From top student in college to scientific research powerhouse

Chapter 48: If I let you see it, is it still considered invisible?

Institute of Optics, Laboratory for Core Optical Materials.

Sun Wen was the only one left in the huge laboratory. She carefully examined the materials on the table, her glasses on, and occasionally shone her flashlight around.

Zhang Minghao saw this scene as soon as he entered and immediately asked, "Professor Sun, did you notice anything?"

"Come on!"

Sun Wen waved excitedly, pointing to the materials on the table, and said, "If you hadn't told me, I would have really thought we had failed."

"Upon closer inspection, it's quite unusual!"

She shone her flashlight on the material and said, "Look at the light transmittance. It's very obvious, extremely high."

"It hasn't been tested yet, but you can tell at a glance that it's not much worse than tempered glass."

"Also, look at the radio light; it doesn't just scatter directly, which means that the light transmission inside the material is different from the conventional method."

"The surface is very smooth, so the light scattering effect should be reduced."

"Look at it from the side..."

As Sun Wen spoke, she half-squatted down and looked at the material along the tabletop, "4.3 millimeters thick, smooth construction, but the wall line appears as an arc..."

She stood up and excitedly concluded, "There's hope!"

Zhang Minghao also felt hopeful, mainly because of his confidence in the design. He believed that as long as there were no major problems in the manufacturing process, the invisibility would definitely have some effect.

"Let's try making it into a ball, and wait until tomorrow?"

Sun Wen immediately realized what was happening. She glanced at the time and turned to leave, saying, "No need!"

"Deng should still be at get off work, I'll go find him!"

Before long, a dispute broke out in the hallway: "Professor Sun, I'm off work!"

"Master Deng, please make it for us, we can't wait any longer."

"Can't it be tomorrow?"

"I'm in a hurry, just make a small ball..."

Sun Wen dragged Deng Jiashan over, and Deng Jiashan was very reluctant when he entered the door.

Zhang Minghao nodded and greeted him.

Sun Wen gave a brief introduction, and then the topic turned to the issue of material shaping. "Master Deng, just help me make the material into a ball, just make a small ball first."

"This is invisibility material. Once it's finished, you won't be able to see it. Isn't that interesting..."

"We really can't wait any longer!"

Deng Jiashan listened expressionlessly, not believing a word of it.

He had heard from others that what Sun Wen made looked like a 'tablecloth,' and that the 'sucker sponsor' she was researching was a doctoral student.

PhD student, Zhang Minghao?
"It's right in front of me..."

Deng Jiashan's gaze towards Zhang Minghao changed.

He shook his head, reached out and touched the edge of the material, and made a simple judgment: "This material is malleable, so it should be fine to mold it into a sphere."

"Let's do a test first..."

He then cut off a small corner with a knife and began using the equipment to perform basic testing.

This includes the material's surface smoothness, tensile strength, heat resistance, changes with increasing temperature, changes in light transmittance after stretching, and so on.

Sun Wen also got busy.

After all the tests were completed, Deng Jiashan took detailed measurements. The final steps involved designing, cutting, and then using machines to perform physical stretching.

After completing the entire process, we arrived at the final shaping stage.

Shaping is not about turning the material itself into a sphere, but rather about laying the material on a spherical mold and then filling it with shaping material.

With solid material inside supporting it, the invisible material on the outside can be fixed into a spherical shape.

Once the shaping was complete, a perfectly round sphere was created, with no other traces visible on the surface, as if it were formed from a single piece.

The sphere is about 15 centimeters in diameter, much smaller than a soccer ball.

The sphere is supported by a base and a bracket, which is connected to the internal molding material.

Under the light, the outline of a sphere can be vaguely seen.

"Sigh~~~"

Deng Jiashan held the sphere up to his eyes and gasped in astonishment, "It really is invisible!"

He was looking at the sphere right in front of his eyes.

From his perspective, his gaze pierced directly through the sphere, revealing Sun Wen, whom he shouldn't have been able to see.

Sun Wen also saw Deng Jiashan's somewhat blurry face through the sphere, and she urged impatiently, "Put it on the table, put it on the table!"

"Let me see."

Deng Jiashan placed the ball on the table.

The two people standing next to it noticed the sphere's visual penetration characteristics even more clearly. When looking directly at the sphere, they could see the wood grain on the table behind it.

"It really does have a visual penetration effect!"

"Invisible!"

"If it weren't for this outer outline, you really couldn't see it at all..."

"Vision is still a bit blurry, which is very noticeable when compared to the light next to it, but you can't notice it unless you pay close attention."

"If it were daytime, and not under artificial light, the difference in lighting would be minimal, right?"

Zhang Minghao stood some distance away, then suddenly said, "Come over here!"

Sun Wen and Deng Jiashan immediately went over.

Zhang Minghao's position is more than four meters away from the sphere. When viewed from a distance, the visual effect caused by light scattering will be greatly reduced.

In other words, from his position, he couldn't see the outline of the sphere; all he could see was a stand on the table.

Sun Wen and Deng Jiashan were immediately stunned.

From this position, it really looks like an empty support frame; there's nothing on it.

"hiss……"

Deng Jiashan gasped again.

Zhang Minghao smiled happily, "Professor Sun, is it possible to get funding for this?"

