Harry Potter’s Morning Light

  Chapter 2940 Can't ride the wind (7)

  The auditorium of Hogwarts has many functions, but it is most often used as a "dining hall", and there are very few opportunities to hold "ceremonies" in a year.

It always smelled of food rather than spice, and maybe once, when Dumbledore was a Transfiguration teacher, there was a Fountain of Luck in the school because Kettleburn disguised the Ash Snake as an earthworm , and then the entire auditorium was set on fire.

   For a long time, the "auditorium" was filled with a burnt smell, and the long wooden table used in the courtyard was also burned instead of the original one. The new wooden table looks beautiful with a layer of fire-resistant wax. The original long table is worn out after so many years of use, but people still miss the old table.

   Someone even found doodles on the desk from great-great-great-grandparents who were once as young as their grandchildren.

   But that's not what's going on here.

  At that time, there was an episode in the accident. The "unlucky knight" fell in love with "Amata" and "Asha" respectively. At first they could barely restrain themselves, but after the ash snake exploded, they took advantage of the chaos to duel.

This time it was Gryffindor's "Unlucky Knight" who caused a conflict between the two girls because of the problem of the celestial dance partner. First of all, he and Gryffindor's "Amata" were friends, and he really liked It is Hufflepuff's "Asha", who served as "Asha's" bodyguard during the portrait curse that appeared in the school, and felt what he could not feel from "Amata".

  He and "Amata" have known each other since they were young. Although childhood sweethearts are very romantic, there is a chance that they will become brother and sister, not to mention that he doesn't think that the jokes made by his parents when they were young should be taken seriously.

  "Asha" also knew about this relationship, and she didn't think it was a problem when she saw "Unlucky Knight" and "Amata" as a pair. A few years passed without incident, and it was not until the Celestial Ball invited a dance partner that "Amata" noticed the existence of "Asha", and then they started fighting.

  After the incident, the "unlucky knight" immediately severed contact with "Asha", but he was not with "Amata" either, he would rather play with "brothers".

   This matter was left alone, although occasionally "Asha" and "Amata" met in the auditorium or other places, but they just met each other, and the air was filled with fire and lightning.

The outbreak of "Amata" has nothing to do with Emily Taylor directly. It is the members of her inner circle who fan the flames in the ears of "Amata", and then "Amata" and "Asha" are in the auditorium He yelled and cursed, and Pomona happened to see the scene when he entered the auditorium.

  The layout of the college's long table is roughly like this, with Gryffindor and Slytherin's tables on the outermost side, separated by Ravenclaw and Hufflepuff. But this is not absolute. Occasionally the principal will arrange other tables, and the prefects will receive the news in advance, and then sit at the assigned long table, and other students will sit there when they see the prefects.

That is to say, when "Amata" and "Asha" quarreled, there was a long Ravenclaw table between them. When "Amata" and "Asha" took out their wands and shot at each other, a Ravenclaw Crowe's boy got the Hairy Curse, and now he's in the hospital wing.

When Bill said that he saw what kind of person Emily was, Pomona wanted to say a few words for her, but when she saw the chaos around her and Emily and the gang members smiling so happily, she The only bit of empathy is gone.

  She has always disliked the authoritative classroom, where the students sit, the teacher stands, and in her greenhouse everyone stands. I also don't like to use "this is the rule" to block all doubts.

  The clown said on the Murray talk show that no one is polite at all (civil).

  civil and manner both mean polite, but they are different.

  Emily has good table manners and looks elegant, but her "civil" is terrible.

   Just as Pomona was looking at the crying "Asha" and her mind was in chaos, there was a knock on her office door.

   "Come in," she said, and the door opened.

  In the garden outside the Tuileries Palace, there is a large fountain. During holidays, many parents take their children there and put the small sailboats they made in it.

  Brussels Museum does not have such a spacious space for children to put boats, but made a large glass tank, through which you can see what the boat looks like in the water, and Fresnel is explaining it to the children.

  Dolphins are very smart animals. They know how to follow human ships and reduce resistance. At present, most ships use a forward-sloping bow. Although the bow curve has a certain angle with the water surface, the water pressure on the impact surface will increase after the oncoming water flow hits the bow. After the area is removed, the water surface will fall again, thus forming wave-making resistance.

