Don't be afraid, this time the two-way foil is in the hands of civilization别怕，这一次二向箔掌握在文明的手中

Just because Li Haoshi, an entertainer on the Xiaoguo talk show and nicknamed HOUSE, joked about vulgar jokes that offended our people's soldiers, the netizen who uttered a few words of his heart on Weibo has now been arrested by reactionary forces, overseas The three forces of power and hostile forces have been targeted. The cry of righteousness he uttered in the field of public opinion aroused thousands of waves, but in the end unfortunately exposed his coordinate position in the dark forest.

1. On a battlefield without gunpowder smoke, the struggle is as cruel

Today, our netizen has been "opened" by some cockroaches and maggots on foreign public opinion platforms including Twitter and Telegram. The so-called "open box" refers to our personal information, including but not limited to real name, ID number, home address, kinship, work unit and social network, etc., after being obtained by criminals through black means, it is made public on the Internet .

Once we are "opened" by criminals, it means that we are running naked in the vast information world. Next, not only our social accounts will be focused on by the "three forces", targeted attacks, repeated flooding, and long-term reports, but also our mobile phone numbers will be blacklisted by them, followed by all kinds of unsightly The endless bombardment of harassing text messages with the purpose makes you unable to eat, work well, or sleep well, making your mental pressure in a state of high tension all the time, until your mind is overwhelmed. That string inside snaps and drives you crazy, maybe even to death.

Because our home address has been exposed, we may still receive various "kind greetings" and "surprise surprises" from the "three forces" in the future. If something looks disgusting, dirty, or scary, they will pick it up and send it to you. Unwrapping a package should be something to look forward to, but when your coordinates are exposed in the dark forest, you never know whether the next package you open will contain flowers or shit, a dress or Shroud, is it a cake or a cockroach. When you understand that in the next second there may be a cold shot from nowhere to stab you, you may no longer dare to order express delivery, no longer dare to order takeaway, or even no longer dare to go out.

Because our work units and connections have been exposed, not only us, but also our parents, our lovers, our children, our friends, our colleagues, and even Netizens who meet by chance in the Bo world may be targeted by the offspring created by the "three forces". Then, the reproductive son will use the methods I mentioned above that were originally aimed at us personally, and do the same on them.

Why do I have such a clear understanding of these things, and can do so well? Because I, like that Weibo netizen, have long been unboxed by the "three forces" on various social media at home and abroad. And my box was opened more thoroughly. If other people who were targeted by the "three forces" were streaking on the Internet at best, then I can be said to have been X-rayed by them, seen with a gastroscope, Cut with a lancet. And this is just a process, not a result, it is only in progress, not in completion.

2. Good people are being pointed at by guns, we cannot stand idly by

Some comrades, friends and loyal fans who have been paying attention to and supporting me for many years should know that the frequency of my content before was actually not as high as it is now. There are several articles and videos a day, and it is often a long speech. Because in the past, apart from self-media, I had my own job. I have been doing this job for a long time, but in the end I chose to resign.

This is not because I have any dissatisfaction with this job, nor is it because I think that I can earn more by saving time and energy for self-media, but because I am already a person who has been opened. The coordinate location in the dark forest has been exposed. The hatred of the "three forces" towards me is deep-rooted, and the sons have been entangled with me for a long time. I'm a copper pea, it doesn't matter how they steam me, boil me, hammer me and fry me, but I can't watch the people I work with suffer because my city gate is on fire, so I finally choose Don't cause this trouble to your colleagues, just concentrate on going home and being an aunt.

It's hard to say whether this result is what the progeny who are still creating countdown phantoms on my irises, and the "three forces" who are hiding behind the scenes or manipulating or instigating the procreation expect. You want to say yes, my original job has been lost under their repeated tossing, I lost an independent source of income, and became a family that basically can only rely on rewards and bringing goods to subsidize the family Women; but if you want to say no, I have more energy now, I can publish more and longer articles and videos, and I can pour more ammunition on the reproductive son and the "three forces" than before .

Moreover, it was only after I was forced to this stage that I finally figured out the truth: in different stages of life, the scenery we see is different. No matter what mood we embark on the journey at the beginning, whether it is love or love, disgust or indignation, when we have traveled far enough, it is normal to encounter gusts of wind and rain, lightning and thunder. After all, how can such a long road be sunny and sunny?

If it was just a strong wind of magnitude 7 or 8 and rainfall of tens of millimeters, many people might still be able to bear it, but what about a typhoon of magnitude 10 and a rainstorm of hundreds of millimeters? At this time, some people may be about to retreat, and I feel the same way about this, and I think everyone who is watching this issue can also empathize with each other.

It is not difficult to know what has happened. I am also a person who has been raped by the Internet. I know what kind of inner suffering and self-doubt a person will fall into after experiencing such sudden life changes. Therefore, retreating bravely at this time is not an escape, but a strategic retreat for self-protection. Saving people is much more important than saving land, and such a trade-off is completely reasonable. No matter which friend has exposed the coordinates in the dark forest, no matter whether you stay away from cyberspace temporarily or for a long time for any reason, I will understand, respect and support your choice.

However, understanding is not enough. At this moment, my mood is the same as that of Yu Zecheng in "Latent" after discovering that shopkeeper Qiu, the liaison officer of the Tianjin underground transportation station, was arrested by the military commander. Shopkeeper Qiu was tied to the tiger bench in the interrogation room of the military command, and was tortured by the Kuomintang secret agents to the point where he was already inhumane. Looking at this scene again, Yu Zecheng couldn't help but burst into tears.

