Zoe Herriot
Zoe Heriotwas a young astrometricist, first class, and astrophysicist on board Station 3 (aka The Wheel) when she met the Doctor and Jamie McCrimmon. She introduced herself to them as 'astrophysicist, pure-mathematics major', to which her colleague Dr Gemma Corwyn added 'with honours'. Zoe had a photographic memory, and was described by her colleagues as 'the librarian'. her training left her emotionally underdeveloped, having been taught the value of logic. This lack of emotion led to confilct with some of her colleagues, who challenged her about her apparent lack of personal interest in the Wheel when it was about to be struck by meteorites. When she met the Doctor, Zoe was presented with a case study in how illogical, intuitive, action and instinct could be successful.
Biography
As Zoe became more aware that there was more to knowledge than mere facts, she decided to hide on the TARDIS. She realised that she had learnt as much as she could on the Wheel, where her abilities and role were compartmentalised and defined. Zoe had become ready to discover the universe, and her place in it.
When visiting the War Museum on Dulkis, Zoe was reminded of 'the old atom test islands on earth'. At the same time, she was dissmisive of the Quarks, claiming 'they're only robots' (The Dominators)
