"What is a hot air balloon?" Zu Mingjun and Li Gaoming came in together, looking curious.

    "Hahaha, let me tell you a good news. Merton has given us another idea. We''re going to make a name in history." Wei Chi Baolin danced excitedly.

    Think of their grand plan. The three couldn''t help giggling. After learning about Qin Huaiyu''s plans, Li Gaoming looked indifferent, but Zu Mingjun was full of envy. After all, they could have the opportunity to remain famous in history, and few people could refuse this opportunity.

    "Unfortunately, our ancestors have divided the PI to the extreme. No matter how hard we try, we can''t surpass our ancestors?" Zu Mingjun said with regret on his face.

    "Why is it difficult? Since your ancestors achieved the highest PI, why don''t you think of other patterns? Why hang from this tree," Merton said.

    "How can it be so simple? The common patterns in the world have been studied thoroughly by the ancestors of mathematics. Even Zhao Shuang has worked out the Pythagorean theorem. Our descendants are really out of time." Zu Mingjun said regretfully.

    "Really? That''s too bad for you! It''s all discovered by your ancestors. Then give you a walnut to comfort your injured heart." Merton saw a plate of walnuts on the table, picked up a walnut and threw it gently to Zu Mingjun.

    But I didn''t expect to use too much force. Zu Mingjun didn''t receive it at once. He directly hit Zu Mingjun''s head. Merton threw the second one. Zu Mingjun stretched out his hand and received it.

    But Merton did not stop. Instead, he threw a plate of walnuts one by one to Zu Mingjun, and Zu Mingjun''s eyes became brighter and brighter, allowing walnuts to fall on his body, head and arm.

    "What''s matter with the you?" Wei Chi Baolin was confused and wanted to find out, but he didn''t want Li Gaoming to catch him.

    Wei Chi Baolin looked at Li Gaoming in surprise. Li Gaoming shook his head. He saw that Zu Mingjun was in the stage of Epiphany, and the source of epiphany was Merton''s continuous walnut.

    A plate of walnuts was about to be thrown away. When there were only the last four, Merton suddenly changed his direction and threw the four walnuts one by one to the other four people.

    Four walnuts were thrown away from zumingjun''s eyes with a beautiful gesture. Zumingjun had a flash of inspiration. He hurriedly picked up a goose feather pen in his hand, grabbed an advertising list of ink technology exhibition and drew it.

    Merton smiled and put the empty plate aside. The four looked at the walnuts in their hands in a daze and looked at Merton and the stunned zumingjun with a surprised face.

    At the moment, the ancestral monarch is like the attachment of his ancestors. Lingguang doesn''t want money. His mind is full of walnuts, which pass through his eyes, replace walnuts into a point, and the track of walnuts becomes one line after another.

    Zu Mingjun painted these lines one by one on the advertising list, and threw them away. Soon, the whole house was full of waste paper.

    When Zu Mingjun drew a semicircle unconsciously, he suddenly realized and danced excitedly.

    "Hahaha! I see! I see!" the ancestral name Jun Ru is crazy.

    Zu Mingjun picked up a brand-new rice paper and drew a whole parabola on it. And indicate the starting point, the highest point and the falling point one by one, just like the cross-section of a bowl buckled on the ground.

    "What''s this?" Chumo rushes over and looks at the reason why zumingjun is stunned.

    "This is the trajectory of walnuts thrown in mid air," Zu Mingjun explained.

    "What''s the use?" the four were confused.

    "Hahaha, of course it''s useful. With this opportunity, Zu also has a place in history." Zu Mingjun looked at the people.

    The crowd looked at him. They couldn''t help itching their teeth and directly responded to him with a burst of walnut rain.

    After the crowd frolicked for a while, Zu Mingjun proudly showed off his achievements to the crowd.

    "An object is thrown high from the ground. After passing through the highest point, its landing point has been determined. This is an unprecedented pattern. It was first discovered by my Zu Mingjun. I call it a parabola." Zu Mingjun proudly explained the principle of parabola to everyone.

    Merton speechless, as like as two peas, the historical inertia is very strong.

    "This is similar to the principle of bows and arrows. If this thing is used well, it should be able to calculate the falling point of bows and arrows." Cheng Chumo is worthy of a family of generals and points out the purpose of parabola.

    Merton nodded, which is indeed the most important use of parabola at this stage. However, the use of parabola will shine in the future. Parabola is required for projectile trajectory and intercontinental missile trajectory. More importantly, parabola involves the application of quadratic function. If Zu Mingjun can understand the essence of parabola, it will greatly improve Chinese mathematics and leave a name in history.

    "So Merton''s Walnut woke you up?" Qin Huaiyu said with a smile.

    Everyone suddenly realized that it was Merton who continued to throw out walnuts, and the ancestor Mingjun could suddenly realize the track of walnuts.

    The crowd couldn''t help but marvel and looked at Merton strangely.

    "Thanks for brother Mo''s Walnut kindness," said Zu Mingjun with a solemn gift.

    Merton quickly dodged and said modestly, "that''s brother Zu''s own talent in arithmetic. I just see if you get something, I will continue to throw walnuts. How dare I take credit? I was afraid you blamed me for losing walnuts all the time?"

    Merton gently picked himself out. He had found that Zu Mingjun was very powerful in mathematics, and his Arabic numeral addition and subtraction was a piece of cake in front of him.

    In other words, Li Gaoming and Qin Huaiyu are like primary school students, while Zu Mingjun is already a junior high school student. It was no longer appropriate for him to study primary school courses. Merton indirectly found another difficult course for Zu Mingjun.

    "Anyway, I can understand the parabola. Brother Mo, your walnut skill is indispensable." Zu Mingjun also playfully pushed away his hair on his forehead and showed the red mark of smashing.

    Everyone burst into laughter, and the whole atmosphere suddenly became cheerful. As for the truth of the matter, as long as the parties know it clearly in their hearts.

    "I didn''t expect that Morton has the ability to enlighten when smashing a walnut. Since it''s so magical, Morton would also smash me with a walnut! See what I can understand!" Qin Huaiyu put his head together.

    "Your head is too hard. I don''t think walnuts alone can do. What do you think of this stool?" Merton raised a stool and tried to smash Qin Huaiyu.

    "That''s not good!" Qin huaiyufei retracted his head. If a stool is smashed on it, it will break your head and bleed blood.

    "What a pity! You wasted a chance to remain famous in history!" Merton said regretfully.

    "Seriously?" Qin Huaiyu said suspiciously, even a little eager to try.

    "Of course, history books must record that Qin Huaiyu died in the ninth year of Zhenguan at the age of 15." Merton said with a smile.

    "Ha ha!" the crowd burst into laughter.

    "Get out!" Qin Huaiyu''s face was black.

    The so-called young mind is not so ignorant and worried. Merton is a man for two generations. Once again, he feels that coming to Datang is not a bad choice.
