As Lin Ke was speaking, the various instruments behind him were constantly changing.
Diffraction experiment...
Dispersion experiment of light...
Mechanical wave theory…
Lin Ke told them one by one, and at the same time, the instruments were changed one by one to show the results of these experiments.
So what happened on the field?
At the beginning of the experiment, it appeared that light was a particle. The students could not find fault with the experiment and only felt that light was indeed a particle.
Then we experimented again to see how light turned into waves again.
So the students thought that light should be a wave?
After repeating this process, the students were confused.
Of course, most physics students know this and have supporting theories.
"I have long said that light is a particle! Our dean's meaning is very accurate!"
"That's right! Can't the diffraction experiment prove it?"
"Light is a particle! I said so!"
Some students who support the light particle theory responded to Lin Ke's experiment.
Students from the "light is a particle" group started to clamor when Lin Ke was conducting particle experiments.
Then when it came to other experiments, other people began to clamor.
"Look, look! What is an experiment? This is an experiment!"
"That's right! This kind of experiment that proves that light is a wave is the real truth!"
There were also many students who supported the light wave theory, and students from both sides began to quarrel.
"What bullshit theory? Don't you have eyes? Look at that obvious wavelength!"
"Fuck you, such an obvious particle phenomenon is why you tell me it's a wave?"
"So you are a fish-man school, because your IQ is the same as a fish-man!"
"If we are the same as fishmen, you are the same as fishmen's toes!"
"Light is a particle!"
"Light is a wave!"
When Lin Ke was conducting experiments and giving lectures, the two sides began to bicker with each other.
Of course, as a professional, it is easy to quarrel while listening.
However, their quarrel did not affect Lin Ke's speech because there was a corresponding isolation circle.
Although Lin Ke could also guess from the expressions and mouth patterns of the audience below what they were arguing about.
Ever since, as the lecture and experiment progressed, Lin Ke slowly said the following words:
"...So, at present, there are two theories headed by Mr. Off and Mr. Thomas, namely 'light is a particle' or 'light is a wave'."
Lin Ke has introduced the entire history of the debate about light.
Physics, chemistry, biology, mathematics, engineering, etc. The history of the struggle for natural science and engineering theories has a very typical feature.
What characteristics?
purely!
You said light is a particle?
Well, I must prove that the light is a wave!
I will use all my ingenuity to integrate what I have learned throughout my life, and then defeat you in theory!
You said that 1+1 is equal to 3 under general mathematical conditions, then I will show you the facts and tell you that it is equal to 2!
In mathematics, what is right is right and what is wrong is wrong. It is not as messy as literature, where nothing is right or wrong.
And it is different from political history.
A lot of history is always measured by interests.
If it were politics, perhaps scientists would not use their ingenuity, but their connections, tactics and fists to make their opponents surrender.
But in science, one plus one equals two. Even if you hold the knife to your neck, it still equals two.
Blue Star revolves around the sun. Even if you kill all the opponents of geocentrism, the orbital relationship between Blue Star and the sun will not change.
Not to mention killing all opponents of the theory, even if we kill all life, it may be difficult to change the physical laws of the Blue Star and the Sun.
So, this is the charm of scientific history.
This also makes the history of science not so treacherous and complicated, but rather pure and equally fascinating.
Lin Ke is also fascinated by the history of science, whether it is from past lives or Nassenger's.
Just like Nassenger.
Off and Thomas can obviously use their fists to resolve the issue of who is right and who is wrong, just like most humanistic history.
Whoever is strong can confuse right and wrong and call a deer a horse!
But they chose to use the simplest and most difficult way.
That is to prove the correctness of one's own theory, to refute the opponent's method, and to convince the opponent to lose.
Similarly, even if they lose in this process, they will be convinced and learn with humility.
Because they know that they lose not because the other party changed the rules, but because the other party discovered the rules through research and experiments.
Such scientists are also respected.
Of course, if Lin Ke could establish a promotion system for associate professors, professors, and faculty members...
If there is a conflict of interests, Ao Fu and Thomas might have their brains knocked out.
Anyway, it's okay to punch out the brain, and the elemental body won't die, but it just doesn't look good.
Or Lin Ke created a system, and every person who wanted to be promoted to an academician had to bring two cigarettes and two bottles of wine to see him.
This is the purity of scientific research.
Purity is pure research, just like two people competing for victory in a battle of glory and glory. It is pure when there is no conflict of interests.
But if I tell you who the opponent's son is, or how much money you can get if you lose to the opponent, what position you will be promoted to, what disease you will cure, etc.
Then you don’t necessarily want to win, because your winning or losing is beyond the rules of the game and uses off-field rules.
So this is because Lin Ke didn't create any nonsense scientific research promotion system.
At this time, Lin Ke finally began to talk about his theory of duality:
"So, classmates and teachers, when you heard the news, what did you think about?"
Lin Ke looked at all the viewers, then paused and continued:
"When you were watching the experiment, did you go through it in your head and feel that a certain experiment was more in line with the logic you thought it was? It was more in line with the theory you thought it was?"
"In this case, some students will try to think about the logic of another theory, but in the end they will join their own theory without hesitation?"
"And this isn't the problem?"
Lin Ke's words silenced the voices below.
This...is this the problem?
Some teachers and students were confused, and some looked astonished.
"Truth needs to be proven or falsified."
Lin Ke looked around the audience and spoke word by word with a firm and powerful voice:
"As [scholars], when you heard about these experiments, did you try the experiments? Did you try to think of new proof methods?"
"My teacher taught me when I was promoted to the fifteenth level. This has also benefited me throughout my life."
"He asked me: Are you always listening to others say how to get promoted to level 15, how to get promoted is good for you..."
"Then have you ever thought about putting it into practice? What others say, even if it is said by Emperor Wu Mian, even if it is said by Andrew, must it be right?"
"You have not practiced it. Are you really sure that the doctrine you support is correct?"
