Back in the days before smart phones with GPS functions became ubiquitous we had maps. Remember how hard it was to fold them? Mathematicians have struggled with map folding problems for generations. But a recent insight suggests there might be another way to approach these problems, making an unlikely connection between combinatorics, origami and engineering.
In soccer a coin toss is used to decide who goes first in a penalty shootout and similarly in American football a coin decides who plays offence in overtime. But is this really fair? This article explores an alternative.
Space is the stage on which physics happens. It's unaffected what happens it and it would still be there if everything in it disappeared. This is how we learn to think about space at school. But the idea is as novel as it is out-dated.
The number pi can be expressed beautifully in terms of infinite sums. For practical purposes though, these sums are rather disappointing: they converge slowly, so you need to sum a large number of terms to get accurate estimates of pi. Here's a clever way to make them converge faster.
