Chapter 2940 Don’t ride on the wind (7)

The Great Hall of Hogwarts has many functions, but it is most often used as the "canteen", and there are very few opportunities to hold serious "ceremonies" throughout the year.

It was always filled with the smell of food rather than spices. Perhaps once, when Dumbledore was the Transfiguration teacher, there was a Fountain of Luck in the school because Kettleburn dressed the Ash Snake as an earthworm.

, and then the entire auditorium was set on fire.

For a while, the "auditorium" was filled with a burning smell. The long wooden table used in the fourth courtyard was also burned, and it was no longer the original one. The new wooden table was painted with a layer of fireproof wax and looked very beautiful. The original one was

The long table has become very worn out after so many years of use, but people still miss the old table.

Someone even found graffiti on the table from their great-great-grandparents, who once were as young as their grandchildren.

But this is not the issue to be discussed at the moment.

There was an episode in that accident. The "Unlucky Knight" fell in love with "Amata" and "Asha" respectively. They could barely restrain themselves at first, 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 issue of a partner for the Celestial Ball. First of all, he and Gryffindor's "Amata" were friends, and he really liked

It is Hufflepuff's "Asha". During the period when the portrait curse appeared in the school, he served as "Asha"'s bodyguard and felt something that could not be felt from "Amata".

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

It was precisely because "Asha" knew about this relationship that she saw "Unlucky Knight" and "Amata" having sex and didn't think there was any problem. It went on like this for several years without incident, until the celestial body

When a dance partner was invited to the dance, "Amata" noticed the existence of "Asha", and then they started fighting.

After the incident, the "Unlucky Knight" immediately cut off contact with "Asha", but he did not stay with "Amata" either. He would rather play with his "brothers".

This matter has always been forgotten, although occasionally "Asha" and "Amata" meet in the auditorium or other places, their eyes only meet, and the air is full of fire and lightning.

"Amata's" attack was not directly related to Emily Taylor. It was members of her inner circle who fanned the flames in "Amata"'s ears, and then "Amata" and "Asha" were in the auditorium

He started yelling and cursing, and Pomona happened to see that scene when he entered the auditorium.

The layout of the headmaster's table is roughly like this. The Gryffindor and Slytherin tables are on the outermost side, with Ravenclaw and Hufflepuff in the middle. But this is not absolute. Occasionally the headmaster will arrange other tables.

Next time, the prefect will receive the message in advance and then sit at the assigned long table. The other students will sit wherever they see the prefect.

In other words, when "Amata" and "Asha" were quarreling, there was a long Ravenclaw table in the middle. When "Amata" and "Asha" took out their wands and shot at each other, a Ravenclaw

Crow's boy was hit by the hair curse and he's in the hospital wing now.

When Bill said that he saw clearly what kind of person Emily was, Pomona wanted to help her out, but when she saw the chaos around her and Emily and the gang members laughing so happily, she

What little empathy I had was gone.

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

The Joker said on the Morrie Show that no one has any manners at all (civil).

Both civil and polite mean politeness, but they are different.

Emily's table manners are good and she looks very elegant, but her "civil" is very bad.

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

"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 their own small sailboats in it.

The Brussels Museum didn't have that much space for the children to put the boat, but they made a large glass tank. Through the glass tank, you can see the boat in the water. Fresnel was explaining it to the children.

Dolphins are very smart animals. They know how to follow human ships and move forward with less resistance. Most ships currently use forward-inclined bows. Although there is a certain angle between the bow curve and the water surface, the oncoming ships

After the water flow hits the bow, the water pressure on the impact surface will increase, and after the high-pressure area is removed, the water surface will fall again, thus forming wave-making resistance.

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

Napoleon happened to encounter a storm when he led his troops from France to expedition to Egypt. 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 seasicknesses as last time.

Vitruvius has discovered "interference waves". For example, if two stones are thrown into water, the two will superimpose and weaken. If the first sound is not blocked, the second sound will not be blocked.

When it reaches the obstacle, the highest and lowest points reach the ears and there is no echo at all.

The opera houses in ancient Greece did not have a roof, which tested the singer's lung capacity because the sound would diffuse out. This not only avoided echo interference, but also reduced the direct sound that the audience could hear. The buildings in the opera houses with roofs were

Consider echo and reverberation, which is undesirable.

To eliminate wave-making resistance, the best way is to add a wave. When the wave crest and wave trough meet, the wave-making resistance crest will be reduced, thereby increasing the ship speed and passenger riding experience. But how to design this offset?

What about the waves used?

If the sailor knows the speed and direction of the ocean current on a route well, he can add a bulge on the bottom of the ship. This protruding body will form a wave when moving forward. When the wave speed and wavelength are within a certain range, the wave resistance can be reduced.

But this means that the speed cannot be too fast or too slow, otherwise the protrusion will fail.

This kind of ship will be on routes that operate all year round, and it will only be used before the age of sails. At that time, ships in the Mediterranean still relied on human oars. Even if the lives of the slaves who rowed the oars were not taken seriously, this kind of "force majeure" would still have to happen.

Concerned, when the war is fierce, soldiers will be needed to row. The main function of the battleship is to carry soldiers rather than slaves and goods.

Around 50 BC, the main battleships of ancient Rome followed the ideas of ancient Greek battleships, but they changed the protrusion on the bow into a wolf head, which was more decorative.

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

The tutor teaches the "little master" when they are young, and becomes their servant when the "little master" grows up. This is the case with the tutor who once gave Georgiana a set of compasses and scales found in Pompeii.

Yes, technology is the force that promotes the progress of the times, and can even disintegrate a country. Unfortunately, there are many people in the world who cherish the shells and throw away the nuts. Rohart actually understands this very well. Even though he is a deceitful person, in this world

Before the lie was exposed, he was still a "Knight of Light". In order to make his armor stronger, he even put on the "badge" of the Anti-Dark Arts Alliance.

Reading is not useless, and it is not as "all-purpose" as some people think.

When some people see that some subjects are not taken seriously or are put aside, they study subjects that they feel are valuable. This is an illusion about the future. After graduation, you will find that those subjects that you once felt are valuable are no longer valuable.

It takes time and energy to learn real skills, not opportunism. Few people are not jealous when they see others succeed, but if you imitate them, it means losing the bottom line that you have always adhered to.

There is a need to test whether there is genuine talent or flashiness. A scholar who is familiar with theology will not necessarily gain more respect than an actor who can recite a few lines on stage. A famous general will not necessarily be welcomed by others like a star walking on the red carpet.

Learning so much is not as good as a beautiful face. The necklace that ruined Marie Antoinette originally belonged to Madame Du Barry. However, the king died of smallpox. It was expensive enough to buy a warship. Marianne

Toinette didn't ask for this.

Life is like a play, and play is like life. The advantage of being indifferent to fame and fortune is that you don't value those things. When you lose them, it won't be like losing your life. It has nothing to do with high moral character. Will you feel bad if you lose half a penny?

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

What the ocean tells you,

You have to engrave it on your chest

Until your soul returns to the harbor

Waves, waves,

Come one after another without any hesitation

Like my endless pain and sorrow

How wide is the sea and how wide are the beaches?

My longing is so strong,

It was so strong that my frivolous joy was irresistible.

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