… 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.

I’m pretty sure this donut shop is in my town…

A new religious statue in the town of Davidson, N.C., is unlike anything you might see in church.

The statue depicts Jesus as a vagrant sleeping on a park bench. St. Alban’s Episcopal Church installed the homeless Jesus statue on its property in the middle of an upscale neighborhood filled with well-kept townhomes.

Jesus is huddled under a blanket with his face and hands obscured; only the crucifixion wounds on his uncovered feet give him away.

The reaction was immediate. Some loved it; some didn’t.

"One woman from the neighborhood actually called police the first time she drove by," says David Boraks, editor of "She thought it was an actual homeless person."

That’s right. Somebody called the cops on Jesus.

"ooh!  a poor person in need of help!  i better make sure they get arrested!"  to me, that’s the issue that’s most troubling.  Apart from that, the statue, and the idea behind it, is one of the parts of Christianity that even a grouchy atheist like me has to admire…
