Happiness

Happiness has a very important role in the lives of human beings .It can be acquired in two ways that follow:
1. External via (Carnal): external and generate happiness,
2. Internal via (spiritual): generate internal happiness, that is, the happiness thus generated, is spiritual. However humans must seek happiness in both directions in order to create a bliss(An absolute happiness).

FUTURE

My perception of the future. And yours?

Future is something that no one really knows what  it is, but everyone talks about it and plans things ahead due to the sense of something one call "future".Future is a whole which is composed of small segments of time(Infinitesimal segments of time) that enclose small actions(Infinitesimal actions) in a space.It is quite impossible to talk about the past, present and the very future for this states are almost imperceptible. All i can conclude about the future is that it is really an imperceptible state of time that brings the predicted into being.

Na industria electrotecnica usam-se materiais tais como:condutores ,semi-condutores,isoladores,magneticos.esta classificacao eh devida a uma caracteristica muito importante que esses materiais possuiem,que eh a resistividade e a permitividade magnetica no caso de materiais magneticos.


EXEMPLOS DE MATERIAIS ELECTRICOS PARA CADA CLASSE:

1. CONDUTORES: Cobre, Aluminio,Prata,ouro,e ligas metalicas.
2. SEMI-CONDUCTORES: Silicio,Germanio,carbono, Carbeto de silicio(Carborundo)etc.
3. DIELECTRICOS: Ar,Elegas(SF6),Gas carbonico, hidrogenio.
