Uncertainty Principle

According to Stanford Encyclopedia of Philosophy “the notion of ‘uncertainty’ occurs in several different meanings in the physical literature. It may refer to a lack of knowledge of a quantity by an observer, or to the experimental inaccuracy with which a quantity is measured, or to some ambiguity in the definition of a quantity, or to a statistical spread in an ensemble of similarly prepared systems”. It is stated that “Heisenberg and Bohr did not decide on a single language for quantum mechanical uncertainties. Prevention is discussed about which name is the most appropriate one in quantum mechanics, we use the name ‘uncertainty principle’ simply because it is the most common one in the literature”.(Stanford Encyclopedia of philosophy)
“The uncertainty relations have to do with the measurement of these four properties; in particular, they have to do with the precision with which these properties can be measured. Up until the advent of quantum mechanics, everyone thought that the precision of any measurement was limited only by the accuracy of the instruments the experimenter used”. (American Institute of Physics) Also it is shown that “Heisenberg showed that no matter how accurate the instruments used, quantum mechanics limits the precision when two properties are measured at the same time. These are not just any two properties but two that are represented by variables that have a special relationship in the equations”.
