That just doesn't feel like how Remembralls work, though. For one, "forgotten something" involves having known it: using Aristotelian instead of Newtonian physics seems like a mistake, not a forgetting. Like, if he had learned through some comically painful experience that broomsticks did indeed follow Newtonian laws, and then put a rocket on his broomstick: I would expect the Remembrall to be glowing this brightly at this point.
For two, a simple magic item that works exactly as intended, no matter how trivial or gigantic the task - that feels like how magic items in the MoR Potterverse ought to behave.
For what it's worth, I believe Vaniver has the right answer.
- This thread has run its course. You will find newer threads in the discussion section.
Another discussion thread - the fourth - has reached the (arbitrary?) 500 comments threshold, so it's time for a new thread for Eliezer Yudkowsky's widely-praised Harry Potter fanfic.
Most of the paratext and fan-made resources are listed on Mr. LessWrong's author page. There is also AdeleneDawner's collection of most of the previously-published Author's Notes.
Older threads: one, two, three, four. By tag.
Newer threads are in the Discussion section, starting from Part 6.
Spoiler policy as suggested by Unnamed and approved by Eliezer, me, and at least three other upmodders:
It would also be quite sensible and welcome to continue the practice of declaring at the top of your post which chapters you are about to discuss, especially for newly-published ones, so that people who haven't yet seen them can stop reading in time.
