Once Albert Einstin climbed a ladder

Once he climbed a ladder to change the picture on the wall. His foot slipped and he fell to the floor. Quickly recovering from the fall, he took out a paper and pen and began working to the causes of the fall. Like the ball of the apple in Newtons Garden, this incident led him to restructure the theory of gravitation. He was Albert Einstein.

Einstein was born at Ulm in Germany. He learns piano from his mother. Right from his childhood he was interested in science. He was sharp in mathematics but a mediocre in other subjects.

These electrons he called photo electrons and the effect ‘photoelectric effect’. He was awarded the 1921 Noble Prize for his discovery of the law of Photo electric effect.
