The relationship between the choice of travel mode and mathematics

The relationship between the choice of travel mode and mathematics is a highly instrumental science, which is highly abstract compared with other sciences. At first, computer scientists were inseparable from mathematics. Mathematicians thought computers were dispensable to them, but now they are inseparable from each other. Computers have also raised the status of mathematicians in people's minds. Most mathematicians began to realize the importance of computers, and more and more entered the computer field to play a role. However, with the rapid development of artificial intelligence and global positioning system (GPS) and the leap-forward improvement of computer computing performance, the advantages of computers are more and more in-depth into the field of thinking, so computers apply advanced mathematical theories to practice and solve many practical problems very effectively. For example, the famous four-color problem is proved by computer. There are many practical branches of mathematics in the process of solving problems, such as analytic geometry, wavelet analysis, discrete mathematics, bionic calculation, finite element method in numerical calculation and so on. It lets people know that computer programming combines mathematical knowledge and mathematical ideas.

Software programming is based on mathematical model, so mathematics is the main foundation of computer science, and applied mathematics, represented by discrete mathematics, is the main tool to describe the theory, method and technology of the subject. In software programming, not only many theories are described by mathematics, but also many technologies are described by mathematics. From the aspect of programming of various computer applications, any program that can run on an electronic digital computer with stored programs must first have a constructive calculation method, the data representation must be discretized, and the calculation operation must be carried out by logical or algebraic methods, which must be reflected in the algorithms and programs. In addition, so far, the theoretical basis of the correctness of the algorithm, the semantics of the program and its correctness is still mathematical logic or further model theory. True process semantics is semantics in the sense of model theory. Therefore, the rigor of software programming thinking and the high consistency between subject theory and realization technology are the fundamental reasons for the close relationship between computer science and technology and mathematics. From the perspective of discipline characteristics and discipline methodology, the main basic idea of software programming is mathematical thinking, especially discrete mathematics represented by algebra and logic in mathematics, while program technology and electronic technology are only the product or a technical expression of computer science and technology.

(A) the development of mathematics in the computer field

Now all forms of software are inevitably related to mathematics, and they complement each other. For example, the application of logic in disciplines has developed from early mathematical logic to today's program model theory; The application of mathematics in the discipline has developed from the early abstract algebra to today's graphics and engineering problems. The application of geometry has developed from the early two-dimensional plane computer drawing to today's three-dimensional animation software system, and fractal theory and technology have appeared in the combination with complex analysis; In the development of games and graphics software, coordinate transformation and matrix operation in linear algebra are widely cited. Wavelet theory and algebraic coding theory are introduced into data compression and recovery and information security.

(B) the thinking mode of software programming

The mentality of software programming determines a person's programming level. In the process of programming, the mathematical thinking is clear, and the written program is refreshing. Combined with teaching, through investigation and analysis, it is known that more than 85% students write programs according to grammar when programming, which is completely out of the thinking of software programming. This mentality makes the programs they write quite bad and illogical.

The reason for this kind of thinking in software programming is that they usually do not pay enough attention to the cultivation of mathematical thinking. Many computer majors think: What's the use of learning advanced mathematics? What's the use of learning linear algebra? What's the use of learning discrete mathematics? So they seldom go to these classes, so, so, they stay in the dormitory all day, playing games, installing software and watching C language. I only know that probability problems and matrix knowledge have supplemented other courses, but I haven't learned much. But when they saw

(C) the integration of software programming and mathematical thinking

Many professionals think that math and software programming skills are like Tai Chi and boxing. Strong software programming ability is like punching fast and heavy, which can directly give people a heavy blow. If you are good at math, you are like master Chi of Artest. On the surface, you don't have much strength, but your inner energy is stronger. But the younger a good boxer is, the better. Tai Chi masters are all experienced. Therefore, mathematics is the necessary ability to achieve a master. Although many students seem to feel useless, they will realize its power after reaching a certain level.

The relationship between the choice of travel mode and mathematics

Where is the travel mode choice of Gaode Navigation? Gaode navigation is driving navigation and does not support the choice of travel mode.

What you can choose to travel is the map of Gaode. After determining the target point, select "Here" (don't choose navigation directly), and symbols of various modes of travel will appear at the top of the screen, including driving, bus, walking and so on. You can choose.

1200 km What mode of travel do you currently choose?

Personally, I feel economical and convenient.

