Chapter 138 Hertz
The history of quantum is a book as thick as a dictionary. The purpose of Zhu Cheng's dialogue is of course to create a quantum computer, and this quantum computer is the key to the rapid improvement of Venus' computing power. He firmly believes in this.

This book is a second-level book. It is only a simple introduction to quantum. It is a reference book that can build quantum computers. Zhu Cheng does not have a deep study of physics. If he wants to understand quantum, understand quantum, and use quantum, It is a very difficult event!

"I don't need to say much about quantum. It's a subject that shakes the foundation of physics. Treat it with caution." Trieste said while registering.

"He may shatter the myth of classical mechanics, shatter the belief of physicists, and make people unacceptable. At this point, you must be fully prepared! Traditional logistics scientists may roar loudly and let you Get out of physics!"

After Triest finished speaking, he materialized the book into reality, with a few large characters written on the wooden dark brown cover.reveals the status of quantum mechanics.

"God's joke."

"God played a huge joke on people and handed classical mechanics to everyone! Then scientists switched from believing in God to believing in classical mechanics. However, quantum theory collapsed people's beliefs. The difference between the microcosm and the macrocosm , so that people often jokingly say that this is the area that God forgot to paint."

After Triest smiled and disappeared at the counter, Zhu Cheng nodded and opened the first chapter, which is electromagnetic waves.

And Zhu Cheng began to read books with relish, and searched for relevant knowledge about quantum mechanics on the Internet. Compared with various awkward terms for electromagnetic waves, the first thing Zhu Cheng saw was a long list, which was longer than Zhu Cheng. Sincere imagination.

The first thing that catches the eye is Hertz.

This is the frequency unit of electromagnetic waves. Electromagnetic waves have become the most important part of life. They are used for calls, networks, and medical treatment!It broke through the deep forest, flew over the vast desert, crossed the misty canyon, crossed the turbulent sea, and conveyed information in the world.

The distance between people is shortened, the distance is reduced, and the earth is turned into a global village. Electromagnetic waves have contributed a lot!

The German town of Karlsruhe in 1887.This used to be the birthplace of "The Last Lesson". It witnessed the reshaping of Germany's glory, and it also shed the tears of the French. Karlsruhe, a place far away from the hustle and bustle of the world and where you can do research quietly, was born in Helmholm Z and Karl Benz.

Helmholtz is the founder of the law of conservation of energy, and the Helmholtz equation has been passed down in the long river of time, contributing to the theory of electromagnetic waves.And Karl Benz is the king of automobiles and the founder of Mercedes-Benz.

Next to the mysterious and ancient Black Forest is the University of Karlsruhe.The university lay quietly between the forest and the river, and countless radiating roads gathered and scattered like spider webs.

The 30-year-old Hertz was fiddling with his experimental equipment in the laboratory. It was an electric spark generator composed of an inductance coil, a battery, a large copper ball, and a small copper ball. On the other side was a receiver for two small copper balls.

According to his calculations, when the voltage rises to 2 volts, the air in the two small balls will be broken down, and the charges will pass through the clusters, and come and go between the two Datong balls, thus forming a high-frequency oscillation circuit. What I want to observe is the receiving device of the small copper ball.

These things were placed on a long table made of solid wood, and Hertz’s mentor was also observing. This is an important basis for proving Maxwell’s theory, and it is also a powerful proof for Helmholtz’s equation.

When the circuit was connected and a faint spark appeared on the receiver, Hertz's name was engraved in the hall of fame of the history of science along with the spark!Became the first name on the foundation list of quantum science, for the first time, light was summarized into electromagnetic waves, and the phenomena of focusing, straight forward, reflection, refraction and polarization of electromagnetic waves were verified.Proved the theory that when atoms are excited by the impact of electrons and emit spectral lines, the energy is separated.

Six years later, Hertz suffered from granulomatous vasculitis and died in this quiet city. His two daughters were not married because of the war, so Hertz had no offspring.

During the war, Hertz's wife chose to migrate from Germany to the UK, and important scientific research materials were also discarded. The photos of the electromagnetic wave experimental device that proved the beginning of quantum also disappeared without a trace. Now people can only use his circuit diagram Replicate this experiment.

36-year-old Hertz died young, but opened the quantum door to science!

In 1899, a 20-year-old Italian on holiday in Lombardy, Marconi read through Hertz's thesis, and then sent radio signals through the Atlantic Ocean, realizing real-time communication between the two places, bringing mankind into a new information age .

