Input (English): Robertson generalized this statement to any Hermitian operators. One attempted refutation of this statement concerns letting a photon escape, then re-weighing a box named after Einstein. This theorem sets one side equal to the reduced Planck's constant over two, which is less than or equal to the product of a certain function applied to two (*) non-commuting variables, like energy at time. For ten points, identify this theorem, one formulation of which states that both position and momentum of a particle cannot be known simultaneously, formulated by Werner Heisenberg.
Output (English): Science
