There is a man named Krakutno in Ryazan, Russia. His occupation is just an ordinary shop assistant. The sight of smoke rising from the roof made him daydream, and he repeatedly imagined whether he could use flying smoke to go to heaven. 173 1, he was excited by his own ideas, so he made a fat pocket and sat in the collar under it. When the pocket is full of hot smoke, it will really rise slowly. When he was about ten meters in the air, a gust of wind blew him to the bell tower, and he grabbed the rope of the bell tower to avoid being killed. This is probably the earliest balloon flight experimenter.
1August 783, the first hydrogen balloon was launched in France, and the same year1October 165438+ hot air balloon was launched for the first time, sailing for 9000m.
1783165438+1October 2 1 day, the French Rozier and Dahllund took a test flight in a new hot air balloon made by montague. This balloon is more than 20 meters high and about 15 meters in diameter. It rose to the height of 1000 meters, floated over Paris for 25 minutes, and finally landed safely at a distance of about 9000 meters. This is the first successful flight of mankind.
1783 On August 26th, the first hydrogen balloon rose into the sky. This was done by French physicist Charles. It is 4 meters in diameter and made of silk and rubber. 1 783 65438+February1,Charles took off from Paris in a hydrogen balloon with a diameter of 8.6 meters and flew 45 kilometers in two hours, realizing the first manned flight of the hydrogen balloon.
Who was the first person to play yo-yo in the world? It's hard to say, because yo-yo was originally used as a weapon by a country in history, and later it was made according to diabolo.
Who was the first person to travel around the world? Magellan didn't travel around the world himself. When he went to Indonesia, he clashed with the locals and was killed. To be precise, his fleet was the first to sail around the world.
Who was the first person to travel around the world/Magellan? The reasons are as follows: Magellan 1480 was born in a shabby knight family in northern Portugal. /kloc-entered the palace at the age of 0/0 and served as the queen's attendant. /kloc-entered the Portuguese national maritime office at the age of 0/6, so he is familiar with maritime work. At that time, Columbus had discovered the new continent of America, and Da Gama also returned from India, bringing back great oriental wealth. With longing for oriental wealth and ocean exploration, Magellan joined an overseas expedition in 1505 and began his ocean exploration career. During this expedition to India, Malacca and Malay Archipelago, in order to compete with Arabs for trade land and gain maritime hegemony in South Asia, the expedition fought several wars with Arab businessmen and residents along the way, and Magellan was injured three times. After Magellan recovered from his injury, the ship ran aground on the way back to Portugal. When everyone was disheartened, Magellan stepped forward and led the surviving sailors to overcome many difficulties until they were rescued. Because of this, Magellan was promoted to captain and was left in India. Since then, Magellan has participated in the colonial wars in India and Southeast Asia and conducted them in this region.

Who was the first person to find dinosaur fossils in the world? The lady is waiting for her husband to come back at home. She is always worried that he will catch cold. Later, Mrs Mantell couldn't sit still, so she took her husband's clothes and went out to meet him in the direction of his house call. She walked on a road under construction, and the newly cut steep walls on both sides of the road exposed layers of rocks. She walked habitually, observing the new rock formations on both sides. Suddenly, a shiny thing caught her attention. "What is this?" While talking to herself, she stepped forward to watch carefully. Wow! It turned out to be some strange-looking animal tooth fossils. These fossil teeth are so big that Mrs Mantell has never seen such big teeth. The excitement of discovery made Mrs mantel forget to send clothes to her husband. She carefully took these fossils out of the rocks and took them home.
Later, Mr mantel went home. He was shocked when his wife showed him the newly collected fossils. He has seen many ancient animal tooth fossils, but none of them can be similar to such a big and strange tooth.
To tell the truth, Ye Wei has never seen this kind of fossil, and all the books and papers written by senior scientists he has read have never mentioned this kind of fossil. However, Ju Ye Wei made a judgment based on his rich knowledge of zoology. He thinks that the teeth are rhinoceros's and the bones are hippopotamus's, and he is not too old.
Mr Mantel is very skeptical about the evaluation of living in Ye Wei. He thinks that the conclusion of living in Ye Wei is too hasty. He decided to continue his research. From then on, whenever he had the opportunity, he went to museums all over the country to compare specimens and consult materials.
One day two years later, he met a naturalist who worked in the Royal College Museum in London. He is studying an iguana, a modern lizard living in Central America. Therefore, Mr Mantel took those fossils to the Royal College Museum in London and compared them with the teeth of iguanas collected by naturalists, and found that they were very similar. Overjoyed, Mr mantel concluded that these fossils belong to an extinct ancient reptile similar to an iguana and named it "the teeth of an iguana".
