<h2>Historie</h2>
|
||||
<p>Psaní matematických vzorců na klávesnici nikdy nebylo jednoduché. Do vzniku Unicode většinou chyběly základní symboly jako × nabo √ a na jakékoli zápisy, které vyžadovaly zmenšování písma nebo vertikální umisťování textu, jako například zlomky či exponenty, byly zapotřebí různé podivné triky.</p>

<p>V <a href="grupy.html">minulém článku</a> jsme si vysvětlili, co jsou to <em>grupy</em>. Nyní se přesuneme do zdánlivě nesouvisející oblasti, kterou je teorie permutací, a následně si ukážeme, že tvoří jeden z nejzákladnějších druhů grup.</p>
|
||||
<h2>Základy permutací</h2>
|
||||
<p>Slovo <em>permutace</em> možná znáte ve významu přeházení pořadí nějakých věcí. A to není daleko od formální definice.</p>

<p>V <a href="http://mathsessions.klusik.cz/2021/01/03/latex/">minulém článku</a> jsme si vysvětlili, že \(\mathrm\LaTeX\)ový kód se skládá z příkazů a jak tyto příkazy vypadají. Ale jak vlastně začít psát takový \(\mathrm\LaTeX\)ový dokument? V zásadě existují tři možnosti:</p>
|
||||
<span id="more-2629" />
|
||||
<ul> <li>Obyčejný textový editor — např. <a href="https://www.vim.org/">Vim</a>, <a href="https://notepad-plus-plus.org/">Notepad++</a> nebo i Windows Poznámkový blok. Pozor, nikoliv editor formátovaného textu jako je Microsoft Word! O formátování se ostatně \(\mathrm\LaTeX\) postará sám. Napsaný kód se poté musí zkompilovat nějakým kompilátorem \(\mathrm\LaTeX\)u, nejpoužívanější je <a href="https://www.tug.org/texlive/">TeXLive</a>.</li> <li>Integrované prostředí, které poskytuje funkcionalitu pro editaci i kompilování zároveň. Příkladem je webová stránka <a href="https://www.overleaf.com/">Overleaf</a>, kde je možné bez jakéhokoli stahování napsat dokument a vytvořit z něj PDF.</li> <li>Nějaký jiný systém, který má podporu \(\mathrm\LaTeX\)ových vzorců. Tyto systémy podporují většinou pouze matematický režim. Patří mezi ně například WordPress, ve kterém je napsán tento článek.</li></ul>

It's played like regular tic-tac-toe, but instead of writing one mark, each player writes two small marks labeled with a unique number, which represent a mark in superposition. There may be multiple small marks in one space and whenever they create a cycle, the player who did not create the cycle can choose the way they will be collapsed — that is, write one regular mark for each pair of small marks in the cycle. If this destroys any other small marks, their counterpart will also turn into a regular mark, and this can chain. The rulas for winning are as usual — three regular marks in a row. It may even happen that both players win at once.</p><h2>Quantum chess</h2><p>When I played quantum tic-tac-toe with my friend, the idea really intrigued us and we wondered how the same concept could apply to a more complex game. And what better game to use for this purpose than chess? So we quickly decided on the rules, took out a chessboard and started playing. Unfortunately, we didn't finish the game, but here is a rough idea of the rules:</p><ul><li>In their turn, a player can choose between doing a quantum move and a collapse.</li><li>A <dfn>quantum move</dfn> consists of choosing two moves that could be played in regular chess and writing them down. This will create two possible positions. When there are already multiple positions, the player can make any two moves that are valid in <em>some</em> positions and they will be applied to all positions where they're legal.</li><li>With a <dfn>quantum collapse</dfn>, the player can choose a quantum move and discard one of the possible moves, which will also remove all possible positions resulting from this move and makes the other move the reality. If it turns out that some other move is now impossible, it will also be discarded, and this can chain.</li><li>A player wins when the opponent's king is captured in <em>all</em> possible positions. Note that the usual rules of check and checkmate would not get on well with quantum chess where a piece may or may not be somewhere, so all rules associated with check and checkmate (such and the king being unable to move through an endangered position when castling) are done away with.</li></ul><h2>Generalized quantum games</h2><p>We soon realized that these rules are not very precise and result in a lot of ambiguity. Therefore, we decided to formalize them. However, since the quantum part is pretty much separate from the rules of normal chess, why not define it in a way that can be used for all games? (Or at least for all deterministic turn-based games.) Therefore, we came up with the concept of game quantumification.</p><p>First, we need a formal idea of a game. I haven't really studied much game theory, so excuse me for using non-standard definitions and symbols.</p><ul><li>A <dfn>game</dfn> consists of a set of states \(S\) and moves \(M\) and is played by a sequence of players \(P\).</li><li>There is always a current state \(s_c \in S\) and a current player \(p_c \in P\).</li><li>A <dfn>move</dfn> \(m \in M\) is a partial function \(S \to S\).</li><li>There is a set of <dfn>available moves</dfn> \(M_a(s_c,p_c) \subseteq M\) that depends on the current state and player. The set may be empty.</li><li>The current player is allowed to choose one move \(m \in M_a\). The current state is then changed to \(m(s_c)\) and the current played is changed based on rules that depend on the game — usually to the cyclically next player in the sequence \(P\).</li><li>Some states are <dfn>final</dfn>.

