Molecule Viewer: a long way down

moleculeviewer.org Visit website

Editorial interest 84/100 Selection signal · not a rating of the site

An interactive 3D viewer for exploring molecules, then zooming through atoms, nuclei and protons toward the Planck length.

Landing page captured for the 2026-10-20 issue.

For: Students, educators, and curious readers exploring molecules and the scale beneath them
Worth noticing: The electron-cloud display uses hydrogen-like orbitals scaled by Slater’s rules, which the site identifies as a textbook approximation.

Field notes

The interface offers a guided tour as well as independent exploration, with keyboard shortcuts and controls for measuring distances and angles. The molecule library searches elements and PubChem’s compounds, and the page attributes its structures to PubChem 3D conformers. Its electron-cloud view is explicitly an approximation using hydrogen-like orbitals scaled by Slater’s rules, rather than a full quantum calculation.
