Since the early days people have been inventing new things to make the life easier. Inventions have changed the world immensely.
A lot of people travel by planes. But it would be impossible without the Wright brothers who made the first flight in 1903.
The Englishman Alexander Graham Bell patented his invention of the telephone in 1876. Very soon in the 20th century the telephone was already in every office and almost every house.
Nowadays the car is probably the most widely used and most useful of all the inventions. The German engineer Karl Benz produced the first petrol driven car in 1885.
Some Famous Inventors
At the beginning of every invention there is its author with his desire to change, create and improve. I would like to say a few words about some of the famous inventors.
Alexander Popov was a Russian physicist who first demonstrated the practical application of radio waves. In 1894 he built his first radio.
Konstantin Tsiolkovsky was the founder of cosmonautics. Initially, he was a Mathematics and Physics teacher. But he never gave up the idea about space travel. His drawings and calculations became the basis of practical space flights.
The progress never stops even for a minute. Modern inventors introduce more complex and more amazing ideas.
Nowadays we widely use computers and cell phones which were invented not so long ago. Another wonderful example is laser with different technologies in medicine, industry and electronics.
