The computer

We are going to write about the computer. The computer was invented for John Vincent Atanassoff, from New York.

Atanassoff got the idea in 1933 and finished in 1942, he searched help in a student outstanding of the university. They started to work in the basement of the university. The machine had a finally cost of fourteen hundred dolars . The computer was called ABC (Atanassoff-Berry Computer) , it was the first electronic digital computer.

We think that the computer is very useful to work every day in the office, in the house, in the schools, in the hospitals etc... With the computer you can get information for everything you want. You can also make differents projects, in several programs. And now you can buy some others models of computers, one of this is the notebook with differents colors and sizes.

the camera

A camera is a device used to take pictures. It is an ancient mechanism for projecting images where an entire room was the same functions as a camera present on the inside, with the difference that in those days there was no possibility of saving the image unless it be drawn by hand. The existing cameras can be sensitive to visible spectrum or other portions of the electromagnetic spectrum and its main use is to capture the visual field.

The invension of the first Bicycle

The steerable Draisienne was invented by Germany's Baron von Drais invented the Draisienne, a steerable bicycle. It was almost completely made of wood, and having no pedals, riders propelled it by pushing their feet against the ground. At the time, the speed record for this bicycle was 15 km/h. It was used little by little until the 1830's. In 1842, it was equipped with solid rubber tires.

THE ENAMEL

I'm going to write about the enamel.

The enamel coating in the form of glass to beautify and protect the works of ceramics from ancient times was known in Assyrian and Egyptian civilizations, regard to enamel for the decoration of metal objects and jewelry was not known if he was known by the ancient peoples of East since jewelry have been discovered with the appearance of enamel cells appear to be rather fine decorated with stones and broken glass set in the alveoli of the pieces.

The Greeks and Romans made some use of real enamel.

A lot of people known ways and means of decoration in enamel jewelry and furniture and in the formation of patterns and shapes with the same, which are characterized by a different procedure.

These days, many people use it enamel to pain and decorate it nails.

Clock

I'm going to write about clock.

The first watch created by man was a solar one, which indicated the moments of the day by folowingthe shalows of the sun. The chineese used this method about 3000 years before christ. It was also used by the egyptians and incas. These watches had de desadvantage of not being accuarate at dawn, overcasted days and night. The romans marked candles as a rule to control the time at night. In Babylon, Egypt, Grece and Rome they guided themselves by water. The first motor of a clock was created with weights by Pacific in the eight century. In the decade of 1300 was posible to see these watches in cathedrals in Europe. The oldest one is kept in the cathedral of Salisbury.

In 1641 Galileo conceived the principle of the pendlum and Huygens developt the project by the construction of the first mecanical pendlum clock, amazing with rhythmical pendular movements and sweet bell ceremonies.

The Incandescent Lamp

Thomas Alva Edison invented the first Incandescent Lamp on 21th of October, 1879. The bulb remained shining 48 hours uninterrupted. It´s one of the most used inventions in the history. A lot of scientists said that they invented the first Incandescent Lamp, but Thomas was the first who patent it.

The Incandescent Lamp is the one with the shortest life and the and it´s true that is not the one with the best efficient, only the 15% of the energy it´s used for light, but is famous becous it´s the cheapest.

One of the most famous disputes over the patenting of the incandescent lamp was between Thomas Edison and Heinrich Göbel, who said that he invented the fist one at 1854, but many

lawsuits estimated that it was very unlikely that Heinrich Göbel had invented the light bulb on that date, so the invention was attributed to Thomas Edison.

The alarm clock

I'm going to write about the alarm clock. The man who invented it was Levi Hutchins, from USA.

Hutchins got the idea in 1787. People were waking up with the light of sun, but Levi was waking up at 4:00 am, that hour of the day he couldn't see the light of sun. Then, he put number four on a clock and added a lever.

I think the alarm clock is a very intelligent invention, because it is very useful, and I use the alarm clock every day.

The television

This communication system was invented in 1926 by John Logie Baird. (Who was a british physicist). The first television's transmission was on the 20s. Only in the 50s the television was

popularized, in some countries of the world.

The mobile phone

Martin Cooper was a pioneer in this technology, it is considered "the father of mobile telephony" by introducing the first radio in 1973, United States, while working for Motorola, but it was not until 1979 when the first trade in Tokyo, Japan by NTT company.

Over the years the movile phones have improved technologically. 

Now there are a lot of trademarks, and almost all the mobile phone have camera. Few mobile phones have bluetooth, the bluetooth serves to pass archives to other mobile phones, there is a similar thing call infrared, its worst than bluetooth. 

Now, there are mobile phones with top, and without it. 

Dj Tray

The DJ Tray or Music mixer is the "instrument" of the DJs. These, in some way, scratch the vinyl discs and modulate the sounds and the frequency to create a uniform sound.

Some people call that final sound "music", others call them "mix of sounds"; but what I do, is calling them according to the type of sounds, sometimes I call them "music", sometimes "mix", because they are different in every "song".

This Tray have many parts: the most important parts are the turntables (there the Djs put the vinyl discs) and the samplers (frequency gauges).

This Music mixers are used to create electronic music that's awesome.

The Djs were created in the sixties because the sound technology development was very advanced for that age, while in that decade Hip-Hop, Breakbeat and Rap were created.

                        

The Electric Guitar

I´m going to write about the electric guitar. The man who invented it was Leo Fender (August 10th 1909-March 21st 1991) from the USA
Fender designed and built the first electric guitar in 1920. He was looking for a more powerful sound for the guitar because in the jazz bands, the other instruments did not allow people to hear the guitars

I think it is an excellent invention because the electric guitar lets you create very good music for our culture.

alex storie by me and sasha minond

We're going to talk about plastic.
The man who invented it was Leo Hendrik Baekeland from Gante, Belgium.

He got the idea in 1863. He found it when preparing a remix whit carbonic acid whit formalehidon.
We think that is an amazing product, but its too toxic for the earth when it is used in a badly form.
