Heart attacks symptoms are different for women. I recently learned this.

OKAY THIS ARTICLE IS SO COOL

I'm going to try to explain this in a comprehensible way, because honestly it's wild to wrap your head around even for me, who has a degree in chemistry. But bear with me.

Okay, so. Solids, right? They are rigid enough to hold their shape, but aside from that they are quite variable. Some solids are hard, others are soft, some are brittle or rubbery or malleable. So what determines these qualities? And what creates the rigid structure that makes a solid a solid? Most people would tell you that it depends on the atoms that make up the solid, and the bonds between those atoms. Rubber is flexible because of the polymers it's made of, steel is strong because of the metallic bonds between its atoms. And this applies to all solids. Or so everybody thought.

A paper published in the journal Nature has discovered that biological materials such as wood, fungi, cotton, hair, and anything else that can respond to the humidity in the environment may be composed of a new class of matter dubbed "hydration solids". That's because the rigidity and solidness of the materials doesn't actually come from the atoms and bonds, but from the water molecules hanging out in between.

So basically, try to imagine a hydration solid as a bunch of balloons taped together to form a giant cube, with the actual balloon part representing the atoms and bonds of the material, and the air filling the balloons as the water in the pores of the solid. What makes this "solid" cube shaped? It's not because of the rubber at all, but the air inside. If you took out all the air from inside the balloons, the structure wouldn't be able to hold its shape.

Ozger Sahin, one of the paper's authors, said

"When we take a walk in the woods, we think of the trees and plants around us as typical solids. This research shows that we should really think of those trees and plants as towers of water holding sugars and proteins in place. It's really water's world."

And the great thing about this discovery (and one of the reasons to support its validity) is that thinking about hydration solids this way makes the math so so so much easier. Before this, if you wanted to calculate how water interacts with organic matter, you would need advanced computer simulations. Now, there are simple equations that you can do in your head. Being able to calculate a material's properties using basic physics principles is a really big deal, because so far we have only been able to do that with gasses (PV=nRT anyone?). Expanding that to a group that encompasses 50-90% of the biological world around us is huge.

story time

In 7th grade, I knew this boy that was SO RACIST I genuinely couldn't bring myself to believe he was serious at first. I was still friends with him and the thing was, even though he was a absolute cardboard tube he would give the utmost respect to your sexuality like tht was WAY out of left field (;). I was a pan/bi Indian girl and he would make so many jokes about me being Indian but he would respect the hell out of my bisexuality. It helped my imposter syndrome so much man, he never said shit like, "When are you gonna pick???" Or anything, and he would occasionally tell me what his favorite Indian food was and I think he actually stopped being racist but I'm not sure. being his friend blew my mind at how many different types of belief systems there were his parents were like racist and homophobic so I don't what happened for him to specifically not be against gays but his best friend was a lesbian he had a close ace friend all while he was straight as a line and white as Elmer's glue. Don't know what was up with him but he had a surprising amount of POC as friends too idek anymore man this world is cray cray

PICK SOMETHING MY MAN WTH 🤦‍♀️ #The day humans are consistent is the day the sun swallows the earth then we'll all be consistently dead #One time he got mono and just would not shut up about it #Of course this happened in America what'd u expect???

I've been resource gathering for YEARS so now I am going to share my dragons hoard

Floorplanner. Design and furnish a house for you to use for having a consistent background in your comic or anything! Free, you need an account, easy to use, and you can save multiple houses.

Comparing Heights. Input the heights of characters to see what the different is between them. Great for keeping consistency. Free.

Magma. Draw online with friends in real time. Great for practice or hanging out. Free, paid plan available, account preferred.

Smithsonian Open Access. Loads of free images. Free.

SketchDaily. Lots of pose references, massive library, is set on a timer so you can practice quick figure drawing. Free.

SculptGL. A sculpting tool which I am yet to master, but you should be able to make whatever 3d object you like with it. free.

Pexels. Free stock images. And the search engine is actually pretty good at pulling up what you want.

Figurosity. Great pose references, diverse body types, lots of "how to draw" videos directly on the site, the models are 3d and you can rotate the angle, but you can't make custom poses or edit body proportions. Free, account option, paid plans available.

Line of Action. More drawing references, this one also has a focus on expressions, hands/feet, animals, landscapes. Free.

Animal Photo. You pose a 3d skull model and select an animal species, and they give you a bunch of photo references for that animal at that angle. Super handy. Free.

Height Weight Chart. You ever see an OC listed as having a certain weight but then they look Wildly different than the number suggests? Well here's a site to avoid that! It shows real people at different weights and heights to give you a better idea of what these abstract numbers all look like. Free to use.

story from middle school

in middle school I used to play 4 square on Fridays with a few 7th graders. among these 7th graders was a boy named Ian. Now I don't know what his problem was but every once in a while, the ball was thrown out of the square, he would hit it back in, when he wasnt in the game. Meaning, we had to restart due to interference of an outside party. Eventually this happened so often that we started calling it ianference instead. Anyway, the ball bounced. hit him in the face before he could hit it, he had a nose bleed and went to the nurse. The end.

#I don't know how to tag #I did like hanging with him though #He wasnt as bad as jason #Funk Jason all my homes hate jason #Academic anecdotes #School stories #BTW I don't remember if ian actually got hit or not #He had like semi regular nose bleeds #The PE teacher had to wipe blood off the floor before we could play again. #This was indoor 4 square #Sooo... yeah.

About sexuality

if there is no difference between genders other than how stereotypes of the gender effect their upbringing then why would anyone have a preference for a certain gender? A man can have a vagina a woman can have testicle that should be one of the biggest physical differences and they are not exclusive to either gender what is the preference for???

like I get asexual and romantic people I'm asexual myself but for allosexuals and alloromantics what separates one person who can be romantic from another? It feel arbitrary.

Difference between male & female

Is there a big difference between male and female bodies?

Like besides obvious ones like reproductive organs. Are the skeletons very different?
