A World of Maths: Barcelona's Big Church

The video explores the Sagrada Familia, a cathedral in Barcelona designed by Antoni Gaudi. It discusses the ongoing construction, architectural details, and the use of mathematical and geometric principles in its design. The video highlights the challenges faced due to the loss of Gaudi's original plans and the role of model making in reconstruction. It also covers the use of 3D modeling software in construction and the importance of mathematics in Gaudi's work.
