ABSTRACT
When the old man entered, silence fell suddenly upon the 60 or so students assembled in Room 307 of the Palmer Physical Laboratory, on that 14th of April, 1954. The students were emotional and excited. Everyone knew that it was an exceptional event, without a doubt the only time in their life that they would see, in flesh and blood, and hear the speech of the greatest physicist of all time, the living legend of twentieth-century science: Albert Einstein. They were going to attend the great man’s final lecture.
