In the morning, we took a bus from Florence, and after more than an hour's journey, we soon arrived at the parking lot outside Pisa. It takes more than ten minutes to walk from the parking lot to the leaning tower of Pisa in the city. The city is quiet everywhere, and the tall Mediterranean pine trees conspicuous by the roadside stand straight and smoothly on one side of the road. Branches with long leaves regularly grow obliquely outward, forming a neat crown at the top, which looks like a rooster's crown hanging in the air and an open folding fan used by people in rural summer nights. The trees are neatly arranged and elegant.
Walking into the ancient city of Pisa, I saw the leaning tower in my dream at a glance. When preparing to visit the Leaning Tower of Pisa, the green chemical workers beside the tower are watering the lawn. A series of splashes spread on the lawn like flying fog, reflecting a series of arc-shaped rainbows, castles, churches and green grass through sunlight, forming a beautiful landscape full of vitality.
Tourists of different colors and languages from all over the world have already stood on the edge of the vast lawn and looked around. Facing the leaning tower, they creatively put on various postures to hold the leaning tower with their hands, hoping to make the leaning tower no longer tilt by taking pictures, with natural and positive intentions. This action is a great innovation in the journey. After a while, many subjects spread out all kinds of fun postures, lunging, kicking and stretching their arms forward, as if supporting the leaning tower, which made people think a lot.
I still remember that in middle school, when the physics teacher talked about the law of free fall in class, Galileo, a famous Italian mathematician, astronomer, physicist and philosopher, gave us an example of free fall experiment on the leaning tower of Pisa, and told us Galileo's famous story of pushing the leaning tower of Pisa.
One morning in about 1590, 25-year-old Italian scientist Galileo climbed the leaning tower of Pisa, which was more than 50 meters high. He holds an iron ball weighing 10 pounds in his right hand and a one-pound iron ball in his left hand. He vowed to do the experiment of free falling objects on the leaning tower, and verified that Aristotle's theory of free falling objects was wrong.
It turns out that Aristotle, an authoritative thinker in ancient Greece, once asserted that the speed at which an object falls from the sky is directly proportional to its weight, with heavy falling fast and light falling slow. For example, a 10-pound object falls ten times faster than a one-pound object. Is Aristotle's theory right? In the past 1800 years, people have always regarded this wrong assertion as truth. /kloc-in the 6th century, young Galileo discovered the logical contradiction of this theory. Galileo said after careful experiments that if a big stone falls at a certain speed, then, according to Aristotle's judgment, a smaller stone will fall at a correspondingly slower speed. If we tie these two stones together, at what speed will this new stone, whose weight is equal to the sum of the two stones, fall? After many experiments, he came to two diametrically opposite conclusions. On the one hand, the falling speed of the new stone is slower than that of the first big stone, because adding a stone with slower falling speed will slow down the falling speed of the first big stone; On the other hand, the new stone should fall faster than the first big stone because the weight of the two stones tied together is greater than that of the first big stone. These two contradictory conclusions cannot be established at the same time, so it is illogical to draw Aristotle's conclusion. Galileo, a young scientist, demonstrated and criticized this theory through experiments and pointed out that it was wrong. However, at that time, many conservative theologians, philosophers and physicists in Italy began to accuse Galileo, saying that he was too "arrogant" and that "this is the truth handed down by old scientists, how can he betray it" and so on.
Galileo did not give in. He believed that only science was the only truth. In order to prove his experiment is correct, he decided to climb the leaning tower of Pisa and prove his point through experiments. On this day, Galileo finally climbed to the top of the leaning tower, and thousands of people rushed to watch the excitement of the day under the leaning tower. They looked up to observe what kind of experiments Galileo had carried out. In full view, Galileo took a deep breath on the leaning tower, and then pushed two iron balls with different weights down at the same time with both hands. As a result, people under the leaning tower found that two iron balls with different weights fell at the same speed and both landed at the same time, and people suddenly cheered. When Galileo walked down the leaning tower with a smile, he was immediately lifted up by enthusiastic young students. They cheered the birth of the new theory and celebrated the teacher's courage to challenge great men and win the truth.
It doesn't matter whether this story exists or not. As long as the principle is correct, we should cheer for Galileo, a scientist who is good at innovation and dares to innovate. At the same time, it also tells us that the power of science is infinite. As long as we are good at developing the human brain, we can achieve new success!
I heard the story of Galileo when I was studying in the late 1960s. At that time, I dreamed of going to Italy one day and seeing what the leaning tower of Pisa looked like. This matter has also become my dream for a long time.
