What was remarkable about 2005 was perhaps that the United Nations declared it "The world Year of Physics". It was the 100thanniversary of Einstein's theory of relativity and the 50thanniversary of his death. In 1905 Einstein publishedfive highly important essays in the history of science, thus revolutionizing physics. His great achievements can be credited to his impressive powers of imagination, constant questioning, and not giving a fig for authority. It is beyond doubt that Einstein was the greatest scientist in the 20thcentury.