Listening to Shopkeeper Qiu's selfless consolation of "Don't dream, no one can defeat my faith. I can die, but I will never betray my warrior"; seeing him would rather fight I tried my best to bite off my tongue, just not to implicate the fearless demeanor of other comrades on the front line. I felt that my chest was the same as Yu Zecheng's, and there was a rush of blood rushing out of my chest. Yu Zecheng didn't stand idly by the comrades who were trapped in the tiger's mouth, and I couldn't allow myself to hang up like this. I also had to do something for our shopkeeper Qiu.

3. Don't be afraid, this time the two-way foil is in the hands of civilization

Therefore, I decided to solemnly broadcast another plaintext broadcast to the vast dark forest in the field of public opinion. Listen up to all the broods who are still trying to find ways, all kinds of evil, and the organizations behind them, as well as the forces behind them.

I know that in your eyes, we are still nothing more than insignificant bugs. You will still hide behind the monitors, mocking us secretly, contemptuously thinking that your behavior of humiliating or even destroying us has nothing to do with us. But after experiencing all kinds of blindfolds you have created over the years, such as phantoms on the retina, such as the flickering of the cyberspace, I have now realized the law of the dark forest in the field of public opinion, that is, compared with us, the group of bugs Come on, you guys who claim to have all the initiative and think that I have the advantage are actually more afraid of revealing your own coordinates.

You have never dared to stand up and show your true colors to others, presenting facts, reasoning, judging justice, and arguing logic with us. You will only be like rats living in the sewer, and only dare to come out to scare people when night falls. If it weren’t for the software and hardware support provided by the Trisolarans, the continuous flow of U.S. dollars, Japanese yen and New Taiwan dollars donated by them to maintain your livelihood, and the remote assistance and technical guidance provided by them, facing us, we would treat all of you If any individual is picked out alone, I think it will probably be more afraid of our group of bugs.

Your organization, capital chain and technology tree level are obviously higher than ours, I have no doubts about this. But then again, isn't your sense of superiority only used to bully us little bugs? In the face of a higher civilization with higher technology, larger organization and stronger power, the offspring you are proud of, whether it is water droplets, are they nothing?

Obviously, you don’t have two-way foils and light particles in your hands, which are real dimensionality reduction strike weapons. You have already mastered my coordinate position. If you have this kind of creation that can subvert cognition, you can still Make me gasp in the cyberverse for so long?

Not only have I seen the power of two-way foil in the Cyberverse, but the ones that were flattened by it were not us bugs, but those who made vulgar jokes about the soldiers among us bugs, who thought It's just the so-called higher creatures who are with you all the way and always feel that they also have fly swatters and insecticides in their hands.

Compared with our group of bugs, these guys who can tell a bunch of people a few funny jokes and earn tens or even millions of dollars may feel that they are qualified to call themselves higher creatures, but so what? Once the two-way foil is unfolded, it can cover more than 9.6 million square kilometers, and it can clear the 8-figure wealth in one go, and it can also take pictures of those guys who have always been high in the past into two-dimensional creatures.

is it scary? Maybe it is for you, but I, the bugs, just feel lucky that a powerful weapon like the two-way foil is lucky to be in the hands of civilization this time.

I know very well that the reason why you concentrated on attacking the netizen who exposed the despicable behavior of these higher creatures is not because you sympathize with them, nor because they have any interests with you. Because discrediting us, alienating us, dividing us, and even instigating us to attack each other, luring us to set ourselves on fire, and deconstructing our grand narrative is what you guys have to do when you get paid.

We may be worms, but you are nothing more than turkeys in the dark forest, and you are even more afraid of revealing your own coordinates than we are. Because our exposure will at best lead to cyberbullying. We received a few harassing text messages and received a few embroidered shrouds. What about you? If you are exposed, not only will you have to face thousands of fines, you may also have to bear a heavy prison sentence, and you will even have to count the serious sins you committed in the first half of your life behind bars for the rest of your life.

Of course, there are also some of you who think that you can sit back and relax because you are not in mainland China, and you can continue to eat your braised pork rice, tempura, and hamburger fries with peace of mind. For this kind of thing, I can only say: I wish you all can integrate into the new circle of your own choice, don't be shy to ask our overseas agencies for help when you are wronged outside, and don't go to social platforms to use Simplified Chinese Complain in Chinese, let alone sneak over with your tail between your legs because you can't get along outside.

Because I've seen too many of these things. A lot of sons think that if they reach Trisolarans, they are masters, but they never think about it. In the eyes of Trisolarans, they are just tool people from beginning to end. Even if you are reproductively isolated from the locals, I wouldn't be surprised. I don't believe that there are so many fools on the Trisolaran planet who can really empathize with a group of turkeys.

To be a tool person requires the consciousness of being a tool person, whether it is inside or outside the country. 14.5 million NT dollars is not so easy to get, these are the money used to buy conscience in the real sense. When the hearts, livers, spleens and lungs are all dug out by Trisolarans, the day you, turkeys, will be slaughtered will not be far away.

