Who is considered the father of the atomic bomb?
Oppenheimer is considered the father of the atomic bomb – and in the McCarthy era a moralist, a leftist and a security risk. Kai Bird and Martin J. Sherwin have now submitted a biography about him. Julius Robert Oppenheimer was born into a wealthy family in 1904.

The test had to be postponed by two hours because of a thunderstorm: On July 16, 1945, in the New Mexico desert, a steel ball was waiting to be used on a 30-meter-high metal structure.
Who Invented the Atomic Bomb Wikipedia?
Oppenheimer is best known for his role as scientific director of the Manhattan Project during World War II. Located in the secretive Los Alamos National Laboratory in New Mexico, this project aimed to develop the first nuclear weapons.
Who built the 1 atomic bomb?
The atomic bomb was first developed by the United States in the Manhattan Project. On July 16, 1945, the first nuclear weapon test with a nuclear weapon explosion took place under the project name Trinity (English ‘Trinity’).
How hot is the atomic bomb?
Due to the enormous energy density, the temperatures inside the bomb rise rapidly to between 60 and 100 million degrees Celsius. This corresponds to about 10,000 to 20,000 times the surface temperature of our sun (about 5500 degrees Celsius).
What was the name of the first atomic bomb?
Little Boy was the codename of the first atomic bomb used in a war, dropped by the USAAF B-29 Enola Gay bomber on August 6, 1945 over the Japanese city of Hiroshima, hence the name Hiroshima bomb.

What is the radius of an atomic bomb?
The mushroom cloud of an atomic bomb is 13 kilometers high and has a radius of 30 kilometers.
What is the explosive power of an atomic bomb?
Hydrogen bombs can produce nuclear explosions hundreds to thousands of times stronger than conventional nuclear bombs. The explosive power of atomic bombs is often measured in kilotons or one thousand tons of TNT. Hydrogen bombs, on the other hand, are generally measured in megatons, or one million tons of TNT.
What is the range of an atomic bomb?
1 kg of TNT devastates a radius of approx. 5 m with a pressure difference of more than 280 mbar. The Little Boy atomic bomb dropped on Hiroshima in 1945 had a yield of 13,000 tons of TNT. The largest man-made explosion, caused by the Tsar bomb, had a yield of 57 million tons of TNT.
What does an atomic bomb do?
The first effect of an atomic bomb is an intense flash of light. The temperatures rise so much that everything in a certain area is vaporized. The electromagnetic waves emitted by the mushroom cloud as a result of its high temperature are called thermal radiation.
How did Pakistan get nuclear weapons?
Like its neighbor and arch-rival India, Pakistan is a de facto nuclear power and has not signed the NPT. However, Pakistan’s original goal of having the atomic bomb by 1976 could not be met. The first public atomic bomb test took place in 1998.
How much TNT does an atomic bomb have?
Nuclear Weapons: The atomic bomb dropped by the United States on Hiroshima in 1945 had a yield of about 13 kilotons of TNT.
