Chapter 460

Alice clearly remembered that they rushed into the fog in a lifeboat, and then met a savage on the island. Mrs. Larry suffered as a result. Pardik and other sailors were eaten by savages, and only she and Anderson escaped.

She told Aoki and suhuilan all this. There would be no problem, but how many days have passed? She never calculated accurately. It felt like a few days.

But she was suddenly unsure, and her memory suddenly became blurred, as if she had just had a dream.

Alice's face looked painful and muttered to herself, "why can't I remember! Why can't I remember!"

Su Huilan held her shaky body and said: "That's because there is no standard sunrise and sunset on the island, and the length of day and night is unstable. Our brain only counts time according to our own biological clock. Objective memory can't help us understand time, but confuse our brain. So when you don't think about this problem, your intuition is that after a few days, you will find that there is no time at all With time memory, the brain has determined that these are invalid information and thrown them into the information garbage. "

Situ nodded and said, "that's right, so it's difficult for us to estimate the exact time we spent on the island. I said it took several months because I simulated an atomic clock in my dream."

"Atomic clock?" said Su Huilan, "can you simulate the decay of microscopic particles in your dream? It's incredible!"

"In fact, it's not difficult. You can also do it. The only problem is that you need to understand the principle of the atomic clock and the resonant frequency of the atom you want to use in the energy level transition." situ gently waved his hand and said, "it's just that I participated in the design of the world's first cesium atomic clock and witnessed its success."

"The first cesium atomic clock was built in the late 1950s. Aren't 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. If according to her father, he was the best member of the young generation of the alliance and the successor of master Nanke, it means that he was already an excellent young man when master Nanke was alive, and master Nanke Disappeared during World War II.

If situ really participated in the design of the first cesium atomic clock, the time would coincide, but she really can't imagine that this handsome man with romantic style and superstar temperament is already in his 70s and 80s?

"Yes, the atomic clock of that era was so heavy that it needed a big house to fit it, and it was not easy to build it." situ neither denied nor acknowledged Su Huilan's words, "But if it's in a dream, it's much easier. You can even omit the tools and steps used to cool or heat cesium atoms, and you don't need the lasers that lift cesium atoms and the sensors that capture them. Everything is done by consciousness.

We only need a suitable energy field to let cesium atoms pass through repeatedly and transition between two different energy levels to make its resonance frequency reach 9192631770hz, so that a conscious atomic clock is ready.

The atomic clock is the most stable timer. The definition of second has long existed in human history, but it has not been able to accurately measure and calibrate it. It was not until 1967 that people redefined second as 9192631770 times the period of the electromagnetic wave radiated during the transition between the two hyperfine energy levels of the ground state of cesium 133 atom. This definition is determined by the almanac in astronomy The second of meaning is equivalent, and there is an error of about one second every 20 million years.

However, the requirements for the environment of the atomic clock are too high. It requires the cesium atom to be cooled to a static state near absolute zero first, and magnetic field interference is not allowed in the whole energy level transition process, but in the real world, the universe is full of magnetic fields and rays. However, all this is different in dreams. The dream space is composed of the subconscious, which can shield all interference. "

Aoki finally learned how they felt when they listened to situ's strange talk about the physics of mirrors capturing light. He knew nothing about the atomic clock, but after hearing situ's talk, he felt like it was the same thing, but Aoki couldn't do it even with Aoki's mental power if he wanted to be one in his dream. Because the atomic clock was not so understated as situ said, if he wasn't proficient It's impossible to simulate such a thing in atomic physics and have personally studied the design scheme of atomic clock. It's like it's not difficult to simulate the effect of a nuclear bomb explosion in your dream, but it's impossible for non professionals to simulate an atomic energy reactor.

Even he was puzzled, and others were confused. What spiritual power, dreams, consciousness and so on were like arabian nights for Alice and others.

Su Huilan is the only one who 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, everything is created only by consciousness. The cesium atoms in your atomic clock are also created by your subconscious mind. Isn't its frequency also variable at will? How can you determine that the second you define is correct?"

Situ said, "the so-called vibration frequency is actually the radiation generated during the energy level transition. It is a kind of wave, and the wave can be captured by consciousness. It can interfere with our mental force, and our mental force also exists in the form of wave. I have felt the pulse of cesium atom in the atomic clock at a stable frequency, so I can engrave the same pulse in my dream."

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

"It's not difficult. We often use the combination of dreams and specialties. Engineers can use dreams to design drawings, and physicists can use dreams to simulate the motion of celestial bodies. In the era of no computer, things that are difficult to be displayed intuitively on the plane can be made through dreams, which is just more spiritual. Many geniuses I know do so Yes, you can. "

Situ said and smiled at Su Huilan, "However, Professor Su does 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 God in a dream. Of course, the dream failed because he was God in the dream, and one world could not tolerate the existence of two gods. In addition, he also simulated the solar system in a dream This time, it was very successful, and therefore put forward the theory of nebula, which was written in his general history of nature and theory of celestial bodies. "

Su Huilan had to admire situ's erudition. This idea really inspired her. The subconscious can create the world, but it can't be separated from memory. However, a madman like Kant wants to create God in his dream. This is not only wishful thinking, but also a kind of innovative wisdom and rebellious courage.

Of course, Su Huilan would not be easily misled by situ. She returned to the atomic clock and asked:

"But Mr. situ, the time of a dream is not consistent with the reality. There is a Chinese idiom called 'a dream of a sorghum', which means that a person has experienced a tortuous life and finally finds that he has only had a dream and the rice in the pot is not cooked when he wakes up. The length of time in the dream only depends on the speed of nerve signal transmission in our brain. How can you pass through the atoms in the dream Clock to determine the time of the real world? "

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