Modern Physics

  • It is an effort to understand the underlying processes of the interactions with matter, utilizing the tools of science and engineering.
  • Generally, the term is used to refer to any branch of physics either developed in the early 20th century and onward, or branches greatly influenced by early 20th century physics.

About Modern Physics

About Modern Physics
  • It is a branch of physics which deals with the post-Newtonian concepts in the world of physics.
  • It is based on the two major breakthroughs of the twentieth century:
    • Relativity
    • Quantum Mechanics.
  • It often involves an advance description of nature through new theories which were different from the classical descriptions and involves elements of quantum mechanics and Einsteinian relativity.
  • So, quantum effects typically involve distances related to atoms. On the other hand, relativistic effects typically involve velocities compared to the speed of light.

Father of Modern Physics

  • Albert Einstein is known as the father of modern physics.
  • As 20th-century scientist, he who came up with the most important ideas.
  • One of the important works of Albert Einstein is the theory of relativity and the famous equation
  • Awarded by the Nobel Prize for physics in 1921 for his achievements in theoretical physics, particularly discovering the laws of photoelectric effect
