 The predictable flow with straight particle paths is called '''“laminar”''' and often has a smooth appearance like the calm river. If we know the direction of flow at one time, that is sufficient information to predict the direction of flow at a later time.

 * 10. So if you know the direction that the molecule is travelling at the start time, would you be able to predict the direction it is flowing at the end time? In other words, is knowing the starting direction sufficient information to predict the direction at a later time?
