Ramesh and his parents are at the railway station. They are waiting for the arrival of their train to Hyderabad.  Ramesh is very excited because he is going to his uncle’s house to spend his summer vacation.  When the train arrives, all of them get into it.  Ramesh- father, I like this journey very much. Father- then you should thank the person who invented the locomotive.  Ramesh- oh! How great! Who is that, dear father? Father- in 1802, Richard Trevithick, a British engineer, made the first locomotive. Later on, George Stephenson, the `Father of British Railway,’ improved this locomotive which became popular. Today, Japan, Germany and France have the fastest trains that run at speeds of more than 400 kilometers an hour. Ramesh: - very interesting. Father, please tell me about some inventions. Father- do you know? We can also fly in the sky like birds even if we do not have winged. How can we do that? Ramesh: - in an aero plane. Father: - yes, very good. In 1903, two American brothers, Orville Wright and Wilbur Wright, built the first aero plane called flyer-I. The first aircraft flown by the Wright brothers is displayed at the National Air and space Museum in Washington, USA. Ramesh- how wonderful! Father- aero planes land and take off at the air port. A pilot flies the airplane. An aero plane is the fastest means of transport by air. Ramesh: -- father, I love cars very much. Please tell me about them Father: -- sure, my dear son. Karl Benz, a German engineer, built the petrol –driven car in 1885. As a result of people’s interest in his invention, Benz set up the world’s first motor car factory the same year. Later on, Henry Ford realized the need for a cheap, reliable car. He became one of the world’s richest men after he built his `Model T’ or `Tin Lizzie’.  Ramesh- very interesting! Father- now you know that we can travel on land in the air. Do you know that we can also travel in water? Ramesh- yes, father. We can travel on water in a ship. Father- do you know who built the first ship? It was built in ancient Egypt in about 3500 BC. Wait, my cell phone is ringing. We should thank Alexander Graham Bell because we are all able to get important and urgent messages in seconds.  Ramesh- who is he? Father- Alexander Graham Bell invented the telephone in 1876. Now, there are many kinds of telephones like land phone, cell, video phone etc. ok., now it is getting dark. Let us switch on the light.  Ramesh- yes father. But who invented this bulb? Father- Thomas Alva Edison, an electric bulb. Oh, it is time for songs on radio. Shall we listen to some music, Ramesh? Ramesh: - OK father.  Father- you know, the radio was invented by an Italian, Guglielmo Marconi, in the year 1896. As we cannot take a television everywhere out with us, we can at least keep a radio for entertainment.  Ramesh- but, father, we can watch programs on television. In that way television is most useful, right. Father- that’s true. Do you know who invented the television? The television was invented by John Logie Baird in the year 1926.  Now, I shall tell you about the most interesting means of telecommunication –the computer.  Ramesh- OK., father. Father- the computer was invented by Charles Babbage. He is known as the `Father of computer’. OK. It’s time for us to sleep. Tomorrow, early in the morning, we will be reaching Hyderabad. Good night. Ramesh: - good night, father.
