American TV series: Start with the little Sheldon's wool

Chapter 131 Computers
Later, during the Mathematical Olympiad study time, Teacher Sharon entered the classroom with a cold expression on her face.

When she was lecturing, her eyes also intentionally avoided Katie.

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

And the Math Olympiad players who knew a little bit about the conflict between Teacher Sharon and Katie also behaved very well in this class, for fear of running into the teacher's bad luck.

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

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

Seeing that Teacher Sharon was about to leave with the lesson plan in her arms, Katie hurried over to meet 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, do it yourself~" After reading the letter, Teacher Xue Lun still had a cold look.

And after she finished speaking, she didn't look at Katie again, only leaving the girl with a back view.

"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 not sure: "I see the teacher's expression, it doesn't seem to mean that..."

"Then what else do you want? Isn't Teacher Sharon's expression always the same? Could it be that you still want her to give you a hug?" Mike shook his head with a smile, then stretched out his arms and joked: "Here There is a hug that can comfort you."

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

……

The time came to this Friday afternoon, which is the time for Dr. Ronald to open his 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, this week, he didn't have a good time.Since the relationship with Regina was exposed, Katie and the girls didn't say anything, but they felt somewhat uncomfortable.

Among them, Karen had the strongest reaction.

In order to appease several girls, Mike has made great efforts this week, and his body with a physique of more than 200 is almost unbearable.

"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 very much hoped that today, he could learn some useful knowledge from Dr. Ronald.

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

While listening to the other party's narration, Little Sheldon's eyes became brighter and brighter, and he looked forward to the next lecture even more.

Dr. Ronald didn't make the students wait any longer.After everyone sat neatly, the door of the large meeting 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 fat body and some hunchbacks, and more than half of the hair on the top of his head has fallen out.

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

Mike vaguely heard the disappointed sighs of 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.

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

It can be seen that this 50-year-old doctor of aerospace science has a very easy-going personality.

"I'm Ronald from the Houston Aeronautics and Space Administration, and I'm currently in charge of a Mars landing plan..." Ronald introduced himself to the students skillfully.

The ingenious self-introduction also helped the doctor to 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 didn't think that high school students could understand the profound space knowledge.

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

This kind of very interesting knowledge was easy for Ronald to explain, and the students liked to listen to it.

Following Dr. Ronald's gag explanation, bursts of laughter came from the students in the large conference room.

In a cheerful atmosphere, Ronald fulfilled his promise to his old classmates. Principal Tom diverted the attention of the students, and the students also had fun in this open class.

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

However, the little Sheldon below, listening to Dr. Ronald's narration, wrinkled his little face into a ball.

He couldn't believe that 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 astronautics, it can only be said to be perfunctory enough.

So, Little Sheldon resolutely raised his little hand.

"Oh, there's another kid here~" Dr. Ronald once again won a burst of laughter for himself with his exaggerated tone.Then he said, "Little friend, do you have any questions?"

Being treated like a child by the other party made Little Sheldon very dissatisfied.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 get 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 the principle of rocket lift-off." Little Sheldon felt that he was insulted, and his little face became tense.

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

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

"Three stages of advancement~" Mike said aloud, unable to 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 divides the propeller into multiple stages and assembles it. After one stage of propulsion is completed, the propeller can be separated and recovered..." Mike explained the theory of rocket stage propulsion.

Rocket launch has high requirements on propellers, and multi-stage propulsion can theoretically help rockets lose 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.

"An 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.
