Conceptual Limitation

This is another piece of fan art that I did for the only fanfiction I really like: Harry Potter and the Methods of Rationality.

This is about chapter 28 when Harry transfigures only a piece of an eraser, but forgets some important rules.

Like watercolor, marker is not my medium. I'll have to keep looking.

The table is not described in the story so I decided it was covered with a white table cloth.

Comments and criticism welcomed, if I know what I've done well and what I've done horribly, then I can do better next time.

Also credit must go to my older brother for finding me the time independent Schrödinger equation with arbitrary dimension. Also for teaching me that phrase.

i love the fact that you wrote an actual Hamiltonian out, very nice my friend.

(but there's supposed to be a minus sign in front of the h-bar^2)

I'm still not quite sure I understood what actually happened in that scene...

Transfiguration magic doesn't allow "part of an object" to be transfigured, and that's linked to what you consider to be an "object". So wizards can't transfigure "part of an object" because to them, an eraser is definitely a "whole object". Harry tries to transfigure part of it by reasoning that the "whole" eraser is made up of tiny atoms and quarks (panels 2 and 3) that are definitely separate objects. When that doesn't work, he realizes that quarks and atoms are just things reasoned out by scientists to explain how matter is formed. His next try is more abstract. He visualizes the universe as hazy, undefined waves of matter that sometimes bunch together into what normal wizards call "whole objects", but can come apart just as easily, so really nothing is a whole object. (panel 4) That's when it works.

Okay, I think I've got it! Thank you, you really explained that nicely :3 But... why did Hermione panic? :/

basically, Harry was literally poking the fabric of the universe with a stick to see what would happen.

NOW do you realize why Hermione might panic? xD lmao.

I mean, sure it was a MAGIC stick, and he was PRETTY sure he knew what he was doing....oh who are we kidding- HE'S ELEVEN YEARS OLD! even if he's smarter than Artemis Fowl and Jimmy Neutron put together- he STILL should. NOT. be. DOING. DAT! xD

Don't you remember when he was 'doing math' with that Time Turner? yeah....srsly, I am actually surprised he hasn't yet turned Hogwarts Castle itself into a CRATER. xD xD xD

When he actually manages to change the spot on the eraser its by (increasingly simplified) thinking of the universe as math, and not just as what he could see or imagine as a picture.

They've also transfigured a piece of thread into a bit of carbon nanotube, and they left it hanging while it was still supporting a large weight.

Right answer, just incomplete. I don't remember the exact details, but I doubt they transfigured the thread into exactly one carbon nanotube. If one such thing breaks, nano particles fly and the weights drop. Fine. Harry then Finite Incantatems the tranfiguration after getting out of the classroom space, thru a small opening, so that he doesn't breathe these particles, which could end up in his blood. But the thread I believe was transfigured into a bunch of parallel nanotubes. If only one broke (much like a thread fraying), Harry wouldn't know. And then Hermione realized.

It's been a few months since I read it, but I think it was because she didn't really understand what Harry was doing, and didn't want something horrible to happen because of experimental transfiguration...which Harry should have thought of too.
