Nuclear physics and quantum physics are two fundamental branches of physics, but they focus on different aspects of the physical world.
Nuclear physics is primarily concerned with the study of atomic nuclei, their constituents (protons and neutrons), and the interactions between them. It explores phenomena such as nuclear decay, fission, and fusion. Essentially, nuclear physics investigates the forces and processes that govern the behavior of these tiny, densely packed cores of atoms. Applications of nuclear physics include nuclear energy, medical imaging, and understanding stellar processes.
On the other hand, quantum physics, also known as quantum mechanics, deals with the behavior of matter and energy at the smallest scales, typically at the level of atoms and subatomic particles. It introduces concepts that seem strange compared to classical physics, such as wave-particle duality, quantization of energy, and the uncertainty principle. Quantum physics provides the foundational framework for understanding phenomena like superconductivity, quantum entanglement, and the behavior of electrons in atoms.
In summary, while both fields deal with fundamental aspects of physics, nuclear physics focuses specifically on the nucleus and its interactions, whereas quantum physics encompasses a broader range of phenomena at the atomic and subatomic levels. The two fields often intersect, but they maintain distinct areas of study and application.
