From the Top Scorer in the College Entrance Examination to the Overlord of Science and Technology

The main thing is to use mathematical calculations to calculate it, which makes Li Hongyan, who specializes in mathematical research, very proud.

Song Shi, who was driving, has slowed down the speed of the car now. There is no way, he still wants to hear what Jiangcheng said on the live broadcast.

But now, after hearing the lucky audience who was selected, Song Shi asked suspiciously, "Master, do you think this girl's voice sounds familiar to you?"

"Familiar?"

"Well." Song Shi thought for a while and said, "It seems to be the voice of your granddaughter Li Yu."

"Impossible, not to mention whether this girl has followed Jiangcheng's live broadcast. With so many people, Jiangcheng has chosen him, and the probability is too low." Li Hongyan didn't believe it.

"Master." Hearing this, Song Shi said with a wry smile: "You may have forgotten that your granddaughter is still a programming expert. This is just a lottery function system for a live broadcast platform. If she wants to, write a program to hack into it and get a lottery place. It is not an easy thing, and although the probability is small, it is not a possibility of 0."

After hearing Song Shi's words, Li Hongyan fell silent.

As Li Yu's grandfather, Li Hongyan is too aware of his granddaughter's temper.

Although she is kind in nature, she is very arrogant, but once there is something she is interested in, she will definitely try to get it with her own efforts.

So Li Hongyan always wanted to find a grandson-in-law who could take care of his granddaughter.

It's a pity that it has always been difficult to find, but now in Jiang Cheng, he sees hope.

Studio:

Jiang Cheng said: "First of all, let's learn about the Fermi paradox. When Fermi, a Nobel Prize winner and physicist, was discussing the issue of flying saucers and aliens, he suddenly said, "Where are they? "The scientific question raised by this question is known as the "Fermi Paradox".

"Later, with the continuous research and the development of the Fermi Paradox, the astronomer Frank Drake proposed two equation solutions based on the idea of ​​microwave radiation to detect other civilizations in the Milky Way, known as the Drake formula. ."

"Of course, this is only an outline of the development of the Fermi Paradox of Science. The Fermi Paradox cannot be said to be complete. Now I will tell you how to calculate how many alien civilizations there should be in the entire universe."

"The existence of alien civilizations can be reasonably estimated by the exclusion method. After a series of harsh conditions such as galaxies, stars, planets, and atmospheres are excluded, we can get the theoretical number of appearance civilizations."

After Jiang Cheng finished speaking, the sister in the channel said: "According to this logic, it is indeed feasible, but has the anchor thought about the difficulties faced by this method?"

"Do you mean the huge amount of data calculation?" Jiang Cheng laughed.

"Yes."

"Well said, but I don't know if you have watched my first live broadcast, or you may have watched my live broadcast and didn't understand it. If you know something, I answered it in my first live broadcast before. The only algorithm determined by the NP-complete problem of , is that this set of calculations can be directly substituted into it, and after determining the basic values, as long as someone who can use a calculator can calculate it clearly, it's really not difficult." Jiang Cheng laughed.

After Jiang Cheng finished speaking, the other party went silent.

Barrage:

"Fuck, sister can do it, dare to fight with the great god."

"It can be seen that my sister's body is completely broken by the counterattack."

"The anchor is afraid that he is a straight man and doesn't understand Lianxiangxiyu at all."

"Sure enough, there is no gender distinction in the search for truth."

"The anchor is single by strength."

"Brothers' style of painting is biased. If the answer comes out, Hawking's coffin board really can't be covered."

"No, Hawking has always guessed that if the unanswered question is solved by the anchor, Hawking is afraid that he will return to his dream."

"The proper Nobel will have to run away."

"Damn, do you have to have education and knowledge to communicate with girls these days?"

................................

Seeing that the other party was silent, Jiang Cheng smiled and said, "Is there any problem? If not, then I will continue now?"

After a while, the other party replied: "Well, let's talk about it when you figure it out."

And inside the car.

Song Shi was a little excited: "Master, okay, it seems that it is really your granddaughter's voice, the tone is exactly the same."

"Shut up and drive your car."

"Oh, I know."

In the live broadcast room, Jiang Cheng began to continue.

ps: The fifth update has been sent. Recently, there are very few flowers. Brothers vote more. Anyway, it is a bit of a face to rise to 1. I will add more!

In addition, ask for flowers, ask for monthly tickets, ask for evaluation tickets, ask for rewards, ask for reminders, ask for comments and chat.

===036 Li Yu who refuses to admit defeat ===

Jiang Cheng's voice sounded in the live broadcast room.

With our current observable universe, the space is [-] billion light-years, and the number of galaxies has reached [-] billion. Of these more than [-] billion galaxies, almost every galaxy is as big as the Milky Way.”

"According to Fermi's speculation and calculations, the stars in these galaxies are conservatively estimated to be [-] billion to nearly [-] trillion. We calculate that only the minimum value is taken, which is [-] billion"
