Grochow is among a growing chorus of researchers who point out that when it comes to finding connections in big data, graph theory has its limits. A graph represents every relationship as a dyad, or ...

Sure, you can cut a pie into pieces, but what if it’s in four dimensions? Using spectral graph theory, mathematicians have solved a decades-old problem. Graph theory uses nodes and edges (dots and ...

Microsoft Excel is designed to organize and interpret small and large amounts of data. Building a curved graph in Excel based on X and Y data points is fairly simple. You begin by adding the data ...

Bar graphs seem like one of the simplest ways to represent data. Many people assume that the longer the bar, the bigger the number it represents. Sometimes bar graphs represent an average not a total ...

For most of us, or perhaps all of us, it's impossible to imagine a world consisting of more than three spatial dimensions. Are we correct when we intuit that such a world couldn't exist? Or is it that ...

Dante Alighieri imagined hell as being a hole in the Earth the shape of a giant ice cream cone. With a tip at the centre of the Earth, hell was covered by a vaulted roof that was part of the Earth's ...

String theory is a purported theory of everything that physicists hope will one day explain … everything. All the forces, all the particles, all the constants, all the things under a single ...

Receive emails about upcoming NOVA programs and related content, as well as featured reporting about current events through a science lens. The engineer whips out a protractor and straightedge. That’s ...

Mathematicians are “reinventing the wheel” by giving it a new shape. Their newly imagined wheel looks like a many-dimensional guitar pick, and it could theoretically roll in ways beyond our ...
