Therefore, Mr. Sa Bendong referred to American textbooks but did not copy American textbooks, and he combined with China's national conditions to write "General Physics".

Li Kangping feels that the earlier the Chinese version of physics textbooks is published, the more conducive it is to the cultivation of Chinese physics talents.

Combined with China's national conditions and the academic information in his memory, Li Kangping carefully wrote "Atomic Physics".

[Chapter 1: X-rays.] 】

[In 1895, Wilhelm Röntgen discovered X-ray, which was a major advance in physics, helping mankind understand the basic patterns of matter, and also saving lives in the field of medicine......]

The Chinese translations of many Western scientists were translated during the Republican era and continued into the 21st century.

Wilhelm Röntgen was Chinese translated at this time as Roentgenium, Langzan, Jungway...... There are several translations, depending on the translator's preference.

Karl Marx is translated by more Chinese names, Zhu Zhixin is translated as "Marke", Liang Rengong is translated as "Buried Clam Division", Duxiu Gong is translated as "Kamashi", and "Beijing Daily" is translated as "Maikashi...... Until recently, Karl Marx was unified by Zhao Gong as "Max".

To avoid trouble, Chinese physicists often use foreign names when talking about Western scientists and physics terms.

Li Kangping felt that the name Roentgen was the best, so he adopted the translation of Roentgenium, wrote it in his book, and noted the German name of Roentgen.

The X-Ray discovered by Roentgenium was orally translated as "X-ray" by Ye Qisun and Rao Yutai.

Li Kangping changed it to "X-ray" and wrote it in the book.

The value of "Atomic Physics" lies in its theoretical knowledge of physics suitable for China's national conditions, and also in the unification of the Chinese translation of physicists and physics professional terms.

【…… X-rays can discharge charged bodies. The charged body in the air, whether positively or negatively, is discharged by X-ray excitation, and its process speed is proportional to the intensity of the rays......]

Compiling textbooks is not an overnight effort, and Li Kangping writes a little bit every day, which adds up to a lot.

The New York Daily News reported a piece of news: "In 1922, radio sales in the United States reached $65 million, and everyone was no longer talking about wireless telephone technology, but about radios." Every night there is music coming out of the radio in various cities, and anyone can listen to the radio at home, and any boy can install an ore radio in an hour. ”

"President Harding installed a full listening device in the White House study, the Dixmore Golf Club let the golfers hear the church sermons on the radio, the passengers on the Rackwana train listened to the concert on the radio, and Lieutenant Maynard modernized Christianity because he radioed the Easter sermon on the plane."

"A very popular song appeared during this time, describing a man who wanted his lover to hear his confession on the radio, and this song even challenged the popularity of Siegfried's "My Passion Rose". Whoever you meet on the street, he will forcibly hold you and tell you how he stayed up until 1 a.m. last night with headphones on his head and actually heard the voice of Havana, the capital of Cuba! ”

"Yes, everybody uses the radio, everybody loves the radio."

The New York Daily News objectively reported on the current state of radio in American society. In fact, Li Kangping had the idea of a radio a long time ago, he didn't have the strength to do the radio business before, but now, he has it.

It took too long to build a new radio factory.

So Li Kangping decided to buy a radio company.

There are specialized financial investment companies in the United States, and there are several on Wall Street. These financial investment companies are similar to intermediaries, they do not do the business of housing or nanny brokerage, but the intermediary of company acquisition.

Li Kangping entrusted Liu Shaowen to contact Wall Street financial investment companies, and he hoped to use the resources of these financial investment companies to acquire a radio company at a suitable price.

Liu Shaowen was puzzled at first, our mahjong business is still in the climbing stage, and Zeus Laboratory is still in a situation of zero income, Kangping, but you want to do a radio business?

"Brother Shaowen, please believe me. If the mahjong business is stable and Zeus Lab is profitable, it may take a few years and will inevitably miss business opportunities. Starting a radio business at a time when the mahjong business is profitable but not at its maximum, I call it rolling development. Li Kangping explained.

"Rolling development?"

Although there are doubts, Liu Shaowen still trusts Li Kangping.

Liu Shaowen took his finance team, which connected with the financial investment company on Wall Street.

Li Kangping continued to write Atomic Physics.

Ye Qisun and Rao Yutai called the voltage measurement device "voltameter" and "fudameter".

Li Kangping changed it to "voltmeter", and unified the physical measurement units of "volt" and "futa" into "volts".

[The shadow of the hand bone, the shadow of the wrapped metal wire wrapped around the wooden scroll, and the weight sealed in the box, the magnetic needle of the voltmeter is completely enclosed by the metal, and the X-ray makes the metal inhomogeneity obvious......]

With the development of the New Culture Movement, vernacular writing became popular in China. The vernacular of the early twenties was actually a mixture of semi-vernacular and semi-literary, and the style in which Li Kangping wrote his book can be said to be the whitest vernacular of this era.

Liu Shaowen's work efficiency was very high, and two documents were placed in front of Li Kangping.

Fact 1: Rayleigh & Hansen Radio Company, located in Pittsburgh, manufactures ore machines and repeaters, covers an area of 20 acres, and currently employs 375 people (due to poor management, the company has laid off 375 employees from 561 to 375 and continues to lay off employees). The boss of the company intends to transfer 50% of the company's shares, and the investment capital is about 30~500,000 US dollars.

Fact 2: East Bay Radio Company, located in South Jersey City, produces ore machines and repeaters, covering an area of 36 acres, and was originally a company with more than 1,000 employees and 132 employees. The company's current financial situation is extremely dangerous, and the boss wants to transfer 100% of the shares, and the acquisition capital is about 12~150,000 US dollars. If the Eastern Bay Radio Company is acquired, it will have to assume a debt of $460,000 owed by the company.

"Brother Shaowen, my willingness is to acquire the Eastern Bay Radio Company. However, the statements of the financial investment company should not be fully believed, and Brother Shaowen took advantage of his friends in the banking circles to conduct a second investigation into the Eastern Bay Radio Company. Although Li Kangping was interested in acquiring the Jersey City-based radio company, he maintained the necessary caution before the actual operation.

Li Kangping is bold and aggressive at the strategic level, and at the tactical level, he is extremely careful.

Therefore, Liu Shaowen, in accordance with Li Kangping's tactical instructions, secretly launched a second investigation into the Eastern Bay Radio Company.
