Albert Einstein revolutionized physics with his ground-breaking theories, particularly the theory of relativity, which transformed our understanding of space and time. His equation, E=mc², demonstrated the equivalence of mass and energy, laying the foundation for modern physics. Einstein's work challenged traditional Newtonian mechanics, leading to profound implications for both quantum mechanics and cosmology. His theories provided insights into the structure of the universe, contributing to the development of technologies like GPS. Einstein's ability to think outside conventional norms paved the way for future scientific innovations.
