Harry Potter’s Morning Light

   Chapter 2186 Flower dispute (ninety-four)

   In Dublin, 1709, "On the New Vision" has this sentence:

Although mathematicians try to use lines and angles to explain the perception of distance, those lines and angles themselves are invisible, and people who are not good at optics have never thought of them. Most people do not carry a rangefinder at all times. , or whether he wants to calculate the distance based on the size of the angle between the two optical axes after he has seen an image of an object.

Everyone judges what is his perception and what is not. If we don't realize that some lines and angles give rise to various ideas of distance in our minds, even if mathematicians in the world tell me that I perceive them, it is not in vain. What?

  Any idea cannot be perceived in itself, and we cannot perceive other ideas by it.

The man who wrote the book was George Berkeley, an opponent of Isaac Newton. When Newton and Leibniz created calculus, which became an important tool for solving many problems, Berkeley used "infinitesimals". The logically rigorous question of whether it is 0" attacked Newton.

   For example, two mirrors are placed opposite each other, and a puppet is placed between the two mirrors, so that countless puppets will be formed. This experiment can be easily done at home. At this time, are there finite or infinite images in the mirrors?

  Considering that light is energy, after the light is reflected many times, the intensity will drop to the point where it cannot be imaged.

Assuming that there is no loss of light in the multiple reflections of the two mirrors, then as the number of reflections increases, the puppet will become smaller and smaller, and finally it is so small that it cannot be observed by the human eye. Does this image that cannot be observed by the human eye does not exist? of?

Placing two mirrors opposite each other will create a perspective effect, which looks like a corridor, but in fact the two mirrors are still flat, unless there is another three-dimensional world in the mirror, which is usually a plot in novels and stories. . But the image of the mirror does produce a "sense of distance", which is also put forward by the Arab scholar, "as the distance between the reflections increases, people will be invisible because of this smallness".

  Infinitesimals are said to be zero in Newton's theory at one time and not zero at other times. Berkeley ridiculed infinitesimals as "the ghost of dead quantities", which is also the key point of the flaws in Newton's theory.

"0" in Arabic numerals stands for nothingness and nothing, but a long time ago, human beings did not have the concept of "0", or the logic was not valid. For example, there are still things such as oxygen and nitrogen dioxide in "vacuum". Gas, the Dirac Sea representing the quantum vacuum is full of negative energy electrons, and although these particles are unobservable, they are not illusory, matter seems to float on the surface of the Dirac Sea.

  When matter and antimatter meet, the annihilation effect cancels each other out, an explosion occurs and a huge amount of energy is generated.

   Of course, explain this to a beggar, he has absolutely no idea what the other party is talking about, he only knows that there is a "0" in his pocket, not a single copper. There was a story, a philosopher asked the boatman if you knew history, grammar, etc. When he fell into the water, the boatman asked the philosopher if you could swim, the philosopher said "no", so Said the boatman, "What a pity you will lose your whole life."

   "Zhuangzi·Xu Wugui" says that a Chu countryman annoyed the boatman when he was crossing the river in the middle of the night. Maybe this is how he angered the boatman.

  Georgianna really wanted to finish the book, not attend any conference, especially when she saw Platinum Malfoy.

But she didn't want to anger Carolan like the "philosophers" and the "Chu people". This Calais meeting has been prepared for a long time. Because of the Muggle war and revolution, the British Ministry of Magic has cut off communication with Europe. Now they want to re-cooperate on trade and set international trade standards, which are opposed by the French Ministry of Magic.

   The French side has been asking if Naga has been found, and Malfoy pretended to ask if it was considered a contraband in trade.

The real purgers from the United States were smoking outside the door and listening to the quarrel of the wizards, seemingly at ease. Most of the "purgers" who were targeted were Muggles, and only a few would use the summon Garuda. Ability.

When the noise was exhausting, the "meeting" finally came to an end, and then Georgiana was "invited" to visit the coastline of Calais, and there would be a huge tree that looked like a stout, totem pole, about a mile away. , they are hidden in the forests of the coast of Calais. After the divination bird used in the experiment flew to a certain height, its leaves fell on their own, looking like some kind of very light net, as the sea breeze blew towards it, and then entangled it tightly.

   The person who built it showed a smug smile, and Georgiana looked at the augury. Even though its cry was unbearable, it was still too pitiful at the moment.

   It can be seen that it is impossible to go back and forth on the coast of Calais at will with a broom.

   She felt sorry for Newt Scamander for two seconds, and then announced the deployment of anti-apparition, and the others looked at her inexplicably, as if they didn't know there was a magic called Apparition.

   Immediately after she saw the American purger, he showed a meaningful smile.

  The war between the mandrill and the Yin clan has existed for many years, and the war between the purger and the wizard has not ended. Even if the "real world" has disappeared, it still exists in the "dream world".

  This world cannot use Apparition, this is a "rule", just like in another world where Apparition can be used, wizards and Muggles need to overcome the problem of "distance".

The purgers knew no less, or more, than Georgiana, they knew how to use that special metal to make a forbidden magic ring to make wizards lose their magic, so that they were no different from Muggles, only Ani Margos' transformation can break through its shackles, otherwise he will be like the duke who was sent to the guillotine, break through when he is on the verge of death, and use an invisibility spell on his neck to make the executioners and spectators think that he died.

   is like a magic show, except that after the magician cuts the actress into two pieces, people wonder that she is still alive.

  Napoleon once said that if there is only one capital in the world, it must be Istanbul.

She hoped he would listen to what Rousseau had to say. It was in everyone’s interest to weaken an arrogant enemy who wanted to rule the world. Grindelwald wanted to let wizards rule the world. And the desire to use magic freely - I have power, why can't I use it to my advantage?

   If a Muggle has a target he wants to kill, give the wizard enough money, and he can use the Avada Suo to make the opponent die as if they were asleep. There is no trace of this method of killing, and an autopsy will not find trauma and poison anyway.

  Wizards can live a lot better than they do now, when did pure blood see Muggles as human beings?

   Both the police state and the spy rule are very bad, but Georgiana feels that the wizards in the West cannot be the same as the East, and must have international secrecy laws, otherwise the behavior of wizards will not be restrained at all.

  The East is the other way around. Often times, "mortals" pretend to be sorcerers and ask believers to pay, or worse.

  Ignorance and unconsciousness will make you much happier, and it is easy to be deceived.

  Humans have no wings, but have legs. A journey of a thousand miles begins with a single step, read thousands of books and travel thousands of miles. Every year, I will go to Mecca for a pilgrimage. When Xuanzang went to the West to learn scriptures, Mo Sheng was also uniting the Arabian Peninsula, and then there was the Caliphate and the Abbasid Empire. etc.

  How can people who live in such a beautiful cage as a garden know the vastness of the world and the joy of traveling freely?

   But this is what Cao Xueqin wants, a life and love without turmoil, he is someone who has endured hardships, and she also understands his feelings. She just didn't want to use all her scheming to get more money, compete for the so-called position in a gorgeous cage, and a man's love.

   She shook her head and turned to the page she looked at before leaving to see what would happen next.
