On the 35th anniversary of The École Polytechnique massacre never forget the 14 women who were killed for being women in science

The École Polytechnique massacre (French: tuerie de l'École polytechnique), also known as the Montreal massacre, was an antifeminist mass shooting that occurred on December 6, 1989 at the École Polytechnique de Montréal in Montreal, Quebec. Fourteen women were murdered; another ten women and four men were injured.

Perpetrator Marc Lépine, armed with a legally obtained Ruger Mini-14 semi-automatic rifle and hunting knife, entered a mechanical engineering class at the École Polytechnique. He ordered the women to one side of the classroom, and instructed the men to leave. After claiming that he was "fighting feminism", he shot all nine women in the room, killing six. The shooter then moved through corridors, the cafeteria, and another classroom, specifically targeting women, for just under 20 minutes. He killed eight more women before ending his own life. In total, 14 women were killed, and 14 others were injured.

The massacre is now widely regarded as an anti-feminist attack and representative of wider societal violence against women; the anniversary of the massacre is commemorated as the National Day of Remembrance and Action on Violence Against Women. After the attack, Canadians debated various interpretations of the events, their significance, and the shooter's motives. Other interpretations emphasized the shooter's abuse as a child or suggested that the massacre was the isolated act of a madman, unrelated to larger social issues

The incident led to more stringent gun control laws in Canada, and increased action to end violence against women. It also resulted in changes in emergency services protocols to shootings, including immediate, active intervention by police. These changes were later credited with minimizing casualties during incidents in Montreal and elsewhere. The massacre remained the deadliest mass shooting in Canada until the 2020 Nova Scotia attacks over 30 years later.[4]

Timeline

Sometime after 4 p.m. on December 6, 1989, Marc Lépine arrived at the building housing the École Polytechnique, an engineering school affiliated with the Université de Montréal, armed with a Ruger Mini-14 rifle and a hunting knife.[5] He had purchased the gun less than a month earlier on November 21 in a Checkmate Sports store in Montreal. He had told the clerk that he was going to use it to hunt small game.[6] He had been in and around the École Polytechnique building at least seven times in the weeks leading up to December 6.[5]

The perpetrator first sat in the office of the registrar on the second floor for a while, where he was seen rummaging through a plastic bag. He did not speak to anyone, even when a staff member asked if she could help him.[2] He then left the office and was seen in other parts of the building before entering a second-floor mechanical engineering class of about sixty students at about 5:10 p.m.[7] After approaching the student giving a presentation, he asked everyone to stop everything and ordered the women and men to opposite sides of the classroom. No one moved at first, believing it to be a joke until he fired a shot into the ceiling.[8][9]

Lépine then separated the nine women from the approximately fifty men and ordered the men to leave.[10][9] He asked the women whether they knew why they were there; instead of replying, a student asked who he was. He answered that he was fighting feminism.[9][11] One of the students, Nathalie Provost, protested that they were women studying engineering, not feminists fighting against men or marching to prove that they were better. He responded by opening fire on the students from left to right, killing six—Hélène Colgan, Nathalie Croteau, Barbara Daigneault, Anne-Marie Lemay, Sonia Pelletier, and Annie St-Arneault—and wounding three others, including Provost.[9][11] Before leaving the room, he wrote the word "shit" twice on a student project.[10]

The gunman continued into the second-floor corridor and wounded three students before entering another room where he twice attempted to shoot a female student. When his weapon failed to fire, he entered the emergency staircase where he was seen reloading his gun. He returned to the room he had just left, but the students had locked the door; he failed to unlock it with three shots fired into the door. Moving along the corridor, he shot at others, wounding one, before moving towards the financial services office, where he shot and killed Maryse Laganière through the window of the door she had just locked.[12][11]

The perpetrator next went down to the first-floor cafeteria, in which about 100 people were gathered. He shot nursing student Barbara Maria Klucznick near the kitchens and wounded another student, and the crowd scattered. Entering an unlocked storage area at the end of the cafeteria, the gunman shot and killed Anne-Marie Edward and Geneviève Bergeron, who were hiding there. He told a male and female student to come out from under a table; they complied and were not shot.[13]: 30 [11]

