In the car.
After ending the call with Jiang City, Li Hongyan continued to watch the live broadcast.
"Fermi's Parabola. This little girl is quite good at asking questions.”Li Hongyan praised.
Although this little girl was asking if there were aliens? It was a question that could not be answered at the moment.
However, Fermi's Paragon was still quite good. To be precise, it was a conjecture about the existence of outsiders. Later, it developed into a conjecture with two computing companies.
The main thing was that it still needed to be calculated using mathematical calculations. This made Li Hongyan, who specialized in mathematical research, very proud.
Song Shi, who was driving, had already slowed down. He had no choice but to listen to what Jiang City's live broadcast was about.
However, after hearing that the lucky audience had been selected, Song Shi asked in puzzlement,"Master, don't you find this girl's voice familiar?”
"Familiar?"
"Yes." Song Shi thought for a moment and said,"It seems to be your granddaughter Li Yu's voice."”
"That's impossible. Not to mention whether this girl is paying attention to Jiang City's live broadcast, there are so many people, but Jiang City just had to pick him. The probability is too low.”Li Hongyan did not believe it.
"Master." Hearing this, Song Shi smiled bitterly." You might have forgotten that your granddaughter is also a programming expert. This is just a lottery function system of a live broadcast platform. If she wanted to, it would be easy for her to write a program to hack in and get a lottery slot. Moreover, although the probability is small, it's not zero.”
After hearing Song Shi's words, Li Hongyan fell silent.
As Li Yu's grandfather, Li Hongyan knew his granddaughter's temper all too well.
Although she was kind in nature, she was very proud. However, once she was interested in something, she would definitely try her best to get it through her own efforts.
Therefore, Li Hongyan had always wanted to find a grandson-in-law who could tame his granddaughter.
Unfortunately, it had always been difficult to find. However, he saw hope in Jiang City now.
In the live broadcast room:
Jiang Cheng said," First of all, let's talk about the Fermi paradox. When Nobel Prize winner and physicist Fermi was discussing UFO and aliens with others, he suddenly said,""Where are they?" The scientific topic that this question led to was known as the Fermi Paragon.
" Later, with the continuous research and the development of Fermi's Paragon, there was also the idea of using microwave radiation to detect other civilizations in the Milky Way. He proposed two equation solutions, which were called the Drake formula.”
" Of course, this is only the rough development of the Fermi Parabola. The Fermi Parabola is not perfect. Now, let me tell you how to calculate the number of alien civilizations in the entire universe.”
" The existence of extraterrestrial civilizations can be reasonably estimated using the method of elimination. After eliminating a series of harsh conditions, from galaxies to stars, then planets, and then the atmosphere, we can get a theoretical estimate of how many civilizations there are.”
After Jiang Cheng finished speaking, the young lady in the chat said,"According to this logic, it's indeed feasible, but has the host thought about the difficulties that this method will face?”
"Do you mean the huge amount of data calculation?”Jiang Cheng laughed.
"That's right."
" Well said, but I don't know if you've watched my first livestream, or maybe you didn't understand it after watching my livestream. If you do, the only algorithm I determined for the NP-complete problem in my first livestream is to directly substitute this set of calculations into it. After determining the basic values, as long as you find someone who knows how to use a calculator, you can calculate it clearly. It's really not difficult.”Jiang Cheng laughed.
After Jiang Cheng finished speaking, the other party fell silent.
Bullet comments:
"F * ck, you're not bad, Little Missy. You dare to fight with the Almighty.”
"I can see that the little sister has been attacked badly.”
"I'm afraid the host is a straight man who doesn't know how to be gentle with women.”
"As expected, there is no gender difference on the road to truth.”
"The host is single because of her ability."
"Brothers, you guys are too biased. If the answer is out, Hawking's coffin really won't be able to cover it.”
"That's right. Hawking has always been guessing that the unanswered question has been solved by the streamer. Hawking is probably going to come back to his senses.”
"There's no way he can run away from the Nobel Prize.”
"Damn it, do you have to be educated and knowledgeable to communicate with girls these days?”
................................
Seeing the other party remain silent, Jiang Cheng smiled and said,""Any more questions? If not, then I'll continue now?”
After a while, the other party replied,"Yes, we'll talk about it after you calculate it."”
Inside the car.
Song Shi was a little excited." Master, good. It really does sound like your granddaughter. The tone is exactly the same."”
"Shut up and drive."
"Oh, I know."
In the live broadcast room, Jiang City continued.
There have been very few flowers recently. Brothers, please vote more. At least it will increase to 10,000. I will also add more!
