Albert Einstein, born on March 14, 1879, in Ulm, Germany, is widely regarded as one of the greatest physicists of all time. His revolutionary theories reshaped our understanding of the universe and laid the groundwork for modern physics. This article explores Einstein’s life, his groundbreaking contributions to science, and his enduring legacy.

Early Life and Education
Albert Einstein showed early signs of intellectual curiosity and independence. He attended the Swiss Federal Polytechnic School in Zurich, where he studied physics and mathematics. Despite challenges in his academic career, Einstein demonstrated exceptional analytical skills and a keen interest in theoretical physics.
Theory of Relativity
Einstein’s most famous achievement is the theory of relativity, which fundamentally altered our concepts of space, time, and gravity:
Special Theory of Relativity: Published in 1905, Einstein’s paper on the special theory of relativity proposed that the laws of physics are the same for all non-accelerating observers and that the speed of light in a vacuum is constant. This theory introduced the concept of spacetime—a unified framework for understanding the physical universe.
E=mc²: Einstein’s equation, E=mc², emerged from his theory of relativity. It states that energy (E) equals mass (m) times the speed of light squared (c²), revealing the equivalence of mass and energy. This groundbreaking formula has profound implications for nuclear physics and the development of atomic energy.
General Theory of Relativity: Building upon his earlier work, Einstein developed the general theory of relativity, published in 1915. This theory posits that gravity arises from the curvature of spacetime caused by the presence of mass and energy. General relativity has been confirmed through numerous experimental tests and is the basis for our understanding of cosmology and black holes.
