## News from the world of Maths

If you're not sure how maths is relevant to real life, then go to see this year's popular lectures put on by the London Mathematical Society.

At last month's Cambridge Science Festival we had great fun trying out a hands-on (or rather feet-on) activity based on one of our favourite puzzles – the bridges of Königsberg. We were really pleased with how it went, so we thought we'd share our game for others to put on at their own science or maths event.

The search for the missing Malaysia Airlines' flight MH370 was dramatically narrowed last week due to a mathematical analysis of satellite signals from the plane. Careful analysis of just a handful of data points has focussed the search on an area in the southern Indian Ocean.

The ability to see order in chaos has won the mathematician Yakov G. Sinai the 2014 Abel Prize.

As your cereal tumbled into your bowl this morning, were you daydreaming of sand dunes or snowy mountains? It wouldn't be surprising given the drab grey skies outside. But now you have another excuse: the cereal, sand and snow can all be examples of *granular flows*.

Yesterday cosmologists at the University of Cambridge delivered their verdict on a major breakthrough that rocked science this week: the announcement of the BICEP2 project of direct evidence for an inflationary theory of the Universe and the existence of gravity waves

Data from BICEP2 gathered in the South Pole reveals swirls in the CMB, the first image of gravitational waves and evidence for inflation.

We love every number equally but there is no denying the fame, ubiquity and usefulness of the number pi…
