We talk about a play that explores the fascinating mathematical collaboration between the mathematicians GH Hardy and Srinivasa Ramanujan.

Are you an emerging engineer, mathematician or scientist who doesn't have the support of a school, university, or other research organisation? Then the Spirit of Ramanujan project might be able to help.

A hundred years ago Ramanujan was elected FRS. Here is a look at the maths that gained him the title.

The self-taught genius would have turned 129 in December.

A fascinating discovery sheds new light on the work of the Indian mathematician Srinivasa Ramanujan.

The self-taught Indian genius would have turned 127 this month.

Victoria Gould has always known she would be an actor, and went straight from studying arts at school to running her own theatre company. But she eventually had to come clean about her guilty secret - she loves maths - and has since managed to combine a career as a research mathematician and teacher with a successful acting career on television and in theatre. She tells Plus why she needs to use both sides of her brain.

Mathematics takes to the stage with A disappearing number, a work by Complicite, inspired by the mathematical collaboration of Hardy and Ramanujan. Rachel Thomas went to see the play, and explains some of the maths. You can also read her interview with Victoria Gould about how the show was created.

Memory is fundamental to the way we think, and we use it in almost every activity. But most of us cannot imagine approaching the level of world record holder Hiroyuki Goto, who memorised and recited 42,195 digits of pi! Rob Eastaway asks if mere mortals can learn anything useful from such incredible feats of memory, and gives some hints on how to remember numbers.
