Jia Ba, this is the hydraulic spinning wheel you improved? ”

In the imperial study, Ran Min and Qin Mu, Cui Hao, and Wang Meng, the three minister-level ministers, stared at an object in front of them here, and next to them stood Jia Ba, a master car maker.

Jia Ba lowered his head and smiled, "Yes." Your Majesty, and my lords, this water-powered spinning wheel is different from the ordinary hand-spinning wheel or pedal spinning wheel in the past! ”

"Hand spinning wheel, the force driving the spinning wheel comes from the hand, when operating, you need to shake the spinning wheel with one hand and engage in spinning work with the other hand. The force of the pedal spinning wheel to drive the spinning wheel comes from the feet, and when operating, the spinning woman can spin with both hands. Since the Han Dynasty, hand-spinning wheels have been commonly used. And what about pedal spinning wheels? ”

"This is the earliest spinning wheel, which appeared in the Warring States period, and by the Qin and Han dynasties, it was widely used in the vast areas of the Yellow River and Yangtze River basins. The use of human feet to step on the work, freeing the weaver's hands from the lifting action, to specialize in shuttle and weft beating, greatly improved productivity. For example, the production of plain weave fabrics is 20 to 60 times higher than that of the original loom, and 0.6 to 1 meter of fabric can be woven per person per hour! ”

Immediately, Jia Ba pointed to the hydraulic spinning wheel operated by a woman next to him, and said: "In the past, the number of spindles in the spinning wheel was generally 2 to 3, and the maximum was 5. However, the improved hydraulic spinning wheel is different from the original spinning wheel, and its characteristics are: the number of spindles is as high as dozens of pieces, and the use of hydraulic drive (these characteristics make the large spinning wheel have the prototype of modern spinning machinery, suitable for large-scale specialized production). ”

Hearing Jia Ba boasting so much, Cui Hao next to him frowned and said hesitantly: "I don't know how much yarn your water-powered spinning wheel can spin every day?" ”

Speaking of this, Jia Ba couldn't help but be even more proud, and said, "Lord Shang Shuling is asking the right person!" Taking hemp spinning as an example, the general spinning wheel spins up to 3 catties of yarn per day, while the large spinning wheel can spin more than 100 catties a day and night. When spinning, enough hemp needs to be used to meet its production capacity. ”

"Wow! That's so much more! Ran Min and the others were breathtaking.

As far as Ran Min knows, this so-called water-powered spinning wheel appeared in the Song and Yuan dynasties.

The water-powered spinning wheel is an important invention of the application of natural forces to textile machinery in ancient China, such as the spinning machinery with water power as the driving force, China is more than four centuries earlier than the West!

But Ran Min is now rewarding inventions, encouraging everyone to use their brains, as long as you can invent something useful, no matter how big or small the effect is, the imperial court will give a certain reward.

Some time ago, Ran Min inspected the private textile workshop and found that the spinning wheel in the workshop was really simple, the production efficiency was too low, and the supply was really in short supply. Under Ran Min's instructions, Jia Ba, who was originally building a car behind closed doors, improved the spinning wheel and came up with this unprecedented water-powered spinning wheel!

Qin Mu said with a smile on the side: "Your Majesty, with this hydraulic spinning wheel, the production efficiency of cloth will definitely be greatly improved." At that time, I am afraid that cloth, silk, and cotton clothes will pile up, and even the silkworm keepers will not be able to supply them. ”

"What's so hard about that?"

Ran Min held his head high and said: "The emergence of the hydro spinning wheel will definitely play a series of positive roles. Shall I fear the accumulation of cloth, silk, and cotton garments? If we can't run out, we will sell it and export it to the Eastern Jin Dynasty, Liaodong, Mobei, Western Regions, Tuyuhun, and even to the West through the Silk Road! No matter how many, we can sell as much as we can! ”

"As for the sericulture keepers, they can't supply it? What's so hard about that? I encourage women to show their heads and go out to give birth, and everyone should do their part for the strength of the country. I believe that women raise silkworms and spin yarn, and men plough and fight, each performing their own duties and getting their own position, so how can the country's society not prosper for a long time? ”

"Your Majesty Shengming!" Qunchen Mountain shouted.

At this time, Jia Ba suddenly smiled and took out three bead-like things from his sleeves, spread out his palms, and said, "Your Majesty, adults, look at what this is?" ”

Even the well-informed Qin Mu was a little surprised: "This can't be a pearl, right?" But it's not right, the color of pearls is not so light! ”

"Is it a stone?" Wang Meng, an otaku who likes to live in seclusion, was directly confused.

