Psychology in Our Life
As we all know,psychology plays an important role in our daily life.
The most common principle is the gravity.
If there is no gravity,can we fly in the sky?
Of course not!
It will be a terrible disaster!
The air will flee from the earth and the atmospheric pressure will be reduced quickly!
If that really happens,all the living creatures will die of lacking of oxygen or blow out from themselves!
You see,how important gravity is in our life!
In the other hand,the friction is also very important.
Because of the friction,we can walk smoothly and the cars can stop quickly.
It seems so insignificant that sometimes we hardly forget it.
But it is as important as the gravity.
Maybe the psychology in our life is an invisible angle.
