The breadth of knowledge there is no limit because of all the things that exist outside and inside all human knowledge can be learned so that it can emerge and can be studied as a science that is able to contribute to the advancement of the modern era to the era of very forward looking.

Can not be separated from the existing activities daily life which in this case will be described in detail and hopefully can become a literature that helps to contribute to science.
