This Is How A Nuclear Bomb Works
BE AMAZED・2 minutes read
Nuclear weapons have had a global impact since 1945, starting with Otto Hahn's discovery of nuclear energy and the Manhattan Project leading to the first atomic bombings in Japan, showcasing the devastating power of these weapons and subsequent arms race between major powers. The process of nuclear fusion, utilized in hydrogen bombs, involves compressing atoms at high heat levels, while modern nuclear warfare centers around ballistic missiles carrying hydrogen warheads, with Russia and the USA possessing significant arsenals that could lead to a potential nuclear winter.
Insights
- Nuclear weapons, born from Otto Hahn's discovery of nuclear energy and the Manhattan Project's development, have sparked global fear since 1945, with escalating destructive power showcased by the US and Soviet Union during the Cold War.
- The fusion of small atoms like hydrogen in hydrogen bombs releases immense energy, requiring extreme heat and compression, highlighting the complex science behind these weapons and the potential for catastrophic global consequences in modern nuclear warfare.

Global Fear: History and Power of Nuclear Weapons
- Nuclear weapons have instilled fear globally since their first use in 1945, with the potential for world leaders to initiate nuclear war.
- German scientist Otto Hahn's discovery of nuclear energy in 1938 led to the development of nuclear weapons.
- The Manhattan Project, initiated by US President Franklin D. Roosevelt, aimed to weaponize nuclear energy during World War II.
- The first nuclear bomb test, the "Trinity Test," occurred on July 16, 1945, in New Mexico, with a destructive power of one kiloton.
- The atomic bombing of Hiroshima on August 6, 1945, using the bomb "Little Boy," led to catastrophic destruction and the Japanese surrender.
- Subsequently, the bombing of Nagasaki with the more powerful "Fat Man" bomb resulted in further devastation and over 200,000 casualties.
- The US and Soviet Union escalated nuclear testing during the Cold War, with the US detonating the first hydrogen bomb in 1952, 1,000 times more powerful than the Hiroshima bomb.
- The Soviet Union's "Tsar Bomba" in 1961 was a 57-megaton hydrogen bomb, the largest ever created, showcasing immense destructive capability.
- Nuclear testing by various nations, including the UK, France, and China, led to significant environmental consequences and radioactive fallout.
- The process of nuclear fission, discovered by Otto Hahn, underpins the immense power of nuclear weapons, with nuclear fusion being even more potent and utilized in hydrogen bombs.

Nuclear Fusion: Energy, Bombs, and Warfare
- Nuclear fusion involves fusing small atoms like hydrogen together, releasing a huge amount of energy.
- To overcome the repelling force between atoms and fuse them, compress them into a small space and heat them to at least 180 million degrees Fahrenheit.
- On Earth, nuclear fusion requires high heat due to lack of immense gravitational pressures like at the sun's core.
- Hydrogen bombs use nuclear fission to generate heat for a more powerful fusion reaction.
- "Little Boy" bomb used uranium-235 and a simple design involving two pieces smashing together to initiate a fission reaction.
- "Fat Man" bomb used plutonium-239 with a more complex design involving a plutonium sphere surrounded by uranium and conventional explosives for a symmetrical implosion.
- Both bombs were detonated in the air for maximum destructive potential, using specialized circuitry to trigger the explosion.
- Modern nuclear warfare involves ballistic missiles carrying hydrogen-powered warheads, with Russia possessing the most nukes followed by the USA, and the potential catastrophic effects of a nuclear winter.
