"Sailing is nothing else but walking on the waters from one place to another. This road differs from those on Earth in three things. That of the Earth is firm, this flexible, that of the earth remain, this movable, that of the designated Earth and that of the sea unknown ".
Martín Cortés de Albacar, "Breve Compendio de la Sphera y del Arte de Navegar, con nuevos instrumentos y reglas, ejemplarizado con muy sutiles demostraciones" (Sevilla, 1551)
"The engineering of complex cyber-physical systems, quite unlike other areas of engineering, is a work of high uncertainty (as business creation and navigation in the 16th century). Therefore, practices that reduce product and process uncertainty (self-organized teams, product list, short cycles, quickly learn with the customer, simple design, automation, etc) should be employed. Do not attempt to copy all processes and practices from other areas of engineering. It's more art and architecture than engineering. "
