If you accept the hypothesis, wanded magic has the not-insignificant advantage of being more powerful. What's the advantage of wandless magic?
I thought it was obvious. What if you're without a wand?
Also, is that $25 million in 1991 dollars (year the book's taking place) or 2011?
There's got to be a spell for that, and it it likely to work similarly to the hover charm, i.e. instant effect.
Ah. Hundreds of girls Summoning a Harry Potter into their arms?
Maybe it's not that wands are needed to cast spells, but that they amplify magical power (and perhaps adds focus to a target). While the magically powerful are able to cast high level wandless magic, most are unable to. Hence, they have to use wands to make their spells powerful enough to have an effect. Children have spontaneous magic but they can't cast as much as adults normally can with wands.
Perhaps Roger Bacon just wasn't magically powerful. -shrugs- Not all great thinkers have to have tons of strength. Er, wasn't he Muggleborn? If the "Muggleborns-are-weaker" theory is true, then it makes sense.
My hypothesis for the reason why high-level wizards continue to use wands is that they've simply grown dependent. If they've been using magic-amplifying wands ever since they were eleven, then they would be used to being assisted by the wand. I think this matches my mental model of Quirrell, who is seen doing a lot of wandless magic (stopping spells midair, spontaneously combusting inkwells). He seems like the kind of person that would train himself to use his wand as little as possible. And even if he can't duel without, his magical ability is certainly very impressive.
A matter with the Comed-Tea that was bugging me for a while:
Chapter 14:
SO THAT'S HOW THE COMED-TEA WORKS! Of course! The spell doesn't force funny events to happen, it just makes you feel an impulse to drink right before funny things are going to happen anyway!
Hypotheses: Comed-Tea on person = impulse to drink, Comed-Tea not on person = no impulse to drink.
According to Chapter 12:
Harry couldn't help but feel the urge to drink another Comed-Tea. (And when he didn't...) Harry inhaled his own saliva and went into a coughing fit just as all eyes turned toward him.
So no matter what, even if you don't end up drinking it, you will get the Impulse before something funny happens.
Chapter 46:
I have been saving them for special occasions; there is a minor enchantment on them to ensure they are drunk at the right time. This is the last of my supply, but I do not think there will ever come a finer occasion.
So Harry has used up all of his Comed-Tea. (edit: it appears that Harry actually has tons left unless he's not mentioning some he drank/gave away, look at bottom of post)
...
WHY? WHYYY?!
It is apparent that you'll still get the impulse to drink whether or not you do end up drinking. So why didn't he save a can he's never ever going to drink?
Even if Harry will end up choking on his saliva, wouldn't the early notification of something ridiculous happening be helpful to him in any way? Like... it'd be an early warning to be prepared for whatever another person could say/do in conversation. Or if he's looking for interesting information, say from the library, he can just walk by all the shelves until he gets the Impulse-- that'd be an indicator that he's near the shelf that has the interesting book. There might be more uses.
Chapter 14:
Thankfully, Harry’s panicking brain remembered at this point that he did have something he’d been planning to discuss with Professor McGonagall. Something important and well worth her time. It was at this point that Harry realized he was faced with a priceless and possibly irreplaceable opportunity to offer Professor McGonagall a Comed-Tea and he couldn’t believe he was seriously thinking that and it would be fine the soda would vanish after a few seconds and he told that part of himself to shut up.
The charm even works for other people. If, for example, Harry wishes to test whether or not someone knows that Voldemort is alive, he could see if he has the Impulse to give that person a drink, all while thinking about saying that "The Dark Lord is still alive". If he gets the Impulse, they don't know. If he doesn't, then they already know/has been suspecting that he's been alive.
Chapter 8:
The boy reached into his pouch and said, "can of soda", retrieving a bright green cylinder. He held it out to her and said, "Can I offer you something to drink?"
Hermione politely accepted the soda. In fact she was feeling sort of thirsty by now.
In fact, just asking, "Are you feeling thirsty?" seems to be enough to trigger the charm's apparent spit-taking powers. Harry could think about talking about Voldemort, and ask if the other person's thirsty. If yes, they would take whatever he's going to say as a surprise, if no, then they won't. Geebus this thing is powerful.
edit: actually, I'm going to check the text and see Harry actually used up his supply. Be right back.
Chapter 7: “Two dozen cans please.” (24) He tossed a can to Draco and then started feeding his pouch... (23) (Harry's drinking one too) (22) Harry snarled, threw the can violently into a nearby garbage can, and talked back over to the vendor. “One copy of The Quibbler, please.” He paid over four more Knuts, retrieved another can of Comed-Tea from his pouch... (21)
Chapter 8: The boy reached into his pouch and said, “can of soda”, retrieving a bright green cylinder. He held it out to her and said, “Can I offer you something to drink?” (20)
Chapter 12: Harry reached into his pouch and whispered, “Comed-Tea”. (19)
Chapter 46: “Three sodas." (16)
Nevermind, Harry lied, he still has tons unless he's been drinking them and not mentioning it. However the Comed-Tea hasn't been mentioned since, so it might actually be all gone.
