Hogwarts I have been guarding Azkaban for ten years

Soon, Browder was taking his first class.

In the third grade class, the entire classroom was full. If Professor Quirrell, the former Muggle Studies professor, saw this scene, he would probably burst into tears. Except during group activities, Quirrell never saw so many students. appear in a classroom at the same time.

Many of the students in the audience had strange faces. The only ones Browder knew were the Weasley twins. The red hair of the Weasley family was really eye-catching.

Looking at the extremely excited students below, a smile appeared on Browder's lips. Most students probably just want to play games, but you are too young.

"I know that many students come to my course just to play the game Mr. Harry Potter played, but it's a pity. As I said before, what I teach is not such a simple thing. I need you. What we learn more is [Magic] in the Muggle world, so our first lesson is about physics."

In the audience, many young wizards drooped their eyes in disappointment. Most of the light in the male students' eyes disappeared, but the light in the female students' eyes was still there.

They not only came to watch the game, but also came to admire Professor Browder's beauty in his prime.

"Many people may not have heard of this thing at all, and I can tell you the reason, because the cost-effectiveness of learning it is not high."

"Physics tells us the laws of object motion and reveals to us the mysteries of nature, but there are many things we can easily do with a wave of a magic wand."

"For example, the train you made when you were in school was an important achievement in physics."

When the train was mentioned, the little wizards below all had expressions of "So that's it." They now thought trains were physics.

"Trains are a means of transportation, but we wizards have brooms, which are faster than trains, so even if we learn these things, it is of no use."

The Weasley twins immediately raised their hands, and Browder randomly clicked on one.

George stood up: "So we don't need to learn physics at all, right? Let's take a look at the magical Muggle simulation toys!"

Browder smiled: "You said it very well, so five points will be deducted from Gryffindor."

"I said, what I want to teach you is the magic of the Muggle world. This will be a very long and difficult road. I know that many of you come here with a game mentality, so I Let me tell you, the days of study in the future will be very different from the life you imagined!"

Browder's face became serious, and the originally cheerful classroom gradually fell silent.

Everyone felt a pressure from this professor. This is the momentum of a person who wants to accomplish something seriously.

"The road to learning is at your feet. There is no limit to the sea of ​​learning. For easy entertainment, please go elsewhere. Don't come here for idleness. If there are still some of you who have unrealistic ideas and think that taking my class is just for fun. Game, then you can leave now."

Browder now has surprisingly many students, and it is easy to attack and defend. Now professors choose students instead of students choosing professors.

The students in the audience looked at each other in confusion, but no one chose to leave.

Just kidding, as long as they can play that simulated Muggle, they can even study History of Magic!

"Very good, it seems you have the awareness to receive education."

When Browder saw that not a single student left the classroom, he nodded with satisfaction. With a wave of his hands, the lights in the classroom immediately disappeared, the curtains closed by themselves, and the room immediately became dim.

The little wizards all looked at Browder with envy. This professor could actually cast spells without a wand!

This is something that none of the previous professors could do!

The girls' eyes sparkled again, Professor Browder was simply the perfect lover in their minds!

Browder's voice came from all directions: "The so-called physics is the principle of object movement. In the Muggle world, many things operate according to certain rules. We wizards and Muggles live in the same world. Some basic principles we Of course, we must also accept and understand it, so the first lesson we learn today is light.”

"First of all, let me ask you a question. What do you think the world looks like through the eyes of a blind person?"

The group of young wizards below look at me and I look at you. They feel that this question is very simple. A handsome and talented professor like Professor Browder should not ask such a simple question.

brush!A student from the Snake House raised his hand, and Browder gracefully asked him to stand up and speak.

"It must be black!"

"It is a good character to have the courage to answer questions, but unfortunately, the answer was wrong." Browder showed a regretful expression.

"Now everyone close your eyes. Tell me, what do you see?"

Everyone closed their eyes and saw darkness, so they loudly replied: "Black!"

