Michelin moves very quickly.

The paper "On the Role of Rubber in Wiping Pencil Handwriting" was written and submitted to Science magazine the day after he discovered this characteristic of rubber.

At the same time, the Michelin rubber workshop immediately vacated a rubber rub production line.

The continuous rubber rubs were produced at a rapid speed and then appeared in various shops.

The speed of marketization of this research results has definitely set a historical record.

"Prince, this Michelin is really lucky. He can even discover this special function of rubber."

Wu Meiniang put down the "Da Tang Daily" in her hand and talked to Li Kuan.

This thing created by Michelin is naturally interested in the newspaper.

Luo Binwang specially arranged a writer to interview Michelin and learned about the background of the birth of rubber rubs.

Then a small story that attracted people's attention was born.

In the scientific community, it seems that all discoveries, if they can be accompanied by a short story, will appear more perfect.

For example, when Michelin was drawing a picture, she accidentally drew an extra horizontal line, and accidentally picked up a piece of rubber to wipe it, and then accidentally discovered the function of rubber.

This kind of short story is the most popular among everyone.

Just like people from later generations, when they mention the gravity of the earth, they will think of the story of Newton standing under a tree and being hit by an apple in the head.

The authenticity of this story is no longer possible, nor is it meaningless to investigate in depth.

In fact, did Newton really think of gravity because of such an apple?

Then this apple is too magical?

"The path of scientific development has many things discovered by various unexpected experiments. Rubber rubs are not the first or the last one."

Although Li Kuan was a little interested in this short story reported in the Tang Daily, he was not too surprised.

For example, the discovery of bread was an accident.

In ancient Egypt, the slave who was responsible for making pancakes for the birthday party of the host daughter, fell asleep due to excessive fatigue.

As a result, the fire in the stove went out unknowingly.

The residual heat causes the raw dough to ferment and swell, and it is loose and soft after roasting, which is deeply favored by the owner.

In this way, bread that spread throughout the world was born in later generations.

For example, Viagra's discovery was even more unexpected.

In the 1980s, Pfizer invented a drug that aims to lower blood pressure and treat angina pectoris.

Unfortunately, the results of this new drug in clinical trials are very disappointing.

It neither relieves chest pain nor lowers blood pressure, and is an absolute failure.

However, when Pfizer was about to give up research on the drug, drug experiment volunteers reported a shocking side effect...

A generation of magic medicine was born here.

With this invention, Pfizer made a lot of money, and the patent for this drug did not expire until the beginning of the 21st century.

The emergence of similar products produced by Baiyunshan Pharmaceutical and other companies has caused Viagra's profits to decline.

"Your Majesty, you are right to say that, but the use of rubber is becoming more and more extensive, which means that the price of rubber will continue to rise.

Will this attract many people’s dissatisfaction?”

"What are you up to you? Rubber is a new thing after all, and it has not yet formed a close relationship with everyone's daily life.

Even if the price doubles a few times, it will not affect the lives of ordinary people."

In order to stimulate everyone's enthusiasm for going to sea and stimulate everyone to go to Southeast Asia to plant rubber, Li Kuan is no longer able to spare his efforts.

"It was originally like this, but the appearance of rubber rubs has something to do with more ordinary people. If scholars buy a rubber rub, it will cost more than ten cents, which will be a bit exaggerated.

If the price continues to rise, it will even be even more expensive."

"Everything will turn out to be the worst, and the price of rubber will eventually drop."

...

Papermaking has a development history of hundreds of years in the Central Plains.

From the Eastern Han Dynasty to the Wude period, a complete industrial chain had basically been formed.

However, the price of this papermaking is still high.

Until Li Kuan appeared, he waved the butcher knife of the price and cut it in half, then continued to cut it in half.

Nowadays, the price of paper has become much more affordable.

Although the price of these papers is still very expensive compared to the income of ordinary people, it has been considered a huge improvement.

Before papermaking technology is new, it is very difficult to further reduce the price of paper.

"Uncle Liao, you are back."

In the large yard of the Liao family, Pan Jing, who had just returned from school, greeted his landlord politely.

The Liao family is actually not short of this amount of rent. Liao Zhang is now the leading female shopkeeper of the King of Chu Mansion, responsible for the wool workshop.

However, Uncle Liao, who is used to not waste, still habitually rents out the excess house.

At that time, Dongfangping, the tenant, gave Uncle Liao a very big impression, and this is also the person with the highest official position he actually came into contact with.

This new tenant, Pan Jing, also left a very deep impression on Uncle Liao.

His Aye unfortunately died of illness a few days ago, and spent all his money at home, but the illness was not cured.

Even my own yard was sold.

In the end, Pan Jing lived a hard life with his mother.

Every day, I rely on Aunt Pan to make some money to wash clothes for neighbors.

Although the winter in Chang'an City is not as cold as Liaodong Road, it is definitely a cold area.

Every now and then, the water can turn into ice.

In such weather, it is natural to say that the hard work of washing clothes for people is not to be mentioned.

Fortunately, Pan Jing is also very successful. Although she is only nine years old now, she is very sensible.

"Come on, Pan Jing, I'll give you a gift. I heard that this thing can wipe the handwriting you wrote on paper with a pencil and continue practicing calligraphy.

In this way, you don’t have to practice calligraphy against the sand in the yard every day.”

Uncle Liao took out an eraser from his arms and handed it to Pan Jing.

"Thank you, Uncle Liao!"

In the past, Pan Jing would never receive gifts from others easily.

But what Uncle Liao said was so attractive to him.

He had no way to refuse to accept it.

"There is nothing to thank for, it's only a few cents. I hope you can study hard and enter Guanshishan Academy smoothly in a few years and become a knowledgeable scholar."

Although Uncle Liao is now considered a person who knows the words and snippets.

But it is only limited to identifying and judging words.

No matter how many things he had, he would never be able to learn.

He was quite looking forward to this tenant.
