Harry Potter Morning Light

In "On the New Vision", published in Dublin in 1709, there is this sentence:

Although mathematicians try to explain the perception of distance with lines and angles, those lines and angles themselves are invisible, and people who are not proficient in optics have never thought of them, and most people will not carry a range finder at all times , or after seeing an object, whether he should calculate the distance by the angle between the two optical axes.

Everyone will judge what is his own perception and what is not. If we are not aware that some lines and angles cause various concepts of distance in our minds, then even if the mathematicians in the world tell me that I perceive them, it is not in vain. what?

Any idea which cannot be perceived by itself cannot be used to perceive other ideas.

The person who wrote this book was George Berkeley, who was an opponent of Isaac Newton. When Newton and Leibniz created calculus, which became an important tool to solve many problems, Berkeley used "infinitesimal quantities The logically rigorous question of whether or not it is 0" attacked Newton.

For example, place two mirrors facing each other, and place a doll between the two mirrors, so that countless dolls will be formed. This experiment can be easily done at home. At this time, are there finite or infinite images in the mirror?

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

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

Two mirrors placed 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, this kind of plot is usually only in novels and stories . But the image of the mirror does produce a "sense of distance", which was also proposed by the Arab scholar, "As the distance between the reflections increases, people will not see because of this smallness."

In Newton's theory, infinitesimal quantities are said to be zero for a while, and for a while they are not zero. Berkeley ridiculed infinitesimal quantities as "the ghost of dead quantities", and this is also the key point of the flaw in Newton's theory.

"0" in Arabic numerals represents nothingness, nothing, but a long time ago, human beings did not have the concept of "0", or the logic was not established. For example, oxygen, nitrogen dioxide, etc. still exist in the "vacuum" The gas, the Dirac sea representing the quantum vacuum, is filled with negative energy electrons, and although these particles are unobservable, they are not illusory, and matter appears to be floating on the surface of the Dirac sea.

When matter and antimatter meet, the annihilation effect will cancel each other out, an explosion will occur and huge energy will be generated.

Of course, if you explain this to a beggar, he has no idea what the other person is talking about. He only knows that there is "0" in his pocket, not a single coin. There was once a story, a philosopher asked the boatman, can you know history, grammar, etc., when he fell into the water, the boatman asked the philosopher, can you swim, the philosopher said "no", so The boatman said, "It's a pity that you will lose your whole life."

"Zhuangzi·Xu Wugui" said that a man from Chu State angered the boatman when he was crossing the river in the middle of the night. Maybe this is how he angered the boatman.

Georgiana wanted to finish that book more than attend a meeting, especially if she saw Platinum Malfoy at the meeting.

But she didn't want to anger Caroline like the "philosopher" and "Chu people". This Calais conference has been prepared for a long time. Because of the Muggle wars and revolutions, the British Ministry of Magic has cut off ties with Europe. Now they want to re-cooperate on trade and formulate international trade standards, but they are opposed by the French Ministry of Magic.

France has been asking if Naga has been found, and Malfoy pretends to ask if it is considered a contraband in trade. The cooperation between the two countries to capture the "Scavenger" and the Garuda almost fell through.

The real scavengers from the United States were smoking outside the door while listening to the wizards arguing endlessly, seeming to be at ease, but most of the "scavengers" who were targeted were Muggles, and only a very few of them could use Summon Garuda Ability.

The "meeting" finally came to an end after the quarrel was exhausted, and Georgiana was "invited" to visit the coastline of Calais, and there would be a giant tree that looked very thick and looked like a totem pole about a mile away. , they hide in the forests on the coast of Calais. After the Bu bird used in the experiment flew to a certain height, its leaves fell off by itself. It looked like some kind of very light net, blowing towards it with the sea breeze, and then tightly entangled it.

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

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

She felt sorry for Newt Scamander for a couple of seconds before announcing the anti-apparition spell, and the others looked at her puzzled, as if they didn't know about the magic of apparition.

Then she saw the American purger, and he smiled meaningfully.

The war between the mandrill and the Yin tribe has existed for many years, and the war between the scavengers and the wizards has not ended. Even if it is gone in the "real world", it still exists in the "dream world".

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

The scavengers know no less than Georgiana, or even more. They know how to use that special metal to make the magic ring, so that wizards lose their magic power. In this way, they are no different from Muggles, only Arnie Magus can break through its shackles by transforming, otherwise, like the duke who was sent to the guillotine, break through when he was on the verge of death, and cast an invisible spell on his neck, making the executioners and spectators think he died.

It's like a magic show, except after the magician cuts the actress in half, people wonder if she's still alive.

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

She hoped he would listen to what Rousseau had to say, it would be in everyone's interest to weaken an arrogant enemy who wanted to rule the world, Grindelwald wanted wizards to rule the world, and he cleverly took advantage of wizards' distaste for the International Statute of Secrecy, And the desire to use magic freely - I have the power, why not use it for my own gain?

If a Muggle has a target to kill, give the wizard enough money, and he can use the Avada Kedavra Curse to make the other party die as if asleep. There is no trace of this method of killing. Anyway, no trauma or poison will be found during the autopsy.

Wizards can live a much better life than they are now. When did pure blood treat Muggles as human beings?

Both the police state and the rule of secret agents are very bad, but Georgiana feels that it is impossible for wizards in the West to be the same as in the East. They must have the International Law of Secrecy, otherwise they cannot restrain the behavior of wizards at all.

In the East, it's the other way around. Many times it's "ordinary people" who pretend to be wizards and ask believers to pay money, or worse.

Ignorance and ignorance will be much happier, and it is easy to be deceived.

Humans don't have wings, but they have legs. A journey of a thousand miles begins with a single step, reading thousands of books and traveling thousands of miles. Every year, the emperor would go on a pilgrimage to Mecca. When Xuanzang went to the West to learn scriptures, the holy man was also unifying the Arabian peninsula, and then there were the caliphate and the Abbasid empire. etc.

How can a person living in such an exquisite cage as a garden know the vastness of the world and the joy of traveling freely?

But this is what Cao Xueqin wanted, a life and love without turmoil. He is a person who has endured hardships, and she also understands his feelings. She just didn't want to go all out in order to get more dividends from Luo Tan, competing for the so-called position in a gorgeous cage, and a man's love.

Shaking her head, she turned to the page she had read before leaving to see what would happen next.
