After a bit of laughter, everyone sat down in the living room, and the girl served the brewed coffee. At this time, Sun Yuanqi learned that she was Jamie's girlfriend, and he had heard Jimmy talk about himself, so he knew a little about his identity.

Sun Yuanqi took a sip of coffee and said apologetically: "I'm really sorry, I hope my presumptuous arrival didn't disturb you!" ”

"Not at all." Mr. Coster said firmly, "Leave them alone, they are just fooling around." ”

Jamie, who was sitting on Sun Yuan's side, shrugged, and then patted Sun Yuanqi on the shoulder: "I said dear Yanke, as a model of daring to challenge authority, you should perhaps teach our esteemed Mr. Principal a lesson, so that he can realize that the premise of making a great career is to have the courage to break the rules, not to look ahead!" ”

Sun Yuanqi laughed secretly in his heart: I didn't expect that the serious Mr. Coster actually had such a rebellious son. Oh, and a rebellious daughter, now in the far East.

Mr. Coster was visibly annoyed, and put down his coffee cup heavily: "You're not brave enough to break the rules, you're messing around!" ”

Jamie spread his hands: "According to the newspapers, when Yanke proposed that light has wave-particle duality, those orthodox scientists also said it was nonsense. The result? ”

"Humph!" With Yank by his side, Mr. Coster could not refute anything, so he had to express his disdain with this attitude.

As soon as he came, he was used as a shield by his eldest brother, which made his father-in-law unhappy. This disaster of pond fish made Sun Yuanqi feel very depressed. Just as he was about to whisper what was the matter with Jamie, he heard Mrs. Coster advise, "Don't be angry, dear. Jamie, you don't have to say a word, he's your father, you have to respect him, you know? …… I'm sorry, Yank, I just came here to show you the joke. Alas, Jamie and his friends designed a new bike and wanted to build their own factory. However, his father was not at all optimistic about his design and plans. So—"

Sun Yuan nodded from the beginning, indicating that he understood. I was shocked again: in China at the end of the Qing Dynasty, there was no trace of bicycles at all. Even in the United States, I only see it a few times in a while. In this era, bicycles are a luxury, very simple, the manufacture of bicycles involves two major industries, steel and rubber, and the cost is very high. Again, such a factory is definitely not something that can be built by a group of people casually.

"Building a factory, that requires a lot of investment, right?" Sun Yuanqi asked tentatively.

"yes, who's to say it's not?" With a son on one side and a husband on the other, Mrs. Coster is also in a dilemma, "Jamie wants to use the family's savings, plus his friend's money, and borrow a large sum of money from the bank. And his father thought it was too risky, so he didn't agree with him to use it. In recent times, the two have been arguing over this issue. What a ......."

"What's at stake? It's just that Mr. Principal is worrying about the sky! Jamie was indignant, "I'll tell you, Yanke, that bike was designed by a few of us, and after preliminary market research, most of them thought it was great and were willing to buy it." That said, it has a great market prospect and there is no risk. Really, Yank, if you see the drawings, you will definitely approve of my idea! ”

"Or ...... Let Yank see? Mrs. Coster was choked by this dispute, and only hoped for an early end, and secretly decided in her heart that as long as her son-in-law was on whichever side she was on, she would be on whichever side the family was on, so that the atmosphere of the family could return to normal, "After all, Yank is a very famous scientist, and his insights must be very informative!" ”

Mr. Coster did not speak, and picked up the coffee on the table. With this gesture, he acquiesced to his wife's proposal.

"Great idea!" Jamie high-fived and shouted, "Linda, go to the study and get our blueprints!" ”

Linda, is his girlfriend's name.

Sun Yuanqi sighed secretly: What is this called? I study physics alone, and I don't have a boundary with industrial design at all, what good insights can I have!

After thinking about it, Linda had already taken the design drawings. Fortunately, in addition to the design drawings indicating various data, there is also a rendering. Obviously, the painter was very professional, and the renderings were like sketches, realistically drawing what the new bike would look like.

For a long time after the reform and opening up, bicycles have always been the preferred means of transportation for Chinese people, playing an important role in daily life, and used to be the most important part of the dowry. Moreover, the number of bicycles in China has always been the first in the world, and it even has the reputation of "bicycle kingdom". In Sun Yuanqi's memories: when I went to kindergarten and elementary school, my parents picked me up by bicycle; When I went to middle school, I rode my bicycle to and from school; When I went to college, I picked up my girlfriend from class on my bicycle...... It can be said that the bicycle grew up with Sun Yuanqi. In the past 20 years of life, I have ridden all kinds of bicycles, and my understanding of bicycles is also deeply rooted in the bone marrow. If there is a small problem with the bicycle, you don't need to find a repairer, you can do it yourself.

But looking at this rendering in my hand, how do I look at it and feel awkward: there is no support, no basket, no back seat, the frame is very awkward, the shape of the handlebar is very strange, and the saddle should be very awkward to sit up......

