Book: Harry Potter and the methods of rationality. Page 1

Quidditch teams will be recruited during the second week of the semester. Anyone wishing to play for their house team should contact Madame Hooch. Those who want, in principle, to change all the rules of the Quidditch game, should contact Harry Potter.

McGonagall, with her fingers whitened with tension, held on to the podium, guessing that the chaos spread everywhere by Harry had penetrated the Distributing Hat and now she would announce that for the needs of Harry Potter it was necessary to create a new Faculty of Evil Rock - or something like that - and, worst of all, Dumbledore would force her to organize it...

- I can't provide exact statistics. I don't know anything specifically, so I can't count anything. All I know is that I feel your chances aren't very good. I would even say very bad.
- But I'll never be like that! No way!
- I've heard this before.
- I'm not a potential Dark Lord!
- Exactly. Without a doubt.
- But why! Just because I once thought how cool it would be to have an army of blind fanatics chanting, "Glory to Dark Lord Harry!"
- It's funny, but that's not what you just thought about, quickly replacing the flashy thought with another, less dangerous one. No, you remembered how you wanted to build all the adherents of the idea of purity of blood and guillotine. Now you're telling yourself it was a joke, but it's not. If it were in your power, and if no one ever knew about it, you would do it right now.

I want to conduct experimental research on spells, define the laws behind them, make magic a field of scientific knowledge, merge the worlds of wizards and Muggles, improve the quality of life everywhere, move humanity forward for centuries, reveal the secret of immortality, colonize the solar system, explore the galaxy and, most important, to understand what the hell is going on here, because everything that happens around is absolutely unthinkable.

Note to the future: overthrow the government of wizarding Britain at the earliest opportunity.

I have no logical reason to be sure. My parents raised me as a boy named Harry Potter, and a lot of people said I was like my parents. In the sense of his other parents, Harry frowned, but I can't rule out that there are spells that give the child the desired appearance...

Thank you Mr. Potter. If you were already in any department, I would deduct so many points that even your grandchildren would continue to lose the School Cup.

There is no reason to be angry. Absolutely all parents are the same, adults never condescend to the level of a child, and his biological parents would not be an exception. Common sense is like a spark in the night, an extremely rare exception, an infinitesimal quantity in the overwhelming mass of madness, so it is pointless to be angry.

Muggle scientists have found that people are always overly optimistic: they say that some process will take two days, but in fact it takes ten, or they say - two months, and it takes more than thirty-five years. Or, for example, a survey of students was conducted, by what date they are 50%, 75% and 99% sure that they will complete their homework. And only 13%, 19% and 45% of them complete it by the specified time. Scientists have discovered the cause. The subjects were asked to describe the ideal and typical scenarios. And the resulting descriptions were almost identical. If you ask a person to plan something for the future, then he usually, imagining the most likely course of events, forgets about the possibility of mistakes or surprises. Most of the subjects did not finish the work by the deadline of which they were 99% sure, so that the actual results were worse than even the worst-case scenario. This phenomenon is called a "planning error," and the best way to avoid it is to consider how long it took to do any work in the past. That is, to look at the process from the outside. If you're taking on something for the first time and there's a possibility of failure, you have to be very, very, very pessimistic. So pessimistic that the results accurately exceed expectations. I, for one, work hard to present a grim picture of one of my classmates being bitten by a monster, but it could actually happen that the surviving Death Eaters attack the school to grab me. It's good that...
"Enough is enough," McGonagall interrupted.
Harry fell silent. He was just going to add that they at least knew that the Dark Lord wouldn't attack because he was dead.

- One of my classmates was bitten by a creepy monster, and I am in a mad rush to rummage in my wallet, trying to find something that can help her, she looks at me sadly and, taking her last breath, says: “Why were you not ready? " She is dying, and I understand that I will never be forgiven ...

For every Einstein in history, there have been thousands of equally intelligent people. But in order to achieve true greatness, they lacked one absolutely necessary thing, namely an important task.

Now I know you, Harry thought, waving his wand once, two, three and four, sliding his fingers to a precisely verified distance. I understood your nature. You symbolize death, according to some law of magic you are a shadow that death casts into the world.
And death is something I will never take.
It's just a childhood disease that the human race hasn't outgrown yet.
And one day...
We'll get over it...
And people will never have to say goodbye again...
He picked up the wand and pointed it precisely at the dementor.
- EXPECTO PATRONUM!

As thunder breaks out, your whole law becomes in vain. We will obey our husbands, and everything will be fine

If, in fact, commit the perfect crime, nobody will know about it. How then can you know exactly that there is no perfect crime?
If you look from this angle, it becomes clear that, perhaps, perfect crimes are committed constantly. The coroner announced that the death was from natural causes, the newspaper reported that the store never brought a substantial profit and finally closed down...
