Learn mathematics, physics and chemistry well, and you will not be afraid to travel all over the fairy world! Chapter 13 My timing compass is too rough?
"Junior sister, your watch... the chronograph compass is too rough." Mu Heng took Luo Yunjin's chronograph compass and studied it carefully for a long time. He didn't understand its operating principle, but the scale on the dial made Mu Heng
There are endless flaws in my heart.
"Ah? This compass is so exquisite and feels good in the hand, but it is one of my favorite objects. How come it turns into rough in my senior brother's mouth?" Luo Yunjin seemed to be unhappy and aggrieved when he heard this. This was last year.
It was a gift given to me by Senior Sister Yang Lan on her birthday. I have liked it for a long time.
Besides, Senior Sister Yang Lan is the chief weapon refiner of Butian Pavilion, and is now able to practice seventh-grade magic weapons.
Mu Heng was speechless when he heard this. Sure enough, girls and boys pay different attention to things. Am I talking about whether it looks good or not? There are only twelve scales on this dial, and the number is the number of the earthly branches. Then, and then there is no more.
Already.
Moreover, looking at the twelve characters "Zichou Yinmao" marked on it, it is obvious that they were written based on feeling, and it can be seen with the naked eye that there are no equal parts.
If you use this timer to do an experiment, the result will be roughly like this:
It takes one hour to absorb full water spiritual energy, one hour to absorb fire spiritual energy, and one hour to absorb wood spiritual energy.
Nima, what's the use of this? Can it show the difference?
"No matter how beautiful it is, it's useless." Mu Heng was still accustomed to the 12-hour timekeeping method on earth. After thinking about it, he asked again: "Junior sister, can I change this compass?"
"Change? Senior brother, do you know how to refine weapons?"
"Item refining? That's not very good, but it shouldn't be a big problem with local adjustments." It's just to increase the scale by an order of magnitude smaller. I don't understand the principle of its operation, so I can only make some superficial remarks.
"Senior Brother, you can change it however you want." Luo Yunjin also doesn't believe that Mu Heng knows how to refine weapons, so he shouldn't destroy the compass. Besides, with Senior Brother's first-level cultivation in the Ten Directions Realm, it's not easy to destroy the compass.
possible.
According to the earth's ancient timekeeping units, one hour is two hours, one hour is divided into eight quarters, and one quarter is 15 minutes. Mu Heng thought to himself: "Let's use the quarter as the smallest unit first."
The operation is also simple, just divide the scale corresponding to the current hour into eight equal parts. After thinking for a while, Mu Heng planned to make a simple compass first, and then a ruler.
"Junior sister, lend me your fairy sword." Mu Heng plans to use bamboo to make these two things. The direction of the fiber of bamboo is conducive to strengthening the straightness of the ruler. It is the first choice material for making rulers and compasses. Moreover, the bamboo forest behind the house
There are a lot of withered bamboo poles here and they are easy to find.
"Senior brother, here you go."
For the first time, Mu Heng carefully observed the sword. It was about 90 centimeters in length and belonged to the category of dagger. The blade was about 3 centimeters in width. It was stainless steel in color and engraved with flowing sword patterns. The blade was not very sharp. Come to think of it, the sword was not very sharp.
The fairy sword is a magical weapon, not for slashing.
The sword grid is trumpet-shaped and made of fine wood, echoing the cloud-shaped sword pier. The hilt is wrapped with a layer of animal leather.
It seemed to feel cold in the hand. He flicked the sword with his index finger, and heard a crisp and orderly vibrato. Mu Heng heard the vibrato with a stable frequency. Based on the general principle of sonic flaw detection, he deduced that the material inside the sword was uniform and basically flawless.
"What a sword." Mu Heng praised sincerely.
Seeing Mu Heng playing with his fairy sword and making a sound of approval, Luo Yunjin felt happy and echoed: "That's right!"
Mu Heng took a bamboo pole as thick as a fist, took the longest bamboo tube in the middle, and used his sword to split the bamboo tube into pieces as thick as chopsticks. He continued to flatten two slender bamboo boards, and drilled a small hole in one end.
, insert a bamboo stick to form a simple hinge.
Cut a hole in the other end of the two bamboo boards, insert a pointed bamboo skewer on one side, and insert sharpened charcoal on the other side. A simple compass is ready.
Luo Yunjin sat aside and watched Mu Heng's every move intently, including a series of chopping, cutting, and drilling movements. Although the movements were simple, he could not understand them. However, the senior brother's focused expression did look a bit handsome.
Looking at the finished product in Mu Heng's hands, Luo Yunjin didn't know what it was used for. After Mu Heng drew a regular circle for her, she jumped up with joy, as if looking at a treasure. Looking at this called
Compass thing.
Regardless of Luo Yunjin's excitement, Mu Heng then began to make a ruler. The ruler was not difficult, and it could be corrected directly by using the principle of linear propagation of light.
Finally, Mu Heng worked for a whole hour to get these two things done. The reason why it took so long was because Mu Heng strived for accuracy. The greater the error of the ruler and compass, the greater the impact on the subsequent drawings, so he had to
meticulous.
The next step is to mark the dial. First use a compass to compare the diameter of the dial, and draw a circle of the same size on the paper. Then use a ruler and compass to divide the circle into 24 equal parts, and then subdivide each large scale.
into 8 small scales.
