a story begins inside an atom.

URANIUM–235 / A CLOSER LOOK

235 particles.
One nucleus.

235 particles, bound together by the strong nuclear force. This is where our story begins.

AT THE THRESHOLD

One neutron
is enough.

Drag the neutron into the nucleus. Or select it. The next moment is yours.

A conceptual uranium-235 nucleus, containing 92 protons and 143 neutrons. Scroll or use the exploration buttons to move closer. Drag with a mouse or use arrow keys to rotate. Space pauses motion. Home resets the view. Colors, positions, motion, and atmospheric motes are illustrative, not a physical simulation.

NUCLUME / CHAPTER 01

A world within.
A world ahead.

From a single atom to an entire city. NUCLUME is an exploration of the science behind nuclear energy. This first chapter begins with the nucleus of uranium-235.

Its 92 protons define it as uranium. Add 143 neutrons and you have 235 nucleons, giving this isotope its name.

This is a conceptual model, not a physical simulation. Colors identify particle types; positions, sizes, spacing, and motion are illustrative. The ambient motes are atmosphere, not emitted particles. Electrons are outside this view.
