Alice clearly remembered that they rushed into the fog in a lifeboat, and then met a wild man on the island. Mrs. Larry suffered because of this. Paldick and the other sailors were eaten by the wild man. Only she and Anderson escaped. .

She had told Qingmu and Su Huilan about all this, there would be no problem, but how many days have passed in between? She had never calculated it accurately, and it felt like it was just a few days.

But she was suddenly not sure, and her memory suddenly became blurred, as if she had just had a dream.

A look of pain appeared on Alice's face, and she muttered: "Why can't I remember! Why can't I remember it!"

Su Huilan held her crumbling body on the side and said, "That's because there is no standard sunrise and sunset on the island, and the length of day and night is also unstable. Our brains only use our own biological clock to keep time. Not only can objective memory be impossible. It plays a role in helping us recognize time, but it makes the brain’s thinking confused. So when you don’t think about this problem, you intuitively have passed a few days. After you think deeply, you will find that there is no memory of time at all, and the brain has already determined These are invalid information and thrown into the information trash heap."

Situ nodded and said: "That's right, so it is difficult for us to estimate the exact time we were on the island. I said that after a few months, it was because I simulated an atomic clock in my dream."

"Atomic clock?" Su Huilan wondered, "Can you simulate the decay of microscopic particles in your dreams? This is incredible!"

"In fact, this is not difficult, you can also do it. The only problem is that you have to understand the principle of the atomic clock and know the resonance frequency of the atom you want to use during the energy level transition." Situ waved lightly. Started and said, "It just so happens that I participated in the design of the world's first cesium atomic clock, and also witnessed its success with my own eyes."

"The first cesium atomic clock was built in the late 1950s, so are you..."

Su Huilan has been hesitant to ask Situ about the person in her dream. He is too similar to the person her father left in her dream, but he is too young. According to her father, he was once a young man in the league. The most outstanding member of the generation is the successor of Master Nanke, so when Master Nanke was alive, he was already an excellent young man, and Master Nanke disappeared during World War II.

If Situ really participated in the design of the first cesium atomic clock, then the timing would have coincided, but she could hardly imagine that this handsome man with superstar temperament and succulent in front of her was already seven and eighty years old?

"Yes, the atomic clock of that era was so heavy that it needed a big house to fit in. It was not easy to build." Situ did not deny or admit Su Huilan. "But if it is in a dream, it is much easier, and it can even be omitted. The tools and steps used to cool or heat cesium atoms are removed, and there is no need for lasers to lift cesium atoms and sensors to capture them. Everything is done by consciousness.

We only need a suitable energy field to allow cesium atoms to repeatedly pass through and transition between two different energy levels to make its resonance frequency reach 9,192,631,770Hz, so that an atomic clock of consciousness is completed.

The atomic clock is the most stable timer. The definition of the second has long existed in human history, but it has not been able to be accurately measured and calibrated. It was not until 1967 that people redefined the second as the transition time between the two hyperfine energy levels of the ground state of the cesium 133 atom. The time is 9,192,631,770 times the period of the radiated electromagnetic wave. This definition is equivalent to the second defined in the astronomical ephemeris, and an error of about one second occurs every 20 million years.

However, the environmental requirements for atomic clocks are too high. It requires cesium atoms to be cooled to a static state close to absolute zero, and magnetic field interference is not allowed during the entire energy level transition. But in the real world, the universe is full of The magnetic field and rays. But all this is different in dreams. The dream space is composed of subconscious minds, which can shield all interference. "

Aoki finally learned what Moyu felt when they listened to Situ talk about the physics of the mirror capturing light. He didn't know anything about atomic clocks, but after listening to Situ, he felt that it was like that, but he wanted to have one in his dream, even with Aoki's mental power. Because the atomic clock is by no means an understatement as Situ said. If you are not proficient in atomic physics and have personally participated in the design of atomic clocks, it is impossible to simulate such a thing. It's as if you want to simulate the effect of a nuclear bomb explosion in your dream, but it is not difficult to simulate an atomic energy reactor for non-professionals.

Even he was puzzled, and the others were even more confused. What kind of mental power, dreams, consciousness, etc., were like a fantasy for Alice and others.

Su Huilan is the only one that everyone can understand, but she still has doubts: "Mr. Situ, I still don’t understand that the resonance frequency of cesium atoms is fixed in nature, but in the dream world, everything is only made by consciousness, in your atomic clock. The cesium atom was also created by your subconscious mind, so isn’t its frequency also arbitrarily variable? How can you conclude that the second you defined is correct?"

Situ said: "The so-called vibration frequency is actually the radiation produced during energy level transitions. It is a kind of wave, and the wave can be caught by consciousness, and it can interfere with our spiritual power. Our spiritual power is also a wave. It exists in the form of. I have felt the pulse of cesium atoms in the atomic clock at a stable frequency, so I can reproduce the same pulse in my dreams."

"I didn't expect you to be able to unify things in the conscious world and the physical world so highly. I have never tried this before." Su Huilan was very impressed.

"It's not difficult. The combination of dreams and professions is a means we often use. Engineers can use dreams to design drawings, and physicists can use dreams to simulate the motion of celestial bodies. In the age without computers, those that are difficult to visualize on a flat surface. Everything can be made through dreams, which just consumes more energy. Many geniuses I know have done this, and so can you."

Situ said and smiled at Su Huilan, "However, Professor Su is doing philosophical research, and may not have much contact with physical simulation, but many philosophers in history have also used this method. For example, Kant tried to simulate in dreams. God~lightnovelpub.net~ Of course this dream failed, because in the dream he himself was God, and one world could not tolerate the existence of two gods. In addition, he also simulated the evolution of the solar system in his dream, which was very successful this time. , And therefore proposed the Nebula Theory, which was written in his "General History of Nature and Celestial Theory"."

Su Huilan had to admire Situ’s erudition. This idea really inspired her. The subconscious mind can create the world, but it can’t escape the memory. However, a madman like Kant wants to create God in his dream. This is not only a whimsical idea, but also an innovation. Wisdom and rebellious courage.

Of course, Su Huilan would not be easily led by Situ, returning the question to the atomic clock just now and asking:

"But Mr. Situ, the time and reality of dreams are not unified. There is a Chinese idiom called'Huang Liang Yi Meng', which refers to a person who has gone through a tortuous life, and finally realized that he had only had a dream and woke up. When I came, the rice in the pot hadn't been cooked yet. The length of time in the dream only depends on the transmission speed of nerve signals in our brain. How can you determine the time in the real world through the atomic clock in the dream?"

Situ smiled and said, "Don't you know the real dream?"
