Activity
An activity takes any duality or dualities except time and fixates their values at a moment.
Such as at 9AM the temperature is 30°C.
Such as at 9AM a city has temperature of 30°C and luminious intensity of 50 candelas.
The interconnection of activities emerges and dissolves
entities.
Such as at a moment the proximity in distance among the cells in an apple creates the entity
of "an apple".
