Example of application of limit in daily life We know that concept of limit plays a central role in calculus.I had find information in internet about the application of concept of limit in daily life but unfortunately I failed to find it. Can anyone give examples?
For instance, the derivative, integral and continuity require the concept of limit. I wonder is there any other application in daily life or certain field.

*

*A derivative is a limit. 

*Speed is the derivative of position

*We use the concept of speed everyday.


Therefore, without knowing, we use the concept of limits everyday.
Or, maybe a more technical answer, when Google is calculating the PageRank of a website, it is actually calculating the stationary distribution of a random process, and this stationary distribution is actually the limit of some sequence of matrices.
