Harry Potter and the Methods of Rationality discussion thread, part 28, chapter 99-101

palladias

This is a new thread to discuss Eliezer Yudkowsky’s Harry Potter and the Methods of Rationality and anything related to it. This thread is intended for discussing chapter 99, 100, and 101. The previous thread is at nearly 500 comments.

There is now a site dedicated to the story at hpmor.com, which is now the place to go to find the authors notes and all sorts of other goodies. AdeleneDawner has kept an archive of Author’s Notes. (This goes up to the notes for chapter 76, and is now not updating. The authors notes from chapter 77 onwards are on hpmor.com.)

The first 5 discussion threads are on the main page under the harry_potter tag. Threads 6 and on (including this one) are in the discussion section using its separate tag system.

Also: 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27

Spoiler Warning: this thread is full of spoilers. With few exceptions, spoilers for MOR and canon are fair game to post, without warning or rot13. More specifically:

You do not need to rot13 anything about HP:MoR or the original Harry Potter series unless you are posting insider information from Eliezer Yudkowsky which is not supposed to be publicly available (which includes public statements by Eliezer that have been retracted).

If there is evidence for X in MOR and/or canon then it’s fine to post about X without rot13, even if you also have heard privately from Eliezer that X is true. But you should not post that “Eliezer said X is true” unless you use rot13.

These are wizards. They can do, if not quite everything, a lot that we consider impossible or insanely hard. Maybe hydras have the magic property that they "stop time" nearby. For anyone near a hydra, time seems to freeze, at least until the hydra is dead. So if they can kill the hydra, the world pops back to normal with not a second past since the hyda attacked, but if not, they just get eaten.

This is a powerful attack/defense mechanism for the hydra, as the hydra's opponent must spend eon upon eon fighting it to win, and almost all give up before then.

At least, that is how I imagine Eliezer would write it if that kind of hydras appeared in canon and Eliezer had to come up with a reasonable explanation to it. Many things "don't make sense". How can dragons fly? They are to big to reasonably do so. But an intelligent author can "fix" things, and give a reasonable explanation.

Eliezer did that a lot to certain things from canon, and such is the correct attitude for facing a fictional thing you deem "impossible".

In that case, fighting hydras is something that any decently curious Wizard should attempt as a matter of course. Even if you're spending most of your effort watching the hydra, it still gives you a long time to think. No way (unless that's part of the hydra's spell) that you're coming out of that experience the same person!
