What is the difference in the way that a scientist and a historian use time periods?

Historians look more at the big picture than scientists who are concentrating on a specific problem

Explanation: Scientists use time just like they use meters or kilograms. They're interest in the specifics of a situation. What causes it, how long it takes for to happen, for it to end, if it always takes the same amount of time and if not, why not.

Historians look at the bigger picture, the amount of influences over a time period, how history repeats itself over time, what changes over time at a larger scale and so on.
