When people say they are “bad at math,” they usually mean that they had trouble with algebra, although if you corner them and ask the right questions you can usually make them realize that they use algebra all the time without noticing it. This leads to valid criticisms of how we teach math, but it doesn’t mean we’re a nation of math idiots.

Besides a reason to enjoy baked goods while feeling mathematically in-the-know, just what is π anyway?

The art of origami has been going through a renaissance over the past 30 years, with new designs being created at ever-increasing levels of complexity. It’s no coincidence that this rise in origami complexity has emerged at the same time scientists, mathematicians and origami artists themselves have been discovering more and more of the mathematical rules that govern how paper folding works.

Back in 2012, more North Carolinians voted for Democrats than Republicans in North Carolina’s Congressional elections. But Republicans ended up winning nine out of the state’s 13 seats that year. Those numbers piqued the interest of researchers at Duke, who decided to seek a mathematical explanation for the discrepancy. They recently published a study with their results.

Henry Segerman and Saul Schleimer paint beautiful shadows based on the maths of stereographic projection, a method originally used by cartographers to map the Earth
