Meanwhile, young Sheldon became even more excited upon seeing Dr. Ronald. The man's appearance perfectly matched his preconceived notion of a scholar.
"Hello everyone!" Dr. Ronald greeted the students with a humorous tone.
It is clear that this aerospace doctor in his fifties has a very easy-going personality.
"I'm Ronald from NASA Houston, and I'm currently in charge of a Mars landing program..." Ronald skillfully introduced himself to the students.
A clever self-introduction also helped the PhD student capture the students' attention.
"Everyone knows there is no gravity in outer space. So how do our astronauts live?" Dr. Ronald clearly didn't think high school students could understand such complex aerospace knowledge.
Therefore, he chose to tell his students some strange and wonderful stories about space, such as how astronauts solve problems like drinking water and eating on the space station.
Ronald makes this kind of interesting knowledge easy to explain, and his students love listening to it.
As Dr. Ronald delivered his witty and humorous presentation, bursts of laughter filled the large conference room.
In a cheerful atmosphere, Ronald fulfilled his promise to his old classmate, while Principal Tom used this opportunity to divert the students' attention, and the students also gained joy from this open class.
All things considered, this event can be considered a win-win-win situation.
However, little Sheldon below, listening to Dr. Ronald's story, scrunched up his face.
He couldn't believe this was the aerospace lecture he had been looking forward to for so long. Dr. Ronald's lecture wasn't entirely unrelated to aerospace science, but it was certainly perfunctory.
So, little Sheldon resolutely raised his hand.
"Oh, there's another little one here~" Dr. Ronald's exaggerated tone earned him another round of laughter. Then he said, "Little one, do you have a question?"
Being treated like a child made young Sheldon very unhappy. However, he still patiently said, "Dr. Ronald, I want to know some more useful knowledge. For example, the theory or formulas of rocket launch would be helpful."
After his previous rocket research failed, young Sheldon became very interested in the issue of rocket launches.
However, his youthful appearance did not receive enough attention from Dr. Ronald.
“You’re still young, these aren’t things for you to worry about.” Ronald smiled and continued, “How about I tell you how astronauts use toilets in space?”
The thought of poop floating in the air because there is no gravity in space made the students laugh again.
“No, I don’t want to know about toilets. I just want to know how rockets launch.” Young Sheldon felt insulted, and his face tightened.
"Alright, alright~" Dr. Ronald waved his hand as if coaxing a child, and then asked, "Is there anyone here who can answer this child's question?"
Clearly, Dr. Ronald was still focused on creating a lively atmosphere. He didn't believe anyone could answer the question.
“The three-stage approach!” Mike said, unable to stand by and watch the other party bully the child.
"Hmm? Interesting..." Dr. Ronald understood Mike's words and asked with interest, "Could you elaborate?"
Current rocket launches haven't yet developed into multi-stage propulsion systems. To experts, Mike's proposal was remarkably forward-thinking.
“The three-stage propulsion method divides the thruster into multiple segments for assembly. Once one stage of propulsion is completed, the thruster can be separated and recovered…” Mike explained the theory of segmented rocket propulsion.
Rocket launch places high demands on the thrusters, and multi-stage propulsion, in theory, can help reduce the weight of the rocket at different times.
Once this theory can be successfully applied to aerospace, it will certainly save space agencies a significant amount of money.
"A very interesting conjecture..."
After listening to Mike's explanation, Dr. Ronald pondered for a long time. However, he ultimately shook his head and said, "Unfortunately, our current technology is not yet up to that requirement..."
Multi-stage advancement can theoretically save a lot of costs, but it also requires more stringent technical standards.
Chapter 132 Computer (Continued)
Every technological innovation in aerospace requires repeated verification, and the human, material, financial and material costs involved cannot be decided by a single PhD in aerospace.
Therefore, while Dr. Ronald thought Mike's multi-stage progression theory was excellent, he also felt that its feasibility was insufficient because the theory was too advanced.
“This student’s idea is excellent. May I ask your name?” Dr. Ronald asked quipped.
He called me Mike.
Below, a group of girls helped Mike answer the question.
“Very good, it seems Mike is quite popular at school…” Dr. Ronald smiled, then continued, “Let’s give Mike a round of applause for his idea!”
Amidst the students' enthusiastic applause, Dr. Ronald also reflected on his own actions.
