1. 1、 What is GEC environmental coin

2017 was the year when digital currency ICO was the most popular, and it was also the year when return to zero currency was born

in this year, GEC environmental protection coin was born

according to the official publicity materials, GEC environmental coins are designed and issued by the world environmental entrepreneurship foundation, with a total amount of about 8 billion, which is halved every five years

after crawling the source code of the official website of the world environmental entrepreneurship foundation, I found that the basic thing is to the template< br />
The operation page of GEC project is also low< br />
However, this does not affect GEC pyramid schemes at all

the first is to promise "only rise but not fall"<

GEC's external publicity is "0 investment, 0 risk, 0 operating cost, everyone can participate, everyone is the main body, mining machine is exclusive, dig money and own it, with huge profits"

coupled with the fierce currency price increase of GEC in the past three years, the current price of GEC is more than 1300 yuan, with a three-year increase of more than 18000 times, isn't it a bit exciting? It can be said that it is deeply related to human nature< br />
The second is the essential mechanism of MLM< br />
It is obvious that there are two core ways to get more GEC coins:

2

as a result, the wheel of MLM has turned. According to the official information disclosure, the number of registered users of GEC platform has already exceeded 2 million<

two or three years ago, why GEC is still alive

before that, there were not a lot of funds under the banner of blockchain and mining, such as five element coin, magic root coin, etc., but they would collapse or be cracked by the police in a year<

GEC's issuing organization, the world environmental protection entrepreneurship foundation, was named and exposed by the official media Beijing business daily in April 2019, and pointed out a series of problems, such as high income, head pulling, suspected pyramid selling, illegal ICO and so on. On June 12, it was also listed in the strike list of non legal social organizations by Zhejiang civil affairs department< br />
On April 14 this year, a netizen asked the relevant regulatory authorities whether GEC environmental protection coin is illegal pyramid selling in the voice of red net people. After investigation, longhui County market supervision and administration bureau gave a clear conclusion that the operation mode of "GEC environmental protection coin" is suspected of pyramid selling< br />
See here, a big doubt surged into my heart, why is the qualitative pyramid scheme GEC after three years still alive well?

2. 1、 Find problems and change students' understanding
in order to make students realize the importance of calculation, I first carried out an activity among students: let students collect the mistakes they often make in calculation, which can be carried out by each student himself or through group cooperation, and record the staggered questions after two weeks, including the reasons for the mistakes, It depends on who is looking for it seriously and who is looking for the wrong reason. When the students' enthusiasm is aroused, they shake off the problems:
(1) wrong reading, wrong ing and scribbling. 6 and 0, 1 and 7 are ambiguous
(2) when the column is vertical, the digits are not aligned
(3) do not draft when calculating
(4) one digit addition and subtraction calculation errors lead to errors in the whole question< There are two reasons for "carelessness" from the calculation errors of some students: one is that children's physical and psychological development is not mature enough, the other is that they have not formed good study habits. On the one hand, it is a natural growth process; on the other hand, it can be cultivated by corresponding methods. Therefore, while guiding students to analyze the reasons, it is necessary to highlight the cultivation of students' good learning habits, which is the key to improving their computing ability and the basic requirement of quality ecation< Second, cultivate students' good habit of calculation. Most of the mistakes in calculation are caused by careless, careless and scribbled writing. Therefore, a good calculation habit is the guarantee to improve the calculation ability. In the calculation training, students are required to do one look, two think, three calculate, four check
1. Look: it's serious. How can the result be correct if all the questions are copied wrong? Therefore, students are required to check with the original question or the previous formula in time when ing questions and calculating each step, so as to avoid ing wrong numbers or symbols. There are three points to be done: 1) check with the original question after ing the question; ② Check the numbers on the vertical type with those on the horizontal type; ③ Check the number in horizontal form with that in vertical form
2. When guiding students to do a calculation problem, they should not pick up a pen to do the calculation. They must first examine the problem, make clear what the problem should be calculated first and then, and whether there is a simple calculation method, then they can do the calculation. In addition, the calculation must be accurate first, and then fast
3. Calculation: to write and calculate carefully. The writing of assignments and exercises should be neat, not scribbled, and the format must be standardized. The writing of numbers, decimal points and operational symbols in the title should be especially standardized. There should be appropriate intervals between the numbers, and the vertical type on the draft should be aligned and organized. The calculation should be concentrated and not rush
4. After the calculation, we should first check whether the calculation method is reasonable; Secondly, check whether the numbers and symbols are copied wrong, and whether the decimal point is written wrongly or omitted; Thirdly, we should check and calculate every number and final result in the process of calculation. Therefore, it is an important way to cultivate good learning habits to prevent calculation errors and improve calculation ability< Third, to cultivate students' oral calculation ability and lay a solid foundation.
oral calculation is a calculation method that directly calculates the number by thinking and memory, which is an important part of calculation ability. Therefore, to improve students' calculation ability, we must lay a good foundation for oral calculation
1. In order to improve the accuracy and speed of students' oral arithmetic, I consciously ask students to memorize some special mathematical combinations according to their knowledge structure, such as sum is two numbers of whole ten and whole hundred (73 and 27, 98 and 2, etc.); The proct is two numbers (25) of the whole ten and the whole hundred × 4，125 × 8, etc.); The memory of these results is not only helpful to improve the accuracy of students' calculation, but also greatly improves the speed of students' calculation
2. Arrange exercises in each class. According to the teaching content and students' actual situation, each mathematics class chooses the appropriate time, arranges 3-5 minutes of oral arithmetic practice, and each student prepares a Book (daily practice of oral arithmetic). In this way, it is carried out for a long time, perseveres, and receives good results
3. For example: visual arithmetic training, listening arithmetic training, oral arithmetic, oral arithmetic games, "confrontation", "relay race" and so on, to improve students' adaptability< Fourth, strengthen the teaching of estimation. Estimation can cultivate students' sense of number, guide students to understand "operation" deeply, and help students check the correctness of calculation results. Estimation method can be used to locate the calculation results in advance and quickly determine the value range of calculation results, It can avoid mistakes caused by carelessness. Let the students look at the last digit of the result. If the indivial digits are 3 and 8, the sum of the indivial digits of the result must be 1, and the multiplication must be 4, such as 13 × In a word, the cultivation of students' computing ability should be carried out in the whole process of primary school mathematics teaching. We should not only strengthen the training of students' basic skills, but also pay attention to the targeted training of students. As long as we carefully study, constantly summarize and improve the work, and seriously dig out the ability factors in the calculation problems, the students' calculation ability will be improved.