Conclusion, insist on the truth, even if the lie becomes angry from embarrassment

Today's topic was caused by the netizen who bravely exposed Xiaoguo's vulgar jokes that offended the soldiers, because his personal information was dug out by the "three forces", and then he was brutally targeted and persecuted. Combining some of my personal experiences in the past, I expressed some personal feelings, and I have the courage to broadcast again to those monsters and ghosts lurking in the dark forest.

Speaking of which, it’s almost the same, but I always feel that there are still things on my mind, so at the end of today’s content, I want to share with all fans, all friends who care about and support me, and all those who are willing to help us all. Comrades who solve the problem of being scolded, say a few words from your heart.

Marshal Chen Yi said that the victory in the Battle of Huaihai was pushed by the people with small carts, and the struggle on the battlefield of public opinion is actually the same. There may be no gunpowder on this battlefield, but all the fighting here is equally cruel. Solving the problem of being scolded has never been just a matter of the official government and the mainstream media, just like the War of Resistance Against Japan and the War of Liberation, it was not just a matter of the Eighth Route Army, the New Fourth Army, and the People's Liberation Army. Only when the masses of the people are fully mobilized, participated, and actively participate in this arduous and glorious cause, can we hope to win the final victory.

What does it mean that the people are the masters of the country? For ourselves, for our friends, for our family, for the tens of thousands of toiling people who are struggling in different positions to support the normal functioning of this society, and for the people's soldiers who stand on the border day and night with steel guns in hand to protect the lights of thousands of families, For our ancient country, which dates back to 1840, countless revolutionary martyrs and people with lofty ideals sacrificed their heads and shed their blood to gain rebirth from the ashes. Today, everyone can stand up and speak out bravely, defend the truth, stick to the moral bottom line, and stand up to the ugly Struggle against lies tenaciously, this is the people being the masters of the country.

What is democracy? Can the definition of democracy be reduced to a ballot game in the narrow context of the West? No, democracy is not supposed to be like that. When the people are the masters of the country, it is democracy. When the people are the masters of the country, it is democracy. When the people are the masters of the country, it is democracy. Democracy is not only a right, but also an obligation. As long as it concerns all of us, the collective, and the Chinese people, we should stand up, do things that can do things, and speak out for those who can speak out. If there is a little heat, it will emit a little light, so there is no need to wait for the torch. Even if there is no torch, we can rely on our own people to collect firewood and create our own light in the darkness.

I am just an ordinary Chinese aunt, but I can also use my way, my efforts, and my persistence to do what I can for our collective. They hit theirs, we hit ours, and they are not the only ones who know how to deconstruct. Who says shrouds can’t be dresses?

Don't think that the sky is falling and justice in the world no longer exists just because of the phantoms on the retina and the flickering of the cyber universe. The first impression a lie leaves on us is often the pretended truth. Insisting on the truth does not always mean that we will reap flowers and applause, likes and rewards, cheers and praises, but it may also be cold shots and back arrows, abuse and humiliation, harassment and threats.

Adherence to truth often means contempt for lies. The more we don't believe it, the more easily it becomes angry. When it gets angry, it will show its true colors, and when it tears off the painted skin, it will open its bloody mouth to us.

so what? Let the curse they weave out of lies, why not make it bigger? As long as the belief in the truth is strong enough, what our ears hear is the hymn to the brave.

A commenter said "why not look into how to make 2D foils".

Today, let’s put aside the TV series "Three-Body Problem" for the time being, talk nonsense about our own understanding of the two-way foil, and briefly analyze the mathematical prototype and attack principle of the two-way foil.

And from the perspective of war, see if the human beings on the earth already have a strike method similar to the two-way foil, and explore the measures to crack the two-way foil.

01 What kind of super weapon is the two-way foil?

The two-way foil is a dimensionality reduction strike weapon that appeared in "Three-Body III: Immortal Death".

In the third part, a spaceship from the singer's "mother world" launches a piece of two-way foil, which instantly makes the solar system two-dimensional, and all life in the solar system becomes a painting.

According to the introduction of the original "Three-Body Problem", the two-way foil looks like this: it is a specially processed two-dimensional space, 8.5 cm long, 5.2 cm wide, and has no thickness. (Reminder, thickness does not mean it must be two-dimensional!)

The two-way foil is bound by a special force field in the package state, which can be preserved forever, showing a crystal clear transparent paper sheet, and in the standby state, when the package force field gradually dissipates, it will emit soft white light, which looks like a A completely harmless two-dimensional film, and fly to the destination at the speed of light.

After the two-way foil reaches the three-dimensional space, all three-dimensional substances that touch the two-way foil will be two-dimensionalized, that is, everything will become a thin sheet with no thickness, and some three-dimensional details will appear.

After reading the introduction of the two-way foil, the audience who have studied "Linear Algebra" and "High-Dimensional Statistics" (or Multivariate Statistics), do you feel familiar with the principle of the two-way foil and the "linear algebra" in "Linear Algebra"? Flat matrix" is not very similar?

Is it very similar to Principal Component Analysis (POA), Principal Coordinate Analysis (PcOA), and Multidimensional Scaling (MDS) in "High Dimensional Statistics"?

Is it similar to the tSNE nonlinear dimensionality reduction algorithm in single-cell transcriptomics (including spatial transcriptomics) and the UMAP dimensionality reduction algorithm?

02 Today we combine the two-way foil to briefly introduce the "flat matrix"

A "flat matrix" is a type of matrix that can perform compression or dimensionality reduction operations on space.

