The theories of classical physics consider waves and particles as different concepts. The advent of Quantum Theoryĭuring the development of classical physics, the physicists had problems explaining experimental results of black body radiation, photoelectric effect, electron interference, and the stability of atoms. For his explanations of the photoelectric effect, he won the Nobel Prize. These theories govern high-speed objects and gravity. A special relativity theory and a general relativity theory are his contributions. Modern physics owes its origins to Albert Einstein. The world of Physics considers Sir Issac Newton to be the Father of Classical Physics for his contributions to this field. Additionally, he came up with the calculus theory.
His theory is the basis of classical physics. It was Sir Isaac Newton who established the laws of motion and gravity. Three scientists have been awarded the title "Father of Physics" at different times, based on their most important contributions.įor his contributions to Astrophysics, Galileo Galilei is known as the Father of Observational Physics. The subject has developed through the efforts of many scientists. Physics encompasses both the study of theoretical and experimental aspects of all-natural phenomena. Physicists now use both theories to approximate the predictions of classical theory. Physical phenomena are explained by quantum theory at a microscopic level, while large-scale physics involving particles closer to the speed of light needs the help of relativity theory. The two theories which laid the foundations of modern physics are the theory of relativity and the quantum theory. These theories gradually gave rise to modern physics. Early in the twentieth century, various physicists and mathematicians made experimental findings that were not explainable by classical physics (which explains normal physical phenomena). Mechanics in the modern era is the study of fundamental aspects of the universe using post-Newtonian theories.
