sophia collection jewelry wholesale Da Vinci's achievements in various fields ??

famili ultrasonic jewelry cleaner wholesale 1. Astronomy. Da Vinci holds a negative view of the traditional "Earth Center". He believes that the earth is not the center of the solar system, nor the center of the universe, but just a planet that runs around the sun. The sun itself is not sporty. Da Vinci also believes that the moon is not glowing, and he just reflects the glory of the sun. His point of view was earlier than Copernicus's "Sun Center". Even at the time, Da Vinci fantasized with solar energy.

2, physics. Da Vinci re -discovered the concept of liquid pressure and proposed the principle of connectors. He pointed out: In the connected device, the height of the liquid surface of the same liquid is the same, the height of the liquid surface of different liquids is different, and the height and density of the liquid are inversely proportional. He discovered the principle of inertia and later proved to Galileo's experiments. He believes that a ejection body initially rises along the tilted line, and the curve displacement is shifted under the mixed action of gravity and impulse, and finally the impulse is exhausted. His discovery shakes Aristotle's fall theory. He developed the principle of leverage, and in addition to pushing the relationship between the force and the length of the arm, there was a relationship between speed and arm length. He pointed out the impossible possibility of "permanent motivation" as energy. Da Vinci also foreshadowed the atomic principles of the material, and vividly described the power of atomic energy: "That thing will burst from the ground, ... it will suddenly die in the silent atmosphere, and the castle will be completely destroyed. It seems to have destructive power in the air. "

3, medicine. Da Vinci has also achieved great achievements in anatomy and physiology, and is considered the ancestor of modern dissection of modern biological anatomy. He mastered human anatomy knowledge, started with anatomy, and studied physiology and medicine. He first used wax to express the internal structure of the human brain, and was also the first person to make heart and eyes with glass and ceramics. He discovered the function of blood, thinking that blood plays a role in metabolism on the human body. He said that the blood continued to transform the whole body, bringing the nutrients to all parts of the body, and then taking away the waste in the body. Da Vinci studied the heart, and he found that the heart had four cavities and painted the heart valve. He believes that one of the causes of the elderly is arteriosclerosis, and the cause of arteriosclerosis is lack of exercise. Later, William in the UK. Harvey confirmed and developed these physiological achievements of Da Vinci.

4, building. In terms of architecture, Da Vinci shows outstanding talents. He has designed bridges, churches, round roof buildings and urban sewer. In the design of urban streets, he separated the car and horse roads from the sidewalk; when designing urban buildings, he specifically stipulated the height of the house and the width of the street. Milan's moat was designed and built.

5, water conservancy project. Da Vinci's research on water conservancy was one century earlier than the Italian scholar Chystel. In order to exclude sediment, he made a construction plan to unblock the Ano River. He designed and personally presided over the construction of the canal irrigation project from Milan to Pavia. Some reservoirs, sluks, and dams built by him have facilitated farmland irrigation and promoted the development of agricultural production. Some water conservancy facilities are still playing.

6, military and machinery. Da Vinci's research and invention also involved military and machinery. He invented flight machinery, helicopter, parachute, machine guns, grenades, tank vehicles, submarines, double -layer shell warships, cranes, and so on.

7, geology. Da Vinci inferred that the crust has changed according to the fact that the animal fossils in the sea are on the mountains, pointing out that the traces of floods on the earth are proof of the changes in sea and land. This idea is quite similar to Herdon's foundation in geological science 300 years later. And before Magellan's sailing worldwide, he calculated that the diameter of the earth was more than 7,000 miles.
. He also made significant contributions in the field of mathematics and water conservancy projects. It can be said that Da Vinci's research involves every department of natural science, and his thoughts and in order to go deep into all areas of human knowledge. He is a rare scholar in the world. However, most of Da Vinci's works and manuscripts were not published until he was discovered by the world for many years after his death. Scientific historian Danpier commented on Da Vinci like this, "If he published his work at the beginning, science would definitely jump to a hundred years later."

8, he is the helicopter of the helicopter Ancestor
The genius during the Renaissance may start the history of human flight before the Wright brothers.
"If he published his work at the beginning, science will definitely jump to a hundred years later. It is certainly useless to guess this situation is useless to human academic and society. We can say that if this happens, the evolution of human academics and society will definitely be very different, "the scientist Danpier's talked about this scientific giant is Da Vinci.
In fact, the people of the Da Vinci era also have a dream of flying. After staying in Florence for a while, Da Vinci came to Milan again. From 1483 to 1486, Da Vinci drawn a sketch of a flight device.
In Da Vinci's idea, this is a aircraft that relies on the pilots to drive the motivation to drive. The genius called his design as a "fluttering aircraft", and Da Vinci made his aircraft have the driving force and improvement.
Ne, let's take the plane according to the sketch of Da Vinci. The shape of the aircraft is made of wood, canvas, etc. at the time. On both sides of the aircraft, there is a pair of membrane wings. The structure and shape exactly like bats or pterosaur. These wings can reach 11 meters. The pilot bears this huge aircraft and drives by stepping on a power pulley constantly, and this driving force is magnified by the hand shaft, and at the same time provides power to the improvement device.
Is when designing this aircraft, Da Vinci always has a idea: as long as the strength is sufficient, you can fly. It seems that the genius of the Renaissance may create a history of human flight before the Wright brothers. In fact, the earliest aircraft's mechanical design is perfect, but because the power provided by the person itself is not proportional to the self -weight of the aircraft itself, it cannot be actually applied. In fact, Da Vinci claims that his invention also provides a helicopter, not an airplane that can really work. To this day, people have also regarded Da Vinci's design as the ancestor of the helicopter.