"Yes, absolutely!"

Sun Wen's voice was filled with excitement, "No wonder you said you wanted to apply for a patent!"

"Those people even said we made a tablecloth, which really annoyed me, so I put it on the table and made them so envious!"

……

When Deng Jiashan discovered that the material could indeed be used to make an invisible sphere, he was filled with enthusiasm. At Zhang Minghao's request, he helped make a similar sphere, and watched it for a long time before reluctantly finishing it and going home.

So the next morning, there was an invisible ball on Zhang Minghao's desk.

He just kept staring at it.

It's very interesting that you can see through the sphere to the back of it, especially since the sphere itself was designed by him.

What a sense of accomplishment!

Chen Lanjun brought breakfast to the workroom. She had just sat down and was about to enjoy her meal when she noticed Zhang Minghao staring at the table, his eyes unwavering.

"looking at what?"

She looked over in confusion and then noticed that there seemed to be a spherical object on the stand on the table.

The spherical object seemed to exist, yet it also seemed not to, because she could see the mouse directly in front of her.

"Ok?"

She jumped up and pointed at the things on the table in surprise, "Is this the 'spherical invisibility device'?"

He immediately moved closer.

Only after getting closer to look did I realize that there was a sphere on the support.

"It's truly an invisible ball!"

"This effect is amazing! I didn't even notice it..."

She was completely stunned.

Zhang Minghao felt a little smug. He smiled and said, "I told you, the invisibility effect is very good, but it feels even better than I expected."

Just then, Liao Shuyan and Xu Chao arrived together.

They were discussing experimental issues when they came in and Chen Shuai asked them about the analysis data results, specifically the correlation between the bismuth telluride substrate and the experimental products.

Once the correlation is analyzed, experiments can be conducted to verify it.

As they walked into the workshop, they noticed Zhang Minghao and Chen Lanjun's heads huddled together.

Xu Chao even coughed lightly as a reminder.

Liao Shuyan noticed something unusual and immediately went over. As he got closer, he exclaimed in surprise, "There's something there!"

He reacted faster than Chen Lanjun, "A translucent sphere! Is it the one we were calculating?!"

Xu Chao caught up in a few steps, also staring intently at the invisible sphere. Suddenly, he asked, "Zhang Minghao, what's the name of this sphere you designed?"

"A spherical stealth device?"

"What about it?"

"What do you mean?" Zhang Minghao asked, puzzled.

"That means the name of the research, the name of the entire project," Xu Chao said earnestly. "I need to write it down."

"When I write my resume for job hunting in the future, I can add a sentence like, 'I participated in the research and development calculation work of spherical stealth device during my doctoral studies.'"

"Instantly, the class was elevated!"

"clever!"

The same thing happened in Sun Wen's office on the first floor of the Institute of Optics.

Sun Wen also placed the invisible ball on the table.

"Dong, dong..."

Tan Yanming knocked on the door and came in, asking with concern, "Sun Wen, I heard you didn't go home yesterday?"

"Are you okay?"

He was really worried.

The police station said they spent hundreds of thousands of yuan on a tablecloth; you can imagine how the person involved felt.

Not going home for one night must have been a huge blow.

"Director Tan, thank you, I'm fine!" Sun Wen replied casually.

Tan Yanming was worried, but also a little curious. Looking around, he asked, "By the way, what about the invisibility device you made?"

Afraid of touching on Sun Wen's sore spot, he quickly added, "Let me see, maybe there's something interesting about it."

Sun Wen immediately laughed and said, "Director Tan, you already said it's an invisibility device. If you can see it, can it still be called invisibility?"

Tan Yanming chuckled. "Alright! You're right."

He shook his head and walked out.

He didn't care at all; what kind of invisibility device could actually make someone invisible?

Sun Wen was just joking. The fact that she can still joke shows that she's a normal person.

No sooner had Tan Yanming left than Wang Qingxin arrived.

Wang Qingxin also came to see Sun Wen. When he entered the room, he noticed that Sun Wen was staring at the table.

There's an empty support frame there...

"looking at what?"

Wang Qingxin walked over curiously, and only when he got closer did he vaguely notice the outline of a sphere on the support.

"What is that!" he exclaimed in surprise.

"A ball made of tablecloth!"

Sun Wen looked up, her face beaming, "Look at the ball we made out of a tablecloth, isn't it great?"

Wang Qingxin looked at it carefully, then took a few steps back and looked again, and couldn't help but gasp.

You can't see it from a few meters away!
Is that a tablecloth? Who spread this? This is a real invisibility device!
"Incredible, truly incredible!"

"this thing!"

"From a distance, you really can't see it, and you can't see it from any angle..."

Wang Qingxin looked around and stayed in the office for more than half an hour before coming out.

Upon reaching the office on the second floor, Tan Yanming immediately asked, "How is Sun Wen? Is she alright?"

"she?"

Wang Qingxin forcefully pulled at his lips, "She's wonderful, wonderful beyond compare!"

"The stealth device they built is amazing!"

"Invisibility device? She took it out? In the office?"

Tan Yanming asked in confusion, "Why didn't I see it?"

Wang Qingxin immediately raised his head, "You said it's an invisibility device, but if you can see it, is it still considered invisibility?"
