What German scientist developed the atomic bomb?

Otto HahnOrigins.

The discovery of nuclear fission by German chemists Otto Hahn and Fritz Strassmann in 1938, and its theoretical explanation by Lise Meitner and Otto Frisch, made the development of an atomic bomb a theoretical possibility..

Why did Japan attack us?

The Japanese intended the attack as a preventive action to keep the United States Pacific Fleet from interfering with its planned military actions in Southeast Asia against overseas territories of the United Kingdom, the Netherlands, and the United States.

What happens if you detonate a nuke in space?

If a nuclear weapon is exploded in a vacuum-i. e., in space-the complexion of weapon effects changes drastically: First, in the absence of an atmosphere, blast disappears completely. … There is no longer any air for the blast wave to heat and much higher frequency radiation is emitted from the weapon itself.

How does Oppenheimer feel after the use of the first atomic bomb?

Witnesses to the first result of that work, the Trinity test, reported that Oppenheimer’s reaction during the test was simply that of relief and satisfaction, and that he exclaimed: “It worked!” But only 11 days after the bombing of Hiroshima, on August 17, 1945, he expressed in writing to the US government his desire …

Who regretted the atomic bomb?

Albert EinsteinFearful that the Germans would beat WWII Allies to a nuclear weapon, physicist Albert Einstein wrote to FDR, urgently pushing America’s A-bomb development. But after the devastation of Hiroshima and Nagasaki, he and many scientists on the project publicly expressed deep regret.

Was the atomic bomb necessary to end ww2?

“No. And it wasn’t necessary either. Militarily Japan was finished (as the Soviet invasion of Manchuria that August showed). Further blockade and urban destruction would have produced a surrender in August or September at the latest, without the need for the costly anticipated invasion or the atomic bomb.

Did Einstein regret bomb?

Einstein regretted the letter. In a 1947 Newsweek article headlined “The Man Who Started It All,” he was quoted as saying, “Had I known that the Germans would not succeed in producing an atomic bomb, I would never have lifted a finger.”

Who made first nuclear bomb in World?

Robert OppenheimerRobert Oppenheimer, “father of the atomic bomb.” On July 16, 1945, in a remote desert location near Alamogordo, New Mexico, the first atomic bomb was successfully detonated—the Trinity Test. It created an enormous mushroom cloud some 40,000 feet high and ushered in the Atomic Age.

Are hydrogen bombs real?

For this reason, thermonuclear weapons are often colloquially called hydrogen bombs or H-bombs. … In modern weapons fueled by lithium deuteride, the fissioning plutonium spark plug also emits free neutrons which collide with lithium nuclei and supply the tritium component of the thermonuclear fuel.

Why did Robert Oppenheimer create the atomic bomb?

Following the 1939 invasion of Poland by Nazi Germany, Oppenheimer was selected to administer a laboratory to carry out the Manhattan Project, a U.S. Army experiment aimed at harnessing atomic energy for military purposes. He led the scientific end of the Manhattan Project in Los Alamos, New Mexico, beginning in 1942.

How is a plutonium bomb different from a uranium bomb?

The destructive power of the Plutonium bomb in war was first demonstrated on Nagasaki. The bomb consisted of 10 kg of Pu-239 at its core. Unlike Uranium, virtually any combination of Plutonium isotopes can be used to make a new clear weapon. … Weapons Grade Plutonium is said to contain greater than 93% Pu-239.

Is Nagasaki still radioactive?

Among some there is the unfounded fear that Hiroshima and Nagasaki are still radioactive; in reality, this is not true. Following a nuclear explosion, there are two forms of residual radioactivity. … In fact, nearly all the induced radioactivity decayed within a few days of the explosions.

What did Oppenheimer say about the atomic bomb?

Did Oppenheimer make the atomic bomb?

J. Robert Oppenheimer (1904-1967) was an American theoretical physicist. During the Manhattan Project, Oppenheimer was director of the Los Alamos Laboratory and responsible for the research and design of an atomic bomb. He is often known as the “father of the atomic bomb.”

Do scientists regret making the atomic bomb?

Robert Oppenheimer — The atomic bomb. … He believed Germany was attempting to create an atomic bomb to use against the Allies in World War II, and he signed a letter to President Franklin Roosevelt encouraging him to support U.S. research into producing one as well. Years later, he regretted it.

Why did US bomb Hiroshima and not Tokyo?

The U.S. likely did not target Tokyo for the atomic bomb strikes as it was the seat of the Emperor and the location of much of the high ranking military officers. … The U.S. decided to drop the bombs onto military industrial targets and centers that had significant military utility such as ports and airfields.

Why did we bomb Japan twice?

The explicit reason was to swiftly end the war with Japan. … Ever since America dropped a second atomic bomb on Nagasaki, Japan on August 9, 1945, the question has persisted: Was that magnitude of death and destruction really needed to end World War II? American leadership apparently thought so.

What special ingredient is needed to build an atomic bomb?

The raw material: uranium The key ingredient in a nuclear bomb is enriched uranium — or plutonium, which can be obtained through the combustion of uranium. Uranium is a relatively common mineral, found both in the ground and under the sea. Some 20 countries operate uranium mines.
