«Edison’s First Invention»
When Edison was a boy of fifteen, he worked as a telegraph operator. He had to be on duty from 7 p.m. to 7 a.m. and give a signal every hour to prove that he did not sleep. The signal were made with astonishing exactness. One night an inspector arrived and saw Edison sleeping in a chair.
He was about to shake him when he caught sight of a mechanism on a table near the telegraph instrument. He waited to see what would happen. When the hand of the clock pointed to the hour, the instrument got busy and one lever threw open the key while the other sent the signal over the wire.
The inspector seized the sleeping boy, roused him and “fired” him. That is why the first of Edison’s numerous inventions was never patented.
Answer the questions:
Who was Edison?
What did he invent?
What mechanism did he invent when he was 15 years old?
Was the inspector glad to see this mechanism?
What did he do?
Did the inspector advise Edison to patent his invention?

Science is important to most people living in the modern world for a number of reasons. In particular, science is important for world peace and understanding, for understanding of technology, and for our understanding of the world.
Science is important for world peace in many ways. On the one hand, scientists have helped to develop many of the modern tools of war. On the other hand, they have also helped to keep the peace through research, which has improved life for people. Scientists have helped us understand the problem of supplying the world with enough energy; using energy of the sun and of the atom. Scientists have also analysed the world's resources. Scientists study the Universe and how to use its possibilities for the benefit of men.
Scientists are also important for everyone who is affected by modern technology. Many of the things that make our lives easier and better are results of advances in technology. In some cases, such as technology of producing salt from ocean water, technology may be essential for our lives on Earth.
Scientists are learning to predict earthquakes, to study many other natural events such as storms. Scientists are also studying various aspects of human biology and the origin and development of the human race. The study of the natural world may help improve life for many people all over the world.
Basic knowledge of science is essential for everyone. It helps people to find their way in the changing world.
