[edit] Emergence

* Higher level properties don't exist in lower level
	for example:  Salt => 2 substances neither has saltiness, when put together that has 
		      saltiness property. (What is the cause?)
* For computer science, emergence is the properties of the outcomes of the implementation
        for example: Software => How users use the software (its properties) without acknowledging 
		     the implementation

[edit] Static

[edit] Dynamic
