Donuts are generally round with a hole in the middle unless they’re filled, but have you ever stopped to consider whether or not the hole is optimally sized? Mathematician Dr. Eugenia Cheng did, so she used calculus to figure out the right size for the hole. She first determined that a bigger hole increases the surface area creating a crisper donut.

She then went on to measure the “squidginess” and “crispiness” ratios of the donut to determine that a ratio of 3.5:1 which comes along with an 11 mm hole makes for perfection. Of course, your tastes may vary but I’ll buy into any science that uses a term like “squidginess” to prove its point.

So, why does a big slice of pizza tend to droop unless you fold it into a curve? Well, there’s some math involved in all this pizza folding: the basic concept here deals with the 19th century principle of Gaussian curvature.

Wired’s Aatish Bhatia used the pizza question as a nice starting point to explain this unique aspect of geometry, and once you understand this principle, you’ll never look at pizza the same way again.

Well, it’ll still look delicious of course, but you get my point.

The Chocolate Mill is the brainchild of chocolatier Rafael Mutter, Dutch architect and furniture designer Gerrit Rietveld, and Studio Wieki Somers. 10 layers of cocoa-based confection were filled with flavored patterns, then shaved away incrementally with a crank-turned blade. It’s a display of food and artful science that can be appreciated by all.

A video of the Chocolate Mill in operation can be found after the break.

If you’re like me, you probably cut your cake into slices of all sizes–the people I like get the big pieces, and the grumpy party-poopers get the tiny slivers. It’s only fair.

Anyway, there’s actually a proper, more scientific way to serve up cake. In this YouTube video by Numberphile, mathematician Alex Bellos shows us how to cut up a cake into proportional pieces that keep leftovers fresh.

So, yes, thanks to science, even the party-poopers get a decent slice. You’re welcome.

Vi Hart, a quirky mathematician with a knack for doodling and a love for making entertaining vlogs, recently released a new video where she makes extremely precise, geometrically shaped cookies with her friends. Oh, and her friends, Andrea Hawksley and Gwen Fisher, happen to be math fanatics too. Vi Hart’s sister, Ruth of Sweets by Ruth, who’s also a hardcore baker, is along for the ride. Together the mathematically inclined ladies make some cool 3D cookies using icing and brain power.

Slicing and dicing your veggies to prep for dinner is a boring task, but it’ll be a lot more fun with one of these cutting boards. Each is laser-etched with wonderfully nerdy stuff like pi, quotes from Marie Curie and Einstein and even the whole solar system.

Oreos. The stuff that noms are made of. But how much Stuf is in the stuff Oreos are made with?

This is what Dan Anderson asked the students in his “Consumer Math” high school course. He asked them to determine whether the Oreo Cookies were, indeed, double and mega stuffed.

It seems the math might not add up the way Oreo may have hoped. Anderson said his class “weighed 10 of each – Double Stuf, Mega Stuf and regular, and we weighed five wafers alone to deduct from the total.”

What they found was that the Double Stuf Oreos were 1.86 times bigger and the Mega Oreos were 2.68 times bigger, according to the calculations. A spokeswoman for Nabisco reacted to the news thusly:

“While I’m not familiar with what was done in the classroom setting, I can confirm for you that our recipe for the Oreo Double Stuf Cookie has double the Stuf, or creme filling, when compared with our base, or original Oreo cookie,” the spokeswoman said.

Granted, they may have left cream on the wafer and maybe someone dipped their finger in the Stuf. Or maybe Nabisco is ripping us all off.

Maybe this is a job for the Mythbusters.

For most of us, a bagel is an on the go breakfast that exists solely to satisfy hunger. However, for George Hart, the bagel is a mathematical problem that must be solved so it can become a perfect example of interlocking deliciousness.

If you really care, you can check out the overly complicated method in the video after the jump.

We think it’s pretty safe to say that Nathan Shields makes some of the nerdiest pancakes on the planet—but few are nerdier than this series depicting mathematical constants.
