Accuracy is a desirable aspect which is conceptually well defined. There are some definitions available for ‘accurate measurement’ in the ISO vocabulary of metrology terms. According to them, a ...

What is the meaning of Heisenberg’s analogy? (Courtesy: German Federal Archives) A row has broken out among physicists over an analogy used by Werner Heisenberg in 1927 to make sense of his famous ...
