Finding a particle depends on space and time. Each surface represents a probability threshold, with red indicating the largest values and blue the smallest. Note that “isolated” blobs of red form in the 3D visualization.
How do you depict the complex 3D structure of this plot? In this version, the surface has been made transparent. Click the image to contrast it with an alternate version, which uses a solid surface with a cut-out and slices to show the internal structure.
