This week's Sunday Puzzle looks like a mathematical equation. Well, it *is* a mathematical equation. But hidden in that equation is a poem. Can you recite it back to us? » 12/28/14 1:45pm Today 1:45pm

The coaster was designed by three mechanical engineering juniors and built in the span of a week by the incoming freshmen who would ride its wooden rails. In early designs, the coaster even had an internal loop. Unfortunately, MIT's Environment Health and Safety department said "no upside-down people. Period." » 12/27/14 7:48am Yesterday 7:48am

Over at *Prooffreader*, data nerd extraordinaire David Taylor has charted the most-used words from pop song titles by decade, from 1890 (which, who even knew *Billboard *rankings have existed since the 19th Century?) to present. The most common words from the 2010s? "Hell," "Yeah," "We," "Fuck," and "Die." Sounds about… » 12/17/14 3:20pm 12/17/14 3:20pm

Computer animation is one of those delightful intersections of science and art, but when we're cooing over concept art and character designs, it's easy to forget all the math that goes into bringing these movies to life. This video explains the calculations behind the characters. » 11/15/14 2:00pm 11/15/14 2:00pm

When enough contrarians actively resist mainstream trends, their nonconformity may actually align. Ergo beardsplosion. » 11/12/14 1:20pm 11/12/14 1:20pm

Today's puzzle will be posed in two halves. The first half is a classic riddle – in fact, I suspect many of you will have heard it before. The second half, however, is an extension of the riddle that reveals its most common solution be be insufficient. » 10/19/14 11:00am 10/19/14 11:00am

We've all been there. You pick up a slice of pizza and you're about to take a bite, but it flops over and dangles limply from your fingers instead. The crust isn't stiff enough to support the weight of the slice. Maybe you should have gone for fewer toppings? No. There's no need to despair. » 10/10/14 9:30am 10/10/14 9:30am

So this is fun. For the past few months, "illustrator, math teacher, and professional dad" Nathan Shields has been perfecting the design on a pan-mounted apparatus that lets his family make spirographic pancakes (aka "spirocakes"). » 10/08/14 1:40pm 10/08/14 1:40pm

An eighth grader by the name of Cody was asked by an instructor to convert an algebraic expression into a word problem. Cody was happy to oblige – and with an ample helping of *Star Wars *references, no less. » 10/05/14 2:40pm 10/05/14 2:40pm

Several years ago, retired military officer Guan Baihua invented what may be the ultimate geometry geek bicycle. The front wheel is a pentagonal curve, and the back wheel is a reuleaux triangle (a triangular curve). It seems like it shouldn't work, but it does — and beautifully! » 9/30/14 10:29am 9/30/14 10:29am

Those last few nickels and dimes leftover on your metro card, and the time it takes to add on to it, can really add up. So what's the frugal (and time-crunched) train traveler to do? Mathematics has the answer. [**UPDATE**] » 9/08/14 1:31pm 9/08/14 1:31pm

Earlier this month, Iranian-born Stanford mathematics professor Maryam Mirzakhani became the first woman to be awarded the prestigious Fields Medal in the prize's nearly 80-year history. Perhaps unsurprisingly, she has some pretty solid advice to offer on making one's way through the world. » 8/30/14 8:00am 8/30/14 8:00am

Geometric Music is a free app (download here, or fiddle online) that takes sounds recorded from your environment and assigns them on-screen geometric shapes. Manipulating the shapes and arranging them relative to one another allows the user to build looping, layered musical pieces. » 8/21/14 9:30am 8/21/14 9:30am

Stanford mathematician Maryam Marzakhani has just won the Fields Prize, often called the Nobel Prize in mathematics. The first woman to win the prize, Marzakhani is best known for her work on curved surfaces, including on spheres and hyperbolic objects. » 8/13/14 10:30am 8/13/14 10:30am
