oldest known application of such a mechanism, and that placed bolt after bolt into its firing slot.

The War Powers Resolution (also known as the War Powers Resolution of 1973 or the War Powers Act) (50 U.S.C. ch. 33) is a federal law intended to check the U.S. president's power to commit the United States to an armed conflict without the consent of the U.S. Congress. The resolution was adopted in the form of a United States congressional joint resolution. It provides that the president can send the U.S. Armed Forces into action abroad only by declaration of war by Congress, "statutory authorization", or in case of "a national emergency created by attack upon the United States, its territories or possessions, or its armed forces".

The bill was introduced by Clement Zablocki, a Democratic congressman representing Wisconsin's 4th district. The bill had bipartisan support and was co-sponsored by a number of U.S. military veterans. The War Powers Resolution requires the president to notify Congress within 48 hours of committing armed forces to military action and forbids armed forces from remaining for more than 60 days, with a further 30-day withdrawal period, without congressional authorization for use of military force (AUMF) or a declaration of war by the United States. The resolution was passed by two-thirds each of the House and Senate, overriding the veto of President Richard Nixon.

It has been alleged that the War Powers Resolution has been violated in the past. However, Congress has disapproved all such incidents, and no allegations have resulted in successful legal actions taken against a president.

πŸ”— Communication with Submarines

πŸ”— Technology πŸ”— Military history πŸ”— Military history/Military science, technology, and theory πŸ”— Military history/Maritime warfare

Communication with submarines is a field within military communications that presents technical challenges and requires specialized technology. Because radio waves do not travel well through good electrical conductors like salt water, submerged submarines are cut off from radio communication with their command authorities at ordinary radio frequencies. Submarines can surface and raise an antenna above the sea level, then use ordinary radio transmissions, however this makes them vulnerable to detection by anti-submarine warfare forces. Early submarines during World War II mostly traveled on the surface because of their limited underwater speed and endurance; they dove mainly to evade immediate threats. During the Cold War, however, nuclear-powered submarines were developed that could stay submerged for months. Transmitting messages to these submarines is an active area of research. Very low frequency (VLF) radio waves can penetrate seawater a few hundred feet, and many navies use powerful VLF transmitters for submarine communications. A few nations have built transmitters which use extremely low frequency (ELF) radio waves, which can penetrate seawater to reach submarines at operating depths, but these require huge antennas. Other techniques that have been used include sonar and blue lasers.

πŸ”— My Trial as a War Criminal (By Leo Szilard, Inventor of Nuclear Chain Reaction)

πŸ”— Military history πŸ”— Military history/Military biography

"My Trial as a War Criminal" is a 1949 short story by atomic physicist Leo Szilard. Szilard had played a leading role in the Manhattan Project, and in the story he imagines the kind of show trial he might have had if he had been prosecuted in a manner similar to the Nuremberg Trials. Szilard earlier drafted the letter Albert Einstein signed, to Franklin Roosevelt, suggesting the US develop the military uses of nuclear power, and later the petition unsuccessfully advocating against the use of nuclear weapons.

The Sovereign Military Order of Malta (SMOM), officially the Sovereign Military Hospitaller Order of Saint John of Jerusalem, of Rhodes and of Malta (Italian: Sovrano Militare Ordine Ospedaliero di San Giovanni di Gerusalemme di Rodi e di Malta; Latin: Supremus Militaris Ordo Hospitalarius Sancti Ioannis Hierosolymitani Rhodiensis et Melitensis), commonly known as the Order of Malta, Malta Order or Knights of Malta, is a Catholic lay religious order, traditionally of military, chivalric and noble nature. Though it possesses no territory, the order is a sovereign entity of international law and maintains diplomatic relations with many countries.

SMOM claims continuity with the Knights Hospitaller, a chivalric order that was founded c. 1099 by the Blessed Gerard in the Kingdom of Jerusalem. The order is led by an elected Prince and Grand Master. Its motto is Tuitio fidei et obsequium pauperum ('defence of the faith and assistance to the poor'). The order venerates the Virgin Mary as its patroness, under the title of Our Lady of Philermos. Its modern-day role is largely focused on providing humanitarian assistance and assisting with international humanitarian relations, for which purpose it has had permanent observer status at the United Nations General Assembly since 1994.

The Jewel Voice Broadcast (ηŽ‰ιŸ³ζ”Ύι€, Gyokuon-hōsō) was the radio broadcast in which Japanese Emperor Hirohito (Emperor Shōwa ζ˜­ε’Œε€©ηš‡ Shōwa-tennō) read out the Imperial Rescript on the Termination of the Greater East Asia War (ε€§ζ±δΊœζˆ¦δΊ‰η΅‚η΅γƒŽθ©”ζ›Έ, Daitōa-sensō-shΕ«ketsu-no-shōsho), announcing to the Japanese people that the Japanese Government had accepted the Potsdam Declaration demanding the unconditional surrender of the Japanese military at the end of World WarΒ II. This speech was broadcast at noon Japan Standard Time on August 15, 1945.

The speech was probably the first time that an Emperor of Japan had spoken (albeit via a phonograph record) to the common people. It was delivered in the formal, Classical Japanese that few ordinary people could easily understand. It made no direct reference to a surrender of Japan, instead stating that the government had been instructed to accept the terms of the Potsdam Declaration fully. This created confusion in the minds of many listeners who were not sure whether Japan had surrendered. The poor audio quality of the radio broadcast, as well as the formal courtly language in which the speech was composed, worsened the confusion. A digitally remastered version of the broadcast was released on 30 June 2015.

The Blohm & Voss BV 141 was a World War II German tactical reconnaissance aircraft. It is notable for its uncommon structural asymmetry. Although the Blohm & Voss BV 141 performed well, it was never ordered into full-scale production, for reasons that included the unavailability of the preferred engine and competition from another tactical reconnaissance aircraft, the Focke-Wulf Fw 189.
