Description

Have you ever tried walking in a straight line with your eyes closed? It’s remarkably hard to keep on track. Dr Emily Grossman explains why. Subscribe for regular science videos: http://bit.ly/RiSubscRibe

Visual information plays a key role in the way we orient ourselves. Hanging on to visual reference points allows us to keep walking in a straight line. Take away the ability to see these reference points and walking straight becomes nearly impossible. Internal systems, such as the vestibular system in your inner ear, also help us orient ourselves in three dimensional space. These systems, however, aren’t perfect.

Dr. Emily Grossman is an expert in molecular biology and genetics, with a Triple First in Natural Sciences from Queens' College Cambridge and a PhD in cancer research. She also trained and worked as an actress, and now combines her skills in her work as a science broadcaster and educator; teaching maths and all three sciences at all academic levels and explaining science for a wide range of TV and radio programmes. She recently completed a season as resident science expert on ITV's The Alan Titchmarsh Show, and was a member of the panel of experts for two series of Sky1's celebrity panel show Duck Quacks Don't Echo, hosted by Lee Mack. She has appeared as a science expert on ITV's This Morning, Channel 4’s Food Unwrapped, Sky News, BBC1's The One Show, and London Live’s Not the One Show, has been interviewed several times on Radio 4’s Last Word, Radio 5 live’s Daily Bacon, BBC World Service’s Newshour and LBC Radio, and is a regular guest on the Guardian Science Weekly podcast.

Emily has hosted science events for the Academy of Medical Sciences and at the Royal College of Physicians in Edinburgh, she has run workshops and given talks for The Royal Institution, she has performed at Science Showoff at the Bloomsbury Theatre, and she has presented many interactive science shows in schools and at science festivals. She is also a communication skills trainer for the Famelab International science communication competition - running master-classes for competition finalists across the globe - and is a judge for the Institute of Ideas Debating Matters Competition. Emily has taught science and maths at two London schools and the Manchester Science Museum, and has tutored over 150 private students. She is also the new voice of Oxford University Press’s online resource, MyMaths.
