Operation Grapple was a set of four British nuclear weapons test series of early atomic bombs and hydrogen bombs carried out in and at Malden Island and Kiritimati Christmas Island in the Gilbert and Ellice Islands in the Pacific Ocean modern Kiribati as part of the British hydrogen bomb programme. Nine nuclear explosions were initiated, culminating in the United Kingdom becoming the third recognised possessor of thermonuclear weapons and the restoration of the nuclear Special Relationship with the United States with the US-UK Mutual Defence Agreement. Many of Britain’s top scientists participated in the British contribution to the Manhattan Project. After the war, fearing that Britain would lose its great power status, the British government resumed the atomic bomb development effort, now codenamed High Explosive Research. The successful test of an atomic bomb in Operation Hurricane in October represented an extraordinary scientific and technological achievement, but Britain was still several years behind the United States in nuclear weapons technology. In July , the Cabinet decided to develop the hydrogen bomb. The first test series consisted of three tests in May and June Despite its failure, the test was hailed as a successful thermonuclear explosion, and the government did not confirm or deny reports that the UK had become a third thermonuclear power. The second test was Grapple 2, of Orange Herald. It was the largest ever achieved by a single stage device.

A mushroom cloud hangs over Hiroshima on 6 August An estimated 90, to , people died that day or soon after; many others developed cancer later. Iida was 3 years old in August The blast crumpled the house. His injuries left him bedridden for years, and he has suffered debilitating illnesses ever since. Childhood anemia caused him to collapse at school.
Yet Iida has survived. Thousands of others died prematurely over the years because of radiation-induced cancer, a tally that is still growing.
How can you tell if a painting is a modern forgery? Midth-century nuclear bomb tests may hold a clue. For years, scientists have been refining techniques to determine the age of a painting using radiocarbon dating and the lingering effects of the tests. Now, a team of researchers has dated one such artwork using a paint chip the size of a poppy seed, according to a study published on Monday in The Proceedings of the National Academy of Sciences.

President Harry S. Truman publicly announces his decision to support the development of the hydrogen bomb, a weapon theorized to be hundreds of times more powerful than the atomic bombs dropped on Japan during World War II. Five months earlier, the United States had lost its nuclear supremacy when the Soviet Union successfully detonated an atomic bomb at their test site in Kazakhstan. Then, several weeks after that, British and U. The The incredible explosive force of Mike was also apparent from the sheer magnitude of its mushroom cloud—within 90 seconds the mushroom cloud climbed to 57, feet and entered the stratosphere.
One minute later, it reached , feet, eventually stabilizing at a ceiling of , feet. Half an hour after the test, the mushroom stretched 60 miles across, with the base of the head joining the stem at 45, feet. Three years later, on November 22, , the Soviet Union detonated its first hydrogen bomb on the same principle of radiation implosion.

Five filmmaking teams, all with a director under 35 years, have been given the opportunity to create a prime time half hour film that not only develops their long form filmmaking skills but also fires an opening shot in to the national conversation about Australia today. From the moral minefield of modern reproductive science to online hacktivism, these films share the voice of a generation tackling the issues that are important to them, and that have consequences for all of us.
What they collectively demonstrate is that while today’s younger generations may be disengaged from traditional party politics they are not disengaged from the issues that matter.

Why the US dropped an atomic bomb on Hiroshima

The bomb fell just over 29, feet from the plane and detonated 1, feet above Shima Hospital, an active medical center with a history dating back to the 18th Century. Between four and five square miles of buildings were leveled in the blast generated by just pounds of highly enriched uranium.
On this date 74 years ago, the US dropped the first of two atomic bombs on the Japanese city of Hiroshima, killing more than people.
Nuclear weapons possess enormous destructive power from nuclear fission or combined fission and fusion reactions. Building on scientific breakthroughs made during the s, the United States, Canada, free France and Great Britain collaborated during World War II , in what was called the Manhattan Project , to build a fission weapon, also known as an atomic bomb.
The Soviet Union started development shortly after with their own atomic bomb project , and not long after, both countries were developing even more powerful fusion weapons known as hydrogen bombs. Britain and France built their own systems in the s, and the list of states with nuclear weapons has gradually grown larger in the decades since. In the first decades of the 20th century, physics was revolutionised with developments in the understanding of the nature of atoms.
In , Pierre and Marie Curie discovered that pitchblende , an ore of uranium , contained a substance—which they named radium —that emitted large amounts of radioactivity. Ernest Rutherford and Frederick Soddy identified that atoms were breaking down and turning into different elements. Hopes were raised among scientists and laymen that the elements around us could contain tremendous amounts of unseen energy, waiting to be harnessed.

Home Explore the BBC. Three weeks after the Bikini bomb it emerged that a Japanese fishing boat, called Lucky Dragon, was within 80 miles km of the test zone at the time. Its 23 crew were severely affected by radiation sickness. They were among people accidentally exposed to radiation because the explosion and fall-out had been far greater than expected. But they were evacuated four years later when new tests showed high levels of residual radioactivity in the region.
Twenty-three nuclear tests were carried out at Bikini between and
North Korea said it set off a hydrogen bomb Sunday in its sixth nuclear nuclear test to date, a big step toward its goal of developing nuclear weapons Kim signed off on the plan, but is watching the moves by the U.S. before.

TOKYO — North Korea announced it detonated a thermonuclear device Sunday in its sixth and most powerful nuclear test to date, a big step toward its goal of developing nuclear weapons capable of striking anywhere in the U. The North called it a “perfect success” while its neighbors condemned the blast immediately.
Though the precise strength of the explosion has yet to be determined, South Korea’s weather agency said the artificial earthquake it caused was five to six times stronger than tremors generated by its previous tests. It reportedly shook buildings in China and in Russia.
