Two o'clock in the afternoon. Faculty of Mathematics Auditorium.

A thousand guests yawned for days, constantly drinking strong tea to force themselves not to fall asleep, and tried to concentrate on watching Hou Qiang talking eloquently on the podium.

It's so hard!

I don't understand it at all.

Ge Qingping was stunned the whole time, he couldn't even interject, and he couldn't bear to fall asleep.

Geometrically, a tangent is a straight line that touches a point on a curve. More precisely, when a tangent passes through a point on a curve, the direction of the tangent is the same as that of that point on the curve, and the part of the tangent near the tangent is closest to the part of the curve near the tangent. This is the infinite approximation of thought......"

"And I'm talking about the tangent problem that I found in my calculus research...... That is, infinitely close to thought. ”

“…… P and Q are two adjacent points on the curve C, P is the fixed point, when the Q point is infinitely close to the P point along the curve C, the limit position PT of the secant PQ is called the tangent of the curve C at the point P, and the P point is called the tangent point; The straight line PN that passes through the tangent point P and is perpendicular to the tangent PT is called the curve C, and the normal of the point P ......"

The audience was stunned.

Even Li Zhen couldn't help frowning, and even Li Zhen sounded a little laborious. He was simply surprised to the extreme, he just taught the basics of the Institute of Advanced Mathematics, but he didn't expect that during this time, Hou Qiang actually developed a new concept.

Infinite approximation of thought.

Tangent!

Li Zhendu was a little helpless, the apprentices of the church starved to death of the master. Sure enough, Hou Qiang's mathematical talent is really good.

After Hou Qiang's patient explanation and the use of many popular examples, this can be regarded as a blind spot for the vast majority of people on the scene. But I still don't know much about it.

Qian Mao exclaimed in his heart: "Is this the mathematics I know?" ”

"When did math become such a monster!"

"Oh my God, this is math?"

“……”

Hou Qiang is gone, and everyone can't understand it, but they just feel unclear......

The people from the Institute of Financial Mathematics are also on the field, and if you talk about the things of the Institute of Advanced Mathematics, they don't understand it at all. Then financial mathematics, they can finally understand a little bit.

But listening to it, I found that this Nima financial mathematics, the only thing related to life, was not understood.

The dean of the Institute of Financial Mathematics is named Liu Kaifu, who wears a sweater and walks around the podium calmly and confidently, talking eloquently.

"My name is Liu Kaifu and I am the dean of the Institute of Financial Mathematics. The results of my research today are mainly about economics. To name my theory, it should be defined as 'economies of scale'. ”

A thousand people in the audience looked at each other, they hadn't heard of it, they all knew the words, and they didn't know what it meant when they were combined.

"Economies of scale, in a nutshell: costs decrease as production increases. This is a very complex proposition, but it is crucial to the overall economic promotion of the country. ”

"The phenomenon of increasing economic efficiency through the expansion of the scale of production can be summed up in economies of scale. Economies of scale reflect the relationship between the concentration of factors of production and economic efficiency. The advantage of economies of scale lies in the fact that the long-term average total cost decreases as production increases. This is the main purpose of studying economies of scale, and by extension, we can understand the importance of economies of scale, and what people in government and business must understand......

…… It's not just that the bigger the scale, the better, because economies of scale are about the scale of production that will make the best economic benefits. Once the company's production scale expands to more than a certain scale, the marginal benefit will gradually decline, or even fall below zero, or even become negative, causing diseconomies of scale......"

It's a matter of money.

All the businessmen present pinched their jaws and forced themselves to cheer up and listen. Going around and around, everyone was confused.

Dan Zi said; Sleepy and learned, sleepy and learned.

Businessmen want their businesses to become bigger, so they have to listen hard and learn hard. Fortunately, as Liu Kaifu said from shallow to deep, everyone can understand something that is half-understood.

Then, there is the proposition of the Institute of Statistics.

"The importance of statistics is self-evident, and a deep understanding of statistics is of great benefit to the whole country. Understanding the national big data is like a sword in the hands of the imperial court. The imperial court will know the data of all the places in the country......

And what I found was extrapolative statistics. This is a new theory and assumption proposed by the Institute of Statistical Mathematics, and it is also a new branch of statistical application......"

When it comes to statistics, it's much simpler. The officials of the imperial court all pricked up their ears and listened. It's amazing, extrapolating statistics, it's a new concept for them. That's pretty much the whole country.

And the bosses of those big companies are also serious, this can be said to be the only one in the mathematics department who can understand, right?

"Inferential statistics is a method of studying how to infer the quantitative characteristics of a population based on sample data, and it is an inference in the form of probability on the unknown quantitative characteristics of a statistical population on the basis of the description of sample data......

“……”

Finally, the competition in the mathematics department is over.

A thousand guests walked out in silence, silent, honey silent.

Unlike the noise coming out of the chemistry auditorium, no one could say a word when they came out of the math auditorium.

At this time, everyone felt that their heads were numb.

That night, sponsored by the Kyushu Academy of Sciences, two books appeared, "Kyushu Science and Technology Award Chemistry Nomination" and "Kyushu Science and Technology Award Mathematics Nomination".

A total of 50,000 copies were photocopied and distributed to all those who did not enter the territory of Laoshan.

Not only Kyushu, but also the Yamato version, the Baipao Chinese version, the English version, and the Rakshasa version have been compiled through the translation of foreign language experts in the liberal arts.

When 50,000 nominations were placed at the door of the Kyushu Academy of Sciences, the whole Laoshan went crazy.

"Ah, it's been announced!"

"Quick, Sawagi, get me a copy of the Yamato version."

"I didn't expect the Kyushu Academy of Sciences to do this, which is simply beneficial to the country and the people. Let scientists all over the world know about the birth of new scholarship. ”

"These are two nominations for Rakshasa language, a nomination for chemistry and a nomination for mathematics. Quickly send it back to the Rakshasa country, make a copy, and distribute it to all the scientists in the country who have not come to Kyushu, and the era of academic explosion is coming. ”

"Quick, take the fastest boat and send someone back to Yamato. Many scientists in Yamato Province are still waiting, and they will be copied immediately after returning to Japan and distributed to scientists in Yamato Province for free. The Kyushu Academy of Sciences is free of charge, and we can't charge a fee either. ”

"This is the crystallization of wisdom!"

"From the Kyushu Academy of Sciences, I saw the hope of a big bang in science."

"Maybe from now on, we humans today will never need to dig up ancient ruins again."

PS: Not happy. The monthly ticket list was originally a good seventh place, but today it was completely blown up by others and became the eighth place. And the ninth place and I are only a dozen monthly passes, and I may be blown up again tomorrow.

Within two days, the monthly pass will drop two places in a row. Unhappy...... Slightly.

The new book recommended by a good friend, no one reads it. Woowoo......

There are no official recommendations, no new readers to join, and many readers like to keep the book. Madan, the number of subscribers is also starting to fall.

That's right, I'm just going to complain. I'm just going to complain.

Getting back to business, so today there are two more.
