In this course we will take a look at the fascinating personality of Albert Einstein. We will look at both his private life and his scientific achievements. We will follow him on his journey from Bern, where he worked out his scientific theories while working as an office clerk, to the USA, where he wrote his famous letter to President Roosevelt that triggered off the Manhatten Project (the program for the development of the nuclear bomb). We will look at the research that A. Einstein did in the course of his life, its foundations and its consequences.
