What is nuclear physics?
Nuclear physics is the study of the atomic nucleus, including its properties, structure, and interactions. It involves the study of the behaviour of subatomic particles, including protons and neutrons, and the energy and matter that they produce.
What are the impacts of nuclear physics on modern society?
Nuclear physics plays a crucial role in many areas of science and technology, including nuclear power, nuclear medicine, and the study of the origin and evolution of the universe. It also has important applications in the development of new materials, such as radiation-resistant materials for use in nuclear power plants, and in the study of the fundamental building blocks of matter.
