He was abducted by Hagrid when he turned 11 so that would place him maybe around the fifth or sixth grade.

I don't know if canonically there are math classes at Hogwarts.


The thought came to while I was watching the anime Mashle. If you are into Harry Potter and One-Punch Man I'd recommend giving it a watch.

I mean, there must be a reason why wizards are constantly perplexed by muggle technology.

[–] AbouBenAdhem@lemmy.world 100 points 9 months ago

And why goblins have to do their accounting for them.

[–] AFC1886VCC@reddthat.com 38 points 9 months ago (1 children)

The series would have ended much sooner if Harry had brought an AK47 to hogwarts

Although that could also be them being perplexed by the fact that muggles did it with no magic at all.

Imagine us discovering a species that developed computers and tech just like ours, but using neither transistors nor electricity.

[–] Vilian@lemmy.ca 10 points 9 months ago (1 children)

could hogwarts defeng itself against modern weapons? like missils and shit?

[–] FuglyDuck@lemmy.world 21 points 9 months ago (3 children)

Yeah. Easily.

Reducto or any of a dozen other spells that make shit explode, magical barriers, simply transfiguring the weapons to something else… telekinesis. Simply not being there.

And before you add “what if they were surprised…” …. It’s possible, but remember how shocked Hagrid was about the lie the Dursley’s told Potter? “A car crash?! A Car CRASH?! Kill lily and James potter?!….”

[–] SatanicNotMessianic@lemmy.ml 23 points 9 months ago (8 children)

I don’t know. I’ve always thought a sniper could have taken out Voldemort. Far away, camouflaged, and the bullet gets there faster than the sound. It’s a reaction time thing.

[–] Azzu@lemm.ee 24 points 9 months ago* (last edited 9 months ago)

Obviously, JK Rowling was not a tactical mastermind.

However in the universe she created, any powerful wizard worth a damn would simply keep protective shields up all the time, especially against such simple things like "fast objects hitting them".

Protego seems to be doing a lot with barely any effort to cast. Fred&George even create permanently enchanted clothing with Protego on it.

[–] FuglyDuck@lemmy.world 22 points 9 months ago (1 children)

I would expect Voldemort to have protective spells keeping things like that from happening.

If it were that easy to kill a witch or wizzard... then there's lots of ways to go about that. He wouldn't have needed a special wand to fight Harry. he'd just fling a ginormous rock out of nowhere.

[–] SatanicNotMessianic@lemmy.ml 14 points 9 months ago (4 children)

Well, we know that wizards are vulnerable to physical attack and to surprise attacks. There’s the whomping willow, which they can’t just cast a force field against. There were the spiders and the centaurs in the forest. The big three headed dog. That devil’s something plant. And if I recall, Voldemort didn’t realize the caretaker had come into the house until he was in the hallway and Nagini saw him. Sorry, it’s been a hot minute since I read those.

Wizards, one would think, could go flinging cars around whenever they wanted to, but they use death spells, even on muggles. Maybe they think it’s gauche to do something so mundane as dropping a rock on someone’s head, I couldn’t say. Jedi use the Force to throw things, but not to just crush someone’s head or rip it from their body. That would take a lot less force (so to speak) than lifting an X-wing, but they still use lightsabers.

And for what it’s worth, I think a sniper could take out a Jedi, too.

Hermione mentioned in the first book that wizards tend to absolutely suck at things that are typically Muggle, like logic, so it follows that they probably suck at math too.

[–] Sotuanduso@lemm.ee 43 points 9 months ago (2 children)

Logically, that does follow, but we're talking about wizards here.

I mean, the very existence of magic kind of nullifies the concept of math as a means to ascertain objective fact.

What good is 2+2 when 2 eyes of newt plus 2 legs of frog leads to random quantities of dancing forks with literally no respect as to the how because magic?

