Einstein's 1905 Papers and the Nature of Light

In 1905, Albert Einstein published influential papers that marked the beginning of modern physics. While many know his famous equation E=mc^2, fewer understand his contributions to the concept of light as particles. This video explores Einstein's March 1905 paper, where he proposed that light consists of particles, or 'light-quanta', challenging the then-prevailing wave theory of light. His theory was supported by experiments involving electron ejection from metals, leading to his Nobel Prize. The video celebrates Einstein's legacy on the 133rd anniversary of his birth.
