super wormhole

The girl yearned for the unknown world of arithmetic. She had received a good education since she was a child, but as a woman, she was destined not to take part in the imperial examination to gain fame, so she didn't spend too much time studying the Four Books and Five Classics.Instead, her interests lie in "miscellaneous studies" such as arithmetic, medicine, piano, chess, calligraphy and painting. "Mathematics" is also one of the six arts of a gentleman, and mathematics is also admired by scholars, but in a social environment where imperial examinations are paramount, no one is willing to work hard on it.

The girl studied with a gentleman who was good at arithmetic since she was a child, and she could hardly find anyone to communicate with in this regard until she was young.And after studying the Ten Books of Calculus, mathematics seems to have reached its peak, and there is no way to continue.

Until now, Li Hao has shown a wider sky in mathematics, and the girl is yearning for it. If Li Hao is not a young man, she would like to learn from a teacher on the spot.

The girl stood up, gave a blessing to Li Haoying, and said: "In Mr. Li's eyes, the problem of chickens and rabbits in the same cage is indeed the foundation. What Mr. Li said before is not arrogant, but the truth. The little girl lost, I would like to do as before." It is agreed to copy a poem for the young master, I don't know which poem the young master likes."

Li Hao looked at the girl with a smile, "Let's just write the song "Beating the Drum" in "The Book of Songs·Beifeng"."

"Okay, I'll write to you right now... huh? "Beifeng·Beating Drums"?" The girl's pretty face flushed all of a sudden, "You...you!" After speaking, she turned around angrily, and walked away like a gust of wind. All I could hear was the sound of fast and rhythmic footsteps on the wooden stairs.

"This girl is interesting!" Li Hao looked at the girl's back and said to himself, "It's just a joke, don't take it so seriously. Girls in the Northern Song Dynasty are too thin-skinned, maybe I'm going too far?"

"Ding Fu," Li Hao called the butler, and asked, "I just saw the Mo family's carriage parked outside the shop, did the little lady just now belong to the Mo family?"

"This old slave doesn't know either. I heard that Mo Shouyi has a daughter, but I don't know if it's the little lady just now."

"You send a smarter guy to follow and take a look, and be careful not to let her find out."

Ding Fu immediately arranged for a guy to go out, and he came back soon, confirming that the little girl got into Mo's carriage.

Li Hao rubbed his chin and thought to himself: "No way, is it really such a coincidence? This girl is Mo Fan's sister? strangeness."

Li Hao already realized that his joke was a bit too much. After all, the social atmosphere of the Song Dynasty was far from that of the main world, far less open than the main world.In the main world, it's normal for boys and girls to joke around, but it's too abrupt to tease and copy love poems when they meet for the first time here.

"Old Ding, I'm going back home. Go to Cui Jiya and talk to shopkeeper Cui, and rent that shop. It's best if you can negotiate a lower rent. It doesn't matter if you negotiate a lot. Sign the lease contract today." Li Hao this time The main purpose of coming out is to choose a location for the photo studio. Now that the shop of the photo studio has been confirmed, he can go back home.

Some trivial matters can be handed over to the housekeeper Ding Fu. If everything is done by oneself, how can there be time to practice the original force?Which is more important, making money or practicing the Force?The great achievement of the force is the goal that I pursue in my life.After the business gradually grows, we must slowly learn to delegate power.

After returning home by carriage, Li Hao went directly to the backyard.

Two sets of solar home power generation systems brought from the main world, one of which has been installed, and Li Hao's master bedroom has been powered on.As a student of the Department of Electronic Engineering of a polytechnic university, it is too easy to install wires.

The wires from the power generation system lead to his own study and then to a workshop in the middle courtyard of the house.A whole set of laser printing equipment in the workshop has been connected to the power supply, and there is a row of sockets left to charge the batteries of the digital cameras in the future.

As long as the photo studio shop is well decorated, the photos taken after the opening will be brought back here for printing.The guys prepared to train a dozen of them, six were in charge of photography, three were in charge of printing and compression molding, and the others were in the photo studio to receive guests and bring back the memory card of the camera every day for printing.

In addition, Li Hao also promoted a buddy named Hong Dashi from Qizhen Yibao Pavilion, and let him specialize in managing matters related to the photo studio.This Hong Dashi is 27 and [-] years old. In the previous performance appraisal, he had the highest sales volume and was promoted to the leader of a sales team.According to the latest daily statistics, the sales volume of his group quickly rose to the first place, and it seems that he has a certain management ability.

After a long talk with him, Li Hao felt that he was more flexible in mind, hard-working and capable, so he tried him out for a period of time, and if he was good, he would be the shopkeeper of the photo studio in the future.

When Li Hao returned to the study in the backyard, if a person from Song Dynasty saw the furnishings in his study, he would be very surprised, because they had never seen many things before.

There is a thin and light laptop on the desk in the middle of the study, and there are two printers next to it, a color inkjet printer that can print pictures, and a laser printer that prints extremely fast.

