Li Kangping continued to read the letter, and Lorenz's letter was very important.

"Lee, there is a transcendental insight implicit in your conception. In this insight, the concept of waves is reverted to the first place as a feature of authenticity, and one might think of associating the energies of the individual units of the intrinsic mass m0 with the periodic phenomena of the frequency ν0 thanks to a great law of nature. Based on this idea, we can learn that there is no difference between particles and their phase waves in terms of physical realism. If we were to do a one-to-one correspondence, we would seem to see the following conclusion: our dynamics (known in its Einstein form) lag behind optics, and statics is in geometric optics. If it seems true enough to us today, the various fluctuations represent the concentration of energy, and the dynamics of a particle undoubtedly hides a wave propagation ......"

Lorenz explores scholarship in the first half of the letter, and the second half relates to academic conferences.

“…… Everybody has seen your paper, and there may be a lot of people who have written to you to exchange academic questions, just like you and I have exchanged letters. Writing a letter is a private matter between two people, and I still hope that physicists will discuss clear results on important academic topics such as matter waves, electron spins, and incompatibility principles through face-to-face communication at the conference. ”

“…… 1924 is the year of the Solvay Conference, and I would like to invite you to the Solvay Conference in October. However, some of the members of the committee have a strange attitude, and they take into account other factors besides academic standards and academic contributions......"

The Solvay Conference has a committee, of which Lorenz is the permanent chairman.

Chairman Lorenz was willing to invite Li Kangping to the Solvay Conference in 1924, but some members of the committee did not want Li Kangping to go to Brussels.

Since 1911, the Solvay Conference has been attended by all white people, and no physicists of color have ever been invited to the conference.

Some members "also take into account other factors", which should be related to skin color.

Face-to-face or letter-to-face, Mr. Li has dealt with many white physicists.

In general, the white physicists that Li Kangping came into contact with, their basic principles are academic principles, and they may refute Li Kangping academically, but they rarely treat Li Kangping unfairly in terms of nationality and race.

However, there have always been proud boys or men who hold the idea of white supremacy, and this thinking is so ingrained that it is difficult to change.

Meetings are more efficient and decision-making than letters, as evidenced by the APS Annual Meeting.

For Li Kangping, the Solvay Conference of 1924 was extremely important, and it could determine the future development of physics.

Li Kangping naturally wants to attend such an important international academic conference, and he hopes to unify his thoughts at the conference and work with physicists to lead physics into a new stage.

Specifically, Lorenz did not name any committee members who did not want Li Kangping to attend the Solvay meeting.

What is certain is that Lorenz is more than willing to invite Li Kangping to the Solvay meeting.

The list of members of the Solvay Conference Committee has long been made public, and the most famous member is Maurice de Broglie.

Maurice de Broglie is famous not because of how much he has contributed to physics, but because he is a French duke + German prince.

Broglie is a small town in the Normandy region of France, and lie means a person whose territory is in Broglie.

The de Broglie family is famous and powerful, and it has produced many prime ministers, prime ministers, foreign ministers, justice ministers, and ambassadors to the United Kingdom.

All men in the de Broglie family were German princes, but the title of Duke of France could only be inherited by the eldest son.

Maurice de Broglie is the eldest son, he is the Duke of France + Prince of Germany.

You are honestly a nobleman, why are you engaged in physics research?

Maurice de Broglie devoted himself to physics and guided his younger brother, Louis de Broglie, to study physics.

Li Kangping also did not know what Maurice de Brow's attitude was about factors other than academics.

All in all, to participate in the Solvay Conference, I still have to ask Lorenz.

Li Kangping replied to Lorenz, in which he expressed a strong desire to participate.

Let's say that the statistics of the American radio sales market in 1923 are out.

In 1923, 3.1 million radios were sold across the United States, with total sales totaling $136 million.

It took only three short years from the opening of Pittsburgh's first radio station in late 1920 to the end of 1923.

During these three years, radio sales grew at an astonishing rate.

Behind these radio sales figures lies a picture of postwar American life.

Huge radio stations are all over the United States, and the roofs of residential homes are covered with antennas.

Roxy and his buddies, Happy Boy, AP Gypsy, and Rudy Valli, chant and whisper over the old, small Florentine radio.

Graham McNemi's voice has become the most familiar voice in the American people, and his voice is constantly shouting in the living room of the American: "He did it!" Yes, ladies and gentlemen, he did! He touched the ground and scored! I want to tell you that it was a really good game......"

The popularity of radios is closely related to the U.S. economy and people's livelihood.

There is no doubt that as the post-war U.S. economy recovers, there is a high probability that radios will continue to sell well.

The Poseidon brand radios went on sale at the beginning of the month, and in 1923 dealers picked up 26,000 units and sold 22,000 units.

Compared with the overall sales market of 3 million units in the United States, the sales of Poseidon brand radios of less than 30,000 units are almost negligible.

According to the company's financial report, the number of pick-ups and terminal sales of Poseidon brand radios in 1923 brought a profit of $700,000 to the Poseidon Radio Company.

At present, in February 1924, the Poseidon Radio Company had a total of 1,500 employees, with a production capacity of 133,000 units per year in a single shift, and a maximum capacity of 400,000 units per year in three shifts.

"Hey, John, you can see that the U.S. radio market continues to improve, and our superheterodyne radios have just been produced and taken away by dealers. I told you last year that we should recruit 3,000 people, but why are there only 1,500 people now? Li Kangping said to General Manager John Sanders.

John Saunders explains, "There is a shortage of labor in Jersey City, and I'm looking at hiring workers from other New Jersey cities. ”

"John, I don't care which city you go to recruit workers, I ask you to recruit three thousand people in the shortest possible time! Promise me, you can do it. ”
