Deep Space Fleet

After a few minutes of being so excited, the same question came to mind.

"7812378 * 7812378 = ..."

Huh? ? ?

Huh? ?

I still can't make it in a second, what's going on?

As ... keke, a genius should not be made difficult by such problems!

Zhang Yuan frowned, a multiplication vertical pattern appeared in his mind, and stumbled for half a minute before jumping out of the final result.

"61033250014884."

I was okay, I still made it.

I thought about it for a moment, and a faintness appeared on his face.

"So it was ... the original me, when I encountered this kind of problem, I solved it by pressing the computer directly, so that the computing skills were greatly degraded. If you don't think about it, even a genius, you can't jump out of the answer immediately ..."

"It's slow now, just because you don't have enough proficiency and don't have the relevant skills. If you use mental arithmetic for a long time, you will get better slowly."

the next day……

Zhang Yuan woke up with sleepy eyes and rubbed his confused head.

I may be because I was too excited last night and kept measuring IQ, so I was unable to fall asleep. It was almost dawn when it finally fell asleep.

At a glance, it's 10 o'clock.

"Oops!"

Zhang Yuan rolled up from the bed, washed quickly, and then hurried out of the house.

"I hope not to be late, otherwise my aunt will miss 叨 for a long time ..."

The 30-day holiday is very urgent. Every day has a clear arrangement. Today is already scheduled. I will go to my aunt ’s house for lunch.

Donghua City in July is like a stove. The heat waves are rolling and the roadside plants are in deep water.

Zhang Yuan hurried to the subway station, where there will always be comfortable air conditioning.

不 There is no shortage of energy in this era. The power generation of each large-scale fusion nuclear power plant is comparable to the former Three Gorges Hydropower Station. The price of domestic electricity is as low as 3 cents.

Thanks to this, in addition to the original high prices of petroleum derivatives such as plastics, high energy-consuming industrial products such as steel and cement have become extremely cheap.

Especially the booming development of nanotechnology has allowed building materials to be updated from generation to generation. For a simple example, if nano-silica is added with 6% of cement, the compressive strength can be doubled, and the workability of concrete can be improved in all aspects.

The popularity of cheap new materials has made the city's surface buildings more and more high, and thousands of high-rise buildings can be found everywhere.

Put two hundred years ago, the 828-meter-tall Burj Khalifa was the tallest building in the world, but now it can only be the tallest building in the village.

And ... at the same cost, at least five can be built!

Some traffic rails are even placed thousands of meters high, with skyscrapers as the rail pillars.

这些 These are popular in almost all big cities, and the aerial track becomes the facade of the big cities.

"A lot of people."

Donghua City is one of the top five first-tier cities in Xia Kingdom. Even if the morning peak has been missed, the subway station is still crowded.

"Passengers, please treat the elderly and children."

"Do not smoke or beg in the car."

If you want to solve the traffic problem completely, that is impossible.

The sprayers can always find the most comfortable angle to attack the government. If the transportation is too crowded, the government will definitely be sprayed; but if there are too many subways and there are a lot of empty seats, it will be considered as a "waste of taxpayer money". . Anyway, it will be sprayed no matter how it is used.

Zhang Yuan was behind the team. He heard someone complaining constantly about "do not increase the number of trips" and so on. He smiled in his heart. He didn't have much thought, but picked up the phone by himself and brushed the question.

This is a very popular "Super Brain" app, which can examine a person's memory, arithmetic ability and reasoning ability. It is also boring to be idle anyway. It is also good to brush up a few questions. By the way, test your own IQ.

IQ is his most concerned issue at present.

Whenever I measure my IQ is high, the mood is so refreshing, it is hard to describe in words.

The subway station is very noisy and it is difficult to concentrate, but I don't know what's going on. Doing a question will always produce a wonderful sense of accomplishment, giving him a feeling of eating chocolate beans.

Maybe after using that potion, he has an attribute called "workaholic"?

"I finally understand why someone is willing to work day and night. It turns out to be happy. Don't do it. Using your brain has turned into a fun thing!"

Ding 咚 ...

The subway entered the station, the crowd poured in like a tide, and the area where the queue was originally emptied.

Zhang Yuan walked into the subway, found a place to stand casually, and brushed questions one after another.

Seven-digit four-digit arithmetic, with the increase in proficiency, has changed from the original half a minute to 10 seconds, and the calculation speed is increasing.

The feeling that the answer is ready to come out finally finally appeared.

The more he used his mind, the more his spirit became, and this result made him satisfied.

Soon, he began to dissatisfy ordinary four arithmetic operations and turned into square root operation.

"Let's start with a simple one, √7812 (reserve four significant digits)"

Zhang Yuanyuan made himself more difficult.

开 Manually square an integer, there are many different ways. The most common one is called test quotient, which is similar to division. As long as the mental arithmetic ability is sufficient, it can be directly calculated.

There are some algorithms that are slightly troublesome, such as continuous fraction expansion, dichotomy, Newton iteration, and so on.

After fifteen seconds, he reached a specific conclusion.

"√7812 = 88.38 ..."

The answer is correct!

"√444"

"21.07"

The answer is correct!

Oh ha ha!

Is this ... the feeling of being a genius?

I really ... Fragrant!

The car is very quiet. Except for the electronic reminder sound of the subway, everyone is busy immersing themselves in their world.

I have a few guys occasionally, I do n’t know if I watch the novel or the video and see the climax. UU reads www.uukanshu.com and ca n’t help but laugh out, just like a fool ...

"Shard time on the subway should be used to promote yourself, not entertainment!"

A "knowledge" returned from studying abroad frowned and was feeling this bad social atmosphere.

现象 The phenomenon of "low-headed people" is often criticized by major media, but it is not very useful to slam them. Everyone should play. The bow-down should not let the government legislate to ban mobile phones in public places, right?

男人 The man's name is Ye Fan. In his knowledge, everyone in the subways abroad is reading newspapers instead of playing mobile phones. His morals are a hundred times better than Xia Guo (in fact, there is no Internet).

无论 Anyway, in his impression, young people living abroad are much healthier than young people in Xia Guo!

"It's no wonder this group of people can't go to space. That's because they put their study time on entertainment ... It's strange to go to space!" Ye Fan thought secretly.

"What's the saying? I just spend the time of others drinking coffee ..."

Especially the young man wearing short sleeves around her, a honey smile appeared on her face.

Hey, should you be in love with a two-dimensional girl?

Nothing!

(First explain the title of this book. I originally wanted to name it "Deep Space Age", but it is too serious, the click rate will be very low.)

(Well, science fiction, everyone understands that although "Wandering Earth" is an explosion, it does not mean that other science fiction can also explode. Most people probably don't want to read the title of "Deep Space Era", they don't want to click on it. Click the kind.)

(Think about it instead, "Deep Space Ball" sounds very earthy, but the click-through rate should be a bit higher ...)
