Yes Rong Youying is the founder of Math Bridge. Rong Youying made a Newton Math Bridge with 388 nails and got a doctorate. Mathematics Bridge, also known as Newton Bridge, is a wooden bridge across Jianhe River at Queen's College, Cambridge University. The whole bridge is made of wood of different sizes, and there are 10299 interfaces in the bridge. If an interface is calculated with one nail, then at least the same number of nails are needed. It's amazing that Newton Bridge didn't use nails.
