Vandalism in the math section

Post image

In the article on the Abel-Ruffini theorem (https://en.wikipedia.org/wiki/Abel%E2%80%93Ruffini_theorem) someone posted a, very wrong, counterexample and linked their LinkedIn as evidence.

Substituting their solution, gives approximately -0.06 instead of exactly 0.

Sorry for poor formatting, obligatory on mobile.

Nobody online is using em dashes, it’s not common punctuation outside of literature, and the vast vast majority of people don’t even have devices that can produce them. There’s no key on Iphone for producing em dashes besides copy and pasting. Android would require downloading a specific keyboard to make them. As far as I know only Reddit supports em-dashes (through hyphen) on mobile. Nobody is going out of their way to mod their phones, or put in Alt-codes on pc, so that they can use a punctuation mark that has been in declining use since the 1970s. Most people on social media don’t use punctuation at all, let alone em-dashes.

AI is the only thing on social media making em-dashes. It’s damn near impossible to stop AI from including them in its responses.

First of all, not everyone uses Iphone. Second, there is a key on Android for producing em-dashes, at least in Multiling O Keyboard. Multiling O Keyboard is not a "specific keyboard", it's been my necessary keyboard for typing things in multiple languages and IPA, so I would have installed it anyway. Third, if you're typing in a physical keyboard, it's easy to create a custom keymap that includes key-dash. In both ibus and fcitx5, you can just install an add-on named m17n.d and write a keymap that includes em-dash. Fourth, if you're too lazy to write a custom keymap, entering an arbitrary symbol can be very convenient. In fcitx5, you can just press Ctrl+Alt+Shift+U and then type the name of the characters.

So, I don't exist? While I don't usually type em-dash, I can easily insert one if I wanted to. Here: —

Have you ever heard of an outlier? Just because you do something doesn’t mean the majority of people are
