Because the results we get when we calculate measurments are estimated or rounded up as some people say, so being around the true answer is called accurate. Also, the devices we use to measure ( scales are an example of this) are never actu...

Quantum mechanics has discovered that initial measurements are always uncertain and chaos ensures that uncertainties can overwhelm the ability to make prediction. Chance is often seen in terms of the limitations it imposes such as the lack of predictability.

Quantum mechanics implies that initial measurements are always uncertain, and chaos ensures that the uncertainties will quickly overwhelm the ability to make predictions. ... This is exactly the sense in which such systems are predictable: initial measurements contain information that can be used to predict future behavior.

Modeling work based on experimental measurements indicates that short-term depression of intracortical synapses provides a dynamic gain-control mechanism that allows equal percentage rate changes on rapidly and slowly firing afferents to produce equal postsynaptic responses.

Measurements are always uncertain for two reasons: First, measuring instruments are not always perfect and second, making measurements requires estimation. In making estimates on a scale such as the line scale found on a graduated cylinder, you must first become acquainted with the units on the scale.

Measurements are always intrinsically uncertain for the same reason. In quantum theory, mechanism is interrupted by this seemingly random 'collapse'. To see alternatives as shadow probabilities, even after something has happened, is counter to our subjective experience.
