After this meal, Armstrong was not interested in working with Li Kangping.

So Li Kangping decided to cultivate applied science and technology talents by himself, and he called the president's office of the King Building: "Jennifer, Zeus Laboratory needs to be set up, set up some tables, chairs, filing cabinets, and blackboards, and arrange them according to the model of a ten-person office." Let the General Management Department do it, quickly. ”

In 1920, Li Kangping enrolled in three courses, atomic theory, electromagnetism, and calculus. He got to know some of his classmates in the big classes and tutorials of these three courses.

After some inquiry, Li Kangping locked up a few classmates, and he went to the master's dormitory building of Columbia University.

Li Kangping, who had lived in the master's dormitory for a while, and his former room was now occupied by someone else, knocked on the door of another master's dormitory on the same floor.

The door opened, and the owner of the dormitory, a white boy with brown hair, said with some surprise, "Lee, why are you here?" ”

Li Kangping smiled: "Theodore, how are you doing lately?" Can I go in and sit? ”

"Please come in."

Theodore welcomed Li Kangping inside, and the room was in a mess, and it looked like Theodore was packing his luggage.

"So, Theodore, you're ready to leave, aren't you?"

"Yes, I'll go to Pittsburgh and get a job."

Theodore enrolled in a course in electromagnetism in 1920, and he enrolled in Columbia's graduate school in the spring of 1921, having just earned a master's degree in science from Columbia.

"I want to get a job in Pittsburgh and have a secure life, and I want to do a PhD at the University of Pittsburgh."

There are many people like Theodore in the United States, who are eager to learn, but due to economic constraints, they can only study while working.

"Theodore, I heard that your master's thesis was about a Nipkov disc?" Li Kangping asked.

"You're really well-informed, yes, I've been experimenting with the Nipkov disc for more than ten months. It was a painful but happy time, and luckily, my experiment was successful and I got my master's degree. Lee, I heard you're about to get your Ph.D.? ”

"You know, the big guy went to Canada for the summer, so I'd kiss the back of the big guy's hand in late August or early September and ask the big guy to put on a doctor's hat for me."

Theodore said enviously, "Oh, congratulations. I think I can call you Dr. Lee. ”

"Theodore, I want to take you somewhere--- if you will."

"Huh? Where? ”

"My lab."

"Your lab?"

"Yes, my lab, its name is Zeus Laboratory."

"Zeus Laboratory?"

"yes, interested in checking it out?"

"Why not."

Theodore showed great interest, and Li Kangping drove Theodore to Queens.

Queens is a very large borough and its residents are mostly ordinary working people and poor people. After passing through several residential neighborhoods under construction, the car arrived at Zeus Laboratory.

The 80,000-square-foot factory of Zeus Lab stands here alone, surrounded by open space and scattered with a few trees.

"Lee, this is your Zeus lab?"

"yes, that's it, let's go in and have a look."

Li Kangping took out the key, opened the door, and entered with Theodore.

In accordance with Li Kangping's requirements, the General Management Department arranged a corner of the laboratory as an office area, and there was nothing else in the laboratory except for office furniture and stationery.

"Li, your lab won't be empty, will it? Not only is there no one, but there is not even the most basic experimental equipment. Is this a lab? I think it's like an abandoned factory! Theodore said disappointedly.

"Yes, it used to be a button factory, our company rented it, and we're going to transform it into a state-of-the-art physics lab in Queens."

Li Kangping picked up the chalk, walked to the blackboard, and said, "Theodore, I want to talk to you about the Nipkov disc." You find a chair and sit down, and if I can't impress you in half an hour, you can leave at any time. ”

Theodore sat down, and he said, "Lee, you're famous at Columbia, and you've been described by professors as a physics genius, so I've followed you here." I could spend a whole day communicating academics with you, let's talk, tell me what you think of the Nipkov disc. ”

Li Kangping drew on the blackboard, and he said as he painted: "In 1884, Nipkov registered a patent in Germany, called the 'electric telescope', this electric telescope is actually the earliest Nipkov disk, the image signal is sent point by point, and if you want to send a complete image, you need to scan it. ”

"The Nipkov disc has a number of small holes in an involute around the perimeter of a disk, and as the disk rotates, the image is scanned sequentially, and the light passes through the small holes in the disk to convert the image into a series of electrical signals. The Nipkov disc is a mechanical scan, which is actually the basis of a mechanical scanning television system. Speaking of this, Li Kangping paused for the time being.

"Please, what you're talking about is literature, yes, it's the literature I borrowed when I was writing my master's thesis." Theodore spread his hands and said, "Lee, I'd like to hear more creative content." ”

"Mr. Nipkov's invention of a mechanical scanning device transmits very blurry images. In my opinion, the Nipkov version of the Nipkov disc cannot be considered a real TV, and what we are going to do is to invent a real TV, right here, in our Zeus laboratory. Theodore, do you think I have an idea for that? ”

Theodore was stunned for a moment, and then said loudly: "It's really creative, but what about the specific technical details?" Lee, your verbal creativity can't move me--- at most it attracts me. Details, I need more details, please give me more details. ”

Li Kangping smiled: "Next, we entered the technical details discussion session of 'the world's first real mechanical scanning TV'. ”

In the discussion of technical details, Li Kangping proposed the concept of "disc synchronization" technology, mentioning speed, resolution and frequency.

Theodore heard a lot of new things, or rather, new technical concepts.

The two spent a whole day in the laboratory, and when night fell, Theodore was completely moved by Li Kangping's idea of "the world's first real mechanical scanning TV".

"Lee, I'm willing to serve Zeus Labs." Theodore expressed his attitude.

"Theodore, I want you to go to Miss Jennifer Johnson tomorrow morning on the fifth floor of the King Tower in East Harlem, and she'll have the General Management Department provide you with an employment agreement, and all you have to do is sign the employment agreement. Theodore, your weekly salary is $20, is that acceptable? ”

"Oh, $20, who's going to say no to a $20 a week job?"

"Theodore, nice to work with."

"Boss, you have the final say."
