night

Xiaoman holds the child to feed the milk powder, and now she can only be close to the child at this time every day, but I don't know why... The two little ones were far less excited to see their mother than they were when they met their father, and if it weren't for the fact that the bottle attracted the siblings, they might have cried by now.

“...”

"I'm very unhappy!" Yang Xiaoman hugged the child, looked at Xu Mang angrily, and said indignantly: "Why is the child not close to me? It's like a stranger, if it weren't for the bottle in his hand, he might be in trouble. ”

"Nonsense!"

"How much time have I paid?" Xu Mang said angrily: "I am almost always with my son and daughter, Xiao Man... There are some things that need to be touched with love, such as getting along with children, there is no way... Time is love!"

"Love, love, love... Love your size!" Yang Xiaoman said angrily: "And since you have a child, you don't seem to care about me so much, I'm your wife... Can you pay attention to your beautiful lady when you have time?"

"Beautiful fart!"

"You've become a woman, do you really think you're a beautiful girl in high school?" Xu Mang glanced at him and said indifferently: "Next year's Women's Day... I have a gift for you. ”

Yang Xiaoman was about to explode, and he really wanted to beat this guy to death with one punch... What is called having become a woman, and what gifts to prepare, I really don't know how to write the word dead... Glancing at it, he said angrily, "Shut up!"

Words fall,

Hurriedly asked, "How's the plan going?" There are still five days to go... Can you hurry up?"

“...”

"The day after tomorrow gives you a complete plan. Xu Mang held the tablet and said seriously: "Can you give me a little money?"

Yang Xiaoman frowned, and said with a curious face: "What do you want money for? Don't you have a lot of money? Why do you still ask me to take money? Speaking of which... What about your old salary, and the money you swindled in the United States?"

"Are you embarrassed to talk?"

"The last time I lent you short U.S. stocks, you haven't paid me back yet. Xu Mang said angrily: "I don't have any money on me now... The last time I bought a computer, I still asked Chen Xi to pay in advance, and when I went out to eat, someone else paid in advance. ”

“...”

"How much are you going to want?" Yang Xiaoman asked: "I remember that I gave you a card before, which can overdraft quite a lot of money, and it is impossible to spend it when you save some money, unless you mess around... And you're already a father, and there are some places that you don't go to... For example, what bars, nightclubs, clubs. ”

"Who do you think of me?" Xu Mang frowned and said seriously: "I'm a decent gentleman... I'm going to provoke the wildflowers outside? After all, the house flowers are so fragrant... Hey, hey, hey, don't you say?

After that,

Xu Mang began to move his hands and feet, not to mention... Since Xiaoman gave birth to a child, she has completely transformed into a woman, a cute and mature woman, of course... The premise is that today's Xiaoman has changed a little and has become a little larger.

If I had to describe it in one word, it would probably be love.

At this point,

Xu Mang glanced at his son and daughter, and said seriously: "Anyway, is the child full?

"Hey, hey, hey!"

"Are you ashamed?" Yang Xiaoman looked at her husband with a blushing face, and said angrily: "I thought there were two more children, but it turned out to be... I never thought that it was three children... The child is hungry, are you hungry too?"

The next second,

The atmosphere in the bedroom was a bit eerie, gradually becoming a little uncomfortable, filled with a hint of dog food.

Following

Xu Mang hugged Xu Yang and Xu Man, sisters and brothers, and started a pleasant day between father and son and father and daughter. He's going to take the two little ones to the institute to see how his dad works, and at the same time experience what it's like to be a scientist.

Feeding bottles, diapers, and strollers are being loaded into a nanny car, and this Alpha was borrowed from Chen Xi to pick up Xu Yang and Xu Man.

"Huh?"

"What are you doing here?" Yang Xiaoman frowned and said with a blank expression: "Where are you going to take the child?"

At this point,

Xiao Man saw Xu Mang walking out with the child, and stopped, "What are you going to do?"

"Huh?"

"Go to the research institute!" Xu Mang said with a natural expression: "This is a parent-child activity between me and the child, don't interfere with you, a person with a foreign surname... Hurry up and get to your class. ”

After that,

I got into the car with my children and left the villa.

"Hey!"

"Xu Mang!" Yang Xiaoman was so angry that he exploded, and roared angrily: "If you train Xu Yang and Xu Man to be the same people as you, the old lady will divorce you!"

...

Xu Yang Research Institute,

Huaguo's premier physics institute, although there are not many people... But in its world, it has made a lot of achievements, and the word Xu Yang comes from Xu Mang's son, who is pushing a stroller at the moment, and happily walks to the institute.

"See?"

"This is where Dad works, how about we study the atomic clock together later?" Xu Mang squatted down, teased his son and daughter, and said, "Of course... By the way, Dad taught you quantum physics and relativity. ”

"Ugh..."

"Dad knows that when you are in your mother's womb, you must have been devastated, but in fact, you don't want to be an artist at all, you want to be a scientist. Xu Mang sighed and said helplessly: "But there is no way, this tigress in our family is not an ordinary fierce." ”

"Xu Yang!"

"Xu Man!"

