Molecule Viewer

Everything is made of
something smaller.

Start with something you could hold in your hand. Zoom in, and keep zooming: molecules, atoms, the particles inside them, down to the smallest length physics can name. Thirty-two powers of ten.

Getting around

Drag: Turn the view
Scroll or pinch: Zoom. Keep scrolling in to enter an atom, its nucleus, a proton, and finally the Planck length
Double-click an atom: Zoom into that atom
Click atoms: Measure: two give a distance, three an angle
Enter / Esc: Zoom in a level / out a level
← →: Previous and next molecule
1–4: Clouds, ball and stick, space filling, skeleton
/: Search elements and PubChem's 100 million compounds
E Q R: Periodic table, particle zoo, surprise me
L Space T P: Labels, spin, random tour, save picture
[ H: Fold the library away; hide everything but the view
