Thinking about the tragic idea of Charles having his powers from the womb, and sending his twin into a coma, injuring his mother and simultaneously himself. Charles' father recognizing what's happened and immediately experimenting on his son after Charles' is born. Charles growing up with voices in his head, crying and not understanding why no one was listening to him. Charles reacting telepathically in self defense and realizing that this isn't normal, possibly getting someone killed, thinking maybe he's a monster. His father dying unexpectedly but Charles feels nothing for him. Charles blocking his own horrific memories of experiments and frightening people at the young age of 5.

His mother starting to drink because Charles isn't enough, she misses her husband more than she loves her child. Sharon marrying Kurt, Charles knowing Kurt doesn't care about him or his mother. Cain coming to live with them, Charles possibly getting a brother in all this mess.

But Cain hates Charles, Cain is also being beaten by Kurt. Maybe Charles doesn't know he can stop Cain from beating him too. Maybe Charles thinks he deserves it. Then Cain and Kurt are arguing in Kurt's lab. Then there's a fire, and Kurt, surprising everyone saves Charles and Cain. Kurt knows, before he dies, that Charles is the one who saved them, Charles isn't the wiser till Kurt dies telling him to keep his telepathy a secret from Cain. Charles is 9 when Kurt dies.

The same year, Charles' mother continues to drink, and Cain continues to beat Charles, until America enters WWII, Kurt, older than Charles, is drafted into war, and never seen again. It's not until three years later that Charles finds out he's not alone. He never ever speaks about his "childhood" partially disgusted with himself for accidentally killing a man, and hoping Cain dies at war (which he also feels guilty about). His mother dies not long after Raven becomes his sister. Cain, Charles learns later, is presumably killed at war.

I'm only halfway though Hbomberguy's new video and I dont know if this is a universal experience but my main horrified takeaway from hbomb's plagiarism video so far is that one of my highschools TAUGHT AN ENTIRE CLASS OF 13 YEAR OLDS TO PLAGIARISE. LIKE, ON PURPOSE.

I ended up moving to a much better highschool, but my first highschool essentially taught us to "write" essays by reading what someone else had written and then write what they said again but putting it "into your own words". Which in practice was teaching us to change, for example, "the works of Shakespeare were regarded by many as the first popular art form" to "Shakespeare's plays have been said by some to be the first example of popular media". One teacher actually told us that the process of writing an essay was "saying what the people you've researched have said, in a way where it sounds like you said it".

Like. The tactics that actual plagiarists use to hide the fact that they were stealing. An actual teacher tried to teach me to do that.

MATH AT 8:04AM IS CRUEL

[dappersautismcreature]

yall im totally going down a rabbit hole (researching wayyy past what i need to for the 4maxhalo cowboy AU im planning) but qsmpblr... did yall know binary code has existed since like, the 1500's? not quite as a code, from what i can tell (help me im literally reading some musty old pdf from 1981) but for math, in fact there is speculation it may have existed earlier. (help me i am reading an old math website from 2006 that obviously hasnt graced a screen in over a decade -__-) basically i thiink it was is that in egypt they used a shorthand (instead of modern day calculators lmao) to multiply larger numbers, for example 60X70, by dividing one number by two a bunch of times and doubling the other number the same amount of times.

so binary in computers comes from halving, mathematical roots.

there is another instance of direct language to a sort of binary substitution cipher, but instead of 1's and 0's it is A's and B's and random instead of following a pattern. this was first seen in the 1600's.

then the modern day understanding of binary code to numbers started, in the 1920's and 30's with a number represented in 1's and 0's based on halving, like this:

^^ if you look at this chart you'll see that they halve 125, but instead of using decimals, they have a remainder, and that remainder decides whether it is a 1 or a 0. isnt that interesting? this was being created in the early days of computing when basic calculations took a lot of design and thought.

so calculators, when doing big multiplications and such, will go through a series of simpler dividing and multiplying in twos, based off of the binary code assigned to the inputted factors.

like these examples

so unfortunately this means that in the wild west (im going for 1870's-90's) they sadly would not know what binary code is :((

still,, isnt this fascinating?? O____O

*holding gun up* isnnt is-isnt this fascinating O____O?

today i walked through the park to the bus stop for my 8 am class and the leaves were green and red and yellow and orange, and there was mist hanging over the river and three swans gliding through the mist, and I didn't take any pictures because I didn't want to miss the bus so you'll have to take my word for it, but sometimes the world is actually just so beautiful
