The disadvantages of the ore machine are obvious, it has poor sensitivity, it is often on the stage, and it can only be listened to by one person through headphones.

After the advent of vacuum transistors, they were used to make radio signal amplifiers. After the advent of the reed horn, it became the speaker of the radio. At present, in the radio market in the United States, ore machines with headphones and repeaters with speakers coexist.

It is said that after Li Kangping submitted a patent application for a super regenerative circuit, he immediately returned to Chenbian Heights.

Savvy and capable, he is well-versed in finance, taxation, financial business and many other businesses.

Li Kangping has made up his mind to hire Liu Shaowen to help him manage the Manhattan Zeus Company.

Manhattan Zeus appears to be an American company.

Our boss is Chinese, and the boss's most trusted partner is also Chinese.

Our boss, partner, migrant worker or migrant girl can't all be Chinese, I have to hire a few Americans to pretend.

So, Li Kangping found his American friend, Miss Jennifer Johnson.

"What happened in the past year?" Jennifer was very emotional, she said: "This time last year, you just came to the United States, you didn't understand anything, and you hired me as your English teacher. At this time of the year, Mr. Li, you are already a doctoral student and experimental assistant at the Columbia Graduate School! And I didn't even graduate from my bachelor's degree. Can you tell me what's going on? ”

Li Kangping smiled, and he asked, "I said Jennifer, can you graduate this fall?" Or is it next spring? ”

Jennifer said: "I'm working on a dissertation and I'll be graduating in November this year. ”

"Essays on English Literature or French Literature?"

"French Literature."

Jennifer majored in literature, a high discipline.

Li Kangping asked again: "So Jennifer, do you plan to continue graduate school or seek a job?" ”

"I'd better look for a job, yes, I need a job that makes ends meet, you know, the cost of living in New York is high."

"Jennifer, can I hire you?"

"You don't need an English teacher, do you?"

"Jennifer, do you have time to accompany me to East Harlem now?"

"East Harlem? All right. ”

Li Kangping drove Jennifer to the King Tower in East Harlem, parked the car, and led Jennifer up to the fifth floor of the King Tower.

"Jennifer, as you can see, this is the company I own."

"What? Your company? You actually opened a company! ”

"Please, starting a company is not a new thing, some people at Columbia University have opened dozens of companies, and everyone is opening a company these days."

"Manhattan Zeus, the name is quite loud."

Curious, Jennifer visited the offices of Zeus Corporation in Manhattan, where she saw a full range of office furniture and supplies, but did not see any employees.

"So, Lee, what about your employees?"

"Isn't this hiring?"

"What kind of business does Manhattan Zeus do in business?"

"We have a New York State trade license and can do everything you know about regular trade."

"Uh-huh, that sounds good."

"Jennifer, I would like to know, is there a chance I can hire you as a staff member of the Zeus Corporation in Manhattan?"

"Lee, are you serious?"

"Yes, I mean it, I promise."

"Oh, let me think, let me think about it."

Jennifer looked here and there, looking hesitant.

Although the women's sports are vigorously carried out in the United States, there is more or less gender discrimination in the American workplace today.

Most of the young girls who have not gone to university are engaged in positions such as counter salesmen and shop assistants.

Girls who have gone to university have the opportunity to work in government departments or medium-sized and large-scale enterprises as secretaries, typists, stenographers, etc.

Manhattan Zeus, it looks good, but it doesn't have a single employee other than a Chinese boss.

Can this company grow, and to what scale?

Who knows, it's impossible to predict.

Companies that are already in operation and have a reputation are certainly a safer job option.

Jennifer hesitated.

She had a hard time making a choice.

Li Kangping said bluntly: "Jennifer, I am willing to pay you a weekly salary of $20, what do you think?" ”

"Hmm...... You make me think about it, you make me think about it again......"

"Okay, you think, I'm making coffee."

"Hmmm......"

Oh, $20, it's not $8 or $10, it's a $20 a week job.

Employees who have worked in a medium-sized company for several years and have some work experience can get a weekly salary of $20.

The average police officer in New York City earns less than $20 a week!

Not long ago, police officers in New York went on strike to protest against low salaries.

Jennifer witnessed the police strike march and knew that $20 was definitely not a very low pay.

Yes, it is almost difficult for a girl who has just graduated from college to get a job with a salary of $20 a week.

