Particle in a 1-D box can be thought of confining the particle moving a long a string, confined by the two ends of the string. 2-D PIB confines the particle's motion on a plane, confined by the rectangular perimeter. 3-D PIB confines the particle's motion in a real box. For those three cases, we can find geometry analogues in real life. Now, let's tackle a hypothetical 4-D PIB model. The four dimensions have variable x, y, z, and w, respectively...
