Chapter 542 Come, Dry up This Bowl of Ganges Water

Keyboards are pretty much the same all over the world, and even the dedicated keyboards in the library don't differ much in layout from this laptop's keyboard. Pi stared at the keyboard for a while, then quickly pressed the first key.

Zhang Zian was peeping through the crack of the door. Although he couldn't tell which key π was pressing from his position, the general position should be the number area of ​​the keyboard, which is the row above the 26 English letters—after all, this laptop Computers do not have a dedicated keypad area.

Therefore, Zhang Zian couldn't see it, but he could guess what π was hitting—it must be pi again.

Why does π use pi? Is it for relaxation? Just like humans can relax by playing games?

If he remembers correctly, the default search engine on the browser's homepage has a limit on the data length of the search bar, and it cannot be typed indefinitely.

Sure enough, π soon opened his mouth in amazement, stared at the screen, repeatedly pressed a certain number on the keyboard with his fingers in vain, but he couldn't type the number.

"Squeak!"

After failing several times, it held its head in both hands as if anxious, and picked up the short fluff on the top of its head with its ten fingers, like a high school student troubled by esoteric math problems.

Zhang Zian thought for a while, then went down the stairs gently on tiptoe, and then went up the stairs at a normal or even heavy pace, so that π could hear his footsteps and not be frightened.

He pushed open the door of the living room, walked in stretchedly pretending not to know anything, and said to himself, "It's been so hard to finish the work, I'm really tired..."

π has already left from the computer, sat on the sofa next to it, and pretended to be reading a book, but unfortunately it forgot to close the browser before leaving.

Zhang Zian sat back in front of the computer and stared at the screen pretending to be surprised, "Hey, I remember closing the browser before leaving..."

As expected, the search engine's search bar is the long string of pi numbers.

"Squeak!"

Like a child who did something wrong, π lowered his head and covered his face with his hands, waiting for Zhang Zian's scolding.

"Is it the browser opened by π? π is so smart! Other elves don't have this ability, only π can use a computer." Zhang Zian praised it unexpectedly.

"Squeak?"

pi put your hands down,

Staring blankly at him.

"I'm serious, look at that African gray parrot that claims to know all languages, it can't even use a mouse, let alone accurately type the top 100 digits of pi." He bad-mouthed Richard behind his back.

In fact, he doesn't know whether the top 100 digits of pi printed by π are correct, but it doesn't matter, as long as it can strengthen its confidence.

"Squeak!"

Pi smiled happily, holding the book in one hand, and patted his chest with the other.

Zhang Zian carefully figured out what it meant, and asked tentatively, "Pi means that you can not only hit the top 100?"

"Squeak!"

Pi nodded vigorously.

"Uh... so how many digits can π play?" He asked curiously, "200 digits?"

Pi shook his head and stretched out his arms.

That means... bigger than 200 bits?

"That's 500?"

"Squeak!"

π still shook his head proudly, his arms stretched out as if he was doing radio gymnastics stretching.

"Uh..." Zhang Zian tried to guess again, "1000 people?"

"Squeak!"

π's actions were even more exaggerated, apparently to make him guess at larger numbers.

Unbelievable, Zhang Zian was sweating a little. He didn't know how many digits of pi can be recited by humans at the longest. He couldn't imagine how this infinite non-recurring number was memorized, so he guessed again: "10,000 digits?"

"Squeak! Ho Ho!"

π's expression was a little anxious, and his movements became more hasty, as if he thought his guess was too small.

"Okay..." Zhang Zian felt that it would be a waste of time to add ten times and ten times. Since π is so confident, let him say a big number.

"10 million bits?"

He spit out this number nervously, for fear that he would overestimate and hurt π's self-esteem. This number is impossible for human beings to recite anyway, because it has exceeded the physiological limit of human beings.

Assuming that you recite ten numbers per second and recite 8 hours a day, it will take a month to recite the 10 million numbers.

"Squeak!"

π still shook his head, Xiaotiao raised his arms, letting him continue to guess.

Zhang Zian: "..."

Even if he believes in π, he can't help but wonder if it likes bragging as much as he does.

It happened that the laptop was on, so he checked it on the search engine. So far, the value of pi has been calculated to 60 trillion digits after the decimal point.

"Squeak!"

Seeing his suspicious face, π patted his chest anxiously, and waved the unnamed book in his hand.

"You mean, you can't do it on your own, but as long as you have this book, you can do it?"

Zhang Zian already understood π's expressions and movements to some extent, and he could guess almost the same. After all, π is a young monkey, as innocent and easy to understand as human children.

