When Li Kangping was an undergraduate in the previous life, his teacher told him that in the high-speed, microscopic field, the theory of relativity and quantum mechanics were the guiding ideology. And in the low-speed, macroscopic field, the classical theory is still valid. We recognize the centrality of relativity and quantum mechanics, and we also recognize the academic value of classical theory.

But in 1922, people's thinking was limited, and their understanding of many issues was not so comprehensive and profound.

Li Kangping has been accompanying Arthur Compton to discuss academics these days.

Arthur Compton was initially a proponent of classical theory, and in 1919, his brother Carl Compton published a paper on the quantum of light, which had an impact on Arthur Compton, who became a supporter of the quantum theory of light.

In the autumn of 1920, Arthur Compton met Li Kangping, and with his help, Li Kangping's first paper, "Black-body Radiation and Light Quantum", was published. At the same time, "Blackbody Radiation and Light Quanta" inspired Arthur Compton, who immediately went into action when he returned to Washington University in St. Louis to design and complete X-ray scattering experiments.

No one is born a new school, a radical, such as Arthur Compton, a physicist who was influenced by others in the course of his academic research, and his academic thinking gradually changed from the old school to the new school.

"Arthur, when is your paper expected to be submitted to the Physical Review editorial board?" Li Kangping asked.

"I'll arrive at my hometown in Ohio tomorrow and type out my paper, which I'll probably deliver to Physical Review on my first day as a physics professor at the University of Chicago."

"Arthur, I wish you all the best."

"Lee, these days have passed quickly, and pleasant times have always passed quickly. This meeting with you was very rewarding, and I am grateful for the fact that you helped me finalize the draft and strengthened my resolve. ”

"Arthur, I hope that when you go to the University of Chicago, try not to provoke Mr. Michelson."

"Okay, I'll try."

"Arthur, I'm a little puzzled, there are so many universities in the United States, why did you deviate to the University of Chicago? Mr. Michelson is the chair of the physics department at the University of Chicago, and you meet him every day. ”

"If I don't go to the University of Chicago, will Mr. Michelson disappear from this world?"

"Oh, Arthur, I can't argue with your damn logic! All in all, good luck. ”

"Good luck and goodbye too."

Li Kangping said goodbye to Arthur Compton and went to Zeus's laboratory.

As a result of technical improvements, the resolution of the Zeus Lab television setup has been increased to 48 lines at fifteen frames per second.

In the previous version, the playback screen of the TV receiver was recessed inside the receiver and could only be seen by one person. Li Kangping: After making technical changes, they projected the TV picture onto the screen in front of the receiver in a similar way as a slide projector, so that multiple people could watch the live TV broadcast at the same time.

Late Saturday night, Fifth Avenue Rhodes & Taylor Department Store closed. Manhattan Zeus transported the television installation overnight to the first floor of the Rohde & Taylor department store.

Li Kangping personally went to the scene of the television performance and instructed all departments and units to install and debug the television equipment.

"Theodore, Alex, this is a mall, not a lab, please try to gather the wires together as much as possible, fix them on the ground with tape, and don't make this place look too messy!"

"Mr. Fox, I hope you can increase the number of people who maintain order in the mall tomorrow."

Li Kangping was busy and communicated closely with his own team and the mall team.

The television installation was installed and commissioned, with a male employee of Zeus in Manhattan acting as a temporary model.

In an instant, the facial image of the male employee was projected on a screen 20 yards away, and the size of the picture was slightly larger than Li Kangping's palm, and the clarity of the picture had improved to a certain extent.

"OK, call it a day, let's rest for a while---- in fact, we can only rest for more than two hours." Li Kangping twisted his arms and twisted his waist, these days are indeed very hard.

"Dr. Lee, I think your television should be of great interest to New Yorkers. I'm a New Yorker, and I'm obsessed with your television. Manager Fox said excitedly.

"Mr. Fox, I'm so grateful to your mall for providing a space for TV performances, and I hope our cooperation can continue, on the TV side, or otherwise."

"I want to have a chance, don't I?"

"Thank you. Now, let's take a nap, and after dawn, we'll be put to the test by the citizens of New York. ”

The crowd squinted in the mall for a while, and when they opened their eyes, the morning sun rose.

Early in the morning, almost all the employees at Zeus Corporation headquarters in Manhattan came to the Rhodes & Taylors department store.

Lead photographic model Jennifer wore a blue dress and a dark hat with a flower pinned to it, dressed as dignified and playful.

"You know, photographic models are important, and our Jennifer is as beautiful as a movie star, and I think it's easier for the citizens to accept." Li Kangping smiled, "I don't want to make any monster TV movies, what I want to shoot is a beauty show." ”

"I hope I won't let you down." Jennifer's skillful seating camera chair warms up customers before they enter the store.

The staff of the mall who came before the customers came.

Manager Fox greeted the mall staff in advance and said that there would be a TV show in the mall today.

Although they were mentally prepared, the mall staff were still surprised to see this TV set.

"What is this? Is this what TV? ”

"Look, the image of this beautiful young lady appears on the screen!"

"That's right, I saw her, it's her!"

"She takes off her hat, she puts it on!"

"Oh, Lord, this is not a movie, this is a real-time picture!"

"Can anyone tell me how exactly this is done?"

"I've discovered the secret! You see, the machines at both ends are connected by telephone lines, and the secret of the TV is actually the same as the telephone! ”

"Oh, you're so smart, so why didn't you invent a TV? And I don't think a machine that transmits a real person's picture is the same thing as a telephone that transmits a person's voice! ”

"All in all, Dr. Lee's invention is incredible!"

The staff of the mall stopped to watch, and there was a lot of discussion, and there was a heated discussion.

"Hey, everyone!" Manager Fox clapped his hands vigorously and shouted, "Back to your work, in twenty minutes, the mall will be open, and I ask you to do whatever you normally do!" Your curiosity will be thoroughly satisfied after the mall closes, and Dr. Lee will even allow you to be a model photographer once! And now, please do your job, thank you! ”
