I really don't want to lie down and win

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

"listen carefully!"

"Next, Dad will explain the concept of atomic clocks." Xu Mang turned his head and said to the child seriously, "I don't understand... Be careful when Dad spanks you."

"According to the basic principles of atomic physics, an atom absorbs or releases electromagnetic energy according to the energy difference of different electronic arrangements, that is, the energy difference of different electron layers around the nucleus."

"Notice!"

"The electromagnetic energy here is discontinuous!" Xu Mang glanced at Xu Yang, and said angrily, "Xu Yang...stop sucking for now, look at my sister, how seriously you listen, you're the only one who's been sucking the bottle all the time." .”

Then,

Xu Mang finished explaining the concept of atomic clocks, and then explained the origin of atoms.

"According to Einstein's theory of relativity, in which time dilation is noticed, at higher altitudes, time passes faster, but when you go faster, time passes slower." Xu Mang said: "So The only way to accurately tell time is to control the clock by the tiny vibrations of the atoms themselves."

"Xu Man!"

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

"Yeah... ah... ah..."

Although he didn't know what to say, Xu Mang nodded, smiled, and said, "Very well, your mother is much smarter!"

"Hey hey!"

"Xu Yang!"

"Look at my sister... and look at you, go home and see if I don't spank your ass!" Xu Mang looked at his son. At this moment, he felt that his son was so skinny compared to his daughter.

after that,

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

Because a lower frequency is used to operate the ion trap, unwanted ion motion induced by the electric field for the ion trap can be reduced.

This is just the beginning,

There is also improved quantum control to reduce the measurement uncertainty of the frequency shift caused by ion motion.

noon,

Xu Mang, who had been busy all morning, stretched his waist and found that the child was already asleep. He couldn't help but took out two bananas. He was in a hurry to go out... He forgot to bring his lunch, he just brought some fruit.

no way...

Let's eat together.

suddenly,

The door of the office was opened, and Yang Xiaoman walked in with a dark face, carrying a takeaway.

"Did you starve to death?" Yang Xiaoman gave Xu Mang a blank look, and said angrily, "I don't bring food when I go out in the morning, so I left in a hurry... Idiot!"

"hey-hey!"

"My wife, you're so kind." Xu Mang said with a smile, "Oh? It's braised pork?"

"..."

"Did the baby make trouble?" Yang Xiaoman took out the vegetables and rice from the bag, and said seriously: "In an unfamiliar environment."

"No."

"I also told the child about the concept of time dilation in the theory of relativity and the concept of ion traps." Xu Mang smiled and said, "You listened seriously!"

Yang Xiaoman: #￣￣#

this moment,

A song appeared in Xiaoman's mind... Children, do you have a lot of question marks?

after lunch,

Xiaoman originally planned to tease the children for a while, but seeing that they were sleeping so soundly, and couldn't bear to disturb their dreams, she could only quietly leave the research institute.

Subsequently,

Xu Mang started working, but the work fell into a stalemate. Regarding the design of the new ion trap, the progress was a little slow.

"What should I do?" Xu Mang sighed, staring at the computer boredly, feeling a little dazed for a moment.

"Yeah... woo... ah..."

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, teasing her constantly, and said, "Do you miss Dad?"

Facing Xu Mang's question,

Xu Man kept talking about herself, as if she wanted to express something, maybe it was her love for her father.

Snapped,

A crisp sound,

Xu Man's fussy little feet kicked the keyboard, which instantly made her cry.

"Don't cry, don't cry!" Xu Mang was also anxious, slapped the keyboard hard, and said, "Dad has already called you back, let's not cry, don't cry..."

At this time,

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

Just after reading the abstract, Xu Mang suddenly realized.

Yup!

Wouldn't that work?

"Xu Man!"

"You are really Dad's caring little padded jacket!" Xu Mang rubbed his face affectionately against his daughter's little cheek, and said excitedly, "Your foot...directly solved a puzzle in Dad's heart!"

Xu Man:? ? ?
