Chapter 178 The Double Power Law Solution for Linear Algebra

Sun Jing's change caused many scientists present to look sideways.

However, gradually.

The sound of "Hua Hua" was heard continuously in the entire meeting room.

However, there are dozens of very old mathematicians who are proficient in mathematics, or physicists who are involved in mathematics.

He snatched the paper and pen from Chen Ming, and surrounded the whiteboard podium.

A group of people stood behind You Wenwen, staring at the words, numbers, and symbols on the whiteboard with wide eyes.

With a tense face, he started to write on paper with a pen, or with his hands.
Surprising!

An extremely strange atmosphere fell into the entire conference room.

Chen Ming and several cadres in charge of hosting the proposition meeting kept stepping back, making way for more and more scientists who surrounded the podium.

A few old professors headed by them are Long Guo scientists who have devoted their lives to researching mathematics.

An unprecedented shock in a quiet afternoon.
Being squeezed out, Chen Ming and his colleagues looked at each other in horror, not knowing what happened.

I can't understand what is written on the whiteboard!
silence.

silence.

In the deathly silence, Zhou Gangde let out a hysterical roar:

"Can you stop blocking me, I can't see the whiteboard!"

However, everyone present had no time to pay attention to him.

At this moment, everyone fell into a magic barrier.
Zhao Changxun and Zhou Gangde were helpless, they climbed up the chair anxiously, stood on the chair, looked at the whiteboard, and continued to write on their hands.
Most of the people in the conference room are Long Guo, who is one of the best researchers in mathematics and physics.

Zhizhi has been immersed in the research in the field of mathematics for many years, and has experienced experience.

How can he look up to a female class like Ju Wenwen.

But today
Chen Ming looked at a group of stunned old professors surrounding You Wenwen in confusion.

He couldn't understand the numbers and mathematical symbols that appeared on the whiteboard, but he followed the expressions of the most cutting-edge scientists in the field of mathematics.

It should be enough to shake the achievements of contemporary mathematical science.

That's right!

Mathematics is an amazing subject.

There is a saying that describes the mathematics circle - high IQ club!
Only people with real high IQs can experience happiness in it.People who don't understand will never understand that kind of happiness.
Close the pen.

With a "click", the cap of the whiteboard pen was covered.

Ju Wenwen turned his head and looked at the dozens of people standing stupidly under the podium with a confident smile:

"Hello, uncles and grandpas. This is the quick solution algorithm I invented."

Whiteboard:
Example:

f(x+y)=f(x)+f(y)

Every linear space has a basis.
For a non-zero matrix A with n rows and n columns, if there is a matrix B such that AB=BA=E (E is an identity matrix), then A is a non-singular matrix (or invertible matrix), and B is the inverse of A
A matrix is ​​non-singular (invertible) if and only if its determinant is not
A matrix is ​​positive semidefinite if and only if each of its eigenvalues ​​is greater than or equal to zero.
but.
x and y can be functions or differentials.
f can be polynomial or differential.Here I abstract them into a symbol, an expression, or a type of matrix. Together, they satisfy the final linear relationship: f (x+y)=f (x)+f(y).
silence
Everyone, silence!
An eerie silence.

Deathly silence!

沉默1秒、2秒、5秒.1分钟、2分钟、10分钟
For a full 10 minutes, no one spoke, not a single sound was heard.

The whole floor was silent.

Chen Ming and Chu Ran are the cadres of the Longguo Education and Research Center, and they were specially selected by the proposition committee to help advance the competition proposition meeting.

Organize with subsequent test questions.

The two are not scientists in the fundamental sense, and there is still a certain distance from the level of scientists in the field of mathematics or physics in this room.

Standing at the end, Chen Ming couldn't understand what You Wenwen wrote on the whiteboard.

This is surprised to see that scholars and scientists from all walks of life who were previously as high as the sky, actually all showed the look of longing like a pilgrimage below.

The two looked at each other and made eye contact.

There is only one reason for this strange scene.

That is!
The mathematical research results written by Ju Wenwen on the whiteboard are absolutely unprecedented.

After hundreds of years of development in the history of mathematics, it has never reached a height that no one has reached!

It would be terrible if someone passed by the door of the highest conference room of the Longguo Education and Research Center right now.

You will never realize that there are dozens of Long Kingdom scientists sitting in it!

For a long time.

The gray-haired old man, who was also the first scientist to stand up against Juventus before, Zhou Gangde walked out of the crowd.

Taking a deep breath, he said in a trembling voice, "Ms. You is a genius, I was wrong."

The old scholars who didn't like Juventus at all before couldn't help but feel the burning shame on their faces.

If a math genius like You Wenwen is not accomplished, then all the so-called scientific circles here are not worthy of appearing in the competition proposition group!

You Wenwen nodded and smiled easily: "It's okay, Grandpa."

Zhou Gangde blushed: "What is it called?"

After the words fell, everyone turned their heads to look at Juventus.

Ju Wenwen took a deep breath, his eyes were calm, and he said word by word:

"This is my invention."

"—the double power law solution of linear algebra!"

Double power law solution for linear algebra?
When most of the audience heard this term for the first time, their faces were full of confusion, and they couldn't understand it.

Well known.

At the very beginning, mathematics was classified internally.

Because the mathematical system is too large and complex, it has been studied to the level of this group of contestants and scientists.

There is not so much energy to study all dimensions of mathematics.

For this reason, mathematics is also divided into geometric mathematics and algebraic mathematics.

Geometric mathematics is divided into plane geometry and solid geometry, and algebraic mathematics includes micro algebra and macro algebra.

Of course, the current classification of mathematics research fields is not perfect, and the world's research on mathematics is still at the bottom of the pyramid of truth.

This is where the difficulty of this subject lies. Otherwise, why does mathematics in primary and secondary schools stump a group of students every year?
Let's talk about the brand-new tools of linear algebra that Juventus gave on the whiteboard.

It can be said that in the whole room, there are people who can understand this whiteboard wall.

Very few!

Zhang Tengyue, who knew a little about algebraic mathematics, asked a question:
"We know algebra, but what does this linear algebra mean?"

After the question was asked, everyone in the audience pricked up their ears and listened. Ignoring the shame of Ju Wenwen's criticism before, the desire for knowledge from the bottom of their hearts urged all the old people to ask Ju Wenwen for advice.
