WebbMeasurements can be made of position x of a particle and the x -component of its linear momentum, denoted by px. These two observables are incompatible because they have different state functions. The phenomenon of diffraction noted above illustrates the impossibility of measuring position and momentum simultaneously and precisely. WebbParticipants. Ruediger Schack Mathematician.
