American TV Series: Starting with Sheldon’s Wool Collection

Later, during the Mathematical Olympiad study time, Teacher Sharon entered the classroom with a cold expression on her face.

Her eyes also deliberately avoided Katie during the lecture.

This situation made the atmosphere in the study room extremely depressing.

The Mathematical Olympiad team members who knew a little bit about the conflict between Teacher Sharon and Katie also behaved very well in this class, fearing that they would offend the teacher.

After the Mathematical Olympiad study was over, even Captain Kevin, who was always very lively, quietly escaped from the classroom this time.

After a while, Sharon, Katie and Mike were the only three people left in the classroom.

Seeing that Teacher Sharon was about to leave with the lesson plan in her arms, Katie hurried over to greet her.

"Teacher Xue, Sharon, I'm sorry for spreading rumors about you before. I'm sorry~" After Katie apologized sincerely, she handed over another letterhead.

Obviously this time to apologize, Katie chose to do both.

Teacher Sharon looked at Katie expressionlessly, and then read the letterhead in her hand.

"Your main task now is to study, and I can't take care of other things. So, you can take care of yourself~" After reading the letter and signing it, Teacher Sharon still looked cold.

After saying those words, she didn't look at Katie again, leaving only the girl's back.

"Did the teacher forgive me?" Katie asked uncertainly.

Judging from Teacher Sharon's reaction just now, Katie, one of the parties involved, had no idea what the other party meant.

As a bystander, Mike could see clearly that although Teacher Sharon didn't show it clearly, he could still feel that she had forgiven the girl.

"Don't worry, Katie. The teacher has forgiven you." Mike replied aloud.

"Really?" Katie was still unsure: "Looking at the teacher's expression, it seems that's not what he meant..."

"Then what do you want? Teacher Sharon's expression has always been like that. Is it possible that you still want her to give you a hug?" Mike smiled and shook his head, then stretched out his arms and joked: "Here But I have a hug that can give you comfort."

"Thank you~" After being reminded, Katie's heart was finally opened. Then, the girl took the initiative and threw herself into Mike's arms.

…

The time has come this Friday afternoon, which is the time for Dr. Ronald’s open class in Melford.

On this afternoon, the school canceled all outdoor activities and allowed students to gather in the big meeting.

Among the huge crowd of students, little Sheldon, who is full of enthusiasm for science, once again grabbed a seat in the front row and in the middle.

"What's wrong, Mike? You don't look happy." Little Sheldon, who was excited, looked at Mike, who was looking very out of sorts.

"It's okay, I'm fine..." Mike shook his head.

In fact, he wasn't having a good time this week. Since their relationship with Regina was exposed, Katie and the other girls, although they didn't say anything about it, felt a little knotty in their hearts.

Among them, Karen had the strongest reaction.

In order to appease several girls, Mike had put in a lot of effort this week, and his body of over 200 people was almost unable to bear it.

"It's okay~" Little Sheldon cared about others for a rare time, and then continued: "Tell me what Dr. Ronald will tell us."

Little Sheldon, who loves scientific knowledge, has been looking forward to this day for a long time.

He hoped that he could learn some useful knowledge from Dr. Ronald today.

"In aerospace knowledge, there should be a lot to talk about, such as rocket launch, thrusters and recovery." Mike said casually.

Listening to the other party's story, little Sheldon's eyes became brighter and brighter, and he was even more looking forward to the next lecture.

Dr. Ronald did not make the students wait any longer. After everyone was seated neatly, the door of the large conference room was pushed open.

Accompanied by Principal Tom, Dr. Ronald walked into the large conference room.

He is only a little over 1.6 meters tall, with a chubby figure and a slight hunchback, and most of the hair on his head has fallen out.

The image of Dr. Ronald broke the students' previous illusions.

Mike vaguely heard a disappointed sigh from the girls behind him.

Little Sheldon on the side became even more excited after seeing Dr. Ronald. The other party's appearance was in line with his guess about the image of a scholar.

"Hello everyone~" Dr. Ronald greeted the students humorously.

It can be seen that this doctor of aerospace science in his fifties has a very easy-going personality.

"I'm Ronald from the Houston Space Agency, and I'm currently in charge of a Mars landing plan..." Ronald introduced himself to his classmates very skillfully.

The clever self-introduction also helped the doctor attract the attention of the students.

"Everyone knows that there is no gravity in outer space. So how do our astronauts live?" Dr. Ronald obviously does not think that high school students can understand profound aerospace knowledge.

Therefore, he chose to tell the students some strange things in space, such as how astronauts solve problems such as drinking water and eating on the space station.

This kind of interesting knowledge is easy for Ronald to talk about, and students also like to listen to it.

Following Dr. Ronald's humorous explanation, bursts of laughter could be heard from the students in the large conference room.

In a cheerful atmosphere, Ronald fulfilled his promise to his old classmates, and Principal Tom diverted the students' attention. The students also gained joy in this open class.

In this way, this event can be regarded as a win-win-win.

However, little Sheldon below, listened to Dr. Ronald's story, his little face wrinkled up.

He couldn't believe it. This was the aerospace lecture he had been looking forward to for a long time. What Dr. Ronald is talking about now cannot be said to have nothing to do with aerospace science. It can only be said that it is perfunctory.

So, little Sheldon raised his little hand resolutely.

"Oh, there is another kid here~" Dr. Ronald used his exaggerated tone again, earning himself another burst of laughter. Then, he said: "Kid, do you have any questions?"

Little Sheldon was very dissatisfied with being treated like a child. However, he was still patient and said: "Dr. Ronald, I want to know some more useful knowledge. For example, the theory or formula of rocket launch is fine."

After Little Sheldon failed to study rockets last time, he became very concerned about the problem of rocket launch.

However, his immature face did not receive enough attention from Dr. Ronald.

"You are still young, these shouldn't be your concerns." Ronald smiled and continued: "How about I tell you how astronauts use the toilet in space!"

Thinking of the scene where there is no gravity in space and poop is floating in the air, the students laughed again.

"No, I don't want to know about the toilet problem. I just want to know how the rocket lifts off." Little Sheldon felt insulted and his little face tensed up.

"Okay, okay~" Dr. Ronald waved his hand as if coaxing a child, and then asked: "Is there anyone here who can answer this child's question?"

Obviously, Dr. Ronald at this moment was still thinking about stimulating the atmosphere at the scene. In his heart, he didn't think anyone could answer this question.

"Three stages of advancement~" Mike said aloud when he couldn't stand the other party's bullying of children.

"Huh? Interesting..." Dr. Ronald understood what Mike said, and he asked with interest: "Can you tell me more about it?"

Current rocket launches have not yet developed into multi-stage propulsion methods. To the ears of professionals, Mike's proposal was very forward-thinking.

"The three-stage propulsion method not only divides the thruster into multiple stages for assembly, but when one stage of advancement is completed, the thruster can be separated and recycled..." Mike explained the rocket stage propulsion theory.

Rocket lift-off places high demands on thrusters, and multi-stage propulsion can theoretically help reduce rocket weight at different time periods.

Once this theory can be maturely applied to aerospace, it will definitely save the space agency a lot of expenses.

"A very interesting guess..."

After listening to Mike's story, Dr. Ronald thought for a while. However, in the end he shook his head and said: "Unfortunately, our current technology cannot meet that requirement..."

Multi-stage propulsion can theoretically save a lot of costs, but the technical requirements are also more stringent.
