Albert Einstein was born in 1879 in the German city of Ulm. He was no prodigy as infant. In fact he was so late to speak that his parents were concerned he was
fool. In school, his teachers saw no special
talent in him though the signs of his intelligence were there. He taught
himself calculus for example, and it is said that his
teachers seemed a little afraid of him because he
asked questions they could not answer. His gift was no secret. At the age of
16, he asked himself whether a light wave would seem
stationary if one ran with it. It may seem like a strange question, but it shows that Einstein was digging deep to the heart of a problem. Ten years later would arise his theory of relativity.
