1. computing power is a measure of bitcoin network processing power. That is, the speed at which the computer calculates the output of the hash function. Bitcoin networks must perform intensive mathematical and encryption related operations for security purposes. For example, when the network reaches a hash rate of 10th / s, it can perform 10 trillion calculations per second
in the process of getting bitcoin through "mining", we need to find its corresponding solution M. for any 64 bit hash value, there is no fixed algorithm to find its solution M. we can only rely on computer random hash collisions. How many hash collisions can a mining machine do per second is the representative of its "computing power", and the unit is written as hash / s, This is called workload proof mechanism pow
< H2 > extended data
computing power provides a solid foundation for the development of big data, and the explosive growth of big data poses a huge challenge to the existing computing power. With the rapid accumulation of big data in the Internet era and the geometric growth of global data, the existing computing power can no longer meet the demand. According to IDC, 90% of the global information data is generated in recent years. And by 2020, about 40% of the information will be stored by cloud computing service providers, of which 1 / 3 of the data has value
therefore, the development of computing power is imminent, otherwise it will greatly restrict the development and application of artificial intelligence. There is a big gap between China and the advanced level of the world in terms of computing power and algorithm. The core of computing power is the chip. Therefore, it is necessary to increase R & D investment in the field of computing power to narrow or even catch up with the gap with the developed countries in the world

3. Calculation ability must pass, thinking ability is also constantly strengthened, at the same time learn useful mathematical knowledge
certainly not, but don't lose heart, you can prove your ability with your actions, and the teacher will change you in the future
this is about to be refueled. The cost of changing majors is high! Thinking ability is cultivated on the basis of calculation, but when you have a certain basis of calculation, if you want to further learn mathematics, you have to exercise your thinking ability. The difference in thinking ability is reflected in some problems. Some people know how to do it at a glance, while others can only react after watching it several times, and even don't know where to start!
4. Mathematics, physics and chemistry, commonly known as "Mathematics and chemistry", are actually training our logical thinking ability.
my own experience, formulas and theorems must be digested and understood, and I must never memorize them by rote.
my own learning methods, formulas and theorems, I must also do my own derivation to see what is going on, After digesting and understanding, the impression will be deepened and the knowledge points will be connected. If I can't think of the formula and theorem for a moment, I can dece it again
5. Mathematics can well cultivate people's rational thinking, is a very important way of thinking and cultural spirit. Learning mathematics can help us to learn how to solve problems, and we can also learn many useful ideas, such as calculus. In the University, non mathematics majors study higher mathematics in order to promote the idea of calculus.
6. The core quality of mathematics can be understood as the comprehensive ability with specific significance that students should achieve in learning mathematics. The core quality does not refer to specific knowledge and skills, nor is it the general mathematical ability. Core literacy is based on mathematical knowledge and skills, and higher than specific mathematical knowledge and skills. Core literacy reflects the essence and thought of mathematics, which is formed in the process of mathematics learning, and has the characteristics of comprehensiveness, integrity and persistence. Mathematics core literacy is directly related to the goal and content of mathematics curriculum, which is of great significance and value to understand the essence of mathematics, design mathematics teaching, and carry out mathematics evaluation.
