Two giant advertising billboard signs have been given over to exhibit a piece of art based on a vital, but little known physics equation.
The artwork appears as a 'dazzling little troupe of dancing characters' against a 'motorway blue' backdrop, and beams down on motorists and pedestrians as they make their way through West London for 14 days this November. Written in the international language of mathematics, it depicts quantum physics' Schrödinger equation.
