My dad says that ever since I could talk I was always asking him questions about things around me – Why is grass green? How big is the Earth, What’s the Sun made of? Things like that. I realised at school that science was about trying to answer a lot of the questions that most interested me so I studied as much science as I could. I took biology, chemistry and physics as single sciences to GCSE. When I started my A levels I wasn’t sure if I was going to study marine biology or physics at uni and I only decided I was going to do physics at the end of my AS year.
