Magic Square Cathedral
The Sagrada Familia cathedral in Barcelona designed by Antoni Gaudí is a mathematician’s dream. Hyperbolic paraboloid structures are featured throughout. Have you eaten Pringles? Then you definitely know what a Hyperbolic paraboloid structure is. Catenary arches (a geometric curve) abound. The cathedral also contains a Magic Square — an arrangement of numbers that equal the same amount in every column, row, and diagonal. The magic number in Sagrada Familia’s case is 33, which alludes to multiple religious symbols. For example, Jesus performed 33 recorded miracles, and most Christians believe he was crucified at 33 years old in 33 A.D.
