Redditor Joshua_Glock crowdsourced help when he spotted this sign at Yaya’s Thai Restaurant and and hundreds of people have weighed in on the answer with some very confusing words that I don’t understand.

Apparently, if you ask nicely they will tell you the password, but where’s the challenge in that?

Mathematician Clifford Stoll has turned his attention to the most popular method of pizza consumption and concluded that it is “remarkable”.

Stoll reports that pizza prefers a Gaussian curvature despite being partially flat and having no natural curvatures. Humans correct this by folding the slice in half lengthwise using mathematician Carl Gauss’s “theorem egregium” or “remarkable theorem.” This improves the slice’s rigidity and makes it easier to eat.

So if you don’t fold your pizza when eating, you’re doing it wrong. Another of life’s great debates has been solved by math.

At any rate, if you’re good with numbers or you just want to watch a guy get super excited about pizza math, you can check out the video below. [click to continue…]


A team of mathematicians from Liverpool University have set their minds to work defusing any potential conflicts over who can lay claim to the largest slice of a pizza.

Their effort builds on previous research in the field of exotic pizza slicing, which showed that a pizza could be sliced into six curved slices which could then be sliced in half to produce 12 identical slices, a seen in the first example below. The more recent approach is similar but involves producing an odd number of straight sides which could then be cut up into equal slices, as seen in the second example below.

This method could then be reproduced indefinitely, as seen in the final example below – increasing the number of sides and even adding notch embellishments in a process that will leave you with a cold pizza, pissed guests and a new war over who gets slices with crust.

If you find yourself eternally irked by uneven pizza slice sizes, or continually bickering over who gets the biggest one, you need the pizza protractor.

The protractor features a guide to measure out either six or eight perfectly-proportioned slices as well as a cutting blade – all in a one-piece, easy to clean device.

The pizza protractor is currently available for pre-order, although a release date hasn’t yet been announced.

venn diagram platter

What do veggies and pita chips have in common? This Venn Diagram Serving Platter has the answer. Dip.

Dip is the answer to all things.

This unique platter was designed by artist Thomas Both, and it features two stoneware plates that have been merged together to form a… well, you know. If you’re looking for a housewarming gift for a mathematician, then I think you’ve found it.

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.

Chocolate Mill

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.

science cake

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.