The shooter then walked up an escalator to the third floor where he shot and wounded one female and two male students in the corridor. He entered another classroom and told the men to "get out", shooting and wounding Maryse Leclair, who was standing on the low platform at the front of the classroom, giving a presentation.[13]: 26–27  He fired on students in the front row and then killed Maud Haviernick and Michèle Richard who were trying to escape the room, while other students dived under their desks.[11][13]: 30–31  The killer moved towards some of the female students, wounding three of them and killing Annie Turcotte. He changed the magazine in his weapon and moved to the front of the class, shooting in all directions. At this point, the wounded Leclair asked for help; the gunman unsheathed his hunting knife and stabbed her three times, killing her. He took off his cap, wrapped his coat around his rifle, exclaimed, "Oh shit", and then killed himself with a shot to the head, 20 minutes after having begun his attack.[14][13]: 31–32  About 60 unfired cartridges remained in the boxes he carried with him.[14][13]: 26–27 

After briefing reporters outside, Montreal Police director of public relations Pierre Leclair entered the building and found his daughter Maryse's stabbed body.[15][16]

The Quebec and Montreal governments declared three days of mourning.[15] A joint funeral for nine of the women was held at Notre-Dame Basilica on December 11, 1989, and was attended by Governor General Jeanne Sauvé, Prime Minister Brian Mulroney, Quebec premier Robert Bourassa, and Montreal mayor Jean Doré, along with thousands of other mourners.

dottore having to dispose of a faulty clone (maybe bc they were threatening reader) and then handfeeding reader parts of it like cannibalism as a metaphor for love…. do we see the vision or is this a little too 𝓯𝓻𝓮𝓪𝓴𝔂 💔💔

A/n: pookie you're all good, thank you for feeding my brain worms with this idea I'm sending you smooches. I do hope I executed this well. I had a lot in my head that I wanted to write for this but I didn't want this to turn into a word scramble so here's this. Enjoy <3

Content: Dottore x GN reader, dark content(?), a bit yandere, implied unhealthy relationship, implied cannibalism, cannibalism as a metaphor for love, idk what else to tag as I never posted something like this so if anything else needs tagging feel free to lemme know

Words: 735

Several candles lined the polished oak table, its surface smooth and almost sticky, the light rippling over the dark lines of the carvings on top like little light bugs chasing one another. The golden hues danced over the plates as well, but the dim light scarcely allowed for a good look at the dishes.

The fork extending forward to your lips was the only thing that held your attention long enough to be observed, taken in fully, lips closing around the bit of meat and vegetables. The juice and oil fills your mouth, sinking past your teeth and around your gums, the taste is rich yet stale all at once. You couldn’t comment on it, you didn't know what to say about it. Not with the Doctor sitting at your side and being the one to feed you so, so gently.

It's hard to remember when was the last time he looked so gentle, kind even, perhaps when he was lighting up the candles with such care, as if his own breath would blow the flames into a blaze, allowing you to see your plate in full.

The meat was well done, seasoned to your liking, and something told you it was Dottore’s own hand who prepared it, gave it his all to make it so perfect for consumption. Parts of him were laced through every sensation, every smell and every bite. Your own plate is set before him and he's cutting all your bites, spearing pieces of meat and salad onto the fork before feeding it to you, making sure you ate well.

The dull ache in your arms is brought back into memory as you languidly chew on a bite, and your fingers absentmindedly touch over your sleeves over where the bruises lay, feeling the ache grow.

“Do they still hurt you?” His voice called out amidst smoky smells and brown fog, calling you to the present. “Have you gotten any rest at all, my dear?” He added, his head tilting in your direction, his bird-like mask not allowing you for a glimpse of his ruby eyes, but from underneath you can see glimpses of the scars peeking through, teasing your eyes. For some reason he chose to wear it here, now, only puzzling you further. 

“No.. no.. they're fine… I’ll get some rest later tonight, sir..” you reply as you swallow and watch how he grimaced at the title, and you nearly cough from how big this bite was, but you would have taken a bigger bite had Dottore allowed you to feast yourself. Perhaps not, but you told yourself you would. Be it the rich taste or some other factor, you yearned to take up each bone from the meat and lick it clean, sucking out the marrow from within and letting it melt into your guts.

Would he be satisfied then?

Would you be?

