The all-electronic television system is a systematic project, and Li Kangping could not do substantive work for the time being, so he wrote a paper and tried to take the lead in taking action at the theoretical level of the all-electronic television system.

For Li Kangping, mechanical TV can be realized now, so he first made mechanical TV.

Theodore became the first employee of Zeus Labs, receiving a $20 a week and owning a Ford official car that the company had allotted him, which he thought was good, so he worked very hard.

"In terms of technical details, the camera disc and the projection disc have to be strictly synchronized, and that's the 'disc sync' technique, Theodore, do you understand what I'm talking about?" Li Kangping spent all day in Zeus's laboratory learning techniques with Theodore.

"Boss, I totally understand what you're talking about."

"Good."

Li Kangping draws pictures while outputting academic opinions. Theodore draws while receiving academic views.

Thirty holes were drilled near the edge of the camera disc, all 2mm in diameter. The holes are evenly arranged along an involute line, with each hole being one diameter shorter than the adjacent hole at a distance from the center of the disk. If there is an image behind a photographic disc, the image can be seen in its entirety as the disc rotates around the central axis at high speed.

Although at any given moment, only a small part of the hole is actually visible to the eye, when the disc is turned fast enough, we can see the whole picture, as if we had made a hole of the same size in the disc against the small window.

For each rotation of the Nipkov disk, an image is sent. The illuminator illuminates the object through these holes, and the reflected light is received by the photocell, converted into an electrical signal, and then transmitted to the corresponding lamp on the projection disc to obtain the picture.

Our TV signal takes the form of an audio signal, which can be transmitted using telephone lines.

In other words, if our experiment is successful, the images we take in New York will be able to be transmitted to San Francisco immediately.

"Theodore, this is our TV, our amazing TV."

"yes, that's right, oh, I'd love to make our TV right away!"

Li Kangping and Theodore worked day and night to draw design drawings and revise technical parameters.

Their mechanical TV is not a box, but a set of discs, shafts, brackets, and wires.

The design materials of the mechanical TV were finally completed, and Li Kangping ordered Theodore to follow the map and buy experimental equipment, tools and materials.

At the end of August, Li Kangping came to the auditorium of the Council of Columbia University, he gently pushed open the door of the auditorium, a lady was playing the piano in the front hall, and entered the main hall through the front hall, and the sun shone through the stained glass in the solemn hall.

More than a dozen men gathered here, the oldest being nearly 40 years old, and the youngest appeared to be Li Kangping, who was not yet 22 years old.

"Hello."

"Are you okay?"

Everyone greeted each other, they were prospective PhDs from Columbia, and they would be PhDs today.

"Doctors, put on your robes."

The staff of the Columbia Senate distributed the doctor's gowns, and the prospective doctors put on their robes and stood by in place.

At ten o'clock, the president of Columbia University and the big names arrived in the hall.

The big man sat in the big chair, and the headmaster stood next to him.

The Rector began his speech: "Gentlemen, you will receive your Ph.D. from Columbia University today. You are so outstanding, you are so dazzling, you have great wisdom and noble virtues, and your name makes us proud. ”

"Mr. Carl Jay Milton, you are persightful, your writing is smart, your style is lively, you are well-informed, you are thoughtful, you have completed a magnificent, fearless tome, a must-have book for a thoughtful man's desk......"

The Principal's warm and extremely sincere praise for Mr. Carl Jay Milton, Doctor of Education.

If you remove the name Carl Jay Milton, you'd think the headmaster was describing Professor Dewey.

The president's compliment was the reason for Carl Jay Milton's Ph.D. from Columbia.

Carl Jay Milton walked up to the principal, shook his hand, and then knelt in front of the big man and kissed the back of the big man's hand.

The big man put on a doctor's hat for Carl Jay Milton, and Carl Jay Milton took a group photo with the big man and the principal, and the audience burst into warm applause.

The reason for each Ph.D. graduation is different, and the president continued to praise the next Ph.D.: "Mr. Kang-Ping-Li, you are kind and transcendent, you are extremely intelligent and talented, your "Waves of Matter" is the most creative treasure in physics, your "Nickel Crystal by Electron Diffraction Experiment" illuminates the way for physics, and your academic ideas are like a symbiotic mine with a complete range of tastes, which contains rich spiritual treasures to feed people's spiritual needs......

Listening to this compliment, Li Kangping was really a little embarrassed.

“…… Mr. Lee, Columbia University is even more brilliant because of your presence! May God bless you! ”

Li Kangping walked up to the principal with a steady pace.

The president shook hands with Li Kangping and conferred on him a doctorate certificate.

"Mr. Li, congratulations." The principal sent his sincere congratulations.

"Thank you, Headmaster." Li Kangping responded politely.

Immediately, Li Kangping moved a few steps sideways and came to the big man.

The big man kept smiling, and Li Kangping knelt down on one knee and kissed the back of the big man's hand.

The big man put on a doctor's hat for Li Kangping, and Li Kangping took a group photo with the big man and the president, and his ceremony ended successfully.

After each doctor put on their hats, everyone took a group photo, and the doctoral graduation ceremony came to an end.

Columbia University graduates a batch of doctors every few months, and these more than a dozen doctors graduate, they study different majors, and only Li Kangping is the only one who studies physics.

Li Kangping is very popular, and many people want to recruit him into his command.

Professor Woodgate has long expressed this meaning, and he hopes that Li Kangping will continue to stay in the Woodgate laboratory and make a more brilliant academic career with him.

Li Kangping politely declined Professor Woodgate's offer, and he told Professor Woodgate that after graduating from the doctorate, he would focus on the business of Zeus in Manhattan.

China's self-funded students in the United States love to go wherever they want to go after graduation, and what they love to do, and basically all the government-funded students in the United States return to China after graduation.

Li Kangping's situation is special, and Mr. Zhou fully understands Li Kangping's special situation, so Li Kangping did not return to China as soon as he got his doctorate like Brother Debang, Brother Yue Lin, and Brother Yutai.

Regardless, getting a PhD is something to be happy about. Li Kangping invited his friends to a party to celebrate his official promotion to Dr. Li.
