Chapter 113
Next, Professor Sinistra gave a lesson to the young wizards...
Today, she mainly talked about the position of the earth in the solar system and the explanation of some proper nouns. Before get out of class, she also assigned a homework for the little wizards to look up the data by themselves to describe the position of the sun in the sky in a year.
There is no need to rush to answer this question. It is enough to submit the argument after Christmas. Submitting in the form of group cooperation is allowed.
The little wizards all looked confused: Isn't the sun on top of their heads?How would you describe its location?But since it's due after Christmas, don't worry!It's only September!The big deal is to find a young lady from Ravenclaw to do it together.
The ideas of little lions are always so cute.
Seeing that even Hermione fell into confusion, Lu Ren couldn't help sighing: This question is indeed beyond the outline.He learned this topic when he was studying photovoltaic cells when he was in college, but after so many years, he has already paid back the capital with interest to the teacher.
He only had a vague impression, "It seems to be using the yellow-red angle, is it the yellow-red angle or the effective angle..." Lu Ren muttered a few words in a low voice.
It's really annoying. In the previous life, there were special calculators to calculate these data. For example, some websites provided sun position calculators for free, but now they have to be calculated by hand.What's even more frightening is that if you push it yourself, the formulas involved will have to be calculated by hand...
Ordinary calculators cannot be used at Hogwarts, it seems that a mechanical calculator must be brought here, Lu Ren thought.
Electronic equipment must not be used at Hogwarts, but purely mechanical equipment is no problem.The peak of the development of mechanical calculators was in the 1970s, not more than 20 years from now, and you can still find them if you search for them in the non-magic world.Don't underestimate mechanical calculators. Addition, subtraction, multiplication, and division are not a problem, and some can take square roots!
With this, the calculations in astronomy class can be much easier.
However, Lu Ren hoped from the bottom of his heart that these calculations would not be involved in the future.Otherwise, the easiest thing is to let you calculate how much sin 7° is equal to, and all the little wizards present will have to stop.
Hermione heard Lu Ren's soliloquy, and she frowned tightly, with a look of incredulity on her face: "Lu Ren, do you know how to do the question left by the professor?!"
"I know the general steps, but I need to check the information," Lu Ren said frankly, "and the amount of calculation is huge, I'm afraid it will be very troublesome."
Hermione raised her eyebrows, tapped her fingers on the table a few times, she hesitated for a moment, "Can... can we, do it together?" She suddenly whispered such a sentence.
At this time, Lu Ren was searching for knowledge from more than ten years ago in his stomach, and he didn't hear Hermione's whisper at all. He subconsciously raised his head and asked, "Sorry, what did you say?"
"I want to do it with you. Can I do it?" Hermione also straightened her mind: People are not born with knowledge, so who can be free from confusion?If you are confused and don't follow the teacher, you are confused, and you will never understand it.Of course, Hermione didn't know this ancient text, but she understood the truth in it.
Study well, don't be shabby!
"Oh! You want to do that with me!" Lu Ren reacted, "Yes, it would be great if I could do that with you!"
If you must do it with other people, then Hermione is definitely the perfect object, and it must be very cool to do it with her.At this time, Harry and Ron also noticed that the two top students next to them seemed to have reached some kind of special friendship deal, and as ordinary students, they also made a decision in an instant.
In school, if you want to get along, you must have the ability.This kind of ability is either reflected in academic ability or in interpersonal communication ability-that is, the ability to hug the thigh.
And the two thickest thighs in the class are already entangled, so in this case, it is natural to hurry up.This kind of pendant position on the thigh is as rare as a Shanghai brand.Ron and Harry showed the same spirit as the South Vietnamese in Saigon in 1975 to snatch air tickets to other countries, and quickly booked the members of the group.
Naturally, Lu Ren readily agreed: With Hermione in the team, the project could be completed steadily, so it would not be a problem to bring two acquaintances along.
So three boys and one girl decided to do it together.
At this time, Lavender also appeared next to Lu Ren, and asked casually, "Can you add me? I want to do it with you too~"
Lu Ren thought about it and decided to decline her.
So he said, "No. The group is full."
Lavender: ...
There is one thing to say, indeed.Although Professor Sinista did not specify the number of people in the group, the group of four already exceeded the limit. With Lavender added, will her friend Parvati Patil be added?That's a group of six...
You might as well get the whole Gryffindor first-year team!
Lavender didn't expect to be rejected at all, and he froze there.
Lu Ren apologized, "I'm sorry, our group is indeed full, I'm sorry."
Lavender did not respond, and her friend Parvati rushed to drag her away.
This was just a small episode, and Lu Ren didn't take it to heart.Instead he was discussing the project with Hermione.
There was a slight disagreement within the group about when the project should start, and Hermione wanted to start as early as possible, preferably today if possible.And Lu Ren felt that there was no rush for this thing!Are you exaggerating now that you don't hand in things until after Christmas?And where can I find the required formula?library?There is no textbook for astronomy class!
The library is so big, even if Mrs. Google Pince is humanoid, it would be a big project.As for these formulas, Lu Ren doubts that he will learn them in the following courses...
So it makes perfect sense for this project to drag on for a few days!
Since the astronomy class started late, it was already nine o'clock in the evening. Naturally, we couldn't continue to wander around the campus, otherwise it would not be fun to be caught by Filch, not to mention the library, which is helpful to them. Also closed.
So even if you want to start working on the project, you have to wait until tomorrow...
Hermione, on the other hand, has an "I'm going to die" look, as if starting a project a day late will delay the project.
Lu Ren had no choice but to coax Hermione for a long time before he believed him.Let Hermione agree to wait and see first, and wait until the class is over next week before considering whether to start the project.
But he didn't keep Hermione waiting, he suggested that Hermione contact her parents, and hinted that she might have a miraculous effect...
There is nothing wrong with it!The project left by Professor Sinista will only take about 5 minutes for non-magical astronomers to answer.
Once the conflict within the group is resolved, the day is over.
