I made science magic

Good guy, I have become Galileo...

Just as Lin En was complaining silently in his heart, a voice sounded from behind him.

"How do you feel? Are you satisfied? Professor Lin En?"

The speaker was Tik, an alchemist from the Wizarding City, stroking his beard quite proudly.

After Lin En ran away on the pretext of being drunk last night, a group of professors discussed how to record this morning's shocking experiment in the form of a sculpture.

This is one of the highest honors in the entire college!

This means that every student who joins Iyetta College in the future will be able to admire each other's deeds the moment they walk through the gate of the college.

He also made some personal suggestions on the external form of the sculpture. Coupled with the magic of several professors and the hard work of the goblins day and night, it was completed in just half a day.

"It looks...well...very shocking..." Lin En said against his will. In fact, he felt that the artistic level of this sculpture was really average.

Tick ​​himself was very satisfied with this work, and did not hear the perfunctoriness in the other party's words at all. Instead, on the way to the Olympiad subject classroom, he explained to Linn how to express a wizard's inner thoughts through sculpture.

Lin En always maintained a polite smile on his face, and it wasn't until he entered the classroom that he changed to a solemn expression.

After being divided into classes, the number of people in the entire elite class was much smaller, with only forty-six people left.

No, from today onwards there will probably be forty-seven people.

Because there is one more Lydia!

At this moment, the halfling girl is sitting at the front of the entire classroom. Because she is too short, the table and chairs are all unique, one size smaller than the others, and she looks very abrupt. Lin En's first glance after entering the door

It focused on her.

Facing Lin En's gaze, Lydia did not tremble like other students. Instead, she held up a parchment roll with great anticipation and said impatiently. "Professor, can we start class now?"

Alok, Peirce and others looked at Lydia with a little pity and nostalgia in their eyes. They vaguely remembered that they were so excited on the first day of Mathematical Olympiad class.

"Since everyone is so impatient, let's start class now!" Linn turned to look at the gray-haired witch and said.

"Jionni, please collect everyone's homework..."

"I gave you a whole day, so you must have already calculated the area of ​​the Lookout, right?" Lin En said with a smile.

As soon as these words came out, there was a sudden burst of mourning in the classroom.

As members of the elite class of Olympiad mathematics, each of them has good arithmetic talents, but the structure of the Wangwang space airship is very complicated, and the best airship airbag is oval.

Even though Lin En has taught the corresponding formula before and given some data, it is still extremely difficult to calculate it accurately.

But no matter how reluctant they were, they could only hand over the calculation paper, and Lydia was no exception.

In fact, during the more than half a month of making the airship, every time Lin En took time to come over to explain the drawings to her, he would also talk about a lot of geometric formulas and theorems, so her learning progress was actually no better than those of the students in these elite classes.

We want it low.

Linn took the stack of parchment rolls that Jonny had collected. He frowned when he saw the first one and said, "Debra, why are there only airbags and cockpit areas, and the tail fins?"

"

"But you didn't give the data on the airship's tail..." the red-haired witch stood up and said weakly.

"But it can be calculated, can't it?" Lin En looked at the wizards present and explained.

"The shape of the tail can be broken down into an equilateral right triangle plus a square. I gave you a proportional plan view. If you pay attention, you can find that a hypotenuse of the cockpit is parallel to the hypotenuse of the airship's tail.

, the length is the same. Since there is data on the hypotenuse, other data can be easily calculated using the Pythagorean Theorem..."

This is not easy at all... The red-haired witch looked sad.

Lin En, however, was merciless and said directly. "When you go back, copy the corresponding formula fifty times! Also, before get out of class is over, recalculate the data for me!"

All the students in the audience couldn't help but shrink their necks. They couldn't even calculate the area of ​​the tail fin.

"What is this Pythagorean theorem?" Tik turned to look at Alok and asked in confusion.

"It's a calculation rule discovered by the professor. For a right triangle on the plane, adding the squares of the lengths of the two right-angled sides will be equal to the square of the length of the hypotenuse..." Alok read his notebook several times

After confirming that he was right, he looked vaguely excited.

Having participated in yesterday's investiture ceremony, he naturally knew that he was in front of a three-ring wizard and master of alchemy!

Such a big shot is actually asking me questions!

Elok feels that this is probably the most glorious moment in his life!

"What's a square?" Tik then asked, these nouns were all unfamiliar words to him.

"Squaring is the multiplication of the same two numbers..." Alok was so convinced that he didn't even look at the formulas in his notebook. Then he introduced the alchemist master to the area formulas of circles and polygons.

A look of understanding appeared on Tik's face. When he was learning to draw the pattern of the magic circle, he noticed similar patterns, but he did not summarize the patterns of each shape like Lin En, and formed a pattern.

an independent discipline.

Some alchemists in the Wizard City like to ponder these things. I heard that some people have even pushed the pi to the ninth decimal place. It is already extremely accurate and cannot be more accurate...

Alok glanced at Lin En on the stage, guessing that he hadn't talked about his homework so quickly, and a bold idea came to his mind. He looked at Tik and spoke with an anxious expression.

"Mr. Tick, some time ago, Professor Lin En invented an interesting game. I wonder if you are interested?"

"What game?" Tik was somewhat curious.

Alok immediately became excited, picked up the quill, and casually drew a three-by-six square on the parchment. After thinking for a while, he crossed out the last square, and then explained the rules of the game.

Read it again.

"Starting from one copper coin, does the amount of the next square have to be doubled compared to the previous square?" Tik repeated it, and then wondered why Alok had to specifically cross out a square.

