Pronunciation: [ˌɪndɪtˈɜːmɪnənsi pɹˈɪnsɪpə͡l] (IPA) 
The uncertainty principle, also known as the indeterminancy principle, is a fundamental concept in quantum mechanics. It states that the more precisely you measure the position of a particle, the less precisely you can measure its momentum, and vice versa. The principle is often described using terms such as indeterminacy, indeterminateness, and unpredictability. In addition, the principle is sometimes also referred to as Heisenberg's uncertainty principle, after German physicist Werner Heisenberg who first proposed it. Other synonyms for the uncertainty principle include the Heisenberg uncertainty principle, the uncertainty relation, and the complementarity principle.
