Chapter 1 Notes

"Superposition state" After writing these three characters on the blackboard, Lin Sen turned to look at everyone and said: "In the macroscopic world, there is an ironclad law of cause and effect. For example, when I toss a coin, the moment it is covered is A certain value. In the microscopic world, uncertainty is the inherent property of microscopic particles. The coin is still covered, it has the front and the back facing up at the same time. We call it a superposition state. When I remove my hand, the coin is formed. The microscopic particles are quantumly entangled with the external environment and degrade from microscopic properties to macroscopic properties, so we only see the front or back of the coin."

“What is the dividing line between the macrocosm and the microcosm?”

"Our macroscopic world is made up of microscopic worlds, just like this coin, which itself is made up of microscopic particles."

After speaking, Lin Sen wrote Einstein's energy formula on the blackboard.

E=mc²

"The macro world and the micro world are different interpretations of the same world, just like the two sides of this equation, one describes mass and the other describes energy."

"Since the macro world and the micro world are different interpretations of the same world, how do we understand that the superposition state of the macro world is a parallel universe?"

"I tend to imagine the world as countless circles, and time brings these circles together. The surface of each circle is composed of countless points, if we think of each point as representing a possibility. But every two circles only have one in common This is my understanding of the uniqueness of the future, that is, there is only one universe."

After a pause, Lin Sen continued: "How do we understand the superposition state of the macroscopic world? Everyone is familiar with 'love'. Whether you like her or not sometimes depends on whether she likes you or not, and you are in a state of liking or not liking her. The superposition state of liking. Whether she likes you or not will change whether you like her or not, and the same goes for the other person. When I know you like her, I also know that she also likes you. This is quantum entanglement. "

"Isn't this love at first sight?"

"There is also a clear understanding of the heart."

In the corner, Zhou Zhiqi wrote the word "Lin Sen" in his notebook.

"Didi..." The crisp ringtone entered the ears, breaking the tranquility of the mountains.

"Siwo, results, record." Chen Zhang whispered. A beam of weak light shot out from the glasses, passed through the pupil, and put a grid line on the sheep a hundred meters away in the retina. There was a small red dot under the neck of each sheep, and three sets of data were displayed by beating next to it. . In the empty space of the scene, an information box appeared, which read: Test quantity 100, test duration 1 hour...

"Statistical data is 6000, and the allowable error value for the same longitude and latitude is 1cm. 61% of the recorded altitude values ​​have deviations less than 10cm, 18% have deviations between 10-100cm, and 21% have deviations greater than 100cm."

As the system finished broadcasting, Chen Zhang pressed the pause button in the air and dragged the generated results into the virtual folder numbered 0108. Then he closed the Siwo system interface, stretched out, and looked at the sheep in the distance again. , fell into deep thought.

In the office, as the 0108 folder is opened on the display screen, the red "X" in the upper right corner is extremely eye-catching. "It failed again. Do you think this altitude problem can be solved? Our leader's perseverance and perseverance are admirable." "When the longitude and latitude coordinates increase in altitude, we will move from two-dimensional plane positioning and navigation to three-dimensional navigation. The new era of spatial positioning and navigation is exciting to think about." Sun Rui sighed, and then said: "It makes me want to help herd sheep."
