*PROPERTIES OF THE GLASS
The cristalline material is peiodic. 
The átomos in the cristal are always at
specific distantes is Know as traslation or
period of PIU.

When we go to walk, jump or run, we do this with involuntary stimuli we do it by order of our brain, always coordinated, all our muscles and tendons put hands to work, and in this way we can make the action of jumping or kicking.

Swing arms to walking has no other tasks that keep the balanced trunk and save energy, according to experts. For example, when you move the right leg to take a step, body performs a rotational movement around the vertical axis that passes through the torso. By the principle of conservation of angular momentum, the trunk reacts in the opposite direction. At the same time, the right arm moves backwards, and the left forward, to help preserve the balance.

There are two basic types of movement, flexion and extension, which are not precise terms. We describe these movements in this way: Flex: produced a filling and a lateral extension of the skull. The body through the communication fibridal, enter external rotation. Extension: Occurs a recess and a lateral shortening of the skull as well as a lengthening in the anterior and posterior part of the skull, producing an internal rotation.

THE SILK

Silk comes from an insect larvae called mulberry silkworm.
It is the material of the cocoon before the worm became a butterfly.

It is a protein fiber wich can be used to make textiles. The silk fiber can be woven on a loom.


The silk moth lays the eggs on a special paper. The silkworm eat fresh muberry leaves. After 35 days the caterpillar is prepared to build the cocoon. It uses liquid silk and nedd 2-3 days to finish the cocoon. The fiber is about 1 mile long. To take the silk the caterpillars were killed. The silk farmers boil the cocoon.









The main producers of silk are now China, India, Uzbekistan, Brasil, Iran, Thailandia, Vietnam, Korea, Romania y Japan.


History:

The first person to wear silk was the chinese emperor at 1500 b.c.
At this time only the Emperor and his family were allowed to use silk.

The first examples of silk found were from 3630 b.c.

Because of his shimmery it was very appreciated and with the time the silk get very famous in all the world. The tissue obtained is very soft, light and beautiful.