Facing the hopeful eyes of Jamie and Linda, the words that were too direct were really unspeakable, so I had to change the way: "Does the design of your bicycle meet the requirements of mechanics and ergonomics?" ”

Jamie was stunned: "Mechanics? Human, anthropological? What's that? What's the use? ”

"Let's start with mechanics. For example, through experiments, the saddle and bracket can be adjusted to make the rider's weight reasonably distributed to the front and rear wheels to reduce friction during travel; Design the texture on the outer tire to increase the friction coefficient and facilitate the uphill and downhill slopes; Adjust the pedals, flywheels, chains, wheels so that the bike travels the same distance with the least amount of force, or with the same amount of force, the bike travels farther. Sun Yuanqi paused, "Let's talk about human body." It is necessary to investigate the average height, weight, arm length, palm size, and even hip size of men and women in the bicycle consumer group, so as to adjust the shape of the saddle, the distance between the saddle and the bracket, the saddle and the pedal, etc., so as to make the bicycle ride more comfortable. Have you taken all of this into account? ”

Jamie and his friends opened their mouths wide and, apparently, they didn't think about it that much.

After a while, Jamie argued: "Actually, we don't have to think about it that complicated, because as far as I know, other bike manufacturers don't notice it." Compared to their bikes, ours is more beautiful and more marketable! That's enough. ”

"Oh." Sun Yuanqi was noncommittal, and then pointed to the drawings and said, "I think that in fact, this car can add a rear seat in front of it, which can carry one more person; A basket can be added in front of the handlebar to facilitate some items; A support can be added here for the rear axle to facilitate bicycle parking; A cover tile can be added to the flywheel to protect the chain; A lock can be added to the frame position near the rear wheel to prevent theft; You can add a brake here, and you can ...... here."

A group of young men who were originally full of confidence in the new car, with Sun Yuanqi's finger on the drawing, gradually their new car was useless. In addition to being frustrated, I can't help but be a little lucky: if the new bicycle he described appears on the market after it is really put into production, he will definitely lose all his money, right?

The atmosphere in the living room was a bit dreary.

Sun Yuanqi, who swept the face of his eldest brother as soon as he came, felt a little embarrassed, so he had to turn around and persuade: "Jamie, in fact, your design is already very good, yes, very beautiful!" ”

"No!" Jamie clutched his head in frustration.

Mr. Coster stroked his beard and looked at Jamie with some smugness: "Young man, didn't you just ask Yank to teach me how to have courage?" Now, shouldn't you let Yankejiao teach you? So that you have the courage to face setbacks and failures. ”

Beneath the serious surface of this principal gentleman, there is a lively heart.

"No!" Jamie shrank into the couch.

"I'm sorry, Jamie." Sun Yuanqi saw Jamie's appearance, and became more and more guilty, "I am studying physics, and I am not familiar with industrial design, so what I said may not be correct." You don't have to be upset. ”

"No!" Jamie stood up suddenly, "I think you're absolutely right, yes, when we designed it, we only focused on the existing model and beautifying it, and we thought it was the best bike." Now it seems that we were very wrong! We should go one step further in our design, like Yankee you, and have the courage to break all the current conventions and create a completely new model! ”

This guy can't go crazy because he hit too hard, right?

"I'm going to build bikes, yes, I'm hungry more than ever!" Jamie turned around and grabbed Sun Yuanqi's hand firmly: "Dear Yanke, you have to write everything you just said, no, draw it." Let's work together to build the perfect bike! ”

In this way, Jamie asked a friend named "Bieber" to come to Sun Yuanqi's office every night and draw the various parts of the new bicycle according to Sun Yuanqi's description. In order to make Sun Yuanqi more able to express his ideas, Jemmet specially instructed Bieber: As long as it is drawn according to Sun Yuanqi's meaning, don't argue, don't make assumptions.

Because of his apologies for Vera, or moved by Jamie's persistence, Sun Yuanqi spent several weeks of nights doing this, meticulously describing to Bieber: men's bicycle, women's bicycle; regular bicycles, mountain bikes; Tires, pedals, brakes, chains, saddles, supports, multi-stage flywheels...... In the end, even the appearance of rickshaws, scooters, and skateboards, as well as the gameplay of scooters and skateboards, were told to Bieber.

After Bieber finished the drawings, he asked Sun Yuan to look at them and modify them to be no different from the objects in his impression, and the work was finally over.

In this chaotic work and life, there are also things that make Sun Yuan happy.

One day at the end of May, Mr. Zhang Yuanji sent him a letter from Beijing, in which he gave him a general description of the school's progress, such as the recruitment of new teachers, and the list of teachers in charge of psychology, philosophy, and ethics, whose name was very familiar, was Wang Guowei. Sun Yuanqi was stunned: It seems that there is a very good master of Chinese culture in history who is also called Wang Guowei, these two people should have the same name by coincidence! Otherwise, how could he go and teach a course like psychology? Teaching history and literature is the right thing.

