The story
The Sydney Opera House sails were nearly impossible to build until someone cut an orange. If every sail is a piece carved from the same imaginary sphere, they all curve the same way and can be made from repeated parts, like peel segments from one fruit.
What you'll learn
- Shapes cut from one sphere all share the same curve.
- Repeating one curve means builders can reuse the same moulds and parts.
- The Opera House design took years until the sphere idea solved it.
- Quarky takeaway: a hard problem can crack open with one simple idea.
