The villainous young lady is actually a scientific research genius!

2:30 PM, Physics Lab.

Sunlight streamed in through the windows, illuminating the rows of lab benches.

Shen Yi stood in front of the first row of experimental tables, arms crossed, a confident smile on his lips.

Behind him, five or six boys from the physics competition group were whispering among themselves.

"Brother Shen is going to show Lu Zhaozhao what a real physics genius is today."

"Exactly, what's the use of being good at math? Physics requires hands-on experiments."

"Just wait and see her make a fool of herself."

Zhou Mingyuan stood on the podium, holding a stack of test papers in his hand.

"Quiet."

He spoke, his voice not loud, but the laboratory fell silent instantly.

"Today's diagnostic test was a comprehensive question."

Zhou Mingyuan paused.

"It combines electromagnetic theory and optical interference experiments, and its difficulty level is close to that of the national league."

As he spoke, he began distributing the test papers.

Shen Yi received the test paper and quickly glanced at the questions.

[An improved version of Young's double-slit interference experiment.]

[Under the given equipment conditions, measure the wavelength of monochromatic light and analyze the sources of error.]

[The difficulty level is indeed quite high, but I've done similar problems before.]

[As long as we follow the standard procedures and proceed steadily, it can definitely be completed within two hours.]

He raised his head and glanced at Lu Zhaozhao.

Lu Zhaozhao sat in the last row, her exam paper laid flat on the table.

She kept her head down, her gaze lingering on the question for less than ten seconds.

Then, she picked up a pen and began to write on the draft paper.

Shen Yi frowned.

Doesn't she check the equipment list first?

[Shouldn't we design the experimental procedures first?]

[Shall we start calculating right away?]

He looked away, stopped thinking about it, and turned to walk towards the lab table.

On the lab table was a simple set of optical equipment: a sodium lamp, two glass slides, a ruler, and several stands.

Shen Yi took a deep breath and began to build the optical path according to the standard procedure.

His movements were skillful, and he strictly followed the methods he had learned during competition training.

Adjust the position of the light source.

Fix the double-slit glass plate.

Measure the distance to the screen.

Record the spacing of the interference fringes.

Ten minutes later, he completed the measurement of the first set of data.

But when he saw the numbers in the notebook, he frowned.

The error is a bit large.

Is the light source unstable, or is there a problem with the double-slit spacing measurement?

He gritted his teeth and decided to test it again.

At the other end of the laboratory, Lu Zhaozhao remained seated in her original position.

The draft paper in front of her was already covered with densely packed formulas.

Zhou Mingyuan walked over and took a curious look.

Then, he stood there, stunned.

At the very top of the draft paper was a simple note:

Phase modulation compensation method—using an auxiliary mirror to introduce a controllable phase difference to compensate for measurement deviations caused by the non-ideal monochromaticity of the light source.

Below is a complete set of theoretical derivations.

Based on the principle of light wave superposition, a mathematical model for two-beam interference is established.

The geometric optical path correction equation after introducing the mirror group.

A wavelength measurement formula considering second-order diffraction effects is derived.

Finally, a quantitative estimation method for systematic errors is presented.

Zhou Mingyuan's hands trembled slightly.

This line of thinking...

[This is strikingly similar to the MIT paper I saw in Physical Review Letters last month!]

However, her derivation is simpler and more suitable for practical application!

[No one in China has applied this method in teaching experiments yet!]

He raised his head and looked at Lu Zhaozhao.

Lu Zhaozhao kept her head down, her pen moving rapidly across the paper.

Zhou Mingyuan swallowed hard, not daring to disturb her, and quietly retreated to the side.

Five minutes later, Lu Zhaozhao put down her pen.

She stood up and walked towards the lab table.

Shen Yi was sweating profusely over the outliers in the third set of data when he caught a glimpse of Lu Zhaozhao approaching, and a sense of unease welled up inside him.

[She's already started experimenting so quickly?]

"Impossible, she must have been doing something reckless."

