with Johnny Ball
A lighthearted exploration of science and number.
This week Johnny finds out how to be a builder without dropping bricks, and studies the stresses of structures and skyscrapers, buttresses and birdcages.
So it's Up and Over from the gothic to the geodesic - a constructive look at the arch in architecture.
