Baidu brain power card

1. Wang Xia's words, I think like this, you can directly add from the personal center.

2. Just now I tried. You can make a comparison in the project details of BTC or BCH. You can choose different indicators

3. The computing speed of the world's most decisive, of course, is the electronic computer. However, there are some people who are not as fast as computers, and they are not mathematicians. Their amazing computing power is often innate, not acquired through training< In the afternoon of April 23, 1981, in Paris, France, Klein from Holland performed mental arithmetic in front of 3000 audiences. One audience asked him to calculate 38x22x27, and he immediately wrote the answer 22572. He was asked to do mental arithmetic ÷ 29. When he wrote 156.172413931033414827... All the way to the edge of the blackboard, it took only 20 seconds. When people ask Klein how to calculate, he always says with a smile that it is difficult to express in words, because some algorithms can be understood by others, but some algorithms cannot be understood by others, let alone applied

how is this amazing computing power of human brain obtained? Why can some people match the speed of a computer? How powerful is the human brain? So far no one has been able to answer.

4. Transportation in three stages: the first stage: the donkey carries 1000 carrots for 200 kilometers, unloads 600 carrots, and brings 200 carrots back to eat on the road. Return to the starting point, transport 1000 more, 200 kilometers away, unload 600 and bring 200 back to eat. In the end, 1000 of them were transported to 200 kilometers without returning. At this time, there are 2000 carrots left, and the donkey eats 1000. The second stage: advance 333 km from 200 km to 533 km and transport twice. The method is the same as above. At this time, the donkey ate 999 carrots, leaving 1001 carrots. The third stage: one carrot was fed to the donkey, and the remaining 1000 were carried forward by the donkey. After walking 467 km to the destination, the donkey ate another 466 carrots (one had been fed before), and finally only 534 carrots were left.

5. Loss 245, the original purchase price is 40 yuan (80 yuan a pair), loss purchase 80, counterfeit money to make up for the loss 65, compensate for counterfeit money 100, namely: 80 + 65 + 100 = 245.

6. If there is a direct collision between wisdom and power, of course, those who have power will become the final winner, because no matter how powerful wisdom is, even if it can calculate everything, without any action power, even a child can die without any super power.

Professor Richard Lynn is a senior researcher in the field of intelligence quotient. He began to engage in the research of ethnic intelligence quotient in 1977. In 2005, Professor Lynn published the results of a "bold" study, saying that "men have five IQ points higher than women". Later, Lynn also compared the average IQ of college students in the world, and found that the IQ of American college students is 110, ranking first in the world, while that of British college students is 109

In 2006, Professor Richard Lynn published a new book called "the difference of ethnic Intelligence: an evolutionary analysis", which summarized the ranking and reasons of the differences of ethnic intelligence in different regions, and drew the IQ world map accordingly

on the world map of IQ drawn by Professor Lynn, Jews have the highest IQ, with an average of more than 125, followed by Germany 109, Holland 107, Poland 106, and Europeans and East Asians have the highest average IQ in the world, with an average of 105. Then came Eskimos (91), Southeast Asians (87), Native American Indians (87), Pacific Islanders (85), South and North Africans (84), sub Saharan Africans (67), and Australian Aborigines (62). The regions with the lowest IQ are the jungle people in the desert plateau of South Africa and the pygmies in the rainforest of Congo (Brazzaville), with an average IQ of 54

Objectively speaking, scientific testing of children's intelligence can help parents find the golden key to their children's intelligence as soon as possible, and correctly understand their children's strengths and weaknesses. For children with low intelligence, it can be found and treated earlier. If the method is improper, premature and rash to the child blind qualitative, it may directly affect the healthy growth of children in the future

if the child shows extraordinary intelligence or ability, it is suggested that the IQ test can also be done without the child's knowledge. The test methods for supernormal children are complex, and experts will adopt a variety of evaluation methods to identify their potential and ability, such as nomination method, observation method, dynamic evaluation method, performance and archiving and other non-traditional methods

intelligence quotient (IQ) refers to the index of comparing the scores of indivial intelligence tests with those of subjects of the same age. It is the standard to measure the level of indivial intelligence. The concept of intelligence quotient was put forward by Professor Terman, a psychologist at Stanford University

At the beginning of the 20th century, Alfred Binet (1857-1911), a French psychologist, and his students compiled the world's first intelligence scale. According to the scale, the average IQ of ordinary people was set at 100, while that of normal people was mostly between 85 and 115. Intelligence is controlled by genes, which cannot be changed by human beings. Due to a variety of congenital factors, people's intellectual development will be different. Through a series of standard tests to measure people's intelligence development level in their age group, it must be combined with spirit quotient (SQ). It is the ability of people to know objective things and use knowledge to solve practical problems. There are many aspects of intelligence performance, such as observation, memory, imagination, creativity, analysis and judgment ability, thinking ability, adaptability, reasoning ability, etc., including cultural quotient (CQ). At present, intelligence consists of three abilities: short-term memory, reasoning ability and language ability

later, Professor Terman introced the scale to the United States and revised it as Stanford Binet intelligence scale, and used the ratio of psychological age to physiological age as the index to evaluate children's intelligence level. This ratio is called intelligence quotient, which is expressed by the formula: IQ = ma (psychological age) / Ca (physiological age) × 100 People call this IQ ratio IQ

8. Intelligence distribution of Stanford Binet scale: 140 or above is very excellent (genius); 120-129 were excellent; 130-139 were abnormal; 110-119 are superior and intelligent; 90-109 is medium; 80-89 were middle and lower; 70-79 is critical intelligence deficiency; Below 70 is mental retardation

intelligence refers to the general mental ability of biology. It refers to people's ability to know and understand objective things and use knowledge and experience to solve problems, including memory, observation, imagination, thinking, judgment, etc. This ability includes the following: understanding, judgment, problem solving, abstract thinking, expression of ideas and language and learning ability. When considering animal intelligence, the definition of "intelligence" can also be summarized as: the ability to effectively adapt to the environment by changing oneself, changing the environment or finding a new environment. Intelligence, also known as intelligence, is the ability of people to understand objective things and use knowledge to solve practical problems. Intelligence includes many aspects, such as observation, memory, imagination, analysis and judgment ability, thinking ability, adaptability and so on. The level of intelligence is usually expressed by intelligence quotient, which is used to indicate the level of intelligence development. In particular, it should be pointed out that intelligence does not refer to wisdom, and there is a certain difference between them<

intelligence components

observation ability
refers to the brain's ability to observe things, such as finding new things through observation, having a new understanding of sound, smell, temperature, etc. in the process of observation, and improving the ability to understand the essence of things through the observation of phenomena. We can add some training contents in learning and training, such as observation and imagination items, so as to improve students' observation and imagination through training

attention
refers to the ability of people's psychological activities to point to and focus on something. For example, our good students can concentrate on reading books and researching topics for a long time, while their interest in other unrelated games and activities is greatly reced, which is the embodiment of strong attention<

memory is the ability to memorize, maintain, re recognize and reproce the content and experience reflected by objective things. For example, when we grow old, we still remember the image of our father and mother when they were young, the family environment when we were young and other scenes, that is, people's memory plays a role<

thinking ability
is the indirect and general reflection ability of human brain to objective things. When people learn to observe things, they will graally classify and summarize different objects, events and experiences. Different types can be summarized by thinking. Thinking power is the core of intelligence<

imagination
is the ability of people to create new images in their minds on the basis of existing images. For example, when you talk about cars, I immediately imagine all kinds of car images. That's the reason. Therefore, imagination is generally completed on the basis of mastering certain knowledge.
