Introduction to Physics

Definition of Physics

• Physics is the natural science of matter, involving the study of matter, its fundamental constituents, motion, behavior, energy, and force through space and time.

Goals and Scope of Physics

• The main goal of physics is to understand how the universe behaves.
• Physics is one of the most fundamental scientific disciplines.
• Physics intersects with many interdisciplinary areas of research, such as biophysics and quantum chemistry.

History of Physics

• Physics is one of the oldest academic disciplines, with its roots in natural philosophy.
• During the Scientific Revolution in the 17th century, physics emerged as a unique research endeavor.

Impact of Physics on Other Disciplines

• New ideas in physics often explain the fundamental mechanisms studied by other sciences.
• Physics suggests new avenues of research in mathematics, philosophy, and other academic disciplines.

Applications of Physics

• Advances in physics often enable new technologies, such as:
  • Electromagnetism, solid-state physics, and nuclear physics leading to TV, computers, domestic appliances, and nuclear weapons.
  • Thermodynamics leading to industrialization.
  • Mechanics inspiring the development of calculus.
