NANOPHAGE RESEARCH / INITIAL CONDITIONS

Set the conditions.

Six starting points. One particle engine. Every force is adjustable.

The current system is preserved as a checkpoint.

OPERATOR FIELD GUIDE / 02

A particle physics sandbox.

nanoEngine explores how simple forces produce intricate motion. Begin with the original five-particle system, or investigate a larger field.

The original interaction. Particles repel below the equilibrium distance and attract above it. Strength changes the force magnitude; power changes its shape; cutoff limits its reach. Negative strength reverses the interaction. The force graph updates as you work.

Set the motion. The thermostat steers RMS speed toward its target. Damping removes motion; flow and swirl redirect it; noise adds random impulses. Turn off motion drivers to explore pair interactions on their own. Optional disk collisions exchange momentum with adjustable restitution.

Intervene. Grab and throw particles. Paint with Add or Erase. Pull, push, kick, or stir with the force brushes. Place fixed attractors or repulsors from Forces. Use Inspect to edit an individual particle's mass, pin it, or stop it.

Observe and compare. Switch between trajectories, velocity, force, and flow. Adjust trace duration and colors in Display. Save a checkpoint, change the system, then return to try another intervention. Export JSON for exact physics state; export PNG to keep the trails.

Controls. Keys 1–9 select tools, Space pauses, and + / − zoom. Scroll or pinch to zoom; Pan moves the view. On the focused canvas, arrows move the tool cursor and Enter applies the tool. With Grab, Enter picks up or releases a nearby particle. Escape cancels field placement or closes a dialog.

About the model. This is a classical 2D particle-dynamics sandbox with an adjustable force law, using simulation units. It is not a model of subatomic particles. It uses fixed 60 Hz updates with two substeps; disk collisions use discrete impulses. Very fast or densely packed disks can overlap. Time pauses in hidden tabs and open dialogs.
