Harry Potter Morning Light

The "Night" carved by Michelangelo for the Medici brothers' tomb is a sleeping woman, but her sleeping posture is very uncomfortable, and she looks like she is tossing and turning.

Under her mat is an owl curled up, and there is a mask with a surprised expression, which reminds people of the nightmares of the night. Anyway, she did not "fall asleep charmingly" as the poet wrote in the hymn.

As a sculpture in a cemetery, she makes the tomb owner look like he can't rest.

Michelangelo also wrote a poem:

Sleep is sweet, and it is happier to become a stone,

As long as there is shame and sin in the world.

Not seeing, hearing, and feeling is my greatest happiness;

Don't wake me up, speak softly.

"Night" lasted for a long time in Europe. Another group of sculptures, "Morning", seemed like Ariadne who had just woken up, struggling not to wake up from a sweet dream.

After Galileo, Newton also invented the telescope, but unlike Galileo's refracting telescope, Newton made a reflecting telescope. Compared with the refracting telescope, the reflecting telescope can magnify larger objects.

However, the image produced by the reflecting telescope is not as bright as that of the refracting telescope. Secondly, the high-reflectivity metal reflector required by the metal telescope is not easy to obtain, and it needs to be polished frequently, otherwise the reflector will gradually lose its luster. The refracting telescope can be used all the time, as long as the dust is occasionally removed.

The telescopes used by Hogwarts students are enough to cope with astronomy classes. If you are an astronomy enthusiast, you will go to the Muggle store to buy an expensive telescope. In the field of detecting the vast starry sky, Muggles are already ahead of wizards.

Severus has a "patent". Of course, applying for a patent is like a "joke" for alchemists. Only the Weasley brothers will apply for a patent for their daydream products.

Part of the work of an alchemist is encryption. In addition to the fact that if his encryption is cracked, it proves that he is not as skilled as others, and others can use his secrets without saying anything, there is also the addition of personal characteristics, such as the Parseltongue of the mysterious man.

Even if he was forging the Sword of Gryffindor, Severus couldn't have used a whole piece of goblin mithril, which was enough to make several Firebolts - Snape had disassembled Harry's Firebolt, and not only restored it intact, but also gave him a bunch of curses such as "expensive toys".

So he just plated a layer of mithril on the counterfeit Sword of Gryffindor. It not only looked like the same, but he also used this technology to make silver bullets that could kill werewolves. She didn't know what it was.

The last time Georgiana met Father Piazzi in Compiègne, he was the director of an observatory in Sicily, and went to England to visit William Hermann, because Hermann invented a new compound telescope, which had the advantages of both refracting telescopes and reflecting telescopes, but the disadvantage was that it was too expensive. Not only did he spend all his allowance, he also "married" a rich widow, so that he could make a telescope with a diameter of 1.22 meters. At that time, the telescope that Newton handed over to the Royal Society had a diameter of only 5 centimeters.

In order to climb up this "big guy" to observe it closely, Father Piazzi climbed up the scaffolding, but he fell from it and broke his hand, but he still managed to draw what he saw, and now the painting is in Father Oriani's hands.

Father Oriani is good at refraction. Although there is a big difference between atmospheric refraction and lens refraction, he "doesn't mind" using a better one.

In addition, he mentioned a young man named Fresnel, who worked with Fourier to propose a method to calculate aperture and diffraction, and calculated the aperture and diffraction of light.

It was enough to give her a headache to read calculus, let alone calculus plus functions.

Anyway, she didn't plan to use a whole silver plate as a reflective surface. It happened that she heard that Volta, a research institute in Pavia, had developed electroplating, and she wanted to see if she could plate silver on a metal plate, after all, they only wanted the reflectivity of the surface.

The first telescope Newton made was a mercury disk, and the effect was not ideal. Its advantage was low cost, and its disadvantage was that liquid mercury would evaporate during the day and solidify at night.

Solid mercury mirrors were still a top secret in Venice in 1688. The French sent spies and spent a lot of effort to bribe two defected craftsmen to steal the secret of the Venetian mirror. For this reason, Louis XIV even built a mirror hall in Versailles.

In Newton's time, the British had not mastered that technology. Ordinary glass mirrors also have a layer of glass, which has the same refractive index and light transmittance as the lens of the telescope itself, which is not suitable for high-precision instruments. The back of the mirror is usually not as reflective as the front, so Newton used a silver plate as the reflective surface for the second telescope.

Its advantage is that it is easy to grind and polish. Astronomical telescopes often have a curved surface rather than a flat surface. Mastering the curvature of glass manufacturing is much more difficult than manually grinding a silver plate.

