Watch geometer/topologist Caleb Ashley explain the parallel postulate on Numberphile.
Being a mathematician, I often get asked if I’m good at calculating tips. I’m not. In fact, mathematicians study lots of other things besides numbers. As most people know, if they stop to think about it, one of the other things mathematicians study is shapes. Some of us are especially interested in the symmetries of… Read more »

This is a guest post by researcher Audace Dossou-Olory of Stellenbosch University, South Africa. In assignment problems, one wants to find an optimal and efficient way to assign objects of a given set to objects of another given set. An assignment can be regarded as a bijective map $\pi$ between two finite sets $E$ and $F$ of… Read more »
This is a guest post written by David Nkansah, a mathematics student at the University of Glasgow. Around the fourth century BC, the term ‘Mathematics’ was defined by Aristotle as the “science of quantity”. It’s my own experience as a young mathematician to say this definition, although correct in its own right, poses a problem… Read more »