It's best to take the bullet train or high-speed rail, and it's also a good choice if you have a discount ticket.

I hope it helps you.

Choose the right way to travel at night. In the evening, when the weather is fine and warm, you can choose to go out and ride a bike to visit the lake with your friends.

How far is it from Lianyungang to Nanjing? Choice of transportation mode and time cost? I travel between Nanjing and Lianyungang all the year round. The actual distance from Xinpu to Nanjing is 370 kilometers. There are many long-distance buses to Nanjing every day, almost every hour or two. Inside the station 100, 60-70 yuan outside. . It takes about three and a half hours to take the expressway, and the slowest to take the national highway is more than four hours. This is the average time. . It takes about 76 or 7 hours to get there by train, which is relatively slow. . . . Half-price tickets for winter and summer vacations have student ID cards. . . . . . .

What is the best way for the elderly to travel? Hello!

Cruise travel is more suitable for the elderly. Because cruise travel is a slow way to travel, you can eat, live and travel on the cruise, which can save the hard work of traveling by boat. When you are resting or sleeping, you have arrived at the next destination from one port.

I hope it helps you. Thank you for your question! For more travel information, please visit Tongcheng Cruise Travel Channel.

How to choose the way to travel to Tibet? Lhasa is the largest highway hub in Tibet, with highways extending in all directions, reaching Linzhi and Qamdo in the east, Xigaze, Gyangze and Zhangmu in the west and Golmud in the north. The Qinghai-Tibet Highway is the main artery of the highway entering Tibet, the asphalt highway with the highest altitude and the longest route in the world, and the shortest journey, the best road condition and the safest highway entering Tibet at present. Qinghai-Tibet Highway is a line operated by passenger buses, and ordinary family cars can also be used on the road. There are grasslands, salt lakes, Gobi, mountains and deserts along the way. The Kunlun Mountain Pass, Wudao Liangshan Pass and Tanggula Mountain Pass are high in altitude and the climate is cold and rainy. Take enough cold-proof clothes and medicines to prevent altitude sickness, such as Omo with oxygen. The northern line of Sichuan-Tibet Highway is the first highway opened to traffic between Tibet and the mainland. Most of the areas it passes through are pastoral areas, with high altitude, sparse population and original and magnificent scenery. The place where the southern line passes is densely populated, with mountains and canyons along the line and beautiful scenery. To enter Tibet along the Sichuan-Tibet highway, you have to climb mountains and mountains and cross rapids and rapids. The journey is difficult and dangerous. The best season every year is May and mid-August to 10. The Sichuan-Tibet line is often closed due to mudslides and landslides, especially in Dabasu and Tongmai sections of Zhou. Yunnan-Tibet Highway is the lowest passage among the four highways entering Tibet, and the highest elevation in the whole journey is only 4300 meters at the Hongla Snow Mountain Pass. August -65438+ 10 is the best driving season every year, and landslides and even mudslides often occur in the rainy season from mid-August to Mangkang, so it is necessary to inquire about the road conditions in advance. There is no direct bus on the Yunnan-Tibet Highway, and you need to change trains many times along the way. There is no bus from Deqin to Mangkang, so you can only take the train.

Remember to adopt

The relationship between home and mathematics is somewhat general. Is it the relationship between numbers or mathematics? Overall optimization belongs to mathematics. There was an article about the time schedule of boiling water in China in middle school, all of which were related to mathematics! Simply put, everything related to numbers belongs to mathematics. In more detail, some problem-solving methods are also related to mathematics! For example, a word "golden section" is often mentioned in real life. Why do girls wear high heels? The reason is that the ratio of a person's upper body to lower body is often less than 0.6 18. If you add the height of high heels, you can achieve just right. Her figure looks particularly harmonious and her visual impact is particularly strong. If one day you and your friends go to Pizza Hut and order a 12-inch pizza, the waiter says it's gone. He says he will give you a 9-inch pizza and a 6-inch pizza in exchange. Your friend thought it was okay and agreed immediately. What about you? After estimation, it is actually a big loss (a 9-inch pizza plus a 6-inch pizza, the total area of * * * is only = 63.62+28.274 = 9 1.894 square inch! Only about 92 square inches! And a 12 inch pizza, the area is 1 13 square inch! )。 Conclusion: Mathematics is really important! In fact, many things around us can be solved by mathematics, but many people don't look at them from a mathematical perspective.