  Although it looks more imposing, it affects the sailing of the ship, and as the waves increase, not only will the wave resistance be greater, but the passenger experience will also become worse.

   When Napoleon led his troops from France to expedition to Egypt, it just happened to encounter a storm. The rough seas not only prevented the ship from moving forward, but also made many people seasick.

  When the British returned to France with a large number of Egyptian cultural relics and French soldiers, the weather happened to be calm, and there were not as many seasickness as last time.

  Vitruvius has discovered "disturbance waves", such as throwing two stones into water, the two will superimpose and weaken. If the first sound is not blocked, the second sound will not be blocked, and the highest and lowest points will reach the ear without echo at all.

  The ancient Greek opera houses did not have roofs, which tested the lung capacity of the singers, because the sound would spread out, which certainly avoided the echo interference, and also made the direct sound that the audience could hear smaller. Buildings in opera houses with roofs must consider echoes and reverberations, and echoes are not welcome at this time.

The best way to eliminate wave-making resistance is to add a wave. When the peak and trough meet, the peak of wave-making resistance will be reduced, thereby increasing the speed of the ship and the riding experience of passengers. But how to design this offset What about waves?

If the sailor knows the speed and direction of the ocean current well on a route, he can add a bulge to the bottom of the ship, and the sudden expansion will form a wave when moving forward. When the wave speed and wavelength are within the same range, the wave-making resistance can be reduced. But this means that the speed cannot be too fast, nor too slow, otherwise the protrusion will fail.

This kind of ship will be on the route that operates all year round, and it is only used before the age of sails. At that time, ships in the Mediterranean Sea were still rowed by manpower. Worrying, when the war is fierce, soldiers will be needed to paddle, and the role of the battleship is mainly to load soldiers rather than slaves and goods.

   Around 50 BC, the main battleships of ancient Rome followed the idea of ​​ancient Greek warships, but they changed the protrusion on the bow to a wolf's head, which is more decorative.

  Miss Lamont's words will definitely make some people feel angry, but the ancient Greek teachers were slaves in the eyes of the ancient Roman nobles, and according to Tacitus' records, they felt that they were descendants of the Trojans.

The tutor taught the "little masters" when they were young, and became their servants when the "little masters" grew up. This is the tutor who once gave Georgiana a set of compasses and balances found in Pompeii. .

  Yes, science and technology is a force that promotes the progress of the times, even enough to disintegrate a country. Unfortunately, there are many people in this world who cherish the shell and throw away the nut. Rohart actually knows this well, even if he is a fraud, he is still a "Knight of Light" until the lie is exposed. In order to make the armor on his body stronger, he also put on the "badge" of the Anti-Dark Arts League.

  Reading is not useless, not that some people think it is so "all-powerful".

  When someone sees that some subjects are not valued or left aside, you study subjects that you think are valuable. This is a fantasy for the future. After graduation, you will find that those subjects that you once thought were valuable are no longer valuable.

  Learning real talents takes time and energy, and opportunism is not necessary. Few people are not jealous when they see others succeed, but if they follow him, it means losing the bottom line they have always adhered to.

There are real talents and flashy things to test. A scholar who is familiar with theology may not be more respected than an actor who can read a few lines on stage. A famous general may not be welcomed by people like a star walking on the red carpet. .

Learning so much is not as good as a pretty face, the necklace that ruined Marie Antoinette originally belonged to Madame du Barry, but the king died of smallpox, it was expensive enough to buy a warship, Marianne Toinette didn't ask for it.

  Life is like a play, and play is like life. The advantage of being indifferent to fame and wealth is that you don’t value those things. When you lose it, it won’t be as if you lost your life.

  Looking at the "stormy sea" in the glass tank, she thought of the Mediterranean folk song again:

   what the sea told you,

  You will engrave it on your chest

  until your soul returns to the harbor

   Waves oh waves,

   come one after another without hesitation

   Like my endless pain and sorrow

  The sea is as wide as the beach is wide,

  My longing is so strong,

  Intense enough that my frivolous joy is irresistible.

  I miss you so much, but do you miss me?
