10/05/2019 – Call for Proposals: 25th AISNA Biennial Conference in Ragusa

This 2019 marks the 500th anniversary of Leonardo da Vinci (1452-1519), the universal genius, the twofold engineer of defense walls against the enemy as much as swing-bridges for overtaking them; of impenetrable dams for stopping natural waterways as much as artificial water-channels for the penetration of commerce and the mixing of peoples and cultures; of barricades for puzzling the enemy on the ground as much as flying machines and futuristic prototypes of inspection drones, anticipating our transcontinental connections.