Audiences who have studied "Linear Algebra" probably still remember that a matrix is a transformation (or a mapping) that maps the transformed object to a new space (or coordinate system), while matrix multiplication is a specific linear transformation.

For an M*N matrix, if M=N, the matrix is a square matrix. For a square matrix, a 2x2 reversible square matrix represents the reversible transformation of a two-dimensional space; a 3x3 reversible square matrix represents a three-dimensional space transformation.

But for a non-square matrix, if an M*N matrix, if M<N, then it is a "flat matrix, if the number of rows M of the matrix is 2, and the number of columns N is 3, the transformation it performs Similar to the dimension reduction blow of the two-way foil, under its effect, the transformed object is flattened, compressed from three-dimensional to two-dimensional, and at the same time, part of the information is lost during the compression process.

Tell me, is it a bit similar?

There is one more thing. Everyone knows that the earth is a planet similar to a sphere, which is three-dimensional, while the world map we commonly use is two-dimensional. If the three-dimensional globe is made into a two-dimensional map, is it similar to a two-way foil? The dimensionality reduction strike principle?

The three-dimensional earth becomes a two-dimensional map. In the expression of spatial distance, multi-dimensional scaling method is often used, which is commonly referred to as "approximate geodesic distance with Euclidean distance", or in other words, it is a display in low-dimensional space. Multivariate data analysis techniques for high-dimensional spatial "distance" data structures.

From this point of view, the principle of two-way foil technology can not only be used to destroy the "lower" civilization in the universe, but also serve the survival and development of civilization.

For principal component analysis, principal coordinate analysis, tSNP, UMAP, and their similarities with the two-way foil, you can review the knowledge you have learned or find some materials to study and compare yourself, so I won’t be long-winded here.

03 Are there two-way foil weapons on the earth?

nothing now!

However, the dimensionality reduction attack principle of the two-way foil can be said to have existed and been used on a large scale for a long time on the earth.

It is said in "Three-Body" that the two-way foil has no thickness, only length and width. In fact, we can understand space and dimension from another angle.

"Space" is not some kind of container (such as the former ether theory), "space" is the free state of the existence of things themselves.

And "dimension" is a certain characteristic or ability of a thing, and "dimension" is a measure of a certain characteristic or ability of a thing.

When understanding "measurement", understand "nothing" and "nothing" as "relatively small", rather than nothing, otherwise, when explaining the "two-way foil-like" weapon system on the earth, you will fall into a word-cutting debate Falling into the absolute black hole and unable to get out.

We all know that naval battles in history were all carried out at sea level, and both sides could only fight with artillery at visual distance, so the masts of warships were all built very high, so that the enemy could be spotted and fired first. .

For this plane, it cannot be understood as having no height, because it is relatively low, and it is a "plane" for a higher viewing height.

As for the higher observation height, although it is still measured by the dimension of "height", it is actually another dimension.

So when the plane appears, the party that owns the plane will overwhelm the opponent in terms of height and observation distance. At this time, the party that owns the plane is actually in a "high-dimensional space" in a broad sense, and there is no plane. On the other hand, it is equivalent to being compressed by the higher-dimensional "two-dimensional plane" of the aircraft into a low-latitude "two-dimensional plane", thus being hit by dimensionality reduction!

The control of electromagnetic power in modern warfare, metal foil jammers, infrared jammers, space troops, hypersonic weapons, stealth fighters, hacker warfare, financial warfare, public opinion warfare, and even biological warfare, which one is not for improving one's own dimension and trying to What about compressing the opponent into a low dimension to attack?

The more attack methods, the more powerful the performance, the higher the dimension, and the ability to compress the opponent, carry out dimension reduction strikes, and improve oneself, which is equivalent to compressing the opponent.

Do you remember the 1991 Gulf War? From a combat point of view, this is a real modern war, an all-round dimensionality reduction strike.

04 How to crack two-way foil?

The two-way foil is a tool used by the singer civilization to eliminate those weak civilizations hidden in the star system with a more complex structure. No matter how advanced and powerful it is, there will be a way to crack it, as long as it reverses itself.

If there is a "short matrix", there will be a "high matrix", and if there is a method for dimensionality reduction, there will be a method for increasing dimensionality such as "kernel function". The offensive and defensive movement of spear and shield will never end, and the game will never stop. All advantages are temporary. If there is a two-way foil, there will be a "three-body box". If you want to lower my dimension, I will increase my own.

In addition to this kind of weapon system competition, there is another supreme way to win without a fight against the two-way foil, which I think is "Wukong".

Clear one's heart, let the mind return to the "empty" state, return to the origin of the universe, and use this "empty" above all things and within all things to dissolve all closed, arrogant, arrogant, Prejudice, acknowledging the existence and value of other civilizations, accepting each other with a broad mind, absorbing each other's strengths with a dialectical perspective, actively integrating with each other and co-evolving together may be the ultimate way out for all civilizations in the universe.

Perhaps at this level, the law of the dark forest will no longer work, and we can safely say: Farewell, Two-Way Foil!

Otherwise, what does a civilization with a closed mind, arrogance, arrogance, prejudice, and powerful weapon technology mean to other civilizations?

Regarding "emptiness", if you are interested, you can read the first part of "The Three-Body Problem", where Shen Yufei's husband, Wei Cheng, tells about his own experience. If you savor it carefully, it may inspire us all.

