… 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.
This is the highest and best use of conic sections I have ever seen.
Did you know that you can make houses out of plastic bottles? By filling them with sand, and molding them together with mud or cement, the walls created are actually bullet proof, fire proof, and will maintain an comfortable indoor temperature of 64 degrees in the summer time.
And it’s not like there is any shortage on used plastic bottles out there. Here are some statistics from treehugger.com:
“The United States uses 129.6 Million plastic bottles per day which is 47.3 Billion plastic bottles per year. About 80% of those plastic bottles end up in a landfill!”
To build a two bedroom, 1200 square foot home, it takes about 14,000 bottles.
The United States throws away enough plastic bottles to build 9257 of these 2 bedroom houses per day! That’s just over 3.35 million homes, the same number of homeless people in America.
Many people in third world countries have taken up building homes out of plastic bottles, from Africa to Asia. Perhaps the trend will catch on in America and all of those bottles will stop ending up in the landfills. Wouldn’t they be better off housing the homeless? Kinda like all those empty houses scattered all over the country?
on my grave i want VIP not RIP
you better pop lock and drop that attitude
houston i have so many problems
my entire experience in high school
I BET THAT IF TWO KIDS LIVED IN THOSE TWO HOUSES THAT THEY WOULD COME OUT ON THEIR ALMOST CONJOINING ROOFS OUTSIDE THEIR BEDROOM WINDOWS AND TALK AND BE BEST FRIENDS AND FALL IN LOVE.
I will not write fluff to that. I won’t. No.
LUCY I FOUND IT
But what if instead of two kids, it was, say, a kid and an old woman? And at first they just ignore each other and keep their blinds down and curtains shut, but then the kid climbs out onto the roof one spring morning to get a frisbee and she’s got the window open bc it’s so nice out and she tells him to cut that out, it’s not a jungle gym and maybe the kid shows off a bit and nearly falls, and the old woman catches his arm…. anyway, so sometimes they leave the windows open and the kid’ll show off his comic books or asks what rhymes with ‘beautiful’ (and it’s totally for homework shut up), and the old woman tells him about all the protests and marches she took part in, and asks him the name of that one cute pop star (it’s absolutely for her crossword now shush). And the old woman gives the kid relationship advice and doesn’t tell when he tries a bit too much of his parents’ liquor cabinet one time, and the kid comes over and shows her how to use the smartphone her daughter bought for her and doesn’t tell when she sneaks a cigarette out of said daughter’s bag. And when the weather’s too bad to open the windows, they tape silly pictures or notes to the glass for the other to see (the kid makes sure to make his extra big so she doesn’t have to admit her eyeight isn’t what it used to be), and when it is nice the kid will sneak over and leave seashells on her windowsill, because the old woman said once she misses the sea, but she can’t travel like she used to. And one day he peeks in her window and sees her on the floor, and calls 911 and basically saves her life because she had a stroke and nobody would’ve known in time otherwise. And when she finally gets back from the hospital, just for a while because her daughter’s talking about a retirement home where she’ll have plenty of medical care and lots of friends her age, the kid comes through the window and then pulls another kid through the window who he introduces as his boyfriend, and says he wanted her to meet him. And she sniffs and interrogates the boyfriend in proper elderly relative fashion, and then declares him worthy of her boy— barely. And when she finally does have to go to that retirement home, the kid still comes to visit her, and always leaves seashells on the windowsill.
I’m not crying or anything
I am omg
