Telecommunications and the new information networks
Due to the spread of electronic devices, interconnections between them is possible thanks to internet and the web, giving the exciting and extraordinary possibility to share information (and to spread knowledge) all around the world.
In the case of books, digital libraries give the possibility to have the books of all the world in your bookcase (with digital libraries substained by publics or by donations, bookshops and the book market are dead).

Telecommunications are based on signals that reach senses (except touch), so classical books can now merge to illustrations videos and sounds (more generally all Arts that don't need to be touched). Telecommunications are based on photons and not on protons, neutrons and electrons, so they don't need transport of matter (of the paper in case of classical books) (sounds, that are "materia", are generated at the arrival). The new book (e-book) will be ecologically advantageous if it will be visualized below a certain number of times and the number of visualisation devices will not increase (people doesn't acquire a tablet if it has a PC and vice-versa). It is always advantageous when the text is not definitive and other editions are generated (practically this is "necessary" ever).

With the consciousness that also digital telecommunications are fallible.

Another important advantage of the web is that the websurfer can rapidly interact.

In the following of this websiteyou will find Books and ScientificTechnical Posters: the books can only be read, not printed; the posters can also be downloaded and printed, but, please, print them in an "ecological" manner (raw recycled paper, etc.) and only after that they have reached a good maturity.
For books, you can exceptionally buy an "ecological" printed version.
