Myths of maths

We debunk some common mathematical misconceptions.

Happy birthday, George Boole!

Modern computers wouldn't be possible without George Boole, who died before light bulbs even came on the market. We celebrate his 200th birthday with a look at the man and his work.

Science fiction, science fact: reports from the frontiers of physics

What is time? What is space? Are there parallel universes? Join Plus and FQXi on a journey exploring these and many more questions on the frontiers of physics. What do you think is science fiction and what do you think we close to proving are science facts? Find out more about scientific developments in these areas, ask your own questions and debate the answers!

Teacher package: ProofsThe notion of proof lies at the very heart of maths: it's when it comes to proving things that mathematicians let lose their genius and creativity, and in the process often discover unexpected surprises or deep philosophical issues. But proofs can also be daunting. So to help you and your students along, we've brought together a range of Plus articles on proofs.
Teacher package: Graphs and networksThis teacher package brings together all Plus articles on graph and network theory. Graphs and networks turn up in many real-life problems, from neuroscience to telecommunications. In the UK curriculum, they make a frequent appearance in the area known as decision maths. Our articles explore a wide range of related topics, from simple algorithms to complex network topologies.
Teacher package: On thin ice - maths and climate change in the Arctic In this issue's teacher package we look at some of the maths and science behind a recent expedition to the Arctic. The aim of the Catlin Arctic Survey was to gather data on ice thickness that will help to predict when the North Pole sea ice cover will melt, an event that will have dramatic consequence for the Arctic ecosystem and the Earth's climate as a whole. Plus was commissioned by Catlin Arctic Survey Education to produce mathematics and science enrichment material for ages 14 to 19 (key stages 4 and 5). The toolkits look at climate and sea ice models, GPS and cartography, how to predict future climate trends, and how to present statistical evidence.