He realized that he might have been prejudiced against public high school students, thinking that they, who received a happy education, could not understand advanced aerospace knowledge.
However, after listening to Mike's advanced theories, Dr. Ronald realized that even in public high schools, there was no shortage of smart people.
Technological advancements are often driven by a small number of brilliant individuals.
So, in the following time, Dr. Ronald began to explain the knowledge in the field of aerospace.
These obscure and difficult professional terms can be quite boring to outsiders who are unfamiliar with them.
As a result, after listening to aerospace professional knowledge for a while, the students below all became drowsy as if hypnotized, and the atmosphere of the open class became dull.
However, seeing that Mike and a very few other students were listening attentively, Dr. Ronald still chose to explain the entire theory of rocket launch in detail.
As the school bell rang, Dr. Ronald's lecture was drawing to a close. He clapped his hands to recapture the students' attention and said, "Thank you all for patiently listening to this old man's ramblings all afternoon..."
Ronald, now witty again, once more won over his classmates with his witty remarks.
He then continued, "That concludes today's lecture. If any students are interested in aerospace, they can come find me at NASA in Houston..."
As he spoke, Dr. Ronald glanced at Mike in the front row, clearly indicating that his words were pointed at something.
It could also be said that Mike's previous performance earned the approval of this PhD in aerospace engineering.
Next, Principal Tom, who was very satisfied with the outcome of the open class, went on stage to announce the end of the session.
Just as Dr. Ronald was about to leave, Sheldon, who was deep in thought, suddenly got up and chased after him.
“Dr. Ronald, I think there are still some flaws in your theory of rocket launch,” Sheldon interrupted.
It must be said that a brain with an IQ of 187 is very useful. Young Sheldon roughly understood the principles of rocket launches today just through a widely publicized lecture.
Moreover, he also noticed flaws in these complex theoretical formulas.
The reason Sheldon was deep in thought just now was because he was thinking about how to solve these loopholes.
Meanwhile, Dr. Ronald, seeing that it was that inquisitive child again, couldn't help but shake his head.
It's important to understand that existing rocket launch theories are derived from the practical experience of countless experts. Therefore, Dr. Ronald didn't believe that a child could offer any profound insights.
"Oh, what did you find?" Dr. Ronald asked. Although he had a smile on his face, his attitude and tone were still like he was teasing a child.
With his ability to memorize images, young Sheldon quickly recounted the parts he felt were problematic.
Dr. Ronald was also surprised by Sheldon's amazing memory.
However, the problems that Sheldon mentioned are precisely the challenges that countless aerospace experts are currently tackling.
"Do you have any solutions to these problems?" Dr. Ronald asked, half-jokingly.
"This..." This question stumped Sheldon. Even though he was smart enough, he couldn't come up with a solution for the time being when there wasn't enough data and time.
Clearly, a problem that stumps countless experts is not so simple.
"Alright, son. Like I said, these aren't things you should be thinking about right now. Your task now is to grow up properly." Sure enough, Dr. Ronald still treated young Sheldon like a child.
After being repeatedly belittled, Sheldon finally couldn't take it anymore and retorted seriously, "No, give me time, and I will find a way to solve those problems."
"Alright, whatever you want~" Dr. Ronald smiled and shook his head before leaving with the principal.
This casual and perfunctory behavior by Dr. Ronald completely ignited Sheldon's fierce competitive spirit.
He decided to find the right way to make the other party apologize for their arrogance.
“Mike, I think we can talk. Your multi-stage propulsion theory and thruster recovery conjecture should be incorporated into my plan…” Having made up his mind, Sheldon turned to Mike for help.
Having decided to embarrass the other party, Sheldon Jr. felt he had to make his plan the best it could be.
So Mike spent the rest of Friday discussing rocket launch theories with Sheldon.
Although Mike has not specifically studied rocket launches, his [Memory Palace] ability gives him a wealth of advanced theoretical knowledge to discuss.
By dinner time, Mike and Sheldon had come up with a complete plan for rocket launch and booster recovery.
The next step is to organize the large amount of complex data.
"Shelly, what's wrong?" Mary, who had just finished her pre-meal prayers, asked, looking at young Sheldon who was in a daze.
"I'm organizing the data..." Sheldon, snapping out of his daze, said with a sigh, "There's just too much data, and my brain seems a bit overwhelmed."
