Marianne Freiberger

Marianne Freiberger is Editor of Plus. She joined Plus in 2005 after doing a PhD and then a three year postdoc at Queen Mary, University of London. As a researcher she worked in complex dynamics, the area of pure maths that has given us the Mandelbrot set. In the world of maths communication she has been Editor-in-Chief of the Mathscareers website, given presentations to mathematicians about how to communicate their work to a wider audience, and to journalists about how to deal with maths in the media. She has been a TEDx speaker and an invited speaker at the International Congress of Mathematicians in 2010.

Together with Rachel Thomas, Marianne has co-authored several popular maths books including Numericon: A journey through the hidden lives of numbers and Understanding numbers, and were editors on the book 50: visions of mathematics. They were Science Editors for the Discovery+ documentary series Universe Unravelled about the work of the Stephen Hawking Centre for Theoretical Cosmology. 

In October 2022 Marianne and Rachel received a SPI-M-O Award for Modelling and Data Support (SAMDS) from the UK's Scientific Advisory Group for Emergencies. This award recognised their work with the JUNIPER modelling consortium to provide a wide audience (including public, press, policy makers and government) with clear and accessible explanations of some of the maths that was vital in responding to the COVID-19 pandemic.

Pi

Easy as pi?

This article explores this most beautiful of numbers. Find out its definition, why its value can only ever be approximated, what it has to do with waves, and why it contains the history of the Universe.

There's a romantic vision of mathematicians only needing pen and paper for their work. Here's why this is far from the truth when it comes to mathematical modelling, used to solve problems in the real world.

Network of people

Six degrees of separation

We explore the maths that helps explain this well-known phenomenon, which says that any two people around the world are likely to be connected through a surprisingly short chain of acquaintance links.

Stochastic spread

When a new infectious disease enters a population everything depends on who catches it — superspreaders or people with few contacts who don't pass it on.  We investigate the stochastic nature of the early stages of an outbreak.
