What is Uncertainty
1.
The fact of not being known precisely, nor fixed, confident, assured or clearly determined. In other words, it refers to something hesitant, unknown, unstable or likely to change.
Learn more in: Risk and Uncertainty on Technology and Science Under Bayes and Popper's Statements View
2.
The word
uncertainty
means vagueness. It occurs only when the boundary of a piece of information is not clear-cut. The concept of
uncertainty
was first introduced by L.A. Zadeh in his research paper in 1965 as an extension of classical notion of set.

An operational definition of the gap in knowledge that is the start state for information search. There is a cognitive and an affective component to
uncertainty
.
Learn more in: Information Need and the Beginning of Information Search
4.
Describes any situation without certainty, whether or not described by a probability distribution.
Uncertainty
is caused by natural variation and/or incomplete knowledge (lack of understanding or insufficient data).

The situation where less-than-perfect knowledge exists about a particular problem or decision requirement. There exists a wide variation in terms of degrees of
uncertainty
from extreme
uncertainty
(i.e., very limited knowledge of outcomes or likelihood of their occurrence) to near certainty (i.e., almost complete knowledge of the outcomes and the likelihood of occurrence). Generally, an uncertain decision situation refers to one containing ambiguity about part or all of the decision parameters.

Uncertainty
includes incertitude (the exact value is not known) and variability (the value is changing).
Uncertainty

Uncertainty
means not-certainty; throughout the submergence into the nature of time; namely by folded time and lived time awareness, was discovered that all the “not-words of time”—such as
uncertainty
, impermanence, indeterminate, incompleteness—are more than negative words. They are a condensation of both the “root” word meaning (positive) and the “no” prefixed word meaning that transform them into the ‘becoming ‘words for the paradoxical nature of time – one that “is” and one that “is not” simultaneously. As Heraclitus states, “We are and we are not.”.

When the outcomes of investments cannot be estimated in the initial stages, there is
uncertainty
in the economic environment. Two forms of
uncertainty
exist, namely, market

and technical
uncertainty

uncertainty
is exogenous to the investor (e.g., firm) and correlated with economic fundamentals. Technical
uncertainty
is endogenous and depends on the level of initial investment made.
Uncertainty
is dynamically evolving and thus affects the evolution of the value of the option through time.

The
uncertainty
refers to lack of certainty or a state of knowledge where it is impossible to exactly describe the existing state, a future outcome or inability to predict a situation like the effect of current pandemic (COVID-19).
