What would life be like with just two (or four) dimensions?
More on numerosity and number cognition with Brian Butterworth – this time discussing research with animals.
How do you measure with numbers if they have no size?
Imagine a two-dimensional world — you, your friends, everything is 2D. In his 1884 novella, Edwin Abbott invented this world and called it Flatland. Alex Rosenthal and George Zaidan take the premise of Flatland one dimension further, imploring us to consider how we would see dimensions different from our own and why the exploration just may be worth it.

Infinity can throw up some interesting paradoxes, from filling Hilbert’s Hotel to painting Gabriel’s Trumpet… Mark Jago is a philosophy lecturer with a background in computer science.
It isn’t easy holding complex sentences together (just ask a conjunction or a subordinate), but the clever little comma can help lighten the load. But how to tell when help is really needed? Terisa Folaron offers some tricks of the comma trade.
The ratio of a circle’s circumference to its diameter is always the same: 3.14159… and on and on (literally!) forever. This irrational number, pi, has an infinite number of digits, so we’ll never figure out its exact value no matter how close we seem to get. Reynaldo Lopes explains pi’s vast applications to the study of music, financial models, and even the density of the universe.
What’s so special about Leonard da Vinci’s Vitruvian Man? With arms outstretched, the man fills the irreconcilable spaces of a circle and a square — symbolizing the Renaissance-era belief in the mutable nature of humankind. James Earle explains the geometric, religious and philosophical significance of this deceptively simple drawing.
