Press

The press was created by Johannes Gutenberg, it wass created abaut 1440. Before, the books were published in manuscripst, the manuscripst were wrotten by monks. The old woman makes of fabrics was adopted as press by Johannes Gutenberg for the press

MP3

MPEG-1 Audio Layer 3, more commonly referred to as MP3, is a patented digital audio encoding format using a form of lossy data compression. It is a common audio format for consumer audio storage, as well as a de facto standard of digital audio compression for the transfer and playback of music on digital audio players.
MP3 is an audio-specific format that was designed by the Moving Picture Experts Group as part of its MPEG-1 standard. The group was formed by several teams of engineers at Fraunhofer IIS in Erlangen, Germany, AT&T-Bell Labs (now a division of Alcatel-Lucent) in Murray Hill, NJ, USA, Thomson-Brandt, and CCETT, as well as others. It was approved as an ISO/IEC standard in 1991.
The use in MP3 of a lossy compression algorithm is designed to greatly reduce the amount of data required to represent the audio recording and still sound like a faithful reproduction of the original uncompressed audio for most listeners. An MP3 file that is created using the setting of 128 kbit/s will result in a file that is about 1/11th[note 1] the size of the CD file created from the original audio source. An MP3 file can also be constructed at higher or lower bit rates, with higher or lower resulting quality.
The compression works by reducing accuracy of certain parts of sound that are deemed beyond the auditory resolution ability of most people. This method is commonly referred to as perceptual coding.[5] It internally provides a representation of sound within a short-term time/frequency analysis window, by using psychoacoustic models to discard or reduce precision of components less audible to human hearing, and recording the remaining information in an efficient manner.
This technique is often presented as relatively conceptually similar to the principles used by JPEG, an image compression format. The specific algorithms, however, are rather different: JPEG uses a built-in vision model that is very widely tuned (as is necessary for images), while MP3 uses a complex, precise masking model that is much more signal dependent.

INVENTIONS

THE PEN.
The pen was invented by hungarian Ladislao Josef Biro and chemist Georg Biro. The pens were manufactured in 1940.

THE ZIPPER.
The zipper was invented by Gideon Sundback. The zipper was created in 1912.The zipper was used for textile.

THE BULB.
The bulb was invented by Thomas Edison.The bulb was created on 21st Octuber 1879. The buld was a very important invention.

La bombilla

The bulb

It was invented by Thomas Edison. It was in 1897, the United States.
Before the invention, the way they light up a room or somewhere else was by candles, fires, oil lamps, etc.
The first materials were: glass bulb, a carbon filament and connectors.
It was a great success leave a lit incandescent filament for several days.
Since then, the bulb was recognized as a new invention.
It was very useful, because with the previous lighting methods many of the homes were victims of fires for any fall or misuse them.

EL TELEVISOR

The television is a way of very important communication that comes to all the homes and to the social classes as which it has great influence in the behavior of the individuals and even more in the children.

The television, typical phenomenon of our times, he presents multiple facets of general interest for the individuals, the characteristic of the T.V. is that of being a way of communication of mass due to which numbers and varied interests center concerning them since it is the programming that transmits. It is the way of communication that major influence has inside the homes, on having placed as a social organization, as a culture to socialize that takes immersed a study of life, joined needs, aspirations and ways of thinking and to act with the intention of users' mass that answers to the interests of the economic dominant groups.

The television is born from the conjunction of a series of phenomena and simultaneous investigations but developed aisladamente. The original discovery of the " photo cables " in the middle of the 19th century (The word Television would not be used but until 1900), owes his advances and I develop several investigators who experimented with the transmission of images route electromagnetic waves.

From the 50s, the television has turned into the way of excellent communication. Evidently, his history goes back several decades behind, but the authentic revolution, in his days, is not comparable, with no other.

The prehistory of the television starts, in strict sense, of the most elementary technical discoveries that made possible the transmission distantly of the image in movement. Globally, since it would happen with the radio, it must differ between the technical procedures that allowed to send the first images or sounds of an issuer to a recipient and the moment in which the same sign managed to be caught by a high number of recipients and to turn the simple way of communication into social phenomenon. The remote beginning of the age of the television they depart from the discovery of the selenium, an indispensable metalloid in the composition of the new invention. But when Berzelius discovered it, in 1817, nobody was thinking about similar usefulness. Equal it would happen twenty-two years later, in 1839, with the demonstration - at the expense of Becquerel - of the electromagnetic effects of the light.

The advances in the investigation of three scientific different areas made possible to turn the television into an independent reality: the first one, the photoelectricity, or capacity of some bodies to transform the luminous energy; the second one, the processes of analyses capable of separating into its elements a photography in lines and clear and dark points, and to return it later to his original form; the third one, the advances in the manipulation of the faeces of electrons, that would make possible repeat this process of decomposition and restitution of images twenty-five times per second.

I have chosen this song because is my favourite.

"The winner takes all, the loser standing small... beside the victory
that's her destiny [...]"