disk observation

by the end of closing, the Shanghai index was up 0.85% at 2933.99; The Shenzhen Composite Index rose 1.80% to 9889.75; The index rose 2.77% to 1729.08. From the disk, the game, intellectual property protection, cement plate is in the forefront of the list, while the vitamin plate is relatively weak

Future prospect

if you choose instry investment, there will be investment opportunities in four types of instries: the first is the instry with broad prospects and increasing demand in the future, such as biomedicine; The second type is the instry itself is relatively stable, can maintain steady growth of the instry, such as must choose consumption; The third is the turning point of the instry, the fundamentals continue to improve; The fourth category is the low valuation of the instry. Although there will be downward pressure in the future, the instry is growing steadily and the stability of the leading target is high. Today's game instry's soaring, the reason may be the emergence of a third situation

in the game instry, the concept of cloud game is hot. As an investor, the main concern is whether cloud games can bring increment? Has the core business model changed? At present, the game instry is in the transition period from mobile games to next-generation hardware. Under the catalysis of cloud technology and 5g popularization, the increment of cloud games comes from the upgrade of business model and the increase of willingness to pay. We can expect 5g + cloud games to stimulate the instry growth brought by game innovation. From the perspective of instry competition, cloud games have higher computing power and network cost, and the differences in capital strength, resource integration and computing power distribution ability will lead to differentiation of different cloud game platforms, and the big platform has a high probability of winning

operation strategy

instries with undervalued value, such as banking, insurance, home appliances, building materials, etc., as well as high prosperity segments, such as consumer electronics, games, 5g communication, medicine and biology, are worthy of attention Wen Fu, investment consultant, practicing certificate No.: s02606111050006]

5. The man above didn't calculate the cost of bottle and ore machine synthesis. He only needed 6 bottles for 3 liters and 4. He didn't need 8 bottles; Let me calculate for you, each upgrade costs 80W bottles, and ore and synthesis costs:
upgrade to level 2: 8 * 330 + 80 + 10 + 10 = 2740w
upgrade to level 3: 2740 * 8 + 80 + 20 + 25 = 22045
upgrade to level 4: 22045 * 6 + 80 + 35 + 80 = 132465w
1.32 billion yuan (save later) is about 2283 yuan. However, if the property is uncertain, you may have to wash it. If you're lucky, you don't spend money. If you're not lucky, you have to wash it many times.

In his 1687 paper the law of nature, Newton described the law of gravitation and the three laws of motion. These descriptions established the scientific view of the physical world for the next three centuries and became the basis of modern engineering. By demonstrating the consistency between Kepler's law of planetary motion and his theory of gravity, he showed that the motion of ground objects and celestial bodies follow the same natural law; It provides a strong theoretical support for the theory of sun center and promotes the scientific revolution

In mechanics, Newton expounded the principle of conservation of momentum and angular momentum and put forward Newton's law of motion. Optically, he invented the reflecting telescope and developed the color theory based on the observation that a prism diffuses white light into the visible spectrum. He also systematically expressed the law of cooling and studied the speed of sound. In mathematics, Newton shared the honor of developing calculus with Gottfried William Leibniz

extended data:

Newton's main achievements:

1, mechanical achievements

in 1679, Newton returned to the study of Mechanics: gravity and its effect on planetary orbits, Kepler's laws of planetary motion, and discussions with Hooke and framstead on mechanics. He summed up his achievements in the book motion of objects in orbit (1684), which contains the preliminary laws of motion later formed in the principles

Most modern historians believe that Newton and Leibniz independently developed calculus and created their own unique symbols for it. According to the people around Newton, Newton came up with his method several years earlier than Leibniz, but he hardly published anything before 1693, and did not give a complete description until 1704

Newton was devoted to the study of the phenomenon of color and the nature of light. In 1666, he studied sunlight with a prism and concluded that white light is a mixture of light of different colors (that is, different wavelengths), and light of different wavelengths has different refractive index. In visible light, red light has the longest wavelength and the smallest refractive index; The violet light has the shortest wavelength and the largest refractive index. This important discovery of Newton became the basis of spectral analysis and revealed the secret of light color