There are many aspects to consider when launching a rocket, and the amount of data is staggering. Even with Sheldon's brain, it's impossible to take everything into account.
Seeing her youngest son's secretive demeanor, Mary, feeling helpless and unable to offer any assistance, could only shake her head in resignation.
Sitting opposite her, Missy asked curiously, "Data? Is it mathematical calculation? If you can't figure it out, why not use a calculator?"
Missy's innocent words immediately made Sheldon's eyes light up.
Yes, if your brain can't handle the calculations, why not use tools?
When he goes shopping at large shopping malls, young Sheldon loves to examine the computers on display.
Young Sheldon had already mastered basic computer skills on his own. Now, he realized what he needed.
"Dad, can you buy me a computer?" Sheldon asked.
"A computer?" George, who was called upon, thought for a moment and then shook his head in refusal. "No, that thing is too expensive. Besides, we don't need it..."
George had also visited the computers in the mall, and in his memory, they were just large CRT televisions that could be used to play simple games. They had no other function.
Of course, the main reason is that the thing is just too expensive; a single unit costs more than two thousand US dollars.
George, who lost his high-paying job, doesn't believe his family can afford it.
Chapter 133 Money Making Plan
“Why wouldn’t I need it?” Sheldon argued. “With a computer, I can file my family’s taxes much more easily. Plus, the backup program can store our menu. Also, I can chat online with strangers. And I can watch the cartoons I want on it…”
Young Sheldon cleverly pointed out some of the conveniences a computer would bring to his family, thus increasing the persuasiveness of his decision to buy a computer.
Clearly, his argument was very effective.
George was tempted when he heard that a computer would make filing taxes much easier. But after thinking it over, he shook his head and said, "I'm sorry, Shirley. We don't have any extra money to buy a computer."
Upon hearing George's words, Missy, who was looking forward to watching cartoons on the computer, and little George, who was looking forward to chatting online, both lowered their heads.
As Cooper children, they understood the family's difficulties.
Just as the children were feeling disappointed, Mary suddenly said, "Maybe we can pool our money to buy a computer. I have over a thousand US dollars here..."
"What? You actually have a secret stash of money hidden away?" George couldn't sit still after hearing his wife's words.
The Cooper family's finances are very transparent; as far as George knows, their public accounts clearly show they have no money. The fact that his wife can still produce over a thousand dollars proves she's hiding some money.
Mary had only been working at the church for a short time, and her salary was not high.
Therefore, Mary must have had her own savings for a long time. At that time, the only source of income for the family was George's salary.
Therefore, the final conclusion is that Mary used George's salary to save her own money.
This discovery left George, who had been having a rough time at work, feeling very unbalanced.
“This money is all saved from my daily living expenses…” Mary didn’t think there was anything wrong with her saving money on the side. Then, she questioned her husband, “I just don’t believe you don’t have money hidden away.”
"I..." George wanted to say he didn't have any, but what man doesn't have some hidden money? At this point, he stubbornly admitted, "I have three hundred dollars here. But it's all rightfully mine..."
Mary was oblivious to her husband's minor tantrum. She was still thinking, "I have a thousand here, you have three hundred there... plus our current salaries. Maybe by the end of next month, our family will be able to afford a computer."
This shows that Mary took her youngest son's needs very seriously.
However, Mary's unintentional actions also angered George.
George, who already felt increasingly powerless at home, angrily said, "No, you can't take my money. I'd rather use it to buy beer."
Mary still couldn't sympathize with her husband's tantrums. She retorted, "Your health doesn't allow you to drink too much beer. It would be better to use that money to buy a computer; it would be better for everyone..."
"You want to take away my right to drink beer?" George, who has been down on his luck lately, relies on beer to cheer himself up. He's become rebellious towards his wife's demands.
Seeing that George and his wife's argument was escalating and frightening the children, Grandma Connie quickly spoke up, "I have some savings; how about I pay for it?"
In Connie's grandmother's view, buying a computer was the origin of the conflict between George and his wife. Once this problem was solved, the Cooper family's conflict would also be resolved.
However, as the argument progressed, the conflict between George and his wife extended beyond the computer.
Besides, the computer doesn't help Grandma Connie's life at all, so there's no reason for her to pay for it.
