Nuclear physics refers to the study of the nucleus and its interactions with other particles. Synonyms for nuclear physics include atomic physics, particle physics, and high-energy physics. Atomic physics refers to the study of atoms and their structure, properties, and interactions. Particle physics studies the fundamental particles that make up matter and their interactions. High-energy physics focuses on the study of high-energy particles and their interactions. These terms are often used interchangeably, but each has its own specific focus within the broader field of nuclear physics. Overall, nuclear physics is a complex and constantly evolving area of study that has important applications in a range of scientific fields.