I'll believe that when I see it. Seeing the leaning tower in front of us, people in the square are pointing and commenting. I immediately stared at the leaning tower. The leaning tower of Pisa is actually the bell tower of Pisa Cathedral. It was built on the church square in the ancient city of Pisa, located in a group of religious buildings, and is a typical Christian building. The total height of the Leaning Tower of Pisa is 58.36 meters, 55 meters from the ground to the top of the tower, which is slightly lower than the tower in Kaifeng, China. The wall of the above-ground bell tower is more than 5 meters wide, and the top of the tower is more than 2 meters wide, with a total weight of about 14453 tons and a circular foundation area of 285 square meters. The main color of the Leaning Tower of Pisa is mainly beige, and the architectural style is a little Greek. In the leaning tower of Pisa, there is a small arch bridge bent downward between adjacent columns. Above each pillar, there are four small architectural decorations, which are very distinctive. They are surrounded by columns and look like a huge birdcage hanging from the air to the ground. Standing there, it seems that the soul has been sublimated. The leaning tower of Pisa is a world-famous leaning tower and one of the national standards of Italy.
This tower is famous for its inclination. According to the introduction of the local tour guide, I know its past life. As early as 1 173, the then king of Pisa decided to build a white bell tower in Pisa to show off his country and prestige. Pisano design. But unfortunately, one day after the construction started five or six years ago, people found that the tower under construction had slightly tilted, so they had to stop working to ensure safety. It was not until one day after 1994 that Pisa remembered the construction of the leaning tower of Pisa and how to complete it, and specially invited the surveyor Di who repaired the tower. Simone. After careful measurement, it was found that although the tower was inclined, it was not worried about collapse, so craftsmen were invited to continue the construction, and they also tried to straighten the bell tower by heightening the columns on each floor. It was not until 1350 that the bell tower was completely completed. According to statistics, it took 176 years to build the tower, which is the longest in the history of tower building in the world.
The leaning tower of Pisa is inclined because of the particularity of the soil layer under its foundation, and scientists verified it on the leaning tower of Pisa. Scientists and geologists have found that there are several layers of soil with different materials below, alternately forming various soft silt and extremely soft clay deposits, while at a depth of about one meter, it is a groundwater layer. This conclusion is obtained after observing the composition of foundation soil. The latest excavation shows that the bell tower was built on the edge of the ancient coast. Because it has been desertified, the soil sank during construction.
When the whole leaning tower was completed, the center point of the tower top had deviated from the vertical center line by 2. 1 m, and now it has deviated from the center line by 5.3 m. Italian authorities have been trying to save the leaning tower, but all methods have failed. But Pisa people who care about the fate of the Leaning Tower of Pisa don't think so and think it is unnecessary. They firmly believe that "the leaning tower of Pisa is as strong and strong as Pisa people and will never fall down". The most convincing thing is that 1972 and 10 had a strong earthquake in Pisa this month. The earthquake tower shook, and many strong buildings nearby were smashed into mud and turned into dust. However, the leaning tower of Pisa still stands upright, flying like a white crane in the air. The leaning tower of Pisa has been tilted for more than 600 years, which really created a miracle in Europe. In recent years, in order to protect this ancient leaning tower, the Italian government has invested a lot of money and asked experts and engineers to do everything possible to straighten the leaning tower and control its inclination.
Watching, praising and promoting the beautiful leaning tower culture is not only the responsibility of tourists, but also the responsibility of our writers. Seeing the Leaning Tower of Pisa in Italy, I suddenly wanted to kiss the strange Leaning Tower I saw during my domestic tour. They either stand on the mountain, or stick to the rivers and lakes, or stand in the temple, becoming the unparalleled pride of the ancient pagoda in China! Some are as famous as the Leaning Tower of Pisa in Italy, and some even surpass it. If we talk about history and tendency, the leaning tower located in Qianwei Town, Suizhong County, Huludao City, Liaoning Province is known as "the first leaning tower in the world".
The avant-garde leaning tower in Liaoning, China was built more than 300 years before the leaning tower in Pisa, Italy. After several storms, earthquakes and dynasties, it still stands in the tilt. This is an interesting solid brick tower with dense eaves. The avant-garde leaning tower is about 10 meter high, the tower body inclines to the northeast 12 degrees, and the displacement of the tower tip 1.7 meter. It has a stone tower foundation and a brick tower body, which is three stages of octagon. The avant-garde leaning tower has a unique shape and complex technology. The tower seat is sumeru-style, with brick-carved flowers in the middle, and the flat seat carved with lotus "Wan Zi" and cirrus clouds is supported by three arches. There are brick-carved Buddha statues, patterns, lion heads and other patterns on the tower body, with exquisite knife skills and extremely clear lines. The top of each pillar of the avant-garde tower is connected with a Popeye square, and then the eaves of the tower are supported by a bucket arch.