Luo Yunjin looked at Mu Heng drawing left and right on such a small circle, and the sight of the straight lines made her scalp tingle: "Brother, what is this drawing? It's so messy?"
"This is called chaos, it couldn't be more neat." Mu Heng didn't pay attention to Luo Yunjin's question. This kind of picture is not beautiful or ugly based on appearance, its beauty lies in equal parts.
The scales have been divided, and the next step is to draw the scales according to the dial. Mu Heng removed the circles on the paper, leaving only the scales, and then used the remaining outer ring template to put it on the dial, and just traced it in black. The original
Anyway, the position of Zichou Yinmao has not shifted much, so no adjustment will be made.
After doing all this, Mu Heng returned the brand new chronograph compass to Luo Yunjin with satisfaction, and explained the use of the new compass to her in detail.
Luo Yunjin looked at the compass in his hand. Originally there were only words on the scale, but now there were many vertical lines between the words, some were long and some were short, and he didn't know how sharp they were. But when he heard Mu Heng's explanation as if he was chanting sutras, it was like listening to a book from heaven.
In the fog.
Finally, when Mu Heng told it for the eighth time, Luo Yunjin burst out: "Ah...ah...Senior brother, please stop reading. You don't understand. I don't know how."
Children who have never studied mathematics are so pitiful, no, children who have never studied mathematics are so happy. At this moment, Mu Heng suddenly had a new understanding of the girl in front of him: silly, sweet, and a complete science idiot.
.
Mu Heng said it all. Seeing that the silly girl still didn't understand, he gave up the idea of teaching her and smiled bitterly: "Forget it, just tell me the starting position when you help me time the time tomorrow."
Feeling the pain of being tortured by mathematics, Luo Yunjin hurriedly flew away without waiting for Mu Heng to send him off. Before leaving, he also took away the compass and ruler made by Mu Heng.
Mu Heng didn't care. Anyway, the goal had been achieved. It didn't matter if there was a ruler or not. Besides, it was easy to make, so just treat it as a small object for her to play with.
----------------------------------------
When Mu Heng had fallen into a deep sleep, a roar came from the Butian Pavilion, the main peak not far away: "Who said that my timing compass is too rough?"
"Senior Sister Yang Lan, please calm down. There is someone who you don't recognize even if I tell you." Luo Yunjin saw that Yang Lan was about to go into a rage and quickly advised him.
After leaving Mu Heng's place, she originally wanted to go back to Xiulou to rest, but before leaving, she was thinking about that new thing, called a compass and ruler. A thought that made her happy came to her, and she took it away conveniently.
Go straight to the Butian Pavilion of the Weapon Refining Pavilion in Yuqing Xingzhai.
"Senior Sister Yang Lan, look, that person drew a lot of vertical lines on the original timing compass, saying they were small scales." Luo Yunjin didn't understand Mu Heng's explanation at all, and couldn't explain the connotation of the scales at this time.
I can only capture a few keywords.
"Oh?" Yang Lan angrily took over the chronograph compass, carefully observing the dense vertical lines with her beautiful eyes, and Luo Yunjin's unclear words came to her ears, what about three quarters at noon, four quarters at noon.
Although she couldn't understand Luo Yunjin's expression, the special words between the lines and the even and orderly lines on the dial made Yang Lan understand the meaning of these vertical lines at once.
"So that's it, I understand!" Yang Lan, who wanted to understand all this, couldn't help shouting as a light flashed in his eyes. His originally livid face turned red under the uncontrollable excitement.
"Ah, senior sister, do you really understand?" Luo Yunjin asked with surprise and suspicion when he saw Yang Lan's crazy and excited expression.
She listened to it eight times but didn't understand it. And she also knew clearly that she didn't understand what she told her senior sister. To be honest, she didn't understand it herself. She just recalled Mu Heng's words from memory.
"Okay, I understand. Regardless of the person's level of weapon refining, just by narrowing down the scale, he can be called a weapon refining master." Yang Lan's attitude towards weapon refining is extremely strict, which is why she can reach the seventh level at this age.
The weapon refiner's greatest reliance.
Regardless of whether Yang Lan really understood it or not, the praise from the master from his senior sister's mouth made Luo Yunjin's heart feel as sweet as honey, and his innocent face was filled with contented pride.
If senior brother knew that he was so highly praised by a seventh-level weapon refiner who never praises others, he would probably be happy in his heart. Luo Yunjin was smiling silly beside him, and his inner activities were as exciting as a movie. Senior brother is only a first-level person in ten directions.
The little monk, in the words of his senior brother, is called Xiao Mengxin.
Yang Lan, who was still studying the scale over there, didn't notice Luo Yunjin's silly smile. She was focused on the scale, and she couldn't help but have many doubts in her heart: It's not difficult to draw such a small scale, but how to ensure that the painting is even?
I think when I marked Zichou Yinmao, I wrote it based on my feeling. It just looked symmetrical, but upon closer inspection, it was still not symmetrical and balanced enough: If I can master this method, I will make weapons according to the standard in the future.
That will greatly increase the success rate of refining the weapon.
Yang Lan quickly realized the role this technology could play in weapon refining. Although she still couldn't figure out how to operate it, it did not hinder her vision of innovation in weapon refining technology.