 就因为看不惯笑果脱口秀的艺人、绰号HOUSE的李昊石拿冒犯我们人民子弟兵的恶俗段子来开玩笑，所以在微博上吐了几句心里话的那位网友，现在已经被反动势力、境外势力和敌对势力这三股势力给盯上了。他在舆论场上发出的那声激起了千层浪的仗义呐喊，最后还是不幸暴露他在黑暗森林中的坐标位置。

一、没有硝烟的战场，斗争一样残酷

如今，我们这位网友已经在包括推特和电报在内的国外舆论平台上被一些蟑螂蛆虫给“开盒”了。所谓“开盒”，就是指我们的个人信息，包括但不限于真实姓名、身份证号码、家庭住址、亲属关系、工作单位和交际网络等，被不法分子通过黑色手段获取之后，在网络上公之于众。

一旦我们被不法分子“开盒”，这就意味着我们在广袤的信息世界里就形同裸奔了。接下来，不只是我们的社交账号会被“三股势力”重点关注、定点打击、反复灌水、长期举报，而且我们的手机号码也会被它们列入黑名单之中，紧接着就是各种不堪入目的骚扰短信铺天盖地、没完没了的狂轰滥炸，让你饭也吃不下、活也干不好，觉也睡不着，让你的精神压力无时无刻都处于高度紧绷的状态，直到把你脑子里头的那根弦给崩断，把你给逼疯，甚至是逼死为止。

因为我们的家庭住址已经被暴露了，所以我们再往后可能还会收到“三股势力”给我们送上门来的各种“亲切问候”和“意外惊喜”。什么东西看起来是恶心的、肮脏的、吓人的，它们就会挑着这些东西给你寄快递。拆包裹本来应该是一件很让人期待的事情，但当你的坐标位置在黑暗森林中暴露之后，你永远不知道你拆开的下一个包裹里装着的是鲜花还是狗屎，是礼服还是寿衣，是蛋糕还是蟑螂。当你明白下一秒可能会有不知从哪儿射出来的冷枪暗箭扎你一下的时候，你没准就不再敢下快递，不再敢点外卖，甚至是不再敢出门了。

因为我们的工作单位和人脉背景也被暴露了，所以不光只是我们，就连我们的父母、我们的爱人、我们的孩子、我们的朋友、我们的同事，甚至是那些和我们素昧平生，只是在赛博世界里萍水相逢的网友，都有可能会被“三股势力”制造出来的殖子给盯上。然后，殖子就会把我上面提到的那些个原本只是针对我们个人的腌臜手段，在他们的身上如法炮制。

我为什么会对这些东西了解得那么清楚，可以做到如数家珍？因为我也和那位微博网友一样，早就被“三股势力”在境内外的各个社交媒体上给不法分子开了盒了。而且我的盒被开得更彻底，如果说其他被“三股势力”盯上了的人在网络上充其量算是裸奔的话，那我这个简直可以说是被它们用X光照过、用胃镜看过、用柳叶刀切过了。而且这个只是过程，并不是结果，它只有进行时，没有完成时。

二、好人被人用枪指着，我们不能袖手旁观

多年来一直关注和支持我的一些同志、朋友和铁粉应该都知道，我以前出内容的频率其实并不像现在这么高，一天好几个文章加视频，还动不动就是长篇大论。因为在以前，除了自媒体之外，我是有自己的本职工作的，这份工作我已经干了挺长时间了，不过最后我还是选择了辞职。

这不是因为我对这份工作有什么不满，也不是我觉得把时间和精力省下来都用来做自媒体可以挣得更多，而是因为，我已经是个被开过盒的人了，我在黑暗森林中的坐标位置已经暴露了。“三股势力”对我的痛恨是刻骨的，殖子对我的纠缠是长期的。我就是颗铜豌豆，它们怎么蒸我煮我、锤我炒我，都无所谓，可是我没法看着和我共事的人因为我的城门失火了而遭到殃及，所以我最后还是选择不给同事们添这份麻烦，专专心心回家当大妈吧。

很难说这个结果是不是那些直到现在还在我的虹膜上制造倒计时幻影的殖子，以及躲在幕后或操纵或怂恿着殖子的“三股势力”所期望的。你要说是吧，我的原先的本职工作已经在它们的反复折腾下搞丢了，我失去了一个独立的经济来源，变成了基本只能靠打赏和带货来补贴点家用的家庭妇女；可你要说不是吧，我现在腾出来的精力更多了，我可以出更多更长的文章和视频了，我能够倾泻在殖子和“三股势力”身上的弹药比以前多多了。

而且，我也是在被逼到了这个阶段之后，才终于想明白了这样一个道理：在人生的不同阶段，我们看到的风景是不一样的。无论我们一开始是怀着怎样的心情踏上的旅途，是喜欢是热爱，是反感是愤慨，当我们走了足够远之后，遇上疾风骤雨、电闪雷鸣，这都是很正常的。毕竟那么长的一条路，怎么可能都是阳光明媚、风和日丽呢？

如果只是七八级的大风和几十毫米的降雨，很多人或许还能忍得住，可要碰上的是十几级的台风和上百毫米的暴雨呢？这时候一些人估计就要打退堂鼓了，对此我感同身受，我觉得在看这期内容的各位也能将心比心。