The avant-garde leaning tower has a unique scenery. When people stand under the tower and squint, they will feel that the leaning tower seems to fall head on, giving people a thrilling feeling. For many years, the tower has been tilted but not toppled, so it is called "strange tower". Nowadays, when people get on board and look on, they will feel that the leaning tower seems to have fallen head-on, which is really thrilling. The inclination of the leaning tower of Pisa in Italy is 5.3 degrees, while that of the avant-garde leaning tower is 12 degrees. Inclined but not down, inclined but not down, the inclination has become the boss of the world's leaning tower, which is worthy of the name "the first leaning tower in the world".
The other is the Baoguang Leaning Tower on the tianmashan in Songjiang District. Tianmashan seems to be not high, but the mountain is steep, the ridge of the mountain is close to the east-west, and the shape of the mountain is as unconstrained as the sky, with its head down. In tianmashan Zhongfeng Scenic Area, there is a Millennium ancient pagoda named "Pearl-Protecting and Baoguang Pagoda". According to reports, this ancient pagoda, built in the second year of Yuanfeng in the Northern Song Dynasty, has seven floors and eight sides and is more than 20 meters high. Although the tower of this ancient pagoda is small, it still can't stand the test under the influence of wind, rain, lightning and foundation changes.
Standing under the leaning tower of the pagoda, you can clearly see that the northwest corner of the tower seat is damaged, revealing a big gap with a diameter of 2 meters, which is shocking. The scenery here is very beautiful. Whenever the sun shines through the mist with water vapor at sunrise or evening, a colorful halo will appear around the tower. Some people call this aura magical Buddha's Light, just like the formation principle of Huangshan Buddha's Light and Emei Mountain Buddha's Light, which painted tianmashan with mysterious colors and attracted thousands of good men and women to burn incense and worship. Today's Beaded Lighthouse tilts 7 degrees 10, surpassing the Leaning Tower of Pisa, Italy, and is known as the glory of "the world's first leaning tower". At present, it has been selected as the candidate world record for the first leaning tower in world record association, China.
This pearl tower was originally made of brick and wood. The ancient pagoda caught fire, and the wooden structure was gone, leaving only bricks. However, I don't want another wave of unrest. Because of the wind, rain and lightning, the gaps between the tower bricks are exposed, and there are some yuan dynasty coins between the bricks. Some local people accidentally discovered this secret and came to the Pearl Tower with only bricks to collect ancient money, resulting in a big hole with a diameter of about 2 meters at the base of the northwest corner of the tower, and the tower gradually tilted. The tower base was hollowed out in a fire, but the leaning tower, although inclined, can stand upright in the mountains, even in a tornado, which is amazing. In addition, there is the leaning tower of Huqiu Mountain in Suzhou City, Jiangsu Province; Right Island in the center of Zuojiang River, Chongzuo County, Guangxi, has five floors and six corners, and the tower is 25 meters high. The leaning tower of Guilong is about 1 meter. Yuquan Leaning Tower on Yuquan Mountain in Dangyang, Hubei, etc. Are all famous leaning towers.
Yes, the Leaning Tower of Pisa in Italy is famous for its "leaning but not falling", and the Leaning Tower of China is also famous for its long history and unique story. The inclinations of the avant-garde leaning tower in China and the Pearl-protecting Baoguang Tower listed above all exceed those of the leaning tower in Pisa, Italy, and they are the three largest leaning towers in the world.
A philosopher once said: The Leaning Tower of Italy is famous because of Galileo's physical experiments, Galileo's advertising and publicity for the Leaning Tower, and he introduced the Leaning Tower to the world. This is a historic opportunity. With the development of tourism, Italy once again handed over advertisements to tourists to take pictures and pass them on the square. This kind of advertisement is as powerful as an atomic bomb!
Standing under the leaning tower of Pisa, I once again imitated others to make a posture to support the leaning tower and began to take pictures. I think, if one day, the leaning tower is really righted by a philosopher with science and technology, even if it is righted once or twice, it is also a flicker of wisdom. At the same time, I also believe that those leaning towers located in China, which exude ancient charm, will be as famous as the Leaning Tower of Pisa in Italy through people's various propaganda and sincere recruitment of tourists from all over the world, and will spread the ancient leaning tower culture in China to the whole world!