h1 Susan and Male Privilege
|
||||
p.disclaimer This story is completely fictional. Take whatever you want from it.
|
||||
p “Men are so privileged.” Susan closed the browser tab with Huffington Post because the newest article criticizing the construction of a shelter for male domestic violence victims made her shake with rage. She put her phone into her pocket and continued walking through the marketplace. “I wish I could experience being a man. I would show them how to use the privilege correctly!” she muttered to herself.
|
||||
p “Then I have something exactly for you,” an old man sitting inside an aged wooden stall said slowly in a slightly unsettling voice. Susan turned to him with a disgusted expression and shouted: “Look at this <em>white male</em> with an opinion! Stop mansplaining!” The man, completely untouched by her hostility, slowly handed over an item from his stall. “This is the Monkey's Paw. It can grant you any wish you want.” Susan rolled her eyes. As a Sagittarius, she didn't believe in such superstitions. “I'm not giving any money to a man. You're already rich because of the wage gap, so you should be giving money to me.” “I don't need money,” said the man. “I'll happily let you use it for free. But be careful what you wish for, wishes always come with unexpected consequences.”

p Susan thought — what unexpected consequences could come with being a man? They have literally everything handed to them on a silver platter. “Fine, I'll try it. Monkey's Paw, I would like to become a man. And make it so that people forget that I used to be a woman.” The paw suddenly curled one of its fingers. Susan started feeling weird. Her waist got narrower. Her chest got wider, but the breasts disappeared and left only the nipples behind. She felt various parts of her body getting covered in hair. And her genitalia completely changed shape. She became… Sean.

p “Wow, it wor… AAAAAH!” he screamed as he realized that his voice had become rougher. “It's okay, I'll get used to this.” He threw another disgusted look at the stallkeeper — who was still a white male after all — and began walking home, excited to try out his newly acquired privilege. He decided that he's going to go through the shady neighborhood, where some random men would call him beautiful when he was a woman. Finally he doesn't have to worry about that!
|
||||
p “Hey, mate.” Sean was approached by a dirty and stinky guy in a black hoodie. “I ain't ate nothing today, would you spare some money for me?” Normally Sean wouldn't give him anything to avoid supporting his male privilege, but since now he was a man too, there was no power imbalance and he might as well do it. He took out his wallet and before he could think about how much money he's going to give, the beggar snatched the wallet out of his hands and ran away.

p “Phew, that was close. I need to get some money so this doesn't happen again.” He worked at BuzzFeed, so feeling inspired by the incident, he decided to write an article about how cisgender people are trash. He had already copy-pasted seven images from Twitter when he got a call from his boss. “Due to a new company policy to promote gender diversity and abolish the wage gap, we're not allowed to have any male employees. You're fired!” Before Sean could say anything, the boss hung up.
|
||||
p Sean thought about going to his partner and talking about it, but he realized he still doesn't have one. Well, what's a better time to go and find a girlfriend than now? He opened a dating app and started filling out his new profile. He decided that it would be a good idea to base his description on what kind of boyfriend he always wanted as a woman. “I'm a honest and caring feminist guy with a lot of interests. I love writing, music and adventures. I'm looking for a strong woman who can stand up for herself and treats me as inferior.” Perfect.
|
||||
p After swiping for two hours and not getting a single match, he figured that the app had probably been hacked and decided to try a more traditional form of dating. There was a nice bar close to his home, so he promptly headed there.
|
||||
p When Sean woke up, he found himself in a stinky room with thick iron bars on one side and gray walls on the remaining sides. “Oh, you're awake,” the prison ward muttered. “How in hell did I get here?” Sean asked. “Sexual assault,” the warden replied with an annoyed voice, lighting a cigarette. Sean started to vaguely recall the situation: after he had been rudely dismissed by several dozen women, he had finally found one that seemed interested in him, and after a bit of conversation, he pat her on the shoulder in a friendly way and she started yelling… Sean had to sit down and stop thinking because the cigarette smoke was making him nauseous.
|
||||
p After a few hours of utter boredom, he saw the door open and another warden walked in. “The lady has admitted that she had greatly exaggerated the situation. You're released. However, you're going to be permanently put on a sex offender list. Good luck finding a job now,” she reported and started maniacally laughing. After she had enough, she unlocked the cell.
|
||||
p Sean slowly walked home, not having any money for public transport. It was raining. He was beginning to think his male privilege was not working quite the way he imagined. But he really didn't want to give up. “What if I apply for a programming job?” he pondered. “Programming is a heavily male-dominated job full of misogynists and neckbeards, so they'll gladly accept me and won't care about some sex offender list.” He shuddered at the thought of working with so many incels, but this was the best plan he could come up with, so he decided to stick with it.
|
||||
p He looked at a board of programming job offers. Several of them offered free tutoring for beginners, but unfortunately, they were all availeble only for women. “It's fine,” he thoought, “they're going to accept me just for being male.” He proceeded to book an interview.
|
||||
p In the meantime, he got the idea that he could get some quick money on OnlyFans. He had great experience with it.
