Editor's Notes
- Hello, I’m Maciek and I would like to introduce some of the most significant American inventions.
- First of all I’m going to present how the plane was invented. People always dreamt about flying. On the grounds of observations of the birds Leonardo Da Vinci projected the model of first hang-glider. The pioneers of flying like German Otto Lilienthal proved that the sailplanes can take the man through the air. In the end of the 19th century many inventors tried to construct the plane that is the glider with engine.
- The Americans, Orville and Wilbur Wrights achieved it in 1903. They invented the plane powered by combustion engine. The first controled flight took place in 1903. It lasted for 12 seconds. The same day brothers performed three flights, the best lasted for 59 seconds and the plane flew 270 metres. This year is considered to be the beginning of planes’ era. But brothers became famous in 1908, when Wilbur demonstrated it in Europe and Orville showed it to the USA Army. On 14th of May 1908 Wrights performed the first flight with passenger, Charlie Furmas.
- You can see that these planes vary a lot from Wrights’ work. They are bigger, faster and safer. The passenger plane can take hundreds of people. The biggest passenger plane is Airbus A380. The best-known companies producing this kind of planes are: Airbus and Boeing.
- The next famous American invention is the manual camera. The first prototype of camera was called Camera Obscura. It was invented in about 1500. How did it work? This device consists of the box with black colour inside. In the one of its wall has a small hole which is a lens, but on the another it is a frosten glass or tracing paper. The light beams go through the aperture, and create the diverted and reduced picture.
- But the first manual camera was the work of George Eastman. It was invented in 1889. The innovation was that the camera had a film where the photos were saved. Thanks to this invention, the photography is known all over the world.
- These are modern cameras. They are so different to those that I told you earlier. They take better photos, with bigger resolution. Some of them are smart, for example they can tell you where and when you took the photograph. The best- known companies producing cameras are: Canon, Kodak, Nikon, Olympus, Panasonic and SONY.
- But what about George W. Eastman? He was born on 12th July 1854. He was an American entrepreneur, the co-founder of Kodak Company. He was a propagator of photographic film. He popularized photography. He died on 14th March 1932.
- That’s all I want to say about the most popular American inventions. I hope I managed to interest you in the topic. Thank you for your attention.
