What is materials science? We could describe it as the study of stuff. Just about everything that pills we use every day — be it the dishes we eat from, the shoes we wear, the CDs we listen to, the skateboard or bike we ride – all of it is made of different kinds of material.
Understanding how these stuffs are put together, how they can be utilized, how they can buy a at a low price generic pills without prescription be altered and made better to carry out more amazing tasks or create completely new kinds of stuffs — this is what materials science is all about.
What exactly are materials?
This is a big question – because materials can be described as the basic substances that make up. They can be natural like wood or can be man-made like plastic. Today there are about 300,000 different kinds of materials that are known. And as scientists continue creating and combining various materials in new ways, the numbers of materials available is almost infinite.
Most materials fit into a few general categories:
Entire periods of human civilization such as the Iron and Bronze Ages have been named after metals. These were the first materials on earth to have been engineered. In today’s times, materials scientists use metals in such ways that no one could have ever pictured even a few years ago – for instance, molding copper into tiny wires several times thinner than a even strand of human hair.
A china teapot is one example of ceramic. Several other kinds of ceramics are also available that can be used in creating tooth and bone replacements, in conducting electricity or super-strong cutting tools. By adding oxygen or nitrogen, metals can also become ceramics.
Silicon is one kind of a semiconductor material. Computer chips, CD, DVD player, telephone, etc. all are kind semiconductors.
Polymers are big molecules that are made of smaller molecules connected together into long, repeating chains. Rubber bands, paints and all kinds of plastic are polymers.
Combinations of materials are known as composites. Composites can be as simple as concrete toughened with steel bars or as complex as a carbon-fiber bicycle.
Every part of a human body is made of a material —muscles, fingernails, bones, hair and skin — all are different kinds of materials found in a human body with remarkable properties that helps one survive – protecting us from heat or cold, keeping us upright, assisting in cutting and grinding food as well.
