A Brief History of Atomic Models - From Democritus to Quantum Theory

Explore the evolution of atomic theory in this comprehensive 33-minute video. Journey through the history of atomic models, from ancient philosophical ideas to modern quantum concepts. Discover key contributions from Democritus, Archarya Kanad, Dalton, Thompson, Rutherford, and Bohr. Delve into fundamental principles like the law of conservation of mass, cathode rays, and the gold foil experiment. Examine Bohr's atomic theory, including orbit stability, electron energy levels, and electromagnetic waves. Investigate the wave nature of matter, de Broglie's equation, and the Heisenberg Uncertainty Principle. Conclude with an introduction to the quantum model of the atom, exploring probability and the limitations of human understanding in subatomic particle behavior.
