One of the reasons I dreaded math class was the looming feeling that what I learned would turn out to be useless. No matter how hard I tried, I could not imagine a situation outside of school when I would need to know how to graph a logarithm or find the degree of an unknown [...]

Part of my online life includes editorial duties at ResearchBlogging.org, where I serve as the Social Sciences Editor. Each Thursday, I pick notable posts on research in anthropology, philosophy, social science, and research to share on the ResearchBlogging.org News site. To help highlight this writing, I also share my selections here on AiP. Happy New Year! Bloggers [...]

There are big changes underway in how kids across the country are learning math. Forty-four states plus the District of Columbia have adopted a common set of standards that detail what students should understand and be able to do at each grade level, from Kindergarten through the end of high school. Known as the Common Core State Standards, [...]

The passing of the mathematician Benoit Mandelbrot has triggered in me a wave of nostalgia for the 1980s, when Mandelbrot and other researchers seemed to be creating a scientific revolution. They hoped that sophisticated new mathematical techniques, plus increasingly powerful computers, could help them fathom a wide range of complex, nonlinear phenomena—from brains and immune [...]

I suffer from eschatological obsession. That is, I spend lots of time brooding about ends. So the cover of the September Scientific American—which reads simply "the end."—made me all shivery, like when I hear the spooky sitar opening of The Doors’ apocalyptic rock poem "The End." (I’m never more Freudian than when I hear Morrison’s [...]

Math can be a beautiful, immersive, full-body experience, according to the creators of the newly opened Museum of Math, or MoMath, in New York City. A sculpture that lights up and plays music, a touch-screen floor that turns into a maze and a square-wheeled tricycle that one can ride around a bumpy track are just [...]

James Abram Garfield was born on this day, November 19, in 1831. Had an unstable, delusional stalker’s bullets and nineteenth-century medical “care” not cut short his life just six months into his presidency, he would be 181 today (more on that later). Garfield was an intelligent man who studied some math in college, but contemporary [...]

I was at a math conference last week, and one of the other attendees brought a puzzle. I am a pretty slow puzzle-solver, so it will be a while before I figure out how to assemble those five pieces to get this. Three views of the assembled puzzle. Saul Schleimer, a mathematician at the University [...]

For decades, scientists have been trying to solve a tough question: if the Internet runs out of cat pictures, can we generate more using advanced mathematics?* A paper posted on the arxiv earlier this month by mathematicians Kathryn Lindsey and the late William Thurston calms fears about “peak cat.” In the paper, they describe a [...]

On Tuesday, Scientific American turns 167 years old. It doesn’t exactly look like the kind of anniversary we usually celebrate, with our decimal normative number system that overvalues ending zeroes and fives, but 167 is a pretty neat number. First of all, we can insert two symbols into it to get a correct mathematical statement: [...]

William Thurston, whose geometrization conjecture changed the fields of geometry and topology and whose approach to mathematics and mathematics education has reverberated throughout the mathematical world, died on August 21 following a battle with cancer. He has appeared in the pages of Scientific American in the article The Mathematics of Three-Dimensional Manifolds, which he co-wrote [...]

In an opinion piece for the New York Times on Sunday, political science professor Andrew Hacker asks, “Is Algebra Necessary?” and answers, “No.” It’s not just algebra: geometry and calculus are on the chopping block, too. It’s not that he doesn’t think math is important; he wants the traditional sequence to be replaced by a [...]

I hope you’re ready for your big Pi Approximation Day party tomorrow. You might have observed Pi Day on March 14. It gets its name from 3.14, the first three digits of the ratio of a circle’s circumference to its diameter. Always on the lookout for excuses to eat pie, some geeky math types also [...]

Last Wednesday night I attended a “Math Encounters” program co-sponsored by the soon-to-open Museum of Math in New York City. In 2008, Glen Whitney, a mathematician and former hedge fund manager, was dismayed to learn that a small museum dedicated to math in Long Island was closing. He decided to start a math museum himself. [...]

As my Amtrak train rolled past the “Lancaster” sign, the window view alighted on the upright figure of an Amish farmer and his mule-team-pulled hand plow, working the verdant Pennsylvania land just as his forefathers have done here for more than two centuries. I remembered that I was only some 33 miles from Dover, Pa., [...]

