Chapter 168: Practice

"Let's start experimenting now!"

Wu Fan didn't give the students a chance to regret at all, and directly asked a student to pick up two stones of different weights nearby.

Everyone knew that they were pouting angrily and sullen, but there was no way, after all, they promised it themselves.

Wu Fan once taught them: "If you dig a pit yourself, you have to jump down with tears!"

"For the sake of fairness, the teacher will not operate this experiment, so you should choose one. ”

After the student picked up the two stones, Wu Fan smiled and made a gesture of please.

"Then come on, squad leader!"

I don't know who shouted, this proposal was immediately recognized by everyone, and everyone looked at Zhou Xuanwen, who had just become the squad leader yesterday, with a little prank in their eyes.

Zhou Xuanwen shook his head with a wry smile, and did not refuse, he stood up directly, took the two stones, held one in each hand, and straightened his arms horizontally.

"You can now see that both stones are the same height, and that one of them is the size of a fingernail, and the other is almost half a fist in size, and that their weight is very different. ”

"According to your thoughts, when these two stones fall at the same time, the heavier one must fall to the ground first, right?"

Wu Fan asked with a smile, and after seeing the students nodding, he immediately said, "Okay! What is the answer, we will soon find out!"

Then, he looked at Zhou Xuanwen, stretched out three fingers, and shouted at the same time: "Three!"

"Two!"

"One!"

"Let it go!"

As soon as the words fell, Zhou Xuanwen immediately let go of his hands, and the stone in his hand immediately fell straight to the ground.

"Bang!"

Two stones hit the ground, but only one sound sounded.

The students sitting on the side all stared at it with wide eyes and carefully, but were shocked to find that these two stones seemed to have landed at the same time.

What's going on?

Are we dazzled?

At this moment, many people begin to doubt themselves and are very puzzled by what they have witnessed!

There was silence.

"Tell me what you saw?" Wu Fan asked casually, pointing at a student.

The student hesitated for a moment, then replied, "Teacher...... I seem to ...... Seeing them land at the same time......"

"Teacher Jiang, what did you see again?"

Wu Fan suddenly turned around, walked up to Jiang Ruoyu and asked.

Jiang Ruoyu was also in shock, but she was not so obvious, after hearing Wu Fan's inquiry, she lowered her head, pursed her lips, seemed to be a little unwilling, and said: "This height is too low, maybe the time they landed is too close, causing us to mistakenly think that they fell at the same time, I suggest increasing the height and doing it again!"

"No problem, then do it again!" Wu Fan agreed very happily.

Even if no one asks for it, he will take the initiative to conduct another experiment in this way.

Many students agreed with Jiang's suggestion, and felt that it was because the height was too low that they could not distinguish between right and wrong, and some students were even inspired to suggest that the weight difference between the two stones should be increased a little more, so that the difference would be more obvious.

Wu Fan also smiled and nodded in agreement, but secretly said in his heart: "In the face of absolute science, no matter how much trouble you make, it will be useless!"

This result also seemed to stimulate Zhou Xuanwen, and before Wu Fan could say anything, he took the initiative to find the stone again.

It didn't take long for him to bring a stone about the size of his head, which looked to weigh tens of kilograms, and another stone, which he chose to cover with the size of his fingernail.

At the time when he was looking for stones

Wu Fan was not idle, and sent a few students to climb a big tree and cut down all the branches under it, leaving only the top branch and a trunk like a bare pole.

This is done to avoid being affected by the leaves when the stones fall.

This big tree is dozens of meters high, and it originally looked majestic and majestic, but after experiencing the 'poisonous hands' of Wu Fan and others, it became so weird.

Zhou Xuanwen didn't say a word, and climbed up with these two stones very quickly.

This action may be difficult for ordinary magicians, but in front of Zhou Xuanwen, who is about to become a general, it is easy to do and smooth.

In less than half an hour, they had already climbed to the top.

Wu Fan had an idea, in order to avoid that the stone covered by his fingernails was too small and everyone might not be able to see it clearly when it fell, he also deliberately exchanged a super large wooden basin from the system space, filled it with water and placed it under the big tree.

In this way, you don't need to look at the stones, just see if there is a splash at the same time, or whether the sound of entering the water is sounded at the same time.

After everything was ready, Wu Fan began to give orders as he had just done.

But the hearts of the people on the side were tugging, and they began to worry about whether the result would be satisfactory, which had not happened in the previous experiment.

Before, they all thought that they were going to see the teacher embarrassed......

"Let it go!"

With Wu Fan's order, two black shadows suddenly appeared in the air, and they fell rapidly, smashing into the large wooden basin filled with water, making a crisp sound of entering the water.

"Poof!"

This time, everyone's eyes widened and they looked closely!

The splash in the tub is at the same time!

And there's only one voice!

These two stones hit the ground at the same time!

"How? Did you see it clearly this time?"

