Bulletin of the Atomic ScientistsThe Bulletin of the Atomic Scientists is a nonprofit organization concerning science and global security issues resulting from accelerating technological advances that have negative consequences for humanity. The Bulletin publishes content at both a free-access website and a bi-monthly, nontechnical academic journal. The organization has been publishing continuously since 1945, when it was founded by Albert Einstein and former Manhattan Project scientists as the Bulletin of the Atomic Scientists of Chicago immediately following the atomic bombings of Hiroshima and Nagasaki.
Japanese nuclear weapons programThe Japanese program to develop nuclear weapons was conducted during World War II. Like the German nuclear weapons program, it suffered from an array of problems, and was ultimately unable to progress beyond the laboratory stage before the atomic bombings of Hiroshima and Nagasaki and the Japanese surrender in August 1945. Today, Japan's nuclear energy infrastructure makes it capable of constructing nuclear weapons at will.
Debate over the atomic bombings of Hiroshima and NagasakiSubstantial debate exists over the ethical, legal, and military aspects of the atomic bombings of Hiroshima and Nagasaki on 6 August and 9 August 1945 at the close of World War II (1939–45). On 26 July 1945, United States President Harry S. Truman, British Prime Minister Winston Churchill and President of China Chiang Kai-shek issued the Potsdam Declaration, which outlined the terms of surrender for the Empire of Japan as agreed upon at the Potsdam Conference.
UrakamiUrakami was an area in the northern part of the city of Nagasaki, Japan. In 1614, by the orders of shōgun leader Tokugawa Ieyasu, Christianity was banned in Japan in order to suppress European influence and to prevent the undermining of the Japanese government. Most Japanese Christians who openly spoke about their religion were open to prosecution and subject to extreme harsh treatment, such as torture or crucifixion. As a result, Urakami became the stronghold for oppressed believers who steadfastly adhered to their religion in secret.
German nuclear weapons programThe names Uranverein () or Uranprojekt () came to be applied in Nazi Germany to the undertakings of research in nuclear technology, including nuclear weapons and nuclear reactors, before and during World War II. The first effort started in April 1939, just months after the discovery of nuclear fission in Berlin in December 1938, but ended only few months later, shortly ahead of the September 1939 German invasion of Poland, for which many notable German physicists were drafted into the Wehrmacht.
Area bombardmentIn military aviation, area bombardment (or area bombing) is a type of aerial bombardment in which bombs are dropped over the general area of a target. The term "area bombing" came into prominence during World War II. Area bombing is a form of strategic bombing. It can serve several intertwined purposes: to disrupt the production of military materiel, to disrupt lines of communications, to divert the enemy's industrial and military resources from the primary battlefield to air defence and infrastructure repair, and to demoralise the enemy's population (See terror bombing).
Precision bombingPrecision bombing is the attempted aerial bombing of a target with some degree of accuracy, with the aim of maximising target damage or limiting collateral damage. Its strategic counterpart is carpet bombing. An example would be destroying a single building in a built up area causing minimal damage to the surroundings. Precision bombing was initially tried by both the Allied and Central Powers during World War I, however it was found to be ineffective because the technology did not allow for sufficient accuracy.
FirebombingFirebombing is a bombing technique designed to damage a target, generally an urban area, through the use of fire, caused by incendiary devices, rather than from the blast effect of large bombs. In popular usage, any act in which an incendiary device is used to initiate a fire is often described as a "firebombing". Although simple incendiary bombs have been used to destroy buildings since the start of gunpowder warfare, World War I saw the first use of strategic bombing from the air to damage the morale and economy of the enemy, such as the German Zeppelin air raids conducted on London.
Thermonuclear weaponA thermonuclear weapon, fusion weapon or hydrogen bomb (H bomb) is a second-generation nuclear weapon design. Its greater sophistication affords it vastly greater destructive power than first-generation nuclear bombs, a more compact size, a lower mass, or a combination of these benefits. Characteristics of nuclear fusion reactions make possible the use of non-fissile depleted uranium as the weapon's main fuel, thus allowing more efficient use of scarce fissile material such as uranium-235 () or plutonium-239 ().
TinianTinian (ˈtɪniən or ˌtiːniˈɑːn; old Japanese name: 天仁安島, Tenian-shima) is one of the three principal islands of the Commonwealth of the Northern Mariana Islands. Together with uninhabited neighboring Aguiguan, it forms Tinian Municipality, one of the four constituent municipalities of the Northern Marianas. Tinian's largest village is San Jose. The Mariana Islands, of which Tinian is one, were the first islands settled by humans in Remote Oceania.
