Modern physics is a branch of physics that deals with the study of the behavior of matter and energy at the atomic and subatomic level. The field of modern physics emerged in the early 20th century with the discovery of the electron, the nucleus, and the development of quantum mechanics. In this paper, we will explore the key concepts of modern physics, including the historical background, the principles of quantum mechanics, the atomic structure, nuclear physics, and particle physics.

The early 20th century was a time of great change in the field of physics. The discovery of X-rays by Wilhelm Roentgen in 1895 and the discovery of radioactivity by Henri Becquerel in 1896 marked the beginning of a new era in physics. In 1897, J.J. Thomson discovered the electron, and in 1911, Ernest Rutherford discovered the nucleus. These discoveries led to a fundamental shift in our understanding of the structure of atoms and the nature of matter. harris randy modern physics 2e pdfpdf 1
