did you know soap doesn’t really clean your hands it just makes the water molecules smaller so the water can go into smaller crevices in your skin isn’t that the weirdest shit you’ve read today

Not true. Water molecules are of a fixed size.

Soap cleans your hands by making things that don’t normally dissolve (like oils) able to dissolve

Molecules have a property known as polarity, and basically, polar stuff dissolves in polar stuff. Non-polar stuff dissolves in non-polar stuff but non-polar and polar won’t mix because polar molecules are snobs who gather together and ignore non-polar molecules. Water is very polar, oils and fats are largely non-polar. This is why they separate into layers.

Soaps and detergents, on the other hand, have one polar end and one non=polar end. Water totally wants to hang with half of a soap molecule, but the other half needs to get out of the damn way to make more room for polar molecules. So soap molecules hide their unwanted non-polar ends in non-polar stuff lik other non-polar soap ends, air (this is how bubbles form, by the way; they’re fluid-coated soap molecules trying to keep their non-polar halves out of water’s way), and things like oil, dirt and grease while their polar ends are out high-fiving water molecules and having a grand old time. This causes little soap-coated particles of dirt or oil to break away and effectively dissolves them, like in this diagram:

Oh, and as a side note? Soaps aren’t the most prevalent things to do this. Phospholipids that make up the outside of our cells also have polar and non-polar ends and arrange themselves like this:

You’re literally made of bubbles is what I’m trying to say here.

Several studies have shown that portrayals of women enjoying rape and other kinds of sexual violence can lead to increased acceptance of rape myths in both males and females.

One group of college students were shown a pornographic depiction in which a woman was portrayed as sexually aroused by sexual violence, and a second group was exposed to control materials.

Subsequently, all subjects were shown a second rape portrayal.

The students who had been exposed to the pornographic depiction of rape were significantly more likely than the students in the control group:

(1) to perceive the second rape victim as suffering less trauma; (2) to believe that she actually enjoyed it; and (3) to believe that women in general enjoy rape and forced sexual acts.

Columbia student will carry her mattress until her rapist exits school
September 2, 2014

While most students at Columbia University will spend the first day of classes carrying backpacks and books, Emma Sulkowicz will start her semester on Tuesday with a far heavier burden. The senior plans on carrying an extra-long, twin-size mattress across the quad and through each New York City building – to every class, every day – until the man she says raped her moves off campus.

“I was raped in my own bed,” Sulkowicz told me the other day, as she was gearing up to head back to school in this, the year American colleges are finally, supposedly, ready to do something about sexual assault. “I could have taken my pillow, but I want people to see how it weighs down a person to be ignored by the school administration and harassed by police.”

Sulkowicz is one of three women who made complaints to Columbia against the same fellow senior, who was found “not responsible” in all three cases. She also filed a police report, but Sulkowicz was treated abysmally – by the cops, and by a Columbia disciplinary panel so uneducated about the scourge of campus violence that one panelist asked how it was possible to be anally raped without lubrication.

So Sulkowicz joined a federal complaint in April over Columbia’s mishandling of sexual misconduct cases, and she will will hoist that mattress on her shoulders as part savvy activism, part performance art. “The administration can end the piece, by expelling him,” she says, “or he can, by leaving campus.”

As painful as I know the constant reminder of attending school with her rapist must be, I’m glad she won’t be the only one forced to remember. I hope the rapist drops out immediately…or better yet, I hope he faces the justice he deserves. 

this is what a hero looks like

Enough with the love songs. I need cheesy pop songs about protein signaling pathways and med school concepts so I might actually remember them.

I’m… confused.
