About Bomb

At the 1994 Aviation Exhibition in California, the B-2 Spirit bomber dropped 47 Mark 23 bombs weighing 48230 kilograms (500 pounds).

A bomb is a type of explosive and weapon made of metal. The chemical reaction of internal energy very quickly can cause large vibrational waves to explode and cause extensive damage to life and property. It has been used in the world for centuries. Most bombs store less energy than ordinary fuel. The exception is the atomic bomb.

Bombs are usually filled with containers suitable for storing explosives. It is placed or thrown away according to the design with destructive objects. The word bomb originates from the Greek word bombas which carries the same meaning through the English word boom.

Use Bomb

Often the military targets the enemy's targets. Also, members of the terrorist forces carry out suicide bombings to achieve their objectives. In addition, bombs are used to locate mines as part of peaceful activities.

The high pressure of a bomb blast can cause permanent damage or even death, including internal damage to a person under sudden and intense ambient pressure. In addition, huge holes, debris or vegetation were uprooted in the blast site. Mine explosions under water or over the sea are a common occurrence. [1]


In response to vibrational waves of explosives, mutilation can occur. It also has the ability to throw a victim into the air. In addition, amputation, internal bleeding, and perforation of the eardrum can lead to hearing loss. [2] During a speech at a public meeting in Dhaka on 21 August 2004, the grenade attack killed the present Prime Minister of Bangladesh Sheikh Hasina Alp and her eardrums were severely damaged. The attack killed 19 people, including Awami League leader Ivy Rahman, and injured hundreds more.

Powerful hydrogen bomb

Hydrogen bombs are many times more powerful than atomic bombs. Its devastation is much more terrible. On Wednesday, North Korea announced the successful test of a hydrogen bomb. What is a hydrogen bomb and why did North Korea take such a step?

Huge move for North Korea?

The hydrogen bomb is the thermonuclear bomb, which has a thousand times more destructive power than the conventional atomic bomb. A small hydrogen bomb can destroy a large city in a matter of seconds.

What is the difference between an atomic bomb and a hydrogen bomb? : Atomic bombs and hydrogen bombs are made in two completely different ways. Another name for the atomic bomb is 'nuclear fission'. The tactic of this bomb is to break a small atom into two or more smaller and lighter atoms. The result is a huge amount of energy and a devastating explosion. Another name for the hydrogen bomb is 'nuclear fusion'. The strategy of this bomb is to turn two or more hydrogen atoms into very large and heavy atoms. Hence its name hydrogen bomb. It brings out a few thousand times more energy than 'nuclear fusion'.

What is the significance of the miniature hydrogen bomb in North Korea?

Very small hydrogen bombs can also be made, which are called 'miniature hydrogen bombs'. As a result, hydrogen bombs can be easily attached to missiles and dropped in remote areas. If North Korea had built a small hydrogen bomb, it would surely have been able to launch it thousands of miles away using intercontinental ballistic missiles.

Atomic bombs and hydrogen bombs are one of the most powerful weapons to destroy human civilization on earth. The power of the atomic bomb is world-renowned But even more powerful is the hydrogen bomb

 As a threat to mankind, each of these uranium-destroying weapons could destroy an entire city, kill millions of people, severely damage the natural environment, and its long-term horrific aggression could have a devastating effect on future generations. The radioactivity of the atomic bomb is a silent and invisible killer.

Renowned author H. G. in the 1914 novel The World Set Free. Wells envisioned a kind of destructive and extremely powerful hand grenade made using uranium. Once this devastating bomb is dropped, it will have an indefinite effect. H. G. Wells introduced the uranium bomb through his novel. In the old days, however, the existence of this devastating bomb was confined to the fictional pages of the novel.

H. G. In 1936, two decades after the publication of the Welsh novel, the possibility of making an atomic bomb arose in a laboratory in Berlin, Germany. In this laboratory it is possible to discover the process of nuclear fission by scientists Ottohan, Lis Mitner, Fritz Straussmann. As a result, the theory of quantum physics became a reality.

When a free neutron strikes the nucleus of uranium, its atoms split in two. As a result, atoms of two completely new substances are formed from the uranium (U) atom. One of these new substances is barium (BA) and the other is called krypton (CR). This process of fission of uranium atoms is called nuclear fission.

With the creation of two new atoms, 3 new neutron particles and a huge amount of energy are released. The three new neutrons created hit the other three intact uranium atoms again. The same thing happened again. This process continues unabated. Which is called chain reaction. This process is accomplished in a very short time and instantly spreads from a very small space to a very large space in the form of heat energy, mechanical energy and electrical energy.


