Of the many structures Leonardo da Vinci designed, perhaps none made more ingenious use of materials than his practical design for an easy-to-assemble, self-supporting bridge [read more: [📹

Excuse me, this structure was first invented by ancient Chinese carpenter master Lu Ban, thousands years ago. There are many existing ancient bridges around China today. Cheers

This is a reproduction of the bridge in the da Vinci exhibit in Venice.

In China village, it is common.

This proofs that you (initially) do not need deep knowledge of physics (statics) to start designing. You can be creative without being weighed down by rigorous math. But, after the initial design is completed math & physics are necessary to verify it for functionality & safety.

I thought this design was documented in Roman military writings

Leonardo da Vinci is first known time traveler.

That's awesome 🤯
