Turing brought two glasses of cider to the bar, suddenly locked his eyes on Zhou Hexuan's face, hesitated for a few seconds and asked, "Zhou Hexuan's cat?" ”

Zhou Hexuan was stunned, but he didn't recognize Turing. Because the image of the young man in front of him is too bad, his hair is like a rotten bird's nest, and his beard is like a tramp, which is similar to the picture of Turing in his impression.

Seeing that Zhou Hexuan was stunned, Turing smiled and stretched out his hand: "Hello, Mr. Zhou, my name is Alan Turing, I am a mathematician, and I also study quantum mechanics and logic. I enjoyed your cat experiments, but unfortunately I didn't get a chance to meet Mr. Einstein. ”

"Hello, nice to meet you." Zhou Hexuan shook hands with the other party funny, and met the main owner inexplicably.

He was a super-genius who learned to read at the age of 3, wrote short essays in science at the age of 8, won the King's Medal in Mathematics in secondary school, and was admitted to Cambridge University at the age of 19, and became a Fellow of King's College Cambridge at the age of 23 upon graduation.

Later generations called Turing a god because he was called the "father of artificial intelligence".

Just as Zhou Hexuan was paying for the wine, Turing smiled and said, "I'm here to treat you to these two glasses of wine." Mr. Zhou, are you interested in chatting? ”

"Of course." Zhou Hexuan nodded and said.

Turing poured himself a glass of wine and asked, "Mr. Zhou, in your "Titanic", you made a bold prediction about future technology. What kind of machine does the word 'computer' refer to when you use it? ”

Zhou Hexuan said: "A machine that can perform logical operations and has the function of storing memory. ”

"How does it work?" Turing asked.

Zhou Hexuan spread his hands and said: "I'm not a scientist, I'm just a science fiction person." ”

"Well," Turing asked, somewhat disappointed, "have you read that paper of mine?" "On the Application of Numerical Computing in Decision-Making Problems". ”

Zhou Hexuan said very honestly: "Although I can't read it, I look amazing." ”

"Hahaha." Turing laughed.

"On the Application of Numerical Computing in Decision-Making Problems" is a groundbreaking paper. In this paper, Turing gave a strict mathematical definition of "computability" and proposed a model of thought that could theoretically make computers with super-computing power. It is praised by many as "the pioneering work that clarified the principles of modern computers", which is equivalent to laying a theoretical foundation for electronic computers, so Turing is also known as the "father of electronic computers".

As for the English word "computer", the etymology of "computeras" appeared as early as 1869, which roughly means "computer machine".

Zhou Hexuan's use of "computer" in the version of "Titanic" should belong to the first in ancient and modern China and abroad, and I don't know if the United States will use "computer" to name the electronic computer a few years later - it is very likely that Zhou Hexuan is the original name of the electronic computer.

Turing obviously understood that Zhou Hexuan was a layman in mathematics, and instead of talking about professional topics, he asked: "Mr. Zhou, do you think electronic computers can be realized?" What is its future? ”

Zhou Hexuan said: "As a family, I speculate purely on literary fantasy that electronic computers can definitely be realized, and its future will be artificial intelligence. ”

Turing laughed, "A robot with human thinking abilities? ”

"At least it can simulate the human mind." Zhou Hexuan said.

People with this kind of fantasy, Zhou Hexuan is obviously not the first. But to really form a scientific concept, Turing had to do it, and it would have to wait until ten years later.

One is a math layman, the other is a math expert, Zhou Hexuan and Turing chatted very happily. Zhou Hexuan is in charge of fantasizing about the future of technology, while Turing is trying to prove its achievability from existing science, and they talk for more than half an hour, while Ma Jue drinks both glasses of cider next to him.

Bletchley Gardens is still small in size, with only a few hundred intelligence workers combined, and Turing is a very inconspicuous member of the group (although he is highly regarded by the superiors, he is disdainful of veteran cryptographers). So now Turing's job is relatively easy, and he has time to brag to Zhou Hexuan, and he doesn't even live in the garden - mainly because the dormitory hasn't been built yet.

Soon it will be lively, and there will be more and more experts, as many as more than 10,000 at its peak, and more than 200 under Turing alone.

Chatting and chatting, the two talked about topics from artificial intelligence to quantum mechanics.

Zhou Hexuan naturally doesn't know anything about this, but he has read a few popular science books such as "A Brief History of Time", and any scientific idea can attract scientists of this era.

When talking about "Zhou Hexuan's cat" again, Zhou Hexuan suddenly said: "Mr. Turing, have you ever thought that God rolls dice, and every time he rolls it, it is a universe. ”

"How?" Turing became interested.

Zhou Hexuan said: "Since each quantum has a different state, and the universe is made up of quanta, it is possible that the universe is not only one, but composed of multiple similar universes. Like, in this universe, I meet you at the bar and sit down over a drink and chat. And in the other universe, I may go back to my room to rest because of something. ”

Turing apparently took this as a joke and said, "Is this called the 'parallel universe' hypothesis?" It is indeed a perfect explanation for cat experiments from a science fiction perspective. ”

Zhou Hexuan said: "I solve the cat experiment, in fact, there is a more crude and direct way. That is to find a wave function of the whole universe, and if the whole universe is part of the wave function, then there is no need for an observer. ”

This sentence was later uttered by Hawking, who was haunted by "Schrödinger's cat" for a long time, and he said that every time he heard a cat, he had the urge to reach out and pull out a gun.

Turing was stunned, and then laughed: "If anyone can find a wave function of the entire universe, then he will become God, and I am willing to be his loyal dog." ”

Ma Jue was about to roll his eyes when he heard it next to him, and he couldn't understand why Turing was laughing at all, could it be that Zhou Hexuan just said a joke?

Zhou Hexuan said: "Maybe future scientists can succeed." ”

"I hope so." Turing said expectantly.

Zhou Hexuan said: "I have a son, who is only 10 years old this year, and he is already teaching himself calculus. I'm sure he'll become a mathematician or a physicist in the future, and maybe he'll be able to solve some quantum mechanical puzzle. ”

Turing said, "If your son is studying in England one day and I happen to be teaching at that school, I would like to be his mentor." ”

Zhou Hexuan said with a smile: "Then it's decided, you have to set up a note." ”

"No problem." Turing was also a little drunk, and actually took out a small notebook from his pocket, tore it off on the spot and set up a note for Zhou Hexuan.
