Y'all motherfuckers lying, and getting me pissed

No. Does that mean I can stay after class for special lessons?

Going out of my room?

You may.

Yes.

There are 11,520 kinds of supernatural creatures in the world.

^what I learned

I have learned and tried to memorize the exact exchange of words that took place on the bridge of the Bismarck prior to the battle of the Denmark Strait in which "the mighty" HMS Hood was sunk in one hit after a mere three minutes.
But unfortunately I don't know German.

And you know what the worst part is

I still don't know how FUCKIN MAGNETS WORK.

Oh shi-

Probably not a good time to cast Magic Missile.

Well, since this is an infodump thread, I'll go ahead and say there really ought to be a VN where you play as Abe no Seimei, except everyone (including Seimei) should be girls.

>Seimei was once seated in his official place at the Palace, watching the high court nobles arrive with their fine array of outriders, when he saw an elegant and very handsome young archivist minor captain alight from his carriage and enter the palace. Just at that moment, Seimei saw a crow fly over the officer’s head and drop its dung on him. Seimei took a careful look at it and thought to himself, “What a shame that such a handsome and very popular young man should have been attacked by an evil spirit! This crow is clearly some diviner’s familiar.” Evidently it was not the officer’s destiny to die yet, for Seimei felt so sorry for him that he went over and asked him, “Are you having an audience of His Majesty? Forgive me if I seem a little presumptuous, but why have you come to the palace? I have seen signs that you will not live through the night. Fate willed that it should be revealed to me. Please come with me and let me see what I can do.”… With the minor captain clasped tightly in his arms, Seimei cast spells to protect him, and all night long, without a moment’s sleep, he never once stopped reciting incomprehensible incantations and prayers.

>>4880225
>It was a long autumn night, but he concentrated his efforts, and towards dawn there came a knocking at the door. At Seimei’s suggestion, someone was sent out to see what it was, and it turned out to be the familiar who had been brought down on the minor captain by his brother-in-law, who had held the archivist’s Fifth Rank. They lived in different parts of the same house, and the minor captain’s brother-in-law was jealous because their father-in-law had a poor opinion of him, while he was very pleased with the minor captain as a son-in-law and made a great fuss of him. The brother-in-law was so jealous, in fact, that he had engaged a diviner to bring this spirit familiar down onto his rival. The minor captain had thus been close to death when Seimei had observed him, and after Seimei’s night-long praying, a messenger had come from the diviner, who had brought down the evil spirit and announced in a loud voice, “Foolishly, and without reason save that I had been commanded to do so, I brought down an evil spirit on you, but you had such strong protection that it has turned back on me and I have now been struck dead, as a result of the awful thing that I did.” “Do you hear that, sir?” said Seimei, “If I had not discovered this last night, that is what would have happened to you.” The messenger was sent back in the company of a servant, who on inquiry was told that the diviner’s death had been instantaneous. The son-inlaw who had engaged the diviner to bring down the evil spirit was immediately sent packing by his father-in-law, who was overcome with tears as he thanked Seimei, and was scarcely able to reward him handsomely enough to express his gratitude

I wish I was a young girl with a half-fox onmyouji onee-sama standing beside my bed chanting prayers all night to save me from malign spirits ;_;

>>4880225

GOD DAMN IT.

Pop quiz:

Cirno writes 5+5+5 = 550 on the board. Keine headbutts her and, adding just one line, makes the equation correct. How? (no, not the inequality sign)

>>4880280
It's an Identity proof, if you mean there are three lines between the answer and the equation right?

>>4880286

A "line" as in "one short, straight stroke with a piece of chalk" either on the left or the right side of this equation.

>>4880280
Turn the + into a 4.

>>4880321
Oh shit man, I didn't think of that.....

>>4880321

I guess it was just too easy. Here's another (rephrased) classic:

Youmu opens a window on the 34th floor of Hakugyokurou (let's say there is one) and jumps through it. There's nothing but sharp rocks on the ground outside. She had nothing to slow her down or cushion her when falling, yet she escapes unharmed. How?

>>4880445
Everyone in Gensokyo flies except Akyu.

>>4880445
She is half ghost. So she's unharmed.

>>4880445

Too soft

>>4880451

I just realized that.

Wow.

>>4880445
she's the softest

>>4880451
>>4880455
>>4880457

3 headbutts. She was in free fall after the jump, and Myon didn't try to save her from the fall.

>>4880470

We've been over this before.

Youmu is not the softest because she uses swords. That means she practices with swords. People who practice with swords get cuts and scabs all over their skin.

She's disgusting, in other words.

Patchy may be the softest, actually.

>>4880480
heresy

>>4880478
You never removed flying from the original equation.

Anyway, a second answer is "she jump through the window into Hakugyokuro."

