"In this way, I, a Confucian student, am useless at all, Master Inspector, what else can I do?"

Yang Tingshu smiled bitterly, Zhu Jie's tirade has completely defeated him, he almost never thought about these problems, since he was a child, he has been reading poetry and books since he was a child, and he is penniless when he comes to Zhu Jie!

Zhu Jie smiled: "Brother Fu'an, why do you want to be arrogant? I'm just saying that Zhu Cheng has no merit in science, did you say that Confucius and Mencius's original Confucianism is not good, not to mention that there is a specialization in art, in the practical field, you may not be comparable with Brother Man, but are you not the imperial envoy of Nanjing now? In the position of the imperial history supervisor, I believe that you are better than any one of you, you don't have to worry about other things, your task is to supervise officials everywhere, no matter who it is, once you commit a traitor, you will be severely punished, let go of your hands to do it, and you will not be able to control the corrupt and dim officialdom! ”

Yang Tingshu's expression was grim, and he replied: "What Master Inspector said is that it is me Meng Lang. ”

Huang Zongxi smiled bitterly: "My lord, is this Galileo you said really so magical?" ”

Zhu Jie nodded and replied: "At the very least, everyone here is tied together in the study of things, and she is not as high as her achievements, I can give you a strength." ”

Zhu Jie picked up the brush again, sketched a few strokes, and said: "Gentlemen, please see, it is known that a cannonball was fired at an angle of 45 degrees and fell 300 zhang away, I ask you to solve the speed of the cannonball at the moment when the cannonball hits the breech!" Second, it is known that the speed of the cannon is fifty miles, and it is fired at an angle of thirty degrees, may I ask, how far will this shell fall! I don't know who can use an abacus to calculate this data! ”

Everyone here was dumbfounded, how can this, how can this be calculated?

Everyone looked at Huang Zongxi and Fang Yizhi one by one, and the two of them can be said to be the two most brilliant people in the history.

Fang Yizhi and Huang Zongxi frowned, how can this be calculated, the conditions are too simple, right?

"Master Overseer, this is inevitably difficult for some strong people, right?"

Zhu Jie smiled: "What's so difficult about this? Mr. John Tang, can you do the math? ”

Tang Ruowang's face turned red, and replied: "Master Inspector, I know what you mean, but I really can't do anything about this matter, if you want to calculate this data, you need to know the effect of gravity on the cannonball, and at the same time, you also need to consider the speed of the cannonball, and also consider the impact of the speed of the object in the air, if this is Mr. Galileo here, it must be difficult for him, I have heard that he once established the value of gravitational acceleration, and is also proficient in analytic geometry, this should be difficult for him, but for me, But there is nothing that can be done! ”

Zhu Jie laughed and said: "Coincidentally, I know the influence of this gravity on the object, and this gravitational acceleration is determined by Mr. Galileo, and with his method, you can easily calculate these values!" ”

Zhu Jie is not a scientist, but he is naturally no stranger to the calculation and research of the trajectory of artillery shells, and during high school and college, he often came into contact with parabolas, whether it is analytic geometry or calculus, he is not proficient in it, but it is no problem to roughly calculate the trajectory.

The brush in Zhu Jie's hand kept waving, and the two chapters of the decree were already full of numbers, and the results were deduced step by step!

Fang Yizhi and Huang Zongxi were already dumbfounded, what else, what else would this master not know, even arithmetic is so profound!

As for John Tang on the side, he was even more amazed, maybe Zhu Jie's arithmetic level is not as good as Galileo, but looking at this posture, it will definitely not belong to Galileo's southern students!

After a long time, Zhu Jie let out a long breath and replied: "I haven't fiddled with these things for a long time, and I'm really not used to it, Mr. Tang, come and see, how about it!" ”

Tang Ruowang came to his senses for a long time and exclaimed, "Absolutely, absolutely!" Master Inspector, if you have such a level, you should have entered the Qintian Prison as a supervisor a long time ago, I am ashamed of myself in front of you, even Galileo may not be able to calculate the exact ballistic data in such a short period of time! And our current artillery ballistic data are all fired again and again, based on field measurements, and it is impossible to use a set of axioms to calculate all the ballistic parabolas and range! This—this is definitely a remarkable achievement! ”

Zhu Jie said with a smile: "Mr. Tang, I am just standing on the shoulders of my predecessors, the real stake is the person who discovered this axiom, gentlemen, in the future war, it is obvious that the status of artillery and muskets is getting heavier and heavier, even if it is cavalry, in the face of dense artillery and muskets, it is impossible to win, as for the siege of the city, it is inseparable from the bombardment of artillery!" If we can summarize all the shell data in advance and teach it to our soldiers, then the range, angle, and accuracy of the future artillery will be greatly improved, and the current artillery, ten shells, three hit the target, it is already good, if these methods are used, make a prediction in advance, adjust the angle according to the data, then ten shells, six or seven hit the target, it can be said that there is no problem! How much time will that save us in siege, and how many fewer soldiers will die? ”

Everyone looked at each other, let Zhu Jie say this, this arithmetic and physics are really useful!

Zhu Jie continued: "This is not the most important, the study of things, the mystery of the poor world, broad and profound, the application in the field of military warfare is just one of the corners, in agriculture, the same role is huge, once the study of things is developed to the extreme, applied to crop production, such a change is earth-shattering, taking wheat as an example, with the help of the science of things, after all, one day, the yield of wheat per mu will break through to 1,000 catties, and now, the yield of wheat per mu is only about 200 catties, The yield of rice is only a few hundred catties, the application of the science of things, the rice yield is possible to break through two thousand catties, you think about it, if the yield of wheat per mu reaches 1,000 catties, and the yield of rice reaches 2,000 catties, that day, all the people will no longer be hungry. There's only one head! And with such a high yield, how much grain will it bring to the imperial court? The treasury will no longer have to worry about emptiness, and when the Tartars or red-haired pirates come, we will smash them all to death with silver! ”