Pi nods.

"Okay, then I'll make a bigger guess." Zhang Zian chose to believe it. After all, π is the only elf with a golden finger that has appeared so far. Of course, the golden finger is the scarlet unnamed book.

Pi nodded expectantly.

"1000 trillion bits?"

This is his last guess, and even if he still fails to guess correctly, he is not going to guess further, because he doesn't know what the larger counting unit is, and guessing again will only show timidity.

For a moment, π's expression didn't change, just when Zhang Zian thought he had guessed right, it grinned and continued to shake its head.

Zhang Zian raised his hands, "I surrender, I really can't guess. Just tell me π."

"Squeak!"

π scratched his head and gestured, as if unable to express his inner thoughts. Finally, it clenches its free hand into a fist and then loosens it a little, as if it were gripping something and then slowly letting go.

What does it mean?

Zhang Zian was stunned. After all, he is not an expert in sign language, and the π sign is not standard sign language either.

"Squeak!"

π jumped off the sofa, holding the untitled book in one hand, leaning on the floor with the other hand and ran to the storage room. After a while, it staggered on two feet like a human, and came back with a bag of litter.

Zhang Zian didn't know what it was going to do, so he watched quietly.

π tore open the bag of cat litter, dumped some on the table, then grabbed a handful of cat litter, let them slide down from the palm of his hand, and motioned for Zhang Zian to see.

Zhang Zian became more and more puzzled, he was asking how many digits of pi can be written by π, and what does it do with cat litter?

Seeing that Zhang Zian didn't understand, π grabbed a handful of cat litter again, and continued to let them slide slowly from his palm.

Zhang Zian seems to have seen similar movements in movies and animations - it's like someone grabs a handful of yellow sand and lets it slide from between his fingers, blown by the strong wind and scattered in all directions.

Wait a moment!

Zhang Zian suddenly had an idea, and a bolt of lightning exploded in his mind, illuminating the darkness! He remembered that one of the counting units seemed to be related to "sand"! But that unit is just too big to be hopeless...

"Is it as vague as the sands of the Ganges River?"

When he said these words, even he couldn't help but tremble, and even got goosebumps all over his body.

The number of sands in the Ganges is a term derived from Buddhist scriptures. It is a double metaphor. Assume that each grain of sand on both sides of the Ganges represents a Ganges, and the product of the sands of the Ganges and the sands of the Ganges is the number of sands in the Ganges. It's hard to express exactly how big that number is, roughly just think of it as immeasurable.

"Squeak!"

π finally nodded. It was so excited that it held up the unnamed book and danced, as if it was happy that Zhang Zian guessed it right. This also means that it can write pi to an infinite length, and even to the end of time, which is longer than the life span of the universe. Length——How long is the infinite non-repeating decimal of pi, as long as π can be written!

Zhang Zian didn't know what it was like. On the one hand, he was deeply shocked, and on the other hand, this number was too exaggerated to dispel his doubts—does π really know how big an astronomical number the Ganges Sand Number is?

The big question is... what is the use of this?

Generally speaking, in common calculations in high school and college, you only need to record pi as 3.14. Even if it involves calculations in some industrial fields, you only need to take the first 10 digits of pi. More accurate scientific fields Calculations only use a few hundred digits of pi, so what's the use of being infinitely more accurate?

Human beings can recite pi to tens of thousands of digits, they can apply for the Guinness Book of World Records, they can become famous, they can become Internet celebrities, they can attract girls at parties, and maybe they can make money by publishing a book that teaches you how to improve your memory. What's the point for elves? It can't be to pretend to be aggressive in front of other elves, right?

Whether it is a human or an elf, doing things requires meaning and purpose, and it also needs to pay attention to cost performance. Obviously, reciting pi to infinity is the least cost-effective way to pretend to be coercive, because no one knows whether you are reciting it correctly.

π didn't think so, it was deeply proud, and with the untitled book in its hand, it squeaked and circled happily in the living room.

Zhang Zian's eyes fell on that book, the answer must be in the book - even π himself admitted that without that book, it would not be able to recite pi to infinity.

This is a book about life, the universe and everything, and if that's true, it must include pi.

It's useless to guess any further. When π trusts him enough, he will definitely ask π to show him the contents of this book. It's best to write in the book when he can find a girlfriend...

He looked at the time, it was time to make tea for the old tea.

"π, wait for me for a while, I'll go back when I go." He said, then walked into the kitchen, took a pot of cold water from the tap, and put it on the gas stove.

He just wants to drink this bowl of Ganges water to calm down.
