Chapter 149 Congratulations, Dr. Li Qiwei!
When the top brass on the defense committee tried their best and failed to challenge Li Qiwei, others did not dare to hope, even members of the Royal Society.
Everyone understands that in the academic field of physics, there are few problems that can stump the other party.
There were several examples in later generations of the defending students overpowering the reviewing professors.
The most famous of them is the philosopher Wittgenstein.
When he was defending his doctoral thesis, he told the defense team: "You will never understand my thesis."
Then he passed the defense.
The defense team leader at the time was still The famous Russell.
It can be seen that the graduation defenses of geniuses are all unique.
Now, facing Li Qiwei's high-spirited spirit, everyone can deeply understand this feeling.
However, this is just a defense meeting. If it doesn't work, you can still rely on your old skills.
Swan’s old voice instantly attracted everyone’s attention.
"Bruce, your doctoral defense was so wonderful."
"To be honest, looking at your thesis, I always feel that we old guys can't keep up with the times."< br>
“The mechanical analysis and electromagnetic field calculations that I was best at were no longer useful.”
"Sometimes I really want to go back to when I was young, with endless energy to explore the mysteries of physics."
Li Qiwei said with a smile: "Mr. Swan, you are too modest."
" It is precisely because of the older generation like you that we have laid the foundation for the current prosperity of physics."
Swan smiled and then said: "Bruce, I have a question, it is not about your paper. , but about your patent."
"I have studied your tungsten filament patent, and I am very curious, how can you determine that tungsten filament is more suitable for light bulbs without doing verification experiments. ?”
"I think the people in the Cavendish Laboratory will never lower themselves to study the mechanism of light bulbs."
"So, Bruce, do you have any special skills?"< br>
Li Qiwei looked calm on the outside, but he was really panicking inside.
As expected, time travelers can never underestimate people of any era, especially those big guys.
As long as Li Qiwei reveals a little clue, someone will always find something unusual in it.
He could deceive Philips founder Gerard because the other party didn't know what experiments Li Qiwei was doing.
But Swan, a physics veteran with extensive connections and good information, could easily find out what Li Qiwei was doing in the laboratory.
If he had never tested tungsten filaments and directly thought of making tungsten filaments into light bulbs and improving them, that would be too appalling.
After all, there is no theoretical support for this, it is purely experimental.
Li Qiwei did not show any panic, but smiled and said: "Mr. Swan, this is complicated to explain."
"When it comes to when I was still in the Qing Dynasty, I became interested in science when I was a child."
"Although the Qing Dynasty at that time was closed, my family background still allowed me to come into contact with a lot of Western countries. knowledge."
"I was deeply impressed by Mr. Edison's light bulb."
"So I made a home laboratory and did a lot of tests."< br>
“Of course, I didn’t have much basic knowledge of physics at the time, so many things were specious.”
“However, this experience left a deep impression on me.”
“Later, I came to Cambridge to study abroad, and only after studying physics systematically did I fully understand the original experiment.”
“I learned that I had experimented with a material called tungsten.”
“So, through theoretical analysis of materials science, I thought that tungsten filament was a feasible light bulb material.”
< br>“As for some data, it is my experience at that time.”
After some explanation, no matter whether others believed it or not, Li Qiwei himself believed it anyway.
And he is confident. If you have the ability, go to the Qing Dynasty to investigate.
Swan was stunned by Li Qiwei. He tentatively believed him and then nodded lightly.
In this case, there is no need to continue to delve deeper.
However, this incident reminded Li Qiwei that he must be thoughtful when doing things in the future.
After Swann, members of the Royal Society also raised questions.
These older generation of physicists did not make things too difficult for Li Qiwei. They just pointed it out. Among them, Heaviside's question was the most interesting.
“Bruce, I don’t want to take credit with you, but I discovered the existence of a substance in the atmosphere that can reflect electromagnetic waves almost at the same time as you.”
“However, I didn’t publish it at the beginning. Alas, I should have published it in advance.”
Several of Heaviside's friends couldn't help but sigh. They knew that the other party had studied this issue.
Li Qiwei could only smile bitterly. If it weren't for the enhanced memory in his brain, he would not have known about Heaviside at all.
“Mr. Heaviside, I don’t think this thing is an achievement.”
“The atmospheric science developed based on it may be what we should pay attention to.”
“After all, maybe there were physicists who had this kind of speculation earlier before you.”
"I just did some theoretical calculations when I had nothing to do."
"The process is not particularly complicated."
"Professor Thomson did it because he liked me. Take this result as an achievement and pin it on me."
Li Qiwei's humor successfully resolved the embarrassment and made Heaviside feel relieved.
At this time, the defense has basically come to an end.
After all, graduating with a PhD is a momentous moment in life.
When Li Qiwei is already so good, there is no need to be picky.
How about making the entire graduation process more perfect.
So, after Thomson gave the last reminder in the name of his mentor, no one asked any more questions.
Li Qiwei took a deep breath, although he knew that his doctoral defense would go smoothly.
However, when that moment really came, he couldn't help but be excited.
This is a PhD from Cambridge University in 1903, and its gold content is far beyond that of later PhDs.
He may even be the first Chinese to obtain a doctorate. This honor is unparalleled.
With the title of Ph.D. in Physics from Cambridge University, he will return to China to create greater glory.
At this time, Professor Thomson stepped forward and shook hands with Li Qiwei vigorously.
There seemed to be thousands of words in his mind, but when he reached his mouth, there was only one sentence left:
"Congratulations, Dr. Li Qiwei!"
After Li Qiwei heard this title, he suddenly felt a panic. move.
Thomson did not say Dr. Bruce, but Dr. Ridgway, which shows the love and respect hidden deep in his heart.
He respected Li Qiwei’s choice and appreciated his dedication to the country.
There was even a hint of admiration for Li Qiwei, not related to academic achievements, but to ideals and ambitions.
Of course Li Qiwei understood the meaning, so he was very moved.
At this moment, he felt infinite gratitude to Thomson.
The other party treats him with absolute respect.
Thomson was a pure physicist.
Even though Li Qiwei and Rutherford complained that he advised people to marry late, they were all joking.
As a scholar, Thomson's qualities are worthy of learning by everyone.
So, Li Qiwei nodded heavily to him, his complicated eyes full of all the information.
Finally, with the applause of everyone present, Li Qiwei’s doctoral graduation defense came to a successful conclusion.
What remains is the grand doctoral degree awarding ceremony.
However, it was basically just a glorious formality to let people feel the academic atmosphere.
From this moment on, Li Qiwei finally completed the gorgeous transformation of his identity.
He is no longer the Bruce Lee that others say, nor is he Li Qiwei.
But Dr.Li, Dr. Li.
