In an interview with Jeremy Bernstein, given towards the end of his life and quoted in Bernstein's book, Bell reported being perplexed by the usual statement of the Heisenberg uncertainty or indeterminacy principle (x p, where x and p are the uncertainties or indeterminacies, depending on one's philosophical position, in position and momentum respectively, and is the (reduced) Planck 's constant).
Sa isang interbiyu sa Jeremy Bernstein, na ibinigay sa huli ng kanyang buhay at quoted sa Bernstein ng libro, Bell iniulat na naguguluhan sa pamamagitan ng karaniwang pahayag ng Heisenberg-aalinlangan o indeterminacy prinsipyo (x p, kung saan ang x at p ay ang uncertainties o indeterminacies, depende sa isa's pilosopiko posisyon, sa posisyon at momentum ayon sa, at ito ay ang (nabawasan) Planck 's tapat).
