Trial and error is an experimental method of problem solving‚ repair‚ tuning‚ or obtaining knowledge. "Learning doesn’t happen from failure itself but rather from analyzing the failure‚ making a change‚ and then trying again."

The values of these quantities should be presented in terms of Significant Figures as follows. For example‚ the location of the arrow is to be determined in Fig. 1. It is obvious that the location is between 1 cm and 2 cm. The correct way to express this location is to make one more estimate based on your intuition