"Yes, as long as you can fill all the grids, then these ten gold coins are yours!" Alok directly took out all his savings, and then continued. "But any corresponding coins you put down will also be yours!"

be mine!"

The difference between one copper coin and ten gold coins is a hundred thousand times...

Tik became more and more interested in this game. He calculated it silently in his mind, then picked up a pen and filled in the squares.

When filling in the last number, Tik was surprised and said with interest.

“Interesting, really interesting!”

The seventeenth square is sixty-five thousand five hundred and thirty-six, so the sum of all the values ​​​​is...

"A total of 131,071 copper coins!" Alok responded quickly.

Tik took more than ten seconds to simply add it, and it was exactly right.

He knew from the beginning that he would lose. After all, the wizard apprentice in front of him could not give him money in vain, but he did not expect that the addition of the seventeen small squares would actually increase the initial value by 130,000 times.

So, the other party specifically crossed out a box because they were worried that the amount was too high and they would regret it?

Tik suddenly didn't know whether to laugh or cry. Since he didn't bring any silver or copper coins, he took out four magic gold coins and put them on the table. He was always willing to admit defeat!

"Three gold coins are enough!" Alok didn't dare to ask for more, so he quickly pushed one back.

The alchemist master in front of him was not the first person to be tricked by him. After being frustrated by Professor Linn, he immediately went home and played this square game with his father, Albert.

In the end, he theoretically won all the family property, and Albert still owed him tens of thousands of gold coins... But in the end, he didn't get a penny, and he was severely beaten!

At this point, he understands the truth that if you are too greedy, you will get beaten...

Fortunately, this master alchemist is a man of his word!

Elok accepted the three gold coins happily, but the next second he heard a familiar voice on the stage.

"Alok, since you know all about the Mathematical Olympiad formulas, why don't you take the stage and explain it to everyone!"

The joyful expression on the fifteen or sixteen year old boy's face suddenly froze, he shivered uncontrollably, and stood up slightly tremblingly.

Lin En looked at him very "kindly".

Good boy, you really have a way of using the knowledge I gave you to trick others!

Under the gloating gazes of all the students, Alok had no choice but to walk to the podium, pick up a parchment, and use his shallow knowledge of Mathematical Olympiads to talk about it...

Alok has never felt that time is so long in his life. He has forgotten everything in his mind due to the tension. From time to time, bursts of laughter can be heard from the audience. In the end, he only stayed on the stage for more than ten minutes before he was expelled.

.

Taking into account the learning progress of Tick and Lydia, Linn reviewed the geometric formulas that he had taught before in the next class period.

When get out of class was over, Tik also gave him a gift in return, a book four fingers thick - "Rune and Alchemy".

Although there are some basic alchemy books in Ieta Academy, they are nothing compared to those given by an alchemist master.

Lin En flipped through a few pages. In addition to the analysis of some basic alchemical runes, this book also had notes written at the bottom of each page.

There is no way that so many notes were written temporarily. They should be the "textbook" used to teach a certain core apprentice.

Even so, it is a very precious gift, which means that when learning alchemy, you can avoid a lot of detours.

Lin En said a few words of courtesy and put away the alchemy book.

Tick, who had just finished a Mathematical Olympiad class, was filled with all kinds of questions that needed Linn's answers. However, after glancing at the halfling girl who had been hanging around since get out of class, he was very enlightened. He said goodbye and left.

"Professor Linn!" Lydia immediately came up, put her bulging money bag on the podium with her feet, put it on her waist, and said proudly.

"Yesterday, we sold 837 tickets all day long, totaling 83 magic gold coins and 70 silver coins, all here..."

The halfling girl kept talking about the grand event in the square yesterday afternoon. The team taking the airship lined up all the way to the pier of the harbor. Everyone couldn't wait to fly to the sky to take a look...

Linn was a little surprised to have sold so many tickets in just one day. It seemed that the charm of flying was greater than he imagined.

"By the way, there is also this account book. Uncle Darren asked me to give it to you!" Lydia took out another portable booklet and stuffed it into Linn's hand, which recorded the list of all people who purchased tickets.

It even clearly states which batch of airships are on board.

Lin En asked Zhinao to write down all these data, and then took out the eight gold and thirty-seven silver pieces belonging to the halfling in the purse, and returned them to Lydia along with the account book.

"When you go back, tell Darren that you don't have to send this thing every day. Just show it to me every once in a while."

The halfling girl's expression became a little confused, because Linn's reaction was different from what Darren and others predicted. With such a huge amount, they thought that the other party would definitely require a daily test.

Lin En didn't give any explanation. He deliberately kept some loose control over money, just to see if these halflings would do some tricks secretly.

An airship is just the beginning. There will be many opportunities to earn gold coins in the future. For example, in the Wizarding Land, they still use very backward papyrus and parchment to record text. He can make money by selling paper.

The bowl is full.

It's just that he can't do these things himself, he definitely needs to hire some trustworthy people.

It depends on whether these halflings can keep their greed.

The two were chatting when a rush of footsteps suddenly came from outside the door, and then the classroom door was slammed. Lin turned his head and looked over. He didn't see anyone at first sight. He didn't realize it until he lowered his head.

It was Darren who broke in.

After not seeing each other for a day, the unshaven halfling became much more haggard than before. He walked in and looked around. When he saw Lin En, he immediately seemed to have seen a savior and spoke in a panic.

"It's bad, Professor Linn, Ralph... Ralph is dead!"

Ralph? Who is that?

Linn paused for a moment, but before he could think clearly, the eager Darren pulled his sleeve and dragged him away.

(ps: Today is still a two-in-one chapter.)
