Albert Einstein is often considered the "Father of Modern Physics" due to his groundbreaking contributions to the field, particularly in developing the theory of relativity. His famous equation, E=mc², revolutionized our understanding of energy and mass, illustrating the relationship between the two. Einstein's work has had far-reaching implications for both theoretical and experimental physics, influencing various fields such as cosmology and quantum mechanics. His insights into the photoelectric effect earned him the Nobel Prize in Physics in 1921, further solidifying his legacy. Einstein's ability to merge complex ideas into comprehensible concepts has left a lasting impact on the scientific community.
