Edison was a world-renowned inventor with over a thousand inventions, including the light bulb, phonograph, and movie camera. However, growing up in a poor family, Edison only received a few years of formal schooling. At age twelve, he worked as a newsboy on trains. Since he couldn't attend school, he taught himself. With a deep passion for learning, he spent every spare moment reading newspapers and books while working. His father was very strict, requiring everyone to be in bed by 11:30 PM. Since Edison often returned home at 11:00 PM, he had almost no time for his beloved experiments. For a curious mind like Edison's, this was unbearable. He searched for a way to gain his father's support. One day, Edison strung copper wires between trees, connecting his friend's house to his own, and left some newspapers and a homemade telegraph machine at his friend's. When he returned home, his father wanted to read the paper, but Edison said they were sold out. To pique his father's interest, Edison described the fascinating news in detail. Eager to read them, his father agreed to let him use the telegraph to receive the news. Seeing that the homemade telegraph actually worked, His father was impressed by his son's ingenuity. From then on, he no longer stopped Edison's late-night experiments. Through persistent effort, Edison eventually became one of the world's greatest scientists.
