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.
Why does time only ever move in one direction? We talk to philosophers of physics Jeremy Butterfield and David Wallace, as well as the eminent Roger Penrose about the puzzle time poses to physicists and what it has to do with the Big Bang and the second law of thermodynamics.
