Passage
Paul Johnson was 16 years old. He was very shy and didn't talk much to anyone. But his
science teacher, Mr Smith, noticed that there was something different about him and he showed
great concern for Paul.
Paul didn't talk much to anyone but he did talk with Mr Smith. "I want to learn all about
science," Paul said. He began to study science in the first-year class. After a few days, he
appeared in the second-year class. Paul studied very hard. Soon he knew everything that second-year
class was learning. Then he read all the science books in the school library.
One day after school Mr Smith found Paul in the classroom working on the blackboard. Paul
was drawing pictures.
"What are you doing?" asked Mr Smith, with interest. "What are these drawings about?"
"I want to invent things. These are the drawings of my first invention," Paul answered.
"What's your invention?" Mr Smith said.
"I have an idea for television--for a way of sending pictures through the air," Paul answered.
"Please let me tell you about it, Mr Smith. You are the only person who can understand what I
have done." It's amazing that a boy of 16 showed his teacher drawings for television.
