In This Hogwarts Without a Savior

  Chapter 47 47. Gravity

   "Wingardim Leviosa."

  The desk in front of Jon flew up under the influence of the spell, but it was only 20 to 30 centimeters above the ground, and there was no way to go higher.

   Neville, who was studying the memory ball sent by his grandma while gnawing on an apple, looked at Jon with a look of lovelessness.

"It's been a month, a whole month! On average, you have to practice this spell more than a hundred times every day! Every night I dream of the sound of the floating spell in my ears. You are really successful enough, Jon! Last time Professor Flitwick has already said, at least your level of levitation spells has reached the standard of most adult wizards, what is lacking now is that your magic power has not yet grown, so you really don't need to practice any more!"

  Jon was still looking at the floating desk in front of him thoughtfully.

"That's right, Professor Flitwick said that my skills in the Levitation Curse are high enough, and the rest can only rely on time to accumulate my own magic power and experience, but why is the biggest effect I can achieve now? ?”

"That's all?" Neville stared at the dead fish eyes, "What you flew up with the magic spell was not feathers, parchment, or textbooks, but a desk! Now there are a few people in this carriage besides the professor. Can it be done to this extent?"

   "It's not a question of whether other people can do it, but the Levitating Spell itself feels very problematic." Jon frowned.

  Neville bit the crunchy apple, looked at Jon who finally stopped using the Levitating Charm, and was also happy to chat with him a few more words to make his ears less tormented.

   "What's wrong with the Levitation spell?"

   "The role it can play is a little too small."

  Jon was thinking, subconsciously turning the wand with his fingertips. In his previous life, he liked to turn the pen when solving problems, and now this habit has been brought into this world by him.

  "Even Professor Flitwick, the levitating spell he used couldn't make too heavy objects fly. This was not only because of the limitations of his magic power and will, but because the spell itself couldn't exert this effect."

  Neville could no longer understand what Jon was saying, so he could only nod his head in agreement, repeating "Yes, that's right, that's it" three times in a row.

"The levitation spell has been created for such a long time, and many wizards have tried to improve and innovate it in history. Now what we have learned is the limit it can achieve. Magic controls objects. The limit of flight."

"One is the limit of the floating spell, and the other is that the spell cannot be released on wizards. The combination of these two unsolvable problems has led to the fact that wizards still rely on broomsticks and magic carpets to conquer the sky. An ancient magical tool that has been in use since."

   "But since broomsticks and magic carpets can fly so high, why does the floating spell have a limit?"

   "I still have the limit to eat apples, two are enough." Neville threw a cleaned apple towards Jon, "Don't think about it yet, try it, it's very sweet."

  Jon, who was thinking hard, of course didn't notice the apple flying towards him, and the apple hit him on the head without any accident.

"boom!"

   "Ah! I'm sorry, I didn't mean to, I thought you could catch it."

  Neville hurriedly apologized, Jon was taken aback after being hit, and then looked at the apple that had fallen to the ground with a strange expression.

   "Neville, why do you think the apple fell on me?"

   Neville was stunned by Jon's question, and he looked at Jon even more nervously.

   "Are you okay? Are you dizzy? How about I take you to see Professor Slughorn?"

   "Because the apple will fall."

  Jon stared at the apple brightly, he ignored Nawei, but said the answer on his own.

   "My thoughts have always been limited! This world not only has magic, but also science!"

  "When you threw it out, you provided it with an upward force, but in fact there is still a downward force pulling it back to the ground!"

   Neville had already grabbed Jon's arm.

   "Let's go, hurry up, before you do anything stupid, let's let the professor see if you can still be saved!"

  Jon slapped his hand off with a black face.

   "I wasn't fooled by the apple! I don't need the professor to heal me. I'm thinking about the problem seriously. Have you ever thought about what is going on in your mind when you cast the levitating spell?"

   Seeing that Jon didn't seem to be lying, and other than talking nonsense, his behavior was indeed quite normal, Neville replied hesitantly.

   "It's just like what Professor Flitwick taught us in class, unwaveringly believe that the target the wand is aiming at can fly up, and then cast a spell and swing the wand."

"Knowing it but not knowing why, this has always been a characteristic of magic." Jon's voice was calm, but he could see that he was extremely emotional, "It's like turning matches into needles." At that time, professors would not teach us what molecular structure changes inside an object when it changes from wood to metal."

"The same is true for the floating spell! Professor Flitwick just told us to firmly think that we can make feathers fly, but he didn't tell us what kind of principle is needed to do this, and then the floating spell we used appeared It came up with the simplest and most direct way of expression - forming an upward force on the object itself, saying that it is flying, but in fact it is the power of magic that holds it up!"

  "Magic is the intervention of the rules, the wizard puts forward the idea of ​​changing, and how to change is determined by the magic itself!"

   "But if we take the initiative to choose when casting a spell, to specify how the magic will interfere with the rules?"

  Neville couldn't understand what Jon was saying at all, but his mouth was open. Although he didn't understand, he could feel that his roommate had obviously thought of something extraordinary!

   "Do you know why the apple fell on my head?" Jon asked this seemingly silly question again.

  Neville also replied with a silly answer: "Because I just threw it at your head."

  "A Muggle who was also hit in the head by an apple more than three hundred years ago was also thinking about this question, but he came up with the answer himself."

   There was a smile on Jon's face. It was the smile of standing on the shoulders of giants, looking down at the wizards who had no exploration of the rules of the world.

  “There is a force in the land we live in. This force pulls all objects on the ground, ocean and even the sky. The Muggle named Isaac Newton called this force—gravity!”
