At the Yale Alumni Association Mike? Accompanied by Mr. Donaldson, Sun Yuanqi arrived at the New York train station in mid-May.

In the crowd of greetings, in addition to acquaintances from Yale, MIT, the American Chemical Society, and a bunch of reporters, Sun Yuanqi also saw another familiar face: Mr. Bergman. Mr. Bergman's expression was very serious, and he felt that there was something very important to say to himself.

"Could it be that something is wrong with the production of MSG? Can't! There are countless precedents for success. Sun Yuanqi thought in his heart. When he had finished dealing with the reporters and said "no company" to a few acquaintances, he came to Mr. Bergman and said hello.

Mr. Bergman nodded, shook hands and said, "Now there is a very important matter, about you, I want to talk to you, I hope you can take it seriously, and take the time to solve it as soon as possible!" ”

Sun Yuanqi was stunned: "What, is there a problem with the patent right of monosodium glutamate, or is there something wrong with the production process?" ”

"No, it's neither, the patent has already been applied for, and the pre-production preparations are going well. I'm not talking about this, it's about Lilith. Mr. Bergman's expression was a little tangled, and he took Sun Yuanqi to a secluded corner before he said solemnly: "Lilith, she's pregnant!" ”

"Pregnant?" Sun Yuanqi was stunned, and his head didn't react for a few seconds, as if it was blank, as if he didn't know how to deal with this news. After a moment's hesitation, he asked in a tentative tone, "Mine?" ”

Mr. Bergman saw Sun Yuanqi's puzzled expression, and had to wipe his face to continue to explain, and his tone was no longer so gentle, and even a little angry: "Yes, yes, that's right, it's yours." Lilith didn't understand anything, she had no idea what pregnancy was all about. In the early stages of pregnancy, she also did not have any reaction. Until a month ago, my wife found out that Lilith's body was abnormal, and she thought she was sick, but she asked the doctor for a check-up and found out that she was actually five months pregnant! …… God, this has never happened in our family! ”

Sun Yuanqi was already stupid, this kind of thing can't be solved with a word of "Sorry", and he muttered unconsciously: "Yes, God, how could this happen!" ”

Mr. Bergman was a lawyer after all, and he knew the news a month earlier, so he quickly regained his composure: "Yank, now is not the time to complain. Although Lilith is very at fault in this matter, as a man, you can't shirk responsibility, can you? And, now that Lilith is six months pregnant, we should fix the problem as soon as possible instead of regretting it here! ”

"Yes, I'll take care of it." Sun Yuanqi also regained his composure at this time, "In our Qing country, allowing the existence of polygamy is not a problem for me. The point is that you ......"

"We?" Mr. Bergman nodded, "Yes, we are devout Jews. Although polygamy was practiced in Judaism in the early days, polygamy was explicitly forbidden in our church after the rabbinic council at Worms in the early 11th century. ”

Sun Yuanqi was stunned again: Ah, Mr. Bergman's family is actually Jews?

Mr. Bergman's voice changed: "What is your religion?" ”

"There is no ...... faith"

"That's fine." Mr. Bergman breathed a sigh of relief, "In the United States today, 98 percent of Jews are interchurch, after all, another 2 percent are interchurch. Extra-religious marriages are generally Christian Protestants, Catholics, and non-religious believers. Before you came, we had already figured out a way, that is, you apply for a nationality in the United States - you don't have to worry - I have checked the relevant information, you China does not have the corresponding nationality laws and regulations, and we in the United States allow dual citizenship. If you apply for U.S. citizenship, I'm sure many people will contribute to this, and USCIS will be happy to see it. And then you used this nationality to marry Lilith, which is kind of barely bypassing the canon. ”

Historically, China's first written nationality law was the promulgation of the "Great Qing Nationality Regulations" in the first year of Xuantong (1909), which stipulated: "Before the implementation of these Regulations, if a Chinese person has lived abroad for a long time due to birth, if he still wishes to belong to Chinese nationality, he shall be deemed to still be of Chinese nationality." "It's kind of a reluctant recognition of dual citizenship. But in 1902, it was still a blank slate.

