Human computing power

1. 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.

2. Blockchain is a basic technology of virtual currency. Its significance lies in being open, fair and tamperable, just like a public account book

3. computation ability of human

4. For modern people,
Computer calculators are basically used to solve calculation problems,
obviously become more and more lazy,
and I feel that I can get my calculation ability through more practice,
after I am familiar with calculation methods and engineering,
my calculation ability has been improved

5.

If we use pure mathematical calculation ability to compare, human's achievement is much worse than that of computer, such as the factorial of 1000, which can be completed in less than half a second with ordinary home computer calculation, and the result must be correct; If we calculate the factorial of 1000, I'm afraid we can't finish it in one month. Even if we finish it, the result is basically not correct

human brain can directly process a lot of analog signals, and human brain has the real sense of "intelligence", which is currently impossible for all computers

The figure below shows the factorial result of 1000 calculated by the computer. If you look at this number, you can see why people are wrong... (PS: if this result is expressed by scientific counting method, it is about 4.024 times 10 to the power of 2567)

6. Maybe you should go to see Zhou Wei, the most powerful brain. He was bullied by his classmates every day in the fifth grade, but he is really a genius. Therefore, human brain is invincible, just because there is no such person.

7. The difference between humans and animals is that they are good at using tools

8. The premise of this sentence is "computer ability". This sentence is equivalent to that human beings are inferior to calculators in computing power. This is obvious. People can also calculate, but the accuracy and speed are not guaranteed

Where is the ability of computer compared with human? Fast speed, no fatigue, no rest, no error in calculation, which is beyond people's reach. The computer is programmed by human. The operation of these programs is repetitive and the workload is huge. People can do this, but it is time-consuming and labor-consuming, and the accuracy is difficult to guarantee

for another example, the calculation of missile trajectory has reached tens of thousands of times, but only dozens of formulas and calculation methods need to be used. Using the computer to set dozens of calculation formulas and input different numbers can make accurate calculation.

9. There is no comparability between the two things ~
human beings rely on the creativity generated by desire. The computer is just a simple computing machine, and the most powerful computer is man-made

10.

Although we humans have mastered very advanced technology, in fact, the exploration of the body is still in its infancy, mainly because we humans do not have much advantage in the micro world. And for our brain research, in fact, has never stopped, since ancient times, countless talents are thinking about how the brain works. Why are all human beings, their IQ will have a big gap, why some people can become genius, and some people are destined to be ordinary people{ Can the human brain continue to be developed in the future

in my opinion, as human beings don't recognize the importance of science and technology, their intelligence level is constantly improving, especially for some practical writing, their intelligence has been developed in the early stage, and their intelligence will surpass their parents when they grow up. So in the future, the development level of human brain may really exceed that of the present
