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...

In the third lecture, we'll discuss ways to recognize, estimate and report the errors that are always present in measurements. ... the digit read between the lines is always uncertain...

Inversely obtained hydrologic parameters are always uncertain (nonunique) because of errors associated with the measurements and the invoked conceptual model, ... We explain the above concepts using an example in which two municipal solid waste incinerator bottom ash monofills were successfully calibrated and tested for flow,

A number if incidents unexplainable in any rational terms have changed the whole course of history. Quantum mechanics has discovered that initial measurements are always uncertain and chaos ensures that uncertainties can overwhelm the ability to make prediction.

Chemistry helps to explain the world we live in by describing the changes that matter undergoes as a result of chemicals interacting. ... 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...

Our inequalities are necessary conditions for the existence of a local realistic description of projective measurements on qubits. ... Then I will explain the relation between MUBs and Hadamard matrices, and report on a search for MUB-sets in dimension N=6. In this case no sets of more than three MUBs are found,

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.

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.
