Einstein, Albert

Albert Einstein was a theoretical physicist best known for developing the theory of relativity, which revolutionized our understanding of space, time, and gravity. His most famous equation, E=mc², illustrates the relationship between mass and energy, indicating that a small amount of mass can be converted into a significant amount of energy. Einstein's work laid the foundation for modern physics and has profound implications in areas like cosmology and quantum mechanics. He also received the Nobel Prize in Physics in 1921 for explaining the photoelectric effect, which helped establish the concept of light as both a particle and a wave.
