Contemporary research in physics can be broadly divided into nuclear and particle physics; condensed matter physics; atomic, molecular, and optical physics; astrophysics; and applied physics.

Physics is the branch of science that deals with the structure of matter and how the fundamental constituents of the universe interact. It studies objects ranging from the very small using quantum …

Physics the study of matter, motion, energy, and force.

Physics is a discipline that appeals to problem solvers who are curious about the world. Physicists work to gain knowledge of the mysteries of the universe—visible matter makes up only about 5 percent of …

Physics is concerned with describing the interactions of energy, matter, space, and time, and it is especially interested in what fundamental mechanisms underlie every phenomenon. The concern for …

To celebrate the International Year of Quantum Science and Technology, Physics Magazine has assembled a special collection tracing the field’s most consequential breakthroughs.

The Physics Classroom Tutorial presents physics concepts and principles in an easy-to-understand language. Conceptual ideas develop logically and sequentially, ultimately leading into the …

The Physics Hypertextbook is a reaction to three big problems with textbooks: lack of writer's voice, layouts that reduce readability, and outdated economics.

Accelerate your understanding of how matter and energy work. These physics resources introduce the history of the field and simplify its major theories and laws.

Physics is often described as the study of matter and energy. It is concerned with how matter and energy relate to each other, and how they affect each other over time and through space.
