Needless to say, as I look back on my childhood now, I can identify where certain seeds were planted: the interest in cars, the fascination with tinkering – both of which came from my dad – and now the first flowerings of what you might call the design engineer’s mind, which even more than a mathematician’s or physicist’s involves combining the artistic, imaginative left side of the brain – the ‘what if?’ and ‘wouldn’t it be interesting to try this?’ bit – with the more practical right side, the bit that insists everything must be fit for purpose.
