Splitting the Invisible

At the heart of nuclear power is a process called fission. Imagine an atom as a tiny, tightly packed solar system. In specific elements like Uranium-235, the center of that atom—the nucleus—is slightly unstable. When we fire a tiny particle called a neutron at it, the nucleus absorbs the hit and splits apart. This split releases a burst of energy in the form of heat, along with a few more neutrons. These new neutrons then hit other nearby atoms, causing them to split too. This creates a chain reaction. In a nuclear power plant, we control this chain reaction carefully inside a reactor. The heat produced by this constant splitting is used to boil water into steam, which then spins a giant turbine to generate electricity. It is essentially a very sophisticated way to boil water to power our lives!