Since Mr. Bergman, as a lawyer, thinks it is feasible, what else can Sun Yuanqi have in question?

The original plan was to be invited to give a few lectures on "wave-particle duality of light" and "quantum mechanics" in New York, and take a week off by the way. Then he went to Yale University in New Haven to guide his colleagues in the Elemental Laboratory with isotope theory and decay theory, and re-analyzed uranium ore carefully in order to discover element 91 protactin; After that, we went to MIT in Boston to see Vera's parents. Because of this sudden change, Sun Yuanqi's itinerary was also forced to change. After two days in New York, where I made a presentation, I hurried to Boston.

Mr. Bergman was the only one who greeted Sun Yuanqi at the train station. Sun Yuanqi didn't even inform MIT in advance, only saying that he had some personal matters, and the time arrangement might be more flexible, and he would inform him in advance when he would arrive at school.

When I got out of the station, there was already a carriage waiting there. Hopping into the carriage, both remained silent. The carriage turned around the street and drove out of the city. Mr. Bergman saw Sun Yuanqi's doubts and explained in a low voice: "Because Lilith's posture is very obvious, in order to avoid unnecessary trouble, at the end of last month, she moved to a villa in the suburbs. ”

Sun Yuan nodded from the beginning, indicating that he understood, and could only say guiltily: "I'm sorry!"

Perhaps they had known that Sun Yuanqi was coming, but Sun Yuanqi and Mr. Bergman had just gotten out of the carriage and had not yet pushed open the courtyard door when they saw Mrs. Bergman helping Lilith out, and behind them were several of Lilith's brothers.

Seeing Sun Yuanqi, Lilith returned to her girlish habits, threw off her hand and wanted to run over, but as soon as she stepped on her legs, she felt inconvenient to her body, a little annoyed, and a little happy, she looked at Sun Yuanqi with annoyance, and her eyes seemed to say: "Look, it's all your fault!" "A coquettish look.

Sun Yuanqi immediately threw away his luggage, walked forward quickly, gave Lilith a big hug, and whispered softly in her ear, "Honey, I'm sorry." ”

"Nope! These are all voluntary and I want. Whoever says 'I'm sorry' should be saying that I'm causing you trouble! Lilith pushed Sun Yuanqi away, her beautiful blue eyes covered with tears, "Actually, I am very, very happy to learn that I am pregnant." Today, as long as you can come and take a look, I am very satisfied. ”

When Sun Yuanqi heard this, his heart was full of emotion and sweetness, and he rubbed Lilith's upturned little nose with his fingers, and whispered: "Silly girl!" Only then did she realize that the playfulness and liveliness between Lilith's eyebrows had faded a little, adding to the laziness and softness of the young woman.

Mr. Bergman, who is a "Jew" + "lawyer", deserves to be the elite of the elite. On the evening of the same day, after bringing a large number of documents for Sun Yuanqi to sign, on the premise of not delaying the preparation of the "Bergman (USA) Condiment Co., Ltd.", just one week later, he sent the completed American citizenship certificate and marriage certificate to Sun Yuanqi, who was staying in the MIT laboratory, and kept complaining: "It could have been faster, but they are all those old-fashioned bureaucrats, and they know that they are wasting precious time!" ”

A few days later, a brief but formal wedding took place in Mr. Bergman's villa on the outskirts of the city. Although Lilith wore a fluffy wedding dress, her bloated belly could still be vaguely revealed. As the saying goes, "Don't make a family ugly." "Only a few of the closest friends and relatives are invited to the wedding.

This is also the first time that Sun Yuanqi has participated in a Jewish wedding, and he still participates in it as the protagonist.

