In October, the first batch of 5,000 Poseidon superheterodyne radios was put into the U.S. radio sales market.

The current sales scale of the radio market in the United States is 10,000 units per year, so 5,000 new products is a small amount relative to the entire market, and the sales situation needs to be further observed.

Li Kangping's job was to check various reports for the first three quarters of 1923 in the president's office.

Mahjong section: sales in the first three quarters were $1.53 million, new investment (construction of Florida factory) expenditure was $280,000, employee salaries, advertising costs, production materials costs, energy costs and other costs were $980,000, and profits were $270,000.

Radio section: investment of $920,000, debt repayment of $60,000, payment of superheterodyne radio patents of $45,000, profit - $1,025,000.

R&D sector: patent fee + $1.4 million, 30 acres of land ≈ $400,000, the initial investment of $200,000 has been exhausted, and the actual working capital income is $800,000. The budget for the electronic television project was $100,000, of which $70,000 has been spent. Profit +$730,000.

Movie section: Invest $80,000 in Walt Disney Studios, profit - $80,000.

Headquarters: $170,000 in labor and miscellaneous expenses, $80,000 in repayment of Citibank loans, and $250,000 in profit.

Taken together, Manhattan Zeus has developed several projects in the first three quarters, with a negative profit of -$355,000.

If you count the 30 acres around Zeus' lab, it's slightly profitable.

But Li Kangping is not so desperate to need land now, what he urgently needs is liquidity.

Moreover, Ye Qisun has obtained a doctorate degree from Harvard University, and according to the agreement, Brother Qisun went to New York to meet Li Kangping.

Li Kangping arranged for Brother Qisun to live at his home in Queens, and he took out the manuscript of "Atomic Physics" and asked Brother Qisun to read it.

"Atomic Physics" begins with X-rays and ends with quantum theory, with a total of 210,000 words. It took Li Kangping 10 months to complete the work.

"X-rays, infrared, voltmeter, volt, roentgenium, entropy......" Brother Qisun carefully studied "Atomic Physics", he understood the physics content of this Chinese textbook, and there were many new Chinese translations in the book, and Brother Qisun considered them one by one.

Li Kangping's translation of the Chinese version of physics professional terms and physicists' names are all remarked in English.

"For example, X-RAY, translated as X-ray, X-ray, the key is unity, since Kangping is translated as X-ray, then X-ray."

"Kang Ping's translation of entropy as entropy is really a stroke of genius!" Brother Qisun stroked his palm and smiled, he was extremely satisfied with Kangping's invention of the new Chinese character "entropy".

The concept of Entropy was coined as early as 1854, but it was still a relatively new concept and could not be expressed in existing Chinese characters.

Chinese physicists basically use Entropy's foreign name directly? For physicists who are fluent in one or several foreign languages? There is almost no difference between English, German or Chinese.

Teaching local Chinese students is different, if there are professional, reliable Chinese teaching materials? Chinese teachers definitely gravitate towards Chinese textbooks.

Some Chinese translate Entropy as "can get tired"?

gy, it should not be regarded as "can".

Entropy is not energy? However, it has something to do with energy (fire), and energy is divided by temperature (quotient) to get "entropy".

"Entropy? Clever, really clever! Brother Qisun once again praised Kangping Miaochuang for the word "entropy".

After reading "Atomic Physics", Brother Qisun commented: "This book is a collection of the strengths of physics from various countries, but it is suitable for the situation of China? And with Kangping's innovation? It unifies the national terms of atomic physics and quantum theory. Kang Ping has made great contributions to Chinese physics, and the foolish brother is very relieved and happy. ”

Accompanying "Atomic Physics" are "Mechanics", "Electromagnetism", "Optics", "Thermal", and "Acoustics".

Quantum mechanics later, right? At present, the concept of quantum mechanics has not yet been born in the world.

Li Kangping has a busy business and limited time? It took him ten months to write a book called "Atomic Physics", and the remaining branches of physics? Try to finish the manuscript gradually over a few years.

Brother Qisun left with the manuscript of "Atomic Physics", and he boarded the ship to return home.

Brother Yutai, Brother Qisun and other benevolent brothers have returned to China after completing their studies? There are also new Chinese students studying in the United States.

The English version of the paper "High Energy Electron Diffraction Experiments" was published in the October issue of Physical Review? The authors are Woodgate, Mark, Allen.

Li Kangping's name appears in the body of "High Energy Electron Diffraction Experiments"? The paper claims to have completed high-energy electron diffraction experiments, and the experimental evidence obtained proves Li Kangping's theory of matter waves.

At the same time, the German translations of "Waves of Matter", "Experiments on Electron Diffraction of Nickel Crystals" and "Experiments on High-energy Electron Diffraction" were completed, and Li Kangping sent the German versions of these three papers to Einstein.

Li Kangping spent nearly two years making a meticulous strategic layout and tactical operation of the academic line of material waves.

At present, it seems that the material wave route is controllable, and its global propaganda is in line with Li Kangping's expectations.

In the academic field, Li Kangping also adopts a rolling development approach.

When the wave of matter was not yet finalized, Li Kangping rolled and developed the "Principle of Electron Spin and Incompatibility".

Regarding the "Principle of Electron Spin and Incompatibility", Li Kangping wrote back to Einstein, explaining the five difficulties raised by Einstein.

However, the thoughtful and thoughtful Einstein raised new questions, writing in his letter: "Now this spin splits each level into two, except for /2, which only moves." The diagram on the left side of the diagram corresponds to the expected result according to Sommerfeld's theory, so how should the so-called angular quantum number be defined by the magnitude of the momentum moment of the electron around the nucleus? My student Smekar is assisting me in the argument of the Electron Spin and Incompatibility Principle, and the next letter may be from Mr. Smekal. ”

"Since your new theory has some relevance to Mr. Sommerfeld's, I made a copy and sent it to Mr. Sommerfeld. There are two wonderful young men in Munich named Heisenberg and Pauli, both of whom are students of Mr. Sommerfeld, and they will work with him on your Electron Spin and Incompatibility Principle. ”

It seems that the "Electron Spin and Incompatibility Principle" is indeed an extremely complex and esoteric set of theories, so that Einstein could not figure out this set of theories alone. Albert Einstein organized a joint Berlin-Munich team to demonstrate the principle of electron spin and incompatibility. This is the situation on the German side.
