The full name of the famous scientist known for the theory of relativity is Albert Einstein. His groundbreaking work fundamentally altered our understanding of physics, particularly through his theories of special relativity, published in 1905, and general relativity, published in 1915. Einstein’s theories introduced revolutionary ideas about the nature of space, time, and gravity, culminating in the iconic equation E=mc². His contributions to theoretical physics earned him the Nobel Prize in Physics in 1921, solidifying his status as one of the most influential scientists in history and changing the course of modern science.