The marriage ceremony takes place under a canopy, which is made up of four pillars and a canopy. The marriage ceremony under the canopy was simplified to a very short time. BEGINNING WITH A WINE TASTING BLESSING CEREMONY CALLED BIRKATERUSIM, THE PRIEST RECITES A BLESSING AND THE BRIDE AND GROOM DRINK THE FIRST GLASS OF BLESSING WINE. THIS IS FOLLOWED BY A SHORT DEDICATION CEREMONY CALLED BARAY, AFTER WHICH THE GROOM PUTS ON A WEDDING RING FOR THE BRIDE. THE RABBIS THEN READ THE KEIUBAH BLESSING, THE GROOM EXPRESSES HIS HEART TO THE BRIDE, AND THE TWO BEGIN TO PRAY FOR THE BLESSING. AFTER THAT, THE PRIEST SINGS SEVEN WEDDING HYMNS TO EXPRESS THE SEVEN BLESSINGS, AND THE COUPLE DRINKS A SECOND CUP OF BLESSING WINE. Finally, a glass glass is broken, which marks the end of the wedding ceremony. The bride and groom leave the venue in the same way, followed by the bride and groom's parents, bride-in-waitress, rabbin, and grandparents. AFTER THAT, THE BRIDE AND GROOM ARE BROUGHT INTO A ROOM CALLED YICHUD, AND THE TWO STAY ALONE FOR ABOUT 10 TO 15 MINUTES, WHICH IS EQUIVALENT TO ENTERING A CAVE ROOM.

Compared to the hustle and bustle of Chinese weddings, this wedding is much quieter. Lilith's two older brothers and one younger brother did not ask for favors, but were courteous and actively involved in the ceremony as gentlemen.

After the wedding, Sun Yuanqi's life became more and more busy:

The component research of the MIT Electronics Laboratory has entered a critical period, and various circuit characteristics can basically achieve the original concept, and the signal modulation circuit is currently being built. However, the construction of the line is definitely not an overnight thing, even if there is already a schematic diagram, but the line made out does not achieve the expected effect at all, it is very likely that a capacitor is added in front, and the gain of the entire circuit will be completely changed; This capacitance can be subtracted, and the circuit in front is unstable. In short, it's very troublesome, and it tests people's patience very much.

Colleagues at Yale's Elements Lab didn't have it easy, either, and although protactinium is a naturally occurring radioactive element, it does not exist in nature and is mainly found in the fission products of uranium, thorium and plutonium. In the laboratory, it is mainly found in the decay of uranium. However, the dangerous radioactivity aside, because radium has great practical value in the treatment of tumors, the price of one gram of radium at that time was 100,000 US dollars, far exceeding the price of gold. Colleagues often look for new elements in less than 1 microgram of decay. Protactinium-231 is the most stable isotope of protactinium, with a half-life of 32,760 years; Moreover, the half-life of protactinium-234 is only 6.7 hours, and looking for it is tantamount to a race against time.

He is also actively working on the topic of "radioactive decay mode" with Professors Rutherford and Martin. Of the more than 2,000 nuclides found, the vast majority are unstable, and they spontaneously metamorphose into another nuclide while emitting various rays, a phenomenon known as radioactive decay. As far as we can see now, there are four main common patterns:

α decay (release of helium nuclei with two positive charges);

β decay (including β-decay that emits electrons while simultaneously emitting antineutrinos; emits positrons and at the same time emits neutrinos β+ decay; and electron capture EC, in which the nucleus captures an electron outside the nucleus);

γ decay (including γ transitions that emit electromagnetic radiation of very short wavelengths (often less than 0.01 nm); the nucleus gives excitation energy directly to the electrons outside the nucleus, causing the electrons to leave the internal conversion IC of the atom);

Spontaneous fission SF (spontaneous fission of an atomic nucleus into two or more nuclei of similar mass).