"Today we will temporarily reach a united front against that tigress, and if we agree, do not squeak. Xu Mang said seriously.

Sure enough,

The son and daughter looked at their father with wide eyes and confused faces.

"Good!"

"The Avengers' Alliance of Justice officially launched today. Xu Mang approached his son and daughter, rubbed the little guy's little face affectionately, and said, "But... In case something happens, the two of you have to help Dad with thunder, and Mom won't do anything to you anyway. ”

Xu Yang:(°ー°〃)

Xu Man: (°ー°〃)

Father

What is he talking about?

afterwards

Xu Mang turned on the computer, and the child was holding a milk bottle, happily...

"Listen carefully!"

"Next, Dad will explain the concept of atomic clocks. Xu Mang turned around and said to the child seriously: "I don't understand... Beware of Daddy spanking your ass. ”

"According to the basic principles of atomic physics, atoms absorb or release electromagnetic energy according to the energy difference in the order of different electrons, that is, the energy difference of the different electron layers around the nucleus. ”

"Attention!"

"The electromagnetic energy here is discontinuous!" Xu Mang glanced at Xu Yang and said angrily: "Xu Yang... Don't talk about it for the time being, look at your sister, how seriously you listen, just you've been spitting the bottle. ”

Followed by

Xu Mang finished talking about the concept of atomic clocks, and then talked about the origin of atoms.

"According to Einstein's theory of relativity, in which time dilation catches the eye, at higher altitudes, time passes faster, but when you go faster, time passes more slowly. "So the only way to accurately measure time is to control the clock by the tiny vibrations of the atoms themselves," Xu said. ”

"Xu Man!"

"Answer the concept of length contraction in the theory of relativity about time dilation. Xu Mang asked.

"Babble... Oh... Ahh

Although he didn't know what to say, Xu Mang still nodded, showed a smile, and said, "Very good, your mother is much smarter!"

"Oops!"

"Xu Yang!"

"Look at my sister... Look at you again, go home and see if I don't beat your ass!" Xu Mang looked at his son, and at this moment he felt that his son was so naughty that he didn't want it compared to his daughter.

afterwards

Xu Mang put away his playfulness and began to design a new ion trap design for the quantum clock, reducing the thermally induced ion motion, making the operation closer to the ideal ground state, or the lowest motion energy level, and then choosing a suitable frequency.

Because the ion trap is operated at a lower frequency, unnecessary ion movement caused by the electric field used for the ion trap is reduced.

And that's just the beginning.

There is also improved quantum control that reduces the uncertainty of frequency shift measurements caused by ion motion.

midday

Xu Mang, who had been busy all morning, stretched his waist and found that the children had already slept, so he couldn't help but take out two bananas, and went out too quickly... I forgot to bring lunch, just some fruit.

No way...

Let's eat it.

suddenly

The door of the office was opened, and Yang Xiaoman walked in with a takeout and a black face.

"Hungry, right?" Yang Xiaoman glanced at Xu Mang, and said angrily: "I didn't bring food when I went out in the morning, so I left in a hurry... Big idiot!"

"Hey, hey!"

"Wife, you're so nice. Xu Mang smiled and said, "Oh, it's braised pork?"

“...”

"Is the baby making trouble?" Yang Xiaoman said seriously while taking out the vegetables and rice from the bag: "In an unfamiliar environment." ”

"Nope. ”

"I also taught my children about the concept of time dilation in the theory of relativity, as well as the concept of ion traps. Xu Mang smiled: "Listen carefully!"

Yang Xiaoman: (# ̄~ ̄#)

At this moment,

A song appeared in Xiao Man's mind... Kids, do you have a lot of question marks?

After lunch,

Xiao Man originally planned to tease the children for a while, but seeing that he slept so soundly, he couldn't bear to disturb their dreams, so he could only quietly leave the research institute.

subsequently

Xu Mang began his work, but the work was at a stalemate, and progress on the new ion trap design was a little slow.

"What should I do?" Xu Mang sighed, staring at the computer boredly, and was a little stunned for a while.

"Babble... Woohoo... Ahh

Daughter Xu Man woke up and kept talking to Xu Mang.

"Yo Yo Yo..."

"Is Dad's little padded jacket awake?" Xu Mang happily hugged the child into his arms, kept teasing her, and said, "Do you miss Dad?"

In the face of Xu Mang's inquiry,

Xu Man kept talking about his words, as if he wanted to express something, maybe it was his love for his father.

syllable

A crisp sound,

Xu Man's noisy little foot kicked the keyboard, instantly making her cry.

"Don't cry, don't cry!" Xu Mang was also anxious, slapped the keyboard hard, and said: "Dad has already helped you call back, we don't cry or cry..."

Then

When Xu Man stopped crying, Xu Mang saw an amazing scene, a web page popped up in front of the screen, and the content of this web page turned out to be... A paper on ion traps.

Just by reading the summary, Xu Mang suddenly realized.

That's right!

Isn't that enough?

"Xu Man!"

"You're really Dad's intimate little padded jacket!" Xu Mang affectionately rubbed his daughter's little face with his face, and said excitedly: "You kick... It directly solved a puzzle in Dad's heart!"

Xu Man: ???