It takes money to make a large telescope. If it is France to build an observatory, it is simple to use the money from the Sevres ceramic factory directly, but this is in Italy. Is it possible to use the money from the Bonaparte family bank?

"Why did you suddenly think of coming here?" Fredley said, standing next to a telescope, but looking up at the starry sky.

"I want to get some inspiration," she said, standing at the table, looking at the drawings of the Hermann telescope in front of her by candlelight.

"What inspiration?" Freddie asked.

She laughed.

There are many people who believe in astrology, including the kings who supported Tycho and Kepler, but astronomy is not the study of this.

"He told me that once the Vatican thought he was dead. What do you think it was?" Georgiana said with a smile.

"Stars?" Fredley tried to ask.

"No, they saw a shooting star and thought Napoleon had fallen like the star."

"Incredible." Frasley looked up at the sky again, "What if we encounter a meteor shower?"

Georgiana did not correct him.

After all, she was not sure whether the meteor that lit up the European night sky in 1812 would still reach the earth, or whether it was the comet that witnessed the defeat of Ramses II more than 2,000 years ago.

"You said that the people in hell are waiting for him because he is a meteor?" Fredley asked, "Just like Lucifer, he fell out of hell?"

"Do you think the light in Dante's hell represents hope, or does it want the people in hell to see clearly what they are going through?" Georgiana asked, "If it is darkness, you can't see anything."

"I never thought about it." Fredly said in surprise, "That light comes from heaven..."

"If you don't know what heaven is like, people in hell will take it for granted. Sisyphus is pushing a boulder every day. If he only knows this when he is born, it may not be so painful, precisely because he knows that there are flowers and grass. , which made him feel how tortured it was to push the stone," Georgiana said calmly.

Ron said in an interview that when Harry and the others flew out of Gringotts on their dragons, a beam of light came in from the sky, and that beam of light symbolized freedom and hope.

That dragon is so weak, how long can it live after returning to nature?

"A gentleman should advise you not to be so pessimistic." Fredley walked over slowly, "But I have bad news for you."

"Say it," she said in a challenging tone.

"Bodin provides the meat that the army needs. However, the meat they provide is rotten and cannot be eaten by humans. Moreover, Josephine also bought horses like you, but they cannot serve." Fred Leigh said "both she and Beaudin were charged."

"Me too?" She stroked her chest.

"At least the meat of those horses is fresh, and there are cans and stagecoaches. The woman I told you about last time wants to replace you with the Sèvres porcelain factory."

"Paris is about power struggle." She smiled calmly. "This is the difference between Britain and France."

Fredley smiled.

"Did you know that the German who competed with Soho to install street lamps used French technology?"

"What?" she asked in surprise.

"He applied for a patent, and Parliament actually approved it." Fredly sneered. "The Frenchman's name is Philippe Le Bon."

"Has he brought a lawsuit against you?" Georgiana asked.

"The question now is not this, Georgiana, how much did this war cost?" Fredly asked.

"Half of the 20 million francs was paid by Lyon," she said.

"How much benefit have you received?" Fredelli asked. "In order to reduce war taxes, the Florentines will always be empty-handed every time they see Josephine. I heard that the Florentines did not seem to support your plan very much at the meeting... About "Wheel."

"They didn't say they didn't support it," Georgiana said weakly.

Even if she "spends it as she pleases", how long will it take to spend 20 million francs?

Fredley stared at her.

"The tone is not gentle." She said it another way.

"What are you doing with a comprehensive tax on wheels?" Fredley asked.

"Building roads and protecting them."

Fredley sighed.

"We can cooperate on the wine tax, but it is impossible to withdraw troops from Malta. That is the heart of the Mediterranean." Fredly knocked on the table. "What on earth is going on in Gibraltar?"

"I don't know. I'm just responsible for passing on the message. They asked me to say it." Georgiana said, "I warned Meri to be careful."

"In 1786, France tried to enjoy most-favored-nation status in the Baltic Sea. Segur, the deputy envoy in London, was the provider of this plan. Do you know what that means?" Fredley asked.

"What?" she asked in English in surprise.

"The king didn't know about this. He was assassinated by a maid." Fredly sighed again. "I hope he goes crazy again."

"How did he handle it?" Georgiana asked.

Freddy looked at her strangely.

"I was not in England at the time," she said quickly.

"He handled the matter fairly, which aroused the admiration and loyalty of the people across the country. They felt that he was a reasonable person." Fredley shook his head, "Even if he is crazy."

Just as she was about to say something, there was the sound of a carriage outside, as if someone was coming.

"Wait here?" Fredley asked.

She looked through the telescope not far away.

If she had known this, she would have brought a deck of tarot cards.