9. He designed the primary robot
. What is even more wonderful is that Da Vinci also designed a method to perform heart repair surgery.
Da Vinci has claimed that he has not been educated by books, and nature is his real teacher. And knowing nature, knowing yourself. The genius of the Renaissance spared no effort to perform. In order to know humanity, Da Vinci personally dissected dozens of corpses, and accurately understood and drawn the human bones, muscles, joints, and internal organs.
After multiple anatomy, Da Vinci discovered the metabolism of blood on the human body. Blood brought nutrients to all parts of the body, and took away the waste from each part. In specific anatomy, Da Vinci found that the heart was composed of 4 cavities and drawn the heart valve diagram.
In fact, Da Vinci did not even have a concept of work mechanism of the human circulation system that year. What's even more amazing is that in 2005, a British surgeon also used Da Vinci's designed method for heart repair surgery. However, the study of anatomy did not bring reputation to Da Vinci at the time, but was slandered by countless defamation.
, this is the in -depth understanding of the human body. Da Vinci even draws the first humanoid robot in the Western civilization world in the manuscript.
Da Vinci gave the robot a shell of wood, leather and metal. And how to move the robot to make Da Vinci hurt his brain. In Da Vinci's idea, he thought of using the lower gear as a driver. Thus the gear of the two mechanical rods and a disc gear in the chest, the robot's arm can wave, sit or stand. What's more, it can be rotated or even opened with the head through a transmission rod. And once the drum device is equipped, this robot can even make a sound.
turns out that more than 500 years ago, the prototype of the robot had already been available.

10. It is the "Da Vinci Motor" that ignites the fire of modern car inventions.
Da Vinci's manuscript (about 5,000 pages existing more than 5,000 pages) is still affecting scientific research today. The true encyclopedia of Century Science and Technology.
The early, Da Vinci was dissatisfied with the four rounds of carriage at the time. In his scientific world, the shadow of a car has long been. In fact, it is the "Da Vinci Automobile" that ignites the fire of modern cars.
Since it is a car, it is necessary to consider the problem of power, Da Vinci installed two springs in the middle of the car to solve this problem. The rear wheels of the manpower rotating cars make each gear bite each other, and the spring tighten will cause force, and then pass on the wheel through leverage.
So how to control the speed? Da Vinci also thought. He installed a disc device on the body, and many square wooden blocks were set on the surface of the disc, which connected to the disk with the other end of the hardcore connected to each wheel. This is the device used to control the speed. The more wooden blocks placed in the disc fan, the greater the friction between the hardcore, the greater the resistance, the slower the operating speed of the wheel, and the longer the distance of driving.
of course, Da Vinci also thought of the brake device. There is a wooden block between the gears. Pulling the rope and stuck the wooden block between the gears, the car can stop. However, this car cannot be carried, because the power of the spring alone cannot be driving for a long distance. At the same time, Da Vinci also cleverly applied the spring on the clock design. Later, the principle used by large watches was from Da Vinci. Just in this idea, the elasticity of the spring is replaced by the gravity of the object, and the gravity of the objects down is evenly passed through many gear bite, and the clock can be kept at a uniform speed.
In addition, the excavation machine, diving machine, crane, camera, heating machine, thermometer, thermometer ... Da Vinci has numerous invention designs. These inventions can make our world scientific civilization process 100 years in advance.

11, obsessed with the mechanical world
underwater respiratory device, pulling device, clockwork transmission device, drill device, reverse spiral, differential spiral, textile expansor ... Vinci presented his countless wonders in front of the world. At the beginning of the story, I have to talk about the experience of Da Vinci who first learned to paint in Florence. In fact, this experience opened the door of artist Da Vinci, and also opened the door of scientist Da Vinci.
In 1460, Da Vinci came to Florence with his father, began his apprenticeship career, and began to learn painting. Da Vinci, who studied painting, participated in the installation of giant copper balls on the Dome Lighting Tower of the Virgin Mary Cathedral of Florence, which contacted and felt the magic of a variety of mechanical systems.
The Virgin Mary Cathedral is the beginning of the Renaissance building. When Da Vinci installed a giant copper ball on the dome lighthouse, he witnessed the efficiency of mechanical devices such as a three -speed improvement machine, and deeply felt the magic. As a result, the design concept of the mechanical system of Brunesky has a great impact on Da Vinci. At that time, a group of "Siena Engineers" also had an important impact on the scientific world of Da Vinci.
Themier -designed by the engineers of Siena like a boat silt mud excavator, which is used to remove the gravel and sludge of shallow water, and there is also a paddle boat that can improve the loading capacity and speed up the driving speed. The invention of these Siena engineers has made Da Vinci a huge interest in the magic of machinery.

silver quartz gemstone jewelry wholesale He is a painter, astronomer, inventor, and architectural engineer with profound thinking, knowledgeable, versatile, and versatile. He is also good at sculpting, music, invention, architecture, and knows mathematics, physiology, physics, astronomy, geology and other disciplines. He is both versatile and diligent and diligent. All his scientific research results were stored in his manuscript. Einstein believed that if Da Vinci's scientific research results were published at the time, science and technology could be 30-50 years in advance.
