What is ''faithful measurement'' in Quantum Mechanics exactly. I have seen this expression in Kochen-Specker Theorem.
In this case "subquantum element" is a supposed "hidden value".For such more general theories the KS theorem is applicable only if the measurement is assumed to be a faithful one, in the sense that there is a deterministic relation between a subquantum element of physical reality and the value of the observable found on measurement.
thanks for your reply. but again I cannot understand the exact definition of faithful measurement :/.Scott said:To quote wiki (http://en.wikipedia.org/wiki/Kochen–Specker_theorem:
In this case "subquantum element" is a supposed "hidden value".
Faithful measurement is a concept in science that refers to the accuracy and reliability of a measurement. It involves ensuring that the measurement process is free from bias and consistently produces similar results when repeated.
Faithful measurement is essential in science because it provides a basis for making valid conclusions and interpretations from data. Without faithful measurement, the results may be unreliable and misleading, leading to incorrect conclusions and potentially harmful decisions.
Some examples of faithful measurement in science include using precise instruments to measure physical quantities such as length, mass, and time, and calibrating the instruments to ensure their accuracy. In experiments, faithful measurement can be achieved by controlling variables and eliminating sources of bias.
Scientists can ensure faithful measurement by using standardized procedures and protocols, calibrating instruments, and taking repeated measurements. They should also be aware of potential sources of bias and take steps to minimize their impact on the results.
Not having faithful measurement in science can lead to inaccurate and unreliable results, which can have serious consequences. It can result in incorrect conclusions and interpretations, which can hinder scientific progress and potentially harm the environment or human health.
