The History of Physics and Its Applications

The video explores the evolution of physics from ancient times to the 20th century, highlighting key figures and discoveries. It covers Thales' early theories, Archimedes' principles, Ibn al-Haytham's optics, and William Gilbert's magnetism. The contributions of Galileo and Newton to classical mechanics are discussed, along with the development of electricity and thermodynamics. The video concludes with Maxwell's equations and the discovery of radiation, emphasizing the impact of these advancements on technology and society.
