In this era of fierce confrontation between old and new theories, many physicists' academic ideas fluctuated from left to right, including top figures such as Bohr.

Bohr did not threaten and intimidate Li Kangping, he just put forward his current academic view, and he supported the wave theory of light.

"Regardless, I appreciate your contributions to the theory of space quantization." Bohr looked at the time on his watch, and he was about to meet the next physicist.

Li Kangping politely retired, he did not intend to convince Bohr, and he could not convince Bohr to support the Compton effect or matter waves at this time.

As for the Poseidon Radio Company, General Manager Sanders told Li Kangping: "Dr. Li, considering the opinions of consumers, wholesalers, and suppliers, they believe that Poseidon brand superheterodyne radios are high-end commodities, and the retail price should not be less than $60 per unit. ”

"Where's the ceiling?" Li Kangping asked.

"The average U.S. household income is $1,000 a year, and that hasn't changed in years. Radios are becoming a household necessity, and a repeater sells for dollars, a price that the vast majority of American households can afford. The U.S. radio market sold $60 million in 1922 and sold 1.5 million repeaters, which can be simply understood as the purchase of repeaters in 10,000 American households. Judging by the current sales figures, it is very likely that the sales of the radio market in 1923 will exceed 100 million US dollars! In other words, the radio market is trending for the better. In such an environment, I think it is reasonable that our superheterodyne radios are priced at least $60 at a retail price. But it's not too high, preferably not more than $70 per unit. Sanders made his suggestion.

Li Kangping paced back and forth, hesitating.

After a long time, Li Kangping made a decision: "The retail price of the Poseidon brand superheterodyne radio is set at 69.9 US dollars. ”

"It's a bit high, but it's worth a try." Sanders agreed to a retail pricing of $69.9.

Li Kangping asked again: "So what is the appropriate wholesale price for wholesalers?" ”

"In order to stimulate the enthusiasm of wholesalers, we should give them a profit point that is a little higher than the profit point of their wholesale repeaters now, and I think 20% is more appropriate. That is, the price of the wholesaler to batch with us is in US dollars. Of course, it's different in every state, but the retail price of $69.9 is our recommended price, and wholesalers buy in dollars, and they can sell it to consumers for $65 or $75, depending on the state they are in, the city. "Saunders has a lot of business experience, and he clearly states the business model and the rules of the industry, both explicit and implicit.

"John, now we are unified in the Caliber?$69.9 retail price is called the 'official guide price'. I see what you mean? Wholesalers may not be able to implement the 'official guide price' 100% in the consumer-facing retail link after taking the goods. Is this understandable? After all, there are differences in laws, tax rates, social customs, and economic levels in various states in the United States. All in all? We don't require the 'official guide price' to be $69.9 at the retail level, we just supply the wholesalers at a flat wholesale price in US dollars. ”

With the determination of retail price and wholesale price? Li Kangping was both excited and nervous.

The production cost of a superheterodyne radio is $21, and if the wholesale price is set at dollars? Then the profit after tax is around $32. Let's pray that Poseidon radios are selling well.

Li Kangping received an invitation letter? The Rockefeller Foundation invited him to participate in the American version of the "Bohr Festival Performance."

The Landmark Plaza Hotel in New York is a magnificent white building where the Bohrs stayed during their stay in New York. The Rockefeller Foundation chartered the banquet hall of the Plaza Hotel as the venue for the "Bohr Festival Performance".

Bohr's itinerary is full and he is about to visit Canada? This "Bohr Festival Performance" is also equivalent to a send-off party arranged by the Rockefeller Foundation for Bohr.

Is the Rockefeller Foundation most interested in medicine? They sponsor many medical programs.

In addition to other scientific projects other than medicine, the Rockefeller Foundation is also willing to invest in sponsorships.

Bursting with applause, Bohr took to the stage and delivered his speech: "The Copenhagen Institute for Theoretical Physics is an international academic research institution. There are only seven Danes, and the rest of the scholars come from all over the world. May I say that? The Copenhagen Institute brings together the best young physicists in the world, and I'm 38 years old? I'm the oldest person in the institute. In recent years, I am glad to see that a large number of outstanding young people have emerged in the American physics community. Like Mr. Arthur Compton?. Mr. Lee? I hope more young American physicists will come to Copenhagen......"

Li Kangping's feeling is that the current Copenhagen Institute is similar to a postdoctoral mobile station, the institute does not have the function of issuing degrees, and most of the scholars who go to work and study at the institute are recent doctors of physics from European and American countries.

A few days ago, when Li Kangping had a private chat with Bohr, Bohr personally said that the thoughts of the young people of the Compton brothers and Li Kangping were terrible.

At this time, in public, Bohr praised Arthur Compton by name. Lee is an outstanding representative of the younger generation of physicists.

Either Bohr's personality was unstable, or Bohr spoke in a measured manner, and he made very different statements on different occasions.

“…… Thank you to the Rockefeller Foundation for your generous grant to the Copenhagen Institute, thank you! ”

At the end of Bohr's speech for a few minutes, a gentleman from the management of the Rockefeller Foundation came to Bohr's side, and the two of them jointly held a check for the audience to show to the audience, and the amount on the check was $100,000.

With this $100,000 funding, Bohr will be able to build the Copenhagen Institute more complete and advanced, and then recruit more outstanding young people to Copenhagen and join the Copenhagen School.

The European version of the "Bohr Festival Performance" is a pure academic exchange, while the American version of the "Bohr Festival Performance" has a certain academic nature, and more importantly, it seeks sponsorship in the name of scholarship and expresses gratitude to the sponsors.

The band began to play, and the guests were free to move around and socialize.

Li Kangping saw Bohr passing his eyes ten yards away, and walked over.

"I don't read every article in every issue of the magazine, but I happen to have read all of your published articles." "As a theoretical physicist, I'm most interested in the article 'Waves of Matter,' and it's hard for me to judge the universality of Waves of Matter," Bohr said, "but I prefer to believe that particles of matter are wave-like." ”

Bohr favored the wave theory of light, and he questioned the particle nature of light.

At the same time, Bohr favored the wave nature of matter particles, and he seemed to support the theory of matter waves.

According to common sense, if you support wave-particle duality of matter particles, then you must also support wave-particle duality of light.

But Bohr didn't think so, and his scholarship was complex and strange.
