I just read up on this shit myself a few days ago, so hopefully I'll learn something more with this thread myself.

no not him, he's a TMN turtle... dumbass :D


no not him either, he's just one of them faggy Hollywood actors


this dood


probably most famous for painting this


Here's a short wiki bio
http://en.wikipedia.org/wiki/Leonardo_da_Vinci

Although he is and was renowned mainly as a painter, he also conceptualized a helicopter, a tank, concentrated solar power, and a calculator, amongst other shit.

We'll take a look at war machines first, before moving on to flying machines, architecture, and various others later on.

Todays invention: 33-Barreled Organ
The way Leonardo da Vinci saw it, the problem with the canons of the time was that they took far too long to load. His solution to that problem was to build multi-barreled guns that could be loaded and fired simultaneously.

This idea forms the basis of war inventions like da Vinci’s 33-barreled organ, which featured 33 small-caliber guns connected together. The canons were divided into three rows of 11 guns each, all connected to a single revolving platform. Attached to the sides of the platform were large wheels.

All the guns on the organ would be loaded and then, during battle, the first row of 11 would be fired. The platform would then be rotated to properly aim the next row of canons. The idea was that while one set of canons was being fired, another set would be cooling and the third set could be loaded. This system allowed soldiers to repeatedly fire without interruption.
The weapon is referred to as an "organ" because the rows of canon barrels resemble the pipes of an organ. Leonardo da Vinci’s design for the 33-barrelled organ is generally regarded as the basis for the modern day machine gun – a weapon that didn’t really develop for commercial use until the 19th century.

It was in 1346 that the English first used cannons which, propelled by exploding gunpowder, fired stone balls. Despite this, progress in that area of military weaponry was not fast and it was here Leonardo particularly applied his thinking. This was an area in which there was plenty which could be done to improve the weaponry.
A typical cannon of Leonardo's age was cast iron or bronze, had a short barrel, a short range and fired cannonballs which fitted very approximately. The first thing we know Leonardo did was to design breech-loading cannons as against muzzle-loading. They required a fast means of being cooled before another firing and Leonardo calculated that a vat of water would do the trick. By using several cannons in rotation you could be firing one, loading another and cooling the third.
Leonardo was the first to measure the penetrating power of a missile, and to ascertain how to vary it by changing the attitude. During these tests he even managed to launch a rocket-powered cannon-ball ten thousand feet into the air.
The steam cannon was another experiment. To be manufactured from copper, the breech of the canon would be built into a brazier of burning coals which would heat it to very high temperatures. Following this, a small amount of water would be injected just behind the iron ball. When the water turned to steam it would drive the ball out under pressure. Given that Leonardo even quoted how large a cannonball this weapon could fire, and how far it would travel, it is quite feasible that this weapon was actually built and test-fired.
He wanted to increase the rate of firing weapons and so designed machines with multiple cannons, so they could be fired successively or all together. Many people consider these the forerunner of the modern machine gun. Two of these used racks of eleven or fourteen guns. While the top row was being fired the next rack was loaded; at the same time, a third rack was cooling off. Another design had the guns in a triangle spread for greater distribution of the projectiles.
Leonardo also wanted to have more effective projectiles. In attempting to do this he designed shells filled with gunpowder which exploded upon impact; others contained projectiles which would scatter over the area. One design sees a large ball split into two pieces as it leaves the mortar. This sends smaller balls in all directions and they, in turn, explode upon contact.
But better projectiles and guns are of little use without a more efficient system of igniting the gunpowder. Leonardo can claim to have invented the wheel-lock, a system which was much more reliable, (and much more expensive) than the flintlock. Centuries after Leonardo's death armies would adopt his system.
And now you have your improved ignition system you also need improved gunpowder. Leonardo had favourite recipes for this, including one which had the ingredients dampened and then sun dried.
One of Leonardo's most famous drawings is that of a cannon foundry. It shows the manpower, levers, pulleys and tackle required to manipulate the heavy cannons of his time. All the activity in this drawing revolves around the act of placing the cannon onto the gun carriage.

Tic Toc, Tic Toc
Da Vinci was beyond talented, not to mention a self made genius with an IQ of 180+
I watch a few documentaries on him that were incredible. Unfortunately I'm not sure whether to fear his work, or be marveled..

2. THE GIANT CROSSBOW


One thing Leonardo da Vinci may have understood better than any of his contemporaries was the psychological effects of weapons in warfare. Da Vinci knew that the fear weapons could instill in enemies was just as important (if not more so) than the damage they could actually inflict.
This was one of the main ideas behind many of da Vinci’s war inventions – among them, his giant crossbow. Designed for pure intimidation, da Vinci’s crossbow was to measure 42 braccia (or 27 yards) across. The device would have six wheels (three on each side) for mobility, and the bow itself would be made of thin wood for flexibility.


Rather than fire giant arrows, Leonardo’s crossbow instead seems to be designed to fire large stones or possibly flaming bombs. For use, a soldier spins a crank to pull back the bow and loads the artillery. The soldier would then use a mallet to knock out a holding pin and fire the weapon.
The giant crossbow invention is a great example of the way da Vinci’s artwork really brought his ideas to life. Through his illustrations, an idea, however improbable, becomes realistic and plausible. His vivid drawings of the giant crossbow invention also make it clear the idea behind the impressive weapon was to terrify enemies into fleeing rather than fighting.

3. Armoured Car

The precursor to the modern tank, Leonardo da Vinci’s armored car invention was capable of moving in any direction and was equipped with a large number of weapons. The most famous of da Vinci’s war machines, the armored car was designed to intimidate and scatter an opposing army.

Da Vinci’s vehicle has a number of light cannons arranged on a circular platform with wheels that allow for 360-degree range. The platform is covered by a large protective cover (much like a turtle’s shell), reinforced with metal plates, which was to be slanted to better deflect enemy fire. There is a sighting turret on top to coordinate the firing of the canons and the steering of the vehicle.

The motion of the machine was to be powered by eight men inside of the tank who would constantly turn cranks to spin the wheels. Leonardo suggested in his notes that the thought of using horses for power crossed his mind, but he dismissed it because he feared the animals would become too unpredictable in the confines of the tank.
Despite its elaborate design, da Vinci’s tank has a major flaw - the powering cranks went in opposite directions. This made forward motion impossible. Scholars suggest such a basic engineering flaw would never have escaped the detail-oriented mind of Leonardo da Vinci, and that he may have inserted the flaw intentionally. A pacifist at heart, da Vinci might have sabotaged his own design to discourage the war machine from every being built.


Leonardo probably drew this model of a war machine for a presentation to Ludovico il Moro, “The Moor”, Duke of Milan, around 1485. The drawing in the original manuscript therefore appears neat and well laid-out.
The armoured car, like other inventions such as the scythed chariot, has a classical pedigree. Like other Renaissance artist-engineers, Leonardo looked to the classical world for inspiration. He would then go beyond classical models and devise his own solutions.
Leonardo’s armoured car contained many light cannons. These were arranged on a circular platform which was based on four wheels and provided a firing range of 360 degrees. The whole platform was surrounded by a conical cover with a sighting turret at the top. At the centre of the car, two cranks were used to set the machine in motion.
The project is technically unrealisable and the drawing also contains a mechanical error which prevents the car from functioning – the cams as drawn would turn the wheels in opposing directions. But this is a demonstration piece, not a working drawing for technicians.
Many consider this armoured car as the precursor to the modern tank.
