Albert Einstein
(1879–1955) was a German-born theoretical physicist whose work transformed modern science. He is best known for developing the theory of relativity, one of the two pillars of modern physics, and for the equation E=mc², which revealed the relationship between mass and energy. Einstein received the Nobel Prize in Physics in 1921 for his explanation of the photoelectric effect, which played a crucial role in the development of quantum theory. Beyond science, he was a passionate advocate for peace, civil rights, and intellectual freedom. His curiosity, imagination, and groundbreaking discoveries continue to influence scientific research and inspire thinkers across generations.