I didn't care about him at the moment, because Zhang Yuanji's letter also attached an English letter, which was said to be a physics teacher in the school, and he couldn't make up his mind, so he attached it with the letter and asked Sun Yuanqi to make a decision.

"Physics teacher?" Sun Yuanqi was happy in his heart, "Don't you know that I am the best physics teacher on the earth now?" But when he saw the first line of the cover letter, his jaw was about to drop to the ground. Because he saw a name: Albert Einstein.

It is said that between 1900 and 1902, the later physicist Albert Einstein was not ordinary and miserable: he thought that he could stay in school to teach, but his teacher did not take a fancy to him; Looking for a job, but there is no suitable oneself; wanted to marry his girlfriend Mileva, but his parents thought Mileva was a cripple, and for this, they even cut off his financial resources. In desperation, he even relied on being a tutor to make a living. It was not until June 16, 1902, on the recommendation of his friend Grossmann, that he was hired by the Bern Patent Office in Switzerland, and his life settled down.

This letter was written by Albert Einstein when he was in a hurry to go to the doctor, and he first introduced himself, where he was from, what year he was born, which school he graduated from, etc.; Then he mentioned Sun Yuanqi's paper "On the Electrodynamics of Moving Bodies and the Relationship between Mass and Energy", saying that this paper solved the problem that had plagued him for a long time; Finally, he expressed his interest in physics research and hoped to teach at the university, and followed a paper he published in the Leipzig Journal of Physics in 1901: "Inferences from the Capillary Phenomenon".

After reading the letter, Sun Yuanqi hurriedly flipped through the postmark, the letter was sent from Germany in April 1902, arrived in China at the end of April, and then crossed the ocean to the United States. It's been two months, and I don't know if this famous flower has anyone else's home?

Sun Yuanqi put down everything, ran to the telegraph office in a hurry, and sent a long letter to Einstein with a transoceanic telegram at all costs, saying that the professorship was vacant, and the bonus and benefits were preferential, especially mentioning that there are big problems in the current theory of relativity, such as the inertial frame cannot be defined, and the law of gravitation cannot be written into the framework of the relativity system, and I hope he can come to study this problem with him.

I don't know which condition tickled Einstein's itch, but he quickly sent a telegram saying that he accepted the offer. Sun Yuanqi was overjoyed, and hurriedly took out 5,000 US dollars from his salary and remitted it to Switzerland, hoping that Einstein would go to China at the right time.

A few days later, Sun Yuanqi returned from a business trip to Yale, and Jamie came to the door excitedly: "Yanke, a few of us have decided to open a factory to produce the kind of skateboards and scooters you designed!" ”

"You don't build bicycles, do you?" Sun Yuanqi was a little stunned.

"Of course you have to build it!" Jamie replied categorically, "That's our favorite!" However, the investment in the research and production of bicycles was too large, and we did not have the ability to do so for the time being, and we did not want to ask for money from Mr. Chancellor or the banker, so we decided to build simple skateboards and scooters first. ”

At least around 1900, the original scooters were already handmade in industrialized cities. A common handmade scooter is made of wood, with 75-100 mm wheels and steel ball bearings attached to the wheels of skates under one board, and then fitted with handles, relying on a tilting body or a rudimentary pivot connected by a second board. Another "advantage" of this structure is that it is very noisy, like a "real" car. Another structure is to divide a metal skate into two parts, front and back, connected by a wooden beam in the middle.

The scooter that Sun Yuanqi handed over to Bieber is a new generation product, which is more flexible, lighter and much quieter.

"We built a scooter in the first half of the month, and it's very cool!" Jamie was very excited, "You don't know, the youth of the whole neighborhood are attracted to him!" Believe that skateboarding is no less magical than it. So, their market prospects are very broad. We're going to do that in the future, while producing these two little things, we're going to redesign the bike the way you said. - As soon as the conditions allow, we will build a bicycle immediately! ”

"That's good." Sun Yuanqi is normal Jamie's plan.

"By the way, we have carefully kept the drawings you handed over to Bieber, and in the next few months, we will patent the most innovative parts of it. You don't have to worry, we have already agreed that 15% of the profit of the product will be used as your royalty. When the company is established, the contract will be sent to you. Jimmy patted Sun Yuanqi on the shoulder very righteously.

Sun Yuanqi didn't say anything, and immediately told Jamie some precautions about skateboards and scooters, such as the steering mechanism should be sensitive; The wheels can't be too slippery; The board should not be too bulky and should be elastic. At present, the price of aluminum alloy is higher than that of gold, and new materials such as carbon fiber have not been studied, so it is best to use five, seven or nine layers of maple boards.

Jamie wrote them down one by one, and as for how to finalize and produce them in the future, it depends on this group of young men.