Wu Fan looked at everyone with a smile, and did not press step by step, but said generously: "Those who are still confused in their hearts can pick up these two stones and climb the tree to experiment by themselves, as many times as you want, until you are convinced!"

As soon as the words fell, Jiang Ruoyu became the first person, her expression was very serious, she pursed her mouth tightly, and did not say a word.

If what Wu Fan said was correct, then the concept she had adhered to over the years would have collapsed!

If even the most common perception is wrong, then how much of your own view of the world is correct?

Is such a self really qualified to be a teacher? Won't he mislead people's children?

Moreover, she always had a faint feeling in her heart: this seems to be a trivial matter, but she feels that it contains some kind of mysterious and mysterious truth of heaven and earth, otherwise why has no one said that this view is wrong for hundreds of thousands of years?

When climbing the tree, she was even a little excited, but hoped that what Wu Fan said was correct!

Because in this way, she is the first witness to this truth and the first to practice it herself.

For a magician who is keen to explore the unknown, they are not only studying magic, but everything that exists in the world is within the scope of their thinking!

It's just because magic is the best field of study right now that so many magicians are dedicated to it.

After Jiang Ruoyu climbed up, he conducted the experiment again with trembling hands.

Not surprisingly, the result was the same.

The next one was Xia Ziyan, she also climbed up with a heavy face, and after seeing the results of her own experiment, there was indescribable consternation on her little face.

The next one is Mu Yanran......

There were a total of 33 people present, except for Wu Fan, the remaining 32 people all carried out an experiment, and even some students repeated it several times without giving up, or exchanged two stones with a greater difference in weight

Head.

But there is no doubt that the result will always be the same, and not a single time will go wrong.

When the last man finished the experiment, there was a deathly silence on the grass, and everyone looked at the two stones with frowns, not knowing why.

It's obviously a common sense in life, but at this moment it seems that you don't know it?

When they were silent, Wu Fan didn't say much, but leaned comfortably under a tree to read a book, letting them slowly calm down the stirring hearts.

After a long silence, someone finally couldn't help it.

"Teacher, why do the leaves and feathers fall lightly and very slowly, and don't they fall faster than the stones......? Am I feeling wrong?"

Eventually, the student even began to doubt himself.

Wu Fan shook his head with a smile and said, "That's true! Leaves, feathers, etc., are very slow, much slower than objects such as stones!"

"Then why ......"

When the student heard this, he immediately wanted to continue to ask questions excitedly, but was interrupted by Wu Fan raising his hand.

"Regarding this phenomenon, due to the limitations of your knowledge level, the teacher cannot explain it to you! But the teacher wants to tell you: It is related to other factors! As for the specific situation, you will slowly solve it in your future study!"

Wu Fan deliberately left a suspense, he needed an extremely suitable reason to attract students' interest in science, lest they be scared away by its difficulty.

Now, there is only one common thought in everyone's minds: figure out why pebbles of different sizes fall to the ground at the same time!

Before getting the answer to this question, Wu Fan was sure: no one would give up halfway!

Even, this problem can make them tormented toss and turn, and they can't sleep at night, which is even more fascinating than the bizarre story told by Wu Fan!

Interest is always the best teacher!

"Teacher, don't waste time, let's start class now!"

Zhou Xuanwen said impatiently, he was now the most eager person to know the answer, after all, he was the first to experiment with his own hands.

"Okay, you guys get the textbooks first! Come on, the squad leader comes up, a bunch for each person!"

Wu Fan smiled and nodded, such a hungry desire to learn scientific and cultural knowledge, anyway, this phenomenon is quite rare on Blue Star.

"Heaps?"

Someone noticed Wu Fan's wording and immediately looked at it in shock.

I saw Wu Fan smiling and unceremoniously taking out a mountain of books from the system space, and if everyone's textbooks were stacked together, they would be half a head taller than others!

"This ...... So much?!"

Not to mention the students, even Jiang Ruoyu and Mu Yanran covered their mouths in surprise, unbelievable.

The Magic Continent advocates simplicity and clarity, and in the Academy of Magic, there is only one "Magic Sacred Book" in the entire learning career, and there is no other textbook!

However, now, Wu Fan is almost 100 copies in one hand, when will he learn this?

"That's a lot?"

The curvature outlined at the corners of Wu Fan's mouth became larger and larger, "Young man, these are only one-third of yours!"

"If you want to really understand science, how can you do it without a few hundred copies?"

Hearing Wu Fan's words, many students' faces turned green, and they watched Wu Fan like a hard-working little bee, tirelessly holding out a full pile of books from the space ring, and his face was filled with a very happy expression, it seemed that this was a great enjoyment for him!

The trembling bodies could no longer explain the remorse and even despair in their hearts at the moment!

Wu Fan's heart continued to swell with strong pleasure: "The way of heaven is good reincarnation, who does the sky bypass!" tremble, scum of the magic continent, let you feel the bitterness of hundreds of millions of Blue Star students!"
