Albert Einstein was born in 1879. As a boy he was not happy in school. He seemed to be slower than others and he often failed in his exams. Most of his teachers did not like him. His parents, however, loved him very much. They often said to the teachers, “Albert is a bright boy. He failed in some of the exams because he had no interest in those subjects.” They believed their son would do something great. One day, the Einsteins and their friends were having a picnic by the riverside. Someone said, “See how the other children play and laugh, but not Albert. He just sits and looks off across the river.” Albert’s mother heard this and said, “Albert is quiet, because he’s thinking. Let’s wait and see. He’ll become a great scientist, I believe.”

She was right. Later, Albert became one of the greatest scientists in the world. He won the Nobel Prize for physics in 1921.