Draco's a manipulative little snake. Lucius never probably never asked, "Son, are you able to cast the Patronus Charm?" because he was probably under the impression that Slytherins weren't able to cast Patronuses so why bother asking. Hence, the topic never came up. Draco's a scientist now, he doesn't completely believe everything that Lucius says anymore. Draco's probably avoiding talking about dangerous subjects with his father. And of course, he could always lie.
I thought Draco promised Harry that Draco wouldn't tell Lucius about their interactions. Several times.
Five days was perfect in my perspective. To be honest I thought the speculation had the potential to be very fun and mentally stimulating but the way we did it was completely wrong. What ended up happening was everyone proposed own theories left and right and in the end only a few people got some of the answer right, whereas if we collaborated better we could have ended up with an entire community who guessed most of the answer right. Makes for more overall happy.
If we held off proposing solutions the first two days of analysis wouldn't get buried down in the first place. And to answer your question, forum posts can be edited, and the date posted is marked with an asterisk if it was. A wiki sounds sensible but it might be a little too complex for those who are unfamiliar with it, not to mention there'd be tons of editing conflicts going on. I propose Google Docs, for its real-time collaboration, or any other similar alternative. Etherpad?
In retrospect, our guesswork was a lot messier than it should have been.
Chapter 25:
One set of problem-solving groups had been given the instruction "Do not propose solutions until the problem has been discussed as thoroughly as possible without suggesting any."
The other set of problem-solving groups had been given no instructions. And those people had done the natural thing, and reacted to the presence of a problem by proposing solutions. And people had gotten attached to those solutions, and started fighting about them, and arguing about the relative importance of freedom versus efficiency and so on.
and
Starting out by looking for solutions was taking things entirely out of order. Like starting a meal with dessert, only bad.
While Less Wrong discussants are usually prone to less fighting and arguing than the norm, they are not prone to being inefficient.
What we should have done was forbade any and all solutions until two days after the chapter was released. We had five full days to guess, we didn't need to have all our solutions down the first twenty-four hours. Not to mention that instead of simpler solutions, we continued to look for answers more complex than the ones already proposed after we thought we already cleared the low-hanging fruit.
While some people have made an attempt to analyze first, listing everything in the room, things that only Harry knows, et cetera, the majority of us just proposed solutions right away. This was probably not what Mr. Yudkowsky wanted.
Word of God:
One thing I did notice was that many readers (a) neglected simple solutions in favor of complex ones, (b) neglected obvious solutions in favor of nonobvious ones, and (c) suggested that the correct hints had been put there for deliberately deceptive purposes.
...which in my mind I parsed as keep it simple, stupid, and you all were looking in the wrong direction and why the hell are you all proposing one preposterous idea after another, are you trying to look intelligent or something.
My only conclusion after reading that was that if we drew a map first we probably would of found the more probable solutions a lot quicker. Also reading through 1.5k+ comments full of solutions was headache-inducing.
Out of curiosity, does anyone know or have any idea what time the trial's taking place? If it's before 3 PM Harry's unable to use his Time Turner to change the events of the trial. Unless he cheats the Time Turner like last time, or gets his Time Turner's restriction taken off, but he can't do that easily while the trial is going on.
Harry had used up all six hours from his Time-Turner, and there were still no clues, and he had to go to sleep now if he wanted to be functional at Hermione's trial the next day.
"Wanted to be functional" meaning if he doesn't sleep now, he'd have little sleep. Which wouldn't have been a problem in the first place if he was allowed to sleep in.
"I think this has gone on quite long enough, wouldn't you say, Lord Malfoy? The boy will miss his classes."
...which means classes are still going on, at that moment (Monday). I'm not sure when classes end for Harry but it's probably closer to morning than evening.
Harry had read the Daily Prophet that morning.
Okay I have no clue now. But the wording implies that it's not morning anymore, so... I'm going with noon/early afternoon, 12 to 2 PMish.
Combining with this idea: Harry openly speaks about Patronus 2.0, everyone's Patronuses fail (especially the sparrow and squirrel currently guarding the Dementor, everyone would see them fail), Harry casts his Patronus to protect Hermione (or she figures it out and casts her own, not that she would get the chance to but she might figure it out at least), and the Dementor starts sucking souls until Lucius retracts his sentence.
