Head of Teaching at Hogwarts

Although this matter also involved Russell, when Professor McGonagall looked at Hermione and received her nod in agreement, she still smiled from the bottom of her heart.

Hermione was her favorite of all the students at Hogwarts, perhaps because she always felt that Hermione in school looked a lot like her as a child.

The same love of learning, the same feeling of being a bit of a “know-it-all”.

"Okay, even so, you should keep your voice down." Professor McGonagall said with a smile, then turned to Hermione, looked at the parchment in her hand, and asked: "Is this your thesis?"

"Yes, Professor McGonagall."

Professor McGonagall picked up the parchment and read it quickly. Then she realized that she could not understand a paper written by a second-year wizard.

I can't even understand the title.

What is "some minor improvements based on Newton's third law of motion to improve the levitation spell so that it can make the wizard float and fly"?

Is Newton one of the latest wizards to emerge?Why haven’t I heard of Newton’s third law of motion?

Despite this, Professor McGonagall still maintained the dignity that a professor should have. He did not ask questions, but looked at them patiently.

Fortunately, although Hermione's paper is short, it provides a very detailed explanation of the various concepts used in it, and the various derivation processes are also very detailed.

Professor McGonagall quickly learned what Newton's third law was. It was a theory put forward by a Muggle scientist. It roughly meant that the effect of force was relative. It was not difficult for anyone with life experience to understand.

But does such a simple truth still need to be called a "law"?Professor McGonagall expressed doubts that in her mind, what could be called "laws" should be some very important laws in the magical world.

Similar to the fact that transfiguration cannot produce food, only principles involving the essence of magic can be called laws.

Besides, how could a Muggle's theory be related to wizard's magic?Besides, using the levitation spell to make the wizard float himself is obviously against the basic principle of the levitation spell.

Professor McGonagall couldn't help but frowned.

She felt that Hermione, a talented student with great promise, was being taught badly by Russell, and had even forgotten the most basic theories in the first-year spells textbook.

This made her even more dissatisfied at the moment when she had already complained about Russell replacing Dumbledore as principal.

She had decided that after reading this paper, she would go to Russell's office and severely criticize the new principal who had conspired to replace Dumbledore.

Then, Professor McGonagall continued to read with this skeptical attitude. As she watched, her inner doubts became deeper and deeper. By the end, she had begun to doubt herself.

"Why, it seems that the more I read this paper, the more sense it makes." Professor McGonagall felt a little weird.

The essence of the levitating spell is that the wizard uses magic power to lift objects, which is why the levitating spell cannot make the wizard levitate himself.

However, according to Newton's third law "forces act reciprocally", as long as the floating spell is used on the earth, the earth will give the user a reaction force, and then the user will float based on this reaction force.

Professor McGonagall felt that she could not fault this paper logically, and was almost convinced by this second-year paper, which was less than two pages long.

"No! This definitely violates the basic laws of magic. There must be something wrong!" Professor McGonagall still had the final insistence in her heart.

But she couldn't find the loopholes in this paper, which made Professor McGonagall, who always liked to be more serious, feel extremely uncomfortable and entangled.

But soon she figured out how to solve this seemingly thorny problem—that is, to use hard facts to crush the lie.

Anyway, the conclusion of this paper is that "using a levitating spell targeting the earth will cause the wizard to levitate himself." Then you only need to try it once to prove the absurdity of this paper!

Facts don't lie!

Professor McGonagall regained her confidence again.

She didn't go to any hidden place to use the levitation spell. After all, it was just a levitation spell, the first spell a first-year wizard had to learn. There was no risk factor.

Professor McGonagall took out her wand and pointed it at the floor of the Gryffindor lounge. She waved the wand gently, accompanied by the words "Wingardium Leviosa".

Professor McGonagall's originally calm face suddenly showed an incredible expression, and she flew up!

To be precise, it is floating, slowly getting away from the ground, first a little gap, then an inch, two inches...one foot...two feet...

When Professor McGonagall had risen to a height of three feet above the ground, she stopped increasing the magic input, and her height stabilized at just three feet.

Then as her magic slowly dwindled, she dropped to the ground again.

How can this be?This goes against the most basic laws of the floating spell!

But the facts don't lie!

In the face of the hard facts, Professor McGonagall had to believe that a law he had believed in for nearly 50 years had been broken, and all of this came from the second-year wizard in front of him.

No, it shouldn't come from this second-year wizard, but from Russell. It must be him who guided Hermione to discover the great and incredible other side of the basic magic of the Levitation Charm.

"Miss Granger, did you discover this on your own?"

"That's true on the surface, but in fact I made this discovery based on Professor Russell's guidance in the book!" Hermione whispered.

Sure enough, Professor McGonagall nodded and said excitedly: "What an incredible discovery. This may be one of the greatest discoveries in the wizarding world in the past half century.

Simple, beautiful, harmonious and extremely practical, I will help you publish this paper. Maybe you can get a medal of the Knights of Merlin with this paper!

Now, I think we need to go meet Professor Russell! "