Did Hertz take into account the enormous commercial potential of electromagnetic waves?Maybe, maybe not.However, Hertz would never care about the so-called economic value. He is a pure scientist, and the constant pursuit of truth is the most important thing in his life.

During the onset of granulomatous vasculitis, it would be accompanied by a huge headache. In such pain, he was still thinking about the unresolved photoelectric effect.

Perhaps he is more suitable for strolling in beautiful lakes, rivers, and forests, thinking about issues that ordinary people cannot understand.Discuss projects with students on a leafy campus.

Zhu Cheng closed the book and glanced at the back garden of Gemini, the biological laboratory surrounded by gardens.He is working hard to build a garden and create peace, so that Kerui can shield him from the wind and rain in front of him, and cut through the thorns and thorns!Escort for the following scientific research!

Cree's terahertz communication is also based on the discovery of Hertzian electromagnetic waves, and a stable high-energy terahertz radiation source is an important issue that fetters the ten major technologies of the future of mankind.

On the day when Zhu Cheng's KOOF crystal was born, this problem has been solved, and the only ones who hinder the promotion of terahertz technology are those profit-seeking capitalist groups.

"Zhao Ling, prepare a press conference. The Ministry of Industry and Information Technology encouraged private funds to enter the telecommunications industry in 2013, but there has been a lot of noise and little rain. Others are afraid of the Big Three. Career is not afraid now!"

Zhu Cheng was talking to Zhao Ling who was working hard, Zhao Ling nodded and answered.Cree's official website, forums, Zhandun APP, and Zhiyan are the first to create momentum to promote Cree's terahertz communication.

"The dawn of a new era, we see the arrival of video communication!"

This is Cree's promotion. This promotion is based on video communication. The topic of video calls from 3G to 4G, and then to 4G+ has not been realized until now. The main reason for restricting video calls is traffic charges and network speed. Low.

With the continuous improvement of the network speed, the traffic fee is also increasing. In the past, if the traffic was not turned off in the past night, the loss was 50 yuan.Now that the traffic is ignored overnight, it may be necessary to give a suite to the communication giants.

So this video newsletter is hyped every time and never really arrives.Few, other than a handful of people, will use the technology for conference calls, and even more so for augmented AR communications.

"As the first pilot, we will open the first pilot in the mountain city, and again, this project has the support of the state. This is the dawn of a new era! Calls are all free! This is a new chapter! Augmented AR reality Communication! This is the new future! No more worrying about buffering!"

His declaration undoubtedly caused the whole world to fry.As for watching video buffering, it happens all over the world that the video is downloaded overnight, and the success falls short.And this high-profile declaration naturally attracted the attention of GF!Cree fans also started a heated discussion on the forum.

"This is going against the sky! Terahertz communication technology, the legendary technology that won't freeze when watching movies! Can this be successful?"

"The three giants of communication have already cried to the toilet, envious of the people in the mountain city! We have entered the post-communication era ahead of schedule! No longer will we worry about phone bills!"

"Shancheng people have something to say, we have been using free WIFI for several months! Since several months ago, we have been watching movies without data!"

"To be fair, when Zhu Cheng was about to hold a press conference, my heart trembled. My wallet, which had finally bulged up, was about to collapse again. Did anyone chop their hands? Count me in!"

"I'm envious of the welfare of the mountain city, my uncle Dang slaps me in the face every day, Zhu Cheng seems to have really come back!"

……

None of this disturbed Zhu Cheng, who was debugging a terahertz instrument. Terahertz technology is called a forgotten treasure because on the electromagnetic spectrum, infrared and microwave technologies on both sides of the terahertz band are already very mature, but terahertz Technology is basically still a blank.

The reason is that the electromagnetic waves in this frequency band are in the transition zone from macroscopic classical theory to microscopic quantum theory, and from electronics to photonics.Its frequency is higher than that of microwaves and lower than that of infrared rays; its energy is between electrons and photons.Because of this cross-transition region, terahertz is not completely suitable for treatment by optical theory, nor is it completely suitable for study by microwave theory.Once forgotten.

What Zhu Cheng wants to improve is the problem of ultra-short and super-strong laser targets, and this target is divided into small-sized metal targets, metal-polyethylene (PE) composite targets, polyethylene targets and other target types of transition Radiation research.

The light spot effect of the laser metal solid will generate a strong thermal electron flow is also a huge challenge, and this terahertz instrument needs to replace the target every day. , There are great disadvantages to the large-scale promotion of terahertz technology.

But materials science requires a lot of experimentation.It takes super bad luck to get some specious results.Know what to do, but know why to do it.And this problem, Zhu Cheng wants to solve it satisfactorily!
