Being a physics student we have only 3 dimension of space but we have a 4th dimension which is time. So thinking in that way we can think of an array of any dimension(1D or 2D or 3D) whose values differ with time or an array which keeps the record of every array whose values changed with time.
It seems to be quite known to us. For example the "ATTENDANCE REGISTER" which we usually have in our classroom.
This is my view to it.
That's it.
Enjoy :-)
