HOW FAT MAN WORKS ? | Nuclear Bomb ON Nagasaki | WORLD'S BIGGEST NUCLEAR BOMB | Learn from the base.

Summary

On August 6, 1945, the U.S. dropped 'Little Boy' on Hiroshima, followed by 'Fat Man' on Nagasaki three days later. Fat Man, more efficient than Little Boy, used 6.4 kg of plutonium to create a 21 kiloton explosion. Developed at the Manhattan Project's Los Alamos lab under Robert Oppenheimer, the bomb was 128 inches long and weighed 10,300 lbs. It detonated at 1,600 ft, killing approximately 40,000 people and causing extensive damage through blast, fire, and radiation.

Takeaways

• ⏱️ On August 6, 1945, the United States dropped the 'Little Boy' atomic bomb on Hiroshima, Japan.
• 💥 Three days later, on August 9, 1945, the U.S. dropped the 'Fat Man' atomic bomb on Nagasaki, Japan.
• 🔬 'Fat Man' was more efficient than 'Little Boy', producing a larger blast with less material.
• 🔬 'Little Boy' contained 64 kg of enriched uranium, while 'Fat Man' used only 6.4 kg of plutonium.
• 👨‍🔬 The Manhattan Project, led by Robert Oppenheimer, developed both atomic bombs at the Los Alamos laboratory.
• 🏗️ 'Fat Man' measured 128 inches long and 60 inches in diameter, weighing approximately 10,300 pounds.
• ⚔️ The plutonium core of 'Fat Man' was surrounded by explosives configured in a highly specialized shaped charge.
• 🎚️ The bomb used 32 Bridge wire detonators and 24-volt batteries to ensure simultaneous detonation.
• 🚁 The Boeing B-29 Superfortress aircraft dropped 'Fat Man' over Nagasaki due to obscured primary target.
• 🌋 The explosion resulted in approximately 40,000 deaths and devastated a 3 square mile radius.
• ☢️ The bomb's effects included blast, fire, and radiation, with gamma radiation posing the most significant long-term health risks.

Q & A

On what date was the atomic bomb 'Little Boy' dropped on Hiroshima?

The atomic bomb 'Little Boy' was dropped on Hiroshima on August 6th, 1945.

What was the codename of the second atomic bomb dropped by the United States during World War II?

The codename of the second atomic bomb dropped by the United States was 'Fat Man'.

How much more efficient was the 'Fat Man' bomb compared to 'Little Boy' in terms of yield-to-weight ratio?

The 'Fat Man' bomb was more efficient than 'Little Boy' as it produced a 21 kiloton blast with only 6.4 kg of plutonium, whereas 'Little Boy' produced a 15 kiloton blast with 64 kg of enriched uranium.

Who was the director of the Los Alamos laboratory during the Manhattan Project?

Robert Oppenheimer was the director of the Los Alamos laboratory during the Manhattan Project.

What was the physical size and weight of the 'Fat Man' bomb?

The 'Fat Man' bomb was 128 inches long and 60 inches in diameter, weighing approximately 10,300 pounds.

What was the primary target for the 'Fat Man' bomb before it was dropped on Nagasaki?

The primary target for the 'Fat Man' bomb was the city of Kokura, but due to thick clouds and drifting smoke, the target was shifted to Nagasaki.

What was the detonation altitude of the 'Fat Man' bomb over Nagasaki?

The 'Fat Man' bomb reached a detonation altitude of about 1,600 feet over Nagasaki.

What was the role of the plutonium sphere in the 'Fat Man' bomb?

The plutonium sphere in the 'Fat Man' bomb was responsible for the tremendous explosion, as it was compressed by the shock wave from the explosives, initiating the nuclear chain reaction.

What were the three main effects of the 'Fat Man' bomb's explosion on Nagasaki?

The three main effects of the 'Fat Man' bomb's explosion on Nagasaki were blast, fire, and radiation.

How did the 'Fat Man' bomb's detonation result in the vaporization of some people instantly?

The thermal heat from the explosion, known as the fireball, was so intense that it vaporized some people instantly within the epicenter.

What were the types of radiation released by the 'Fat Man' bomb, and how did they affect people?

The 'Fat Man' bomb released alpha, beta, and gamma radiation. Alpha radiation was less harmful and could be blocked by clothing, beta radiation could penetrate the skin causing burns, and gamma radiation was the most dangerous, penetrating the human body and causing long-term health effects such as cancer and gene mutation.