Later, with the discovery of more and more fossil materials, people have a deeper understanding of these ancient animals. We know that the so-called "iguana's teeth" are actually a member of a wide variety of dinosaur families; It does belong to reptiles such as iguanas, but it is farther related to real iguanas than to other dinosaurs! However, according to the biological naming rules, the Latin word of the earliest scientifically recorded dinosaur name has not changed, and it still means "teeth of an iguana". However, its Chinese name was translated into Iguanodon.
So please remember: Iguanodon is the earliest recorded dinosaur in the history of science. At the same time, don't forget the name Mantel and his wife who loves nature.
Who first discovered dinosaurs?
The story of prout-Garon-Garon
Mrs Mantell found the story of dinosaurs really romantic. Mr Mantell was able to explore the ownership of dinosaurs with a rigorous and realistic attitude, which was indeed the first step for human beings to study dinosaurs scientifically and understand them.
But in history, humans have long discovered dinosaur fossils, but at that time, due to limited knowledge, they could not explain them correctly.
As early as 1000 years ago, during the Jin Dynasty in China, dinosaur fossils were discovered in Wucheng County, Sichuan Province. But people at that time did not know that it was the remains of dinosaurs, but regarded them as the bones left by the legendary dragons.
Based on the clues found in a historical novel "Mr. milken's Wife", a researcher named Huster at the University of Reading in England recently announced that he had finally discovered the following fact: 1677, an Englishman named prout-Garonne-Garonne wrote a natural history book about Oxford. In this book, prout Gallon Gallon describes a huge fossil leg bone found in a quarry in the parish of Karovilla. Prout-Garonne-Garonne drew a good illustration of this fossil, and pointed out that this thigh bone is neither cow's, horse's, nor elephant's, but belongs to a giant bigger than them.
Although prout-Garonne Province-Garonne Province didn't realize that this fossil was a dinosaur, or even associated it with reptiles, the specimen he described with words and illustrations has been identified by later paleontologists as the thigh bone of a dinosaur called Megalodon, and this fossil was discovered 145 years before Iguanodon was discovered in Mantels. Therefore, Hastert thinks that prout-Garonne-Garonne should be the first discoverer and recorder of dinosaur fossils.
The origin of the name "dinosaur"
In fact, the history of human discovering dinosaur fossils must have a long history. Long before Mantel and his wife discovered Iguanodon, Europeans knew that there were many grotesque huge bone fossils buried underground. But at that time, people didn't know their exact ownership, so they were always mistaken for "the remains of giants." As for China, as early as 2,000 years ago, we began to collect large ancient animal fossils unearthed underground for medicine, and called these fossils "keels".
Who was the first person in the world to make canned food? Abel, a French couple who manages candied food, devoted all her energy to continuous research and practice, and finally found a good way: put the food into a wide-mouth glass bottle, cork the bottle, heat it in a steamer, then plug the cork tightly and seal it with wax. In this way, the earliest cans appeared.
Who was the first man on Mars in the world? So far, people on earth have not been to Mars.
Who was the first man on the moon in the world? Neil alden armstrong (1930) was born on August 5th in WaPaccone Tower, Ohio. 1955 obtained the Master of Science degree in aeronautical engineering from Purdue University. 1949- 1952 served in the us navy (pilot). From 65438 to 0955, he joined the Lewis Flight Propulsion Laboratory of the National Aviation Technical Advisory Committee (later NASA), and then worked as a test pilot at the Edwards High Speed Flight Station in California. 1962- 1970, astronaut of manned spacecraft center of national space administration. 1March, 966, special pilot of Gemini 8 spacecraft. 1On July 20th, 1969, American astronauts neil armstrong (pictured inside the helmet) and buzz aldrin (pictured) landed on the moon for the first time in the Apollo1/kloc-0 spacecraft.1July, 1969, they took Apollo -66 with Aldrin and Collins (he was the commander). On July 20th, Armstrong controlled the Eagle Lunar Module to land on the surface of the moon. In the afternoon 10, he and Aldrin walked out of the lunar module and set foot on the moon. Armstrong took the lead in setting foot on the desolate and silent land of the moon and became the first man to land on and walk on the moon. At that time, he said a famous saying that was often quoted on countless occasions: "This is a small step for individuals, but it is a big step for mankind." They spent 2 1 hour on the moon, 2 1 took off from the moon and returned to earth on 24th. In the same year, he was awarded the Medal of Freedom by the President.
