In process of studying Buddhism and Physics. I found out Impermanent law and Cause & Effects law of Buddha is explained scientifically way by Chaos theory.
The Buddhism is humanistic ethics which based on the rule of causes and effects. Living the life useful for yourself , for others and for beings.
Intelligent people often live the life useful for themselves, for others and for animals. Ignorant people often live the life harmful themselves, for others and for animals.