Math can't quantify a world where physical laws are replaced by literal nonsense, and if math could ultimately explain the mechanics of magic and predict the outcomes of its applications, the magic wouldn't be magic anymore, it would just be another great force of the universe like gravity or electromagnetism to be mapped by the scientific community.

[–] urist@lemmy.blahaj.zone 18 points 9 months ago

I always wondered the opposite of the harry potter universe.

So much of math was difficult to teach or obscure because of difficulties in visualization or computation. Surely there would have been at least one wizard over hundreds of years that could figure out how to use the powers of illusion magic to visualize things? To demonstrate integrals to the unfamiliar? To render a fractal like a julia set?

Even if magic iteslf followed little internal logic, it could be used as a tool, surely? But that's the sort of fridge logic (warning tv tropes link) that maybe didn't belong in a story book like Harry Potter. I had to stop reading anyway around the time house elves were introduced, anyway. I took issue with that stuff even when I was a kid.

[–] catonwheels@ttrpg.network 13 points 9 months ago (2 children)

Exactly what more than 5th grade math do you need in such world?

I think a lot of people forget what they learn in 5th grade math. You learn negative numbers. You learn unit conversion, fraction, prime, square roots.

Would more math help absolutely. Especially with the logic wizard seems to lack. But it is not like many people use higher level math today anyway.

"Arithmancy" is their name for math classes and is mentioned several times throughout the books. It is one of Hermione's favorite subjects.

At one point, the real world evil witch that is JK Rowling suggested that Arithmancy is like dviniation, but with math, saying they use numbers to predict the future. I take this to mean that the wizarding community discovered calculus independently from the rest of the world and mistook it for a new form of magic.

[–] master5o1@lemmy.nz 22 points 9 months ago

Divination with maths is statistics.

To be fair, I suspect the average adult in real life probably only remembers, and uses, 5th grade math.

Who needs math when you have magic?

[–] PlexSheep@feddit.de 11 points 9 months ago (6 children)

Who needs magic when we have science?

[–] the_q@lemmy.world 16 points 9 months ago (2 children)

Science: Here's why water is wet. Magic: I'm a dragon now.

My wife, who is a big potter fan, told me they take traditional classes as well, but they are shown off screen as they aren't interesting to the story.

[–] I_Has_A_Hat@lemmy.world 22 points 9 months ago

Pretty sure they explicitly talk about those kind of classes in the books. They don't have scenes in them, but I remember Ron and Harry complaining about arithmetic, or mathematics, or something like that.

[–] beefcat@lemmy.world 13 points 9 months ago* (last edited 9 months ago)

"Arithmancy" is what they call their math disciplines and it's mentioned a fair bit in the books, though understandably never really shown in the movies.

I'm sure Hogwarts also covered general education stuff but that would be boring to us so they focused on the magic stuff. That's my theory though.

[–] chaogomu@kbin.social 27 points 9 months ago (9 children)

They literally go through the class schedule in each book. General studies are not in it.

I’m just over here chuckling at your casual statement that Hagrid abducted Harry.

[–] joyjoy@lemm.ee 13 points 9 months ago

He broke down his door, mutilated his cousin, threatened his uncle, then lured Harry away with cake (which was eaten by said cousin).

[–] WastedJobe@feddit.de 18 points 9 months ago (1 children)

Isn't arithmetic a class in Hogwarts and just a fancy word for maths (not a native speaker)? I think only Hermione takes it though and it's only mentioned in the books.

[–] A_A@lemmy.world 27 points 9 months ago* (last edited 9 months ago)

arithmancy - which is pseudomaths in a sense....

[–] piecar@lemm.ee 12 points 9 months ago (4 children)

I think you're right. They probably don't know math. I mean, what would they need it for? They probably don't have to follow the laws of physics for the most part. If math is done it's probably 100% recreational.

So that would put him only a couple years ahead of most republicans

They have arithmancy but Harry never took it AFAIK

[–] UnPassive@lemmy.world 10 points 9 months ago (3 children)

Most of us only know 5th grade math
