I am promoting discussion about the question
What is a uncertainty in Science?
Uncertainty is definitely linked to probability.
Probability is a definite number (one number) between 0 and 1
So it is tempting to think that if the probability is p then the uncertainty can be defined as (1-p), but this doesn't really work.
Consider a cubical shaped object.
What is the uncertainty of position when I place it along a line?
Let my cube be a model of my car and of side L.
