noaniqlik prinsipi– Heisenberg tomonidan ishlab chiqilgan, kvant mexanikasi tamoyiliga ko'ra, ikki bog'liq, kuzatiladigan miqdordagi biri aniqlik, momentum yoki energiya va vaqt sifatida aniqlanishi, ikkinchisining o'lchovida noaniqliklar keltirib chiqaradi, shuning uchun ham ikkala tomonning noaniqliklari miqdori h / 2 p dan teng yoki undan katta bo'lsa, unda plankning doimiyligi teng.

uncertainty principle– the principle of quantum mechanics, formulated by heisenberg, that the accurate measurement of one of two related, observable quantities, as position and momentum or energy and time, produces uncertainties in the measurement of the other, such that the product of the uncertainties of both quantities is equal to or greater than h/ 2 π, whereh equals planck's constant.