Lu Zhaozhao walked to the empty lab bench and glanced at the equipment list.

Then, she reached out and picked up two pieces of glass, and then rummaged through a nearby storage box and pulled out a small mirror.

Shen Yi was taken aback.

【Mirror?】

What does she need a mirror for?

This problem doesn't require a mirror at all!

The thought had barely crossed his mind when he saw Lu Zhaozhao begin to build the light path.

Her movements were slow, but every step was incredibly precise.

Fix the mirror to the side of the double-slit glass and adjust the angle.

Use a ruler to measure the distance from the mirror to the screen and record the data.

Turn on the sodium lamp and observe the interference fringes.

The whole process was smooth and seamless.

Ten minutes later, she put down her pen and wrote down the final result in her notebook.

Then, she picked up her notebook and walked to the podium.

"Teacher Zhou."

She spoke, her voice calm.

"I'm done."

Zhou Mingyuan took the notebook and looked down at it.

At first glance, he saw a number:

[λ=589.3nm]

His eyes widened so much that he almost dropped the notebook.

This is... the standard wavelength of sodium D-rays!

The theoretical value is 589.3nm!

Her measurements were accurate to one decimal place!

With this rudimentary set of equipment, a measurement accuracy of 0.1 nm can be achieved...

This is already at a professional level of experimental skill!

He opened the notebook and saw the detailed experimental steps and data processing procedures inside.

Application of phase compensation method.

Geometric correction of the mirror assembly.

Quantitative analysis of systematic errors.

Every step was perfect.

Zhou Mingyuan's hands trembled even more violently.

This is not an experiment that high school students could do!

This is...this is a research topic at the graduate level!

No, they're even better than graduate students!

He raised his head and looked at Lu Zhaozhao.

Lu Zhaozhao stood in front of the podium, her expression still calm.

"Teacher, I'm leaving now."

After she finished speaking, she turned and walked towards the door.

Zhou Mingyuan opened his mouth, wanting to say something, but found that he had no idea what to say.

He could only watch helplessly as Lu Zhaozhao walked out of the laboratory.

The laboratory was completely silent.

Everyone stopped what they were doing and stared blankly at the doorway.

"No...she's already gone?" someone muttered quietly.

"Twenty-five minutes...she's only been doing it for twenty-five minutes, right?"

"I haven't even finished the first step..."

Shen Yi stood in front of the lab bench, the ruler in his hand falling to the ground with a crisp sound.

He looked at the string of data full of errors in his notebook, and then at the almost perfect theoretical value that Zhou Mingyuan had just written on the blackboard.

He was overwhelmed by a feeling of "Why did Heaven create both Zhou Yu and Zhuge Liang?"

She only took twenty-five minutes.

The method she used was something I'd never even heard of before.

Is this... the difference between geniuses and ordinary people?

He slumped into the chair.

Zhou Mingyuan stood on the podium, unable to come back to his senses for a long time.

After a long while, he took a deep breath and looked at the students in the laboratory.

"Today's test..."

He paused.

"This concludes the article."

After saying that, he picked up Lu Zhaozhao's notebook and quickly walked out of the laboratory.

He's going to find the principal.

He was going to find Yan Zheng.

He wants to tell everyone—

Lu Zhaozhao is from our physics competition group!

……

Meanwhile, Beijing University.

A young man in a postal uniform rode his bicycle through several streets and stopped in front of the office building of the Physics Department at Kyoto University.

He pulled a letter out of the mailbag and looked at the address.

"Professor Gu Chengyuan, please accept this."

He pushed open the building door, went up to the third floor, and knocked on the door of the office at the end of the corridor.

"Please come in."

The young man pushed open the door and placed the letter on the desk.

"Professor Gu, your letter."

Gu Chengyuan looked up and took the letter.

He glanced at the address on the envelope and frowned slightly.

[Beijing No.1 High School?]

Who will write to me from middle school?

He opened the envelope with a puzzled look and took out the letter inside.
