Chapter 568: Tool man (two/three)

The weather in July was quite hot. Xu Mang was quite afraid of heat. At this time, he was wearing a sun hat, a polarizer for driving, and a mask by the way. Basically, he was fully equipped for barbecue. Xiaoman was heartbroken for his husband, so he added it temporarily.
but
This makes it even hotter, airtight and stuffed with the heat directly.
At this moment,
Xu Mang and Chenxi just set up a barbecue grill, poured a little gasoline on the charcoal, and quickly burned, but the two men worked the whole time. The other two boys were sitting on the side like uncles. Not moving.
"Chenxi?"
"What's the situation with your friend?" Xu Mang had a big opinion on this, and said helplessly: "What's the background?"
""
"Both are rich second-generation, and they are very good at reading, plus studying in the Ivy League, naturally feel that they are higher than others." Chenxi glanced at the two boys: "These two people seem to be from the University of Pennsylvania. Still majoring in astrophysics."
Xu Mang:? ? ?
Damn it!
So awesome?
However, according to Xu Mang's knowledge, the astrophysics major is ranked first in the United States, with Princeton University ranking first, California Institute of Technology second, University of Chicago third, and the University of Pennsylvania ranked twelfth in this major.
Not good,
"that"
"Where are the two girls?" Xu Mang asked curiously, "What school do you study? What major?"
"Uh"
"One Harvard, another Yale." Chenxi said: "Mathematics and physical optics, in short, these people are all sciences, and you are similar to Brother Mang."
at this time,
Xu Mang suddenly thought of the problem he was encountering. It is estimated that the wire metamaterials cannot be achieved by these four people alone, but it can assist in calculating various data of celestial bodies outside the department, which can solve the problem of oxygen fugacity.
Not bad, this barbecue is a bit rewarding!
But it seems that the four of them are very arrogant, and they need to be convinced.
"Chenxi?"
"If I say that I am Xu Mang, and now I want you to participate in a research project, do you think your four friends will join this research project with admiration?" Xu Mang asked cautiously.
"I don't know how to try it." Chen Xi said.
Try?
What if others are unwilling?
Isn't it very embarrassing?
Xu Mang doesn’t make jokes about his own face. Face is more important than fate these days. He blindly reveals his name. In case of rejection by others, this is more than simply losing face. According to his own personality, he will swallow it in the next second. Shit committed suicide.
Forget it,
Let's take one step at a time, but these four tools are really easy to use.
soon,
The barbecue meeting was officially launched. According to the previously stated labor distribution situation, the four boys gathered around the barbecue stove and started the so-called grilled food. Xu Mang basically grilled vegetables. Yang Xiaoman didn't like meat, especially It's this kind of smoked meat.
According to Xiaoman, if you eat more barbecue, you will get angry. When you get angry, you will get acne on your face, and when you get acne, it will become unsightly. Then you need to use various acne products, and you must be very careful. Let acne marks remain. In short, acne is very painful for Xiaoman.
have to say,
Xiaoman is just an ordinary girl. Although she has an angelic face, she is praised by many people who eat melons as an angel who fell into the mortal world. Despite the kind of chest that touches the ground, Xiaoman will eventually have all the same women. Troubles.
But this girl is very real, at least Xu Mang likes such a girl very much, if everything is impeccable, then what's the point?
"Two brothers?"
"Your last name?" Xu Mang asked with a smile.
"Minggui surnamed Tong, a single name is Min." The boy with glasses, who was particularly gentle, said blankly.
"My last name is Lu, and my single name is Bo." The boy who looked equally gentle said calmly.
Xu Mang:
How does it feel that something is wrong
Ugh?
Is this being pretended?
Faced with a cold reply, Xu Mang did not continue to attend to the two of them, and silently made a barbecue for Xiaoman, who was in the shade of the trees. At this moment, the noble Professor Xu became the exclusive toolman of the violent airport.
呲呲呲,
After brushing a layer of oil and turning the corn over, Xu Mang sat in a chair and waited for the corn to change due to the high temperature.
"Tong Min?"
"A subject that the professor gave us is based on the metric of the expanding universe s^2^2^2^2^2^2, where the possible curvature of space is ignored, and the specific form of the function depends on the material content in the universe."
"Then how to solve the next four problems?" Lu Bo asked curiously while grilling skewers: "I think these four questions are a bit too much. The first problem is that the particle whose mass is calculated as 0 is 0. The ratio of energy and momentum at a moment as a function of time."
"Ugh!"
"This is the first question, and it is already outrageously difficult. The following three prove that the thermal equilibrium is composed of interacting, massless particles, and the universe composed of mass particles does not maintain thermal equilibrium, which determines the neutrino Speed ​​and energy issues"
"Isn't this terrible?" Lu Bo said in pain, "I feel that the professor is playing with us. This is the knowledge of astrophysics. This is the content of theoretical physics. I have asked that this is about relativity cosmology. content."
Tong Min smiled bitterly, and said silently, "What can we do? This is an assigned topic. An explanation must be made and calculations and textual explanations must be made, and credits are credited to it. It is the same as encountering this kind of neurosis. Professor, I can only admit it's bad luck."
