Synchronisation of 5 coupled metronomes done in Lancaster University, Physics Dep, Nonlinear dynamics and medical physics group.

Some explanation by 'shoonya' which I think is pretty good:
Here you go: metronomes (or "pendula") when on table, oscillate with random phases, since that is how they started and they are "uncoupled" (no energy/information flows from one to other so they do not "know" each other.) When they are all together on the cans, notice that the cans themselves oscillate little, providing coupling/information crossover. which forces "synchronization" in periodic systems (discovered by Huygens in 17th century).
A useful book: "Synchronization: A Universal Concept in Nonlinear Sciences " by Arkady Pikovsky, Michael Rosenblum and Jurgen Kurths.

| Shouldn't it be pendula, not pendulums? |

| when the pendulums were put on the cans, they started to go in sync. |
