He wrote 30,000 separate mathematical equations to design the erection arch which were confirmed using some of Australia’s earliest computer systems and now form part of the @powerhousemuseum collection. The design and construction of this remarkable building is recorded in our collection of drawings, models and archival material. Image: Max Dupain. #sydneyoperahouse #joebertony」4月8日 15時18分
