Possible paths to connect I with F.

Fig. 2.

Schematic representation of the sum of amplitudes for a finite set of trajectories connecting initial and final states. Every vector corresponds to every function x(t) connecting I with F. All of them are unit vectors and form an angle S/ħ with the positive x-axis. Some vectors were selected, and the sum was done using the tail-to-head method. Only trajectories near the classical one contribute coherently to the sum (red straight line). See text for more details.

Transition between quantum (top) to classical behavior (bottom) in the double-slit experiment. The screens show the simulation of the double-slit exercise using Modellus. Observe how the distances between maxima and minima are reduced, making the interference pattern disappear, as the mass is increased (top, middle, and bottom panels, respectively).
