Ye Fan was disdainful in his heart, and decided to go back to the office to write an article to criticize this bad phenomenon.

If you can bring up a topic and stir up a lot of heat, you can also increase your popularity by the way!

Even the title has been thought of - "The "Bowed Family" in the Subway - Jumping from the Culture of a People"

Thinking of this, he quietly pointed his mobile phone at Zhang Yuan, preparing to use the counterexample he had taken as a picture for the article.

He glanced at Zhang Yuan's phone screen again and frowned.

"Hey, I'm not in a relationship with a two-dimensional girl. It turned out to be a super brain. ”

"I can't use it for illustrations......"

Of course, he had watched the TV show that took the country by storm. The "Super Brain" app was specially developed for the audition.

Players who are confident in their intelligence can do questions on their mobile phones, and the top 1,000 people in each season can qualify for the audition. After the audition, you can go to the real scene to show your level.

Because it is an online online selection, many people will use computers to cheat, resulting in the whole result is not real. However, during the audition, these cheaters will always show their feet.

"Quick calculation, I'll do this too!"

Ye Fan spied curiously, eager to try. He also learned mental arithmetic when he was a child, and at this moment he subconsciously wanted to compare himself with Zhang Yuan.

“88.8*8+88.88*8-8.99/8.88=…… (4 significant digits reserved)"

Zhang Yuan thought for a few seconds and wrote the answer directly.

“1420”

"So fast?" Ye Fan was surprised, "Although as long as the 4 significant digits are retained, the decimal is just omitted...... That's an interesting question. ”

However, he didn't care too much, and thought that Zhang Yuan had been counting for a long time.

In the next question, Zhang Yuan pointed a little.

"ln(40) (3 significant digits reserved)"

This time, the two are on the same starting line.

Ye Fan was full of energy, racking his brains to think.

"Wait a minute, how should a logarithmic function be calculated? What is the formula for changing the bottom? ”

For a while, my head was a little messy.

Try it hard: "ln(40) = ln(4) + ln(10), and ...... Hey, no, I still can't figure it out, do you have to memorize some logarithmic table? ”

Zhang Yuan wrote the answer on the screen again.

“3.69”

"Correct answer!"

Ye Fan's eyes widened, as if he had seen a ghost.

He still hasn't figured out how to calculate logarithms, and he can't figure it out at all.

At this time, the other party starts the next question again.

"sin(24°)" (3 significant digits reserved)

What is this? How do trigonometric functions work? Double angle formula? Not right either.

sin (24°), it's impossible to calculate it by hand!

I saw that this person wrote the answer on the screen again: "0.407"

"Correct answer!"

“……”

suffered invisible blows in a row, and Ye Fan had no choice but to give up treatment.

He was also embarrassed to ask, but searched through his mobile phone and found the answer he wanted.

"I see, hand arithms or trigonometric functions require Taylor series expansions...... Alas, it's normal to count these long-term trainees! ”

He couldn't help but pout, and thought unconvinced: What's the big deal about being able to do a quick calculation? This skill is completely useless, no matter how fast a person calculates, can it be compared to a computer?

Perhaps, another article could be written to criticize those educational institutions that teach mental arithmetic, and there is no need to burden children to learn something inconsequential.

Thinking like this, he quietly took out his mobile phone in his hand, opened the computer software, and thought: If I press the speed of the computer, can't I catch up with the speed of your mental arithmetic?

Zhang Yuan faintly felt the edge of his back, as if someone was watching him, looked left and right, but found nothing.

But he didn't pay much attention to it.

Thief? Haha, I didn't bring a penny of cash, and the only valuables were my phone, and I had it in my hand.

And the things on the screen of your mobile phone are not particularly private, and you won't lose a piece of meat when you look at them twice.

After doing a full set of questions, the final score popped up on the screen: "Congratulations! The final time was 312.42 seconds, SSS, ranked 28th today! ”

"Keep up the good work!"

An admiring expression of a two-dimensional girl popped up on the screen.

It's only 28th.

It seems to be a little worse than expected.

Zhang Yuan secretly said in his heart: "There are still many geniuses in this world, and it is normal to rank this grade." ”

If you train for a while, you may be able to improve your performance again. But there's no need for that, he doesn't participate in any competitions, and his arithmetic ability is almost enough.

Click on the leaderboard.

"First place, the final eternity, took 0.01 seconds."

"Second place, writing a novel 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 ask for leave, it takes 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 the program after the information is captured by the screen reading software.

Some people like this, using plug-ins to force them to appear to be very capable.

It is impossible for a person's computing speed to be compared with the hanging, so he has extinguished his mind in this regard.

"Dragon Bridge Station has arrived, please get off. Yuanda Industrial and Commercial Bank reminds you: please be careful when you go out, pay attention to the safety of your feet......"

Seeing Zhang Yuan leave, Ye Fan was still in a daze.

For longer calculations, his speed according to the computer is really not as fast as the other party's mental arithmetic speed!

Who is this man? Count the champions?

Ye Fan vigorously recalled the last Super Brain champion and how long it took to complete 20 questions.

"How long is it ......?"

300 seconds? 200 seconds? It doesn't seem right.

He searched again, and ten thousand alpacas floated by in his heart.

313.6 seconds!

That's exactly one second more than the number I just saw.

……

Intelligence is an attribute made up of three factors, which are memory, reasoning, and language ability. Arithmetic is fast, not necessarily high intelligence, but undoubtedly means that the reasoning ability is higher than ordinary people.

Throughout the training process, the exaggerated speed of progress also made Zhang Yuan excited.

From a rusty head to a nimble head, it's just one night's time!

He even had another little guess in his mind: maybe ...... The speed of learning other subjects is so fast!

I have a faint feeling in my heart that this is a luxury.

It is no longer possible to become an all-round scientist like Newton in this era.

There has never been a next Newton or the next Einstein in history, and that is because the knowledge system of the entire civilization has become too large for the human brain to carry this knowledge.

No, it's hard to carry even one ten-thousandth of the amount of knowledge!

There have been too many amazing and glamorous figures in history, and these geniuses have laid the foundation of the knowledge system of the entire civilization.

From the first industrial revolution to the present, the whole world has undergone earth-shaking changes in hundreds of years.

But the innate intelligence level of human beings has not improved much, and they are still using very primitive heads.

Calculus was taught in universities 200 years ago, and calculus is still taught in universities today. It's not that science doesn't progress, it's that the intelligence of ordinary people is like that.

So, modern humans are no smarter than people in the 21st century, but they need more knowledge.

If you want to create new knowledge, you have to climb on the shoulders of these giants.

"If you really can......"

Zhang Yuan hopes to find the point that interests him the most, and then add something useful to this mountain of knowledge, which is already great enough.
