The cell phone

The telephone was invented in1875 by Alexander Graham Bell.
The wireless communication was born with the radio, invented by Nikolai Tesla in 1880 and it was formally introduced in 1894 by a young Italian called Ggulielmo Marconi.
It was expected that one day, both technologies would be combined in a same device.

The cell phone is very useful when trying to communicate with other people in a place where there is no normal telephone; there is no need to be connected to any base.
Nowadays there are few people who don’t own one, and this is because it is a very practical device.

The computer.


I am going to write about the computer. The man who invented it was John Atanasoff. He was born in New York in 1903.
This wonderful invent is a machine that can make logic and mathematic operations. Atanassoff started to invent his digital machine in 1933, helped by one of his students, Clifford Berry.
This machine was ended in 1942 and it was called ABC by Atanassoff-Berry computer company.


I think it is a very important invention because it is necessary to work in this modern world. It help you to look for information and to be connected with people who live in all the world.

Shoes

In 1290 nobody had shoes.
In 1291 the shoes appeared and the people were very happy but the problem was that the shoes were with cardboard and when it rained the shoes broke.
In 1299 the shoes were made with cloth, its okey that its unfashionable
And finally in 1320 were made of leather that is fashionable and it wasn`t broke and all the people wore them.

I think this invention is practical to wear. When the time is horrible and cold you can were shoes and you arent cold.
