ALLOY´S UTILITY:
First we need to know that a alloy is a mixture of a metal and a non metal or two metals, some examples are iron and lead or Carbon (non-metal) and Cupper. The Alloys is used in many ways in our actual community, one of those is something that we use all the days, our money... our peruvian "50 cent", "1 nuevo sol", "2 nuevos soles" and "5 nuevos soles" coins are make up of Copper zinc and nickel. Other thing that we use but we don´t take importance that is a alloy, is the batteries that we use in the cars, that are made of calcium and silver.

PLASTIC´S UTILITY:
The plastic, maybe, is the most important between this three greats discoveries for the humanity, the plastic have a lot of uses, we can make bottle with it and then put soda inside, we use it in the CDs where we have all our information, sometimes in our clothes, in the trash plastic bags, etc.

POLYMER´S UTILITY : Before say why the polymers are important we need to remember that a polymer is a macromolecule (molecules with high atomic mass) made up of monomers. In our world exist a lot of polymers some of them are: polyethylene, polytetrafluoroethylene, etc. This macromolecule help us all the days in many things, like: See tv, use our computers, cook the food in a electric kitchen, give us light, use our vidiogames,etc. How is posible that a little macromolecule can give us all this vagaries? the answer is simple, since 1940 we use the polymers to make electricity cables and sometimes it is a good replacement to the Lead. This macromolecule bring us water to becouse some tubes that transport water are make of polymer.

Why philosophy is important for science? Philosophy is the first breath of the study of science because before the people start to do experiments to probe something, they only use their mind for explain the things that happen all the days. Actually the scientists like Nobel, Rutherford, etc would not do nothing if they wouldn’t use the old knowledge of philosophers like Aristotle or homer that tell us tell us their knowledge about the reality, the creation of earth, what is the body about, etc all that men called philosophers were the people that give the initiative to science giving their believes and not probing it with experiments they only think it, because they don´t have the same recourses that we have now, well some of this philosophers try to probe it but with a different result that we would have now in the present. An example is the theory of the planets that give Aristotle putting the sun in the place of mars and forgiving some planets that are after Saturn and thinking that the sun goes around the planets or when he says that the earth was the center of the universe. I think that if the philosophers wouldn’t think in their theories nobody would put the feet to the bottom and discover that the planets go around the sun, that the sun don´t move around the planet, etc So the philosophy help the science to give a push to people to investigate more about something and give his conclusions after all the investigation bringing new ideas for live and eliminating old ideas. So philosophy is only that men that think about with terms about science? No, a philosopher can be anybody that thinks, like the cave men of the ancient ages were philosophers to and they change the world with their ideas about make fire, chase animals, cultivate, etc. if that people wouldn’t discover that, we would stay in the rock age still today. So on conclusion the philosophy helps science in giving people a push to continue investigating in something and continue advancing with the science. Is very different science from philosophy, the science is science when we have the proves of any experiments if is not experiments, it will be called philosophy.

=**// Silicon: one of the millions of wonders of the modern days //**=

Uses of the silicon
In the modern days silicon is important fot something that we always use, I refer to the PC (Personal Computer), a lot of chips that are in our computers are made with silicon, in other words we need to be greatfull with this element becouse the electronic woulden`t advance without this element and if the electronic woudn`t advance we wouldn`t have ipods, PCs, PSPs, Nintendos, Playstations, and other million of things. In other cases silicon is used to make Silicone that is made with silicon and carbon, hydrogen, or other elements (please don`t confuse with silicon that is what is was talking a moment ago), the silicone is used to make adhesives, lubricants, sealents, etc. But the silicone is most knowed at caused of the meddical aplications that are maded with this some examples are the silicone that women put in her body becouse they don`t feel like thy would like to feel.

Economic impact
Bill Gates is the richest man in the world but his empire couldn`t work without the silicon use for the chips in the computers. so without silicon Bill Gates maybe would be a simple designer. And the medics that wone more in this world are all the medics that practice meddical aplications to the body, the women that would like to improve their body are more all the days, and decide to use this metods to improve their bodies. other case are the companies that make adhesives, becouse the silicon is very good adhesive when we mix it with other element.
