WebOct 8, 2001 · 2.1 Heisenberg’s road to the uncertainty relations. Heisenberg introduced his famous relations in an article of 1927, entitled Ueber den anschaulichen Inhalt der quantentheoretischen Kinematik und Mechanik. A (partial) translation of this title is: “On the anschaulich content of quantum theoretical kinematics and mechanics”. 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 ...
