Cube core mechanism and atomic clock: what they have in common

1. Step 1. Cube core mechanism — is part of — Rubik’s Cube. The central mechanism with axles.
2. Step 2. Rubik’s Cube — uses — Algorithm. Solved with algorithms.
3. Step 3. Algorithm — includes — Dijkstra’s algorithm. An algorithm.
4. Step 4. Dijkstra’s algorithm — is used in — Online maps. Routes.
5. Step 5. Online maps — uses — GPS (satellite navigation). The position.
6. Step 6. GPS (satellite navigation) — uses — Atomic clock. The satellites carry atomic clocks; the position is calculated from signal arrival times.