Heck, maybe even threaten to spread Patronus 2.0 to the media, make wizarding Britain's animal Patronus population fail, then Aurors won't be able to keep their Patronuses up to guard Azkaban. So even if Hermione gets in, she wouldn't get her happiness sucked...
Thanks for the post, I'll definitely look at it after I'm done replying to this one.
When you say "privilege arguments for the positions you already hold", do you mean "only allow arguments that allow you a better chance of winning"?
This sounds like the wrong thing to say, but... I'll say it anyways, I want to see your reaction: what if you don't develop a tendency to fight the easier battle? What you say makes sense: losing less = learning less, until the point where you start to win/lose at a 50/50 rate at least. What if you pick arguments for the sake of arguing, or you promise yourself that you would only argue for the truth? Or, as is the case for me, what if you you have the tendency to fight for both sides (heck, this post)? I actually agree with you on all points, but for some reason I want to know how you would answer the opposing side, if I were on it.
Ah, I feel very embarrassed now. That was very ignorant of me-- to not consider the situations outside my own area. (stupid, stupid!) I can't believe I didn't think of that, especially the China thing, and only a couple of days after my mum told me how amazing the transportation in Taiwan was (to the point that no one really wants a car). Clearly I have much more to learn. (-facedesk-) The mistake won't happen again.
I've heard. Failing a case makes you feel worthless, and sometimes winning one makes you feel soulless. Maybe I should go into the milder forms of law. Patents, perhaps?
There you go! That's the one. :)
Very true, but very unhelpful answer. :/ If you don't use a car, how will you get to places?
Buses/taxies/motorcycles are probably one of the more convenient forms of transportation nowadays.
The only other thing I can think of are rapid transit, trains, bikes, and planes. But you can't ride the subway/bike/take a plane with as much flexibility as a car.
Salutations and whatnot! My name is Joyce, I'm a high school sophomore. Probably on the younger side of the age spectrum here, but I don't mind starting young. The idea of rationality isn't new to me, I've always been more inclined to the "truth", even when it sometimes hurts. In my mind knowing more about the truth = better person, so that's my motivation for being here. I'm have better grades than the average, but for the past couple of years the thing I hated most about myself was the fact that I usually "coast" a class, get my A, and then promptly forget everything I've done in the class. My goal was "get an A", not "learn something new". I'd like to learn new things now, and actually retain it, instead of just coasting by. Knowledge is power. I want to be the best, like no one ever was.
Um. When I was younger, perhaps ten, while I was tinkering with Photoshop, my older cousin approached to me and tried to introduce to me the idea of fallacies. He's...nine years older than me, so he was a barely an adult. I forgot most of the conversation, but from what I DO remember, blaming a stomachache on the last thing you ate was falling prey to SOME fallacy because it takes a day to digest food and thus you should think about what you ate 24 hours before, not two. (by the way I think this is wrong, your body reacts to bad food quicker than that, and can anyone tell me what fallacy this is? If it exists?) He also said if I wanted to win a lot of arguments I should learn about more fallacies. I was kind of doubtful and sort of didn't really care about the whole thing, but it must have been significant if the hard drive that is my brain hadn't completely forgot about it already.
What brought me here was Harry Potter and the Methods of Rationality, and what brought me to HPMoR was the writer Aspen in the Sunlight who wrote the Harry Potter fanfiction series A Year Like None Other (I didn't capitalize that correctly), and what brought me there was dragcave.net and from there I'm not quite sure. It was nearly three years ago, after all.
Ah, what else should I say. I'm an INTP. Psychology is the loveliest subject ever, oh it's just the most fun subject ever. I'm sort of taking AP Psych next year. And by that I mean buying the textbook off ebay or something and self-studying it along with my friend from another school who actually has the course, because my school doesn't offer the class. sigh Milgram's experiment was interesting and a little shocking, it's almost become my conversation starter ("Did you know that two-thirds of people would administer 450-volts of electricity through a person because a guy in a white lab coat told them to?"). Not sure what I want to be when I grow up, though I'm very well versed in computer technology. If not that, then law.
Someyears in my life I want to teach for a few years, just to experiment and find out what the best teaching method actually is. Traditional methods are so boring, and since a significant amount of my peers don't actually respond well to the current learning environment there obviously needs to be some updating to do. Electronics are going to be so cheap in the future, I could probably make my potential students shell out some 30 dollars for a decent tablet, install some heavily modded operating system, (Android/Apple if advanced enough by that time, Linux if not) lock it so my students can't tinker, and integrate that heavily in the curriculum. Sync my own tablet with all of theirs, kill some poor school's wi-fi. Maybe actually make a points system. Now that I typed that out it's losing its effectiveness appeal, but gosh, it'd at least be interesting.
