As the person with the lowest education level present, Samuel Coleman was embarrassed from the first minute after the professor Tiantuan arrived, serving tea and water, and asking about his health.

Don't even dare to call yourself a scholar.

In addition to listening to the opinions of the professors and the art of swearing without swearing, most of the time is spent counting the few hairs on the top of my forehead.

The scariest thing was more than that. When his tutor Sir Daniel asked him to talk about his thoughts, Coleman wished he could evaporate under the "friendly" gaze of the professors.

He even felt that breathing was a mistake at this moment, until... Tu Fu pushed the door open.

Mr. Coleman's eyes flashed with a strong brilliance.

Finally, the savior came.

He can't compare to these academic leaders here, but he is more than enough compared to a kid who hasn't gone to college yet.

"...Mr. Coleman."

After Tufu came in, he called the titles of the professors one by one, and finally greeted Mr. Coleman.

The other party did not take offense at the address of "Sir", and Mr. Coleman showed a relieved smile.

Gently patted the student on the shoulder, "Come on, hurry up, explain your conjecture about the composition of light to the professors, even if you are wrong, no one will blame you."

"Yes, boy, talk about what you think, it's quite an interesting question."

The old Sir Daniel held a pipe and looked at the young student with interest. The professors from the Seven Schools Alliance sat in a circle and looked at themselves.

It's very similar... the way you are doing your graduation defense in front of your tutors.

Before coming here, Tu Fu heard Mr. Layton talk about the identities of the professors.

The top scholars in the field of natural sciences from all over the North Continent have come to this little-known academy, and one of the purposes is to have a "friendly exchange" with the person who raised this question.

But in fact, including Sir Daniel, they didn't have much hope for this child, but more of an interest in his thinking mode.

I just want to check with my own eyes to determine whether I have the potential to be a student under the name of income.

Similarly, for Tu Fu, there is no better opportunity to show his self-worth than this.

"Gentlemen, in fact, in my opinion, just particles or waves are a complex problem. If even the professors can't explain it, it is obviously inappropriate for me to draw any conclusions."

Tu Fu's words were very tactful, he paused for a moment before smiling and said, "Why not do a reference optical experiment to determine whether light is composed of waves or particles."

Tu Fu did not directly put forward the conclusion of the wave-particle war that lasted for three hundred years - "wave-particle duality".

For this seemingly simple answer, almost every student who has attended high school physics knows some required knowledge points.

Black body radiation, photoelectric effect, energy quantum, thermal radiation...

That war in the physics world experienced Newton, Hooke, Huygens, Planck, Bohr, Einstein, Heisenberg, Schrödinger... almost all celebrities in the history of physics participated in the most thrilling war.

The "light-particle dual pictogram" from the macrocosm to the microcosm, from quantum mechanics to matrix mechanics, cannot be explained in a few simple words, nor can it be explained clearly by current technology.

Instead of putting forward the conclusion of the development across the ages, it is better to throw out an early concept of wave-particle warfare, I believe this is enough to shock the gentlemen.

"An experiment?"

Professor Edmund, the head of the department at the University of Göttinghagen, touched his chin, "Tell me specifically, no matter what complex experimental device you need, Columbia University can meet your needs."

"No, this experiment only needs three simple components." Tu Fu stretched out three fingers, "a light source, a piece of cardboard with two slits, and a screen for receiving the projection of the light source."

"What are you going to do?" The old knight felt that this expedition was getting more and more interesting.

Tu Fu raised his head and said loudly: "Put the light source in front of the cardboard with double slits, and see the final shape of the light projected on the screen."

After a brief silence in the office, the scholar from the Landis Royal Society couldn't help but admire, "What a genius idea."

All the people present here are experts in the field of natural sciences. When they heard this fantastic idea, they immediately understood the principle of this simple experiment.

If the light is really a particle, then it must simply be emitted directly forward, facing the double slits left by the cardboard, and the particles randomly pass through the left or right slit, and only two bright spots will appear on the screen.

If light is a kind of wave, similar to the composition of water waves, then the light rays will undoubtedly interfere with each other after passing through the double slits, resulting in multiple bright and different stripes.

After Tu Fu recounted the principle, this wonderful idea immediately made Sir Daniel shout excitedly: "Samuel, take me to the laboratory immediately."

Poor Mr. Coleman, after hearing the conjecture put forward by Tu Fu, the last bit of pride in his heart was crushed to pieces. His two empty eyes began to glow, as if he was about to glimpse the door of truth.

"yes."

Hearing the mentor's call, Coleman, who was over half a century old, quickly led a group of big figures in the academic world to leave the office in a hurry.

"professor!"

"Where are you going?"

Those professor assistants waiting outside the door saw this scene.

This group of old fellows, whose combined age was nearly a thousand years old, didn't have the slightest elegance of the past, and ran out scramblingly, and couldn't even hear the shouts of the assistants.

I'm afraid that if I delay for a while, I will miss the upcoming historic scene.

Even though it was just a primary education college with crude experimental equipment, fortunately, the equipment needed for this experiment were very common supplies.

Standing in the laboratory and receiving the searchlight from Mr. Coleman, Tu Fu started to cut out a double-slit cardboard, and there was a white curtain in front of him.

They are all simple experimental devices, and there is no difficulty in operating them.

But the difference is that there are more than a dozen pairs of eyes watching his every move, and it seems that there is a tacit understanding. Every professor in the Seven Schools Alliance is concentrating and holding their breath for a short time to maintain the tranquility in the laboratory.

"it has started."

In this sacred experimental environment, Tu Fu set up the experimental devices one by one, and first turned on the wrapped gas lamp with a "click".

The only string of orange-yellow straight beams of light penetrated the air, and it was this seemingly insignificant beam of light that ignited the fuse of a war of hundreds of waves across two time-spaces.

Perhaps after today's experiment is over, the light-particle-versus-wave war will continue.

After hundreds of years, the basic technology will improve again, and people will improve this experiment again and again, and put forward more possibilities to refute and overthrow the current answer that is not so correct.

But now, this beam of light symbolizing truth, chosen by history, passed through the double-slit cardboard steadily and steadily, and finally fell on the white screen like water waves.

Streaks appear.

After passing through the cardboard, the light forms light and dark interference fringes.

"Buzz!"

It was the scholar, the professor and the old jazz who gave out this admiration, and everyone was immersed in a huge shock.

The God of Order, who is in charge of truth, seems to have made a verdict at this moment.

God guides the world in the right direction.

The choice of history is the volatility faction.

"This is an experiment that is destined to remain in the annals of history." The old jazz, who supported the wave school, burst into tears. He was trembling with excitement, "What name are you going to give it?"

Tu Fu nodded seriously, silently apologized to the great Mr. Thomas Young in his heart, and then slowly said: "There is no more suitable name than 'double-slit interference experiment'."

June 25, 1492.

On this unusual day, people will always remember that the first wave-particle war ended with the great "double-slit experiment" put forward by the young man Tuf Capet, which temporarily stopped the war.

PS: I would like to recommend this book to everyone, "I Use Science to Explain Weird Powers and Chaos Gods", the author of this book is really well written.
