Albert Einstein
14 March 1879 – 18 April 1955
Was a German-born theoretical physicist who developed the general theory of relativity, one of the two pillars of modern physics (alongside quantummechanics). While best known for his mass–energy equivalence formula E = mc2 (which has been dubbed "the world's most famous equation"), he received the 1921 Nobel Prize in Physics "for his services totheoretical physics, and especially for his discovery of the law of the photoelectric effect". The latter was pivotal in establishing quantum theory.
Near the beginning of his career, Einstein thoughtthat Newtonian mechanics was no longer enough to reconcile the laws of classical mechanics with the laws of the electromagnetic field. This led to the development of his special theory of relativity.He realized, however, that the principle of relativity could also be extended to gravitational fields, and with his subsequent theory of gravitation in 1916, he published a paper on the generaltheory of relativity. He continued to deal with problems of statistical mechanics and quantum theory, which led to his explanations of particle theory and the motion of molecules. He also investigated thethermal properties of light which laid the foundation of the photon theory of light. In 1917, Einstein applied the general theory of relativity to model the structure of the universe as a whole.Einstein published more than 300 scientific papers along with over 150 non-scientific works. His great intellectual achievements and originality have made the word "Einstein" synonymous with genius.Albert Einstein was born in Ulm, in the Kingdom of Württemberg in the German Empire on 14 March 1879
In early 1902, Einstein and Marić had a daughter they named Lieserl, born in Novi Sad where Marić wasstaying with her parents. Her fate is unknown, but the contents of a letter Einstein wrote to Marić in September 1903 suggest that she was either adopted or died of scarlet fever in infancy.[34][35]...
