Section 1.1: Understanding the Atomic Bomb

To conclude World War II, the United States dropped two atomic bombs on the Japanese cities of Hiroshima and Nagasaki. These bombings resulted in the deaths of hundreds of thousands. How can such devastating power be achieved? Scientists have theorized that a minuscule amount of material can unleash a tremendous amount of energy, a concept famously advocated by Albert Einstein.

It’s a common misconception that Einstein invented the atomic bomb. Rather, he proposed a theory explaining that the decay of a tiny quantity of particles can release vast energy. At that time, Einstein's statements were taken seriously, leading countries like Britain, Germany, and the USA to pursue practical applications of his ideas.

Britain discovered that uranium, a radioactive element, could serve this purpose and shared this knowledge with the United States. Consequently, the USA initiated the Manhattan Project, a costly endeavor aimed at developing a uranium-based bomb. This project involved experts from various fields, including physicists Robert Oppenheimer and Enrico Fermi, who led a team of engineers and MIT scientists.

This group unraveled the process of nuclear fission, where a neutron collides with a uranium nucleus, causing it to split into another neutron and releasing a significant amount of energy in the process. The released neutrons can then collide with additional uranium nuclei, creating a chain reaction.

However, executing this chain reaction is not straightforward. Only a select few countries, including the USA, Britain, Russia, France, Israel, China, North Korea, India, and Pakistan, possess the capability to achieve it. Merely having uranium is insufficient; a supercritical mass is required to sustain the chain reaction.

Section 1.2: The Power of the Hydrogen Bomb

Now, let’s shift our focus to the hydrogen bomb. Unlike the atomic bomb, the hydrogen bomb relies on nuclear fusion. To understand the power of this bomb, it’s crucial to note that, according to Time magazine, a hydrogen bomb is approximately 1,000 times more powerful than an atomic bomb.

Nuclear fusion occurs when two different atoms collide to form a new atom, similar to the process that fuels the sun. The energy released through fusion surpasses that produced by fission.

Fortunately, such bombs have never been deployed against humanity. However, both the United States and Russia conducted tests of hydrogen bombs in the 1950s, maintaining a readiness to use both bomb types.
