Nathan Rothschild soon discovered that in the fifth carriage there was not a single person with the surname Bonaparte. However, he did not feel that his money was in vain, because he knew that these people were closely related to the Bonapartes. Although they were not surnamed Bonaparte, they were the most central and important part of the behemoth of the Bonaparte family.

Most of these people are, or will be, the heroes of the times who are surrounded by the spirit of the plane, and it is definitely worth the fare he pays to get to know and get in touch with these people. However, after a brief conversation with them, Nathan Rothschild found that it did not seem particularly easy to get in touch with these people. Because, even when those guys are resting, he can't understand what comes out of their mouths.

Fortunately, he soon discovered a man who was also interested in economics, and who had the highest position in the carriage. This man was Lavoisier, honorary president of the French Academy of Sciences.

Mr. Lavoisier is fifty-nine years old this year, which is an advanced age in this era. As a scientist, Lavoisier has also reached the age of retirement.

Thanks to many legends and stories, as well as the influence of many habits of the old era, many people have an unrealistic fantasy about old scientists. Just like in a book that Joseph read in his previous life, there is such a saying:

"Gao Songnian, president of Sanlu University, is an old scientist.

The position of this "old" word is very difficult, it can describe science and can also describe scientists.

Unfortunately, scientists are not quite the same as science; Scientists are like wine, the older they get, the more valuable they are, while science is like women, they are worthless when they get old. In the future, the Chinese grammar will be fully developed, and one day it will be clear that "old scientists" and "old scientific homes", or "scientific homes" and "old scientists". It's still very early, so you might as well call it in general. ”

However, Mr. Qian, who wrote the book, still doesn't know much about the profession of scientists, natural science is different from literature and history, and there is no such thing as "scientists are like wine, the older they are, the more valuable they are". Science, on the other hand, is valuable as long as it is not disproved by falsification, whether it is old or new. For example, the laws of thermodynamics are hundreds of years old and are still awe-inspiring. But a scientist is really like a woman, who is worthless when she is old.

In the study of literature and history, the accumulation of experience and knowledge is more important, so scholars of literature and history are indeed a bit like wine. This is not the case with the natural sciences, which require too much of the brain's data processing capabilities. It requires the brain to work under high load for a long time. With the increase of age, the decline of various functions of the human body is also inevitable. Therefore, although the experience and insight that comes with aging is important, it is not enough to compensate for the harm caused by the decline in physiology. So most of the natural scientists, their most important achievements were made in the prime of life. And when they get old, they are basically just like some kind of statue.

Monsieur Lavoisier now also clearly feels the decline in his energy and thinking skills. His hands were shaking, and in the laboratory, he was not able to do experiments on his own. And after getting the experimental data, when analyzing it, it is often impossible to keep up with the assistants' ideas. This made Mr. Lavoisier sigh that it was really time for him to retire.

However, after intensive use, the brain's ability to process data has decreased, and even some inexplicable errors are often made, just like a graphics card used to mine. But Monsieur Lavoisier was not quite willing to go straight to symbolism.

Mr. Lavoisier has always had two hobbies, one in science and the other in money.

Now that science has clearly disliked him for his old age and decrepitude, after his body has been hollowed out, he is no longer willing to give him a good look; So he also had to shift more of his attention to another hobby. Lavoisier felt that his current data processing power did not seem to be enough to run a natural science app, but it should still be enough to run a business program.

Of course, considering only the data processing capacity, Lavoisier's judgment is not bad. What he didn't take into account, however, was that there was so little data in his database on how to buy and sell.

But the common hobby still made Lavoisier and Nathan Rothschild very talkative. And Rothschild also found that although Lavoisier was not really proficient in how to do business, he could sometimes come up with one or two pithy words that were particularly to the core, and even Rothschild had a feeling of being stunned. Then, after a brief conversation, Rothschild found that such words basically came from Joseph Bonaparte.

"Joseph Bonaparte was just a scientific monster, he was an all-round monster." Nathan Rothschild couldn't help but think.

He got into a relationship with Lavoisier, much to Nathan Rothschild's satisfaction. He felt that the money he had spent was too much worth it. He knew that Monsieur Lavoisier was close to the Bonaparte family, that Joseph Bonaparte's wife was Lavoisier's niece, and that through him he should have access to the real man at the helm of this large family.

By this time, most of the passengers had already boarded the train, and the train sounded its whistle, making a long "whine" sound, and then it vibrated slightly, and then looked out through the glass window, and you could see that everything outside began to slowly recede.

"Ah, the train is going. Well, in the end, it is still the passenger car that is more comfortable and much better than the freight train. Lavoisier said.

"Monsieur Lavoisier, you have also been on a freight train?" Nathan Rothschild asked.

"Sat at Lorraine Steel. I was curious to sit on a flatbed truck with a group of workers, and I caught a cold from the wind. Well, the freight train is much more bumpy than this, but if you don't take into account the wind, even a flatbed car is more comfortable than a horse-drawn car. ”

The two men were talking, and the speed of the train began to get faster and faster.

"Do you know how fast this train can go, Monsieur Lavoisier?" Nathan Rothschild asked.

"Ah, you're asking the right person." Lavoisier replied proudly, "The maximum speed can reach 70 kilometers per hour. However, considering the coal consumption, this is not the most economical speed, and the most economical speed is somewhat different depending on the load, but it is generally around 50 kilometers. ”

"So fast?" Nathan Rothschild pondered in his mind for a moment, and then said, "Monsieur Lavoisier, don't you think that the railroad will be a very profitable business?" ”
