Annals of the ARS – Anniversary volume, 1 – 2006 39 INTERNATIONAL YEAR OF PHYSICS: ALBERT EINSTEIN – A CENTURY FROM THE THEORY OF RELATIVITY: 1905-2005 Mărgărit PAVELESCU 1 Abstract. Year 2005 was declared the international year of physics because one accomplishes 100 years from the launching of relativity theory by Albert EINSTEIN (AE). AE (1879-1955), German-born American physicist and Nobel laureate, best known as the creator of the special and general theories of relativity and for his bold hypothesis concerning the particle nature of light, is perhaps the most well-known scientist of the 20th century. The paper was presented in the autumn of 2005 in the meeting of section of mathematics and physics of the AOS-R. The paper is destined to pay homage to scientific personality of AE, making a short presentation of his biography and of initial publications. Further, it discusses the Einstein‟s special theory of relativity from 1905 and early reactions to it. After that, the central ideas of the general theory of relativity and the modifications of it are exposed. Further, are enumerated the performances of AE in social plan. Finally, the conclusions concerning his scientific opera are presented. 1. SHORT BIOGRAPHY AE was born in Ulm on March 14, 1879, and spent his youth in Munich, where his family owned a small shop that manufactured electric machinery. He did not talk until the age of three, but even as a youth he showed a brilliant curiosity about nature and an ability to understand difficult mathematical concepts. At the age of 12 he taught himself Euclidean geometry. AE hated the dull regimentation and unimaginative spirit of school in Munich. When repeated business failure led the family to leave Germany for Milan, Italy, AE, who was then 15 years old, used the opportunity to withdraw from the school. He spent a year with his parents in Milan, and when it became clear that he would have to make his own way in the world, he finished secondary school in Arrau, Switzerland, and entered the Swiss National Polytechnic in Zürich. AE did not enjoy the methods of instruction there. He often cut classes and used the time to study physics on his own or to play his beloved violin. He passed his examinations and graduated in 1900 by studying the notes of a classmate. His professors did not think highly of him and would not recommend him for a university position. For two years AE worked as a tutor and substitute teacher. In 1902 he secured a position as an examiner in the Swiss patent office in Bern. In 1903 he married Mileva Marić, who had been his classmate at the polytechnic. They had two sons but later have divorced. AE later remarried with his cousin. 2. EARLY SCIENTIFIC PUBLICATIONS In 1905 AE received his doctorate from the University of Zürich for a theoretical dissertation on the dimensions of molecules, and he also published three theoretical papers of central importance to the development of 20 th -century physics.