事非经过不知难。我也是被网暴过的人，我清楚在经历了这种突如其来的生活变故之后，一个人会陷入怎样的内心煎熬和自我怀疑当中。所以在这种时候急流勇退并不是逃避，而是为了保护自我所采取的战略撤退。存人比存地重要得多，这样的取舍是完全合情合理的。不管是哪一位在黑暗森林中暴露了坐标位置的朋友，无论你们因为任何理由暂时或长期地远离网络空间，我都将理解、尊重并支持你们的选择。

但是，光理解是不够的。此时此刻，我的心情，和《潜伏》中发现天津地下交通站的联络员秋掌柜被军统抓捕后的余则成是一样的。秋掌柜被绑在军统审讯室的老虎凳上，被国民党特务们的严刑逼供折磨得已经不成人样了，这样的场景再望一眼，余则成的眼泪都忍不住要掉下来了。

听着秋掌柜抱着必死决心说出来的那句“别做梦了，谁也不能战胜我的信仰。我可以去死，但我绝不会出卖我的战士”的忘我告慰；看着他宁肯拼尽最后一丝力气也要咬断舌头，只为了不牵连到战线上的其他同志的无畏风采，我觉得我的胸膛也和余则成的一样，也有一股血液乱撞，要破腔而出。余则成当初没有对身陷虎口的同志袖手旁观，我也不能允许自己就这么高高挂起，我也必须为我们的秋掌柜做点什么。

三、别怕，这一次二向箔掌握在文明的手中

因此，我决定郑重地向舆论场上那片广袤的黑暗森林再进行一次明码广播。所有还在想方设法、各种使坏的殖子，以及它们背后的组织，以及它们组织背后的势力，你们听好了。

我知道，在你们的眼中，现在的我们依然只不过是微不足道的虫子而已。你们还是会躲在监视器后头，暗戳戳地嘲笑我们，轻蔑地认为你们羞辱乃至是消灭我们的行为和我们没有任何关系。但在经历过你们这些年制造出来的各种障眼法，比如视网膜上的幻影，比如赛博宇宙的闪烁之后，我现在也悟出舆论场上的黑暗森林法则了，那就是比起我们这群虫子来，你们这些自诩掌握了所有主动权、自认为优势在我的家伙，其实更害怕暴露你们自己的坐标位置。

你们从不敢站出来以自己的真面目示人，和我们摆事实、讲道理、评公道、论逻辑，你们只会像栖息在下水道里的老鼠一样，只有在夜幕降临时才敢窜出来吓人。你们要不是因为有三体人提供的软硬件支持，有它们施舍的源源不断的美元、日元和新台币维持生计，有它们提供的远程协助和技术指导，面对着我们，把你们之中的任何一个个体单独摘出来，我想，它大概会更害怕我们这群虫子。

你们的组织度、资金链和科技树水平显然是在我们之上的，我对此并不怀疑。可话又说回来了，你们那点优越感说到底不也只能用来欺负欺负我们这些小虫子吗？在掌握着更高科技、更大组织和更强力量的更高等的文明面前，你们那引以为傲的殖子也好，水滴也罢，不也一样算不了什么吗？

很显然，你们的手里并不掌握二向箔和光粒这种真正意义上的降维打击武器，我的坐标位置你们早就掌握了，要是拥有这种足以颠覆认知的造物，你们还能让我在赛博宇宙里喘息那么长时间吗？

我不仅在赛博宇宙里见识过二向箔的威力，只不过那个被它拍扁了的对象并不是我们这些虫子，而是那些拿我们这群虫子当中的军人来开恶俗玩笑的、自认为和你们是一路人的、总觉得自己手里也拿着苍蝇拍和杀虫剂的所谓高等生物罢了。

相比我们这群虫子，这些跟一帮人说几个搞笑段子就有几十乃至是上百万收入的家伙，或许觉得自己有资格自称为高等生物，可那又如何呢？二向箔一展开就可以覆盖960多万平方公里，一下子就能将8位数的财富给清零，而且还将那群往日里一直高高在上的家伙一下子就给拍成了二维生物。

可怕吗？对你们而言或许是的，但我这群虫子只觉得庆幸，庆幸像二向箔这么强大的武器，这一次还好是掌握在文明的手中。

我很清楚，你们之所以会集火攻击那个揭露了这群高等生物的卑劣行径的网友，并不是因为你们有多同情它们，也不是因为它们和你们存在什么利益往来。因为抹黑我们、离间我们、分化我们，乃至是挑唆我们互相攻击，引诱我们自焚房梁，解构我们的宏大叙事，本来就是你们这帮玩意拿了钱就得干的分内工作。

我们或许是虫子，但是你们说穿了也不过就是黑暗森林中的火鸡而已，你们甚至比我们更害怕暴露你们自己的坐标位置。因为我们的暴露充其量也就是会招致网暴，接到几条骚扰的短信，收到几件绣花的寿衣，你们呢？你们要是暴露了，不仅要面对成千上万的罚款，可能还得背负沉重的牢狱之灾，甚至这辈子都得在铁窗下细数自己前半生犯下的深重罪孽。

当然，你们之中也有一些个东西仗着自己不在中国大陆，觉得自己就可以高枕无忧了，就可以心安理得地接着吃你们的卤肉饭、天妇罗和汉堡薯条了。对于这种玩意，我只能说：祝愿你们能够融入你们自己选择的新圈子里，不要在外头受了委屈就腆着脸去找我们的驻外机构求助，也不要跑到社交平台上用简体中文诉苦，更不要因为在外头混不下去了又夹着尾巴溜过来。

