The concept behind Maths in the City is to capture and highlight the math behind everyday objects you see and use in your city. It could be an oddly shaped building, a garden with creative topiaries or an unusually windy bike path and then of course you have to explain the application of math in your example. The competition is open to individuals or groups from anywhere in the world. The deadline for submissions is May 3, 2011 at noon (British Summer Time) and finalists will be contacted by May 31, 2011.
