Birth of Leonardo da Vinci

Leonardo da Vinchi was born in April 14, 1452. He had many skills but was especially talented in metal crafting, painting, and learning new skills quickly. He accomplished many things over his lifetime but he was especially known for his paintings and drawings. We have also now learned from his notebooks how many things he invented and scientific discoveries he found.

Fall of Constantinople

The fall of Constantinople on May 29, 1453 ended the Byzantine empire and marked the end of 10 years of war. It was defeated by the Ottomon Turks.

The telescope

Leonardo da Vinci made a design for what we now call the telescope and he also made a few discoveries with the telescope about astronomy but once we looked into it we saw that much of what he believed was incorrect.

Autopsy

Leonardo da Vinci dissected his first body when he was 20 years old for science and art. He studied many things about the human body like how it moved with muscles and joints and the organs and lungs.

thee self-propelled cart

Leonardo da Vinci made a design of a self-propelled cart that moved on its own. What would happen is there is a cam a shaped piece of metal or wood and the cam rotates and turns the stearing wheel to turn the cart.

3 barreled cannon

Leonardo da Vinci invented a 3 barreled cannon because it was easy to use and was more accurate because it shot in 3 directions not one. Also he made it because it's light so people can carry it not like a cannon where 3 people had to fire it.

Discovering that the earth is not the center of the universe

Leonardo da Vinci was so curious about the nature and life of the solar system that he researched it for a long time. In his notes he said that the earth is not the center of the univese though that's what people believed in back then. So Leonardo said the sun doesn't move; we move around it but people didn't believe him.

Helicopter

Leonardo da Vinci made a design for the now called helicopter. He called it the Aerial Screw. He never built or tested the Aerial Screw after he made the design and it's probably a good thing he didn't because now, we would know that if we used all of the extremely heavy things he did, it wouldn't fly.

circa. 1483 to circa. 1486

The anemometer

Leon Battista Alberti made the anemometer in 1450.  The anemometer scales how much wind power there is. Leonardo da Vinci made another anemometer that is easier to use and more accurate with a peice of wood showing how much wind there is.

Leonardo da Vinci's geology work

Leonardo da Vinci found out that the earth has been here for a very long time before humans. He knew this because he found shells and other things from the ocean at high places which he thought meant that the sea level must have been up there in the past. So he thought it would take a very long time to make the sea level go so much lower than back then.

The parachute

Jean Pierre Blanchard made the first working parachute in 1783. Jacques Garnerin was able to make a successful descent with a parachute from 3,000 feet in 1797. Leonardo made the design of the parachute in 1483, approximately, and expected it to be improved.

circa. 1489

the human anatomy

Leonardo da Vinci made an extremely accurate drawing of a human skull to see the skull and teeth and he also drew another showing a cavity in a tooth. How he got such an accurate drawing was he dissected multiple people and looked at their skull.

Discovery of sound waves

Leonardo da Vinci made a theory that sound moves in waves. Also it helped that he was a musician which helped him to identify sounds.

Columbus discovers North America

After sailing across the Atlantic Ocean, Italian explorer Christopher Columbus sights a Bahamian island. He found North America and thought it was Asia. This was not good for Italy because the Eruopians then used North America to trade as well as Italy so Italy got less money and materials.

Pulley system

Leonardo da Vinci made a pulley system. It involved weight and friction to make it work. Leonardo da Vinci made the first systematic study of friction.

1494

the Italian war

The Italian Wars started in 1494 when the French attacked the Italians who had big walls but the French had better cannons which were faster to reload and easier to use. So they brought down Italy's walls very quickly. The Italians were not ready because they had outdated cannons so they didn't think that they would have so much better cannons then they did so they thought they had more time then they did.

The mechanical knight

Leonardo da Vinci made a knight with springs or a waterwheel. the knight could stand, sit, raised it's visor, and lift it's arm. Now there has been a modern reconstruction made by Mark Rosheim.

circa. 1497

Ball bearing

Leonardo da Vinci made and used something called a ball bearing and it makes something be able to turn without friction so like a wheel has bearings or the top part of a tank that spins 360 degrees. Leonardo used these bearings for many of his inventions. Also ball bearings stop friction so for example a figit spinner it spins so well and for so long because of ball bearings.

Bonfire of the Vanities

Girolamo Savonarola took over Florence and didn't like Lorenzo il Magnifico's work so all of Florence made a bonfire of paintings, cosmetics, art, and books and other objects. He wanted to turn back the clock on scientific development, among other things.

The Venice clock tower

The Venice clock tower was one of the most complex mechanisms because it told the time, showed the phases of the moon and showed the constellations in the sky and also had robots (automata). Leonardo da Vinci was visiting Venice when the clock tower was unveiled.

The Parabolic Arch

Leonardo da Vinci made a design called the parabolic Arch or you could call a self sustaining bridge. We actually discovered the notes centuries later then built and tested the parabolic bridge.

circa. 1500

Clocks

Leonardo da Vinci didn't make the clock but improved the clock from what it was. He maade a clock with minutes and hours. Also he used springs instead of weights. 

Leonardo Allen-Felluga
circa. 1500

Scuba gear

Leonardo da Vinci invented scuba gear but for attacking from the water not for under sea exploration which we now use scuba gear for. He also thought it would be a very effective way to sabotage enemy ships.