>>4880445
She was outside window and jumped inside?

>>4880445

Isn't it obvious?

>>4880480
Your stereotype offends me. You don't have to cut yourself or others to practice swordplay. The only thing that happens is that your hands get weathered over time. Depending on which type of swordplay you are learning, even that might not happen. Modern fencing, for example, uses thick gloves that protect the sword hand from getting cut or pummeled, so your sword hand can remain soft and smooth. Though, I would be lying to say that you can't get hurt through the glove, since I've been bleeding and bruised on my right hand from fencing many times.

>>4880526
SAGE SAGE SAGE B&OOORING!

>>4880526

Youmu practices in a garden with two swords and no gloves. In fact, she just have a short shirt. She's bound to get cuts the way she flails her weapons around. Plus the friction of swinging will create blisters.

>>4880518
>>4880517

That's what you were supposed to answer. Another one? (also somewhat modified)

Marisa went book-fishing at SDM again, and got 3 books, each having a mass of 1kg. In order to escape from Patchouli, she needs to cross a bridge that can only hold 40kg (it's an old, crappy bridge, okay?).

Unfortunately, she left her broom at SDM and cannot fly. She safely walks over the bridge with all the books, anyway. Given that Marisa is 38kg (clothes, etc. included), how did she do it?

>>4880555
She went naked, shedding 1kg of clothing

YOUKAI GO TO HELL

>>4880555
By your wording I'm guessing she didn't throw them across?

>>4880561
>>4880565

Nope, no time to undress. All clothing remained intact, and the bridge was too long to throw the books over or jump over it.

>>4880555
she took 2 books and crossed, then she came back and took the last one and crossed.
Mr.Obvious saves the day!

>>4880555
Magic?

>>4880590
If she had enough time to do that, she had enough time to undress.

>>4880005
Damn Arc
How'd you get so chill?

>>4880590
Nice guess, but wrong. She took a 1kg shit before crossing with all 3.

>>4880555
>>4880561
>>4880590
>>4880591
Am I really the only one who's heard this riddle before? The answer is she juggled it.

>>4880607
How does taking a 1kg shit will help someone lose weight...?

>>4880445

1) She jumped in through the window, not out of it.

or

2) SHE CAN FUCKING FLY

>>4880591
>>4880590

No magic, and no, she only crossed the bridge once.

>>4880610
PHYSICS DOESN'T WORK THAT WAY

>>4880610
I was going to say that but throwing a book upward would cause it to break if it's that close.

>>4880610
PHYSICS DON'T WORK THAT WAY

>>4880616
She threw the books across?

Can't she go back and get her damn broom back?

I mean she has power to beat them over again...

>>4880555
She used Blazing Star.

>>4880618
I'm pretty sure that by juggling three 1kg weights, you never actually hold more than 1kg at a time.

>>4880628
Disregard that, I didn't read all of it.

Uh..she took the pages out?

>>4880627
>>4880618
And bridges don't have critical weight limit failures. What's your point?

>>4880610

Yeah, I'm pretty sure it's a classical one, and yes, that's the normal answer. I just read it in Touhou context before and decided to reinterpret a bit :)

>>4880618

Oh come on. Technically, yeah, it depends on how high she juggles, etc., but it's supposed to be just a cute little riddle....

>>4880640
The bridge still has to support all 41kg. Tossing the books up causes the displaced air to push down with exactly equal force.

>>4880616
She reads the books, and learns a new flying skill.

And flies.

>>4880555
>Given that Marisa is 38kg (clothes, etc. included)
>etc. included
Don't tell me she just walked across because she was under the weight limit...

I LEARNED HOW TO STICK MY DICK INTO THAT CAVE YOU CALL A VAGINA, THANKS, SLUT!

>>4880665
>under the weight limit
Well, she's a loli anyway.

>>4880555
>Given that Marisa is 38kg (clothes, etc. included)
if it's everything included she's fine and can walk accross

damn that's light, even for loli marisa.

Thank you Keine-sensei, i now know that inertia is a property of matter!

>>4880665
>>4880658

The canon answer, as posted above, is that she juggled while walking.

>>4880651

Huh? The effect due to displaced air (if any) would be negligible, the issue that people brought up is the reaction force when she throws the book up.

Though if she only throws up one book at a time with accel. no faster than g, shouldn't that still work?

yo bitch, how da fuck magnets work?

DON'T TELL ME, YOU MAKIN ME PISS.

>>4880671

>CAVE

>>4880693
Regardless of the acceleration she throws the books up at, the bridge will collapse. Just holding the books, she's exterting an upwards force of 9.8 N. Tossing them upwards will only increase the upwards force she's exerting, and correspondingly the downwards force the bridge experiences.

