Chapter 112 Late Night Astronomy Class
Every Wednesday night, Lu Ren and the others have astronomy class.This subject is a core subject taught at Hogwarts, meaning it is compulsory until fifth year.Astronomy is the study of the orbits of the stars and planets, but in this course students don't need to use any practical magic.
The professor of astronomy is Aurora Sinista, a beautiful black witch.The class is held in the Astronomy Tower, which is also the tallest tower in Hogwarts.
Due to the cancellation of the class last week, it was the first time for Lu Ren to come to this tower.
Thanks to the movie cuts, the astronomy class has a pitifully small number of roles in the seven movies, and the history of magic, Muggle studies, and digital divination are almost as good as it.And everyone's impression of the Astronomical Tower probably comes from the last clip of the sixth movie.
Stepping into the tower, Lu Ren felt a little emotional.If he doesn't show up, Dumbledore will die here six years later, and Grindelwald will die silently in Nurmengard in another year.
The outer wall of the tower is the kind of gray-yellow brick in the white of Hogwarts Castle, while the interior is covered with the same wooden floor as the plank road in tourist attractions.Going around several spiraling stairs and coming to the top floor of the tower, you will find that the top of the tower is divided into two parts.
There are many astronomical instruments piled up in the lower part. Lu Ren looked at the old traces and dust on it, and felt that he should not use them in a short time.There are also desks in the room, and Professor Sinista's class is on the lower half floor.The upper part is quite open. First of all, there are no windows at all, and only a few columns supporting the top of the tower are left on the wall.There is nothing between the pillars, this design is convenient for little wizards to watch the sky from here at night.
When Lu Ren and the others arrived, Professor Sinista was already waiting in the tower.
Seeing that everyone was here, she waved her magic wand lightly, and all the candles and braziers in the classroom burned, making the whole classroom brighter.
"I am Aurora Sinista, and I will teach you some basic knowledge of astronomy in the next five years. I sincerely hope that you can pass the OWL exam, and then continue to study this profound subject in the sixth and seventh years. subject." Sinista's voice was nice, although she had a little French accent, it was very crisp.
"We don't need silly wand waving here..."
"Then why did you wave it just now..." Perhaps because of being infected by Lu Ren, Ron also became fond of complaining, and he muttered in a low voice.
"Five points deducted from Gryffindor, next time I hear you argue, I'll ask you out." Sinista suddenly interrupted the course introduction.
Ron: (⊙﹏⊙)
Ron looked like he was being fed a fly.But he really didn't dare to talk anymore.
'This teacher's hearing is very keen. Lu Ren sighed, but with Ron's lessons learned from the past, he only dared to keep this sentence in his stomach.
"Put away your wands, we only need to use the telescope to observe the starry sky, and I will teach you the trajectories of different stars and planets in the next five years. At that time, you will discover the depth and mystery of this universe, You're going to love it."
If one had to choose which Hogwarts class was most similar to Muggle classes, then Lu Ren would vote for the astronomy class.This subject is not fundamentally different from Muggle astronomy except that the equipment lags far behind the non-magical world.However, it should be noted that astronomy is divided into two branches: observational astronomy and theoretical astronomy.Observational astronomy focuses on obtaining observational data of celestial bodies, and then analyzes them based on basic physical principles; theoretical astronomy develops computer models and analytical models for analyzing celestial phenomena.
There is no doubt that astronomy in the wizarding world belongs to observational astronomy.Before the fifth grade, this course tends to be in the field of popular science. After the fifth grade, this course will be related to astrology and divination.
However, what Professor Sinista said next made Lu Ren a little interested in this subject.
"Perhaps all of you here have Muggle-born wizards. I hope they don't confuse Muggle astronomy with wizarding astronomy. There are some differences between the two, such as the planets in the solar system. Muggles generally believe that there are nine planets. , but the wizarding world only recognizes eight of them."
Lu Ren:! ! !
Fuck, this was the first time he'd seen the wizarding world surpass the non-magical world in the field of "science". In the 20s, people still generally believed that there were nine planets in the solar system. It was not until 90 that the Muggles officially downgraded Pluto to a dwarf planet.
As a result, wizards have already discovered this thing?
There is a rigorous scientific basis for Muggles to downgrade Pluto.To become a planet, three conditions need to be met: 1. It revolves around a star (the sun in the solar system) in an approximately circular orbit. 2. The mass is large enough to make the celestial body into a spherical shape by its own gravity. 3. Able to gradually clear other objects near its orbit.
Pluto is planted on 3, and of course 2 is not very close.It is only one-third the size of the moon and only one-sixth the mass of the moon.
The key problem is that Pluto cannot clear its orbit of other objects, and it forms a binary system with its own planet Charon.This is the main reason it was downgraded.
What about the wizarding world?
Lu Ren raised his hand to ask this question.
Professor Sinistra glanced at him, "The predecessors in the magic world learned that by analyzing the few words left by the ancient wizards, some divination omens can be obtained by calculating the trajectory of each planet. But the calculation results are always different from the actual ones." The gap. Later we found that the correct answer could be obtained by simply removing Pluto, so the predecessors expelled Pluto from the planets."
"Okay, I used this example to prove the difference in astronomy between us and Muggles. You can go to the divination class to learn specific knowledge. Let's stop talking about these gossips. What I want to teach you as the first lesson today is Something about the planet beneath our feet..."
It turned out that it was related to divination, and Lu Ren roughly understood the reason.The big wizard among the wizards found that although this thing looks like a planet, bringing it into the calculation will always interfere with the calculation results, so he kicked it out of the "planetary group of the solar system".
The wizarding world can always surprise you!Lu Ren was delighted from the bottom of his heart. This kind of experience of gradually unveiling a mysterious and unknown world is always exciting.
This is what drives him to keep going.
Side note: Speaking of Grindelwald's death, I think this is where the Harry Potter directors made a terrible adaptation.In the movie, Grindelwald actually quickly told Voldemort the whereabouts of the Elder Wand! ! !That dialogue lowered Grindelwald's compulsion.
Look at the original text:
"Here you come, I thought you would come one day...but your trip is meaningless because I never had it."
"Kill it, Voldemort, I'm glad to die, but my death won't get you what you want. There are many things you won't understand."
"Kill me, you won't win, you can't win, that wand will never be yours and never will be."
Watch the movie again: "Of course the Elder Wand is with him... Dumbledore!" (I really don't want to put the whole dialogue up) If you want to watch the original video, go to Station B Ha7, 1 hour and 59 minutes.
Gee.
Give an inappropriate example.This adaptation directly pulled Grindelwald from the rank of hero to the level of Gaddafi.What does the passage before his death in the movie express?Revenge on Dumbledore or trying to survive?