Have you ever watched “Mean Girls”? It’s one of the movies before Lindsey Lohan really began to let her career slip. She plays Cady, a smart girl, homeschooled by her parents as they lived in Africa until her high school years, where, desperate to fit in AND to “get the guy”, she dumbs down her [...]

This is a follow up to my last post about Science Video Brainstorming. Thank you everyone who has kindly donated toward my trip to VidCon 2012! I have enough for a plane ticket! Please continue your generous donations in any amount so I can have a place to stay and food to eat! Recall that [...]

This year I’ve been co-writing “Mathematics, Live,” an interview series for the Association for Women in Mathematics newsletter. In my interviews I’m “listening in” on conversations between pairs of female mathematicians. The first interview appeared in the May/June issue of the newsletter (password required). In it, I talked with mathematicians Laura DeMarco of the University [...]

I’ve been thinking about the hairy ball theorem a lot recently. Because I have the sophisticated sense of humor of a twelve-year-old just got a haircut, and I am newly reminded of my cowlicks. At this length, I’m much more aware of my hairs as vectors than I was when they were longer. A vector is [...]

On Monday, Harald Helfgott of the École Normale Supériure in Paris posted a proof of one of the oldest open problems in number theory to the preprint repository arxiv. The ternary Goldbach conjecture, like so many questions in number theory, is easy to state but hard to prove. Every odd number greater than 5 can [...]

Many math teachers have a hands-on approach to their subject, but those hands aren’t usually covered in finger paint. Scott Goldthorp, however, sometimes teaches messy math classes. Goldthorp, a teacher at Rosa International Middle School in Cherry Hill, New Jersey, was the grand prize winner of the inaugural Rosenthal Prize for innovation in math teaching, [...]

Image: Design Shack In the current issue of the Association for Women in Mathematics newsletter (password required), Anne Carlill asks where the female mathematicians are on Twitter: “I found that the only female mathematicians or math educators I followed were Nalini Joshi in Sydney and Fawn Nguyen in California. In contrast there are about 15 [...]

Today I have a piece in Slate about that pi meme that’s been going around. According to the meme, your life story is encoded in pi somewhere. My life story would probably include the word “Evelyn” at some point. (I’m going out on a limb, but stay with me.) In a code that assigns the [...]

There’s a contest going on right now that could reward you for letting your geek flag fly. Spoonflower, a fabric design website, is hosting a “geek chic” design contest that closes April 23. It’s held in conjunction with Robert Kaufman Fabrics, and the lucky winner will get to create a fabric collection for Robert Kaufman. I had [...]

Rather appropriately, April 1st is the 91st day of the year, at least in non-leap years such as 2013. 91 might look innocent, but it’s a sneaky little number because 91=7×13. That might not seem sneaky to you, but I’m here to tell you why it is. Every whole number can be broken down into [...]

March Madness always sneaks up on me. I mean, I know that March has started because my dad’s birthday and my wedding anniversary are right at the beginning of the month, but I always end up scrambling to make my NCAA basketball tournament picks the day before games start. Mathematician Jordan Ellenberg has taken the [...]

On the one hand, I like Pi Day because I get to eat pizza and/or pie, and I like things that get people excited about math, but on the other hand, I’m an adult, and I get to eat pizza and/or pie whenever I want, Pi Day or no. Like Matt at Math Goes Pop, [...]

Practice makes progress, if not perfection, for most things in life. Generally, practicing a skill—be it basketball, chess or the tuba—mostly makes you better at whatever it was you practiced. Even related areas do not benefit much. Doing intensive basketball drills does not usually make a person particularly good at football. Chess experts are not [...]

In Tyson Schoeber’s class at Nootka Elementary School in Vancouver, 15 fourth through seventh graders struggle to read, write or do math at a level near that of their peers in other classes. Ten-year-olds have entered Schoeber’s program, called THRIVE, virtually unable to read independently (see “One Man’s Mission to Save Struggling Students”). Yet Schoeber [...]

As our month of SciArt of the Day winds down, I had to share this image. For me, this is a touchstone of what makes wonderful science-art: marrying metaphors from past and present, science and myth. The idea that art and science represent two cultures, as C.P. Snow described is a curious one. Art, or [...]

At their most fundamental level, brains are made up of neurons. And those neurons collectively comprise the two main types of brain tissue: white matter is made up primarily of axons, and grey matter is made up of synapses, or the connections between neurons. (Want a primer on the neuron? Check out this explainer post [...]
