… 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.

America’s First Cat Café Opens: Drink Coffee Alongside Adorable Cats
Yesterday, America’s first cat café opened in New York City. Cat lovers, you now have only three more day to sip coffee and eat pastries alongside adorable cats! Purina One teamed up with the North Shore Animal League, the country’s largest no-kill shelter, to create this pop-up café that’s the temporary home to rescue cats. While the concept of a cat café has been around for a while, with Asia and Europe leading the way, this is the first time one has opened in the United States. Two permanent cat cafés are scheduled to open in San Francisco this year.
The concept is simple. Visitors pay an hourly fee or cover charge to sit and lounge with cats. This one, on 168 Bowery, is free. Sixteen cats roam the premises and you’re welcome to pick one up and snuggle with it. If you fall in love with a particular one, you can even adopt it! (Read about each individual cat, here. Looks like “Sushi” is featured in the photo, above.) To get your feline fix, stop by the store from 10a to 7p each day till April 27. If you’d like to learn a little something, you can listen to different cat experts talk about cat health and behavior. The store’s capacity is limited to just 65 people, so you may have to wait in line.