This new type of nuclear reaction produces about 50 million times more energy than a chemical reaction. How is this huge power created? After the atom splits, the uranium atom disappears and some mass loss occurs. That is, the mass of the two new substances is less than the mass of the uranium atom. This lost mass is converted into energy.

Since the outbreak of World War II, there has been an invisible Cold War between the American scientist Heisenberg and the German scientist Robert Oppenheimer. During this time, Germany and the United States began to compete with each other for nuclear weapons.

Oppenheimer worked tirelessly with the top American scientists in 1943 to build an atomic bomb under the Manhattan Project. On the other hand, Heisenberg and his colleagues were on the verge of making an atomic bomb when a terrible explosion occurred. They somehow managed to get their lives back, but with their long work, that laboratory in Leipzig was shattered before everyone's eyes.

Following the explosion, rumors spread that Germany was on the verge of developing an atomic bomb. The Americans consider the German laboratory accident as a symbol of German success. The Americans benefited from this misconception. The news made Americans desperate to get their work done quickly.

Heisenberg, on the other hand, was under intense stress after the Leipzig laboratory was completely destroyed. The Nazis made it clear to him,

By 1945, Germany's plight had reached a tipping point due to some wrong decisions. On May 3, 1945, Germany's top scientists, including Heisenberg, were captured by Allied forces. Heisenberg was sent to England under tight security because he was one of the world's top scientists.

Oppenheimer was on the brink of success with all kinds of government support. In recognition of his outstanding contribution to the discovery of the atomic bomb, he is widely regarded as the "father of the atomic bomb." He and his research team were able to make three atomic bombs by July 1945. Three of these atomic bombs were plutonium-rich bombs - Fatman and Gadget. The other is a uranium-rich bomb - the Little Boy.

Three newly discovered American bombs were then awaiting experimental detonation. At an important meeting of the White House, US President Truman authorized the experimental detonation of an atomic bomb made by scientists. The mission was named "Trinity Test" at the White House meeting.

The gadget, a plutonium-rich atomic bomb, was taken to the Alamogordo test site in New Mexico after receiving presidential approval. 

There, scientists tested the bomb several times and sent a green signal. The world's first atomic bomb was detonated at a safe distance after scientists received the green signal.

Within seconds of the eruption, a giant mushroom-shaped smoke about 40,000 feet high covered the sky in New Mexico. Oppenheimer was delighted to see the success of his discovery.

The Trinity Test bomb was so powerful that its exploding surface temperature exceeded the sun's surface temperature. Even this temperature was about 10,000 times higher than the surface temperature of the sun.

How many atomic bombs are there in a country?

Nine countries currently have 16,300 atomic bombs. However, efforts to reduce the number of these bombs continue. The detonation of an atomic bomb and the preservation of a bomb in a country's arsenal is a matter of great controversy. Even after the explosions in Hiroshima and Nagasaki, the bombs have been detonated more than five hundred times experimentally and for demonstration. Currently the countries that have detonated and stockpiled nuclear bombs are the United States, Russia, the United Kingdom, France, China, India and Pakistan. It is also widely believed that North Korea, Iran, Israel and South Africa have nuclear weapons.

The total number of "effective" nuclear weapons in the world is 16,300. The United States and Russia have about 14,000 weapons in their possession.

Russia has the most atomic bombs, according to the Stockholm International Peace Research Institute (SIPRI). The number of such bombs in the country is more than 6,500 The country conducted its first nuclear test in 1949.

Second United States: The United States built the first atomic bomb and is the only country to have used it in war. The country now has more than 6,000 atomic bombs.

The rest are divided into seven other nuclear-armed countries. These include the United Kingdom (215), France (300), China (280), India (120), Pakistan (120), Israel (60) and North Korea (<10). China, France, Russia, the United Kingdom and the United States are the five nuclear-armed states in the world that have been formally identified under the Nuclear Non-Proliferation Treaty. The treaty gives them a good idea of ​​their arsenal and legitimizes it, but the states mentioned in the treaty do not recognize their permanent preservation or preparation. These states are committed to disarmament. Pakistan, India, Israel and North Korea have not signed the agreement. The total number of nuclear weapons in the possession of the countries is 340.

Mankind will one day be wiped out by a nuclear war. Nuclear weapons have become one of the most powerful means of killing and destroying man-made, a factor of strategic scale. At present, the possession of nuclear weapons has become a reliable and perhaps the only guarantee of the security of which state? When World War III starts, it will destroy the very existence of the whole world.
