Vicky's voice was very loud, almost shouting with all his might.

Rosen turned his head to look, and saw that Vicky was kneeling on the ground with a 'poof', holding the parchment in his hands high, as if the Flame Cultists were holding the Flame Sacred Scripture, and his expression was extremely reverent.

Rosen couldn't help but smile and asked, "Mr. Vicky, what's wrong with you, are you standing for too long and your legs are numb?" ”

"Leg numbness...... No! No! Vicky shouted, his face flushed, as if he had drunk a dozen bottles of rum in one go.

"Mr. Rosen, I am very ashamed now! You're right, I'm not a mathematician, you are! You are a true master of mathematics, and you have unparalleled wisdom recorded on these parchments! I bet even the gods would have agreed with me if they saw it! ”

This was so exaggerated that Hill on the side was dumbfounded.

"Mr. Vicky, are you sure you're in your right mind?" Hill couldn't help but ask in a whisper.

"Sober! Sober of course! I've never been so sober! Vicky waved his hands, and the word 'fanatic' was written all over a round fat face: "Hill, do you know that these parchments are not written in mathematics, but in the wisdom of the gods!" Oh~ My god, Mr. Rosen, you must be the bastard of the god, otherwise how could you have such wisdom?! ”

As he spoke, Vicky actually kneeled a few steps in the direction of Rosen and stretched out his hands, as if he wanted to hug Rosen's legs and kiss them.

"Is he crazy?" Hill was a little frightened, and she took a few steps back without a trace, hiding behind Rosen.

Lawson also took a few steps back, dodging Vicky's groping.

He could understand Vicky's feelings, because he was writing calculus on parchment!

Calculus, a mathematical tool, is one of the most important keys to the modern scientific society.

Rosen dared to say that in this day and age, anyone who has spent a lot of effort studying mathematics will have a sense of epiphany when they first come into contact with calculus.

Because this thing is like an artifact, those problems that cannot be solved with elementary math will be solved immediately when they come into calculus, and the ingenuity of the solution is breathtaking.

In extreme excitement, Vicky said that calculus is the wisdom of the gods, but he is not wrong.

"Knock~~Knock~Knock~~"

There was a sudden knock on the door of the study, and Veronica's voice rang out: "Rosen, what's wrong, I seem to hear someone spreading wild in your study." ”

"Come in, it's not a big deal."

The door to the study was pushed open, and Veronica saw Vicky, kneeling on the ground, looking fanatical.

"What's going on with this guy?"

Vicky was like a child who had received a peerless treasure, anxious to share it with others, and when he saw Veronica, no matter who she was, he walked over with a parchment in his hand: "Beautiful lady, come and see, come and see, come and see the wisdom of the gods!" ”

Veronica glanced at the parchment suspiciously, and found that it was full of mathematical symbols, and her heart moved, and she took the parchment and looked at it seriously, and at this look, she also fell into a big hole.

After a while, she raised her head and looked at Rosen with a complicated face: "You wrote it...... Oh, you must have written it, that's your handwriting! ”

At this moment, Veronica, who has great strength, was trembling slightly with her hand holding the parchment, she forcibly suppressed her excited heart, and said: "Before, you told me about the constant of nature and the circumcision, and they all mentioned the idea of 'limit', and I have always felt that sooner or later, you will perfect this wonderful thought. But what I didn't expect was that this day would come so quickly! I didn't expect you to expand this kind of thinking to such an extent! ”

Hearing this, Vicky seemed to have found a soulmate, and he said excitedly: "Beautiful lady, I know you understand." Isn't such wisdom worthy of worship, you say? ”

Veronica agreed with Vicky's words in her heart, but her personality was not as unrestrained as Vicky, she suppressed her excitement and asked, "This is a new mathematical idea, what do you call it?" ”

"There are two parts, the first half is the differentiation and the second half is the integration, which together is the calculus."

Veronica muttered, "Calculus...... Calculus....... Good name. ”

On the side, Vicky's mood also calmed down a little, and he looked at Rosen with a look of shame: "Mr. Rosen, I am really wrong to try to argue with a master like you about mathematical problems!" However, I can see that the parchment is still a bit more sketchy. I beg you to write a complete book describing in detail the great wisdom of 'calculus'! I believe that once this book is published, it will instantly become an eternal classic that surpasses any religious canon! ”

"This ......," Hill thought Vicky's assessment was too exaggerated.

