How ships navigate a sphere, the math and maps behind great circle routes
On a flat chart, the shortest ocean route looks like a curve, but that's just a trick of the map projection. Here's how ...
In algorithms, as in life, negativity can be a drag. Consider the problem of finding the shortest path between two points on a graph — a network of nodes connected by links, or edges. Often, these ...
The original version of this story appeared in Quanta Magazine. If you want to solve a tricky problem, it often helps to get organized. You might, for example, break the problem into pieces and tackle ...
