Uncertainty means the quality of something being uncertain. Something that is uncertain is still doubtful and there is no surety of it occurring. It applies to prediction of future events, to physical measurements made or to the unknown. Uncertainty is a commonly used term in various fields such as physics, philosophy, statistics, finance, sociology, engineering etc. Uncertain things always have some amount of risk element associated with their execution. Uncertainty should be minimised and one should focus on the certainty of our efforts and accomplishments of our tasks. Uncertain things can never materialise into something substantial eventually. According to Edward Coke, “Certainty is the mother of quiet and repose, and uncertainty the cause of variance and contentions.”
