Leonardo's fascination

with machines probably

began during his boyhood.

Some of his earliest sketches

clearly show how various

machine parts worked.

For example, water wheels

turned millstones to grind

grain and Archimedes' screws

lifted water from streams

providing a ready supply

for drinking and washing

• Leonardo set out to write the first systematic explanations of how machines work and how the elements of machines can be combined.
• They include :
• The jack, the same device that you use today to change a tire
• Roller bearings, a ball-bearing driven axle that is extremely similar to what cars use today
• The one-man printing press
• Mechanical transmissions, i.e. the gear system used in everything from ten-speeds to automobiles
• The odometer

• In addition : a series of scientific instruments for measuring everything from tensile strength to humidity.

• Da Vinci nevertheless envisioned a series of inventions that would eventually be used in the modern world, sometimes with only minor changes to his original designs, including the helicopter, the hang-glider and the machine gun.

• Leonardo collected his technological innovations in notebooks called codeci . One of the best preserved is the Codex Leicester

• Leonardo produced a drawing of a single span 720-foot (240 m) bridge as part of a civil engineering project for Ottoman Sultan Beyazid II of Istanbul. The bridge was intended to span an inlet at the mouth of the Bosporus known as the Golden Horn.

Leonardo's vision was resurrected in 2001 when a

smaller bridge based on his design was constructed in Norway.

• Golden Horn" bridge built on October 31, 2001 in Oslo, Norway

• A Short List of his Inventions  
• He sketched the first parachute
• The first helicopter
• The first airplane
• The first tank
• The first repeating rifle
• A swinging bridge
• A paddle boat
• The first 'motor' car
• A machine for testing the tensile strength of wire
• A calculator
• A double hull for ships and boats
