Newtonian brooms are supported by canon then even more, aren't they?
Most Beaters are large and burly, and all the Seekers (with their premium on top speed) are the opposite. Exactly as expected with Newtonian brooms (or horses).
But if air resistance didn't matter because brooms move at a fixed velocity/acceleration in an Aristotelian manner, one would expect Seekers to have normally distributed body sizes as Quidditch team captains select for things like piercing eyesight, lightning reflexes, or just simian arms.
(Harry & Draco are both relatively small and thin; Viktor Krum is tall, but also 'thin'.)
Yes, that supports Newtonian broomsticks quite strongly.
- 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.
