Modern sources of energy are great, but they are not eternal. Reserves of coal, oil and natural gas are inevitably reduced, and the question naturally arises of new sources of energy. Such a source is found: our time can be called the century of atomic energy.
The study of the internal structure of matter, the study of the atom and the structure of its core, the study of radioactive processes occurring in natural substances, led scientists to discover atomic energy. The remarkable French physicist Frederic Joliot-Curie in 1939 for the first time experimentally proved that the fission of uranium nuclei releases energy. You can judge its quantity by such a comparison: when dividing the nuclei of one gram of uranium, you can allocate as much energy as when burning several tons of coal.
Atomic energy can be used for destructive purposes – for creating atomic bombs. As an atomic weapon of extraordinary destructive power, US bombs dropped in 1945 on the Japanese cities of Hiroshima and Nagasaki were used. But the terrible results of these nuclear explosions forced the foremost people of the world to begin a decisive struggle for the prohibition of nuclear weapons. Nuclear energy should be used only for peaceful purposes.
Atomic energy is very economical. This shows a comparison: during a four-day trip on the largest modern ship, about five thousand tons of fuel is burned, and if this ship worked on nuclear fuel, then for such a journey it would take less than two kilograms of fuel.
However, nuclear power is fraught with a significant threat to humanity. People really thought about this after the Chernobyl disaster. The tragedy of Chernobyl claimed many lives, had a detrimental effect on the environment. For a long time we will pay for the irrational behavior of our rulers who tried to hide from the people the scale of this nuclear catastrophe.
After the Chernobyl lesson, people became vigilant, they will not allow a peaceful atom to destroy life on Earth.
