In the afternoon, Xiang Nan was writing a paper on "The Orbits and Resonance of Neptune's Satellites."

This paper was published in 2020 by a team from the California Institute of Technology and the Jet Propulsion Laboratory. It details the trajectory and orbital resonance of Neptune's satellites.

This paper has deepened people's understanding of Neptune and can be said to be a very valuable article in the study of Neptune.

Just then, there was a knock on the door.

"The door is unlocked, please come in." Xiang Nan responded loudly without raising his head.

"Hi, Raj." Leonard poked his head in, "Are you busy?"

"It's okay, just doing some research." Xiang Nan smiled and closed the notebook, "What do you want?"

"I have nothing to do, I just came to see you." Leonard also smiled, and then asked tentatively, "Are you still angry with Sheldon?"

"Of course I'm not angry anymore. Why should I be angry?" Xiang Nan waved his hand.

When friends make friends, they get together or break up. His real age is thirty-two years old. He has experienced many separations and reunions, and he has long since looked away from such things.

What's more, Sheldon doesn't have that many advantages that make him think about him all the time. So it's just a break, there's nothing to be pretentious about.

"In that case, let's come to my house for dinner together in the evening. After dinner, we will play "Dungeons and Dragons"." Leonard said happily when he saw what he said.

"I'm sorry, Leonard, you misunderstood." Upon hearing this, Xiang Nan waved his hands and said, "I said I'm not angry because I don't mind breaking up with Sheldon, not because I want to get back on good terms with him."

"Please, don't be like this, we are all friends." Leonard frowned again when he heard what he said.

"He compared us to tools! This is not what friends say." Xiang Nan shook his head.

"You know, he didn't mean it that way." Leonard defended Sheldon.

"On the contrary. Sheldon won't lie, he speaks his mind." Xiang Nan waved his hands and said, "In his eyes, we are tools. If he doesn't change this view, put us

On an equal footing, it is impossible for me to be friends with him again."

"Don't be like this." Leonard was embarrassed.

He has not had many friends since he was a child, and he really cherishes this friendship.

"Leonard, don't worry. Although Sheldon and I can no longer be friends, I will always be your friend, and this will never change." Xiang Nan comforted him.

"Thank you." Listening to him say this, Leonard felt much better.

…

For the next two days, Xiang Nan and Howard sat separately from Leonard and Sheldon, so the foursome were considered separate.

When Xiang Nan and Sheldon met again, they treated each other as nothing, and just passed by without saying hello or nodding.

…

Two days later, Xiang Nan's paper "Edgeworth-Kyber Belt Debris Disk" was successfully published in the "Astrophysics" magazine, and subsequently caused a sensation in the industry.

The new algorithm disclosed in the paper provides a very good tool for people to study the Kuiper belt. It can be said that it laid the foundation for studying the Kuiper belt in one fell swoop. As a result, Xiang Nan's status in the industry has increased sharply.

Although he had some scientific research results before, he did not have much influence after all, so he was still a little transparent in the industry.

Now, he has come up with such groundbreaking research results, which makes people admire him and at the same time, they can't help but respect him.

Now when he goes to the cafeteria to eat, many colleagues pay him attention.

"Wow, did you notice that Mandy Zhou was peeking at you just now?" Howard said to Xiang Nan excitedly.

"Yeah, it's not bad." Upon hearing this, Xiang Nan nodded and smiled.

Mandy Zhou is a very beautiful Chinese-American beauty, and she is also an excellent marine biologist.

"Hey, buddy, you already have Penny." Howard saw his reaction and immediately reminded nervously, "Mandy is mine, and I want to get lost in her Bermuda Triangle."

"Howie!" Seeing how wretched he was, Xiang Nan couldn't help scolding him.

"I'm sorry~" Howard smiled.

At this moment, Leonard and Sheldon also came to the cafeteria carrying meals.

"Well, this is a good opportunity." Leonard's eyes lit up and he looked at Sheldon and said, "Let's go over and say congratulations to him, and then everyone can eliminate the misunderstanding and continue to sit together."

"Sorry, I'm not interested." Sheldon simply refused.

"Okay, then I'll go by myself." Seeing what he said, Leonard had no choice but to change channels.

"You are not allowed to go either. Rajesh and I have broken off diplomatic relations. We are now on opposite sides. As my friend, how can you associate with him and stand on the same side as him?" Sheldon said plausibly.

"Raj is also my friend." Leonard nodded and said, "I'm going to go anyway, you can come or not."

"Okay, you also received a warning." Sheldon threatened.

"You want to take the bus to school tomorrow, right?" Leonard turned around and glanced at him.

Sheldon gritted his teeth, but finally didn't insist.

…

"Hi, Raj, congratulations!" Leonard then walked up to Xiang Nan and said.

"Thank you." Xiang Nan smiled and nodded, "Let's sit together."

"Hmm..." Leonard glanced at Sheldon not far away, his expression hesitant.

"Okay, it doesn't matter." Xiang Nan waved his hand and said with a smile, "By the way, Penny wants to have a party for Halloween, you are welcome to come."

"Halloween party?! Do you need to dress up?" When Leonard heard this, his eyes lit up and he asked with a smile.

"Of course." Xiang Nan nodded.

"What kind of cross-dressing theme is it, movies, animations, comics, dramas, myths..." Leonard asked in detail.

"As you like, there are no restrictions." Xiang Nan smiled.

"Okay, I will definitely participate." Leonard said excitedly.

"Raj, are there girls at the party?" Howard asked with concern.

"Of course, Penny's friends will come." Xiang Nan nodded.

"Wow!" Hearing what he said, Leonard and Howard became even more excited. They left the party empty-handed last time, and they must not make the same mistake again this time.

"Okay, you two listen to me, if you want to catch a girl, don't dress up in all kinds of weird ways." Xiang Nan reminded him immediately when he saw this.

In the play, at Penny's Halloween party, Leonard dressed up as Frodo from "The Lord of the Rings" and Howard dressed up as Robin Hood, but his appearance was quite similar to the fairy tale character Peter Pan.

These two people were quite silly and failed in their disguises, which resulted in them being left out in the cold that night.

"What do you mean?" Leonard Howard asked in confusion.

"What I mean is, it's best to dress up as characters that everyone knows and know. This will make you more popular." Xiang Nan pointed out, "For example, Leonard, you can dress up as Harry Potter, Hao

You can dress up as Captain Jack Sparrow."

"Yeah." They both thought for a moment and nodded.
