Quantum Fields: The Most Beautiful Theory in Physics

Explore the fascinating world of Quantum Field Theory (QFT) in this 15-minute video lecture. Delve into the historical perspective of modern physics, starting with the advent of Quantum Mechanics and its limitations. Discover how QFT addresses these problems and provides a more comprehensive framework for understanding particle physics. Learn about the concept of fields extending throughout spacetime, the creation and annihilation of particles, and how QFT explains force mediation and decay. Examine the strengths of QFT as a relativistic theory that avoids causality violations, while also acknowledging its current limitations, such as the absence of a quantum theory of gravity. Gain insights into why QFT is considered one of the most beautiful theories in physics and how it forms the basis of the Standard Model of particle physics.
