Adrianne Haslet-Davis dances again for the first time since the Boston terrorist attack last year.
When the bombs went off at the Boston Marathon finish line, Adrianne Haslet-Davis lost the lower half of her left leg in the explosion. She’s a ballroom dance teacher, and she assumed she would never dance again. With most prosthetics, she wouldn’t.
But Hugh Herr, of the MIT Media Lab, wanted to find a way to help her. He created a bionic limb specifically for dancers, studying the way they move and adapting the limb to fit their motion. (He explains how he did it here.)
At TED2014, Adrianne danced for the first time since the attack, wearing the bionic limb that Hugh created for her.
Hugh says, “It was 3.5 seconds between the bomb blasts in the Boston terrorist attack. In 3.5 seconds, the criminals and cowards took Adrianne off the dance floor. In 200 days, we put her back. We will not be intimidated, brought down, diminished, conquered or stopped by acts of violence.”
Amen to that, Hugh.
… Y’see, now, y’see, I’m looking at this, thinking, squares fit together better than circles, so, say, if you wanted a box of donuts, a full box, you could probably fit more square donuts in than circle donuts if the circumference of the circle touched the each of the corners of the square donut.
So you might end up with more donuts.
But then I also think… Does the square or round donut have a greater donut volume? Is the number of donuts better than the entire donut mass as a whole?
A round donut with radius R1 occupies the same space as a square donut with side 2R1. If the center circle of a round donut has a radius R2 and the hole of a square donut has a side 2R2, then the area of a round donut is πR12 - πr22. The area of a square donut would be then 4R12 - 4R22. This doesn’t say much, but in general and throwing numbers, a full box of square donuts has more donut per donut than a full box of round donuts.
The interesting thing is knowing exactly how much more donut per donut we have. Assuming first a small center hole (R2 = R1/4) and replacing in the proper expressions, we have a 27,6% more donut in the square one (Round: 15πR12/16 ≃ 2,94R12, square: 15R12/4 = 3,75R12). Now, assuming a large center hole (R2 = 3R1/4) we have a 27,7% more donut in the square one (Round: 7πR12/16 ≃ 1,37R12, square: 7R12/4 = 1,75R12). This tells us that, approximately, we’ll have a 27% bigger donut if it’s square than if it’s round.
tl;dr: Square donuts have a 27% more donut per donut in the same space as a round one.
Thank you donut side of Tumblr.
There was a study done where they got a man to harass a woman in the park
and then they did it the other way around.
Several stopped the man but they let the woman slap and scream
and yank his hair.
They asked a professional who concluded that compared to men,
women aren’t seen as enough to be a threat.
My friend’s principal from three years ago
took his kids and ran
because he kept showing up to work
with bruises put there weekly by his loving wife
and everyone told him to take it like a man.
Last week I listened as a guy laughed off the idea
that a woman could violate him
and I thought of an interview on a news show
where they showed a boy who flinched inwards
every time a girl touched him
because of the exact reason the guy laughed off.
When compared to men,
Women aren’t seen as a threat
so men feel free to take whatever they like.
Women aren’t seen as a threat
so no one takes men seriously
when a woman
breaks them open.

Can I just say that it’s so nice to see something about women abusing men that doesn’t try to say feminism is the root of all evil, and in fact realizes the sexism against women is part of why this shit happens?
