A childhood story from EH:
Maths came easily to me until A-level, so I have no recollectionof any issues. After GCSE a teacher did tell my parents that I shouldrethink my ambition to do a maths degree as I would soon hit myceiling. He was partly right. I struggled for ages with the languageof differentiation until I got the visual picture. Since then maths hasbeen hard work to understand, though I usually get through withenough work. Making visualisations and images really helps me.Around the same time (GCSE) I came across the Penrose tilingfor the first time and was fascinated. I remember working for agestrying to find a version with seven fold rotational symmetry ratherthan five. I drew lots of pictures, but did not get anything to work.I am now a mathematician, having done my PhD on the Penroseand related tilings. And the problem? I eventually solved it (and thegeneral case) and it became my second published paper.