因为这种事情我见得太多了。好多殖子觉得，润到了三体星就是人上人了，却完全没有想过，自己在三体人的眼里，自始至终都是工具人而已。你们就算和当地人产生了生殖隔离我都不奇怪，我就不信三体星上有那么多傻子真能和一群火鸡共情的。

当工具人就要有当工具人的觉悟，无论是在境内还是境外。1450万新台币不是那么好拿的，这些是真正意义上用来买良心的钱。等到什么时候心肝脾肺都被三体人挖完了，身为火鸡的你们距离被宰的那一天也就不远了。

结语、坚持真理，哪怕谎言恼羞成怒

今天这个话题，是由那位勇敢揭露了笑果冒犯子弟兵的恶俗段子的网友，因为个人信息被“三股势力”挖出，进而惨遭集中针对和迫害这件事情所引起。我结合我过去的一些个人经历，抒发了一点个人感想，也壮着胆子向潜伏在黑暗森林中的那些魑魅魍魉再一次进行了广播。

按说话说到这里其实也就差不多了，但我总觉得还有心事未了，所以在今天这期内容的最后，我想和所有粉丝、所有关心和支持我的朋友、所有有志于帮我们大家伙解决挨骂问题的同志，说两句心里话。

陈毅元帅说过，淮海战役的胜利是人民群众用小推车推出来的，舆论战场上的斗争其实也一样。这个战场上或许没有硝烟，但在这里进行的所有厮杀都是同样残酷的。解决挨骂问题从来都不只是政府官方和主流媒体的事情，就好像当年的抗日战争和解放战争，那也不只是八路军、新四军和解放军的事情。只有我们人民群众充分动员起来、参与进来，积极投身到这场艰巨而光荣的事业中，我们才有希望获得最后的胜利。

什么叫做人民当家作主？为了我们自己，为了我们的朋友，为了我们的家人，为了千千万万奋斗在不同岗位上支撑这个社会正常运转的劳苦大众，为了守护万家灯火手握钢枪夙夜坚守在边疆的人民子弟兵，为了我们这个上溯至一千八百四十年，无数革命先烈和仁人志士抛头颅、洒热血才获得了浴火重生的古老国度，大家今天能够站出来勇敢发声，捍卫真理，坚守道德底线，同丑恶和谎言作顽强斗争，这就是人民当家作主。

什么叫做民主？民主的定义难道只能被归纳为西方狭隘语境下的选票游戏吗？不，民主不该是那样的。人民当家作主也是民主，人民当家作主就是民主，人民当家作主才是民主。民主不只是一项权力，它更是一种义务，只要是关乎我们大家的事情，关乎这个集体的事情，关乎中国人民的事情，我们就应该站出来，能做事的做事，能发声的发声，有一分热，就发一分光，不用去等待炬火。就算没有炬火，我们也能靠自己的众人拾柴，在黑暗中创造出属于我们的光明。

我也只是一个普普通通的中国大妈，但我一样可以用我的方式，我的努力，我的坚持，去为我们的集体做我力所能及的事情。它们打它们的，我们打我们的，又不是只有它们会解构主义这一套，谁说寿衣就不能是礼服呢？

不要因为视网膜上的幻影和赛博宇宙的闪烁就觉得天都塌了，人间公道不存在了。谎言留给我们的第一印象，往往是假装的真理。对真理的坚持并不总是意味着我们会收获鲜花和掌声，点赞与打赏，欢呼同歌颂，它同时也可能是冷枪和暗箭，谩骂与羞辱，骚扰同威胁。

对真理的坚持，往往也就意味着对谎言的蔑视。我们越不相信它，它就越是容易恼羞成怒，它一发怒就会原形毕露，一撕下画皮就会对我们张开血盆大口。

那又如何？任凭它们用谎言编织起来的诅咒，再大一些又何妨？只要对真理的信念足够坚定，我们的耳朵所听到的，就是唱给勇者的赞歌。

有评论者说“为何不研究如何制造二向箔”。

今天我们暂时放下《三体》电视剧不表，胡言乱语一番自己对二向箔的理解，浅度解析一下二向箔的数学原型、打击原理。

并从战争的角度，看看地球人类是不是也已经拥有了类似二向箔的打击手段，并探讨破解二向箔的措施。

01 二向箔是什么超级武器？

二向箔是《三体III：死神永生》中登场的降维打击武器。

在第三部中，一艘来自歌者“母世界”的宇宙飞船，发射了一片二向箔，瞬间将太阳系二维化，太阳系所有的生命都变成了一幅画。

根据《三体》原著介绍，二向箔大概是这样子的：它是一片特殊处理过的二维空间，长8.5厘米，宽5.2厘米，没有厚度。（先提醒一下，有厚度并不意味着一定是二维的！）

二向箔在封装状态下由特制力场束缚，可永久保存，呈现出晶莹剔透的透明纸片状，而待机状态下其封装力场逐渐消散时会发出柔和的白光，看起来就像是一张完全无害的二维薄膜，并以光速飞向目的地。

二向箔到达三维空间后，凡是接触到二向箔的三维物质，都会被二维化，也就是所有的东西都变成没有厚度的薄片，并呈现出三维的某些细节。

看完二向箔的介绍，学过《线性代数》与《高维统计学》（或多元统计学）的观众们，是不是觉得很熟悉，二向箔的原理和《线性代数》中的“扁矩阵”是不是很类似？

和《高维统计学》中的主成分分析（POA）、主坐标分析（PcOA）、多维标度法（MDS）是不是很类似？

和单细胞转录组学（包括空间转录组学）中的tSNE非线性降维算法，以及UMAP降维算法是不是很类似？

02 今天我们结合二向箔，简单介绍一下“扁矩阵”