The candles flicker. He's still looking at you

“Are you still afraid? I've already told you so, and explained it many times. You have nothing to fear here. This was just an error in the system which will not ever happen again.. and you shouldn't have been around to witness it, anyhow..”. You have to wonder how he can say all this with so little fear. Then again, the clone was his creation. He knew it inside and out, every crevice and every wire.

“I understand.. it's just that.. I'd rather not face the others now..not after that..” 

Truth be told, having him around was also slightly unnerving, as he wore nearly an identical face as the one that harmed you. They were the same, but also not. He was gentle, but he was not.

The one that hurt you was long disposed of and would never harm you again, but Dottore was once the one that hurt you, and now he has poured himself out before you, all for your pleasure and the sweet poison of safety and love.

He hopes to convey it to you through each meticulously put bite, every sip he graces your lips with. He had cut himself open for you and would do so again, just as he hurt you through that error. It came as easy as drinking and breathing. 

“That’s understandable. I assure you are safe, and however dark the night may get - I'll be there with you… But for now, you must eat, not fear. Open wide..”

One week left until my ochem final. Oscillating between "it's fine, I got this, most of the material is in my head already" and "AAAAHHHHH" as is the case every exam sesh. Reading a textbook on group theory for chemists for fun (and to make my thesis supervisor proud bc academic validation am I right :'))))

Orm looms over her shoulder. "The gods took your weapons and gave you children."

She goes as rigid as the resting city.

Orm's clover-shaped face folds with a clatter, shuttering; the warforged is laughing. "I steal the words from Maes. Credit your surprise to them, not I."

"You are not children," Valka answers eventually. "When the warforged woke, they - you - understood violence. You understood that you were being used."

"Did we?" Orm asks. "Would children?"

some less polished warforged, D6 and Orm. these guys weren't gonna come up for a long while, in a self-governing, physically walking warforged settlement named Wanderstrand - a lifestyle only possible, with the destruction after the war, when your main population doesn't require any food or water from the land it visits.

there’s a post floating around here claiming that sokka is the only person keeping the atla kids alive and it very much reminded me of how the labor that women perform is often undervalued and overlooked. (and this post is not meant to be targeted towards op at all, but rather is speaking towards a general trend that i’ve noticed in the atla fandom)

i recently rewatched atla and it’s surprised me that the fandom interpretation is that only sokka is worried about the group’s lack of food/money, particularly in book 1, because katara worries over the exact same things and is usually the one backing up sokka. in “the warriors of kyoshi,” sokka reminds aang that they need to make it to the northern water tribe soon and stop making pitstops, and katara agrees with him. when they stop at kyoshi island, katara reminds aang multiple times that it’s risky to stay in one place for too long. in “the waterbending scroll,” sokka worries over how little money they have left after aang wastes money on a bison whistle, so katara takes charge of keeping track of the money instead, and she also reminds aang that they need to practice waterbending, not focus on having fun. in “the storm,” katara realizes they’re out of food and says they need to go to the market, then sokka gets a job so they’ll have more money for food. in “the king of omashu” and “the deserter,” sokka worries that aang will be discovered, and katara agrees so she suggests that they wear disguises. in “the cave of two lovers,” sokka says they need to focus on getting to omashu without getting sidetracked, and katara agrees. in “avatar day,” sokka and katara buy food/supplies together while aang waits for them. 

despite sokka being seen as the pragmatic sibling, both katara and sokka are pretty united in their practicality and trying to keep their mission on track. katara only makes exceptions on a couple occasions when she values standing up against injustice even more than sticking to the plan, such as freeing the imprisoned earthbenders or helping the fire nation village as the painted lady. and the way that i've seen people use katara’s passion for social justice as a way to argue that she’s “irresponsible” seems a bit disingenuous considering that she sees it as a moral duty to help people in need (and let alone everything else she does on the day-to-day to help the group).

