Answer to Question 1

Answer: Chaos is a condition that occurs in physical systems that makes it impossible to precisely predict how a system (such as the state of the atmosphere) will appear some time in the future. Chaos arises because small errors in the input value of a variable (or even round-off error) can become magnified in time. This situation is referred to as sensitive dependence on initial conditions. It is a serious problem for weather forecasting because the initial conditions are never known exactly.

Early clockmakers apparently thought that the IIII balanced out the VIII (used for the number 8) on the clock face and that it just looked better.