Next to the laptop is a pen holder full of signature pens, pencils, and pens, a file box, several file folders, a note pad, and a thick stack of 4 papers.In addition, staplers, rulers, paper clips, cross clips, glue, scissors... all kinds of stationery are placed in an orderly manner.This is almost moving the desk from the main world. [

Li Hao sat down in front of the computer. He admired the girl he met in the Qizhen and Yibao Pavilion just now. He lived in the Song Dynasty for a long time, and it was the first time he met such a beautiful woman.Recalling her shocked and admiring eyes, Li Hao thought it was a bit funny, so I will give you a small gift to shock you even more, and express my apology by the way.

After starting the computer, Li Hao thought for a while, and opened the folder named "Books", and there were rows of densely packed book titles inside.This was downloaded from a forum, and the poster advertised that "all the famous works of ancient and modern China and foreign countries are included in it".Books such as "The Wealth of Nations", "Mathematical Principles of Natural Philosophy", "Heavenly Creation", and "Compendium of Materia Medica" were swept away.

Enter the four words "geometry original" in the search box, search a bit, and a wor file will come out immediately.After skillfully opening it and converting it into traditional characters, Li Hao tapped "print".

The laser printer immediately hummed slightly and quickly spit out printed 4 sheets of paper.

Finally, I typed in the four words "Original Geometry" in a large font, and added a row of five small characters "written by Euclid".Print out this page as the cover.

After flipping through it for a while, I added some descriptions of mathematical symbols in front of the document, as well as the comparison between Arabic numerals and Chinese numerals.Print this page out and place it under the cover.

Li Hao didn't have a binding tool like a hot-melt machine, but he didn't need such an advanced tool. He drilled a few holes in the stack of paper, threaded it through with a thick thread, and it became a book.

In this way, a freshly released "Elements of Geometry" was placed on the desk.

This book is the most famous, complete and widely circulated mathematical work in the world, and its circulation is said to be second only to the Bible.According to the historical trajectory of the main world, this book was not introduced to China until the end of the Ming Dynasty. At that time, the famous scientist Xu Guangqi met the Italian missionary Matteo Ricci, and the two translated it together.It's a pity that only part of it was translated, and it took another 200 years for this famous mathematics book to finally appear in China in its entirety.

In other words, this great work of mathematics written by Euclid in 300 BC did not have a complete Chinese translation until 1857 AD.

If the "Elements of Geometry" is spread at this moment, it will be about 600 years earlier than the history of the main world.Ancient Chinese mathematics developed to the Song Dynasty, and there have been many specialized mathematical works, such as "Zhoubi Suanjing", "Nine Chapters of Numeracy", "Sun Tzu Suanjing", etc., but these books are really inferior to the development of mathematics. On "Elements of Geometry".

Li Hao took the book to the front yard, found a long-term worker, and asked him to deliver the book to Mo Fan, and hand it over to Mo Fan himself.

For the task assigned by the young master himself, how dare the long-term worker neglect it?More than half an hour later, Mo Fan took over the "Elements of Geometry" from the long worker.

Mo Fan flipped through the book, and was shocked again. He was shocked every time he saw something in the Rare Treasure Pavilion, which has almost formed a habit.He wasn't shocked by the contents of the book, he glanced at it briefly and knew that it was a book on mathematics, and he didn't do much research on it.He was surprised that the printed font was so small and so clear.

If this printing technology is used, the thickness of the Four Books and Five Classics will be reduced by more than four-fifths, saving a lot of paper.He touched the paper again, and found that the paper was thick and tough, and it was quite different from the paper on the market.

Mo Fan yearned for the country built by the descendants of Lu Ban in Li Hao's mouth. It really is a place where skilled craftsmen gather, and every item is so magical.

He took the book and walked towards the small building where his sister lived.

Mo Fan's younger sister, Mo Shiyun, was sitting in the gazebo in the backyard garden, and her personal maid advised, "Are you still angry with that person? Forget it, there's no need to be angry with that kind of resentment, it's good to be angry."

Mo Shiyun shook his head slightly and said: "I'm not angry, I was just thinking about how I can learn arithmetic from him. By the way, he called arithmetic mathematics. Well, number is one of the six arts of a gentleman. Mathematics, a very atmospheric title."

The maid was anxious: "He made you so angry, and your character is so low, why do you still want to learn from him?"

"The character is indeed very bad, but his knowledge is not bad at all. It is simply too advanced. He can be regarded as a master of mathematics. The hateful thing is that he wants me to copy "Beating the Drum", and I will avoid him when I see him in the future." gone."

The maid frowned and asked, "Which poem is "Beating the Drum"?"

"One of the poems in Beifeng in the Book of Songs, there are two lines in it: "Death and life are broad, talk to Zicheng. Hold your hand and grow old together with you." If I really copy these two lines of poems to him, I will still have the face to see him in the future. Human? It's too hateful!" Having said this, Mo Shiyun's pretty face flushed again.

At this time, Mo Fan's voice came from afar, "Little sister, so you are here, and I have been looking for it for a long time."

"Brother, why are you here! Aren't you going to study in the study at this time?".