“扁矩阵”是矩阵的一种，可以对空间进行压缩或降维操作。

学过《线性代数》的观众大概都还记得，矩阵是一种变换（或者说一种映射），把变换对象映射到一个新的空间（或坐标系），而矩阵乘法则是一种特定的线性变换。

对于一个M*N的矩阵来说，如果M=N，这个矩阵就是一个方阵，对于方阵来说，2x2的可逆方阵表示就是二维空间的可逆变换; 3x3 的可逆方阵表示三维空间的变换。

但是对于非方阵而言，如果一个M*N的矩阵，如果M<N，那它就是一个“扁矩阵，如果矩阵的行数M为2，列数N为3的话，它所进行的变换类似二向箔的降维打击，在它的作用下，被变换对象被执行了扁平化操作，从三维被压缩到二维，同时在被压缩的过程中，信息发生了部分丢失。

诸位说一说，是不是有点像？

还有一个事情，大家都知道地球是个类似球体的行星，是三维的，而我们常用的世界地图，则是二维的，把三维的地球仪做成二维的地图，是不是也类似二向箔的降维打击原理？

三维地球变成二维地图，在空间距离的表示上，多采用多维标度法，也就是通常说的“用欧氏距离来近似测地距离”，或者说，就是一种在低维空间展示高维空间“距离”数据结构的多元数据分析技术。

这样看来，二向箔技术原理，不仅仅可以用来毁灭宇宙中的“低等”文明，也可以为文明的生存发展服务。

对于主成分分析、主坐标分析以及tSNP、UMAP，它们与二向箔的相似之处，各位观众可以回顾一下学过的知识或找些资料自己研究、比对，在此就不啰嗦了。

03 地球上有没有二向箔武器？

目前没有！

但二向箔的降维打击原理，在地球上可以说，早就存在并大规模运用了。

《三体》中说，二向箔是没有厚度的，只有长度和宽度，其实我们可以换个角度理解空间和维度。

“空间”不是某种容器（比如曾经的以太理论），“空间”是事物本身存在的自在状态。

而“维”则是事物的某种特征或能力，“维度”就是对事物的某种特征或能力的度量。

在理解“度量”时，把“无”和“没有”理解为“相对小”，而不是什么都没有，不然在解释地球上的“类二向箔”武器系统时，会陷入抠字眼的争论中，掉进绝对化的黑洞出不来。

大家都知道，历史上的海战，都是在海平面上进行的，双方都只能在目视距离用火炮作战，所以战舰的桅杆都会造得很高，以便做到先敌发现，先敌开火。

对这个平面，不能理解为没有高度的，因为相对低，对于更高的观察高度而言，则是一个“平面”。

而更高的观察高度，虽然还是用“高度”这个维度来度量，但其实是另一个维度了。

所以当飞机出现后，拥有飞机的一方，在高度上压倒对手，就在观察距离上压倒了对手，这时候，相对拥有飞机的一方，其实就处于广义上的“高维空间”，而没有飞机的一方，则相当于被飞机这个更高维度“二维平面”压缩到了一个低纬度的“二维平面”，从而被降维打击！

现代战争的制电磁权、金属箔干扰器、红外干扰器、天军、超高音速武器，隐形战机、黑客战、金融战、舆论战、乃至生物战，哪个不是为了提高自己的维度，并试图把对方压缩到低维度进行打击呢？

打击手段越多，性能越强悍，就拥有更高的维度，就能压缩对手，进行降维打击，自己提高了，也相当于把对手压缩了。

大家还记得1991年的海湾战争吗？从作战角度看，这就是一场真正的现代化战争，一场全方位的降维打击。

04 如何破解二向箔？

二向箔作为歌者文明用于清除那些隐藏在结构较复杂的恒星系统中的弱小文明的工具，它再先进、再厉害也会有破解之法，只要对自己进行反向操作即可。

有“矮矩阵”就会有“高矩阵”，有降维的方法，就会有“核函数”等升维的方法，矛与盾的攻防运动是永远没有尽头的，博弈永远不会停止，一切优势都是暂时的，有二向箔就会有“三体箱”，你要降我的维，我就升自己的维。

除了这种武器系统的竞赛外，对二向箔还有一种不战而胜的无上法门，笔者认为就是“悟空”。

把自己的心清零，让心灵回归到“空”的状态，回归宇宙的本源，以这种在万物之上，又在万物之中的“空”，化解掉一切封闭、傲慢、自大、偏见，承认其他文明的存在与价值，以博大的胸怀兼容并蓄，相互接纳，以辩证的眼光彼此吸收对方的优点，主动相互融合、共同进化，或许才是宇宙各文明的终极出路吧。

或许到了这种境界，黑暗森林法则就不起作用了，我们可以放心地说：永别了，二向箔！

不然，一个心态封闭、傲慢、自大、充满偏见并拥有强大武器科技的文明，对其他文明意味着什么？

关于“空”，感兴趣的可以阅读《三体》第一部，申玉菲的先生魏成讲述自己经历的那一段，仔细品味，或许对我们大家都有所启发。