"Very good, now what?" Browder cast a silver flashing spell and continued to ask.

The students hesitated now. They said sparsely and hesitantly: "Red...red?"

"Okay, you can open your eyes now," Browder put away the fluorescent flashing spell and asked the students to open their eyes.

"The red color you see is actually the color of the blood flowing in your body, so after you close your eyes, your world is still different from the world of the blind, because your eyes can still feel the light."

"Now, Mr. Weasley," Browder pointed at Fred, "now tell me, what color is behind you?"

A small ball of fluorescent light floated behind Fred. Fred looked confused. He didn't know what was behind it.

"That's right," Browder clapped his hands, "This is how blind people feel about the world. They don't know, it's nothingness. They feel nothing."

"You can't see the color behind you, and blind people can't see the scenery in front of you. Can you say that the color behind you is black? You can only say that it is nothingness."

"How we perceive the world is through light entering our eyes. Our eyes process all information, so we can see the world."

Browder's textbook-level introduction to physics and optics is perfect. Although many students still don't understand the significance of this, they always feel that they have learned useful knowledge, and a sense of satisfaction in acquiring knowledge arises spontaneously.

Browder used his own killer move: "So, our eyes determine what we see, and the light determines what our eyes can see. In this case, what we sometimes see may not necessarily It’s real.”

As Browder spoke, he blew forward gently, and bursts of mist suddenly spread throughout the classroom.

The students were all shocked. Professor Browder was so loud!

Then, the students' eyes flashed, all the fog disappeared, and the surrounding scene changed drastically!

Every student saw themselves standing on a grassland, with a cloudless sky and a dazzling fireball hanging on the blue cloth. There was no one around but themselves!

"What's going on? I learned how to change my appearance?"

"Oh my God! Professor, where did you apparate us to?"

"Hey! Calm down! I saw the grass moving but I didn't feel the wind. This must be fake...Walterfak? The wind is really blowing on my cheeks! We are here in the grassland!"

Just when all the students were in panic, Professor Browder's figure appeared in front of everyone, face to face.

"Wow! Professor Browder is so close to me!" a female student screamed.

Many girls boldly reached out to touch Browder, but they didn't touch anything. Their palms passed directly through Browder's body.

Damn!

"Don't panic, this is an illusion created by me using the refraction of light. Just now a student said there is no wind here, so I used a little bit of wind spell to bring you the most realistic experience."

"You are safe now, still in my classroom at Hogwarts, but what you see with your eyes is indeed another scene, which is the application of optics."

After Browder finished speaking, all the effects were removed. All the students felt a strong wind blowing, and the scenery in front of them turned into a white mist. When the fog dissipated, everything in front of them became the original classroom again. appearance.

Many students were still in disbelief. They were stunned and stretched out their hands to touch the table in front of them to confirm whether they had returned to the real world.

"Professor! I want to learn this!!!"

When they reacted, they all screamed.

What does it mean to learn this?

It means that you can conjure up whoever you want, and you can see whatever you want to see!

Ten thousand kinds of pranks that could be realized with the help of this spell appeared in the minds of the Weasley twins. For a moment, the whole classroom was boiling!

Satisfied, Browder opened all the curtains, making the classroom bright again.

"You want to learn, that's great, I will teach you this skill without reservation. By the way, this is the practical project for our final exam!"

what?

Everyone's enthusiasm disappeared instantly. Professor, are you too confident?

If I don’t show you my skills, you don’t know how much we have to offer, right?

Wizards are not fools, and such reductionist illusions are simply not something they can create.

Browder smiled softly: "I won't let you do something so difficult. You only need to do some simple illusions."

The students in the audience breathed a sigh of relief. They were almost scared to death just now.

"Okay, since we want to learn this illusion, we need to know the basic principles of light. First of all, we need to understand that there are several colors of light in nature..."

Browder turned around and officially started his first class.