(“the library” is in fact the only episode in the entire show that i can remember where katara disagrees with sokka and says there’s no harm in having some fun in their downtime. and as soon as sokka finds out about the existence of the library he’s also fine with taking a break from their mission lol. despite what the fandom thinks, it’s not the norm).

and while there’s a lot of focus on sokka’s mapping/planning skills, there’s also so much that katara does so much behind the scenes that isn’t as explicitly acknowledged. “the chase” tells us that katara, aang, and sokka all contribute pretty equally to setting up their camp while traveling. in “jet” they all help pack up camp, in “the great divide” sokka sets up their tent, katara collects firewood, and aang gathers food. and yet even though they all seem to contribute pretty equally to setting up camp, we are shown so many scenes of katara doing extra chores while the others are preoccupied with something else. in “the southern air temple,” katara packs up their supplies while sokka is sleeping, then again packs up everything while sokka’s eating the food momo gave him. “the warriors of kyoshi” episode implies katara is the only one mending everyone’s clothes, and while sokka is getting his ass kicked training with the kyoshi warriors and aang is entertaining his fan girls, katara is shopping for food and supplies.

in “the painted lady,” the group all goes shopping for food together, but it’s katara who cooks dinner for everyone (shown twice in this episode). in “the runaway,” katara’s at camp cooking for everyone while they’re off tricking a gambler to make more money. sokka, aang, and toph buy food/supplies, then leave them with katara to sort out while they go have fun in the village (and sokka gets to buy his messenger hawk). and katara’s the one seen as a “buzzkill” for worrying about their safety. this pattern continues in “the western air temple” and “the firebending masters” where we see katara cooking and serving food to the group, but there aren’t scenes of them doing other chores.

and of course, “the desert” is an entire episode dedicated to katara keeping the group alive. and that’s not even to mention the countless amount of emotional support that she gives to her friends, often putting other people’s needs above her own. sure, katara might not be the person with the map or the master plan, but that doesn’t mean her contributions are any less important.

sokka’s character arc involves growing into a strong leader and strategist, so it makes sense that the fandom often likes to focus on the moments that go into building this arc, the moments where he does take the lead and is responsible. but for katara? it’s just something required of her and of most female characters. taking on extra responsibilities is something to be admired in men, but just expected of women. 

and to be clear, i’m not saying that sokka is not responsible, he definitely is. i just find it interesting that some parts of this fandom have a skewed perception of katara’s role in the group, often claiming her to be the “irresponsible” or “immature” sibling while poor, exhausted Dad!Sokka™ is the only one keeping these silly kids alive. sokka and katara both had to grow up too fast, they’re both kids who are very mature for their age and took on adult responsibilities far too young (though in different ways). acknowledging the sacrifices katara made and the labor she took on to take care of others isn’t diminishing sokka’s character arc, it’s something he even admits in the show himself. and i love their relationship because even with such a complicated family dynamic, it’s so clear how much they love and support each other.

Creep

Also known sometimes as cold flow, creep is the slow plastic, or permanent, deformation of solid materials that occurs over time when said materials are subjected to constant stress. Creep is most significant in solid materials that are operated at high temperatures, such as jet engine turbines, as the rate to failure is typically faster the higher the temperature. Several internal mechanisms contribute to creep, dependent on materials' microstructures, properties, composition, etc., including dislocation movement, grain boundary sliding, and diffusion. Creep is not just limited to polycrystalline metallic solids; plastic, wood, concrete, and glass materials, among others, also experience creep.

I forgot to post this yesterday 'cause I got home so late from uni 😭

Yesterday was a pretty tiring, but worth it, day of studying since I missed an entire week of class and had to study all of the content from last week's welding technology class + study from a texbook on science and engineering of materials.

Content studied yesterday:

> Stress-Strain of metals under tension, compression, sheer and torsion tests ;

> Stress-Strain graph (elastic and plastic strain, recognition of ductile and brittle materials, points of elastic limit, yielding, ultimate strength and rupture) ;

> General types of welding ;

> Concepts of welding technology .

My welding technology class went great and I was relieved when I found myself following the explanations with ease and being able to participate because of successful studying and absorption of the last class' content through photos of the board that my classmate sent me. I was really scared I would fall behind but I feel pretty confident and intrigued by the subject and engineering in general... I think I'm finally falling in love with it!

Finding new ways to slow fleeting waves of light or even stop them in their tracks could lead to more advanced photonic devices, such as lasers, LED displays, fiber-optics, and sensors. In a cunning trap made from a silicon crystal tweaked to behave as if it's deformed, scientists have found a flexible new way to make light waves stand absolutely still.
