Da Vinci's Purposeful Mistakes

puppetman writes "According to a story out today, Leonardo Da Vinci deliberately introduced mistakes in his inventions. The series, Leonardo, produced by the BBC, claims that simple mistakes were introduced; mistakes that would not become apparent until after the contraption was built. The series hypothesizes that this was either a form of patent protection, or a way of ensuring his work did not end up being used for military purposes (Da Vinci was a gay, vegetarian pacifist)."

      The degree of his pacifism is also quite suspect:

      1482 saw him writing to the Duke of Milan, Ludovico Sforza listing his capabilities as a designer of both civil and military machines. Italy was being afflicted by wars between the various city-states; this was followed by a French invasion. This was a time of rapid development of firearms and explosives and military engineers were important figures. Leonardo's had many ideas for fortifications, bridges, weapons, and river diversions to flood the enemy.

He designed numerous weapons, including missiles, multi-barreled machine guns, grenades, mortars, and even a modern-style tank. He drew the line, however, with his plans for an underwater breathing device, which he refused to reveal, saying that men would likely use it for "evil in war."