In addition, there are several rare decay modes, such as P radioactivity (emitting protons), carbon-14 radioactivity (emitting carbon-14 nuclei), β delayed P emission (β decay and then releasing protons), β delayed N emission (β decay and then emitting neutrons), binary β decay (simultaneous release of two electrons and two antineutrinos), etc. Sun Yuanqi knew that with just a few people and such equipment, it was estimated that he could find and summarize more than two, even if he was lucky.

In the middle, I also had to take time to go to the O&C office and coordinate with them on the revision of the university plan. Although I don't have a solid foundation in campus planning, as a person with many years of experience in college life in later generations, I have never eaten pork, but I have seen countless live piglets. In Sun's view, the university campus designed by the firm is a bit old, which will eventually limit the development of the school. So I communicated with the designers of the office about what I saw and thought, hoping to further revise the campus plan so that it could not only adapt to China's national conditions, but also present my own ideas.

With such a back and forth, there is little time for Lilith. As for Vera's parents, perhaps because of the guilt of remarrying Lilith, they never had the courage to visit. However, the more I delayed, the more I didn't dare to go. Sun Yuanqi knew that this hurdle would eventually be overcome. After much deliberation, one Sunday afternoon, following the mailing address, came to Mr. Coster's house.

It is said that this is the first time Sun Yuanqi has been to Vera's house, and he is guilty, and he dares to ring the doorbell when he is in a trance.

"Come on, come on, please wait a minute." A woman's crisp voice came from inside the room.

Sun Yuanqi was thrilled when he heard this, and thought in his heart: "I heard Vera say that she only has an older brother who is two years older, and she hasn't heard of sisters?" Did you ring the wrong doorbell? Just as he was about to turn around to check the address, someone had already opened the door, and it was a young woman.

"Excuse me, is this Mr. Coster's house?" Sun Yuanqi asked tentatively.

"Yes." The girl nodded, her eyes looking up and down at the black-haired and black-eyed young man outside the door, "You are...... ...... from China The scientist? ”

Looking at her demeanor, it seems that she has heard of herself. Sun Yuanqi introduced himself: "Yes, I am Vera's husband, you can call me 'Yanke'." Is Mr. Coster at home? ”

"At home, at home, please come in." When the girl heard this, she immediately opened the door and invited Sun Yuanqi into the house.

At this time, Mrs. Coster, who heard the movement, also came to the door, and when she saw Sun Yuanqi, she greeted her excitedly: "Ah, isn't this Little Yanke?" Come inside, my dear. ”

After the hug, Mrs. Coster complained: "We read the newspaper a few days ago, and it said that you were in the United States, and we were worried that you would not be able to find it." If it weren't for something, we'd all go to MIT to ask for your news! ”

Sun Yuanqi said sneeringly: "I also have some things to delay, and I have delayed ......."

As she spoke, the girl had already informed everyone else in the room. It turned out that the people in the house were having a meeting upstairs, and only the little girl making coffee was downstairs, and when she heard the doorbell, she opened the door first.

Mr. Coster, who has always been serious, also showed a smile when he saw that it was Sun Yuan who got up. After saying hello, there was already a young man who was six or seven points like Vera, and stepped forward to give Sun Yuan a strong bear hug: "Haha, you shouldn't know me, right?" I'm Vera's brother, you can call me Jamie. I know you, your name is Yank, isn't it? ”

Sun Yuanqi smiled and nodded, "Yes, I'm Yanke!" Jimmy, it's a pleasure to meet you. ”

"Come on, come on, I'll introduce you to my friends." Jamie looked very excited, patted Sun Yuanqi on the shoulder, and said loudly to the group of young men behind Mr. Coster, "Dear gentlemen and ladies, let me introduce you to a guest. Coming from the distant and mysterious East, he graduated from a prestigious university in the United States, and his research results are remarkable all over the world. He was a handsome young man, he was a professor at several universities, he was a famous scientist who fought to the death against Sir Newton, and most importantly, he was the brother-in-law of the famous design master Jamie. He, our dearest Yank? Dr. Johnson! Let us welcome him with the warmest applause! ”