Jia Ba shook his head three times in a row, and finally Ran Min nodded and said, "Jia Ba, I really didn't misunderstand you." You've finally developed glass! ”

"What? This thing is called glass? ”

Wang Meng, Cui Hao and the others all opened their mouths wide, looking incredible.

"Not bad." Jia Ba nodded and said, "Your Majesty, according to your instructions, after repeated trials with a few like-minded alchemists, this glass has finally been hammered out!" ”

Cui Hao pinched the glass ball in his hand and admired: "Jia Ba, how did you make this thing?" It's almost the same as gold, pearls, and agate! ”

"First of all, we crush the bulk raw materials quartz sand, soda ash, limestone, feldspar, etc., dry the wet raw materials, and remove the iron of the iron-containing raw materials to ensure the quality of the glass."

The glass mixture is then heated at a high temperature (15501600 degrees) in a pool kiln or crucible kiln to form a uniform, bubble-free liquid glass that meets the molding requirements. This temperature is the most difficult to control, the melting point is too low to form, and the melting point is too high to destroy the internal structure of the glass! ”

"And then there's molding. We process liquid glass into products of the desired shape, such as flat plates, various utensils, etc. ”

"This final process is heat treatment. Through annealing, quenching and other processes, the internal stress, phase splitting or crystallization of the glass is eliminated or generated, and the structural state of the glass is changed! ”

Uh, well, whether it is Ran Min, or Qin Mu and Wang Meng, who are resourceful and have a gully in their chests, they all listened with a confused face. After all, there is a specialization in the art industry, that's all.

You can't expect a historian to figure out the chemist's inventions, or the process of research. Of course, they are happy to see the final research results!

Ran Min was quite excited, patted Jia Ba's shoulder and said, "Jia Ba, I really didn't mistake you, you are really a genius!" ”

"Thank you, Your Majesty, for the compliment!"

"Jia Ba listens to the seal!"

"The minister is here!" Jia Ba was overjoyed and immediately knelt down.

"Jia Ba improved the hydraulic spinning wheel, developed glass meritorious, the merit is in the community, and was promoted to the president of the Academy of Sciences, with a rank ratio of 2,000 stones, and the rank is the same as the six books. And named Jia Ba as the Marquis of Duting, with a reward of 5,000 yuan and 100 hectares of fertile land! ”

"Thank you, Lord Ron!"

Jia Ba was almost grateful!

Back then, Jia Ba and Xie Fei were reused by Ran Min at the same time, which was on par, but Xie Fei was already a secretary of the Ministry of Industry, and Jia Ba was just a deputy, and he became a waiter in the Ministry of Industry, Jia Ba's heart was very unconvinced!

Now, the title of the president of the Academy of Sciences, which is equivalent to the six Shangshu, and has been sealed as a marquis, is really a blessing to invite heaven!

However, Jia Ba still didn't understand: "Your Majesty, what is this academy for?" ”

"What does the Academy of Sciences do? Jia Ba, that's a good question. Ran Min bowed slightly, "Science, as the name suggests, is from the He from the fight, and the fighter is also measured, so the word science is named after the meaning of 'the science of measurement'." ”

"Science is concrete things and their objective rules, concrete seeking truth from facts, a lot of practical experience, empirical learning, and the main content of science is a specific world view and specific methods."

Cui Hao understood: "Your Majesty, isn't that philosophy?" ”

"Including philosophy, but it's not all philosophy. In layman's terms, science is not about faith, but about evidence. It is an attitude, an opinion, a method. At the same time, scientific things have paradoxes in themselves. ”

That is, things from different professional disciplines can easily be confused and considered contradictory. In fact, it reflects the multiple complex aspects of a scientific understanding of things. Science is a practical activity that makes subjective understanding and objective reality realize concrete unity, it is a bridge to the desired goal, and it is also a link between reality and ideals. ”

The more the ministers present listened, the more complicated they became, and they felt very confused.

What a piano to a cow!

Ran Min sighed and said, "Let's just say so." Whether it is philosophy, arithmetic, alchemy, medicine, astronomy, geography, biology and other fields, they all belong to the category of science. In other words, the Academy of Sciences that I want to establish will include the top people in various fields like the whole world, and gather them in the Academy of Sciences to study and discuss together! ”

"Oh!" This time, Cui Hao and they can be regarded as understanding.

However, Jia Ba felt a lot of pressure: "Your Majesty, the minister...... I don't know if I'm up to it! ”

"What's not up to the task? Believe in yourself! ”

Ran Min said: "But as long as an academician of the Academy of Sciences makes an achievement, the imperial court will give a certain reward, and even a marquis like you is not a problem!" ”

Hearing this, Jia Ba had a bottom in his heart.

Ran Min really attaches great importance to this academy that is about to be established, and as for taking out the bait like the marquis and giving money!