Suddenly,
The anger became a little serious.
"Ugh?"
"Will Liu Yan and Zhao Pengpeng help us solve these problems?" Lu Bo said: "It involves a lot of mathematics. It happens that Liu Yan is a graduate student in the Department of Mathematics at Harvard. Aspect is not a problem."
"but"
"We are grilling." Tong Min was persuaded, but in this situation, it is a bit rude to others not to grill but to solve the problem of relativity cosmology.
"Chenxi"
"Thank you and your buddies to help us bake the leftovers." Lu Bo said helplessly: "Now Tong Min and I are ants on a hot pot. It is rare to meet Liu Yan and Zhao Pengpeng. They helped us solve the problem, sorry."
Chenxi’s anger, the special labor and management are looking for you to have a barbecue. What kind of cosmic problems did you run over to solve? What matters to the two of you in the cosmos? Even if the cosmos is about to be destroyed, isn’t there a reunion, they will save The universe!
"go Go!"
Xu Mang smiled and said, "What do you want to eat? I will bake it for you."
Seeing Xu Mang with a charitable face, Tong Min and Lu Bo's heart for him rose sharply.
"whatever."
"Tong Min and I can eat anything, thank you buddy!"
Words fall,
The two left the barbecue stove.
Looking at the backs of the two of them, Chen Xi asked with a full face of doubt: "Brother Mang has let them go?"
"It doesn't matter."
"These four people can't solve it." Xu Mang said with a smile: "Say, what major did you study in Magic City Normal University?"
"Uh"
"It's just a mess. My dad arranged for me to go to the United States. I don't want to insist on staying here." Chen Xi said: "This is not a big problem. The main thing is that I can't help Tianmei. Her grades are better than those of Tsing Hua University and Peking University. , And finally came to Jida to study."
"They are all prestigious schools."
"In fact, there is no difference." Xu Mang smiled: "If you feel a little guilty, please add more to Guo Tianmei in the future. By the way, your sister Xiaoman is particularly dissatisfied with your approach, 20,000 yuan. The bag dismissed Tianmei. At that time, your sister Xiaoman almost exploded."
Chenxi shrank his head and said cautiously: "Will I be beaten?"
"That's not enough."
"You can't get away with a meal." Xu Mang said seriously: "Don't have any grievances. Sister Xiaoman is such a person. The more you care about, the more irritable she will be. Punch, this is how your sister Xiaoman cares about people."
Damn it!
Hard work, brother man!
"Brother Mang?"
"What level are you now?" Chenxi asked curiously: "I often see you on the news, and now I have put the awards you received in the most conspicuous position. I think the principal can't wait to take you. The head is posted on the school building."
"Ha ha"
"The level of an internationally renowned scientist." Xu Mang said indifferently: "There are too many titles to count."
Upon hearing Xu Mang's words, Chen Xi couldn't help but sigh with emotion, pretending to be forced, Xu Mang's brother is basically invincible.
at the same time,
Yang Xiaoman and Guo Tianmei were hiding in the shade of the trees and chatting. Suddenly they saw two barbecue tool men sitting next to the other two returnee girls with chairs. The four of them started discussing what the problem was, even with their bags. He took out the tablet and began to analyze the problem.
what's the situation?
Don’t cook well, suddenly started to solve the problem?
Is it
Are all the students so boring?
Does barbecue need to be calculated accurately?
"what's the situation?"
"What's the matter with these four guys?" Yang Xiaoman frowned, and asked Tianmei next to him: "What the is getting together?"
"do not know."
"But one thing is for sure, these four people are not interested in barbecue." Guo Tianmei said: "In short, these four people are very high-end, especially the two boys, do not understand the concept of pulling out black holes, and then the four of them are just this. The concept has been fighting for a long time in the car, it seems I don’t know what the problem is, it seems to be a calculation problem.
"cut!"
"It's not that I deliberately belittle these four people, your brother Xu Mang is an authoritative expert in this field." Yang Xiaoman said with a disdainful expression, "Forget it, ignore these four people, anyway, it's not the same person. "
on the other side,
Tong Min, Lu Bo, Liu Yanhe and Zhao Pengpeng were in a difficult situation. The four of them were not interested in barbecue. They took this opportunity to solve the problem of the concept of expanding universe in relativity cosmology, but the four encountered obstacles.
One problem is already a tragedy. If the energy and momentum are respectively 0 and ~EbookFREE.me~assuming 00, the particles will travel freely except for the influence of the above metric. How can we calculate the ratio of energy and momentum to time?
How can the thought kinetic energy of particles be described as kinetic energy?
From the ^2r constant, how to calculate the particle energy?
The four of them were in an awkward situation when calculating the functional relationship between the energy, momentum and time of the expanding universe.
Half an hour,
For half an hour, there was no clue.
At this time,
There was a voice behind him.
"Your lamb skewers are ready!"
Xu Mang was holding a handful of lamb skewers, standing on the side with a smile on his face, suddenly stretched his head to look at the calculation process in the hands of the four, and asked curiously: "What are you doing?"