7. The definition of Greek mathematics generally refers to from 600 B.C. to 600 A.D., Greek mathematics is active in the Greek peninsula, love... Its mathematical research center is three geometric mapping problems, three geometric problems
8. The core of physics is mechanics. The core of mathematics is function and relation
9. The connotation of ten core concepts in "mathematics curriculum standard for compulsory ecation stage (Revised Draft)" in the standard, ten core concepts are designed, which are increased compared with the original standard experimental draft, such as sense of number, symbol awareness, space concept, geometric intuition, data analysis concept, operation ability, reasoning ability, model thinking, application awareness and innovation awareness. 1. Number sense mainly refers to the perception of number and quantity, the relationship between numbers, the estimation of operation results and so on. The establishment of number sense is helpful for students to understand the meaning of number in real life and understand or express the quantitative relationship in specific situations. 2. Symbol consciousness mainly refers to the ability to understand and use symbols to express the number, quantity relationship and change law. We know that the use of symbols can be used for operation and reasoning. In addition, we can get a conclusion, which is general. Symbol consciousness helps students understand the use of symbols, and is an important form of mathematical expression and mathematical thinking. 3. The concept of space mainly refers to the abstract geometric figure according to the characteristics of the object, the description of the real object according to the geometric figure, the orientation of the real object and their mutual position relationship, the description of the movement and change of the figure, and the drawing of the figure according to the description of the language. 4. Geometric intuition mainly refers to the use of graphics to describe and analyze problems. With the help of geometric intuition, complex mathematical problems can be simplified and visualized, which is helpful to explore ideas to solve problems and predict results. Geometric intuition can help students understand mathematics intuitively, and plays an important role in the whole mathematics learning. 5. The concept of data analysis is to understand that in real life, there are many problems that should be investigated first, collect data, and make judgments through analysis. Experience the information contained in the data, understand that there are many kinds of analysis methods for the same data, we need to choose the appropriate method according to the background of the problem, and experience the randomness through data analysis. On the one hand, for the same thing, the data received each time may be different. On the other hand, as long as there are enough data, we can find the rules. Data analysis is the core of statistics. 6. Operation ability refers to the ability to operate correctly according to rules and operations. It is helpful for students to understand the computational power of operation and seek a reasonable and concise way to solve problems. 7. Reasoning is the basic way of thinking in mathematics, which is often used in people's study and life. Reasoning generally includes reasonable reasoning and dective reasoning. Dective reasoning is a process of logical reasoning, proof and calculation based on known facts and certain rules. In other words, from the perspective of thinking form, it is a process from general to special. In geometric proof, it is actually a form of reasoning. Reasonable reasoning is a way of thinking that starts from the existing facts, comments on some experience and intuition, infers through inction and analogy, and obtains some possible conclusions. Different from dective reasoning, it is often a kind of reasoning from special to general, so the conclusion obtained by reasonable reasoning is not necessarily right. It is usually called conjecture and conjecture, which is a possible conclusion. 8. The process of establishing and solving the model includes abstracting mathematical problems from real life or specific situations, using mathematical symbols to establish the quantitative relationship and change rules of mathematical models such as equations, inequalities and functions, and then finding the results and discussing the significance of the results. The study of these contents is helpful for students to form the idea of model, and improve their interest in learning mathematics and application consciousness. 9. Application consciousness is to emphasize the connection between mathematics and reality, the connection between mathematics and other disciplines, how to use the mathematics learned to solve some problems in reality and other disciplines, of course, it also includes using part of mathematics to solve problems in another mathematics. 10. The cultivation of innovation consciousness is the basic task of modern mathematics ecation, which should be reflected in the process of mathematics teaching and learning. The foundation of innovation is to find and put forward problems by students themselves, and the core of innovation is to think independently and learn to think.
10. Finance is a very complex concept, which refers to various economic activities, such as currency issuance, circulation and withdrawal, even loan issuance and withdrawal, deposit income withdrawal, exchange and so on. It is a very popular concept and field at present. Very popular and sought after. For example, the finance major business school in the university is always the most popular. Working in banks or securities companies, funds and other companies is also considered to have a good future
Finance is a collective expression of a complex and huge instry, and most people think that mathematics is good. There are comparative advantages in financial development. Finance is closely related to mathematics, but it is not equal to the core of finance
On the other hand, as important as mathematics is the understanding of many financial concepts and logic. For example, the economic crisis in western capitalist countries has a cycle. To learn finance, we should also understand the causes of the economic crisis and the solutions to the economic crisis. Even some phenomenon is a sign of economic crisis. Or what kind of situation, indicating the extent of the economic crisis, the understanding of these concepts. As well as the market trend forecast as well as the market present situation accurate analysis is the study finance essential ability
