 Kim (1976) provides a more detailed fine-grained theory of events. According to him, events are individuated by the properties or relations they involve, the objects which exemplify those properties or relations, and the times during which they exemplify those properties or relations. For instance, the event of the ball rotating is the triple of the property of rotation, the object of the ball, and the time interval during which the ball rotates: ⟨is rotating, the ball, t1–t2⟩. And the event of the ball heating is the triple of the property of heating, the object of the ball, and the time interval during which the ball heats: ⟨is heating, the ball, t1–t2⟩. These two triples involve different properties, so they are different events.
