I really don't want to lie down and win

"Don't tell me..."

"I've really thought about what the soul is." Xu Mang said with a smile: "First of all, I think about it from a scientific point of view, and it doesn't involve any metaphysics. If you use metaphysics to argue with me, then I won't talk about it. There's no way...I can't come!"

"first..."

"The soul shouldn't exist in a physical form, otherwise scientific instruments would have detected the soul long ago. The Internet doesn't say that it weighs 21 grams after hanging up. Many people think it's the quality of the soul." Xu Mang said seriously: "This must be a substance. Form, so the 21-gram soul weight statement is not valid."

"If it's in the form of energy, according to the mass-energy equation...the 21 grams lost is enough to roast hundreds of millions of tons of boiled water." Xu Mang shrugged: "Do you think it's possible?"

"Since it's not matter...what is it?"

"Speaking of which, we have to come up with the paradox of the Ship of Theseus, assuming that the components of an object are replaced, but is it still the original object?" Xu Mang said: "Actually, this paradox has always existed in us. "

who am I?

where am I?

Why should I listen to this stuff?

Almost everyone was dumbfounded. It was originally a half-joking question, but... never expected that Academician Xu Mang really...really thought about the question of the soul, and gave many points of view.

Even what...the mass-energy equation and the paradox of the Ship of Theseus have been taken out, this... how boring is this usually?

"Except for the neurons in the brain, the cells in the whole body of a person will be replaced every few years." Xu Mang said seriously: "Actually... the soul is very similar to this, it doesn't care about the category, but about the type connection method."

"When discussing the ontology of a thing, apart from its materiality, one cannot fool what kind of combination of mentality makes up the material." Xu Mang said while wrapping a roast duck: "Here I need to quote quantum mechanics, in quantum mechanics ...materiality is not that important."

"why..."

"Because the concept of identical particles refers to particles with exactly the same intrinsic properties, such as electrons, protons, neutrons, photons, mesons, etc., they can be elementary particles or composite particles composed of elementary particles."

Xu Mang seemed to have found the feeling he used to have, but when he saw the bewildered expressions on everyone's faces, he understood... Maybe they didn't understand the following content. He originally wanted to talk about the concept of body differences, but now Looks like it might not work.

"What is a soul?"

"My concept... is memory!" Xu Mang said, "Because memory is the change of neurons in the brain, the only thing that does not change, then someone will definitely ask... what is will, sorry... again It involves quantum mechanics."

"Here we're going to talk about true randomness, the concept of parallel universes, and quantum processes...it's too complicated, and you won't understand even if I tell you, so let's stop here." After Xu Mang finished speaking, he put a roast duck in his mouth.

"..."

"..."

"..."

After listening to a class given by a Nobel laureate, life is full of all kinds of confusion. In other words, does Academician Xu look at everyone like an idiot?

This... How can I understand this?

"Ugh?"

"Shall I explain the twin paradox?" Xu Mang had a whim, and hurriedly said, "This is interesting... A thought experiment about special relativity is that there are a pair of twin brothers, one of whom steps on a spaceship to make an experiment. Long-distance space travel near the speed of light while the other stays on Earth."

"As a result, when the traveler returned to Earth, we found that he was younger than his brother who stayed on Earth..." Xu Mang began his long speech, starting from the assumption at the beginning, leading to the time dilation effect, and then deriving it. ..

he's hi

I was so excited, I haven't been in such an active and excited state for a long, long time.

"..."

"Xiaoman... Hurry up and stop it!" Sitting next to Yang Xiaoman, Wang Shao's wife said in a very low voice: "Look...everyone is miserable!"

"I..."

"Let him talk for a while. Since I was pregnant, he has stayed by my side to take care of me. For nearly a year, he has been suffocated." Yang Xiaoman smiled bitterly, and said helplessly: "Today Finally found an opportunity to let him vent, almost I will stop."

10 minutes later,

Xu Mang finished talking about the paradox of twins, and then thought of a new topic, what would happen to the earth when the sun disappeared.

"All right!"

"It's almost enough!" Yang Xiaoman was also having a very difficult time. He gave Xu Mang a direct look and said seriously, "I'm here for dinner, not to listen to your class."

"..."

"Okay, okay." Xu Mang sighed, obviously feeling a little unfinished.

dinner is over,

Entered the stage of the symposium, but Xu Mang was kicked out of the symposium because he went too far before. Standing alone in the middle of the courtyard, thinking about life while smoking a cigarette, the only one who can make him so honest is Yang Xiaoman.

no way...

Good guy, it's only been half an hour, and everyone is autistic, the terminator of the topic, how can this kind of person join the symposium, chatting to death every minute, he is not fooling around, but serious, this The most annoying.

after an hour,

it's over,

Xu Mang took Xiaoman and the child to go home, but it was only eight o'clock, and the nightlife had just begun. Yang Xiaoman wanted to take the child to the mall.

"Ugh?"

"Would you like to go shopping?" Yang Xiaoman asked: "Let's go shopping as a family of four, anyway, we don't have anything to do right now."

"Stop it."

"Every time you go out, you have to encounter messy things. Isn't it good to stay at home?" Xu Mang frowned and said, "Speaking of which, what's there to do at night?"

"going or not?"

"Go! Go! Go!"

quickly,

arrived at the destination,

The family of four was shopping happily, and at this moment, Xiaoman suddenly thought of something.

"Ugh?"
