international mathematical contest

There was no fixed title for the International Four-Year Comic Contest. It was a comics competition with the theme of environmental protection. There were different topics in different years. For example, the theme of the first competition was "Imagine the Blue Sky", focusing on air pollution; the theme of the second competition was "I Love My Hometown", focusing on beautifying the community; the theme of the third competition was "Beautiful Water World", focusing on river and ocean pollution; the theme of the fourth competition was "Sunshine Forest Breathing", focusing on forest protection; The theme of the fifth competition was "Earth Beauty, Green Covenant", which focused on garbage sorting and garbage disposal. The upcoming theme of the sixth competition was "Rapid plastic warfare", which called on children around the world to ban plastic products, protect the earth's ecological environment, and save marine life. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

The following is a tutorial for the International Comic Comic Competition's green theme: 1. ** Concept and creativity **: Before you start drawing, you must determine the theme and the environmental protection message you want to express, such as climate change, garbage sorting, water conservation, etc., and design a representative scene or plot for each theme to ensure continuity and logic. 2. ** Drawing a sketch **: Draw four small pictures on a piece of paper, each picture representing the theme of a comic. 3. ** Refine Images **: Add details and elements to each small image to express the theme. For example, when creating the 8th International Green Comics, one could first draw the first comic about deserts and sandstorms, then draw the second comic about planting trees, then draw the third comic about planting trees into forests, and finally draw the fourth comic about improving the ecological environment and making the earth more green and healthy after the early efforts of planting trees. 4. ** Drawing example of specific elements (using water conservation as an example)**: - Using curves and arcs, he drew the faucet and water droplets on the white paper. - Using line segments to draw a quadrilateral as part of the basin, let the water drop into the basin. - Use lines to draw irregular splashes, indicating the splashes caused by water droplets splashing in the pool. - Draw the edge of the basin (such as the edge of a marble basin). - He drew the bottom part of the basin to increase the three-dimensional effect, and finally added the word "save" to complete it. In addition, the creation could be done from the perspectives of humans and animals, humans and plants, humans and the environment, etc., focusing on topics such as biotechnology, natural environmental protection, and the rational use of scarce resources. It could also refer to the China theme of the world environment day (such as the eighth theme of "harmonious co-existence between man and nature") and related environmental protection concepts (such as guiding attention to "carbon peak","carbon neutrality", understanding endangered animals, etc.). <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

It can be very relevant. A mathematical comic can make complex concepts more accessible and fun, increasing understanding.

Mathematical fiction is a genre that combines elements of mathematics and fictional storytelling. It often features mathematical concepts, theories, or problems within a fictional narrative.

Mathematical analysis was a branch of mathematics that studied real numbers, complex numbers, and their basic operations and properties. It also explored the applications of these concepts in physics, engineering, economics, and other fields. Mathematical analysis was one of the most basic branches of mathematics and also one of the most challenging fields in mathematics. Through the study of mathematical analysis, one could have a deep understanding of the core concepts and methods of mathematics and improve their logical thinking and problem solving ability.

Here are some mathematical questions about dice: 1. ** Problem with probability calculation ** - When rolling a pair of dice, calculate the probability of getting a specific number. For example, the famous mathematician and philosopher Gottfried Leibniz believed that the probability of rolling 11 and 12 with a pair of dice was the same, but this idea was wrong. A total of 12 would only appear in one situation (both dice were 6), while a total of 11 would appear in two situations (5 and 6 or 6 and 5). - If a pair of dice was thrown, the probability of the final number being an even number and the probability of the total number being even and odd were exactly the same. The total number of a pair of dice rolled was between 2 and 12, and the probability was calculated by analyzing the combination of different results. 2. ** Questions related to expectations ** - For example, in a game of eight dice rolls, a player needed to roll a 6 in the game of eight dice rolls. He had rolled three times but none of them was a 6. If a certain percentage of the money was taken out from the bet to the player and he was asked to give up the fourth chance to throw the dice (only this time), how much money was given to him to be fair? This involved determining a fair compensation amount based on the concept of expected value. For a gamble with a bet of V(x) and an outcome of x, the expected value was the probability of the average: expected value (V)=V(x1)p(x1)+V(x2)p(x2)+…If the player's expectation of the transaction remained the same, it could be considered a fair transaction. 3. ** The relationship between the result of the simulated dice and the probability ** - For example, he could simulate dice rolling to study the relationship between theoretical probability and actual results. For example, someone used excel to randomly generate the form of 1 - 4 to simulate dice throwing (A, B, C, D were replaced by 1, 2, 3, 4), and simulated the answers to the multiple-choice questions of the national college entrance examination science subjects to study the scores that could be obtained by throwing the dice, thus reflecting the relationship between the random choice answer (similar to the random result of the dice) and the correct answer, as well as the corresponding probability.

