Although it is cold at this time, the sun still hangs unyieldingly high above the head, spreading its heat energy to the earth, shining and warming the people on this earth.
Thermal expansion and contraction...
Hua Xi's eyes lit up, he raised his head to the sky and roared, applauding his idea.
The principle of thermal expansion and contraction. Hua Xi learned about this aspect of physics when he was in junior high school.
Although the theoretical knowledge is available, Hua Xi has never done any hands-on experiments. Perhaps this is the tragedy of our country’s education system. From this point of view, it is not difficult to see why most Nobel laureates are foreigners. It is not difficult to see the shortcomings of the national education system.
The media is full of the theory that bad universities are expanding their enrollment and graduation equals unemployment. If I hadn't been smart and smart, I would have continued to live on my meager salary and become a victim of the education system.
In this era, the theoretical knowledge learned in the past can be best verified here. Although it is only theory, it is the result of countless experiences of predecessors. I believe there is nothing wrong with it.
Hua Xi called some tribesmen to him, first ordered them to light a fire, and then he put a half-meter square stone on the fire to bake.
After baking, the snow on the stone has already turned into water vapor, which evaporates and sublimates in the air, making the stone gradually become hot to the touch.
Seeing that the fire was almost done, Hua Xi ordered the tribesmen to put the stone on the ground, took a ladle of ice water and sprinkled it on the place where they had just been baked... There were a few crackles, and a burst of white smoke rose up. After the smoke dissipated, everyone suddenly
It was discovered that dozens of irregular cracks, like turtle patterns, suddenly appeared in the area where the ice water had been poured.
"Chisel, copper hammer!" Hua Xi shouted in a low voice
Soon, the chisel and copper hammer were handed over by the clansman. After Hua Xi took them, he picked up the chisel and copper hammer and struck hard at the crack. Stone chips flew into the air. Under Hua Xi's rhythmic tapping, one after another,
A small pit fell and continued to grow under the impact of the chisel. When it could no longer be knocked out, Hua Xi once again asked several tribesmen to put the same part of the stone on the fire to bake, and then repeated the previous steps, a deep
A deep pit measuring tens of centimeters and as wide as a palm was struck out
"Wow, the patriarch is amazing!"
"Hey, this must be the power given by the gods!"
"Ming Rui, the great Huawei, the god in charge of fire and the sun..." (In order to commemorate the most powerful private enterprise in our country, and also to highlight the legendary effect, Hua Xi named the God of Fire: Huawei, indicating that he is Chinese
After seeing the amazing power displayed by the clan leader, the clan members knelt down and worshiped Hua Xi, shouting
"Oh hahaha..." Hua Xi burst out laughing, feeling proud that he gave himself the great title of the originator of the magic stick.
After feeling proud for a while, Hua Xi stood up and said seriously: "Did you see it? The omnipotent Huawei has given us the power of fire. You just need to follow the steps I just followed and carve out such a big hole in those big rocks. Remember."
Stop, don't cut through!" In order to ensure that the lengths of the waterwheel supports are roughly the same, Hua Xi specially carved a mark with charcoal on each selected stone that was basically the same size, which meant that every time he chiseled here, he would
That's it
"Yes!" The tribesmen answered loudly while looking at Hua Xi with fanatical eyes.
After half a day of observation, after the tribesmen had mastered how to use thermal expansion and contraction to process and transform stones, Hua Xi inspected the manufacturing of various parts of the waterwheel. The work on wheels, bearings and other parts went smoothly.
After experiencing the initial bottleneck, the manufacturing progress was as smooth as flowing water, with no obstructions.
Time flies so fast, and in the blink of an eye it will be five days later
Hua Xi, who had been braving the freezing weather outside and accompanying his people on the front line, returned to the tribe and after a day's rest, he came to the papermaking workshop in high spirits again.
When a slave of the Keni tribe saw Hua Xi coming to test the work of his group, the slave boldly asked: "Chief, is this okay now?"
"Well, you did a good job," Hua Xi replied, reaching out and stroking the round hole on a stone, and said, "Polsh this round hole again. It's best to polish it smooth, so it doesn't irritate your hand. Then it will be perfect!"
Hua Xi admired it. Looking at the group of excited slaves in front of him, Hua Xi's heart moved and he said, "Are you slaves now?"
Several slaves nodded, and Hua Xi continued: "Work hard, the great God of Fire will never forget those who have contributed to the Chinese tribe! You will soon be able to qualify as civilians of our tribe. During this time,
You behaved well and there are clear rewards and punishments, you should be rewarded!"
Under the astonished gazes of several slaves, Hua Xi turned to an elder who oversaw the work and ordered: "Give them double the food."
"Ah, Patriarch Xie..." The slaves quickly came to their senses after a brief daze, and quickly knelt down to bow to Hua Xi.
After five days of hard work, the waterwheel parts work is coming to an end.
In the past few days, Hua Xi, who had ignored internal affairs for a long time, also met a carpenter named Mulu under the introduction of elder Hua An. This man was originally a tribe's predecessor and a Shui tribe. He built his first modern engineering "village".
"From the beginning, he has been learning the art of building houses with him. According to Hua'an, Mulu has been deeply interested in wood since the construction of Chinatown, and he has been studying hard. Now he is the best carpenter in the tribe.
The owner of a private woodworking workshop with more than a hundred apprentices
Hua Xi, who paid little attention to what was going on in the city, just realized that the dirty tribesman in front of him who was hiding in the mud turned out to be a prestigious figure in the city.
Mulu suddenly caught a glimpse of the patriarch walking towards him, and knowing that he wanted to see the progress of the waterwheel manufacturing, he quickly took out a gear from a pile of wood, stood up and said, "Chief, can you see if this gear is suitable?"
Hua Xi nodded, took the gear with a smile and looked at it carefully. After a closer look, Hua Xi was shocked to realize an old saying: There is no false person under the reputation.
The gear is as wide as a palm, but whether it is a set of sharp teeth, or the nut in the middle, the inner ring part is carved very delicately by Mulu. Although it does not require the precision of later generations, with the current production tools and knowledge
, who can make this level of precision, Mulu is definitely the best in the world, at least second in the tribe, no one dares to challenge the first.
Hua Xi patted Muru on the shoulder and praised him: "Muru, your carpentry skills are known to be the best in the tribe. Do I still feel uneasy about your work? Haha!"
When Mulu heard the patriarch praising him, his face immediately showed a happy and proud look. Indeed, he knows best how many abilities he has.
Trust belongs to trust, but Hua Xi still checked it several times in person. It was the first time to build a water tanker. It is better to be cautious. After detailed inspection, Hua Xi turned to face the more than a hundred tribesmen who gathered at the workshop address and shouted: "Loading"
The waterwheel project has begun, everyone should watch it carefully. If you encounter a place that still needs a waterwheel, you can build it yourself."
In fact, he didn't need to shout, everyone's eyes were focused on him and he spoke unceremoniously. Hua Xi just took a breath away from his tribe, and people would notice.