>>4880658
Marisa doesn't need her broom to fly.

Ergo, this is a pointless exercise. She would simply fly.

>Though if she only throws up one book at a time with accel. no faster than g, shouldn't that still work?

nope

1 book in air, 2 books in hand = 40kg
accelerates one book upwards at g, reaction at her feet to counteract the force applied to the book of 1kg weight force.

She now weighs effectively 41kg.

Bridge collapses

where the Haku-bitch teacher go?

>>4880751
>bitch
You take that back.

OP here. Again..... What happened to this thread?!

>>4880747

I'm no juggling expert, but if juggling 3 objects, aren't you supposed to throw one *just* as another one starts to land?

If you throw with one hand before the other hand stops moving, I can see this still being feasible.

>>4880782
YOU STILL DIDN'T TELL ME HOW FUCKING MAGNETS WORK, BITCH.

>>4880747
Except that when juggling, you only have one book in your hand at a time.

>>4880782
what precisely were you expecting? tbh, I was hoping for a keine image dump.

>>4880805
OP again. This was what I was expecting. Not a logic thread.

>>4880813
Never too late.

>>4880803
>>4880788
If you are juggling with 2 things constantly in the air the Absolute minimum rate which you can accelerate the one thing in your hand is 2g.

one marisa and one book is 39kg

2g acceleration = 2kg weight force

effective weight of 41kg

bridge collapses

>>4880822
Bah, they've got a discussion going. Let em talk, make a new thread.

>>4880853

They changed the topic of the thread though.....

I can see where you're coming from with all of these answers, I'd accept your answer if this were a game or something.

The riddle itself was one of Gollums' from The Hobbit, Sakuya was a clue.

>>4880955

Obviously, time. Jeez. Touhou-related and less obvious, please.

Poster of the first 3 riddles here.

Don't have any more good ones, so here's the last one. I'll let you guys take over.

At 6 years old, little Reimu measured her height against a big tree near the shrine and hammered a nail into it (the tree, that is).

10 years later, she returns to the tree to see where the nail is now. How much higher did it get? (very approximately, assuming the ground is where it was, etc.)

>>4881018
The nail is in the same place.

>>4881018

Change in distance = height gained by tree in 10 years.

>>4881018
Why would it move upwards at all?

>>4881035

This should be the right answer. Trees are supposed to grow up from the top (or buds, or whatever) and expand in diameter, so the nail should stay pretty much where it was.

Your turn, /jp/...

>>4881046 height

width I mean

Whatever

>Still don't quite see how, maybe I'm slow...
For every book there are three phases when juggling

1. Up phase
2. Down phase
3. Hand phase

At all times each of the three books are in one of the phases, one in the first, one in the second, one in the third (if we are talking about a situation where you throw up book just as another lands in your hand).

In this case all 3 phases must last for the same amount of time.

When the ball is in the up and down phases it is in free fall so we can call the acceleration it does 2tg (2 time phases x gravity).

During the hand phase the net acceleration it does during this time must be equal to 2tg to keep the system stable.

While holding the book gravity is still acting on it so marisa has to exert g on it just to stop it continuing to free fall, to reverse the velocity of the book she must additional input 2tg of acceleration into the book so it leaves with the same speed that it landed in her hand with.

Because she cannot increase the length of the period she must exert and additional 2g of force to achieve the same net acceleration the book experienced during free fall.

So the total force she applies to the book during the hand phase is 3g (1g to prevent the ball from continuing free fall + 2g to reverse the velocity of the ball in the time frame.)

Because she is exerting 3g of force onto the book while it is in her hands the book is effectively weighs 3 times it's usual weight, so the book effectively weighs 3kgs while she is juggling it.

>>4880599

>How'd you get so chill?

It's all part of my natural player essence, man. I'm glad you like it.

I just got back from the gym and this thread's still here. Neato.

>>4881230

This explanation sucks, but the result does seem to be correct.

The whole thing hinges on the assumption that she has t=the time needed for a book to reach the highest point=time it needs to come down (although I can't really think of pattern where this wouldn't be the case). Also, t=v/g, where v=the speed that the book left her hand with (and which it will have just before landing).

To stop the book on landing, Marisa needs to impart an impulse I=mv=mgt (as per above). This means she will need to apply a (constant) force F=mgt/delta-t, PLUS mg to counteract gravity. We can only allow 2mg before the bridge collapses, thus delta-t will have to be at least =t, meaning she'll have no time left to actually throw the ball.

Another major assumption is that this is all rigid-body, frictionless collisions. Somebody else could propose a model with springs and whatnot...

>>4882096
>meaning she'll have no time left to actually throw the ball.

Gah, that should be "book", of course...

She could have tied a rope to the books, walked over the bridge, then pulled the books over.
