The History of Physics (Part 2)

The video explores the evolution of atomic theory, starting with the discovery of the electron by JJ Thompson and the nucleus by Rutherford. It delves into Einstein's theories of relativity, explaining concepts like time dilation. The video also covers superconductors, superfluids, and the use of cloud chambers in particle physics. It discusses wave-particle duality, nuclear fission, and the discovery of quarks. Finally, it introduces string theory and the standard model, highlighting the Higgs boson and the quest for a unified theory.
