The Head of the Ming Dynasty Spared His Life

This is a calculation battle between the top mathematicians representing Ming and the West.

Who will lose and who will win?

Although Descartes was swayed by Yan Song, this kind of calculation is still within his business scope. He is still full of confidence, and he glanced at Cheng Dawei provocatively.

Yan Song gave the two other tools such as straw paper and a pen, and gave an order: "Start! The one who calculates correctly wins, and if all calculations are accurate, the one with the fastest speed wins."

With the same drawing, more than 30 skilled accountants invited by Yan Song from the Ministry of Accounts were also calculating in the back hall.These people are responsible for working out a final number to determine who wins and who loses.

Descartes immediately threw himself into the calculation.

He is the king of analytic geometry, so he naturally has a unique set of calculation methods.He is unique. By simplifying the engineering design into a large graphic structure, he can easily simplify the huge city of Tianjin into geometric figures, and then use the more precise calculation of the material usage to quickly calculate the approximate usage.

This is the idea of ​​analytic geometry.

In fact, for Yan Song, it is not necessary to be particularly accurate to a specific piece or two of materials. He only needs to be accurate to a hundred units to grasp the approximate demand for the project.

It took Descartes less than an hour to complete the analysis of the Tianjin New City project and transform them into more than 1000 large geometric figures.For example, the city wall was transformed into a square by him, and the approximate required materials were calculated based on the average material requirements of each section of the city wall.

Although he was a little tired, he thought he had the chance to win!

He is the only one who possesses such advanced analytic geometry in the whole world......

He looked up, wanting to see the progress of his competitors.

Seeing this, Descartes almost vomited blood.

It turned out that Mr. Cheng was holding an abacus in each hand, and he was making quick calculations with his bows crackling left and right.

That speed is simply dizzying.

"Abacus?" Of course Descartes knew of the existence of this thing, but he didn't find it very convenient.

"I use analytic geometry to defeat your abacus."

After taking a look at Cheng Dawei, Descartes knew that he had encountered a strong enemy this time, because the latter was too proficient, and his calculation speed was extremely fast, and the abacus beads rang together.

Hai Rui and the businessmen of Daming were also amazed.

Because without comparison, there is no harm.

They deliberately ran to the back hall, where more than 30 accountants were calculating together. After comparison, they found that although Cheng Dawei had only one person and two abacuses, it seemed that his progress was faster than that of more than 30 people combined. Quite a few!

You are indeed the author of "Algorithmic Tradition" and the inventor of the tape measure.

Descartes, too, felt threatened, and he went all out, using analytic geometry, to speed things up.

Yan Song sat aside with a smile, drinking tea while leisurely watching Descartes and Cheng Dawei in the contest.

No matter which one of you is more powerful, it is still mine!

Haha, 2.9 is mine.

To get a top mathematician like Cheng Dawei, Yan Song already considered himself very lucky. He never expected that the Western Holy See would be so powerful that they would even tie up the founder of calculus!

Two of the top mathematicians of the time are working under their own accounts at the same time, so they still worry about construction?

These are two science supermen.

The businessmen on the scene are also masters of arithmetic, after all, they deal with numbers all day long.Several people also tried to calculate the amount of materials, but soon discovered that this was an impossible task for normal people.The materials for the construction of the entire city are too huge.He could only give up with a wry smile, and looked at the two adoringly.

Not long after, sweat dripped down Descartes' forehead.

After an hour, Descartes laughed out loud, dropped his pen and shouted, "I figured it out!"

At the same time, Cheng Dawei stood up and handed a piece of paper to Yan Song.

Everyone was amazed.

Both sides turned in the papers at the same time.

Yan Song smiled so much that he took the papers from the two, and said with a smile: "It's been hard work! Sit down and have a good rest."

Descartes ate the watermelon. Although he admired Cheng Dawei's calculation ability, he had greater confidence and urged Yan Song to judge the paper as soon as possible. Who is more accurate?

Yan Song glanced at the calculations in the back hall, and was speechless for a while.

There are more than 30 accountants, and only half of them are counted.

So, everyone waited for another hour, all impatiently waiting, and finally the accountants finished their calculations.Since they are division of labor and cooperation, one by one actuarial calculation, so more accurate and reliable.

Yan Song put the three papers together, so everyone could see clearly.

The answer given by the accounting gentlemen is that the construction of Tianjin New City requires ** tons of reinforced concrete.

More than 1 million tons!

It can be seen how huge a project Tianjin New City is.

Yan Song silently calculated in his heart, almost.

In fact, he did not intend to complete Tianjin New City in half a year.

Jiajing's imperial decree clearly stated that "100 million taxes must be paid in half a year." As for how Tianjin's construction is going, Jiajing doesn't care.Therefore, it only takes half a year to complete the construction of the port and the necessary market, without affecting the collection of tax money for Jiajing, it will be fine!

The prince and his gang are stubborn, but Yan Song will not be as stupid as them.