"Lee, it's common for you to hire me as your English teacher. But it always feels a little weird that you hire me as an employee of your company. ”

"Jennifer, it's okay, if you don't want to, forget it, it's no big deal."

"Li, I am willing to accept this job, thank you for giving me this job."

"Yes, Jennifer, that's what you think?"

"Yes, it's true."

"Then you can start working now, if you don't delay writing your paper. And I will pay you from the day you go to work. ”

"Boss, you're such an efficient person!"

"Jennifer, we all know that you are a serious girl, and our company is a serious company, so you should sign an employment agreement with our company. But as you can see, our company is in the early stage of entrepreneurship, and the company's rules and regulations need to be further improved. Actually, the employment agreement for our company is not yet written. Li Kangping said, "Jennifer, since you are majoring in literature, then I think it is not too difficult for you to help our company draft a personnel and employment agreement, what do you think?" ”

Writing an essay requires a typewriter, as well as some references.

Since we have a typewriter in our office in East Harlem, and I can bring the literature with me—it's not a hard task, just a few books. So there's no difference between me writing my thesis at Barnard College and writing my thesis in my office.

Miss Jennifer Johnson began her job as Senior Secretary in the Office of the President of Zeus Corporation in Manhattan.

In fact, there is only one open-plan office.

The Office of the President, the Office of the Vice President, the Office of the Chief Financial Officer, the Office of the Business Manager, and the Office of General Staff are all located in this office.

Since our company is in its infancy, this situation is understandable and acceptable.

Jennifer brewed coffee and tasted it comfortably.

In fact, Jennifer has yet to receive her Barnard College diploma.

What's so bad about being able to get a $20 a week while you're studying? Who would be willing to say no?

Jennifer pores through the business materials in her office.

"Leiden-Cohen Company, the predecessor of our company, Mr. President acquired Leiden-Cohen Company through legal means and changed its name to Manhattan Zeus Company."

"HR employment agreement? How should this be written? ”

"Oh, that's great! Leiden-Cohen has ready-made documents for this, so I'll change Leiden-Cohen to Manhattan Zeus and copy it. ”

Click, click.

The clever Jennifer used the resources available to her to prepare various regulations, agreements, and contracts for the Manhattan Zeus Company.

"Leiden-Cohen is also a new company, and it has only been established for a year."

"And our company has been listed for five months, and it doesn't seem to have made a single trading business?"

"It's also normal, after all, we didn't have any employees in our company before. Without employees, of course, it is impossible to do business. ”

"A company without operating income can't last long. So what kind of business does our company want to do? ”

"This can't be a shell company, right?"

Jennifer fell into deep thought.

Oh, whatever, Mr. President will have a way.

At this moment, in the apartment on Chenbian Street, Mr. President is drafting his third thesis.

The wave-particle duality of light was proposed by Albert Einstein as early as 1905 and 1916, and was demonstrated by Milligan's photoelectric effect experiments in 1916.

The theory of wave-particle duality of matter particles needs to be demonstrated.

Li Kangping believes that regardless of the outcome of this year's Solvay conference, he should first write out the theory of wave-particle duality of matter particles.

[Part I: Waves and Quantum.] 】

[Energy = h× frequency is a quantum relation that relates a periodic phenomenon to any isolated part or energy of an object. An observer on the object associates the object with a frequency that depends on the internal energy of the object, which I call 'static mass'. 】

[I calculated that the internal periodic motion is in phase with a wave with a frequency of ν=m0c^2/h√1-β^2.] This relation of frequency comes from the quantum relation and makes use of the total energy of the moving object---- as long as the wave is assumed to propagate with velocity c/β. I must point out that the speed of this wave is greater than c and it is impossible to carry energy. 】

"Wait a minute."

The wording here needs to be revised. I must say that this is too much of a ...... It's too arrogant, it's not appropriate. ”

"It should be changed to, I'm pretty sure, that the speed of this wave is greater than c, and it can't carry energy."

Click, click.

[We should think of radiation with frequency ν as the motion of many light atoms with very small masses (<10^-5g), whose velocity is very close to that of c as can be seen from the equation m0c^2/√1-β^2=hν. The light atom slips slowly on the immaterial wave with a wave frequency of ν and a velocity of C/β slightly greater than C. 】

Li Kangping was engrossed in typing, and he particularly liked the first part of the paper, "Waves and Quantum."

"Waves and quantum" has proposed many new concepts, and these new concepts may change the development trend of science and technology and the process of human civilization.
