Do you all know who invented the bulb? Well, it was, Thomas Edison. His teacher told him that he was stupid and could not do anything. So his mother started to teach him at home, till his mother was in enormous pain and went to the hospital. The doctors could not operate at night due to unavailability of light. This incident immensely saddened Thomas. So from that night, he tried many times to make a bulb but was always unsuccessful. Thomas Edison made 1,000 unsuccessful attempts in making a bulb.
