Derivation of heisenberg uncertainty
Web1 Answer. It is a basic postulate of quantum mechanics. It states that it is impossible simultaneously to measure the position of a particle, say an electron, an atom or a molecule, and its momentum. It places limits on these measurements such that uncertainty in position Δ x and momentum Δ p is given by Δ x Δ p ≥ ℏ / 2 where (hbar) ℏ ...
