Anti-Matter and Quantum Relativity

The video explores the evolution of modern physics, focusing on the integration of Einstein's relativity and quantum mechanics. It discusses the wave-particle duality of light and matter, the limitations of the Schrödinger equation, and the introduction of quantum spin and the Pauli exclusion principle. The video highlights Paul Dirac's contributions, including the Dirac equation, which predicts antimatter and integrates relativity with quantum mechanics. It concludes with an introduction to quantum fields and their role in understanding antimatter.
