According to the uncertainty principle, and the illustrations below... Fig. A illustrates a situation where the position is precisely determined and the momentum unknown, and Fig.B illustrates a situation where the position undetermined and the momentum reasonably well known. Fig. A illustrates a situation where both the position and the momentum are determined with similar uncertainty, and Fig.B illustrates a situation where the position and momentum are undetermined. Fig. A illustrates a situation where neither the position nor the momentum are determined, and Fig.B illustrates a situation where the position and momentum are undetermined. Fig. A illustrates a situation where the position is undetermined whereas the momentum is precisely known, and Fig.B illustrates a situation where the position is well determined and the momentum unknown.+