Mathematics stories usually involve an interesting mathematical problem or topic and unfold the story by telling the life of a mathematician or someone related to mathematics. The story would usually tell the mathematicians 'discoveries, challenges, successes, and failures, and how they applied these discoveries to practical problems or solved other difficult problems. A typical mathematical story might involve the following topics: - Exploring the unknown: mathematicians may challenge their own unknown areas to advance mathematics by solving difficult problems. - Discovering new theories: A mathematician may discover new theories or laws that may have an impact on existing mathematical theories. - Mathematics: mathematicians may apply mathematics to practical problems to solve various problems and advance science. - The beauty of mathematics: mathematicians may explore the beauty and meaning of mathematics and how to apply it to human life and other fields. Mathematics stories are often an interesting way to explore the mysteries and meaning of mathematics by telling the stories of mathematicians.

Artificial intelligence mathematical models were the foundation of artificial intelligence technology. The following are a few key mathematical theories involved in building the mathematical model of artificial intelligence: ** 1. Liner Algebra ** 1. ** abstract and formalized ** - It provided a way to abstract specific things into mathematical objects, such as formalizing the research object into a matrix or a matrix. In artificial intelligence, many data and operations could be expressed in terms of matrices. For example, in image processing, an image could be seen as a matrix of the elements, and operations such as transformation and compression of the image could be achieved through matrix operations. - Vectors can be regarded as stationary points in n-dimensional linear space, and linear transformations (which can be expressed in matrices) describe the changes in a coordinate system. The matrix's characteristic values and characteristic matrices could describe the speed and direction of change, which was very important for understanding the law of change in the data in the model. 2. ** Big Data and Machine Learning ** - Matrix operations in linear algebra were widely used in big data processing and machine learning. For example, in neural networks, input data, weights, and so on were in the form of matrices. The forward and backward transmission of data was achieved through operations such as matrix multiplication, so as to train and predict the model. ** 2. Theory of probability and mathematical statistics ** 1. ** Theory of probability ** - The theory of probability was a way of looking at the possibilities that existed everywhere in the world, and it was indispensable in the study of artificial intelligence. With the rise of the Connectionist School, probability statistics became the mainstream tool for artificial intelligence research. - The frequency school and the Bayes school had different views. For example, the frequency school believed that the prior distribution was fixed and calculated the model parameters by the maximum likelihood estimation. The Bayes school believed that the prior distribution was random and calculated the model parameters by the maximum probability. The normal distribution was the most important random variable distribution. 2. ** Mathematical statistics ** - Mathematical statistics was based on probability theory, but the research methods were different. It studied random phenomena based on observed or experimental data, and made reasonable estimates and judgments on the objective laws of the research object. - Their tasks included inferring the general properties of the sample, using tools such as statistics (the function of the sample, which was a random variable). The unknown parameters of the population distribution (point estimation and interval estimation) are estimated by the sample. The hypothesis test accepts or rejects a judgment about the population by the sample. It is often used to estimate the generalisation error rate of the machine learning model. ** 3. Theory of optimization ** 1. ** Target and Essence ** - The goal of artificial intelligence was optimization, which was to make the best decision in complex environments and multi-body interactions. Almost all artificial intelligence problems ultimately boiled down to solving optimization problems. 2. ** Solution process ** - The theory of optimization was to determine whether the maximum (minimum) value of a given objective function existed and to find the value that made the objective function reach the maximum. For example, in model training, the objective function was treated as a mountain range, and the optimization process was to determine the location of the peak (the minimum value) and find the path to the peak. In the linear search, the first and second derivative of the objective function were needed to determine the search direction; the confidence region algorithm first determined the search step size and then determined the search direction; the artificial neural network and other evolutionary algorithms were important optimization methods. ** 4. Information Theory ** - Information theory studied the transmission, storage, and processing of information. It provided the theoretical basis for data compression and signal processing of artificial intelligence, and also provided support for the learning methods of models. ** 5. Other mathematical theories ** 1. ** Graph Theory ** - Graph theory was a branch of mathematics that studied the study of scattered structures and objects. It was mainly used in search algorithms, decision trees, and other aspects to provide the basis for reasoning and decision-making in intelligent systems. 2. ** Dispersed Mathematics ** - It played a key role in algorithm design, natural language processing, and other aspects. It was one of the foundations of the entire computer science. 3. ** Mathematical logic ** - Research on reasoning and proof was widely used in reasoning engines and intelligent search, providing the basis for reasoning and decision-making in intelligent systems. 4. ** Complex Theory ** - He studied the complexity of computational problems and provided a scientific basis for evaluating the efficiency of artificial intelligence by analyzing the time complexity and space complexity of the algorithm. 5. ** Group Theory ** - A branch of mathematics that studies the structure of algebra and symmetries. It is widely used in image processing, pattern recognition, and encryption to help understand and analyze complex data structures and patterns.