Rosen didn't react at all, he shrugged his shoulders and said lightly, "I'll talk about it when I'm free." ”

Vicky was stunned for a moment, and pleaded urgently: "Huh? No, Mr. Rosen, I beg of you. I believe that if you write a book, you will be the greatest mathematician of all time, and this will be the case for the next 100 years, 1,000 years! ”

Rosen still didn't react, for the simple reason that calculus wasn't invented by him, he was just a porter. No matter how much Vicky praises him, in Rosen's heart, he is also praising Lord Niu and Leibniz, and it has nothing to do with him.

"Mr. Rosen, I beg of you." Vicky is such a big old man who is about to cry.

Rosen relented: "I'll write when I have time, but I allow you to share the contents of these parchments with others." ”

Hearing this, Veronica hurriedly walked up to Rosen and whispered in his ear: "Rosen, this is your hard work, it is otherworldly wisdom, how can it be shared with those mortals?" ”

Veronica's words made Rosen secretly sigh in his heart. In this era, mathematics is still a purely intellectual activity in which only superior human beings can participate, and few people associate mathematics with real life.

Veronica is like that, and so are the many magicians in the Academy of Magic. It was only in the Squirrel Club that there was a momentum for the combination of mathematics and real-world applications.

Mathematics and technology were married, and science was born. Mortals, nourished by science, begin to ascend to gods.

Because of this, Rosen brought the calculus up and handed it to Vicky.

On the other hand, Vicky had been completely conquered by calculus, and when he heard Rosen's words, he was both regretful and excited, and carefully put away the parchment as if he had obtained a peerless treasure.

He stood up and bowed to Rosen again: "Sir, it is my honor to meet you today. I was impressed by your generosity and your wisdom. Once again, I sincerely apologize to you and forgive me for my ignorance. ”

"I forgive you, go back."

"Thank you very much, thank you very much!" Vicky bowed and retreated all the way to the door, only then turned and opened the door and went out. His demeanor was extremely respectful.

Veronica's brow furrowed, and she wanted to stop it.

Rosen shook his head at her: "Winnie, don't worry, he won't waste such wisdom." ”

Veronica looked at Lawson in confusion, "I really don't know what you think. Usually so stingy, a few pieces of glass have to be sold for thousands of gold dragon coins. How can he be so generous now, and such precious wisdom should be given to others? ”

Rosen laughed: "Because the former is technology, and the latter is thought." ”

"I don't understand." Veronica still didn't understand.

Lawson pointed at Hill and said, "Ask her, is it the theory of magic or the magic that is important to a magic apprentice?" ”

Veronica looked at Ciel.

Hill said as a matter of course, "Of course it's the specific magic that matters. In the academy, everyone can learn the theory of magic, but magic must be taught by a mentor and must be bought with money. For example, if you want to learn 1-star magic flash, you must give your mentor at least 100 gold dragon coins. ”

Veronica didn't know much about how the Academy of Magic worked, and wondered, "If you know the theory of magic, why don't you explore it yourself?" ”

Hill shook his head repeatedly: "How can it be so easy." Let's talk about the 1-star magic flash technique, this magic is very dangerous, if you don't have a mentor to guide you, you can explore it all on your own, and you will lose your life if you are not careful. Each specific magic, its casting skills and points, cost a lot of money, time, and even human life to determine, and no single person has the ability to do this. ”

Veronica thought thoughtfully.

Rosen continued: "To me, mathematics is the equivalent of magic theory, and the moon wand and battery I sold are specific magic. ”

Veronica still didn't think it through: "Then according to what you say, isn't the theory of magic useless?" ”

"It works." Rosen walked back to his desk and sat down, picked up the quill, spun it around in his hand, and said, "The more people who know calculus, the wider the spread, and the greater the influence." As the presenter of ideas, what do you think will happen? ”

Veronica subconsciously said, "You will be respected by countless people, and you will have unparalleled prestige in the field of mathematics." ”

Rosen smiled slightly: "It's not just the field of mathematics. ”

"Huh?" Veronica couldn't figure it out again.

"Watch patiently, you'll know later."
