Chapter 6: Who is this person?

Xie Yefan was scorned in his heart and decided to go back to the office to write an article to attack this bad phenomenon.
If you can bring up a topic, get a lot of enthusiasm, and you can also increase your popularity!
Qun even thought about the title-"The" Head "in the Subway-Bounce from the Culture of a People"
I thought of this, and he pointed his mobile phone at Zhang Yuan quietly, and planned to use this counter-example as a picture for the article.
He glanced at Zhang Yuan's phone screen again, and frowned.
"Oh, I'm not in love with a two-dimensional girl. It turned out to be a super brain."
"I can't use it for pictures ..."
当然 Of course, he has watched a TV show that is popular all over the country. The "Super Brain" app was specially developed for the sea-selected players.
的 Players who have confidence in their intelligence can do problems on their mobile phones. The top 1,000 people for each season's results can obtain qualifications for the election. After the election, you can show your level to the real scene.
Because it is online network selection, many people will use computers to cheat, resulting in unrealistic results. However, at the time of the election, these cheaters will always reveal themselves.
"Quick calculation, I will do this too!"
Ye Yefan peered curiously, eager to try. He also learned mental arithmetic when he was a child, and now he wants to compare it with Zhang Yuan subconsciously.
"88.8 8 + 88.88 8-8.99 / 8.88 = ... (reserve 4 significant digits)"
Zhang Yuan thought for a few seconds and wrote the answer directly.
"1420"
"Is it so fast?" Ye Fan was surprised, "Although as long as 4 significant digits are retained, the decimals are omitted ... This is a bit interesting."
But he didn't care too much, thinking that Zhang Yuan had been thinking about it for a long time.
The next question, Zhang Yuan pointed his finger.
"Ln (40) (3 significant digits are reserved)"
This time the two stood on the same starting line.
Ye Yefan was full of energy, thinking hard.
"Wait a second, how should the logarithmic function be calculated? What is the formula for the bottom?"
For a short while, my head was a little messy.
I tried hard: "ln (40) = ln (4) + ln (10), then ... hey, no, still can't figure it out, do you want to recite any logarithmic table?"
Zhang Yuan wrote the answer on the screen again.
"3.69"
"The answer is correct!"
Ye Yefan's eyes widened, as if he's gone.
He hasn't figured out how to calculate the logarithm yet. There is no way.
At this time, the other party starts the next question again.
"Sin (24 °) (3 significant digits are reserved)"
What is this? How does a trigonometric function count? Double angle formula? Not right.
Sin (24 °), it is impossible to calculate it by hand!
I saw that the person wrote the answer on the screen again: "0.407"
"The answer is correct!"
"..."
Suffering invisible blows continuously, Ye Fan had a bag in his head and could only give up treatment.
He was also embarrassed to ask, but searched by mobile phone and found the answer he wanted.
原来 "That's the case, hand calculation of logarithmic or trigonometric functions requires Taylor series expansion ... 唉, but these long-trained people are also normal!"
He could not help but chuckle his lips, thinking unconvincedly: What's so great about a quick calculation? This skill is completely useless. Can people count faster than computers?
Maybe, you can write another article to attack the educational institutions that teach mental arithmetic. There is no need to increase the burden on children and learn something that is not important.
I just thought about it, but quietly took out my mobile phone, opened the computer software, and thought: I can't keep up with your mental calculations at the speed of the computer?
Zhang Yuan faintly felt that he was back again, as if someone was looking at himself, looked around, and found nothing.
But he didn't care too much.
Hey thief? Haha, I didn't take a penny of cash, the only valuable thing was a mobile phone, and it was in my hand.
And what's on the screen of your phone is not a special privacy, and you won't lose a piece of meat when you glance at it.
After concentrating on a set of questions, the final result pops up on the screen: "Congratulations! It took 312.42 seconds, SSS, ranked 28 today!"
"Please keep up!"
二次 A second-dimensional girl admired the expression on the screen.
Only 28th place.
I seem to be a little bit worse than expected.
Zhang Yuan secretly said, "There are still a lot of geniuses in this world, and this ranking is normal.
If you train for a while, your performance may improve again. However, there is no need for it. He does not participate in any competitions. His arithmetic skills are almost enough.
Click on the leaderboard.
"First place, eventually eternal, 0.01 seconds."
"Second place, writing novels will eat soil, it takes 0.07 seconds."
"Third place, can you support the genuine version, it takes 0.11 seconds."
"Third place, when can I take time off, it will take 0.12 seconds."
Zhang Yuan smiled. It is impossible for humans to complete 20 questions in 0.01 seconds. These results must be made by programs after capturing information with screen reading software.
Some people like it this way. It seems that they can use their plug-ins.
It's impossible to compare the speed of the sloppy operation with that of the compulsion, and he has also lost his mind in this regard.
"Long Daqiao Station has arrived, please get off. Yuanda Industrial and Commercial Bank reminds you: Be careful when you go out, pay attention to your safety ..."
Watching Zhang Yuan leave, Ye Fan is still in a daze.
For longer calculations, his computer speed is really not as fast as the opponent's mental arithmetic speed!
谁 Who is this person? Calculating the championship?
Ye Yefan remembered the last Super Brain champion, how long it took to complete 20 questions.
"How long have you been ..."
300 seconds? 200 seconds? Seems wrong.
搜索 He searched again and 10,000 alpaca floated in his heart.
313.6 seconds!
It's just a second more than the number I just saw.
Uh ...
The attribute of intelligence is composed of three factors, namely memory, reasoning ability, and language ability. Higher.
During the entire training process, Zhang Yuan's exaggerated speed of progress also excited Zhang Yuan.
From a rusty head to a flexible head, it's just one night!
He even had another little guess in his mind: maybe ... the speed of learning other subjects is so fast!
I felt faintly in my heart, this is a kind of extravagant hope.
I became an all-around scientist like Newton. In this era, it is no longer possible.
The next Newton or the next Einstein never appeared in history. That is because the knowledge system of the entire civilization is too large and too large for the human brain to carry this knowledge.
No, it is difficult to carry even one thousandth of the amount of knowledge!
There are too many amazing and brilliant characters in history. These geniuses have laid down the knowledge system of the entire civilization.
From the first industrial revolution to the present, for hundreds of years, the whole world has undergone earth-shaking changes.
However, human's innate intelligence level has not improved much and still uses very primitive heads.
200 years ago, universities taught calculus, and universities still teach calculus. It is not that science has not progressed, but that the intelligence of ordinary people is like this.
So, modern humans are not smarter than the 21st century people, but they need more knowledge.
If you want to create new knowledge, you must first climb up the shoulders of these giants. How difficult is it?
"If it's really possible ..."
Zhang Yuan hopes to find the point of most interest, and then add some useful things to this mountain of knowledge, which is great enough.