'The Mathematical Crown' was a female novel. The female protagonist, Ro Ye, transmigrated to Earth due to an experimental error. Here, she discovered that the knowledge that was originally very precious in the Ozer Continent was widely spread on Earth. In the story, the female protagonist used to live in the magical world. After she transmigrated to modern society, she turned from a bad student to a top student. This novel was considered to be slightly delusional. There were a lot of mathematical formulas in the text that looked very powerful, but the level of knowledge was relatively low. The main reason was that it looked powerful. In terms of setting, although the Magic World claimed that science was power and mathematics was the foundation of magic, the power system was different from the Arcane Throne. The potion formula was similar to the Arcane Throne, and the specific role of mathematics in it was unknown. In terms of the plot, there were some logical incomprehensible aspects. For example, the timeline was chaotic. The protagonist casually claimed that he had trapped others for thousands of years, but his own Magic Tower had only been built for more than a hundred years. He seemed to be very powerful, but the time span was unclear. At the same time, the way the male and female protagonists got along was also more chuunibyou. For example, they saw each other as mathematical rivals. The whole story style was similar to the more melodramatic style of replacing the tyrant with the genius. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

Diving contained a lot of mathematical knowledge. From the moment the athlete took off, his trajectory followed the law of parabola when there was no external force. This was because the Earth's gravity had a pulling force on the athlete, and the athlete's initial speed, angle, and body axis rotation determined the flight trajectory and posture in the air. Quan Hongchan had extremely precise control of her body in the air during diving. This involved the law of conservation of angular momentum. In the air, the athlete, as a rotating body, had the law of conservation of angular momentum without external force. She could adjust the position of various parts of her body to change the moment of inertia, thus accurately controlling her body posture. In addition, judging from the process of the athlete hitting the water surface at high speed, when the athlete entered the water, the resistance and surface tension of the water acted on the body. This process also involved mathematical calculations. For example, in order to reduce the splash, the athlete had to keep his body straight and tense at the moment of contact to reduce the impact area of the water surface. There were also mathematical principles related to area calculation. While watching the Olympics, you can also read the wonderful novels related to the Olympics!
